Introduction of Songying Chemical Water-based Paint

I. Overview of water-based paint

 

1. Definition

 

Water-based paint is a kind of paint that uses water as a solvent or dispersion medium. Its main components include water-based resin, face filler, film-forming auxiliary, thickener, wetting agent, dispersant and other auxiliary agents. Compared with traditional oil-based paint, water-based paint has significant advantages in terms of environmental protection and construction convenience.

 

2. Characteristics

 

• Environmental protection: Water-based paint does not contain harmful solvents, such as benzene, formaldehyde, etc., which is non-toxic and harmless to the human body and the environment, reducing the emission of VOC (volatile organic compounds).

 

• Convenient construction: water-based paint dries quickly, and it usually only takes a few hours to dry, which improves the construction efficiency. At the same time, construction tools can be cleaned directly with water without consuming cleaning solvent.

 

• Rich colors: Water-based paint has rich color options, which can meet the decorative effect of different needs.

 

• Good durability: Water-based paint has good weather resistance and wear resistance, which can resist the erosion of sunlight, rain and other natural environments, and extend the service life of the coating.

 

II. The basic composition of water-based paint

 

Water-based paint is mainly composed of the following parts:

 

• Water-based resin: As the main substrate for film formation, it determines the main function of paint film.

 

• Face filler: provide color and covering power, while increasing the solids of the paint film.

 

• Film-forming auxiliary: helps the emulsion or dispersion particles to form a uniform and dense film after water evaporates.

 

• Thickeners, wetting agents, dispersants and other auxiliary agents: respectively play the role of improving the viscosity of paint, improving the wetting performance, and promoting the dispersion of fillers.

 

III. Construction process of water-based automotive paint

 

1. Prepare for work

 

• Ensure that the construction environment is dry and well ventilated.

 

• Remove old paint, oil and dirt from the surface of the car to make the surface clean and flat.

 

2. Primer construction

 

• Use a spray gun to apply a layer of water-based primer evenly.

 

• Pay attention to keep the distance between the spray gun and the surface of the car uniform and the paint spraying speed stable.

 

3. Surface paint construction

 

• After the primer dries, spray the water-based topcoat evenly.

• Similarly, the spraying distance and speed should be controlled to ensure that the coating is uniform.

 

4. Polishing treatment

 

• Use a polishing machine to polish the coating to improve the gloss and smoothness of the coating.

 

IV. Construction equipment of water-based automotive paint

 

1. Spray gun

 

• It is one of the most critical equipments in the construction of water-based automotive paint.

• The spray guns commonly used in the construction of modern water-based automotive paint include electrostatic spray guns and high-pressure airless spray guns, etc., which have the advantages of high spraying efficiency and uniform coating.

 

2. Polishing machine

 

• It is used to improve the gloss and smoothness of the coating.

 

3. Other auxiliary equipment

 

• Such as sandpaper, steam engine, etc., which are used for surface treatment before construction and detail processing after construction.

 

V. The difference between water-based paint and oil-based paint

 

1. Raw materials and production process

 

• Water-based paint: with water as the main solvent, the production process is relatively simple.

• Oil-based paint: with dry oil as the main raw material, it contains a large amount of organic solvents and has a complex production process.

 

2. Environmentally friendly

 

• Water-based paint: high environmental protection, no harmful gas emissions during construction.

• Oil-based paint: There is a greater risk of environmental pollution, and harmful gases will be released during construction.

 

3. Construction convenience

 

• Water-based paint: fast drying speed, easy to clean construction tools.

• Oil-based paint: the drying time is long, and it is difficult to clean construction tools.

 

4. Durability

 

• Water-based paint: the durability is relatively good, but it is greatly affected by the external environment.

• Oil-based paint: good durability, which can maintain color and luster for a long time.

 

VI. Summary

 

As an environmentally friendly and efficient coating product, water-based paint is gradually replacing the traditional oil-based paint field and occupying an important position. Through this water-based paint knowledge training, we have an in-depth understanding of the definition, characteristics, basic composition, construction technology, construction equipment and differences from oil-based paint. This knowledge will help us better apply water-based paint in future applications, improve painting efficiency and quality, and reduce environmental pollution. Songying Chemical has entered the paint and coating market for 30 years and has accumulated profound experience and resources. From product research and development, allocation, dispersion, filtration, packaging, testing and other production processes, we can complete them independently. Over the years, we have invested a lot of money to hire high-tech and highly educated talents and formed a research and development team. The developed products have also passed the environmental management system, automobile industry quality management system and quality management system certification. The main products include special waterproof coatings, epoxy resins, silicone, graphene, acrylic acid, polyurethane, fluorocarbon, polysiloxane and other systems, providing single-component and two-component coating types. The products are widely used in high-end construction, new energy transportation, containers, bridges and ships and other important projects. At the same time, the company has multiple brands and supports O E M, O D M and other models. The annual production capacity of coatings reaches 10,000 tons, and the international market is mainly distributed in the Middle East, Europe, the United States, Southeast Asia and other regions. Facing customers from all walks of life, we provide U+ exclusive after-sales service and have cooperated with many partners for 23 years.
