Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a kind of anti-fingerprint and anti-pollution environmental protection coating, which does not use fluorinated materials; firstly, polydimethylsiloxane is used to treat polyacrylate Modification, the surface of the prepared substrate has good hydrophobicity and good weather resistance. After mixing and cross-linking it with trimethylolpropane tris[3-(2-methylaziridinyl)propionate], the obtained The surface cross-linking density of the paint coating is large, the chemical shielding ability and the acid-base solution have good resistance, and has a strong self-repair ability to chemical and physical damage; the present invention first uses aloe vera extract as a biosurfactant Prepare strontium titanate nanoparticles, and then coat nano-titanium dioxide on its surface; the surface coating of nano-titanium dioxide reduces the surface defects of strontium titanate nanoparticles; and the active groups on the surface of nano-titanium oxide can interact with the active groups in the coating matrix. The group undergoes a cross-linking reaction, thereby improving the mechanical properties of the coating

Abstract

The invention discloses an anti-fingerprint and anti-pollution environment-friendly coating, which takes polydimethylsiloxane modified polyacrylate as a matrix, trimethylolpropane tri[3-(2-methylaziridinyl) propionate] as a cross-linking agent, and a dysprosium-doped nano titanium oxide / nano strontium titanate core-shell material as a reinforcing filler. The environment-friendly coating further comprises a dispersing agent, a leveling agent and deionized water. The invention further discloses a preparation method of the anti-fingerprint and anti-pollution environment-friendly coating. The prepared environment-friendly coating is good in stability, excellent in antifouling and anti-fingerprint performance, easy to prepare, low in cost, economical and environmentally friendly.

Description

Technical field: [0001] The invention relates to the field of coating preparation, in particular to an anti-fingerprint and anti-pollution environmental protection coating and a preparation method thereof. Background technique: [0002] The development of the economy has led to the growth of consumption of consumer goods, and products that used to be expensive, such as mobile phones and home appliances, have entered more and more families. However, during use, a large amount of dust, dirt and fingerprints will adhere to the surface of these products, and it is difficult to wipe clean, which seriously affects the appearance and service life of the products. So the problem that needs to be solved at present is how to make the surface of the product antifouling and free from fingerprints. [0003] In the 1980s, people began to look for substances with similar optical properties to human fingerprints, and pre-coated them on the surface of steel plates, so that even if fingerpri...
