Abstract
The present invention relates to a linear low-density polyethylene fire-retardant sleeve pipe and a production method thereof. 100 of linear low-density polyethylene, 6% to 8% of chloroparaffin, 4.5% to 6% of antimonous oxide, 1% to 2% of antimony pentoxide, 0.5% to 1.5% of a resin acceptor, 0.3% to 0.6% of calcium bicarbonate and 5% to 8% of aluminium hydroxide are mixed together and are kneaded at the temperature of 90 to 110 DEG C, and then, after granulation, plasticization at the temperature of 120 to 150 DEG C, extrusion and coiling, are made into the pipe. With the characteristics of fire retardance, insulation, static electricity resistance, difficult ageing, good toughness, easy bending, convenient operation, etc., the linear low-density polyethylene fire-retardant sleeve pipe is suitable to be used as a conductor penetrating insulation sleeve pipe for construction, telecommunication, microcomputers, decoration, decoration construction and military engineering.
Description
The present invention relates to insulation thimble that conductor passes and preparation method thereof.
In recent years, the urban and rural buildings thing adopts plastic casings to replace conventional metals sleeve pipe in the fitting-out works such as dark power circuit that applies and telecommunication, microcomputer, decoration towards large-scale, high-rise, luxurious development in the buildings more.
But currently used plastic casing mainly is high-pressure polyethylene or polychloroethylene pipes.The high-pressure polyethylene sleeve pipe, resistance to compression, bending resistance all can reach the technical requirements of construction, but exist the shortcoming of inflammable, not antistatic and high-voltage breakdown, are the hidden danger that causes fire.PVC sleeve, though possess flame retardant resistance, material is crisp hard, and easy fracture is anti-aging, bending resistance is poor, uses inconvenience, and the construction waste wood is many.
The present invention is directed to the existing shortcoming of above-mentioned plastic casing and develop a kind of have resistance to compression, antistatic, anti-high pressure, difficult aging, particularly have high flame resistance, good toughness, convenient construction, as requested the linear low density polyethylene fire retardant sleeve of any scale.
The present invention is achieved in that
A kind of linear low density polyethylene fire retardant sleeve, its basic characteristics are: it is a main raw material with the linear low density polyethylene, is equipped with other industrial chemicals and makes fire retardant sleeve, and its proportioning raw materials is, the major ingredient linear low density polyethylene is 100 weight parts, adds: clorafin 6-8 weight part again; Antimonous oxide 4.5-6 weight part; Antimony peroxide 1-2 weight part; Coupling agent 0.5-1.5 weight part; Decabromodiphenyl oxide 0.3-0.6 weight part; Light calcium carbonate 3.5-5 weight part; Aluminium hydroxide 5-8 weight part.
The making method of aforesaid polyethylene fire retardant sleeve, be characterized in, above-mentioned various raw materials are prepared by described prescription, by operation manufacturings such as compound-kneading-granulations-plastify-extrude-coil, its processing parameter is: mediate temperature and be controlled at 90-110 ℃, plasticization temperature is controlled at 120-150 ℃, promptly can be made into linear low density polyethylene fire retardant sleeve.
The internal diameter size of product and cross-sectional shape can design according to customer requirements, realize that by changing the forcing machine mould performance index of this product are as follows:
Tensile strength＞12MPa; Elongation at break＞330%; Resistance to compression: be depressed into external diameter 1/2 place's non-cracking; Crooked 180 degree crack-frees, oxygen index＞27.0%, insulation resistance＞55000M Ω, withstand voltage 5000V/min does not puncture.
Can find out that by These parameters the linear low density polyethylene sleeve pipe of being made by the present invention has overcome the inflammable shortcoming of high-pressure polyethylene sleeve pipe.Overcome shortcoming such as inconvenient crooked break-in, scale and joint inconvenience in the hard fragility of PVC sleeve and the construction again, had concurrently simultaneously high-pressure polyethylene telescopic fracture resistance good, again can be arbitrarily crooked according to construction requirement, the advantage of intercepting scale and polyvinyl chloride high flame resistance.Its main flame retardant properties maintains the leading position.This product can be widely used in the urban and rural buildings thing and secretly apply the distribution line sleeve pipe, the aspects such as conveying of fire prevention such as engineering such as electronics, telecommunication, microcomputer, decoration, finishing and warehouse, military installations, inflammable gas, liquid.Linear low density polyethylene fire retardant sleeve is than low about 500 yuan of high-pressure polyethylene sleeve pipe cost of material per ton, can prevent effectively that fire from taking place, and is moulding the good material of Dai Gang, and its economic benefit is all more outstanding.
Embodiment 1: the major ingredient linear low density polyethylene is 100 weight parts, is equipped with clorafin 7 weight parts, antimonous oxide 5 weight parts, antimony peroxide 1.5 weight parts, coupling agent 1 weight part, decabromodiphenyl oxide 0.5 weight part, light calcium carbonate 4 weight parts; Aluminium hydroxide 6.5 weight parts by compound-mediate-make the technology of expecting-plastifying-extruding-coiling to process, are mediated temperature and are controlled at 100 ℃, and plasticization temperature is controlled at 120-150 ℃, promptly can be made into linear low density polyethylene fire retardant sleeve.
Embodiment 2: the major ingredient linear low density polyethylene is 100 weight parts, is equipped with clorafin 6 weight parts, antimonous oxide 4.5 weight parts; Antimony peroxide 1 weight part; Coupling agent 0.5 weight part, decabromodiphenyl oxide 0.3 weight part; Light calcium carbonate 3.5 weight parts; Aluminium hydroxide 6 weight parts promptly can be made into linear low density polyethylene fire retardant sleeve according to technology and the condition of embodiment 1.
Embodiment 3: the major ingredient linear low density polyethylene is 100 weight parts, is equipped with clorafin 8 weight parts, antimonous oxide 6 weight parts; Antimony peroxide 2 weight parts; Coupling agent 1.5 weight parts, decabromodiphenyl oxide 0.6 weight part; Light calcium carbonate 5 weight parts; Aluminium hydroxide 8 weight parts promptly can be made into linear low density polyethylene fire retardant sleeve by technology and the condition of embodiment 1.
