Abstract
The invention relates to a formula of a rubber sheath. The formula comprises the following components by mass percent: 60-66% of ethylene, 25-33% of propylene, 3-5% of zinc oxide, 1.5-2% of stearic acid, 0.1-0.2% of pine tar, 0.1-0.3% of sulphur, and 1-3% of dicyclopentadiene. The formula disclosed by the invention has the advantages of being low in cost, reasonable in proportion, stable in performance, safe to use and the like; the molding quality of the rubber sheath can be ensured; the production benefit of a factory is also improved.
Description
Technical field
The present invention relates to the elastomeric material technical field, is a kind of formula of rubber sheath specifically.
Background technology
Rubber sheath is applicable to hydralic hose, electron device, running gear or locomotive element etc., plays the provide protection to internal product.Not only can improve aesthetics and constraint effect, and can make the life of internal product.Therefore, rubber sheath is widely used in the industries such as medicine, electrical equipment, chemical industry, food, automobile, machinery.But the situations such as due to raw material, manufacturing process or human factor, the normal appearance of most rubber sheath in the market is aging, distortion, breakage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of advantages such as with low cost, reasonable ratio, stable performance and use safety that have, and can guarantee the formula of rubber sheath Forming Quality, i.e. a kind of formula of rubber sheath.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of formula of rubber sheath, this formula comprises ethene, propylene, zinc oxide, stearic acid, Stockholm tar, sulphur and dicyclopentadiene, the shared mass percent of described each component is as follows:
The shared best in quality per-cent of described each component is as follows:
The performance of described each component and effect are as follows:
Ethene: ethene is important organic chemical industry's basic raw material, and ethene and propylene polymerization produce ethylene-propylene rubber(EPR).In addition, ethene is also one of basic raw material of petrochemical complex.Aspect synthetic materials, ethene is in a large number for the production of polyethylene and ethylene-propylene rubber(EPR) etc.
Propylene: propylene is the basic raw material of three large synthetic materialss, mainly for the production of vinyl cyanide, isopropyl alkene, acetone and propylene oxide etc.Propylene and vinyl polymerization produce ethylene-propylene rubber(EPR).
Zinc oxide: the effect of following six aspects is arranged: 1, active zinc flower mainly is used as the strengthening agent of rubber, so that rubber has good erosion resistance, tear strength and elasticity, elongation; 2, for the promotor of rubber vulcanization process, be the Multifunctional rubber Synergist S-421 95, the vulcanization leveller that is mainly used in natural gum, synthetical glue, the latex strengthening agent of holding concurrently; 3, when the vulcanization leveller, in sizing material, be evenly distributed, large with the contact area of hydrogen sulfide, carry out the surface reaction opportunity larger, add the promoting catalysis that this active oxidation zinc product has active substance, make zinc oxide be converted into the transformation efficiency of zinc sulphide high; 4,, as the sulfidation-oxidation agent, its effect is to promote the promotor activity, reduces the consumption of promotor, shortens curing cycle; 5, can accelerate vulcanization rate, improve the thermal conductivity of cross-linked rubber, make sulfuration more thorough; 6,, in rubber industry, particularly, in the transparent rubber production of articles, active zinc flower is fabulous vulcanization leveller.
Stearic acid: the effect of four aspects is arranged: 1, softening and plastification; 2, as exterior lubricant; 3, the abundant diffusion of favourable carbon black, white carbon black and zinc oxide; 4 and the reaction of zinc oxide or basic-type accelerator can promote its activity, or main vulcanization accelerator additive, can play the effect of the second promotor.Can make sclerosis accelerate.
Stockholm tar: following three aspect effects are arranged: 1, there is to well softening dissemination the sizing material of carbon black; 2, increase the viscosity of sizing material, make the sizing material soft smooth; 3, goods are had to cold-resistant anti-scorch negative catalysis effect.
Sulphur: be mainly used to vulcanize ethylene-propylene rubber, also can improve the thermotolerance of rubber.
Dicyclopentadiene: the 3rd monomer of terpolymer EP rubber.
The invention has the beneficial effects as follows: the present invention has the advantages such as with low cost, reasonable ratio, superior performance, use are stable, has improved the productivity effect of factory.
