Abstract
The invention provides a kind of flame-retardant plastic composition of being formed with polyvinyl chloride (PVC) RESINS and fire retardant, softening agent, thermo-stabilizer, lubricant, weighting agent, these compositions are after pre-treatment, in plastics extruder through the plasticizing of heating, and by mould and traction, the prepared electricwire conduit of cooling forming, barrel and web member, it has characteristics such as flame retardant properties height, good insulation preformance and high strength, and have lightweight, protection against the tide, ageing-resistant, corrosion-resistant, can plant arbitrarily, cut, bore, saw, advantage such as nail, the oxygen index of product reaches more than 40.
Description
The invention relates to the high molecular fire retardant composition, and fire-retardancy electric wire sleeve pipe and the goods made with said composition.
At present, covil construction both domestic and external, high-rise building, industrial and mining enterprises and underground works etc., when laying wire and installation electrical equipment, all use goods such as plastics, timber, metal sleeve in a large number, these material major parts have flammable or nonisulated property, therefore, the fire and the fatal accident that cause owing to electric wire or electrical leakage occur repeatedly, and cause the heavy losses of national wealth and people's life.For this reason, from the angle of fire prevention, personnel safety and beautiful decoration, all need existing product is studied improvement, this also is an urgent demand that public security fire-fighting department proposes.
The objective of the invention is to provide a kind of and have high flame retardancy, high insulation and high-intensity material, and make goods such as fire-resistant wire plastic casing, barrel, web member with these materials with plastics attribute.
The present invention includes the compound method of flame-retardant plastic composition and the complete processing two aspect contents of product, it is to realize by following mode: on compound method, with 100 parts of (following all calculations by weight) polyvinyl chloride (PVC) resins is base-material, adding 4-8 part antimonous oxide and 3-5 part chlorinated paraffin (chlorinity 70%) is fire retardant, 1-2 part dibutyl phthalate and 2 parts of dioctyl phthalate (DOP)s are made softening agent, 3.5-4 the lead sulfate tribasic of part, 1.5-2.2 part barium stearate and 1-2 part lead stearate are thermo-stabilizer, 0.2-1 part paraffin wax lubricant, 5-20 part light calcium carbonate and 3-4 part titanium dioxide are weighting agent.
Above-mentioned raw materials is carried out pre-treatment, promptly polyvinyl chloride (PVC) RESINS and antimonous oxide are added in the kneading machine (the kneading machine stirring velocity is 350-400 rev/min), in 30-60 ℃ of temperature, fully stirred 5-20 minute, treat to add again when temperature continues to rise to 80-90 ℃ other raw materials in the above-mentioned prescription, continue to stir 5-20 minute, after making the material homodisperse, put normal temperature cooling, satisfy flame-retardant plastic composition.
Product processing technique: above-mentioned composition is added in the plastics extruder, and plasticizing mixes under 160-200 ℃ of temperature, with garden type or xenotype mold plastics composite is extruded, and makes injection-molded items such as required fire-resistant wire sleeve pipe, barrel, web member.For product (sleeve pipe, barrel, web member) type shape can be fixed up on request, after product is extruded from mould, need to make product enter Vacuum shaping cover (vacuum tightness is 200-450mm/Hg) and the cooling of wind groove continuously by tractor.Table one and table two are prescription and test datas that the present invention screens in a large amount of research trials:
Formula test information slip one
Technical process:
(seeing accompanying drawing)
The product of producing with the present invention, except having fire resistance height, good insulation preformance and high-intensity characteristics, also have lightweight, protection against the tide, ageing-resistant, corrosion-resistant, the advantage of can plant arbitrarily, cut, bore, saw, following closely, construction install convenience, good decorative property, with low cost, the gas that product gives out in flame is than general plastics much less, and oxygen index (OI) then is much higher than the requirement of fire prevention index (〉=32).
Embodiment:
The vertical kneading machine of φ 800 * 1000m/m is preheated to 40-50 ℃, adding 100 parts of (following all calculations by weight) polyvinyl chloride resin powder material and 5 parts of antimonous oxides stirred 10-15 minute, stirring velocity 350-400 rev/min, when treating that temperature rises to 80-90 ℃, add 3.5 parts of tribasic lead sulfates immediately, 2.2 parts of barium stearates, 1 part of lead stearate, 0.2 part of paraffin wax, 5 parts of light calcium carbonates, 3 parts of titanium dioxides, 4 parts of chlorinated paraffins, continue to stir and to add each 2 parts of dioctyl phthalate (DOP) and dibutyl phthalates after 10-15 minute, and continue to stir and knead, discharge after making the material homodisperse, place under the normal temperature cooling stand-by.
The good flame-retardant plastic composition of above-mentioned pre-treatment is added φ sieve 65m/m bar plastics extruder, under 185 ℃ of temperature, composition is plastified, by garden type or xenotype mold material is extruded, material is extruded the back and is drawn by tractor, make material enter Vacuum shaping cover (vacuum tightness 400-450mm/Hg) and the cooling of wind groove, satisfy into product, and press certain-length product cutting packing warehouse-in.
