Problems solved by technology

Thirdly, one of the packaging components (curing agent) of the two-component chlorosulfonated polyethylene coating contains toxic and harmful heavy metal substances such as lead that cause the vulcanization reaction of the chlorosulfonated polyethylene resin, so that it can be used during preparation and use. There are certain security risks
Fourth, the existing single-component chlorosulfonated polyethylene coatings contain a vulcanization accelerator in the composition, and some have to prepare the vulcanization accelerator into a potential curing agent, which requires a heating polymerization process, which not only consumes a lot of energy, but also It also affects the storage stability of the paint

Abstract

The invention discloses single-component chlorosulfonated polyethylene anticorrosive paint and a preparation method thereof. The invention also comprises chlorosulfonated polyethylene resin liquid containing CSM-30 chlorosulfonated polyethylene resin and toluene. The prepared single-component chlorosulfonated polyethylene anticorrosive paint is convenient for construction, not only can be sprayed, but also can be coated, and has the advantages of convenient and simple use and quick paint film drying, wherein the surface drying time is not longer than 15 minutes, and the hard drying time is not longer than 4 hours; and the storage period of the paint at room temperature reaches longer than one year, and the anticorrosive property exceeds the index requirement of HG / T2661-1995 chlorosulfonated polyethylene anticorrosive paint (double-component) of the national industrial standard, thus the single-component chlorosulfonated polyethylene anticorrosive paint of the invention has better property compared with the traditional single-component chlorosulfonated polyethylene paint.

Description

Technical field [0001] The invention belongs to the field of paint preparation technology, and specifically relates to a formulation and preparation process of a one-component chlorosulfonated polyethylene anticorrosive paint. Background technique [0002] Chlorosulfonated polyethylene coatings are widely used in the protective coating of metal components and cement components due to their unique anti-corrosion properties. According to the prior art, firstly, the chlorosulfonated polyethylene coatings mainly appear in the form of two components, the A and B components are produced separately, and there are many production processes; when used, the A and B components are mixed evenly in a certain ratio Paint again. Second, in the preparation process of the chlorosulfonated polyethylene coating, the chlorosulfonated resin undergoes a plasticizing process, which releases toxic gases such as low molecular weight chlorides. Thirdly, one of the packaging components (curing agent) of ...
