Problems solved by technology

[0004] Existing anti-graffiti and anti-sticking coatings have problems in varying degrees, either the anti-sticking properties are not good, or the anti-graffiti properties are not good, or the scratch resistance is not good, or the aging resistance is not good, especially to meet the anti-graffiti and anti-sticking properties at the same time. The technical solution for pasting these two important properties remains to be further studied

Abstract

The invention provides an anti-graffiti and anti-sticking material and a preparation method and application thereof, the anti-graffiti and anti-sticking material comprises a component A and a component B. The component A is prepared from the following raw materials in percentage by weight: 15-20% of an amino silane coupling agent, 70-80% of hydroxyl silicone oil and 5-10% of polydimethylsiloxane; the component B is prepared from the following raw materials in percentage by weight: 62 to 66 percent of siloxane-based organic silicon resin 1, 25 to 27 percent of siloxane-based organic silicon resin 2, 2 to 3 percent of light stabilizer and 5 to 10 percent of isopropyl alcohol; the weight ratio of the component A to the component B is (1: 4)-(1: 6). By adding the siloxane-based organic silicon resin, the hydroxyl silicone oil, the polydimethylsiloxane and the light stabilizer, the prepared anti-graffiti and anti-sticking material simultaneously has the properties of doodling resistance, sticking resistance, scratch resistance, solvent resistance and weather aging resistance, and is suitable for the fields of outdoor facility protection or industrial product protection and the like.

Description

technical field [0001] The invention belongs to the technical field of protective functional materials for outdoor facilities, and relates to an anti-graffiti and anti-sticking material, a preparation method and application thereof. Background technique [0002] Random postings and graffiti on the streets and alleys of the city, residential buildings and courtyards, public facilities and other illegal small advertisements have seriously damaged the city's appearance and environment, becoming a major public nuisance and persistent disease that affects the city's image, known as "psoriasis" on the streets. Practice has proved that there is a very effective solution, which is to paint anti-graffiti and anti-sticking materials on streets, alleys, residential buildings, and public facilities, so that graffiti can be easily erased and small advertisements cannot be pasted at all. Fundamentally solved the urban "psoriasis" this stubborn disease. [0003] CN111417692A discloses a c...
