Vinyl resinThe raw materials come from petrochemical industry, span>Rich resources and low prices，At the same time, it has a series of advantages: such as weather resistance, corrosion resistance, water resistance, electrical insulation, mildew resistance, non-flammability, etc. Most vinyl resin paints are volatile paints and have the characteristics of self-drying. Therefore, its production proportion gradually increases in the total coating production.
Chlorine-vinegar copolymer resin coating
The molecular structure of polyvinyl chloride is regular, with inter-chain Strong association,High glass transition temperature and poor solubility. Copolymerize with vinyl acetate monomer,It increases the flexibility of the polymer and improves its solubility, while retaining the advantages of polyvinyl chloride such as non-flammability, corrosion resistance, toughness and wear resistance. Mainly used in anti-corrosion coatings in chemical plants and food packagingCoatings, paper coatings, fabric coatings, plastic product surface coatings, wood varnish, ship and marine equipment coatings, etc..
Vinylidene chloride copolymer resin coating
Polyvinylidene chloride has a symmetrical molecular structure and very good chemical resistance, but it is difficult to dissolve in organic solvents. Commonly used vinyl chloride or propyleneNitrileCopolymerize with it to make anti-corrosion paint. Chlorine bias copolymer resinCanWidely used in diet-related (such as drinking waterCabinet, foodproductPackaging container , beer barrels, etc.). vinylidene chloride-AcrylicNitrileThe gas and liquid permeability of the copolymer is extremely low,Suitable for formulating coatings for paper products and cellophane that require high air tightness. The most important use of this resin material is for the internal oil tank of large oil tankers that transport oil at seatankPaint.
Polyvinyl acetal resin coating
Polyvinyl acetal is the heaviest among polyvinyl alcohol derivativesTo workIndustrial products, in appropriate media (such as water, alcohol, organic or inorganic acids, etc.), polyvinyl alcohol and aldehydes are condensed Polyvinyl acetal resin can be produced fromatitToolsHas a variety of excellent properties,Such as high hardness, excellent electrical insulation, good cold resistance, and strong adhesionStrong, good transparency, etc., and the main raw materials can be obtained from petrochemical companiesQuantityPreparation. Therefore, it is widely used in coatings, synthetic fibers, and adhesives In the production of agents, safety glass interlayers and insulation materials, etc.
Chlorinated polyOlefinPaint
Chlorinated polyOlefinResins, including chlorinated polyethylene, chlorinated polypropylene, etc., is made from low molecular weight polymers that are by-products of petrochemical industry become. Due to their various excellent properties (chemical corrosion resistance, weather resistance, electrical insulation and extremely high initial light)Ze), can be used as a film-forming substance for coatings . Chlorinated polyeneHydrocarboncan be produced based on A series of paints for different uses. Such as exterior paint, chemical anticorrosive paint, ship paint and tropical conformal paint, etc.
Perchlorethylene coating
Polyvinyl chloride is further chlorinated to obtain perchlorethylene, which retains the polyethylene Vinyl chloride has excellent properties such as corrosion resistance, non-flammability, electrical insulation, and mildew resistance. It can be dissolved in many solvents into low-viscosity, high-concentration solutions, which is beneficial to the production of coatings. This type of coating has many excellent properties, but Not heat resistant and poor adhesion.
