Embodiment 1

[0065] 1. Preparation of mixed resin clear material: First, add 4-9% of polyvinyl chloride resin and 5-11% of perchlorovinyl resin to 50-65% of cyclohexanone to dissolve by weight percentage, then mix the two and stir evenly. Then add 5-10% of fluorine resin and 5-12% of acrylic resin, after fully stirring, add 5-9% of dibutyl ester, and after fully stirring and homogenization, it becomes the mixed resin clear material.

[0066] 2. A1 component preparation: mixed resin clear material 55-65%, Yingdan 2-10%, anti-settling agent 0.5-1.5%, iron oxide red 2-10%, extender pigment 1-4%, chlorinated paraffin 0.1 -2.0%, leveling agent 0.3-1.0%, anti-ultraviolet absorber 0.05-0.15%, xylene 20-30%, defoamer 0.05-0.15%. Calculate the above raw materials by weight percentage, stir and mix to homogenize.

[0067] 3. A2 component preparation: mixed resin clear material 55-65%, titanium dioxide 8-13%, chlorinated paraffin 0.1-2.0%, anti-settling agent 0.5-1.5%, leveling agent 0.3-1.0%, anti-ultra...

Embodiment 2

[0073] 1. Preparation of mixed resin clear material: First, add 6.6% of polyvinyl chloride resin and 8.2% of perchlorovinyl resin to 62.3% of cyclohexanone to dissolve by weight percentage, then mix the two, stir evenly, and then add 8.2% of fluororesin And acrylic resin 8.2%, after fully stirring, add 6.5% of dibutyl ester, and after fully stirring and homogenization, it becomes the mixed resin clear material.

[0074] 2. A1 component preparation: 60% of mixed resin clear material, 5% of Yingdan, 0.9% of anti-settling agent, 4% of iron oxide red, 3% of body pigment, 1% of chlorinated paraffin, 0.9% of leveling agent, anti-ultraviolet 0.1% absorbent, 25% xylene, 0.13% defoamer. Calculate the above-mentioned raw materials by weight percentage, stir and mix to homogeneity.

[0075] 3. A2 component: 60% mixed resin clear material, 11% titanium dioxide, 1% chlorinated paraffin, anti-settling agent 0.9%, leveling agent 0.9%, anti-ultraviolet absorber 0.1%, xylene 26%, defoaming Agent 0...

Abstract

The invention discloses a polyvinyl chloride fluoric ferrophosphorus coating, which consists of components A and B. Component A is 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 coating film thickness is 180 Mu m, and the service life of the coating can be more than 15 years under the heavy-duty anticorrosive condition. The coating can be widely applied in anticorrosion engineering of industrial architecture, petroleum, chemical engineering, medicine, process pipes, equipment, steel components, bridges, and shipbuilding, as well as protection of strong, medium and weak corrosive media on surfaces of indoor and outdoor steel structures and concrete. The coating has the characteristics of efficient corrosion prevention, high ratio of performance to price, high resistance to temperature and weatherability, excellent oil resistance, convenient construction, and long service life.

Description

Technical field [0001] The invention relates to the technical field of industrial anti-corrosion coatings, in particular to a two-component solvent-based polyvinyl chloride fluorine-containing fluorescein coating. technical background [0002] At present, among the anti-corrosion coatings used in the prior art, the coatings composed of polyvinyl chloride, perchloroethylene and high chlorinated polyethylene one-component resin as film-forming substances have thin film, brittle quality, poor adhesion, Disadvantages such as poor anti-corrosion performance and short service life. In practical applications, some products have been eliminated due to poor performance, such as polyvinyl chloride and perchloroethylene coatings. Some are only limited to use under moderate and weak corrosive conditions, and cannot be used in strong corrosive conditions, such as high-chlorinated polyethylene coatings. Summary of the invention [0003] The purpose of the present invention is to solve the pro...
