Acrylic paint
In today's colorful paint world, acrylic paint has become the darling of many industries and consumers with its unique advantages and wide range of application fields. Today, let's delve into the mystery of acrylic paint and fully understand its characteristics, advantages, applications and construction points.
1. The definition and development of acrylic paint
- Acrylic paint, as the name suggests, is a type of paint with acrylic resin as the main film forming substance. Acrylic resin is a resin made by copolymerization of acrylates, methacrylate esters and other olefins.
- Its development can be traced back to the middle of last century. With the continuous progress of the chemical industry, the synthesis technology of acrylic resin has gradually matured, making acrylic paint available. Early acrylic paints were mainly used in the automotive industry, and were soon favored by the market due to their excellent weather resistance and gloss retention. With the continuous improvement and innovation of technology, the performance of acrylic paint continues to improve, and the application range is increasingly wide, from construction, shipbuilding to industrial corrosion prevention and other fields, you can see its figure.
2, the composition of acrylic paint analysis
Acrylic paint is usually composed of the following main ingredients:
- Acrylic resin: As a core component, determines the basic properties of the paint, such as adhesion, weather resistance, hardness, etc.
- Pigments: Give paint color and cover. The type and quality of pigment will affect the color, durability and anti-corrosion properties of paint.
- Solvent: Used for dissolving resins and regulating the viscosity of paints to facilitate construction. Common solvents include organic solvents such as toluene, xylene, and some environmentally friendly water solvents.
- Additives: including leveling agent, defoamer, dispersant, etc., their role is to improve the construction performance of the paint, surface smoothness and prevent bubbles, precipitation and other problems.
These ingredients work together to make acrylic paint work best during construction and use.
3. the performance advantages of acrylic paint
Excellent weather resistance
Weatherability is one of the most prominent properties of acrylic paint. It can withstand the test of long-term sun exposure, wind and rain, temperature changes and other natural environments, and is not easy to fade, powder, peeling and other phenomena. This is because acrylic resins have good UV absorption and antioxidant properties, which can effectively protect the coating and substrate.
Excellent chemical resistance
Acrylic paint has strong resistance to acid, alkali, salt, solvent and other chemicals. This makes it excellent in the anti-corrosion coating of chemical, petroleum, electric power and other industries, and can effectively protect equipment and facilities from chemical corrosion.
Good adhesion
Acrylic resins can form strong bonds with a variety of substrate surfaces, including metal, wood, plastic, concrete, etc. This excellent adhesion ensures that the coating is not easy to peel off during long-term use, providing reliable protection for the substrate.
Rapid drying
Acrylic paint dries quickly and can form a hard coating in a short time. This not only improves the construction efficiency, reduces the construction period, but also reduces the construction cost.
Environmental protection and safety
Acrylic paints generally have lower volatile organic compound (VOC) emissions compared to conventional paints. This is more friendly to the environment and the health of construction workers, in line with the requirements of modern society for environmental protection and safety.
Easy to clean and maintain
Acrylic paint has a smooth surface, is not prone to dirt, and is relatively easy to clean. This allows surfaces coated with acrylic paint to remain clean and beautiful for a long time.
4, the application field of acrylic paint
Architectural field
Exterior wall painting: Acrylic paint provides a beautiful appearance and long-lasting protection for the exterior walls of buildings. Its excellent weather resistance resists climate change and UV erosion, keeping the color bright and shiny.
Roof waterproof: In the roof coating, acrylic paint can form a seamless waterproof film to effectively prevent rain leakage.
Interior decoration: Due to its environmental protection and low odor characteristics, it is also suitable for indoor wall and ceiling painting.
Automobile industry
Car body painting: give the car a bright appearance, while providing good weather resistance and scratch resistance, protect the body from the damage of the external environment.
Auto parts: such as bumpers, wheels and other parts of the painting, improve its corrosion resistance and wear resistance.
Shipbuilding industry
Hull outer plate: can resist the erosion of sea water and the influence of Marine climate, extend the service life of the ship.
Cabin interior: provides protection against fire, rust and corrosion.
Industrial protection
Chemical equipment: used for chemical plant reaction kettle, storage tank, pipeline and other equipment anti-corrosion coating, to prevent the corrosion of chemical substances.
Steel structure: Coating on the surface of steel structures such as Bridges and steel structure workshops to enhance their rust and corrosion resistance.
Furniture manufacturing
Wood furniture: Provides an aesthetically pleasing coating for furniture while protecting the wood from moisture, wear and stains.
Metal furniture: such as the painting of iron furniture, to increase its decorative and rust-proof properties.
5. acrylic paint construction points
Surface treatment
Before construction, the surface of the substrate must be thoroughly cleaned to remove pollutants such as oil, dust and rust.
For metal surfaces, it is usually necessary to sandblast or sand treatment to achieve a certain roughness and enhance the adhesion of the paint.
The surface of the wood needs to be polished to remove burrs and spines.
Construction environment
The temperature and humidity of the construction environment have an important effect on the drying and curing of the paint. In general, the appropriate construction temperature is 5-35 °C, and the relative humidity does not exceed 85%.
The construction site should be well ventilated to promote the volatilization of solvents and the drying of paint.
Construction method
Brush coating: suitable for small areas and complex shapes of the surface, but the construction efficiency is low.
Spraying: A uniform, smooth coating can be obtained, and the construction efficiency is high, but it requires professional equipment and technology.
Roller coating: Often used in large area of plane construction, simple operation, but the coating thickness is relatively thin.
Construction thickness
The coating thickness of construction should be controlled according to the type of paint and the requirements of use. A coating that is too thin may not provide adequate protection, while a coating that is too thick may cause problems such as poor drying and cracking.
Usually, the thickness of each coating is between 30 and 80 microns, and the total coating thickness depends on the specific situation.
Drying and curing
After construction, adequate drying and curing time should be given in accordance with the requirements of the paint product manual. During the drying process, avoid touching and contaminating the coating.
For the two-component acrylic paint, it should be mixed strictly in accordance with the ratio and used within the specified time.
6, acrylic paint selection and precautions
Choose the right variety
According to different application scenarios and needs, acrylic paint varieties with corresponding properties are selected. For example, for outdoor use, products with good weather resistance should be selected; For occasions with high anti-corrosion requirements, products with good chemical resistance should be selected.
View product quality and certification
Choose the products produced by regular manufacturers, and check the quality inspection report and certification certificate of the products to ensure that the products meet the relevant standards and requirements.
Consider construction conditions
According to the construction environment, equipment and technical level, choose the appropriate construction methods and corresponding paint products.
Pay attention to storage and shelf life
Acrylic paint should be stored in a cool, dry, well-ventilated place, away from direct sunlight and fire sources. At the same time, pay attention to the paint shelf life, beyond the shelf life of the product may affect the performance.
