Description
Technical Field
The invention relates to the technical field of rubber, in particular to high-temperature and low-temperature resistant anti-aging chloroprene rubber.
Background
In the existing rubber materials, the silicone rubber with excellent high and low temperature performance has low mechanical property and large bonding difficulty, and the application range of the silicone rubber is limited; the existing other rubber materials in the market have poor wide-temperature-range adaptability, such as the shear modulus is rapidly increased due to low-temperature crystallization hardening, and the high-temperature thermal stability is reduced, so that the use requirement of the wide-temperature range cannot be met. The Tg of the butadiene isoprene rubber can reach minus 104 ℃, the cold resistance is close to that of silicon rubber, and the mechanical property is superior to that of the silicon rubber.
With the rapid development of civil aviation industry in China, the demand of civil aviation sealing elements is more and more large, and higher and more rigorous requirements are provided for the use conditions of rubber sealing products, the civil aviation gasket and the sealing products requiring impact load resistance can work in various oil environments such as kerosene, gasoline, transformer oil, lubricating oil, hydraulic oil and instrument oil, the requirement of the working environment temperature is wider (-50 ~ 130 ℃), the use temperature in the air environment is-30 ~ 100 ℃, and weather resistance, ozone aging resistance and flame retardance are required.
The published patent No. CN201610057364.2 discloses a high and low temperature resistant nitrile rubber, which is prepared by blending nitrile rubber with high acrylonitrile content and ethylene propylene rubber, and simultaneously adopts ethylene-vinyl acetate rubber, ethylene acrylate rubber and the like as compatibilizers of NBR/EPDM blended rubber; adding methacrylate, and crosslinking with various rubbers under a peroxide vulcanization system to form an interpenetrating network, so that the physical and mechanical properties of the blended rubber are improved; the carbon nano tube is added to enhance and improve the combination effect of phase interfaces in a plurality of systems; the liquid ethylene propylene rubber is adopted as a softening agent, so that the high-temperature and low-temperature resistant rubber can resist high and low temperatures, can improve the processing performance of rubber materials, and can participate in crosslinking. Although the oil resistance and high temperature resistance of the rubber are improved, the nitrile rubber in the patent has poor low temperature resistance and high preparation cost. The overall resistance to high and low temperatures is poor. Chloroprene rubber is widely applied in the technical field of automobile production due to better mechanical properties, but chloroprene rubber in the prior art has limited low-temperature resistance, cannot be normally used under low-temperature conditions, and is easy to age when used at higher temperature.
Disclosure of Invention
In view of the above, the high and low temperature resistant anti-aging chloroprene rubber has high and low temperature resistant and anti-aging characteristics.
The invention relates to high-temperature and low-temperature resistant anti-aging chloroprene rubber which comprises the following components in parts by weight: 45-53 parts of chloroprene rubber, 5-8 parts of butyl rubber, 4-6 parts of polyether type polyurethane rubber, 4-5.4 parts of light magnesium oxide, 5-6 parts of white carbon black, 26-31 parts of carbon black, 6-8.5 parts of plasticizer, 3-4.6 parts of octylated diphenylamine, 1-2.3 parts of cyclohexyl thiophthalimide, 0.8-1.4 parts of zinc oxide, 0.5-0.8 part of tetramethyl thiuram disulfide and 0.6-1.1 parts of ethylene thiourea.
Preferably, the paint comprises the following components in parts by weight: 50 parts of chloroprene rubber, 6 parts of butyl rubber, 5 parts of polyether urethane rubber, 5 parts of light magnesium oxide, 5.5 parts of white carbon black, 28 parts of carbon black, 7 parts of plasticizer, 4 parts of octylated diphenylamine, 2 parts of cyclohexylthiophthalimide, 1 part of zinc oxide, 0.6 part of tetramethyl thiuram disulfide, 0.8 part of ethylene thiourea and 40MSF (homogenizing agent).
Ethylene thiourea as an accelerator, tetramethylthiuram disulfide as a second accelerator was used in combination with ethylene thiourea as an accelerator for the continuous vulcanizate. The homogenizing agent 40MSF is a commercially available homogenizing agent.
