Description

Ceramic polyolefine material and preparation method thereof
Technical field
The invention belongs to electric wire and cable material technical field, be specifically related to a kind of ceramic polyolefine material, and relate to its preparation method.
Background technology
Along with the remarkable improvement of economic growth and social progress and standard of living, people to such as eating, wear, live, go, with and so on the comprehensive raising of awareness of safety, wherein, increasingly harsh to Electrical Safety.In view of the important carrier that electric wire is using electricity system, the thus concern of its security extremely people.Because flame resistant cable can ensure within the rational time period that under state of combustion emergency service, equipment continue to maintain certain working time, for the escape of fire trapped personnel, suing and labouring of firefighter are got the valuable time and/or create favourable condition, thinking highly of thus comparatively by industry.
In recent years, China's town and country construction develops rapidly, electricity capacity improves constantly, if the buildings of Highrise buildings, megastore, subway, tunnel and so on adopts traditional 0.6/1KV low-voltage distribution, so in cable consumption, laying installation workload and lay in space consumption and maintenance cost and all need very large input, especially, cabling causes difficulty not only to daily managing and protecting too much, and has an impact to safety.In order to solve an actual power difficult problem, at present, pressure (6-35KV) power supply during Highrise buildings, megastore etc. start to adopt, thus make in the electricity consumption requirement of this place of adaptation, the market requirement of low pressure flame resistant cable constantly increases.
Can be seen in being suitable in disclosed Chinese patent literature, the technical intelligence of the flame resistant cable that the fire-resistant occasion of low pressure uses, as Authorization Notice No. CN101169993B recommendation has " middle pressure flame resistant cable ", comprise the insulated core of middle laminated structure, the flame retardant coating in outside and oversheath, flame retardant coating is inner side refractory inorganic fiber thermofin, the normal use in outside is soft type thermo-setting elastomer, meet and catch fire, change the composite fire thermofin of gear fire screen thermosphere into, wherein, thermo-setting elastomer is by the silica-based resilient material of 30-50Wt%, the mineral filler of 40-60Wt%, in 5-15Wt% low temperature frit and 4-10Wt% vulcanizing agent extrusion shaping and form through carbonization.The shortcoming of this patent formula is: when deployed, needs to rely on special Rubber Extruder to be extruded, and need carry out sulfidizing through vulcanization process, thus technique relative complex, restricted application; If CABLE MATERIALS is made silicone rubber belt, and be wrapped in the electric wire course of processing to outside cable core, so production efficiency is low and cost is high, is unfavorable for industrial amplification production; And for example application for a patent for invention publication No. CN103525092A provides " a kind of Ceramic silicone rubber cable material and preparation method thereof ", formula (counting by weight): silicon rubber 80-90 part, natural rubber 10-20 part, mineral silicate 20-30 part, antimonous oxide 10-15 part, ammonium polyphosphate 10-20 part, zinc oxide 4-6 part, anti-aging agent (DTPD) 1-2 part, spray carbon black 20-30 part, light calcium carbonate 10-20 part, hypo-aluminum orthophosphate 14-16 part, calcium stearate 1-2 part, tetramethylolmethane 1-2 part, talcum powder 1-2 part and modified filler 12-14 part.This patent application scheme all adopts Ceramic silicon rubber material as aforementioned CN101169993B, and this patent application scheme exists the described shortcoming of aforementioned CN10116999B equally except complexity of filling a prescription; For another example Authorization Notice No. CN101404189B introduces " a kind of fast ceramic flame-resistant cable and preparation method thereof " (one of contriver of this patent is first contriver of the application), this patent formula possesses ceramic performance and objectively can embody the technique effect of the 0023 to 0025 section, its specification sheets record, but formula and complicated process of preparation, and due to containing more polyethylene (parts by weight in system are 30-40 part), thus processing temperature is higher, energy consumption is large, loses relatively cheap; And then disclose " a kind of fast ceramic flame-resistant cable " as application for a patent for invention publication No. CN103509237A, very complicated by the 0005th section, the specification sheets of this patent application its formula known, and because filler accounting is lost rationally, the intensity of porcelain compound, compactness are difficult to reach expection; More and as application for a patent for invention publication No. CN103865166A discloses there is " low smoke and zero halogen ceramic cable material of polyolefin and preparation method thereof ", this CABLE MATERIALS is when extruding separately, there is good porcelainization crust performance, but after extruding other materials again at its skin, its porcelainization crust performance obviously declines, and resistates intensity is very low.
