Water-based plastic coating and preparation method thereof

Abstract

The invention discloses a water-based plastic coating. The water-based plastic coating comprises the following components: a water-based resin emulsion, deionized water, a filler and additives. The invention further designs a preparation method of the water-based plastic coating, and the preparation method comprises the following steps: adding the filler into the water-based resin emulsion, adding an appropriate amount of deionized water, stirring, pouring into a sand mill for grinding, putting into a dispersing cylinder when the fineness is below 80mu m, adding the additives, sealing, stirring and detecting the viscosity for not less than 95s to prepare the water-based plastic coating. The water-based plastic coating has excellent water absorption, water retention, water suction and drainage and a good humidity adjusting effect, can be used for regulating the indoor relative humidity, and has the advantages of relatively high scrubbing resistance, water resistance and solvent resistance, corrosion resistance, alkali resistance, light resistance, weather resistance, good film-forming property, excellent color retention, wear resistance, corrosion resistance, controllable hardness, high performance-price ratio and the like, and the preparation method is simple, easy to operate without pollution, good in construction and safe to use.

Description

technical field [0001] The invention belongs to the field of industrial paint preparation, in particular to a water-based plastic paint and a preparation method thereof. Background technique [0002] Plastic is light in weight, easy to process and corrosion-resistant. Rich resources and other characteristics have widely replaced traditional materials such as metals. Wood, leather, etc., commonly appear in our daily life. However, when plastic products are molded and processed, they will have defects such as uneven color, monotonous color, mottled defects, etc., and are prone to problems such as aging and brittleness, scratches, stains, and static electricity. Coating can avoid the above-mentioned defects and problems. The research and development of plastic coatings has been widely concerned by paint workers. However, since plastics are low surface energy substances, their surface coating is much more difficult than that of steel, wood, buildings, etc. Efforts have become...

Problems solved by technology

Due to the requirements for environmental protection and resources, people have requested to limit the use of high VOC content and toxic coatings. The research and development of water-based plastic coatings in my country is relatively late.

Due to the nature of water, although plastic water-based coatings have many advantages, compared with traditional solvent-based coatings, there are still some problems. The first is that water has a high latent heat of evaporation and is easily affected by humidity, resulting in sagging and flashing pigments. Misorientation and other issues