Wherein the chloroprene rubber is sulfur-modified chloroprene rubber.
Chloroprene rubber has better heat resistance and oxidation resistance than natural rubber, and the chloroprene rubber can be crystallized under the induction of strain to well improve the service life of the rubber, so related products of the chloroprene rubber have better fatigue resistance, and the cost can be greatly reduced by taking the chloroprene rubber as a raw material. The chloroprene rubber used is sulfur-modified chloroprene rubber, and the sulfur-modified chloroprene rubber is supplemented with white carbon black and carbon black filler for reinforcement, so that the tear resistance of the prepared rubber can be improved. The sulfur-containing chloroprene rubber has good high and low temperature resistance.
In the rubber system, a mode of compounding a plurality of rubbers is adopted, and the chloroprene rubber, the butyl rubber and the polyether type polyurethane rubber are blended, so that the glass transition temperature of the chloroprene rubber can be reduced, and the cold resistance of the rubber can be improved. The butyl rubber has good air tightness, can resist heat, ozone, aging and chemicals, and has shock absorption and electrical insulation properties. The butyl rubber has good resistance to sunlight and ozone, can be exposed to animal or vegetable oil or oxidizable chemicals, has low glass transition temperature, has a spiral structure of butyl rubber molecular chains, has more methyl groups, but every pair of methyl groups scattered on two sides of the spiral are staggered at an angle, so the butyl rubber molecular chains are still quite gentle, the glass transition temperature is low, and the elasticity is good. The high degree of saturation of the butyl rubber molecular chain makes it highly resistant to ozone and weathering. The ozone resistance is about better than that of natural rubber and is 10 times of that of styrene butadiene rubber. The highly saturated structure of butyl rubber makes it more chemically invariant. Butyl rubber has superior corrosion resistance to most inorganic and organic acids. The polyether type polyurethane rubber has excellent aging resistance, and the aging resistance of the whole rubber can be improved by blending the polyether type polyurethane rubber with chloroprene rubber.
The chloroprene rubber contains chlorine atoms, has good flame retardance and has good aging resistance. The neoprene has good crystallinity, does not slide between molecules under the action of strong external force at higher temperature, and has good high-temperature resistance.
The chloroprene rubber has high glass transition temperature, so that the low-temperature resistance of the chloroprene rubber is poor, and the glass transition temperature is reduced by blending.
The plasticizer is a substance capable of increasing the plasticity of a polymer compound or a polymer material. The plasticizing effect of the plasticizer is that the molecules of the plasticizer are inserted between molecular chains of the high molecular polymer, so that the attractive force between the molecular chains of the polymer is weakened, namely the aggregation effect between the molecular chains is weakened, the mobility and the flexibility of the molecular chains are increased, and the plasticity is increased. For example, the plasticizer can comprise 1-2.5 parts of rapeseed oil and 5-6 parts of dioctyl sebacate by weight.
The light magnesium oxide, octylated diphenylamine, cyclohexylthiophthalimide, zinc oxide and the like are used as an anti-aging system to improve the anti-aging performance of the rubber.
White carbon black, also known as silica, improves strength and increases adhesion of the sizing to the steel cord. It can also reduce heat generation and improve aging resistance. The carbon black also belongs to the pigment which mainly plays the roles of filling, dyeing and reinforcing. The proper addition of carbon black can improve the low temperature resistance of the rubber and make up for the defect that the chloroprene rubber has good high temperature resistance but limited low temperature resistance. The particle size of the carbon black is 30-40 nm. The white carbon black and the carbon black are used in a composite way, and the amount of the white carbon black is less, so that the mechanical property of the final rubber material can be ensured.
According to the application, butyl rubber and polyether type polyurethane rubber are added into chloroprene rubber to reduce the glass transition temperature of a final rubber product and improve the low-temperature resistance of the final rubber product, light magnesium oxide, octylated diphenylamine and cyclohexylthio-phthalimide in an anti-aging system can effectively improve the anti-aging capacity of the rubber, and meanwhile, the chloroprene rubber is used as base rubber and simultaneously supplemented with a reinforcing material compounded by white carbon black and carbon black to ensure the mechanical property of the rubber of the whole system.
