Problems solved by technology

This kind of paint has low solid content, only about 17%; the paint film is thin, and the thickness of each coat is about 18 μm; the construction performance is poor, and it is easy to pull back and forth; the leveling property is poor, the decorative performance is poor, and the construction cost is high.
In addition, due to the low solid content and high volatile solvent content in the coating, the environmental pollution is relatively large.

Abstract

The invention discloses a polyvinyl chloride fluoric ferrophosphorus coating, which consists of components A and B. Component A can be divided into A1 and A2. A1 is a polyvinyl chloride fluoric ferrophosphorus primer; and A2 is a polyvinyl chloride fluoric ferrophosphorus finish coat. Component B is a polyurethane curing agent. Before use, a primer is prepared with A1 and B in the ratio of 12 to 1 by weight; and a finish coat is prepared with A2 and B in the ratio of 12 to 1 by weight. The temperature for the coating to be used for a long time is 120 DEG C; the coating contains 30 to 50 percent of solid; the coating film thickness is 30 Mu m per round to 40 Mu m per round, and the construction time is reduced. As fluoric ferrophosphor is added, the corrosion resistance is significantly improved. In addition, the construction cost is reduced, and the construction cycle is shortened.

Description

technical field [0001] The invention relates to the technical field of industrial anticorrosion coatings, in particular to a two-component solvent-based polyvinyl chloride fluoride coating. technical background [0002] In the prior art of industrial anticorrosion coatings, the coatings of this variety produced and supplied on the market are all coatings with a single polyvinyl chloride resin as the main film-forming substance. The solid content of this kind of coating is only about 17%; the paint film is thin, and the thickness of each coating is about 18 μm; the construction performance is poor, and it is easy to brush back and forth; the leveling property is poor, the decorative performance is poor, and the construction cost is high. In addition, due to the low solid content and high volatile solvent content in the coating, the environmental pollution is relatively large. Contents of the invention [0003] The object of the present invention is to solve the problems ex...
