Background technique
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.
Industrial PVC molecular weight generally in 50,000~110,000 ranges, have biggish polydispersity, molecular weight with
The reduction of polymerization 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 are opened
Beginning is changed into viscous state；There are preferable mechanical performance, tensile strength 60MPa or so, 5~10kJ/m2 of impact strength；Have excellent
Dielectric properties.PVC was once the maximum general-purpose plastics of yield in the world, very widely used.In construction material, industrial product, day
The side such as articles, flooring laminate, floor tile, artificial leather, tubing, wire and cable, packaging film, bottle, foamed material, sealing material, fiber
Face is widely used.
However due to its higher cost in presently used polyvinyl chloride again, it is necessary to which addition can be effectively reduced cost and can
The filler of reinforcement is modified it, but the usual density of filler of its addition is higher, so as to cause finally obtained PVC cable

Toughened cold-resistant special resin, the positive butyl- hydroxyl esters of this kind of resin category ethylene-acrylic acid, the addition of this resin increase PVC's
Toughness, while the problem of keep good mechanical performance again, effectively compensate for polyvinyl chloride resin black brittleness, effectively improve
The low-temperature catalyzed performance of PVC.And processing technology is simple, without doing big change to existing equipment, does not increase processing cost,
Market application prospect is wide.But there is also biggish defects, such as in its polyvinyl chloride resin the biggish filler of density in occupation of
Biggish specific gravity causes the final densities of finally obtained CABLE MATERIALS larger, ultimately increases the investment of cable producer, reduces
The synthesized competitiveness of product.
Summary of the invention
