Description
Technical field
The present invention relates to a kind of plastics more particularly to a kind of high-strength PVC plastics.
Background technology
Plastics (English name：Plastic), refer to using the synthetic resin of high molecular weight as key component, addition suitably adds
Add agent, such as plasticizer, stabilizer, fire retardant, lubricant, colorant, processed molding plasticity (flexibility) material or solid
Change the rigid material being cross-linked to form.Plastics are the products in 20th century, and since it is by exploitation, the purposes of various aspects is increasingly wide
It is general.
Synthetic resin is the main ingredient of plastics, and content in the plastic is generally in 40-100%.Since content is big,
And the property of resin usually determines the property of plastics, so people often regard resin as the synonym of plastics.Such as
Corvic lumps together with igelite, phenolic resin and phenoplasts.In fact resin and plastics be two not
Same concept.Resin is a kind of unprocessed original polymer, it is applied not only to manufacture plastics, but also is coating, adhesive
And the raw material of synthetic fibers.And plastics are other than a few part is containing 100% resin, most of plastics, in addition to master
It wants outside component resin, it is also necessary to add in other substances.
Polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride) are vinyl chloride monomer (vinyl chloride
Monomer, abbreviation VCM) in initiators such as peroxide, azo-compounds；Or Raolical polymerizable is pressed under light, heat effect
The polymer that mechanism is polymerized.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.
The present invention provides a kind of high-strength PVC plastics, and intensity is high, and with excellent scratch resistant performance.
Invention content
For above-mentioned deficiency in the prior art, the first technical problem to be solved by the present invention is to provide a kind of high
Intensity PVC plastic.
