Inorganic nano composite anti-doodling resin and preparation method thereof

Abstract

The invention discloses an inorganic nano composite anti-doodling resin and a preparation method thereof. Silane-coupling-agent-modified inorganic nanoparticles, fluorine-containing acrylate monomer, alkyl acrylate monomer and hydroxyalkyl acrylate monomer are subjected to free-radical polymerization reaction to obtain the inorganic nano composite anti-doodling resin. The film formed by the inorganic nano composite anti-doodling resin has the advantages of excellent weather resistance, excellent scratch resistance, excellent chemical corrosion resistance, excellent ultraviolet resistance, excellent wear resistance, low surface energy, excellent pollution resistance and excellent anti-doodling performance, thereby implementing the long-term anti-doodling action. The invention relates to the field of an anti-doodling resin and a preparation method thereof.

Description

technical field

[0001] The invention relates to the field of anti-graffiti resin and its preparation method, in particular to an inorganic nanocomposite anti-graffiti resin and its preparation method. Background technique

[0002] Malicious graffiti is a pain for city managers. The cost of graffiti removal in various countries is huge. The UK spends 200 million pounds a year on graffiti removal, while the United States costs more than 20 billion pounds. The loss caused by malicious graffiti has attracted more and more attention. At present, the most effective anti-graffiti technology is the coating formed by anti-graffiti resin, which makes graffiti difficult or easy to remove. Giving the surface of the object a layer of low surface energy antifouling coating can effectively prevent the adhesion and pollution of graffiti, and even the pollution can be easily removed by simple wiping. The currently known compounds with the lowest surface energy are organic fluorines, which...
