Anti-graffito waterborne paint for anti-theft door and preparation method of same

Abstract

The invention relates to the technical field of waterborne paints, especially relates to anti-theft door waterborne paint, and particularly discloses an anti-graffito waterborne paint for an anti-theft door and a preparation method of same. The waterborne paint is prepared by mixing an aqueous resin system with additives, wherein the aqueous resin system includes: a hydroxyl acrylic acid aqueous dispersion, entirely-methylated amino resin, and a polydimethylsiloxane emulsion containing a hydroxyl functional group. The waterborne paint is low in content of VOCs and is lowered in odor, can avoid air environment pollution and has low influence on human body and is more safe and environment-friendly. When the paint forms a film, the film has good adhesive force with a base material and is good in decorative performance, has excellent fullness degree and glossiness, is excellent in anti-graffito performance and is easy to scrub.

Description

Technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based coating for anti-theft doors. Background technique [0002] In our country, anti-theft doors comply with national standards, and have higher requirements in terms of materials and safety than those of general enterprise-standard protective doors and steel doors. As people's consumer needs change, more functions have been proposed for anti-theft doors. Performance requirements, such as paint film decoration performance, safety and environmental protection performance, anti-graffiti performance, etc. [0003] At present, most of the coatings for anti-theft doors in my country are mainly solvent-based coatings or powder coatings, and there are very few water-based coatings for anti-theft doors. The above coatings for anti-theft doors mainly have the following technical defects: [0004] 1. Solvent-based coatings contain a high content of volatile organic compound...

AI Technical Summary

Problems solved by technology

[0004] 1. Solvent-based coatings contain a high content of volatile organic compounds (VOC) and cause serious air pollution, which has a huge impact on human health, and there are fire hazards during storage and use;

[0005] 2. After the powder coating is formed into a paint film, there are generally problems such as poor gloss, low fullness, and low transparency;

[0006] 3. The existing water-based paint products for anti-theft doors have very high VOC. Generally, water-soluble acrylic resin amino baking paint is used, and its VOC is as high as 300g / L or more, and the smell is also very strong;

[0007] 4. Compared with solvent-based products, the gloss and fullness of the existing anti-theft door water-based paint products still have a certain gap compared with solvent-based products, resulting in poor decorative effects;

[0008] 5. The existing anti-theft door coatings do not consider the anti-graffiti functionality, especially the water-based anti-graffiti coating for anti-theft doors is still blank
