Description
Technical field
The application belongs to PVC material field, particularly relates to a kind of PVC elastomer and preparation method thereof.
Background technology
Polyvinyl chloride, English abbreviation PVC(Polyvinyl chloride), it is that VCM (vinyl chloride monomer is called for short VCM) is at the initiator such as peroxide, azo-compound；Or the polymer being polymerized by mechanism of free-radical polymerization under light, heat effect.Ryuron and vinyl chloride copolymer system referred to as vinyl chloride resin.
Industrial PVC molecular weight, typically in the range of 50,000～110,000, has bigger polydispersity, the reduction of molecular weight with polymerisation temperature and increase；Without definite melting point, 80～85 DEG C start to soften, and 130 DEG C become viscoelastic state, and 160～180 DEG C start to be changed into viscous state；There is preferable mechanical performance, about tensile strength 60MPa, impact strength 5～10kJ/m2；There are the dielectric properties of excellence.
PVC was once the general-purpose plastics that yield is maximum in the world, and application is widely.All it is widely used at aspects such as construction material, industrial product, commodity, flooring laminate, floor tile, artificial leather, tubing, electric wire, packaging film, bottle, expanded material, encapsulant, fibers.
PVC had been found twice in 19th century, be once Henri Victor Regnault in 1835, another time is Eugen Baumann to be found in 1872.In twice chance, this polymer appears in the beaker being placed on the vinyl chloride under sunshine, becomes white solid.20 beginnings of the century, the chemist Fritz Klatte of Russianize scholar Ivan Ostromislensky and Griesheim-Elektron company of Germany attempts being used for PVC commercial use simultaneously, but it is difficult to how to process this hard, sometimes fragility polymer..
Widely, but at middle nineteen seventies, people recognize that in Corvic and goods, the monomeric vinyl chloride (VCM) of residual is a kind of serious carcinogen, undoubtedly in the development that to a certain degree can affect polyvinyl chloride to igelite product application.But people have successfully passed through the VCM of the approach reduction residuals such as automobile, make VCM in Corvic can be less than 10ppm by content, reach sanitation-grade resin requirement, expand the range of application of polyvinyl chloride.The VCM content in resin even can be made less than 5ppm, and after processing, the VCM of residual is few.The most harmless to human body, can be used as food drug package and toy for children etc..
According to the difference of range of application, PVC can be divided into: universal polyvinyl chloride resin, PVC with high, crosslinked PVC resin.Universal polyvinyl chloride resin is to be polymerized under the effect of initiator by VCM to be formed；PVC with high refers to add in polymerization of vinyl choride monomer system the resin that chain extender is polymerized；Crosslinked PVC resin is to add the resin that the crosslinking agent containing diene and polyenoid is polymerized in polymerization of vinyl choride monomer system.
Polyvinyl chloride can be substituted reaction by ethene, chlorine and catalyst and make.Due to its fireproofing and heat resistant effect, polyvinyl chloride is widely used in all trades and professions product of all kinds: wire outer skin, optical cable coating, footwear, handbag, bag, jewelry, signboard and billboard, building decoration articles for use, furniture, ornament, roller, trunnion, toy (as horse-vaulting is jumped by famous Italy " Rody "), door curtain, rolling door, medical assistance articles for use, gloves, the tin foil of some food, some fashionable dress etc..And popularizing along with humanity concept, and the composition of novel harmonious society, a kind of intensity PVC elastomer high, impact-resistant of design and preparation method thereof is very important.
Current China modified plastics year aggregate demand is about about 5,000,000 tons, accounts for about the 10% of whole plastics overall consumption, and its ratio is well below the average level in the world.China's plastics consumption figure per capita there is also the biggest gap compared with World Developed Countries.Wanting to realize the fast steady development of China's modified plastic industry, innovative technology is the key point of future development.
Chemical industry analyst think, the current overall development level of China's modified plastic industry is not the highest, the production scale of enterprise inside the circle is the least, the primary product that product market goes out are many, middle rank product quality is not sufficiently stable, the feature that high-grade products lack, far from the needs meeting China's current social economic development.As an important component part in new chemical materials field, modified plastics has been classified as one of sciemtifec and technical sphere of giving priority to by country.Release successively modified plastic industry will be promoted further to develop from the every policy of China.Automobile and household electric appliances are the focuses of modified plastics development, and both accountings are about more than 50%.
