Anti-fouling and anti-sticking sticker of special coating

Abstract

The invention discloses an anti-fouling and anti-sticking sticker of special coating. The anti-fouling and anti-sticking sticker of the special coating is mainly achieved through low surface energy, the surface energy of fluorocarbon resin is further lowered by modifying silicon of the fluorocarbon resin, by adding a special anti-sticking addition agent with the low molecular weight, the coating forms a layer of dense paint film with the low molecular weight and ultralow surface energy on the surface of a paint film through surface migration of the special addition agent in the film-forming process, thus excellent hydrophobicity and lipophobicity are achieved, and various adlets adopting paste, glue and an adhesive sticker as binding agents are difficult to stick or adhere unstably even ifbeing stuck reluctantly; scribbling prevention is achieved, that is, the low surface energy is required, and it is also required that the coating has good closure and the good solvent-resistant type;and in addition, the silicon-modified fluorocarbon resin containing an OH group is adopted and matched with anti-yellowing isocyanate at the room temperature, thus the effect that the paint film is denser and more resistant to water and a solvent is achieved, and after the coating film is stuck, the sticker can be removed through a detergent aqueous solution or a special cleaning agent containingan organic solvent conveniently and thoroughly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to antifouling and antisticking of special coatings. Background technique [0002] One of the unavoidable problems in city appearance and environmental governance is "urban psoriasis". There are a large number of small advertisements and graffiti posted on street light poles, utility poles, signal poles, distribution boxes, and garbage cans. It takes a lot of manpower, material resources, and Financial resources have a great negative impact on the city's appearance and environmental sanitation. In response to the above problems, some industries have developed an anti-adhesive paint. After the surface of the external wall and facilities is painted with the anti-adhesive paint, "small advertisements" such as stickers and pasted paper cannot be pasted, and marker pens, etc. are scribbled. The scribbled graffiti can be easily erased with cleaning agent without any damage to the surf...
