Abstract
The invention discloses a polyvinyl chloride (PVC) cable sheath material and a preparation method thereof. The PVC cable sheath material comprises 100 parts of PVC resin, 30-50 parts of plasticizer, 3-7 parts of compound stabilizer, 20-40 parts of active calcium carbonate, 5-15 parts of kaolin, 5-15 parts of aluminum hydroxide, 3-6 parts of antimony trioxide, 3-5 parts of zinc borate and 0.5-1.5 parts of aromatizer. In the cable sheath rubber disclosed by the invention, through the optimal combination of aluminum hydroxide, antimony trioxide and zinc borate, the carbonization amount is improved by approximate 50%; the smoke generation amount during naked flame combustion is reduced by 30-50%, and the limiting oxygen index (LOI) is improved to 33; by selecting a proper plasticizer, the material has excellent low-temperature and high-temperature resistance at the same time, and the use temperature of the material is (-30)-90 DEG C; and a mint-flavored essential oil aromatizer is added to the material, so that the obtained product has aromatic odor and has the actions of eliminating nausea, nervousness and tension headache and dispelling mosquito.
Description
Technical field
The present invention relates to the polymeric material field of power cable, particularly a kind of PVC sheath material and preparation method thereof, by the optimization to each component reach environmental protection, fire-retardant, do not drip the combustion and superior anti-low/performances such as high temperature, and has an aromatic odour, can be used for preparing the sheath of electric wire, be particularly useful for producing the environment-friendly type electric wire product supporting with the household electrical appliance class.
Background technology
A large amount of fire reports confirm cigarette and the toxic gas that causing death's arch-criminal generates when being the plastics burning.Particularly for Highrise buildings, situation is more obvious.The fatalities that takes place in the fire has 80% to be because cigarette and suffocating of toxic gas are caused according to statistics.In addition, cigarette reduces the visibility of scene of fire greatly, the time of affecting fire extinguishing adversely and rescuing lives and properties.Because polyvinyl chloride and polyethylene, polypropylene, polystyrene and ABS are referred to as five big resins for universal use, are China first, second-biggest-in-the-world universal synthetic resins material, are widely used in aspects such as all kinds of building materials, all kinds of daily necessitiess.Therefore become in recent years that one of emphasis research topic is exactly cigarette amount and the toxic gas volume that generates when reducing the plastics burning in the flame retardant plastics field.
Present domestic electric wire PVC sheath series products also has sizable share.There is quite serious pollution in conventional PVC protective case wire cable---when manufacturing, use and waste treatment, all can produce objectionable impuritiess such as a large amount of Dioxins, chlorine hydracid, lead.During the burning of PVC sheath material very big dense smoke can take place, and produce deleterious HCL gas; And contain Pb(lead in most of PVC sheath material), the Cd(cadmium) etc. (as cable stablizer) multiple harmful heavy metal, can cause certain harm to HUMAN HEALTH; After burning or burying, can cause soil and contaminated water source.For this reason, parliament of European Union and EU Council have passed through the RoHS instruction in January, 2003, full name is The Restriction of the use of certain Hazardous substances in Electnical and Electronic Equipment, promptly some objectionable impurities instruction is used in restriction in electronic electric equipment, also claims 2002/95/EC instruction.
Summary of the invention
Technical problem to be solved by this invention provide a kind of environmental protection, fire-retardant, do not drip combustion and anti-low/the PVC sheath material of better performances such as high temperature and preparation method thereof, this sheath material also has aromatic odour, and reaches comprehensively and meet the ROSH command request.
A kind of PVC cable jacket material of the present invention, it comprises 100 parts of polyvinyl chloride resins, 30～50 parts in softening agent, 3～7 parts of one package stabilizers, 20～40 parts of treated carbonatess, 5～15 parts of kaolin, 5～15 parts in aluminium hydroxide, 3～6 parts of antimonous oxides, 3～5 parts of zinc borates, 0.5～1.5 part of perfume compound, more than is mass fraction.
Described softening agent is the DOS(dioctyl sebacate) and clorafin, the mass ratio of DOS and clorafin is 1:2.
Described one package stabilizer is calcium/zinc composite stabilizer.
Described perfume compound be can be high temperature resistant 200 ℃ the minty note essential oil.
The preparation method of PVC cable jacket material of the present invention; its preparation process is: according to 100 parts of polyvinyl chloride resins; 30～50 parts in softening agent; 3～7 parts of one package stabilizers; 20～40 parts of treated carbonatess; 5～15 parts of kaolin; 5～15 parts in aluminium hydroxide; 3～6 parts of antimonous oxides; 3～5 parts of zinc borates; 0.5～1.5 part of perfume compound; add in the high speed kneader; speed with 800 commentaries on classics/min is mediated each component evenly; pass through 180 pairs of rank tablets press granulations under 135～165 ℃ temperature of Φ 75-Φ at last; cool off then; screening; weighing; the packing warehouse-in is finished the preparation of PVC sheath material
Each component is all selected the material that meets the ROSH command request for use among the present invention, reach environmental requirement, and in this prescription, add aluminium hydroxide, antimonous oxide and zinc borate and can solve fire-retardant and do not drip the combustion problem, by selecting 30～50 parts of suitable manufacturing methods for use, can solve the anti-low/high-temperature performance and the processing characteristics of material well.
Aluminium hydroxide is as the inorganic additive flame retardant of Halogen antacid, have filling, fire-retardant, press down the cigarette three efficacy, its fire retardation is mainly based on its dehydration endothermic effect, because losing crystal water need absorb heat, thereby the temperature that has suppressed the PVC sheath rises, and scission reaction is played restraining effect, makes the PVC jacket surface generate charcoal layer more closely, reduced the carbon particle in the cigarette, the amount of being fuming is descended; The crystal water of deviating from simultaneously forms steam and has watered down PVC sheath body oxygen concentration on every side, makes sheath body burning difficulty.
Antimonous oxide can play the cooperative flame retardant synergism with antimonous oxide because polyvinyl chloride is a polymer containing halogen, needn't add halogen-containing fire retardant in addition.Have part to be clorafin class softening agent in addition in 30～50 parts in softening agent, flame retardant effect is better.
Zinc borate acts in this sheath material, have fire-retardant, press down cigarette and suppress multiple functions such as twilight sunset, and can improve the electrical property of sheath material, breaking tenacity, elongation at break and the notched Izod impact strength of this sheath material are improved significantly.Zinc borate at the aflame behavioral mechanism of PVC sheath material is: in combustion processes, zinc borate decomposes, and the boron trioxide of generation forms one deck glassy mass and covers the sheath body surface, plays the effect that suppresses twilight sunset.And decompose the zn cpds that produces, and being present in the condensed phase, catalysis PVC deviates from HCl and promotes it crosslinked, improves neat coal amout, is lowered into the cigarette amount, stops burning to be proceeded.
The present invention cooperates by the optimization of aluminium hydroxide, antimonous oxide, zinc borate, can make neat coal amout increase nearly 50%.Give birth to the cigarette amount during naked light burning and reduce amplitude 30～50%, LOI brings up to 33.And by selecting suitable manufacturing methods for use, this material possesses good low temperature resistant/high-temperature behavior simultaneously, use temperature is-30 ℃～90 ℃, and added 0.5～1.5 part of high temperature resistant 200 ℃ minty note essential oil perfume compound in the material, make goods have aromatic odour, play eliminate to feel sick, anxiety and tension headache and dispel the mosquito effect.
