Abstract
The invention discloses a kind of preparation methods for injecting pu tire to preheat the specific steps are will uniformly smear release agent in mold to mold, and wire loop is fixed by the magnetic element that mould inside is arranged in framework material, completes the positioned internal of framework material.Magnetisable material is added in framework material, forms tension with mold magnetic element and completes framework material setting positioning.It is injected into tire-mold after rubber elastomer is heated, fills mold pressure-maintaining and heat-preservation and take out mold after a certain period of time, the made coating got tire substrate ready and apply one layer of thermoplastic film or anti-puncture in liner layer obtains pu tire.After tire used abrasion, the elastomeric material completion reparation that surface applies one layer of composite white carbon black can be carried out.Present invention process is simple, and gained pu tire wearability is good and fuel-economizing, surface coating layer can be repaired immediately, realizes tire long-life purpose, economizes on resources, environmental protection.
Description
Technical field
The present invention relates to a kind of preparation methods for injecting pu tire, are mainly used in and prepare pu tire.
Background technique
Polyurethane elastomer, for manufacturing the raw material of tire, has the history of decades as a kind of.It is poly- according to structure
Urethane tire is broadly divided into full-polyurethane elastomeric tire and polyurethane elastomer tyre surface/rubber tyre body composite tyre (polyurethane
Rubber composite tyre), both structure tires are required to solve the problems, such as that there is also difference.
The performance change of polyurethane is very big, can be plastics, rubber (elastomer) or fiber, can also be used to manufacture artificial
Leather.By oligomer polyol, polyisocyanates and chain extender can synthesize casting type, thermoplastics type, mixed milling type, reaction injection type and
The elastomer of 5 seed type such as solution dispersing type, wherein most importantly casting type, thermoplastics type and mixed milling type.It is different types of poly-
Urethane rubber is slightly different in performance, but in general, and polyurethane rubber has superior resistance to other rubber phase ratios
Grind performance.
Traditional cross-ply and radial tyre production process are more, equipment is more, energy consumption is high, therefore, seek a kind of new life
Production. art substitutes traditional handicraft, simplifies production process, reduces equipment, reduces energy consumption, becomes tyre industry and be devoted for years in solution
A big project.
Polyurethane (PU) elastomer has elastic higher, wear-resisting property excellent (can be 2~10 times of NR) and oil resistivity
Can, the features such as ozone resistance and cryogenic property are good.It is using the polyurethane elastomers such as cast PU elastomer manufacture tire
The most fundamental approach of tyre forming process is reformed, complicated solid phase processing can be made to be changed to simple liquid phase processing, eliminated huge
Production equipment, enormously simplify processing technology, make material mixing, molding, vulcanization realize integration.These of PU elastomer are special
Point becomes the hot spot of domestic and international tire industry concern.
But in the forming processes such as injection, casting, the framework materials such as required wire loop are difficult to accomplish fixed in tire
Position.External PU tire research work starting is more early, and LIM company of the U.S. etc. proposes the tyre bead portion for 2 wire loops being mounted in mold
On, the PU elastomer for injecting high stress at definite elongation refills tread mould around upper belt after die sinking, injects the PU of low stress at definite elongation
Elastomer finally forms and tire is made.Although used technique for traditional technique, is simplified and convenient,
But equally exist the problems such as wire loop positioning is difficult, cumbersome.
The purpose that the application proposes is in order to solve the problems such as positioning of pu tire wire loop is difficult, using magnetic orientation by steel
Wire ring and the fixed method in a mold of framework material, molding mode complete the system of pu tire using injection molding method
It is standby, the cumbersome technique of traditional radial-ply tyre and bias tire is enormously simplified, it can be achieved that automated production, improves production efficiency.
Summary of the invention
The invention discloses a kind of preparation methods for injecting pu tire, de- the specific steps are will uniformly smear in mold
Mould agent, preheats mold, and wire loop is fixed by the magnetic element that mould inside is arranged in framework material, completes framework material
Positioned internal.Magnetisable material is added in framework material, after leaching adhesive is pre-processed, is formed with mold magnetic element
Tension completes framework material setting positioning.It is injected into tire-mold after polyurethane is heated, fills mold pressure-maintaining and heat-preservation one
Mold is taken out after fixing time, made tire substrate of getting ready can be in liner layer one layer of thermoplastic film of coating or the coating of anti-puncture.Wheel
After tire is using abrasion, the elastomeric material completion reparation that surface applies one layer of composite white carbon black can be carried out.Tire substrate is with poly- ammonia
Ester elastomer is matrix injection material, and tyre framework material is by being shaped by magnetic force and positions in a mold, and injection moulding obtains tire.
Specifically includes the following steps: a kind of preparation method for being injection moulded pu tire, it is characterised in that: with polyurethane
Elastomer is that matrix prepares tyre injection material, and tyre framework material is by being shaped by magnetic force and positions in a mold, is injection moulded
To tire.Specifically includes the following steps:
