Abstract
The invention relates to the field of rubber techniques, and in particular relates to a modified rubber containing rubber composition for pneumatic tyres. The rubber composition is characterized in that through taking 100 parts by weight of rubber component as reference, the rubber composition also comprises 60 parts by weight of carbon black or silica or a mixture of the two in arbitrary proportion, 0.5-5 parts by weight of zinc oxide, 0.5-5 parts by weight of a stearic acid, 0.5-5 parts by weight of sulfur, 0.5-5 parts by weight of an accelerator, and 5-30 parts by weight of sulfhydryl end-capped siloxane (which can be prepared by reacting halogenated siloxane with hydrosulfides), or 5-30 parts by weight of sulfhydryl end-capped polysiloxane (which can be prepared by reacting halogenated silane end-capped polysiloxane with hydrosulfides) or 5-30 parts by weight of sulfhydryl end-capped polyamide (which can be prepared by reacting halogen atom end-capped polyamide with hydrosulfides), wherein the rubber component is a mixture of one or two or three of natural rubber, butylbenzene rubber and butadiene rubber in arbitrary proportion.
Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of pneumatic tyre rubber combination that contains modified rubber.
Background technology
As everyone knows, wear-resisting, anti-slippery and low roll the resistance be high-performance tire prerequisite three big characteristics.But because the structural limitations of material itself, it is very difficult reaching above three kinds of performances on the material property simultaneously.Want to solve the problem of " devil's triangle " that tyre industry exists, need carry out new structure design or chemical modification current material.The molecular chain modification of rubber has epoxidation modification and halogenation modification etc.These modified-reactions need carry out in solvent with rubber latex, and prepared modified rubber can be used for compounding rubber.The direct method of using the functionalization monomer to carry out modification is less in rubber mixing process.Silicone compounds such as Si-69 that wherein is applied and Si-75 along with the application of WHITE CARBON BLACK in mixing process with rubber molecular chain and WHITE CARBON BLACK acting in conjunction, promptly belong to graft modification to rubber molecular chain.Gained cross-linked rubber mechanical property is lower, prepared tire wear, anti-slippery and low to roll resistive ability relatively poor.
Summary of the invention
The object of the invention is exactly in order to overcome the deficiency of above-mentioned prior art, a kind of pneumatic tyre rubber combination that contains modified rubber to be provided, and the gained cross-linked rubber has higher mechanical properties, and prepared tire has higher wear-resisting, anti-slippery and lowly roll resistive ability.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of pneumatic tyre rubber combination that contains modified rubber,
Rubber components with 100 weight parts is a benchmark, also comprises
The carbon black or silicon-dioxide or the arbitrary proportion mixture of the two that also comprise 60 weight parts,
0.5～5 part by weight of zinc oxide,
0.5～5 weight part Triple Pressed Stearic Acid,
0.5～5 weight part sulphur,
0.5～5 weight part promotor,
5～30 parts of end capped siloxanes of sulfydryl, wherein the end capped silane of sulfydryl can be by halo siloxanes and sulphur hydrogen salt prepared in reaction; Perhaps 5～30 parts of end capped ZGK 5 of sulfydryl, ZGK 5 can be by end capped ZGK 5 of halogenated silanes and sulphur hydrogen salt prepared in reaction; Perhaps 5～30 parts of end capped polymeric amide of sulfydryl, wherein the end capped polymeric amide of sulfydryl can be by end capped polymeric amide of halogen atom and sulphur hydrogen salt prepared in reaction;
Wherein said rubber components is a kind of in tree elastomer, styrene-butadiene rubber(SBR), the cis-1,4-polybutadiene rubber or the arbitrary proportion mixture of two kinds or three kinds wherein.
The invention has the beneficial effects as follows; Use end capped compound of sulfydryl and polymkeric substance and rubber is carried out the modification of mix stage; Modified effect is good, and to the not influence of existing production technique, prepared rubber unvulcanizate has higher wear resisting property, wet-sliding resistant performance and hangs down and roll resistive ability.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
