Abstract

The utility model discloses a room temperature vulcanization bias tyre patch, which comprises an old tyre body line layer (3), the inner and outer surface of the old tyre body line layer (3) are respectively coated with high temperature vulcanization bonding mucilage layers (2), (4), the utility model is characterized in that the old tyre body line layer (3) is an arc shape, the high temperature vulcanization bonding mucilage layer (2) is also connected with the vulcanized rubber layer (1), the high temperature vulcanization bonding mucilage layer (4) is also connected with the vulcanized rubber layer (5), the outside of the vulcanized rubber layer (1) is connected with a room temperature vulcanization bond layer (6). The utility model can mend rather big gaps, and the mending effect is good without wearing the inner tube, and the utility model is easy to operate and has low cost.

Description

A kind of auto-vulcanization cross-ply sticking patch

(1) technical field: the utility model relates to a kind of tire sticking patch, relates in particular to a kind of auto-vulcanization cross-ply sticking patch.

(2) background technology: at present, conventional method is to the place under repair of cross-ply hard defects, generally use the line layer that strips down from the cutting of the carcass of waste and old cross-ply to make pad, starch at the pad double spread, spread the half finished rubber layer, stick on the wound of inside tires, add the airbag aeration pressurization in inside tires then, be put into again and carry out baking on the spot cure machine, pad and tire are combined as a whole, though this repair method pad is drawn materials cheaply, but there is following shortcoming: 1, because gasbag pressure is less, the nylon wire of rubber layer and pad the phenomenon of line layer often occurs exposing in conjunction with defective tightness, alice very easily presss from both sides the broken inner tube of a tyre, causes and repairs failure; 2, complicated operation is loaded down with trivial details, wastes time and energy.And the prevulcanization moulding on the large-tonnage vulcanizer of sticking patch employing cord fabric is repaired in a kind of auto-vulcanization that occurs in the market, and have the auto-vulcanization adhesive linkage, though rubber and line layer are in conjunction with tight, can naked wire, simple to operate, but because the restriction of technological level and mould, be flat shape sticking patch at present, and the shape of tire is an arc, thus can only repair minor cut or wound, and also cost is very high.

(3) summary of the invention: the purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of big wound of repairing is provided, and repair efficiency is good, and the inner tube of a tyre that can not wear and tear is simple to operate, the auto-vulcanization cross-ply sticking patch that cost is low.

The purpose of this utility model can reach by following measure: a kind of auto-vulcanization cross-ply sticking patch, it comprises old matrix line layer (3), the inside and outside two sides of old matrix line layer (3) scribbles high temperature vulcanized bonding mucilage layer (2), (4) respectively, it is characterized in that old matrix line layer (3) is an arc, high temperature vulcanized bonding mucilage layer (2) connects vulcanized rubber layer (1) again, high temperature vulcanized bonding mucilage layer (4) connects vulcanized rubber layer (5) again, the outer auto-vulcanization adhesive linkage (6) that connects of vulcanized rubber layer (1).

The utility model can produce following good effect compared with the prior art: because the utility model is in conjunction with above-mentioned two kinds of sticking patch advantages, it is the old matrix line layer that adopts from tire toe to the toe mouth, coat rubber cement, half finished rubber is spread on the two sides, be put in the special mould, on the large-tonnage vulcanizer, vulcanize and enclose one deck auto-vulcanization adhesive linkage, so it has the following advantages: 1, cover sulfuration glue-line and old matrix line layer in conjunction with closely, can not expose the line layer and the inner tube of a tyre that weares and teares by alice; 2, adopt arcuate structure, consistent with tire construction with tire is in conjunction with tightr, and area is big, can repair big wound, and repair efficiency is good; 3, skin has the auto-vulcanization adhesive linkage, and is simple to operate; 4, adopt old matrix line layer to make, cost is lower.

(4) description of drawings:

Accompanying drawing is a structural representation of the present utility model.

(5) specific embodiment: preferred forms of the present utility model is elaborated below in conjunction with accompanying drawing:

Embodiment: a kind of auto-vulcanization cross-ply sticking patch (referring to accompanying drawing), it comprises old matrix line layer 3, old matrix line layer 3 is an arc, its inside and outside two sides scribbles high temperature vulcanized

bonding mucilage layer

2,4 respectively, high temperature vulcanized bonding mucilage layer 2 connects vulcanized rubber layer 1 again, high temperature vulcanized bonding mucilage layer 4 connects vulcanized rubber layer 5 again, the vulcanized rubber layer 1 outer auto-vulcanization adhesive linkage 6 that connects.During use, polishing is cleaned to the tire wound earlier, filled rubber, and with the inside and outside baking that clamps of point type vulcanizer, tire internal wounds place corresponding site is cleaned in polishing then, coats the auto-vulcanization agent, pastes promptly inflatable use mutually with the auto-vulcanization adhesive linkage 6 of this product.

Claims

1, a kind of auto-vulcanization cross-ply sticking patch, it comprises old matrix line layer (3), the inside and outside two sides of old matrix line layer (3) scribbles high temperature vulcanized bonding mucilage layer (2), (4) respectively, it is characterized in that old matrix line layer (3) is an arc, high temperature vulcanized bonding mucilage layer (2) connects vulcanized rubber layer (1) again, high temperature vulcanized bonding mucilage layer (4) connects vulcanized rubber layer (5) again, the outer auto-vulcanization adhesive linkage (6) that connects of vulcanized rubber layer (1).
