Description
Technical field
The present invention relates to a kind of PVC plastic and preparation method thereof, particularly relate to a kind of Modifying Character for PVC Plastic and preparation method thereof.
Background technology
Polrvinyl chloride, English abbreviation PVC (Polyvinylchloridepolymer=PVC molecular structure), is the thermoplastic resin being polymerized under initiator effect by vinyl chloride. It it is the homopolymer of vinyl chloride. Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin. PVC is the white powder of impalpable structure, and the degree of branching is less. Industrial PVC molecular weight is typically in 50,000-12 ten thousand scopes, has bigger polydispersity, the reduction of molecular weight with polymerisation temperature and increase; Without definite melting point, 80～85 DEG C start softening, and 130 DEG C become viscoelastic state, and 160～180 DEG C start to be changed into viscous state; There are good mechanical performance, about tensile strength 60MPa, impact strength 5～10kJ/m2; There are the dielectric properties of excellence. But the poor stability to light and heat, more than 100 DEG C or through long-time exposure in sunshine, will decompose and produce hydrogen chloride, and autocatalysis decomposes further, causing variable color, physical and mechanical properties also declines rapidly, must be added to stabilizer in actual applications to improve the stability to light and heat. PVC is very hard, and dissolubility is also very poor, can only be dissolved in the minority solvents such as Ketohexamethylene, dichloroethanes and oxolane, and organic and mineral acid, alkali, salt is all stable, and chemical stability reduces with the rising using temperature.
Common product: sheet material, tubing, sole, toy, door and window, wire outer skin, stationery, packing box etc.
Corvic industry belongs to basic type and energy intensive industry, is affected by demand and energy prices relatively big, is again basic chemical industry raw material simultaneously, therefore associates also closely with economic development. From the situation of 2012, owing to domestic PVC resin production capacity still constantly reduces, and downstream demand increases relatively slow, outlet obstructions in addition, import increases, therefore the domestic PVC resin enterprise entirety utilization of capacity is not high, the idle quantity of production capacity is relatively big, and the market price also remains that middle low level is hovered, and price fluctuation interval reduces, it addition, the listing of Corvic futures adds the uncertainty of Corvic market price fluctuations to a certain extent.Prospect a few years from now on, China's Corvic industry will be in a comparatively difficult integration period, will have the various factors development to China's Corvic in future.
