Abstract
The present invention belongs to the field of cable materials, and particularly relates to a flame-retardant stripping-type cable. The flame-retardant stripping-type cable comprises a conductor cable core, the conductor cable core is wrapped in an insulating layer, a talcum powder layer is arranged outside the insulating layer and wrapped in a sheath layer, and the insulating layer is wrapped in the talcum powder layer in an attaching mode. The sheath layer is prepared from, by weight, 100 parts of PVC resin, 0.1 part to 0.4 part of toughening agents, 30 parts to 40 parts of plasticizers, 1 part to 2 parts of antioxygen, 1 part to 2 parts of heat stabilizers and 15 parts to 20 parts of filling agents. The cable has excellent mechanical and physical properties, and the product meets the environmental protection requirement; meanwhile, the talcum powder layer is arranged between the insulating layer and the sheath layer of the cable, and therefore the sheath layer can be stripped easily, and recycling time is saved and recycling cost is reduced when the cable is recycled.
Description
Technical field
The invention belongs to cable material field, be specifically related to a kind of fire-retardant exfoliated cable of easy recovery.
Background technology
In modern society, the figure of the electric wire that is seen everywhere, cotton covered wire, the broadband access line used as family, hotel; Power cable, aerial cable etc. that power department lays, electric wire occupies very important status in national economy and social activities.And along with economic fast development, electric wire, cable industry have become the second largest industry of China.Growing along with what live, the replacement and obsoleteness of various electric power systems and electrical equipment, annual all by cable waste lines a large amount of generation, cable waste line chief component cupric, aluminium, plastics, rubber etc., all have high recycling and be worth.If a large amount of discarded cables can not well be processed, not only can cause the huge waste of resource, and meeting severe contamination people's living environment.Conventionally, the composition of cable from inside to outside, comprises conductor thread core, and conductor thread core is coated with insulating barrier, and insulating barrier is coated with restrictive coating.Cable, in the time reclaiming, need to reclaim its conductive layer and the each self-separation of non-conductive layer, and the non-conductive layer of cable is divided into again insulating barrier and restrictive coating, and existing cable is to be difficult for insulating barrier and restrictive coating to separate.For this reason, there is human hair to understand and be exclusively used in the treatment facility that electric wire reclaims, as Granted publication number provides a kind of cable waste line wire stripping recycling equipment for the utility model patent of CN202363822U, but, what this equipment was absorbed in is the recovery of various shape cables, is not special in being difficult for peeling off the insulating barrier of recycling and separating of restrictive coating.
Summary of the invention
The problem existing for solving above-mentioned prior art, the present invention aims to provide a kind of fire-retardant exfoliated cable of easy recovery.
Particularly, inventor provides following technical scheme:
A kind of fire-retardant exfoliated cable, its composition comprises conductor thread core, and conductor thread core is surrounded by insulating barrier outward, and insulating barrier is provided with talcum powder layer outward, and the outsourcing of talcum bisque has restrictive coating, and wherein, described talcum bisque is for to be coated on outside insulating barrier to attach mode; Described restrictive coating is prepared by following weight parts raw material: 100 parts of polyvinyl chloride resins, flexibilizer 0.1-0.4 part, plasticizer 30-40 part, antioxidant 1-2 part, heat stabilizer 1-2 part, filler 15-20 part.
There is the shortcoming that is difficult for peeling off in the restrictive coating for existing cable, the present invention is provided with a talcum bisque between insulating barrier and restrictive coating, and a kind of cable with peel ply can be provided.Simultaneously, the deficiencies such as the pliability, the shock resistance that exist for existing PVC sheath are not good, the present invention is taking polyvinyl chloride resin as base material, be equipped with appropriate flexibilizer and strengthen its intensity, and add other compounding ingredients such as plasticizer, antioxidant, heat stabilizer, filler of reasonable coordination, prepare weather-proof, fire-retardant, special soft PVC cable jacket material.Fill a prescription its mechanical and physical performance of product of preparation of the present invention detects and meets GB/T8815-2008 standard, has practicality widely, and when cable reclaims simultaneously, insulating barrier and restrictive coating are easily peeled off, and have greatly improved recovery operation efficiency.
As preferably, in the present invention, described flexibilizer is flexibilizer A-608.
As preferably, in the present invention, described plasticizer is the mixed ester of trimellitic acid 810 esters and tri trimellitate ester in the last of the ten Heavenly stems.
As preferably, in the present invention, described antioxidant is the compound of 4,4 '-thiobis (being 2-methyl-6-tert-butylphenol) and octylated diphenylamine and antioxidant BLE (being diphenylamines-condensation of acetone thing).
As preferably, in the present invention, described heat stabilizer is barium zinc composite stabilizer, model TY960.
As preferably, in the present invention, described filler is calcene, and granularity is at 1000-1500 order.
Compared with prior art, the present invention also has the following advantages:
Cable provided by the invention, possesses good mechanical and physical performance, and meanwhile, product of the present invention meets environmental requirement.In addition, product preparation method of the present invention to extrude cable craft identical with common cable expressing technique, practicality is general, promotes easily.
Cable of the present invention, is provided with talcum bisque between its insulating barrier and restrictive coating, can reduce the frictional force between restrictive coating and insulating barrier, make restrictive coating be easy to peel off, take out interior metal conductor wire, can realize while reclaiming cable, save recovery time and reduce cost recovery; Meanwhile, talcum powder is a kind of magnesium silicate mineral, and its hardness is little and fusing point is high, and electricity and heat are had to good insulating properties, and when the restrictive coating burning of outside makes, talcum bisque can further be avoided inner conductive line catching fire and cause larger harm.
