Abstract
The invention relates to a preservative material of a preservative technology for manufacturing rubber tires. A preservative isolation layer capable of being circularly used for manufacturing rubber tires is composed of two layers of polyolefin surface layers and one layer of a synthetic-made woven wire mesh between the two layers of polyolefin surface layers; the polyolefin surface layers are prepared through a tape casting method; and preservative material is prepared by hot-pressing and compounding the synthetic-made woven wire mesh and the polyolefin surface layers at one time while the polyolefin surface layers are cured. Wire bundles of the synthetic-made woven wire mesh (3) are processed into strands or twisted to threads. The preservative isolation layer with the synthetic-made woven wire mesh is high in tensile strength and has the advantage that the hot-pressed and cured preservative isolation layer is firm in structure and unlikely to stretch, deform or damage. The thickness of the preservative isolation layer is between 0.2mm to 1mm.
Description
Technical field
The present invention relates to rubber tyre and make the employed Perserving materials of middle antistaling process, specifically be meant the structure that can be recycled in the fresh-keeping separation layer of rubber for tire sheet.
Background technology
Rubber tyre is to be formed by the hot pressing of several layers sheet rubber; In the manufacture craft of rubber tyre; Sheet rubber needs and air insulated, avoids sheet rubber and air, other gases to contact with foreign material oxidation and pollution take place, and existing sheet rubber is with the fresh-keeping isolation of polyethylene film.At sheet rubber hot pressing compound tense, the task of polyethylene preservative film is accomplished and is abandoned it.The polyethylene preservative film can only disposable reason be, when polyethylene preservative film and sheet rubber were peeled off, because the inherent characteristic of antistaling film, phenomenons such as distortion, fold, perforation can appear in the polyethylene preservative film.
Chinese patent " a CN02266375.4 reusable plasticizing type isolation liner (pad) cloth " discloses and has comprised that polypropylene woven cloth is basic framework, is coated with smooth smooth polyethylene or polypropylene or polyethylene and polypropylene compound film at the one or both sides of the basic skeleton of polypropylene woven cloth.It mainly contains following shortcoming: 1, polypropylene woven cloth cost is high; 2, spraying polyethylene or polypropylene material are difficult to bonding on polypropylene woven cloth; 3, with polypropylene woven cloth as skeleton, behind the spraying polyethylene, the out-of-flatness of isolation liner (pad) cloth; 4, complex process can not one-shot forming, and production cost is high.Up to the present fail to form and produce in batches, do not adopt in the production technology of existing tyre industry.
Summary of the invention
The present invention is directed to above-mentioned defective, a kind of new fresh-keeping separation layer that is used for the rubber tyre manufacturing capable of circulation is provided.Its product structure is simple and practical, and manufacturing approach is easy, controlled, thereby greatly reduces the production cost of tire manufacturing, possesses remarkable economic efficiency.
The fresh-keeping separation layer that is used for the rubber tyre manufacturing capable of circulation of the present invention is by two-layer TPO surface layer; One deck is positioned at the chemical fibre class braiding silk screen in the middle of the two-layer TPO surface layer; The TPO surface layer adopts salivation method to be equipped with, and simultaneously chemical fibre class braiding silk screen disposal solidifying is composited in the hot pressing of TPO surface layer.The effect of chemical fibre class braiding silk screen is equivalent to the steel bars in concrete structure.The chemical fibre tow can become thigh to be woven into silk screen, and tow also can be twisted into line.The material of TPO surface layer can mainly select for use TPO maybe can make the other materials of film according to the needs of tire manufacturing.The material of chemical fibre class braiding silk screen is mainly selected glass fibre, carbon fiber, aramid fiber, boron fibre and polyolefin high score subclass tow for use.Behind the compound chemical fibre class braiding silk screen, strengthen fresh-keeping separation layer hot strength, reduced fresh-keeping separation layer percentage elongation.Fresh-keeping separation layer thickness is between 0.2 millimeter to 1 millimeter.Fresh-keeping separation layer is in rubber tyre manufacturing process; With fresh-keeping separation layer together with sheet rubber rolling simultaneously; When two-layer sheet rubber is bonding; Fresh-keeping separation layer and rubber for tire sheet are peeled off, and the fresh-keeping separation layer of peeling off can be reused in next time owing to there is the support of chemical fibre class braiding silk screen to be difficult for stretching, distortion or damaged.
The advantage of fresh-keeping separation layer of the present invention is: owing to have chemical fibre class braiding silk screen in the middle of the two-layer TPO surface layer, fresh-keeping separation layer both softness can curl, and has tensile strength to be difficult for characteristics such as fold, distortion, perforation again.If tyre production enterprise can be saved original use disposable polyethylene preservative film expense nearly 2/3rds after using the fresh-keeping separation layer of the present invention.Be a kind of convenience, practicality, improve the fresh-keeping separation layer of tire workmanship and efficient.
Description of drawings
Fig. 1, structural representation of the present invention;
Fig. 2, embodiments of the invention midship section sketch map.
Specific embodiment
Below in conjunction with the description of drawings embodiments of the invention.
Embodiment 1
The material that TPO surface layer 1,2 of the present invention is selected for use is a polyethylene, and chemical fibre class braiding silk screen 3 materials are glass fibre or aramid fiber or boron fibre or polyphosphazene polymer alkene strand material.
Embodiment 2
The polypropylene of TPO surface layer 1,2 material selections of the present invention, chemical fibre class braiding silk screen 3 materials are glass fibre or aramid fiber or boron fibre or high-molecular polythene strand material.
Embodiment 3
TPO surface layer 1,2 of the present invention one side at least has embossing 4; Pressure roller shows that face is carved with colored shape; TPO surface layer 1,2 hot-press solidifyings and with middle chemical fibre class braiding silk screen 3 compound in, flower shape pressure roller is pressed into embossing face with TPO surface layer 1,2.Effect after the fresh-keeping separation layer embossing is to reduce the contact area of fresh-keeping separation layer and sheet rubber, is convenient to peeling off of sheet rubber and fresh-keeping separation layer.If the 1 one side embossing 4 of TPO surface layer, then the thickness of embossing surface layer 1 is slightly thicker than TPO surface layer plane layer 3.Behind the thickness of the thickness of embossing surface layer 1 greater than plane surface layer 3 one side, chemical fibre class braiding silk screen can all be covered by in the TPO surface layer 1,2.
The fresh-keeping barrier film of technique scheme manufacturing is being peeled off with the rubber for tire sheet; The fresh-keeping separation layer of peeling off is owing to there is the support fixation of chemical fibre class braiding silk screen; And each silk screen grid constitutes stable skeleton; Fresh-keeping separation layer is vertical or horizontal all being difficult for stretching, be out of shape or breakage, can recycle.
