Abstract
The invention provides a patterned rubber sleeve for fabricating a transmission belt and a fabrication method thereof. The patterned rubber sleeve mainly comprises the following raw materials in parts by weight: 99-101 parts of butyl rubber, 3.5-4.5 parts of vulcanizing agent, 1-2 parts of tetramethyl disulfide, 0.5-1.5 parts of promoter, 44-46 parts of carbon black, 7.5-8.5 parts of paraffin oiland 4.5-5.5 parts of coumarone indene resin. The fabrication method of the patterned rubber sleeve comprises the following steps: mixing rubber; mould pressing; and jointing rubber films with clear vulcanized patterns through raw rubber to obtain the finished product of the patterned rubber sleeve. The patterned rubber sleeve and the fabrication method have the advantage that the patterned rubbersleeve replaces a steel die with engraved patterns, namely a reverse vulcanization molding process is adopted. The fabrication method has the beneficial effects of improving utilization ratio of the patterned rubber sleeve, simplifying fabrication procedures of the patterned rubber sleeve, reaching clear pattern effect, lowering cost, shortening pattern replacement cycle, greatly strengthening strain capacity of the product and meanwhile effectively improving qualification rate of the product.
Description
Technical field
The present invention relates to a kind of decorative pattern gum cover for making transmission belt and preparation method thereof.
Background technology
Existing a kind of application number is 200510067968.7 and is called that the Chinese invention patent of " transmission belt and manufacture method thereof " discloses a kind of structure, its structure is: a kind of method for preparing transmission belt comprises the steps: to stack gradually transmission belt back, pulling force supporting body layer, the first fiberless matrix film and the second matrix film that is filled with fiber and makes the transmission belt blank; With with forming method the transmission belt rib is molded in the transmission belt blank.The technique of this transmission belt carves decorative pattern at steel mould usually, adopts conventional multi-wedge band production technique to produce automobile multi-wedge belt again.Its shortcoming needs to drop into a large amount of pattern moulds because of the multi-wedge band specification more, and manufacture difficulty is high, and expense is large, must carefully protect the decorative pattern on the mould during use, otherwise affect product appearance because decorative pattern is impaired, reduces product percent of pass.
Summary of the invention
First technical problem to be solved by this invention is that the decorative pattern gum cover that is used for making transmission belt that a kind of utilization ratio is high, decorative pattern is clear, expense is low, the replacing decorative pattern cycle is short, product percent of pass is high is provided for above-mentioned prior art present situation.
Second technical problem to be solved by this invention is the making method that the decorative pattern gum cover that is used for the making transmission belt that a kind of technique is simple, decorative pattern is clear, expense is low, the replacing decorative pattern cycle is short, product percent of pass is high is provided for above-mentioned prior art present situation.
The present invention solves the technical scheme that above-mentioned first technical problem adopts: this decorative pattern gum cover: it is characterized in that: its prescription mainly is comprised of following raw material, 99～101 parts of isoprene-isobutylene rubbers, 3.5～4.5 parts of vulcanizing agents, 1～2 part of curing tetramethyl-, 0.5～1.5 part of promotor, 44～46 parts of carbon blacks, 7.5～8.5 parts of paraffin oils, Gu 4.5～5.5 parts of the grand resins of horse, above-mentioned is weight part.
As improvement, described vulcanizing agent can be preferably: dicumyl peroxide.
Improve, described promotor can be preferably: mercaptobenzothiazole again.
Improve, described prescription is again: 100 parts of isoprene-isobutylene rubbers, and 4 parts of vulcanizing agents, curing tetramethyl based 1.5 part, 1 part of promotor, 45 parts of carbon blacks, 8 parts of paraffin oils, solid horse is swelled 5 parts of resins, and above-mentioned is weight part.
The technical scheme that above-mentioned second technical problem of invention solution adopts is: the making method of this decorative pattern gum cover is characterized in that may further comprise the steps:
One, refining glue: the prescription requirement by claim 1 takes by weighing weight, prepare material, carry out mixingly in temperature is 79～81 ℃ milling machine again, mixing time is 3.8～4.2 minutes, then park after 23.8～24.2 hours to roll at press and film, the thickness of this film is 9～11mm;
Two, mold pressing: it is to vulcanize 49～51 minutes on 149～151 ℃ the pattern mould that film is placed on temperature, vulcanizes the film for rubber that clear decorative pattern;
Three, carry out the rubber joint with vulcanizing the film for rubber that clear decorative pattern, namely be made into the decorative pattern gum cover of finished product.
Improve, described press is three roll squeezers again.
Compared with prior art, its advantage of decorative pattern gum cover of the present invention and preparation method thereof is: adopt the decorative pattern gum cover to replace the steel mould of texturing line, namely adopt the technique of reverse-forming sulfuration; Technique of the present invention has not only improved the utilization ratio of decorative pattern gum cover, and has simplified the making of decorative pattern, and decorative pattern is clear, and expense is low, changes the decorative pattern cycle short, has greatly improved the product adaptability to changes, has effectively improved product percent of pass simultaneously.
