Abstract
The invention relates to a preparation method of an additive for a steel wire radial tire and belongs to the technical field of a rubber additive. The preparation method comprises the following steps: S1, uniformly mixing 20-30 parts of resorcinol, 30-40 parts of hydroxyl nitrile rubber, 5-10 parts of polycarbonate resin, 3-6 parts of polytetrafluoroethylene and 3-8 parts of ethylene-vinyl acetate copolymer in a mixer to obtain a mixture; S2, adding 150-200 parts of a solvent into the mixture and then adding 4-8 parts of zinc borate, 2-4 parts of aluminum disulfide, 2-5 parts of magnesium borate, 20-30 parts of epoxy resin, 2-4 parts of dipentaerythritol and 10-15 parts of dispersant, maintaining for 2-4 hours and uniformly stirring. According to the reinforcement additive for the steel wire radial tire, the bonding force between the steel wire and the tire rubber can be remarkably improved.
Description
Technical field
The preparation method who the present invention relates to the additive that a kind of radial wire cord tire uses, belongs to rubber accelerator technical field.
Background technology
Radial, compared with common bias tyre, has many advantages.And give the basic reason of radial performance, be that radial is different from the structure of common bias tyre.Radial feature is: 1. the direction that plies cords is arranged is consistent with the meridian section of tire.Because cord is so arranged, its intensity is fully used.The general comparable common bias tire of curtain cloth layer of radial reduces approximately 40%～50%, and carcass is more soft.2. adopt belt, can bear the larger tangential force producing while travelling.Meridian mold has some layers of cord and meridian section to be the belt of the similar buffer layer of wide-angle (angle of cut is 70 degree～75 degree), high strength, the difficult circumferential annular stretching.Belt adopts the fabric cord that intensity is higher, tensile deformation is very little (as the high-strength material such as glass fibre, tynex) or wirecord fabric manufacture conventionally.The advantage of radial is: 1. contact area is large, and adhesion property is good, and tyre surface slippage is little, also little to ground unit pressure, thereby rolling resistance is little, long service life.2. crown is thicker and have hard belt, is difficult for piercing through; While travelling, be out of shape littlely, can reduce oil consumption 3%～8%.3. because curtain cloth layer is few, sidewall is thin, so radial elastic is large, shock-absorbing capacity is good, and portative power is larger.Shortcoming: 1) zone of transition on crown and sidewall easily produces breach.Thinner because of sidewall, crown is thicker.2) side distortion is large, causes the lateral stability of automobile poor, and manufacturing technology requires high, and cost is also high.
Radial manufacturing process is divided into: rubber is plasticated, mixing-tyre surface, sidewall manufacture-carcass, belt manufacture-various type glue component manufacture---tyre bead manufacture---production testing of tyre building---tyre sulfuration---cover tire finished product etc.
In prior art, by being the bonding force that need to add additive enhancing framework material and rubber in rubber.But, in many additives, contain heavy metal element, after tire is scrapped, these heavy metals can affect environment.
Summary of the invention
The object of the invention is: the enhancement additive that provides a kind of radial wire cord tire that does not contain heavy metal to use, technical scheme is:
A preparation method for the additive that radial wire cord tire is used, comprises the steps:
The 1st step, by weight, by 20～30 parts of Resorcinols, 30～40 parts of carboxylated nbrs, 5～10 parts of polycarbonate resins, 3～6 parts of tetrafluoroethylene, 3～8 parts of ethane-acetic acid ethyenyl resin copolymers, be placed in stirrer for mixing even, obtain mixture;
The 2nd step, 150～200 parts of solvents will be added in mixture, then add 4～8 parts of zinc borates, 2～4 parts, curing aluminium, 2～5 parts of magnesium borates, 20～30 parts of epoxy resin, 2～4 parts of Dipentaerythritols, 10～15 parts of dispersion agents, keep 2～4 hours, stir.
Preferably, described dispersion agent is selected from polyethylene wax, oxidized polyethlene wax, polyamide wax.
Preferably, described solvent is selected from dimethylbenzene, butylacetate, methyl acetate, ethyl acetate.
Preferably, described epoxy resin is epoxy resin E-44 or E-40.
