Description
Technical field
The present invention relates to rubber materials, more specifically a kind of Environment-friendlycorrosion-resistant corrosion-resistant epichlorohydrin rubber.
Background technology
Epichlorohydrin rubber is that main chain is made up of C-O and C-C, the saturated rubber of the chloride atom of its side chain, and main chain is ether type structure, and owing to there being Sauerstoffatom to exist, molecule is easy to rotate, and main chain is submissive, without double bond existence, side chain contains polar group or unsaturated link(age).This constitutional features determines that polyether rubber has the feature of resistance to ozone, resistance to weather, chemicals-resistant, cold-resistant and good processability.
Because it has These characteristics, epichlorohydrin rubber is mainly for the manufacture of fluorine Lyons refrigerant sealing member, sebific duct; The various oil seals of engineering machinery, transformer barrier film, silencing and damping material, tank linning; Well recovery equipment sealing member, oil well high-tension piston head part, natural gas high pressure valve membrane and anemometer, oil fuel pump barrier film; Automobile sealing member, sebific duct, flexible pipe, oil blocking cover, shock absorbing ring; Chemical fertilizer hydrogen nitrogen compressor and copper liquid pump sealing member; Various cable sheath and high-temperature electric machine fixture wire; Homogeneous phase ion exchanges electrons instrument; Aviation oil resistant film; The snappiness sizing agent etc. of tamanori and flexible printed circuit board pasted by fiber.
But in prior art, be tri-lead tetroxide in the vulcanization system of epichlorohydrin rubber, lead has toxicity, causes great harm to environment, therefore needs lead-free epichlorohydrin rubber of developping production.
Therefore the patent No. is 200910149270.8 technologies of preparing disclosing a kind of environmental protection epichlorohydrin rubber, and it adopts lead-free 2,4,6-3 thiol group sulfo-triazines as vulcanizing agent, meets the requirement of environmental protection.
And for example the patent No. be 200810010681.4 disclose a kind of unleaded, without nickel epichlorohydrin rubber, its adopt unleaded, make vulcanizing agent, not leaded, nickel without the vulcanizing agent TCY of nickel, also meet the requirement of environmental protection.
But due to containing chlorine, it has corrodibility to metal die, the mould after corrosion produces corrosion pit, and make mould have salient point, use on the rubber of such die production and will produce concave point, product has defect.
Be 201110001885.3 disclose a kind of epichlorohydrin rubber composition for above-mentioned shortcoming application number, it adopts stearylamide/polyethylene wax, they and epichlorohydrin rubber consistency are good, molecular chain and the molecular chain that can be deposited in epichlorohydrin rubber are direct, reduce the internal friction of polymer molecule, reduce the melt-flow viscosity of polymkeric substance, improve the slip between rubber and metal, colleague produces one deck sealing coat on the surface of rubber, decrease the contact between epichlorohydrin rubber and metal die while playing the effect of the demoulding, thus play the phenomenon slowing down metallic corrosion.
This patent application, after with the addition of traditional component, additionally with the addition of again acyl amine/polyethylene wax, adds the kind of component, cause the raising rising basis.
Summary of the invention
For above deficiency, the invention provides a kind of epichlorohydrin rubber that can reach environmental protection and resist metal corrosion without the need to additionally adding other components.
