Abstract
The invention provides a manufacturing method of a high abrasion-resistance rubber composition, which comprises the step of: mixing the following components in parts by weight through an open mill at 50+/-5 DEG C: 100 to 105 parts of raw rubber, 10 to 15 parts of N220 carbon black, 50 to 55 parts of N330 carbon black, 3 to 5 parts of nano-zinc oxide, 1.8 to 2 parts of anti-aging agent, 1.3 to 1.6 parts of vulcanizing agent, 4.5 to 6 parts of softening agent and 4 to 5.2 parts of crack preventing agent. The rubber composition has the characteristics of more reasonable formula, excellent tensile property and abrasion resistance and low possibility of cracking after long-term use.
Description
Technical field
The present invention relates to a kind of manufacture method of rubber combination, especially relate to a kind of manufacture method with rubber combination of better wear-resisting tensile property.
Background technology
Prescription and manufacture method about rubber combination are thousands of, often are furnished with different material prescriptions according to different service requirementss.In some special industries and special field,, tend to the rubber combination of these parts is proposed special requirement for improving the total quality of certain parts of making by rubber.For example in order to improve the quality of motorcycle cushion collar, the rubber mass that often requires to make it has stronger anti-pulling-out force.And various technology and the rubber compounding announced in the present technology, often not as meeting the demands, for example they are not that stretching resistance makes that inadequately the life-span of product is shorter, and ageing-resistant exactly ability influences the product phase behind the product life-time service inadequately, or technology is made complexity, manufacturing cost is higher.At present unique in the prior art possess the rubber compounding that can satisfy this special product material requirement of motorcycle cushion collar and be: rubber 100 weight parts, N330 carbon black 60 weight parts, anti-aging agent 2 weight parts, vulcanizing agent 1.5 weight parts, tenderizer 6.3 weight parts, and by mill mixing forming under 50～70 ℃ roller temperature.This technology has effect preferably in actual production, but also fails to reach best, awaits further improving.
On the basis of this technology, the inventor once applied for " a kind of manufacture method of rubber combination " patent of invention, and this technology has effect preferably in actual production, but also failed to reach best, awaited further improving.It is characterized in that rubber 100～105 weight parts, N220 carbon black 10～15 weight parts, N330 carbon black 50～55 weight parts, anti-aging agent 1.8～2 weight parts, vulcanizing agent 1.3～1.6 weight parts, tenderizer 4.5～6 weight parts, be full of cracks are prevented agent 4～5.2 weight parts, by mill mixing forming under 50 ± 5 ℃ roller temperature.According to said method produce, resulting rubber combination has good tensile property and is difficult for be full of cracks.But at the production field of some high-grade professional motorcycle cushion collars, it is not enough that the over-all properties such as wear-resisting of described rubber item still shows.
Summary of the invention
Problem to be solved by this invention provides a kind of good tensile property, remarkable wear resisting property and is difficult for the rubber combination of be full of cracks.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of manufacture method of high wear-resistant rubber composition, rubber 100～105 weight parts, N220 carbon black 10～15 weight parts, N330 carbon black 50～55 weight parts, nano zine oxide 2.5～3.5 weight parts, anti-aging agent 1.8～2 weight parts, vulcanizing agent 1.3～1.6 weight parts, tenderizer 4.5～6 weight parts, be full of cracks are prevented agent 4～5.2 weight parts, by mill mixing forming under 50 ± 5 ℃ roller temperature.
As a further improvement on the present invention, preferred plan of the present invention is: rubber 100 weight parts, N220 carbon black 12 weight parts, N330 carbon black 53 weight parts, nano zine oxide 3.2 weight parts, anti-aging agent 1.9 weight parts, vulcanizing agent 1.4 weight parts, tenderizer 5 weight parts, be full of cracks prevent agent 4.2 weight parts, by mill mixing forming under 52 ℃ roller temperature.
Adopt above technical scheme, compare with existing common rubber combination, remarkable advantage of the present invention is:
1, prescription is more reasonable.Adjustment by proportioning, because carbon black can not only improve the intensity of rubber item, and gives rubber item with good abrasion performance, tear-resistant, heat-resisting, oil resistant, prolong the work-ing life of goods, through test of many times, change whole N 330 carbon blacks into a certain proportion of N220 carbon black and N 330 carbon blacks; Because B10 has the composition of the carbon number distribution of broad and very rational straight-chain paraffin and isoparaffin, in very wide temperature range, can both play protective effect to the ozone-induced cracking of rubber item, rationally used the be full of cracks of certain part by weight to prevent that agent B10 from can form the physical protection film at product surface, prevented that effectively be full of cracks from producing; In this component, add other auxiliary agents such as flowing agent of appropriate amount, under the prerequisite of the over-all properties that does not influence component, also help to improve complete processing.Original technology with me is compared, and the present invention has also added nano zine oxide.Because nano zine oxide can be realized combining on the molecular level with rubber molecule, thereby can improve properties of rubber, use nano zine oxide can significantly improve an index such as heat conductivility, wear resisting property, tear resistance, tensile strength of product, and its consumption can be saved 35-50%, greatly reduces product cost; On complete processing, can prolong the sizing material time of scorch, very favourable to complete processing.The interpolation of nano zine oxide can also prolong the work-ing life of goods greatly, and can improve their outward appearance and color and luster, it is used for transparent or the colored rubber goods, there is the irreplaceable effect of traditional promoting agent such as carbon black to need for the wear resistance of improving product and sealing effectiveness good effect is arranged also in the goods such as airtight sealing, gasket.
2, over-all properties is obviously improved.By the synthesis measuring to embodiment, the present invention has further improved the tensile strength of rubber combination by reform and adjustment to relevant prescription.Original technology is promptly: rubber 100 weight parts, N330 carbon black 60 weight parts, anti-aging agent 2 weight parts, vulcanizing agent 1.5 weight parts, tenderizer 6.3 weight parts, by mill mixing forming under 50～70 ℃ roller temperature, the tensile strength of its prepared rubber combination only is 25KN.And the present invention is by the adjustment to kind of carbon black and weight part, by adding the improvement that be full of cracks prevents the improvement of agent and an amount of prescriptions such as flowing agent and adjusts the technologies such as roller temperature when mixing, make the anti-intensity of drawing of the prepared rubber combination of the present invention reach 35KN, and the finished product life-time service is difficult for be full of cracks.
