Curing fluorine containing paint in normal temperature with quadric-polymerization

Abstract

The invention discloses normal temperature curing coating containing fluorine prepared through a quaternary-copolymerization method, and a preparation method thereof. The invention relates to a normal temperature curing coating containing fluorine prepared through a quaternary-copolymerization method, and a production method thereof. Currently, CTFE is commonly applied to prepare coatings, and the prepared products have poor stability and are easy to be crystallized. The components of the product comprise: TFE, fatty acid vinyl ester, aliphatic enol and aliphatic gadoleic acid, wherein, the solid accounts for 60 to 70 weight portions, the hydroxyl value is 40mgkoH / g to 75mgkoH / g, the acid value is 8mgkoH / g to 15mgkoH / g, after 4 is applied, the viscosity in a cup is 45s to 54s, and the proportion is 1.10 to 1.25; the ratio of the weight portions of the TFE, fatty acid vinyl ester, aliphatic enol and aliphatic gadoleic acid in the polymer is as follows: 35 to 45:25 to 40:12 to 18:2 to 3, and the chain-like structure is as follows: the normal alkyl of R1 equal to C1 to C3; R2 equal to (CH)n, n equal to 1 to 6; R3(CH2)n, n equal to 1 to 10. The invention is applied in indoor decoration and other fields.

Description

Technical field: [0001] The invention relates to a room temperature curing fluorine-containing paint prepared by a four-element copolymerization method and a preparation method thereof. Background technique: [0002] With the progress of society and the continuous improvement of people's living standards, people's requirements for the home environment have gradually increased. The history of using lime to paint walls in the past has passed. Paint is a necessary material for everyone to decorate their homes, but the modern paint Some shortcomings have also been exposed thereupon. Chlorotrifluoroethylene is widely used to make coatings. The products manufactured by this method have poor stability and are easy to crystallize. Therefore, there is an urgent need in the market for the birth of products that can overcome these shortcomings. Invention content: [0003] The present invention uses tetrafluorochloroethylene instead of trifluorochloroethylene, and the bond energy of ...
