Description

The tinted rubber composition

Technical field

The present invention relates to a kind of rubber combination, especially relate to a kind of rubber combination with good light brightness.

Background technology

Prescription and manufacture method about rubber combination are thousands of, often are furnished with different material prescriptions according to different service requirementss.Common general component with the wear resisting property of anti-marquis commonly used at present is paracril 100, N330 carbon black 65, dibutylester 20, sulphur 1.8, promotor 2.5, flowing agent 2, anti-aging agent 4, zinc oxide 5, paraffin 1.5-2.5.Also having a kind of composition is paracril 100, N330 carbon black 35, N220 carbon black 30, dibutylester 20, sulphur 0.5, dicumyl peroxide 3, promotor 1.5, flowing agent 2, anti-aging agent 4, zinc oxide 5, paraffin 1.5-2.5.The rubber item quality that these two kinds of components are made is lower, not weather-proof, without low with, subduing property of antifatigue, easily be full of cracks, reliability is good inadequately when being used for dust prevention of vibration absorber.

Applied in person before this that a kind of name was called the patent of invention of special wear-resisting rubber composite, its main technical schemes is prepared from by following raw materials according for this rubber combination, paracril 105 weight parts, N220 carbon black 55 weight parts, N330 carbon black 15 weight parts, dibutyl ester 30 weight parts, sulphur 0.8～1 weight part, dicumyl peroxide 0.8～1 weight part, promotor 2 weight parts, flowing agent 2.1 weight parts, zinc oxide 5 weight parts, anti-aging agent 3.5～4.5 weight parts, be full of cracks prevents agent 4～5.2 weight parts.This technology has effect preferably in actual production, but still also exist certain limitation, the hardness, tensile strength, the abrasive wear resistance that mainly are reflected in said composition do not reach the best applications state as yet, the elasticity, flexibility, the toughness that are used to add man-hour are also obviously not enough, and product appearance light attractive in appearance inadequately, be difficult to satisfy the production requirement of high-grade rubber item.

Summary of the invention

Problem to be solved by this invention provides a kind of rubber combination with well wear-resisting, oil resistant, elasticity, toughness and black good brightness.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of tinted rubber composition, be prepared from by following raw materials according: paracril 105 weight parts, N220 carbon black 50 weight parts, N330 carbon black 10 weight parts, dibutyl ester 28 weight parts, sulphur 0.8～1 weight part, dicumyl peroxide 0.8～1 weight part, promotor 2 weight parts, flowing agent 2.1 weight parts, zinc oxide 5 weight parts, anti-aging agent 3.5～4.5 weight parts, be full of cracks prevents agent 4～5.2 weight parts, liquid softener 9～12 weight parts, Semen Lini oil 6～8 weight parts, nigrosine 0.8～1.2 weight part, 2% aqueous emulsion organosilicone mold releasing agent, 4 weight parts.

As a further improvement on the present invention, also can in said components, add the N of 0.8～1.2 weight part again, N ' diphenyl-para-phenylene diamine.

Adopt above technical scheme, compare with existing common rubber combination, remarkable advantage of the present invention is:

1, prescription is more reasonable.By the adjustment of proportioning, use original dibutylester instead dibutyl ester, molecular weight is bigger; System has adjusted the consumption of dicumyl peroxide, having broken through must be by a little sulphur and a large amount of mutually crosslinked technical limitation of superoxide in traditional rubber process prescription, and the collaborative crosslinked finished product ozone resistance that makes this component make of the sulphur of basic identical deal and superoxide obviously strengthens; Because carbon black can not only improve the intensity of rubber item, and give rubber item with good abrasion performance, tear-resistant, heat-resisting, oil resistant, prolong the work-ing life of goods,, change whole N330 carbon blacks into a certain proportion of N220 carbon black and N330 carbon black through test of many times; 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.Annex solution body rubber tenderizer then helps increasing the elasticity of composition.N, N ' diphenyl-para-phenylene diamine is as the general anti-aging agent of rubber, have good anti-flex crack and dynamic fatigue property, heat, oxygen, ozone, photoaging all there is certain barrier propterty, but consumption Gao Shiyi causes bloom, so in this component, selected a small amount of use, in component, add the N of 0.6～0.8 weight part, the performances such as the anti-ozone of goods that N ' diphenyl-para-phenylene diamine makes this component make are better.Can obviously promote the luminance brightness that goods become and add Semen Lini oil with nigrosine.Add concentration and be 2% aqueous emulsion organosilicone mold releasing agent and help the stripping result of rubber finished product, reduce the surface damage of finished product.

2, over-all properties is obviously improved.By synthesis measuring to embodiment, the present invention is by reform and adjustment to relevant prescription, than the General Purpose Rubber composition of similar prescription performances such as abrasion performance, tear-resistant, heat-resisting, oil resistant, ageing-resistant and elasticity all promote to some extent, its luminance brightness is also high by 10～20% than similar General Purpose Rubber composition
