PVC cable sheath material and preparation method thereof

Abstract

The invention discloses a PVC cable sheath material which is prepared from the following raw materials in parts by weight: 50-60 parts of PVC resin, 5-10 parts of natural rubber, 5-10 parts of butadiene rubber, 5-10 parts of polyethylene, 1-4 parts of fumed silica, 1-2 parts of glass fiber, 2-5 parts of graphene, 1.5-3 parts of anti-impact modifier, 5-10 parts of nano titanium dioxide powder, 1-4 parts of thermal stabilizer, 4-8 parts of plasticizer, 4-6 parts of accelerator, 2-5 parts of barium oxide, 3-5 parts of coupling agent, 4-8 parts of calcium oxide, 5-15 parts of perlite, 5-10 parts of lubricant, 3-6 parts of diammonium phosphate and 3-6 parts of zinc borate. According to the cable material disclosed by the invention, PVC resin is adopted as the main ingredient which is accompanied by other accessories; the cable sheath material does not contain such heavy metals harmful to human and environment as lead, cadmium, hexavalent chromium and mercury, meets the standard requirements on environmental protection and is safe and environmentally friendly and thus has high wear resistance and mechanical processing property and is convenient and easy to cut; moreover, the diamagnetic property, the waterproof property, the high-temperature resistance and the chemical corrosion resistance are improved over common cable material; the biodegradation cycle is short, the production cost is low, the economic value is high, and the prospect is very broad.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a PVC cable sheath material and a preparation method thereof. Background technique [0002] PVC cable material is based on polyvinyl chloride, adding stabilizers, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate, etc. Plasticizers and inorganic fillers such as calcium carbonate, additives such as additives and lubricants, particles prepared by mixing, kneading and extruding. [0003] Due to the use of stabilizers, plasticizers and various fillers and other additives in terms of environmental protection vary. Generally, it is measured by the testing methods and standards of ROHS or REACH. Divided into environmental protection and non-environmental protection PVC cable materials. Environmentally friendly cable materials, that is to say, after the cable materials are successfully prepared, they are tested on ICP testing equipment with ...

Problems solved by technology

Non-environmentally friendly cable materials Non-environmentally friendly cable materials generally use lead salts as stabilizers, because they contain heavy metals such as lead, chromium, cadmium, mercury, barium, etc., which will cause great damage to the environment and human health, and are receiving more and more attention. countries that restrict or prohibit the use of
