Water-based coatings manufacturing methods

1. Introduction

With the continuous improvement of people's awareness of environmental protection, water-based coatings have gradually become the mainstream products in the coatings market. Waterborne coatings are widely used in construction, furniture, automobiles, ships and other fields because of their environmental protection, safety and easy cleaning. This paper will introduce the manufacturing method of water-based coatings in detail, aiming to promote the application and development of water-based coatings in the field of chemical production raw materials.

2. water-based paint profile

water-based paint is water as a solvent or dispersion medium paint, mainly including water soluble paint, water reducible paint and water dispersible paint and other types. Water-based coatings have the characteristics of low pollution, low toxicity, non-flammable and non-explosive, and have become the preferred coatings under the current environmental protection policy.

3. water-based coating manufacturing method

1. ingredients

first, according to the coating performance requirements, select the appropriate resin, pigment, filler, additives and other raw materials. Pay attention to ensure that the quality of raw materials is stable, so as not to affect the performance of the coating.

2. dispersion

the pigment, filler and other solid powder into the high-speed dispersing machine, add the appropriate amount of water, high-speed dispersion. The stirring speed and time should be controlled during the dispersion process to ensure that the powder is fully dispersed and to avoid excessive dispersion leading to particle breakage.

3. grinding

after dispersion of the slurry, the need for further grinding to improve the fineness. Grinding is carried out by equipment such as a sand mill or a three-roll machine, and the grinding time and fineness are adjusted according to the performance requirements of the coating.

4. paint mixing

the slurry after grinding and resin, additives and other raw materials mixed, stirring evenly. The proportion and addition sequence of each component should be controlled during the paint mixing process to ensure stable coating performance.

5. Filter

After the paint mixing is completed, use filter equipment to remove impurities and particles in the paint to ensure the quality of the paint.

6. Packaging

The filtered coating is packed into a clean and dry packaging barrel and sealed for preservation. Note that the label identification is clear for subsequent use and management.
Precautions for
4.

1. Strictly control the quality of raw materials to ensure stable coating performance.
2. Dispersion and grinding process need to control the stirring speed and time, to avoid excessive dispersion or grinding.
3. Paint mixing process should pay attention to the proportion of each component and the order of addition, so as not to affect the coating performance.
4. The filter equipment needs to be cleaned and replaced regularly to maintain the filtering effect.
5. The packaging barrel should be clean and dry to avoid contamination of the coating.

5. conclusion

waterborne coating as an environmentally friendly coating, its manufacturing method needs to strictly control the operating conditions of each process and the quality of raw materials. Through the manufacturing method introduced in this paper, water-based coatings with stable performance and excellent quality can be produced, which provides more choices for the field of chemical production raw materials. At the same time, with the continuous progress and development of water-based coating technology, its application field will be further expanded and make greater contributions to environmental protection.
