Abstract
The present invention relates to compound tyre producing technology, and is especially one kind of compound polyurethane-rubber tyre and its production process. The compound polyurethane-rubber tyre has optimized and modified recipe of polyurethane of oligomer polyhydric alcohol/tetrafuran-propylene oxide copolymer-p-phenylenediisocyanate system and polyurethane of oligomer polyhydric alcohol/hydroxy-eliminated polybutadiene-diphynel methane diisocyanate system; tyre surface treatment; and casting to form the green tyre in compound structure. The compound tyre has less heat produced during running, high heat resistance, applicability to high speed running and long service life as well as simple production process and low cost.
Description
Technical field
The present invention relates to a kind of manufacturing technology of composite tyre, more specifically to a kind of polyurethane tread-rubber tyre body composite construction green tire and manufacture method thereof.
Background technology
Polyurethane is a kind of material of excellent combination property, the 60 years of development mileages of having passed by, has unique combination property: very wide hardness, intensity and modulus ranges, high elongation rate, wide serviceability temperature scope, and also have characteristics such as good oil resistant, low temperature resistant, anti-ozone aging, and premier wearability, be commonly called as " abrasive rubber ", its wearability is 2～10 times of natural rubber, and moulding process and equipment are simple, can recycle fully, are a kind of more satisfactory tire tread glue materials.
Since the sixties in last century, many in the world countries have just begun polyurethane is applied to the research work that tire is made, as Austrian lim company, the phoenix of Germany and the UTI company of Britain etc.These researchs structurally substantially all are polyurethane integral casting type tires, and promptly carcass and tyre surface all adopt the polyurethane manufacturing.During moulding cord, belt, wire loop etc. are located in mould in advance and put well, adopt then centrifugal casting method with cast polyurethane in mould, curing and demolding tire product.This integrated poured type polyurethane tire building is convenient, fast, and equipment cost is low, only is with 1/5th of scale rubber tyre investment of production equipment.But because polyurethane polarity is strong, intermolecular and the intramolecular hydrogen bond effect is big, cause its strand rigidity big, Nei Shengre is also very big under dynamic service condition, and the hear resistance of polyurethane own is poor, long-term serviceability temperature is below 80 ℃.Therefore these tires of developing only are adapted to the occasion that travel speed is lower than 50Km/ hour, as bicycle, RV, cut the low speed tire of usefulness such as careless car, Caddy, scooter etc.U.S. Amerityre company has developed the passenger vehicle spare tire recently, though reached the standard of the United States Federal's MotorVehicleSafetyStandard (FMVSS) 109, make the practicality of pu tire reach a new class, but this tire is the solid tyre of being made by the hole sealing polyurethane foam, still can only travel 2000 miles with 50Km/ hour speed.In sum, because the particularity of polyurethane material structural behaviour, the pu tire that emerges at present is the low speed tire.
Summary of the invention
The objective of the invention is to overcome the weak point of above-mentioned pu tire, adopt polyurethane tread-rubber tyre body composite construction, and polyurethane formulations is optimized and modification, it is travelled give birth to the low and hear resistance height of heat, run at high speed and require and the polyurethane-rubber composite tyre and simple, with low cost, the easy industrialized manufacture method of technology thereof of long service life thereby propose a kind of adaptation.
The present invention is achieved by following technical proposals.
The present invention includes following step and process conditions:
Step 1: the surface treatment of rubber tyre body
(1) preparation of surface conditioning agent:
With the N of 5～15 weight portions, N-dichloro-p-toluene sulfonamide is added in the anhydrous propanone solution of 85～95 weight portions that molecular sieve is handled, and adds the benzoyl peroxide of 3～10 weight portions after stirring and dissolving is even again, and stirring gets final product;
(2) preparation of polyurethane adhesive:
Earlier be that 1000～2000 polytetrahydrofuran diol or polycaprolactone glycol and the synthetic according to a conventional method isocyano-content of pure methyl diphenylene diisocyanate are the base polyurethane prepolymer for use as between 7～8% with molecular weight, being diluted to base polyurethane prepolymer for use as concentration with ethyl acetate then is 40～60%, re-use 1,4-butanediol/triethanolamine mixing chain extension;
(3) carcass process of surface treatment:
Bonding position polishing with rubber tyre body and polyurethane tread, clean out the surface conditioning agent that the back evenly sprayed or brushed step 1 (1) preparation, parked 0.5～1 hour, or carry out Surface Treatment with Plasma, parked 0.1～1 hour, evenly spray or brush the polyurethane adhesive of step 1 (2) preparation again, parked 0.5～3 hour, promptly can be used for pouring into a mould tyre surface;
Step 2: the preparation of polyurethane tread glue performed polymer system
(1) oligomer polyol/oxolane-expoxy propane copolyether-PPDI system polyurethane:
System is synthetic according to a conventional method, and wherein oligomer polyol is polytetrahydrofuran diol or the polycaprolactone glycol of molecular weight between 1000～2000; Oxolane-expoxy propane copolyether amount ranges oligomer polyol/oxolane-expoxy propane copolyether system total amount 30～50% between, wherein molecular weight is that 2000 expoxy propane content is 20～40%; Isocyano-content is between 3.5～5.0% in the performed polymer;
(2) oligomer polyol/end hydroxy butadiene-methyl diphenylene diisocyanate system polyurethane:
System is synthetic according to a conventional method, and wherein oligomer polyol is polytetrahydrofuran diol or the polycaprolactone glycol of molecular weight between 1000～2000; The end hydroxy butadiene amount ranges oligomer polyol/end hydroxy butadiene system total amount 15～30% between; Isocyano-content is between 5.0～7.0% in the performed polymer;
(3) preparation of modified crystal whiskers silicon:
After the powder silicon whisker heat-activated of 100 weight portions, add the polyisocyanates of 50～60 weight portions and the dry toluene of 150～250 weight portions, reacted 1～2 hour down at 80 ± 2 ℃, then 220～240 ℃ of temperature and overbottom pressure less than the vacuum of 500Pa under piptonychia benzene, dry 4～6 hours, cooling, pulverize the silicon whisker that promptly obtains modified polyisocyanate;
(4) preparation of nano imvite:
The imvite of 5～10 weight portions joins in the distilled water of 90～95 weight portions, 14～the OTAC that progressively adds 14～16 weight portions under 80 ± 2 ℃, stir reaction down 1～2 hour, obtain montmorillonite suspension liquid, suction filtration, be washed to no chlorion, drying is pulverized the Powdered nano imvite into about 50～90nm;
