Abstract
The invention relates to a low-smoke fire-retardant PVC (polyvinyl chloride) cable material. The low-smoke fire-retardant PVC cable material is characterized by comprising the following components in parts by weight: 100 parts of PVC resin, 6-9 parts of a stabilizing agent, 25-35 parts of DOP (dioctyl o-phthalate), 4-6 parts of hydrated zinc borate, 20-40 parts of magnesium hydrate, 12-18 parts of TCP and 0.3-0.6 part of an antioxidant. The modified magnesium hydrate is selected as a fire retardant, and the cable material has superior fire-retardant performance after the fire retardant is added, so that the cable material can be prevented form falling down during combustion, and fire disasters cannot spread even if wire cables are laid in a cluster manner. The tensile strength of the cable material is greater than 11.8MPa, the breaking elongation of the cable material is greater than 250, the oxygen index of the cable material is greater than 31, and the dielectrical strength of the cable material is greater than 20.
Description
Technical field
The present invention relates to polymkeric substance cable material.Particularly relate to a kind of low-smoke and flame retardant PVC cable.Material.
Background technology
Along with the fast development of national economy, electric wire has become the indispensable material of national economy industry-by-industry, also is the misfortune source that causes fire simultaneously.A large amount of fire reports confirm that causing death's arch-criminal is salt and the toxic gas that Generation During Plastics Combustion becomes, particularly really build for height, situation is more obvious, the fatalities that occurs in the fire according to statistics has 80% to be because salt and suffocating of toxic gas are caused, because adjudicate two cases together ethene, polyethylene, polypropylene, polystyrene and ABS general designation five large resins for universal use, be widely used in all kinds of building materials, etc. the aspect.Therefore reduce cigarette amount that Generation During Plastics Combustion becomes and toxic gas volume and become one of problem of primary study in the flame retardant plastics field in recent years.Present domestic electric wire PVC insulation series products also has sizable share, and there is quite serious pollution in conventional PVC electric wire, all can produce the objectionable impuritiess such as a large amount of Dioxins, lead when manufacturing, use and waste treatment.The PVC insulating material can produce very large dense smoke when burning, and produces harmful HCL gas, can cause to people's health certain harm, burns and can cause the pollution that soil and who are drilled after fire is buried.Therefore how to design the flame-retardant electric wire and cable product that satisfies low cigarette, low toxicity, low corrosion and become the task of top priority of the whole society.
Summary of the invention
The objective of the invention is the defective and the deficiency that exist for solving above-mentioned prior art, and provide a kind of environmental protection, fire-retardant, do not drip so, and have the low-smoke and flame retardant PVC CABLE MATERIALS of high-and low-temperature resistance performance.
The technical scheme that adopts is:
A kind of low-smoke and flame retardant PVC CABLE MATERIALS, it is characterized in that: its component is to be made of polyvinyl chloride resin, stablizer, DOP hydration zinc borate, magnesium hydroxide, TCP, oxidation inhibitor, and its prescription is by weight: 100 parts of polyvinyl chloride resins, stablizer 6-9 part, DOP25-35 part, hydration zinc borate 4-6 part, magnesium hydroxide 20-40 part, TCP12-18 part, oxidation inhibitor 0.3-0.6 part.
Above-mentioned stablizer is calcium/zinc composite stabilizer.
Above-mentioned oxidation inhibitor is antioxygen 1010.
Low-smoke and flame retardant PVC cable performance test index of the present invention is as follows:
The present invention compared with prior art has the following advantages:
1, flame-retarding characteristic, the present invention selects the magnesium hydroxide of modification as fire retardant, can make material have superior flame retardant properties after the interpolation, can effectively prevent the low phenomenon that material produces when burning, even electric wire can working fire under the bunchy any intermediate position yet, its tensile strength is greater than 11.8MPa, and elongation at break is greater than 250, oxygen index is greater than 31, and dielectric strength is greater than 20.
2, low toxicity characteristic because material do not contain halogen, and unleaded, without sulphur, without toxicants such as antimony, thereby environmental pollution is very little.
3, high-temperature stability owing to added oxidation inhibitor, is that material has preferably heat resistanceheat resistant, ageing resistance.
