Embodiment Construction

[0047] The present invention is further illustrated below in conjunction with specific examples, but these examples are only for explaining the present invention, rather than limiting the scope of the present invention.

[0048] The FEVE fluororesin (hereinafter represented by F1-F4) in the embodiment is all self-made, and the resin composition is as follows:

[0049] F1, self-made, is made by copolymerization of chlorotrifluoroethylene, ethyl vinyl ether, Veova9 and hydroxyethyl acrylate, the fluorine content is 18%, the hydroxyl value is 41mgKOH / g, and the Tg is 55°C.

[0050] F2, self-made, is made by copolymerization of tetrafluoroethylene, vinyl acetate, Veova10, ethylene glycol allyl ether and crotonic acid. The fluorine content is 29.8%, the hydroxyl value is 30mgKOH / g, and the Tg is 70°C.

[0051] F3, self-made, copolymerized from chlorotrifluoroethylene, vinyl acetate, Veova9, Veova10, 4-hydroxybutyl vinyl ether, undecylenic acid, fluorine content 25%, hydroxyl value ...

Abstract

The invention discloses a fluorocarbon matte finishing paint curable at normal temperature. The fluorocarbon matte finishing paint comprises, by weight, a component A and a component B, wherein the component A comprises FEVE fluororesin, an anti-adhering agent, a dispersing agent, a delustering agent, a leveling agent, an antifoaming agent and a solvent, the component B comprises a curing agent, a drier and a solvent, wherein detailed proportions of the components and a preparation method for the paint are described in the specification. The fluorocarbon matte finishing paint has the advantages that 1, the paint has ultra-strong long-lasting corrosion resistance and aging resistance; 2, a film formed by the pain is compact, has good adhesion and allows water and steam to pass through in a long period of time; 3, the paint has the characteristics of long-term fingerprint resistance and contamination resistance; and 4, a protection construction method for metal-decorated buildings is simple, and the paint allows a coated part to be beautiful and presents stereoscopic sensation and decorous impression.

Description

technical field [0001] The invention relates to a finish paint and a preparation method thereof, in particular to a normal-temperature-cured fluorocarbon matte finish paint, which belongs to the field of metal decorative building protection. Background technique [0002] According to the statistics of relevant departments, nearly 50% of my country's cities have experienced severe or above pollution, and a thick layer of air pollution covers 15% of the country's regions. Based on this estimate, the annual economic loss due to pollution exceeds 200 billion yuan. These increasingly serious smog, oil fume, industrial waste gas, automobile exhaust, acid rain, etc. have brought surface pollution problems that greatly affect the aesthetics, functionality and durability of outdoor buildings, especially high-end metal building components. [0003] Metal decoration buildings such as high-end community copper doors, imitation copper doors and windows, fences, metal curtain walls and ot...
