Description

Low smoke and zero halogen ceramic cable material of polyolefin and preparation method thereof
Technical field
The invention belongs to electric wire and cable material technical field, be specifically related to a kind of low smoke and zero halogen ceramic cable material of polyolefin, and relate to its preparation method.
Background technology
Along with the remarkable improvement of economic growth and social progress and standard of living, people are to the comprehensive raising of the awareness of safety such as eating, wear, live, go, using, wherein, increasingly harsh to Electrical Safety.In view of electric wire is the important carrier of using electricity system, thereby its security especially receives people's concern.Because flame resistant cable can ensure that emergency service, equipment continue the working time that remains certain under state of combustion within the rational time period, for escape, the suing and labouring of firefighter of fire trapped personnel are got the valuable time and/or create favourable condition, thereby being subject to thinking highly of of industry.
Known flame resistant cable mainly contains two kinds of the mica tape flame resistant cable of wrapped mica tape outside cable core and mineral insulated cables.But; in view of these two kinds of flame resistant cables produce and the link such as use in the deficiency that exists; people have developed ceramic silicone rubber for cable material; this ceramic silicone rubber for cable material is applied to cable and there is the good fire-retardant effect with suppressing to prolong combustion; and the amount of being fuming in when burning is little and can not produce toxic and harmful and can avoid secondary harm; after this external burning, can outside the cable core of electric wire, form the shell of hard difficult drop-off and use protection conductor, guarantee to transmit electricity and normally carry out." middle pressure flame resistant cable " and publication No. CN103525092A " a kind of ceramic silicone rubber for cable material and preparation method thereof " of providing that the exemplary of this cable is recommended as invention patent mandate notification number CN101169993B.
The existing shortcoming of CABLE MATERIALS that aforementioned CN101169993B and CN103525092A provide is: in the time using, need to rely on special Rubber Extruder to be extruded, and need to carry out sulfidizing through vulcanization process, thereby technique relative complex, restricted application; If CABLE MATERIALS is made to silicone rubber belt, and be wrapped to cable core in the electric wire course of processing, production efficiency is low and cost is high so, is unfavorable for industrial amplification production.
Invention patent mandate notification number CN101404189B introduces " a kind of fast ceramic flame-resistant cable and preparation method thereof ", this patent scheme can make up the described shortcoming of aforementioned CN101169993B and CN103525092A to a certain extent, but, ceramic polyolefine material formula complexity, preparation technology's link harshness are its shortcoming, and due to large (30-40 part) of poly parts by weight in formula, thereby processing temperature is high, energy consumption is large, causes finished product electric wire to lose cheapness.In addition, application for a patent for invention publication No. CN103509237A discloses " a kind of fast ceramic flame-resistant cable ", because this patent application scheme is used nearly 24 kinds of raw materials, thereby formula is very complicated, add the filler accounting lower (patent claims modified filler 12-15 part) in formula, the intensity of porcelain compound and fine and close effect are difficult to ensure.
In view of above-mentioned prior art, be necessary in addition rational modification, for this reason, the applicant has done row exploration of a specified duration and useful and experiment repeatedly, has finally formed technical scheme described below.
Summary of the invention
Task of the present invention is to provide a kind of and contributes to significantly to reduce the raw material type that uses in formula, be conducive to embody and good extrude processing characteristics, be of value to and ensure desirable flexibility and use conveniently to lay and have and be convenient to form ceramic housing outward and use the low smoke and zero halogen ceramic cable material of polyolefin that ensures the normal operation of circuit at conductor under burned flame or hot environment.
Another task of the present invention is to provide a kind of preparation method of low smoke and zero halogen ceramic cable material of polyolefin, the mica tape that the ceramic silicon rubber that the method technique is terse, can ensure that low smoke and zero halogen ceramic cable material of polyolefin is substituted the middle pressure flame resistant cable in prior art uses or glass and alternative low pressure flame resistant cable use and can meet industrial amplification production and require and ensure comprehensive embodiment of the technique effect of low smoke and zero halogen ceramic cable material of polyolefin.
