Abstract
The invention relates to a method for reinforcing performance of a tread rubber of a lorry tyre by resin acceptor modified white carbon black, belonging to the technical field of nanometer material modified rubber process. The method comprises the following steps that: nanometer white carbon black is dried to remove moisture in vacuum at 120 DEG C, and is subjected to surface treating of a resin acceptor, wherein the dosage of the resin acceptor is 1 to 10 percent of the nanometer white carbon black powder by weight; on the basis of maintaining the prior production formula and the production flow of rubber, the nanometer white carbon black composite powder modified by the resin acceptor with 20 to 30 percent of unvulcanized rubber by weight is added in the process of mixing rubber. Testing results prove that after addition of the composite nanometer white carbon black, the tread rubber of the lorry tyre is greatly improved in tensile strength, tearing strength, hardness and the like.
Description
Technical field
The present invention relates to the method for reinforcing performance of tread rubber of lorry tyre by resin acceptor modified white carbon black, belong to nano material modified rubber Technology field.
Background technology
Tire occupies crucial status in each parts of automobile, every rideability of automobile is had great influence.Rubber tyre in use exposes short, wear resistance and the tire of shortcoming, especially cargo truck such as tearing toughness is relatively poor in work-ing life, and is limited in one's ability because of bearing a heavy burden, and often blows out.Therefore require the anti-cutting of tread rubber of lorry tyre by resin material, antifatigue, wear-resisting, hardness is high, distortion is little, it is hot low etc. to give birth to.Along with improving constantly that the tread rubber of lorry tyre by resin product performance are required, the performance that how further to improve tread rubber of lorry tyre by resin is the key subjects of pendulum in the current techniques field.
The technical development of novel nano-material provides new way for exploitation high-performance lorry tyre tread material.Utilize high dispersancy nano powder body material and rubber mix, on common mixing roll, carry out mixing, reinforced rubber.Novel inorganic nano-powder material commonly used at present comprises: nanometer alumina powder, calcium carbonate nano powder, barium sulphate nano powder etc.Chinese patent CN1168392A has reported diene rubber composition the application in tire make of aluminum oxide as reinforcing filler; Patent CN1598155 has reported and has added the ageing-resistant performance that nano-calcium carbonate can improve rubber; Patent CN1896130A has reported that a kind of admixture nanometer natural barite powder improves the method for rubber abrasive-resistance.
But consistency is poor between general nano-powder and rubber molecule, is difficult to disperse in organic phase, and particle tends to cohesion, makes the Rubber processing degradation.Therefore,, increase the interaction between the interface, adopt surface-modifying agent that nano-powder is carried out modification usually in order to improve the consistency between nano-powder and the rubber.
Summary of the invention
The object of the invention is to provide a kind of method that the method that Nano carbon white strengthens tread rubber of lorry tyre by resin, the particularly Nano carbon white after the coupling agent surface treatment strengthen tread rubber of lorry tyre by resin of mixing.
In order to achieve the above object, the present invention adopts following technical proposals:
A kind of method of reinforcing performance of tread rubber of lorry tyre by resin acceptor modified white carbon black is characterized in that this method has following technological process and step:
A. at first selecting median size for use is the 20nm Nano carbon white, through 120 ℃ of vacuum-drying 4h, removes its contained humidity as far as possible;
B. above-mentioned Nano carbon white powder is carried out organic surface treatment, surface treatment agent is that coupling agent comprises: γ-methacryloxypropyl trimethoxy silane (KH570), γ-(2,3-epoxy third oxygen) propyl trimethoxy silicane (KH560), two (triethoxysilylpropyl) tetrasulfide (Si69), contain a kind of in bifunctional (carboxyl and two build) the polymer-type coupling agent (C800); The consumption of coupling agent is a Nano carbon white powder weight 1%～10%; Adopt the dry method surface treatment, with coupling agent with alcohol dilution after, spray on the white carbon black powder, in the low speed kneader, mix then, obtain the Nano carbon white composite granule that modified surface is handled;
C. in rubber mixing process, add through coupling agent modified back Nano carbon white composite granule, add-on is 20%～30% of rubber (natural rubber) weight, obtains rubber through abundant after mixing, again through sulfidization molding, makes tread rubber of lorry tyre by resin.
Because nanoparticle has small-size effect and surface effects, after it is distributed in the rubber matrix with between rubber polymer, form stronger combining, lump together Reinforced Rubber firmly with polymer scale.In addition,, improve the consistency between nanoparticle and the polymkeric substance, increase the interaction between the interface, improve the mechanical property of rubber polymer by nanoparticle is carried out organic surface treatment.Therefore, Nano carbon white powder through coupling agent modified adds in the rubber and goes, and makes rubber have very high compactness, improve the mechanical property such as tensile strength, tear strength of tread rubber of lorry tyre by resin, had advantages such as low-rolling-resistance, high-wearing feature, wet-sliding resistant performance be good.
