Abstract
The present invention provides a fire-retardant and wear-resisting rubber composition, prepared by the following raw materials: 100 parts by weight of acrylonitrile-butadiene rubber, 40 parts by weight of N220 carbon black, 10 parts by weight of N330 carbon black, 20 parts by weight of dioctyl phthalate, 0.8 to 1 part by weight of sulphur, 0.8 to 1 part by weight of dicumyl peroxide, 3 to 3.5 parts by weight of promoter, 3 to 3.5 parts by weight of flowable agent, 5 to 6 parts by weight of zinc oxide, 3.5 to 4 parts by weight of antiager, 4 to 5 parts by weight of crack-preventing agent, 8 to 10 parts by weight of defoaming agent, 3 to 5 parts by weight of musk xylene, 30 to 40 parts by weight of fire retardant and 2 to 4 parts by weight of 2% water emulsified organosilicon mold lubricant. Characteristics of the rubber composition: formula is more reasonable; the rubber composition is not easy to foam in processing, with certain fragrant smell radiated, and sealing and wear-resisting performances are good.
Description
Technical field
The present invention relates to a kind of rubber combination, especially relate to a kind of rubber combination with flame-proof abrasion-resistant performance.
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, it mainly is the manufacturing processed finished product surface foaming easily of this rubber combination in the production process, and said composition has pungent odour after long term high temperature uses, in addition, this patent also have one comparatively significant disadvantages be that flame retardant properties is relatively poor, use in some special fields to be restricted.
Summary of the invention
Problem to be solved by this invention provide a kind of have be difficult for to bubble the man-hour of adding and distribute certain aromatic odour, and the good rubber combination of sealing wear resisting property.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of flame-proof abrasion-resistant rubber combination, be prepared from by following raw materials according: paracril 100 weight parts, N220 carbon black 40 weight parts, N330 carbon black 10 weight parts, dibutyl ester 20 weight parts, sulphur 0.8～1 weight part, dicumyl peroxide 0.8～1 weight part, promotor 3～3.5 weight parts, flowing agent 3～3.5 weight parts, zinc oxide 5～6 weight parts, anti-aging agent 3.5～4 weight parts, be full of cracks prevents agent 4～5 weight parts, defoamer 8～10 weight parts, musk xylene 3～5 weight parts, fire retardant 30～40 weight parts, 2% aqueous emulsion organosilicone mold releasing agent, 2～4 weight parts.
As a further improvement on the present invention, the antimonous oxide that also contains 10～15 weight parts in the flame-proof abrasion-resistant rubber combination.
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.Add appropriate amount of defoamer, can avoid that rubber item bubbles when high temperature vulcanized, make the appearance impression of finished product of this rubber combination better; Add concentration and be 2.5% aqueous emulsion organosilicone mold releasing agent and help the stripping result of rubber finished product, can reduce the surface damage of finished product, increase the surperficial impression of finished product; Musk xylene is a kind of of synthetic musk, and fusing point is 113 degrees centigrade, can increase the aromatic odour of building rubber compound finished products, hides the pungent odour that said composition uses the back to produce at long term high temperature to a certain extent.That adds that rubber flame-retarded dose and antimonous oxide help promoting said composition puts out flame retardant properties certainly.
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, sealing all promote to some extent, finished product take place to bubble influences the number of times of appearance impression than not reducing by 40～50% before the adjustment prescription, and flame retardant properties is than not promoted 60～80% before the adjustment.
