Problems solved by technology

The construction method of fluorocarbon baking varnish is to process the aluminum plate according to the engineering drawings, then spray fluorocarbon baking varnish, plasticize and switch at a high temperature of 200-235°C to form a film, stick a protective film, transport it to the construction site, and install it on the construction site. On the metal frame, this method is complicated and costly, which affects the application of fluorocarbon baking varnish

Abstract

The imitation metal fluorocarbon paint includes component A containing fluorocarbon resin (53%), metal pigment paste, wetting dispersing agent, cellulose acetate-butyrate, colour paste, antisettling sagging agent and solvent and component B containing hexamethylene diisocyanate tripolymer. Their mixing ratio is A:B=10-14:1, according to the above-mentioned mixing ratio, the imitation metal fluorocarbon paint can be made up. It possesses the following advantages: 1. it can be solidified and film-formed at normal temp.; 2. it can be directly spray-coated on the surface of external wall of cement building; 3. its construction is simple, its cost is 1 / 5 of that of baked aluminium curtain wall; and 4. said paint not only can be used for decorative protection of wall body but also can be used in the fields of steel and iron structure, wooden product and plastics.

Description

(1) Technical field: [0001] The invention is a metal imitation fluorocarbon paint. (two) background technology: [0002] On the exterior walls of high-rise buildings, metal aluminum curtain wall hanging panels are often used for decoration and protection to ensure an anti-aging service life of more than 20 years. In terms of weather resistance, such as ultraviolet radiation, wind erosion, chalking, cracking, and atmospheric corrosion resistance are very demanding. The only paint that can achieve this high weather resistance is fluorocarbon baking paint. The construction method of fluorocarbon baking varnish is to process the aluminum plate according to the engineering drawings, then spray fluorocarbon baking varnish, plasticize and switch at a high temperature of 200-235°C to form a film, stick a protective film, transport it to the construction site, and install it on the construction site. On the metal frame, this method is complicated and costly, which affects the appli...
