Abstract
The utility model belongs to the technical field of automotive trims, and particularly relates to a colorful rubber composite doorframe sealing strip. Metal frame materials or reinforced fibers are arranged along the axial direction inside the inner portion of a rubber sealing strip body which is squeezed by ethylene-propylene-diene monomer (EPDM) dense rubber and EPDM sandwich rubber in a composite mode. The outer surface of the rubber sealing strip body is provided with a colorful thermoplastic elastomer (TPE) layer in a composite mode. The colorful rubber composite doorframe sealing strip has the advantages of being environment-friendly, wide in hardness range, good in dyeing property, soft in touch, weather-resistant, fatigue-resistant, thermal-resistant, good in processing property, free of being vulcanized, and capable of being recycled and reducing cost. The colorful TPE layer is refined by color master and colorless TPE in a proportioning mode, the color is identical with or similar to the colors of the automotive trims, and the appearance and the price of an automobile are improved overall.
Description
Technical field
The utility model belongs to weather strip for automobile extrusion technical field, refers in particular to a kind of colorful rubber combined door frame weather strip.
Background technology
Along with the development of auto manufacturing technology, to the demand of riding comfortable, attractive in appearance etc. the extension of automobile, lifting and require more and more higher to the globality of automobile.Automotive trim mostly is ecru, light blue, grey etc., traditional weather strip is black, for weakening the aberration of conventional black weather strip and interior trim, make environment inside car Total tune, comfortable, attractive in appearance, the appearance in the contact of the car body interior trim of doorframe class weather strip covers the colored EPDM rubber of one deck usually, and the color of this colorful rubber and interior trim color-match, coordination consist of globality.But because mainly there is following drawback in the colorful rubber production technology ": 1. adopt the color matching of EPDM rubber, complex process, the difficult control of operation, all there is aberration in the color that causes same color to refine out at different batches, is difficult to consistent, unified; 2. colored EPDM rubber because high temperature causes color decomposition easily, causes the color aberration after extruding sulfuration, is difficult to control to solid colour; 3. the colorful rubber that forms by the color matching of EPDM rubber is subjected to occur easily fading after the illumination, and illumination aging resisting performance is poor.Cause the more problems such as cost and quality.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of mixing color, color and luster stable homogeneous, and the good colorful rubber combined door frame weather strip of illumination aging resisting performance.
The purpose of this utility model is achieved in that a kind of rubber combined sealing strip for door frame, inside axis direction with the rubber weather strip body of the closely knit glue of EPDM and EPDM sandwich rubber compound extruded is provided with metallic framework material or fortifying fibre, and the external surface of rubber weather strip body is compounded with the colored TPE layer of one deck.
Above-mentioned metallic framework material is steel wire or steel belt framework.
Above-mentioned colored TPE layer is mouth mould place and this bluk recombination of rubber weather strip at extruder.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utlity model has environmental protection, characteristic that hardness range is wide, good coloring is arranged, soft-touch, weatherability, fatigue resistance and temperature tolerance, processing characteristics is superior, need not vulcanize, and can recycle, and reduces cost.
2, the utility model is at the mouth mould place of head, colored TPE layer is compounded in the EPDM weatherstrip body surface of black, the TPE layer forms by and the colourless TPE proportioning refining of look female, and it is identical with the automotive trim color or close to reach color, promotes on the whole the attractive in appearance and price of automobile.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Among the figure: 1, weatherstrip body; 2, metallic framework material;
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1;
A kind of colorful rubber combined door frame weather strip, inside axis direction with the rubber weather strip body 1 of the closely knit glue of EPDM and EPDM sandwich rubber compound extruded is provided with metallic framework material 2 or fortifying fibre, the external surface of rubber weather strip body is compounded with the colored TPE layer of one deck, utilize colored TPE layer to be coated on the EPDM surface of black, replace traditional black EPDM sizing material.
Above-mentioned metallic framework material is steel wire or steel belt framework.
Above-mentioned colored TPE layer is identical with the automotive trim color or close.
Above-mentioned colored TPE layer is mouth mould place and this bluk recombination of rubber weather strip at extruder.
The utlity model has environmental protection, characteristics that hardness range is wide, good coloring is arranged, soft-touch, weatherability, fatigue resistance and temperature tolerance, processing characteristics is superior, need not vulcanize, and recyclable the re-using of waste product that processing is scrapped is to reduce cost.
The principle of traditional colorful rubber combined door frame weather strip is: generally be with two kinds or the above closely knit glue of black EPDM or sandwich rubber and the synchronous compound extrudeds of framework material such as steel wire or steel band, and then compound with the EPDM sandwich rubber of black, the trim panel of the closely knit glue of the EPDM of its black and light color has a common boundary, visually give people's colour consistency poor, interior trim is of low grade, thereby affect the attractive in appearance of car load, therefore need colored EPDM rubber or the colored TPE layer that compound one deck is identical or close with the automotive trim color again on the closely knit glue of the EPDM of black surface.
Special TPE prescription and EPDM prescription guarantee that the variable color degree of the rear product of xenon lamp aging test can meet the requirement of standard code.
Colored TPE of the present utility model takes colourless TPE and look female color matching, and proportioning is simple, refining is simple, and the color matching of traditional EPDM elastomeric compound, to take Ethylene Propylene Terpolymer, multiple material and the look female mixing color matchings such as carbon black, fine particle calcium carbonate, proportioning is difficult to grasp, calendering process is complicated, causes aberration.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
