Acrylic paint
In today's colorful paint world, acrylic paint is like a bright star, with its excellent performance and a wide range of applications, in many paint varieties stand out. It not only adds brilliant colors to our lives, but also provides a solid protective barrier for all kinds of items. Today, let's embark on an exciting journey to explore acrylic paint and learn more about its unique charm and value.
1, acrylic paint definition and composition
Acrylic paint, as the name suggests, is a kind of paint with acrylic resin as the main film-forming substance. Acrylic resin is a polymer compound prepared by polymerization of acrylic ester and methacrylate monomer. In addition to acrylic resins, acrylic paints usually contain pigments, solvents, additives and other ingredients.
Pigments give paint a variety of colors and hiding power, common pigments are titanium dioxide, iron oxide red, phthalocyanine blue and so on. Solvents are used to adjust the viscosity of the paint and drying speed, common solvents are xylene, butyl acetate and so on. There are many kinds of additives, such as leveling agents, defoaming agents, dispersants, etc., which can improve the construction performance and coating performance of the paint.
2, acrylic paint characteristics
Excellent weather resistance
Weather resistance is one of the most prominent characteristics of acrylic paint. It can withstand the long-term erosion of natural factors such as sunlight, rain, temperature changes, and ultraviolet radiation, while maintaining the freshness of the color and the integrity of the paint film. This makes acrylic paints excellent in outdoor applications, such as those used for building facades, billboards, Bridges, etc. For example, in some harsh climate areas, after years of wind and rain, the exterior walls of buildings coated with acrylic paint are still bright, without obvious fading and peeling phenomenon.
Good adhesion
Acrylic paint can be firmly attached to a variety of substrate surfaces, whether metal, wood, plastic, concrete or glass, etc., can form a tight bond. This good adhesion provides the object with reliable protection against the peeling of the paint film and corrosion of the substrate. For example, in automotive manufacturing, acrylic paint is often used to paint the body of the car to ensure that the paint film withstands vibration and friction during driving, and will not easily fall off.
Rapid drying
Acrylic paint has a faster drying speed, which greatly reduces the construction time and improves the work efficiency. Under appropriate environmental conditions, the film can usually be dried in a few minutes to a few hours, making the construction process more convenient. This feature has great advantages in some occasions that need to be put into use quickly, such as factory workshops, equipment maintenance, etc.
Chemical resistance
It has a certain chemical resistance, can resist acid, alkali, salt and other chemical substances erosion. This makes acrylic paint widely used in equipment and pipeline coating in chemical, petroleum and other industries, effectively extending the service life of equipment.
Environmental protection property
With the increasing demand for environmental protection, acrylic paint also performs well in environmental protection. It usually contains a low volatile organic compound (VOC) content and is less harmful to the environment and human health. At the same time, some water-based acrylic paints use water as a solvent, further reducing environmental pollution.
3. Detailed comparison of physical properties
Architectural decoration
(1) Exterior walls of buildings
Acrylic paint provides beauty and protection to the exterior walls of the building. Its weather resistance and color stability allow the building to maintain a brand new appearance after many years. Different color and gloss options allow architects to realize a variety of unique design concepts.
(2) Doors and Windows
Doors and Windows are often exposed to the outside environment and need to have good weather and corrosion resistance. Acrylic paints are able to meet these requirements while providing a rich choice of colors that harmonize doors and Windows with the overall style of the building.
(3) Interior wall
Acrylic paint is also used in interior decoration. Its environmental protection and low odor characteristics make it suitable for residential, office and other places of wall painting.
Industrial protection
(1) Bridges
Bridges are subjected to many factors such as wind and rain, vehicle loads, etc., and need to be protected by coatings with good weather resistance and anti-corrosion properties. Acrylic paint can effectively prevent the corrosion of bridge steel structure and extend the service life of bridge.
(2) Storage tank
The chemical substances stored in the chemical storage tank are corrosive to the tank, and the chemical corrosion resistance of acrylic paint can provide reliable protection for the storage tank.
(3) Pipeline
Oil, natural gas and other pipelines need to prevent external factors from corroding the pipelines during transportation. The anti-corrosion properties of acrylic paint make it an ideal choice for pipeline coating.
Vehicle repair
The car will inevitably appear scratches and damage in the process of use, and it needs to be repaired and painted. Acrylic paint can match the color and gloss of the original paint of the car to achieve a high quality repair effect, so that the repair part is almost invisible.
Wood furniture
(1) Solid wood furniture
Acrylic paint can provide a beautiful appearance and protection for solid wood furniture, increasing the wear and water resistance of furniture.
(2) Wood-based panel furniture
For wood-based panel furniture, acrylic paint can seal the surface of the panel and reduce the release of harmful substances such as formaldehyde.
Ship painting
Ships have been sailing in the Marine environment for a long time, facing the test of high humidity, salt spray and other harsh conditions. The weatherability and corrosion resistance of acrylic paint can protect the hull and superstructure of the ship, ensuring the safety and beauty of the ship.
4, acrylic paint construction method
Surface treatment
Before construction, ensure that the surface of the substrate is clean, smooth, and free of contaminants such as oil, rust, and dust. For metal surfaces, sandblasting or pickling is usually required to increase adhesion; For wood surface, need to be polished and deburring treatment; For the concrete surface, it is necessary to sand, repair cracks and remove release agents.
Construction environment
The temperature and humidity of the construction environment have an important effect on the drying and performance of acrylic paint. In general, the construction temperature should be between 5 ° C and 35 ° C, and the relative humidity should be below 85%. At the same time, the construction site should be kept well ventilated to facilitate the volatilization of solvents and the drying of paint film.
Stir well
Before using acrylic paint, the paint should be fully stirred to ensure that the pigment and resin are evenly distributed to ensure the performance and color consistency of the paint.
Construction tool
According to different construction requirements, spray guns, brushes, rollers and other tools can be selected for construction. The spray gun is suitable for large area painting and can obtain uniform paint film; Brushes and rollers are suitable for small areas and complex shapes.
Number of coating layers and thickness
According to the specific application scenario and requirements, determine the number of layers of coating and the thickness of each layer. In general, the thickness of each layer of paint film should be controlled between 30 and 50 microns, and the total thickness should meet the relevant standards and specifications.
Drying time
During the construction process, the drying time should be controlled according to the paint instructions. After each layer of paint film has dried, the next layer can be painted.
5, acrylic paint quality detection
Visual inspection
Check the color, gloss, flatness of the paint film and whether there are defects such as hanging, orange peel, and pinholes.
Adhesion test
The adhesion between the paint film and the substrate meets the requirements by means of marking method or pulling method.
Weather resistance test
The weatherability of paint film was evaluated by artificial accelerated aging test or natural exposure test.
Chemical resistance test
Soak the paint film in acid, alkali, salt and other chemical solutions to test its corrosion resistance.
