Abstract
The invention discloses a kind of high-density fire-proof silicone adhesive and its preparation process, the raw material including following parts by weight: 95-108 parts of base rubber, 0-30 parts of plasticizer, 50-300 parts of flakey powder, 0-150 parts of non-reinforcement powder, 0-100 parts of reinforced filling, 0.01-20 parts of crosslinking agent, 0-5 parts of coupling agent and 0.0001-10 parts of catalyst.This product raw material sources are extensive, this product uses flakey powder, and flakey powder has high temperature resistant, acid and alkali-resistance, the low feature of moisture permeability, different mutual laminated arrangements can be formed after additive amount appropriate, and then high temperature or flame is prevented to penetrate, and reach fire-retardant purpose, under mating reaction by flakey powder and remaining raw material, also there is good radiation hardness, fire protecting performance, production cost is low, has wide prospect of the application in the case where without using fireproof powder and metal powder.
Description
Technical field
The present invention relates to rubber materials, specifically a kind of high-density fire-proof silicone adhesive.
Background technique
As people's lives are more and more intelligent, demand of the people to electricity is also more and more, and power plant is also more and more,
Substation is more and more, and the accumulation regions apart from people are also increasingly closer.Electromagnetism ionising radiation is more and more, and people are to anti-spoke of preventing fires
It is also higher and higher to penetrate requirement.
Fire-proof silicone rubber is a kind of people's commonly radiation proof material, it uses zinc borate, magnesium hydroxide, hydroxide
Aluminium, nitrogen system, phosphorus system, the compound system of nitrogen phosphorus, halogen-containing flame retardant, Sb system fire retardant, rare earth oxide etc., independent or several fireproof powders
Compound action, by fire retardant decompose generate aqueous vapor, two vaporized carbons, non-inflammable gas or powder can prevent further to fire
It burns, or captures the burn free radical generated or several fire retardant cooperative flame retardants etc. and achieve the purpose that prevent burning.Fire prevention silicone rubber
Glue is to improve radiation resistance by improving density, and in order to improve density, mostly uses metal powder such as, iron powder, zinc powder, aluminium
Powder, lead powder, the specific gravity such as tungsten powder larger substances increase density.
Although existing fire-proof silicone rubber can reach fire protection requirement by fireproof powder, exist not environmentally, it is resistance to
The disadvantages of warm nature is bad, and resistance to acid and alkali is bad, generates toxic gas or solid when decomposition, expensive；These metal powders are easy
It is oxidized to bulk shape oxide and then influences silicone adhesive performance or be more toxic, expensive, this is all the use band of people
Inconvenience is carried out.
Summary of the invention
The purpose of the present invention is to provide a kind of high-density fire-proof silicone adhesives, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:
