Abstract
The invention discloses a low-smoke, halogen-free and flame-retardant cable material and a preparation method thereof. The method comprises the steps of sequentially adding 50 to 55 parts of ethylene-ethylic acid ethylene copolymer, 30 to 45 parts of aluminum hydroxide, 16 to 20 parts of a charring agent, 6 to 9 parts of chlorinated paraffin, 2 to 3 parts of a silane coupling agent, 1 to 2 parts of an antioxidant, 5 to 7 parts of nanosilicon dioxide, and 1 to 2 parts of a lubricating agent into a mixing tank, so as to be uniformly mixed, and then performing extrusion pelletization through a double-screw extruder. The cable material and the preparation method overcome the defects of poor flame retardance and poor mechanical property of cable materials in the prior art.
Description
Technical field
The present invention relates to field of cable technology, relate in particular to a kind of fireproofing cable material without halide and preparation method thereof.
Background technology
Along with the fast development of the industries such as China's metallurgy, electric power, electronics, automatization and informatization and network, the consumption of the flame-retardant electric wire and cables such as power cable supporting with it, control cables, signal cable, instrument cable computer cable is sharply increased.
Traditional flame retardant cable mostly adopts polyvinyl chloride as insulation or sheath, although polyvinyl chloride has the features such as good flame resistance, the modest and amiable expressing technique of valency be good, but because it contains halogen, a large amount of hydrogen halide and dense smoke can be discharged when running into fire burning, cause " the secondary harm " of fire, thus increase the loss of fire.Confirm through scientific research, the harm that halogenide causes HUMAN HEALTH and environment is more and more serious, and people are attaching importance to environmental protection more and more, and European Union etc. are proposed the regulations used polyvinyl chloride restriction.At home, namely Beijing Power Supply Bureau sends the documents and provide against polyvinyl chloride electric wire and use in this office system in March, 1998, and " covil construction electric wire fire protection design code " that East China Municipal Architecture Design and Research Institute in 2002 is released clearly proposes the requirement using low smoke no-halogen wire cable.These, make low-smoke halogen-free flame-retardant electric wire and cable be used widely above, and present very large development potentiality, particularly all requires to use low-smoke halogen-free flame-retardant electric wire and cable in densely populated occasions such as subway, Highrise buildings, various venue buildings.But there is the defects such as the not high and electrical insulation properties of flame retardant resistance is poor in the low smoke halogen-free fire retardant polyolefin cable material on object market, can not practical requirement.
Summary of the invention
The object of the invention is to solve the above-mentioned problems in the prior art, a kind of fireproofing cable material without halide and preparation method thereof is provided, instant invention overcomes the defect that CABLE MATERIALS in prior art also exists poor fire and bad mechanical property.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of fireproofing cable material without halide, is characterized in that the raw material comprising following parts by weight:
Ethylene vinyl acetate 50-55 parts;
30-45 parts, aluminium hydroxide;
Char-forming agent 16-20 parts;
Clorafin 6-9 parts;
Silane coupling agent 2-3 parts;
Protective agent 1-2 parts;
Nano silicon 5-7 parts;
Lubricant 1-2 parts.
Described lubricant is paraffin, Zinic stearas or calcium stearate.
A preparation method for fireproofing cable material without halide, is characterized in that comprising the following steps:
(1), get the raw materials ready by above-mentioned parts by weight, and then ethylene vinyl acetate, aluminium hydroxide, char-forming agent, clorafin, silane coupling agent, protective agent, nano silicon and lubricant are joined in agitation vat mix successively, wherein, in reinforced process, the rotating speed of stirrer is 80-100r/min, after having fed in raw material, the rotating speed of stirrer is 280-320r/min.
(2), by the raw material twin screw extruder extruding pelletization after mixing, extrusion temperature controls at 120-130 DEG C.
Employing the invention has the advantages that:
One, the aluminium hydroxide in the present invention, char-forming agent and clorafin all have good flame retardant properties, these three kinds of components are evenly combined by specific proportioning, just can promote the flame retardant properties of electric wire further, and then can effectively prevent electric wire from occurring in a fire " secondary harm ".By the combination of these three kinds of specific components of nano silicon, protective agent and silane coupling agent, each component in CABLE MATERIALS can be made to be closely linked, and then the resistance to deterioration of electric wire, chemical resistant properties, tensile strength and work-ing life can be promoted.
Two, in the present invention, when raw material is added in stirrer successively, the rotating speed of stirrer is 80-100r/min, and raw material is all being added after in stirrer, the rotating speed of stirrer rises to 280-320r/min, such set-up mode makes the raw material added successively to be dispersed in agitator, and can be issued to mixed uniformly for each component object in the prerequisite reducing churning time fast.
Three, fireproofing cable material without halide of the present invention has excellent flame retardant properties, not halogen-containing in material, a large amount of smog and hydrogen halide can not be discharged during burning, there is good safety and environmental-protecting performance, simultaneously, this low-smoke halogen-free flame retardant material also has good mechanism performance and processing performance, is applicable to all trades and professions.
