Abstract
The invention discloses a low-cost environment-friendly flame-retardant cable. The cable is characterized by comprising the following raw materials in parts by weight: 80-120 parts of PVC (polyvinyl chloride) resin SG-2, 40-60 parts of TOTM (trioctyl trimellitate), 4-6 parts of epoxidized soybean oil, 6-10 parts of 70 chlorinated paraffin, 4-6 parts of antimony oxide, 0.3-0.7 part of antioxidant, 4-6 parts of calcined china clay, 8-12 parts of activated calcium carbonate and 5-9 parts of calcium-zinc compound stabilizer. The low-cost environment-friendly flame-retardant cable has the beneficial effects that the environment-friendly flame-retardant cable can avoid open fire burning in the process of approaching fire sources; flames only spread in a limited range; residual flames or residue burning fire can be extinguished by self in a limited time; an outer protective layer of the cable can only become flexible because of approaching the fire sources and can not catch fire, thus protecting all kinds of other equipment and avoiding greater losses; in the process, the environment-friendly flame-retardant cable can not generate smoke or is low in smoke and can not generate plenty of heavy black smoke as ordinary electric wires, thus minimizing harms to human bodies.
Description
Technical field
The present invention relates to plastic material field, refer more particularly to a kind of low-cost environmental-protecting flame retardant cable.
Background technology
Polyvinyl chloride, the English PVC that is called for short, is the thermoplastic resin being polymerized under initiator effect by vinylchlorid.It is the homopolymer of vinylchlorid.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.PVC is the white powder of amorphous structure, and the degree of branching is less.Industrial PVC molecular weight generally, in 50,000～120,000 scopes, has larger polymolecularity, and molecular weight increases with the reduction of polymerization temperature; Without definite melting point, 80～85 ℃ start to soften, and 130 ℃ become viscoelastic state, and 160～180 ℃ start to change into viscous state; There is good mechanical property, tensile strength 60MPa left and right, shock strength 5～10kJ/m2; There are excellent dielectric properties.But the poor stability to light and heat, more than 100 ℃ or through long-time exposure in sunshine, will decompose and produce hydrogenchloride, and further autocatalytically is decomposed, cause variable color, physical and mechanical properties also declines rapidly, must add in actual applications stablizer to improve the stability to light and heat.PVC is very hard, and solvability is also very poor, can only be dissolved in the minority solvents such as pimelinketone, ethylene dichloride and tetrahydrofuran (THF), and all stable to organic and mineral acid, alkali, salt, chemical stability reduces with the rising of use temperature.PVC is dissolved in acetone-dithiocarbonic anhydride or Acetone-Benzene mixed solvent, for dry-spinning or wet-spinning, forms fiber, claims polyvinyl chloride fibre, has difficult combustion, acid and alkali-resistance, antimicrobial, wear-resisting characteristic and has good heat retention and elasticity.
Most of plastics tools are flammable.Along with the widespread use of plastics at aspects such as building, furniture, traffic, Aeronautics and Astronautics, electrical equipment, improve flame retardant of plastic and become very urgent problem.Fire retardant is an analog assistant that suppresses polymer combustion, and they are the compound of V in the periodic table of elements, ⅦHe III family element mostly; The compound of phosphorus, bromine, chlorine, antimony and aluminium particularly.Fire retardant divides addition type and the large class of response type two.Additive flame retardant is mainly phosphoric acid ester and contains halophosphate, halohydrocarbon, weisspiessglanz, aluminium hydroxide etc.Advantage is easy to use, strong adaptability.But because addition reaches 10%～30%, often can affect the performance of plastics.Reactive flame retardant is actually the monomer containing ignition-proof element, so less on the impact of plastics performance.Common reactive flame retardant, as the halo acid anhydrides for polyester, for the tetrabromo-bisphenol of epoxy resin with for phosphorus-containing polyol of urethane etc.Fire retardant is used in the U.S. at first, and after the sixties in 20th century, consumption increases severely, and consumption is only second to softening agent at present.Consuming the maximum plastics variety of fire retardant is polyvinyl chloride, polystyrene, urethane foam, unsaturated polyester, ABS resin and polypropylene.Based on this, now study on this basis a kind of low-cost environmental-protecting flame retardant cable, possess good toughness and high burning-point, more safe.
