Description
Technical field
The present invention relates to a kind of rubber combination, relate in particular to a kind of have excellent resistance to acids and bases, stretch-proof, the rubber combination of tear resistance and application thereof.
Background technology
Gasket seal is oil, oil refining, petrochemical complex, a kind of sealing prod that pharmacy, chemical industry, power industry are generally used.The gasket seal majority often used in existing market and production is asbestos pad.The asbestos gasket sealing effectiveness is poor, and work-ing life is short, and running cost is high, and asbestos are a kind of carcinogenic substances, and each state all substitutes asbestos in research with novel material at present.
Silicon rubber is that a kind of molecular chain has inorganic and macromolecular material organic nature concurrently, has excellent resistant of high or low temperature, anti-ozone and weathering resistance, good electrical insulating property, water-repellancy, and nontoxic pollution-free.The outstanding performance of silicon rubber is the use temperature broadness, can be at-60 ℃ to+250 ℃ lower life-time service.Silicon rubber is widely as cable material, bio-medical material, aerospace material and sealing material at present.But the mechanical properties such as the tearing toughness of silicon rubber and tensile strength are poor, and acid-proof alkaline is not good enough, make it should not be in high strength, under the condition of soda acid as the used for sealing gasket material.Therefore need to make it have high anti-tearing strength and tensile strength, the performances such as acid and alkali-resistance to the silicon rubber modification.
Silicon rubber and plastic blend and silicon rubber and blend rubber are the important method that makes up the Silicone Rubber deficiency.Terpolymer EP rubber has good resistance to acids and bases, and Low Density Polyethylene has the mechanical properties such as good tensile strength and tearing toughness.In silicon rubber, adding at present terpolymer EP rubber and Low Density Polyethylene improves the acid-proof alkaline of silicon rubber and tearing toughness and tensile strength and makes it as at high-intensity acid-base condition lower seal pad, yet there are no report with silicon rubber.
CN102977605A discloses a kind of silicone rubber crosslinking fire-resistant cable material, raw material by following weight part is made: 100 parts, silicon rubber, terpolymer EP rubber 20-30 part, chlorinatedpolyethylene 8-10 part, Shawinigan black 15-20 part, dimethyl silicone oil 0.5-1.0 part, dicumyl peroxide DCP0.2-0.5 part, high density polyethylene(HDPE) 20-30 part, Calucium Silicate powder 15-25 part, modification potter's clay 0.5-1.0 part, precipitated silica 30-40 part, silane coupling agent KH5601-3 part, anti-aging agent 40400.2-0.5 part, Vulcanization accelerator TMTD 0.5-1.5 part, vulcanizing agent BP0.2-0.5 part, tribasic lead sulfate 2-4 part, antimonous oxide 12-15 part, zinc borate 6-8 part.
Summary of the invention
The invention provides a kind of rubber combination, to solve existing silastic product acid-proof alkaline, tensile strength and the poor problem of tearing toughness.
A kind of rubber combination, in weight part, comprising:
Described base rubber is comprised of the Low Density Polyethylene of 60-90 part methyl vinyl silicone rubber, 5-20 part terpolymer EP rubber and 5-20 part.
The high mechanical strength character of the acid resistance of terpolymer EP rubber and Low Density Polyethylene can be improved the deficiency of methyl vinyl silicone rubber aspect acid and alkali-resistance and physical strength, but consider the consistency of raw material, the content proportioning of each component should reach suitable ratio.
Preferably, the vinyl molecular fraction of described methyl vinyl silicone rubber is 0.05-0.5%.
Preferably, the 3rd monomer of described terpolymer EP rubber is that dicyclopentadiene or 5-ethylidene-2-norborneol are rare, and the mass percent of the 3rd monomer is 1.0-3.0%.
β-dimethyl-aminoethylmethacrylate, as the phase solvent of methyl vinyl silicone rubber and Low Density Polyethylene, can strengthen the blend between silicon rubber and plastics, is preferably 1-1.5 part.
Hydroxy silicon oil is a kind of constitution controller, can reduce rubber hardness, improves and the fracture extensibility, is preferably 1-2 part.
Containing hydrogen silicone oil is a kind of anti-yellowing dose, can be that silicon rubber is non-yellowing, is preferably 1-2 part.
Zinic stearas is a kind of lubricant, helps the demoulding, is preferably 1-2 part.
White carbon black is silicon rubber to be had to the filler of best reinforcing effect, can increase silicon rubber hardness and tensile strength, and along with the increase of specific surface area, elongation at break can descend to some extent, and preferred, the specific surface area of white carbon black is 200-250m
2/ g, described white carbon black is preferably 20-30 part.
Add silane coupling agent can strengthen common molten between silicon rubber and rubber, described silane coupling agent is preferably vinyl silicane coupling agent, vinyl silicane coupling agent can react and combination with organism, have and can be combined with inorganic material chemistry, the ability that can be combined with organic chemical material again, its consumption is more elected 2-3 part as.
Described vinyl silane coupling agent is preferably a kind of in vinyl three ('beta '-methoxy oxyethyl group) silane, vinyltriacetoxy silane, vinyltriethoxysilane, vinyl three tert.-butoxy silane.
Described vulcanizing agent is preferably organo-peroxide, and more preferably 2,5-dimethyl-2,5-bis-(t-butyl peroxy) hexane or bis(2，4-dichlorobenzoyl)peroxide, be preferably 2-3 part.
