Description
Technical field
The present invention relates to a kind of CABLE MATERIALS, be specifically related to a kind of flexible fireproofing cable material without halide.
Background technology
Along with the enhancing of people's environmental protection and awareness of safety, the matter of each field to electric wire is more and more higher with performance requriements, the mortality ratio that the fire caused because of the aging of electric wire also gets more and more when how to reduce incidence and the fire of fire, low cigarette, Halogen, flame-proof environmental protection also become the developing direction of line cable industry.Wherein the demand of low cigarette, non-halogen flame-retardant cable is increasing, just progressively replaces PVC (polyvinyl chloride) CABLE MATERIALS.The production of current electric cable material with low smoke and halogen free is in polyolefin substrate, add a large amount of magnesium hydroxides or aluminium hydroxide to reach flame retardant effect mostly, but, a large amount of inorganic materials add the physical and mechanical properties that membership has a strong impact on CABLE MATERIALS.
Document (the development of fireproofing cable material without halide, Wuxi Light Industry Univ.'s journal, 2001,5 (20), Ni Zhongbin, Chen Mingqing, Yang Cheng, Liu Xiaoya) report adopt a large amount of magnesium hydroxide flame retardant EVA/HDPE mixture, even if but magnesium hydroxide after modification, still obvious impact is caused on the mechanical property of material.
For reduce a large amount of add mineral filler after impact that polymeric matrix mechanical property is caused, some supplementary additives can be added.Document (additive on the impact of flame-proof polyethylene system performance, fire science and technology, 2011,4 (30), Li Jianxin; Wu Jie; ) report employing white carbon black to strengthen the research of high carbon acid magnesium/aluminium hydroxide compositional flame-retardant polyethylene system mechanical property.But the cost of white carbon black own is higher, lack economy.In addition, a lot of CABLE MATERIALS is matrix with polyethylene, and cause line body too hard, construction difficult wiring, comfort is poor.
It is few that the inorganic combustion inhibitor of the relatively high filling of expansion type flame retardant has addition, the advantages such as flame retardant effect is obvious.Patent (publication number CN101070412A) reports the report adopting expansion type flame retardant flame-proof polyethylene, but expansion type flame retardant exists component easily separates out, and easily forms material surface bloom phenomenon, thus affects result of use.
In view of this, be necessary to develop a kind of softness in fact good, the electric cable material with low smoke and halogen free of excellent in mechanical performance, good economy performance, not easily bloom.Flexible electric cable material with low smoke and halogen free of the present invention makes the consistency between mineral filler and polymeric matrix significantly improve by the in-situ grafting polymerization of Acrylic Acid Monomer, and not only mechanical property, excellent fireproof performance but also flexibility are good for obtained CABLE MATERIALS.Can be used for manufacturing the electric wire that elevator cable, high-grade earphone cord, mouse lines etc. are flexible and flame-retardancy requirements is higher.
