Abstract
The utility model relates to a tire retreading technique, more particularly for solving the problem of difficult joint connection of composite tire surface during retreading of strip-shaped polyurethane-rubber composite pre-vulcanized tire surface by using different joint shapes. When the two end faces of the strip-shaped polyurethane-rubber composite pre-vulcanized tire surface are connected with each other to form a ring shape, the connection portion is a joint, which has such a shape that both the polyurethane crown (1) and the rubber base adhesive (2) are vertical straight surface or inclined surface with respect to a used tire body, or that the polyurethane crown (1) is a straight surface with respect to the used tire body and the rubber base adhesive (2) is an inclined surface with respect to the used tire body. When the joint has a shape of the inclined surface, the inclined surface preferably has an angle of 40-50 DEG. The utility model can not only simply the production process and greatly improve the joint quality but also improve the production efficiency and reduce the production cost, thereby completely solving the problem of difficult joint connection of composite tire surface and facilitating the generalization and application of the green and environment-friendly product with high performance-to-price ratio.
Description
Technical field
The utility model relates to tyre retreading technique, specifically is meant the problem of compound tread joint difficulty when adopting different joint geometries to solve bar shaped polyester-rubber composite procuring tread retreads.
Background technology
At present the reconditioning technology of old tire turns over (adopt mould high temperature vulcanized) by traditional heat and develops into comparatively advanced cold the turning over of technology (adopting natural gum low temperature precured tread technology), and more environmental protection, more energy-conservation, polyurethane-General Purpose Rubber composite procuring tread reconditioning technology that cost performance is higher.
Rubber precured tread retreads joint is simple, only needs the rubber adhesion face polish, cleaned out, is coated with rubber cement, pastes adhesive glue, docks then, blocks joint position (coming off when preventing to inflate) with the card pin and get final product, and joint is firm after vulcanizing.
Polyurethane-General Purpose Rubber composite procuring tread has annular and two kinds of bar shapeds at present.The annular compound tyre surface need not joint, can solve the joint problem, but owing to the tire physical dimension difference of each new tyre manufacturer design, its physical dimension of tire of same manufacturer production also have fluctuation, cause old carcass physical dimension fluctuation bigger, so to the equipment precision requirement height, investment is big, production efficiency is low, and to the bad adaptability of old carcass, even the also less employing of rubber precured tread.The compound tyre surface of bar shaped is good to the adaptability of old carcass, is not subjected to the influence of old carcass physical dimension fluctuation, and equipment investment is few, production efficiency is high; But because the poor adhesion between polyurethane and the half finished rubber, can only be bonding between polyurethane and the polyurethane with polyurethane, or with vulcanized behind the cast polyurethane of the base portion glue two sides of specially treated, with the polyurethane face bonding, and bond properties is poor at normal temperatures, so have the problem of joint difficulty, also do not have very ripe method to solve the joint problem of compound tyre surface at present.How to solve the problem of bar shaped composite procuring tread joint difficulty, become the bar shaped composite procuring tread can be in reconditioning technology the key of wide popularization and application.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, solve the problem of bar shaped polyester-rubber composite procuring tread joint difficulty, a kind of joint that can improve the retreads of joint quality with bar shaped polyester-rubber composite procuring tread greatly is provided.
The retreads of the utility model indication are made up of polyurethane crown glue and rubber base portion glue with bar shaped polyester-rubber composite procuring tread, joint when bar shaped polyester-rubber composite procuring tread two ends are connected into annular is a joint, and its joint geometry has two kinds: a kind ofly be the vertical inclined-plane of facing directly or be for the relative old carcass with rubber base portion glue of polyurethane crown glue; Another kind of for the old relatively carcass of polyurethane crown glue for face directly, the old relatively carcass of rubber base portion glue is the inclined-plane.
The bevel angle preferred value is 40～50 ° when its joint geometry is the inclined-plane.
The utility model compared with prior art has following advantage:
(1) adopts joint geometry of the present utility model, simplified production technology (as the processing, oven dry, the cast polyurethane that vulcanize adhesive glue surface, space, joint, back, be heating and curing, operation such as texturing line), can reduce manually, enhance productivity, reduce production costs.
(2) though increased splicer, can reduce the higher equipment of expense such as cast polyurethane, texturing, reduce equipment investment.
(3) can improve joint area peel strength, improve joint quality.
(4) thoroughly solve the problem of compound tread joint difficulty, helped applying of this high performance-price ratio of polyester-rubber composite procuring tread, Green Product.
Description of drawings
Fig. 1 is the vertical joint geometry schematic diagram of facing directly for the relative old carcass with rubber base portion glue of the utility model polyurethane crown glue;
Fig. 2 is the joint geometry schematic diagram on inclined-plane for the relative old carcass with rubber base portion glue of the utility model polyurethane crown glue;
Fig. 3 for the old relatively carcass of the utility model polyurethane crown glue for face directly, the old relatively carcass of rubber base portion glue is the joint geometry schematic diagram on inclined-plane.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment one:
As shown in Figure 1, present embodiment adopts the relative old carcass with rubber base portion glue of polyurethane crown glue to be the vertical joint of facing directly.Retreads are made up of polyurethane crown glue 1 and rubber base portion glue 2 with bar shaped polyester-rubber composite procuring tread, joint is meant bonding 3 of polyurethane, 5 and the joint of rubber base portion glue bond face 6,8, its shape is vertically to be faced directly, promptly adhesive tape cut the mouth be vertical.Concrete preparation method is as follows:
Step 1: make the joint that polyurethane crown glue and rubber base portion glue are the vertical plane shape
Method by Chinese patent application numbers 200610037107.9 makes bar shaped polyester-rubber composite procuring tread, vertically cuts bar shaped polyester-rubber composite procuring tread according to the outer perimeter of old carcass, makes its length meet the requirement of old carcass outer perimeter; The vertical adhesive surface 3 of polyurethane among shape such as Fig. 1 and 5, the vertical adhesive surface 6 of base portion glue and 8.
Step 2: bar shaped polyester-rubber composite procuring tread is docked
Earlier section rubber base portion glue bond face 6,8 is polished, and clean out, be coated with rubber cement; Bonding 3 of section polyurethane, 5 is cleaned out, parked 3min.
After the rubber cement of rubber base portion glue bond face 6,8 is done, paste the thick rubber adhesion glue 7 of 1.0mm at rubber base portion glue bond face 6, bonding 3 of polyurethane, 5 is coated with one deck polyurethane binder 4, the rubber base portion glue bond face 8 that does not paste rubber adhesion glue 7 is docked with the base portion glue bond face 6 that adhesive glue is arranged, note limit mouth alignment; Bonding 3 of polyurethane docks with 5, notices that groove and pattern block will adopt the splicer joint to prevent pattern dislocation to connecting, and splicer applies the pressure of 1.0MPa to compound tyre surface, with the joint compacting, bubble can not be arranged; With the card pin joint is blocked, prevent that the joint position from coming off; With cellophane tape surface, polyurethane joint is sealed, prevent that polyurethane binder heating back is mobile.
