Chlorosulfonated polyethylene (C8M for short) anticorrosive coating is a newly developed special anticorrosive coating with excellent performance (foreign name: Haibolong). It is mainly composed of CSM, improved resin, vulcanizer, accelerator, filler, organic solvent, etc. It is obtained by chlorosulfonation reaction of polyethylene. It has polar group chlorine and chlorosulfonic acid group and its molecular saturation, so it has excellent chemical, physical and mechanical properties such as anti-oxidation, resistance to natural aging, acid and alkali resistance, and resistance to chemical media. This coating is a multifunctional comprehensive anticorrosive coating, its performance is better than epoxy, epoxy asphalt, perchloroethylene, chlorinated rubber, polyurethane and other anticorrosive coatings, the service life is 1-3 times longer than the commonly used perchloroethylene, polyurethane, etc., the anticorrosion cost can be saved by 40 to 60%, it has excellent corrosion resistance to strong acid, strong alkali and inorganic salt media, and has the characteristics of water resistance, oil resistance, heat resistance, cold resistance and resistance to chloride ion radiation; and it is also suitable for gas phase and liquid phase corrosion protection, creating convenient conditions for design and construction. Various technical performance indicators are at the domestic advanced level. This coating is the latest product in contemporary anti-corrosion coatings, and it has a long service life and is cheap. It is widely used in anti-corrosion projects such as walls, steel structures and equipment and facilities of chemical companies in the petroleum, chemical, metallurgical, light industry, textile, printing and dyeing industries. According to preliminary statistics, the annual consumption in each province is more than 100 tons, and the market prospect is very broad. Main production equipment: reactor, colloid mill, main raw materials: chlorosulfonated polyethylene; designed annual output of 300 tons, equipment investment of 30,000 yuan, ordinary factory building of 200 square meters; comprehensive cost per ton is 7,100 yuan, ex-factory price is 12,100 yuan; annual output value is 3.64 million yuan, annual profit is 1.5 million yuan; environmental protection without three wastes; technology transfer fees, training fees, and consulting fees total 45,000 yuan. After the technology transfer contract is signed, a full set of technical documents and materials such as technical formula, production process diagram, equipment and raw material list will be handed over to the production party, and technical personnel will be trained for the factory. Guide the purchase of equipment and raw materials, etc., to ensure that the factory produces qualified products.
