Abstract
The invention discloses a formula of high-load and small-heat transfer deflection damping rubber. The formula comprises 70 parts of natural rubber, 30 parts of isoprene rubber, 30 parts of high wear resistant furnace black, 3 parts of coumarone resin, 1 part of a processing assistant, 1 part of an antiager RD, 5 parts of zinc oxide, 1 part of stearic acid, 1.5 parts of sulfur, 2 parts of a promoter DS and 0.8 parts of an anti-scorching agent. The formula of high-load and small-heat transfer deflection damping rubber satisfies wear resistance, high hardness, tensile strength and rubber quality and plastication process stabilization requirements.
Description
Technical field
The present invention relates to and measure less yielding rubber formula for high-load and heat deflection shape, belong to rubber compounding technical field.
Background technology
High-load and heat deflection shape measure the formula of less yielding rubber, have the requirement that it is special.Require that its wear resistant is excellent, hardness and tensile strength high, rubber quality and operation of plasticating stable.
Summary of the invention
For meeting above-mentioned requirements, the object of this invention is to provide and measure less yielding rubber formula for high-load and heat deflection shape, to make its product meet excellent wear resistant, high rigidity and tensile strength, the stable requirement of rubber quality and operation of plasticating.
For achieving the above object, the present invention is realized by following technique means:
Measure less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: comprise natural rubber 70 parts, synthetic polyisoprene 30 parts, high abrasion furnace black(HAF) 30 parts, coumarone indene resin 3 parts, processing aid 1 part, anti-aging agent RD 1 part, 5 parts, zinc oxide, stearic acid 1 part, Sulfur 1.5 parts, vulkacit D S2 part, scorch retarder 0.8 part.
Further:
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: the model of described natural rubber adopts RSS-3 natural rubber.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: described processing aid is the mixture of high molecular weight fatty acid ester and insoluble bulking agent.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: described vulkacit D S is 2-morpholine dithio-benzothiazole.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: the rubber content of described natural rubber is more than 50%.
Described for high-load and the less yielding rubber formula of heat deflection shape amount, it is characterized in that: the described product hardness obtained for high-load and the less yielding rubber formula of heat deflection shape amount is 70 °, and tensile strength is at 20 more than MPa.
The invention has the beneficial effects as follows: provided by the invention for high-load and the less yielding rubber formula of heat deflection shape amount, its product can be made to meet excellent wear resistant, high rigidity and tensile strength, the stable requirement of rubber quality and operation of plasticating.
Embodiment
Measure less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: comprise natural rubber 70 parts, synthetic polyisoprene 30 parts, high abrasion furnace black(HAF) 30 parts, coumarone indene resin 3 parts, processing aid 1 part, anti-aging agent RD 1 part, 5 parts, zinc oxide, stearic acid 1 part, Sulfur 1.5 parts, vulkacit D S2 part, scorch retarder 0.8 part.
Further:
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: the model of described natural rubber adopts RSS-3 natural rubber.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: described processing aid is the mixture of high molecular weight fatty acid ester and insoluble bulking agent.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: described vulkacit D S is 2-morpholine dithio-benzothiazole.
Described measures less yielding rubber formula for high-load and heat deflection shape, it is characterized in that: the rubber content of described natural rubber is more than 50%.
Described for high-load and the less yielding rubber formula of heat deflection shape amount, it is characterized in that: the described product hardness obtained for high-load and the less yielding rubber formula of heat deflection shape amount is 70 °, and tensile strength is at 20 more than MPa.
The present invention and synthetic rubber and object be the instability of fluctuation in order to reduce natural rubber quality and operation of plasticating.
Evaluated by actual tests, qualified can use but also should add flex fatig resistance anti-aging agent.If its surperficial major part of the rubber item used exposes to the open air under air, then can add 1 ~ 2 part of ozone-resistant anti-aging agent 3C.
People are thinner to using the consciousness of tenderizer (special hydrocarbon system process oil) in natural rubber.If must use, then preferably select ointment.When manufacturing high strength (weather resistance) rubber item with natural rubber, rubber content need more than 50%.This is because hardness reduces after adding tenderizer, for regulating hardness to need to add carbon black loading again, thus rubber content is caused to reduce.
Use coumarone indene resin and processing aid be in order to control carbon black mixing time heat-dissipating and improve that it is dispersed.
Incipient scorch is produced when scorch retarder Vulkalent AN is for preventing mixing.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
