Abstract
The invention relates to the field of tire production manufacturing, and in particular, relates to a chopped carbon fiber-containing rubber composition for a tire side wall. The composition is formed by mixing the following components in parts by weight: 30-60 parts of natural rubber, 40-70 parts of synthetic rubber, 35-65 parts of a reinforcing agent, 2-10 parts of chopped carbon fibers, 0.5-3 parts of a vulcanizing agent, 0.5-5 parts of a vulcanization accelerator, 3-10 parts of a vulcanization activator, 2-8 parts of an anti-aging agent, and other auxiliary agents. A mixing method of the chopped carbon fiber-containing rubber composition for the tire side wall comprises the step of two-stage mixing.
Description
Technical field
The present invention relates to tire production and manufacture field, particularly relate to a kind of rubber composition for tire sidewall containing chopped carbon fiber.
Background technology
Carbon fiber (carbonfiber is called for short CF), is a kind of phosphorus content tencel material more than 95%.It not only has the intrinsic intrinsic property of material with carbon element, has both again the soft machinability of textile fabric, is a new generation's fortifying fibre.As the one of high-performance fiber, carbon fiber carbon material obtains extensive use in military and civilian industry every field, from civilian industries such as space flight, aviation, automobile, electronics, machinery, chemical industry, light textiles to sports equipment and leisure goods etc..Therefore, carbon fiber is considered as the Typical Representative of infant industry material in high-tech area, is attracted attention by common people.Chopped carbon fiber has lightweight, high-strength, Gao Mo, corrosion-resistant, conduction, advantages of good shielding performance, wave absorbtion high.Along with rapid development of economy, the excellent properties of chopped carbon fiber highlights day by day in the application of rubber materials.
External staple fibre strength rubber is carried out widely studied starts from the seventies in last century, has had bigger development to the eighties.In recent years, China has had more research in this respect.Chopped fiber is used for strengthening rubber as reinforcing agent, and its composite had both had the elasticity of rubber, maintained again the strength and stiffness of fiber, and goods have high intensity, high-modulus, the premium properties such as swelling tear-resistant, anti-.Chopped fiber can be directly added in rubber matrix after surface preparation as inorganic particulate filler, adopts suitable technique to carry out orientation and can obtain final products after blended.The reinforcing property of chopped fiber is good, even may replace conventional long fibre yarn fabric framework material within the specific limits, without complicated processing technique, thus can simplify production technology, improves the production automation and serialization degree.
Chopped carbon fiber is to be formed by carbon fiber filament chopped, and its key property depends primarily on the performance of its material carbon fiber filament.Due to floss that its mode of appearance is certain length must, relatively long filament, chopped carbon fiber has and is uniformly dispersed, and feeding manner is various, the simple advantage of technique, it is possible to be applied to the field that long filament can not be suitable for.
It is an object of the present invention to provide a kind of novel tire sidewall elastomeric material.Containing the tire sidewall glue that chopped carbon fiber compositions prepares, owing to chopped carbon fiber has the feature of high intensity, high-modulus, chopped carbon fiber can in the deformation of the same limit rubber matrix providing strengthening action, improve the stress at definite elongation of sidewall rubber material, it is possible to strengthen the anti-puncture ability of carcass.
Summary of the invention
The present invention relates to tire production and manufacture field, particularly relate to the rubber composition for tire sidewall containing chopped carbon fiber.Rubber composition for tire sidewall containing chopped carbon fiber, by following components, (number) is mixing by weight constitutes for said composition: natural rubber 30-60 part, synthetic rubber 40-70 part, reinforcing agent 35-65 part, chopped carbon fiber 2-10 part, vulcanizing agent 0.5-3 part, vulcanization accelerator 0.5-5 part, vulcanizing activator 3-10 part, age resistor 2-8 part, other auxiliary agent.
The present invention is containing the compounding process of chopped carbon fiber tire sidewall glue composition, including following two sections of mixing step:
(1) first paragraph is mixing: add natural rubber, synthetic rubber, mixing 0.5-1.5min at 40-90 DEG C, it is subsequently adding the mixing 1-5min of small powder such as chopped carbon fiber, zinc oxide, stearic acid, age resistor and antiscorching agent, add white carbon black and the mixing 2-5min of environment protection oil, clean 0.5-3min binder removal, dump temperature 140-180 DEG C；
(2) second segment is mixing: add one section of elastomeric compound and vulcanizing agent and vulcanization accelerator, thin logical 6 bottom sheet.Sizing material is 140 DEG C-175 DEG C at the curing temperature on vulcanizing press, and cure time is 15min-50min.
Matter feature and remarkable result that the reality that the present invention highlights prepares can emerge from from following embodiment, but they are not that the present invention does any restriction.
