Description
Technical field
The present invention relates to fire protection flame retarding field of cable technology, more particularly to it is a kind of can ceramic silicon rubber and its preparation
Method.
Background technology
Can Ceramic silicon rubber be a kind of new applied fireproofing, at normal temperatures the elasticity with usual silicone rubber,
Processability and electrical insulating property.Under the hot conditions of naked light ablation, hard ceramic body can be transformed into, protect internal material
From high temperature, the fire-retardant effect of fire insulation is played.At present can the silicon rubber of ceramic be mainly used as the anti-of wires and cables industry
Fiery material.When fire occurs, electric wire is by forming ceramic body case, and retainable inner lead is within a certain period of time just
Often use.Therefore exploitation can Ceramic silicon rubber, be realize its broader applications important research work.
The content of the invention
The present invention relates to can ceramic silicon rubber and preparation method thereof, it is therefore an objective to provide it is a kind of it is nontoxic, fire-retardant, environmentally friendly,
Flame retardant cable scheme that is heat safe and adapting to important engineering demand.
The technical solution that the present invention takes for it is a kind of can ceramic silicon rubber composite material, it is characterised in that raw material group
Into including basic silicon rubber 40~70%, Vitrified powder 20~40%, kaolin 5~15%, heat filling 2~8%, fluxing agent 1
~5%, hydroxy silicon oil 1~5% and vulcanizing agent 1~3%.The fluxing agent is low softening point (350~500 DEG C) glass dust；Institute
It is aluminium nitride to state heat filling；Vulcanizing agent is double -25.During preparation, first heat filling and fluxing agent are uniformly mixed, then
Sintered 45~60 minutes in being 350~500 DEG C in temperature, the composite fluxing agent with heat conduction is ground into after cooling；Then
Silicon rubber, Vitrified powder, kaolin, hydroxy silicon oil, composite fluxing agent are added in rubber internal mixer, add vulcanization after mixing
Agent, obtained after mixing rubber compound park, back mixing；Gained rubber compound is vulcanized again, one step cure temperature conditionss for 150~
180 DEG C, the time is 10~20 minutes；Post vulcanization temperature is 180 DEG C, when the time is 2~4 small；Finally by vulcanizate 700~
When progress porcelainization 1~3 is small in 800 DEG C of Muffle furnace, being made after furnace cooling can Ceramic silicon rubber.
The problem of technical solution that the present invention takes effectively prevents existing Ceramic silicon rubber common, that is, sintering
During the ceramic layer that gradually forms of surface can play heat-blocking action, it is suppressed that heat is internally spread outside silicon rubber, is led
Causing the fluxing agent (low softening point glass dust etc.) of internal layer can not melt to form liquid phase in time so that ceramic body easily forms pine
Scattered structure, final porcelain intensity is not high.By the adjustment of material composition, the present invention obtain can Ceramic silicon rubber can be
(700~800 DEG C) realize the porcelain of high intensity at relatively low temperature, ensure that the fire-retardant effect of fire insulation.
The present invention obtain can Ceramic composite material typical performance result be：
