Description
Technical field
The present invention relates to a kind of cable jacket material, the manufacturer of the PP cable jacket materials of more particularly to a kind of termite-resistant rodent-resistant
Method.
Background technology
Polypropylene English entitled Polypropylene, abbreviation PP, are commonly called as polypropylene (PP), are made using Ziegler-Natta catalyst
Propylene catalytic polymerization and obtain, it is a kind of thermoplastic resin.PP is a kind of conjunction for starting a large amount of productions nineteen fifties
Resin, it is the copolymer of Noblen or propylene and alhpa olefin (ethene, butene-1, hexene -1), and its molecule is linear
Structure, density are 0.89～0.91g/cm3, also lower than the density of low density polyethylene (LDPE).As PP has relative hardness height, proportion
Little, tensile strength is high, the transparency is good, anti-stress cracking and good, the resistance to heat deflection temperature of chemical-resistance are high and with fabulous note
Plasticity energy, can arbitrarily stretch and orient, can with other materials blending and modifying the advantages of, therefore PP ranges of application constantly expand,
In five big resins for universal use, demand growth is fastest, gradually replace iron and steel, timber, paper, Merlon, ABS, PS, nylon,
Other synthetic materials such as polyester.
At present, China PP products yield is only below PE products more than PVC product and occupies second, accounts for plastic products total
The 25% of yield, mainly for the production of fibrage, injection-molded item, film, sheet material, sheet material, cable and protective cover material, blow-molded article
And tubing etc..PP cable jacket materials using when often run into ant class, biting for muroid and cause security incident, for this
Individual problem, existing solution are usually to add termite-resistant rodent-resistant agent toward PP cable jacket materials, but protection against rodents when directly adding
Compatibility between anti-termite agent and PP is bad, it is difficult to be dispersed in PP, so that ant-proof mouse-proof effect is had a greatly reduced quality.
Publication No. CN104744807A, publication date are 2015.07.01, apply for artificial Shanghai Kaibo Special Cable Material Factory
The Chinese patent application of Co., Ltd discloses " a kind of soft polypropylene cable jacket material ", including the component of following weight portion：
