Abstract
The invention discloses a wear-resistant rubber composition for an automobile dust shield. The wear-resistant rubber composition for the automobile dust shield of the invention comprises, by weight, 100 parts of chloroprene rubber, 2 parts of a mold cleaner 985P, 2 parts of an antioxidant A, 1 part of an antioxidant RD, 1 part of an antioxidant MB, 1 part of stearic acid, 3 parts of high molecular wax, 5 parts of magnesium oxide, 4 parts of a petroleum resin, 3 parts of a moisture absorber, 25 parts of carbon black N330, 30 parts of fast extruding furnace black, 15 parts of dioctyl sebacate, 15 parts of rape seed oil, 0.5 parts of sulfur, 5 parts of zinc oxide and 1 part of a promoter NA-22. The wear resistance of the improved dust shield is near four times the wear resistance of original dust shields.
Description
Technical field
The present invention relates to the automobile component field of rubber materials, more particularly, relate to a kind of wear-resistant type rubber combination that is used for vehicle dust protector.
Background technology
Dw in use can not be avoided the phase mutual friction between the crest, and friction may cause dw to break, and railway grease overflows, and dw lost efficacy.Improve the dw wear resisting property and crucial effect is arranged for improving vehicle safety performance.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that exists in the prior art, and a kind of wear-resistant type rubber combination that is used for vehicle dust protector is provided.
The present invention is used for the wear-resistant type rubber combination of vehicle dust protector, is become by following components in weight portion array: 100 parts of X 050s, mould must 2 parts of happy 985P, 2 parts of antioxidant As, 1 part of anti-aging agent RD, 1 part of anti-old MB, 1 part of Triple Pressed Stearic Acid, 3 parts of macromolecule wax, 5 parts in Natural manganese dioxide, 4 parts of petroleum resin, 3 parts of moisture adsorbents, carbon black N33025 part, extrude carbon black N55030 part, 15 parts of dioctyl sebacates, 15 parts of Uni Ace Rs, 0.5 part in sulphur, 5 parts in zinc oxide, accelerant N A-221 part soon.
Dw after the present invention improves has improved nearly 4 times than former dw wear resistance, improves the result in order to verify wear resistance, tests as follows:
Condition 1: universal joint pivot angle 40 degree, rotating speed 600rpm carries out the wear-resisting experiment of normal temperature fixed angle, and test-results is following:
Before not improving: dw all broke in 4 hours;
Improve the back: dw broke in 15 hours.
Condition 2: universal joint pivot angle 44 degree, the same experiment table of rotating speed 600rpm carries out the wear-resisting experiment of normal temperature fixed angle, test-results:
Before not improving: dw all broke in 2.5 hours;
Improve the back: dw broke in 11 hours.
By above interpretation; Dw after the improvement has improved nearly 4 times than former dw wear resistance, because the test employing is that fixedly wide-angle is wear-resisting, condition is so harsh in actual the use; Dw can not be in maximum angle all the time; The friction durability of therefore improving the back dw can be according to the road examination experiment life estimate of former dw, and its life-span is at least former dw life-span * 4 times, and it is apparent in view to improve effect.
Embodiment
In the face of doing, the present invention further describes down.
The present invention is used for the wear-resistant type rubber combination of vehicle dust protector, is become by following components in weight portion array: 100 parts of X 050s, mould must 2 parts of happy 985P, 2 parts of antioxidant As, 1 part of anti-aging agent RD, 1 part of anti-old MB, 1 part of Triple Pressed Stearic Acid, 3 parts of macromolecule wax, 5 parts in Natural manganese dioxide, 4 parts of petroleum resin, 3 parts of moisture adsorbents, carbon black N33025 part, extrude carbon black N55030 part, 15 parts of dioctyl sebacates, 15 parts of Uni Ace Rs, 0.5 part in sulphur, 5 parts in zinc oxide, accelerant N A-221 part soon.
Above-mentioned materials is mixed with Banbury mixer and mill according to aforementioned proportion sequentially.Mix the back rubber unvulcanizate and use water cooling, store after 24 hours, use rubber injection moulding machine under 160 ℃ of high temperature, to make its sulfidization molding in mould.Take out the preparation of promptly accomplishing vehicle dust protector after cooling off.
Following table is that the wear-resistant type rubber combination of vehicle dust protector improves the physicals of front and back and the data contrast of low temperature torsion test.
Embodiment recited above describes the preferred embodiment for the present invention; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention; Common engineering technical personnel make technical scheme of the present invention in this area various distortion and improvement all should belong to protection scope of the present invention.
