Fluoro coating for internal maintenance of concrete stirring tank

Abstract

The invention discloses fluoro coating for internal maintenance of a concrete stirring tank and relates to the technical field of fluoro coating. The fluoro coating is prepared from, by weight, 25-30 parts of superfine Teflon powder, 10-15 parts of fluorocarbon resin, 10-15 parts of activated clay, 8-12 parts of polyamide resin, 5-9 parts of water-white rosin pentaerythritol ester, 5-9 parts of furfural residues, 4-7 parts of polybutylene terephthalate, 4-7 parts of glycerol ester of hydrogenated rosin, 3-6 parts of C5 petroleum resin, 3-6 parts of rubber powder, 3-6 parts of flexibilizers, 2-4 parts of pine needle meal, 2-4 parts of rape seed cakes, 1-2 parts of calamine powder, 0.5-1 part of zirconium oxide, 30-35 parts of butyl acetate and 25-30 parts of cyclohexanone. A coating layer formed through the fluoro coating has excellent corrosion resistance and abrasion resistance, and concrete is effectively prevented from corroding the inner wall of the stirring tank and adhering to the inner wall of the stirring tank, so that the situation that preparation of next batch of concrete is affected by the adherent concrete is avoided, and meanwhile, the service life of the stirring tank is prolonged.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fluorine coatings, in particular to a fluorine coating for internal maintenance of a concrete mixing tank. [0003] Background technique: [0004] Concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the base material, mixed with water in a certain proportion, and stirred. It is widely used in various constructions such as civil engineering. Existing concrete is usually realized by using equipment such as concrete mixers or mixing tanks according to different construction requirements and conditions. Since the concrete is easy to attach to the mixing tank, the tank needs to be rotated continuously, but a certain amount of concrete will still adhere to the tank wall; and the concrete is alkaline, so it will corrode the inner wall of the mixing tank, thus shortening the life of the mixing tank service life. In order to reduce the adhesion o...
