Description
Technical field
The invention belongs to high-temperature silicon disulfide rubber Material Field, and in particular to a kind of high-flame-retardanthalogen-free halogen-free environmental protection silicon rubber and its
Preparation method.
Background technology
Silicon rubber be it is a kind of have inorganic and organic nature macromolecular elastomer material concurrently, its main chain is former by silicon atom and oxygen
Son is alternately constituted, and the silicon oxygen bond (- Si-O-) bond energy for being formed is very big, bigger than the carbon-carbon bond (- C-C-) bond energy of traditional rubber
It is many, with very high heat endurance and extraordinary weatherability, while silicon rubber also has, HRR is low, charring rate is high,
Nontoxic, smokeless the characteristics of, possesses relatively good fire resistance.Therefore silicon rubber is that the application of the fields such as Aero-Space is extremely wide resistance to
Hot material.
But, silicon rubber can be in itself burning, and in atmosphere silicon rubber can glow phenomenon.Silicon rubber it is a lot
Use environment requires that it has to possess good fire resistance, therefore research high flame retardancy silicon rubber material is very important.
Although the anti-flammability of silicon rubber, such as platinum compounds, deca-BDE or hexichol can be improved using some means
Ethane makees fire retardant, Application No. CN200410077503.5, CN201310626801.4, CN201510064816.5,
CN201310461092.9、CN200810196197.5、CN200910185447.X.But these fire retardants are being manufactured or made
Can bring very big pollution to environment with during, and silicon rubber many use occasions be requirement halogen-free environmental (for example
Subway, automobile, building, hospital, Aero-Space etc.).Therefore, not only fire-retardant but also Halogen silicon rubber is very necessary for research.
Although the patent of application number CN201410826700.6 discloses a kind of halogen-free flameproof heat vulcanized silicone rubber, its limit
Oxygen index (OI) can exceed that 40%, and vertical combustion can reach FV-0 levels, but use isocyanates in that patent, the body to people
Health has very big harm.Although the patent of Application No. CN201210257988.0 discloses a kind of Environment-friendlyflame-retardant flame-retardant silicone rubber
Vertical combustion can reach FV-0 levels, but oxygen index (OI) is not described, and wherein with the addition of melamine, and melamine
Generation cyanide severe toxicity gas can be decomposed at high temperature.Other Environment-friendlyflame-retardant flame-retardant silicone rubber patents (CN201110348676.6,
CN201310265272.X, CN201310267082.1, CN201310267097.8) fire resistance of silicon rubber is not all carried out
Description.Therefore develop a kind of both with very high fire resistance, again will not be to the healthy fire-retardant Halogen for working the mischief of people
Environmentally friendly silicon rubber is very necessary.
