Abstract
The present invention relates to a heat setting method for a rubber sealing strip bonded with a double-face adhesive tape, which comprises the process that the rubber sealing strip is heated and vulcanized by a mould, wherein the process that the rubber sealing strip is heated and vulcanized by a mould comprises the steps: the side face of the rubber sealing strip bonded with the double-face adhesive tape is thermally insulated from a heat conduction part of the mould, and the side face of the rubber sealing strip bonded with the double-face adhesive tape is cooled by a cooling device. The step that the side face of the rubber sealing strip bonded with the double-face adhesive tape is thermally insulated from the heat conduction part of the mould comprises a step that an insulating heat-insulation layer is arranged in the heat setting mould. The temperature of an isolation protective layer made from a plastic film on the rubber sealing strip is kept below the heat melting temperature of the isolation protective layer when the method of the present invention is used, the isolation protective layer made from the plastic film on the rubber sealing strip is not affected by heating in the process of heat setting heating and vulcanization, and the function of the isolation protective layer is kept.
Description
Technical field:
The present invention relates to the heat setting method of a kind of heat treatment method of rubber, particularly a kind of double-face adhensive tape rubber sealing strip.
Background technology:
In the prior art; the method of rubber seal strip adoption baking realizes typing; the temperature of baking of rubber weather strip that is used for automobile is between 150～250 degrees centigrade; be used for being stained with two-sided tape on a kind of rubber weather strip of automobile; before reality is used; with the isolated protective layer of a plastic sheeting system, the heat resisting temperature of the isolated protective layer of described plastic sheeting system is below 120 degrees centigrade on the adhesive tape.
Summary of the invention:
Technical problem to be solved by this invention is: because in the prior art; the method of rubber seal strip adoption baking realizes typing; the temperature of baking of rubber weather strip that is used for automobile is between 150～250 degrees centigrade; be used for being stained with two-sided tape on a kind of rubber weather strip of automobile; before reality is used; the isolated protective layer of having a plastic sheeting system on the adhesive tape; the heat resisting temperature of the isolated protective layer of described plastic sheeting system is below 120 degrees centigrade; so when pressurization of the hot joint of rubber weather strip and baking; stick to the isolated protective layer meeting melted by heating of the plastic sheeting system on the rubber weather strip; cause isolated protective layer to lose efficacy, so that influence the performance of final sealing strip product.The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind of heat setting method of double-face adhensive tape rubber sealing strip, comprise a process of described rubber weather strip being utilized the mold heated sulfuration in the heat setting method of described this double-face adhensive tape rubber sealing strip, wherein, in the described process of rubber weather strip being utilized mold heated sulfuration, comprise the step that the side of the double-face adhensive tape of described rubber weather strip and the heat-conduction part branch of mould are carried out the heat isolation, simultaneously, in the described process of rubber weather strip being utilized mold heated vulcanize, also comprise the process that cooling device cools off the side of the double-face adhensive tape of described rubber weather strip that adopts, particularly, the side of described double-face adhensive tape with rubber weather strip and the heat-conduction part branch of mould carry out the step that heat isolates can be realized by in the thermal finalization mould insulated thermal insulating layer being set, further, can will separate in the mold cavity plate that contact with the other parts of rubber weather strip except that the side of double-face adhensive tape from the thermal finalization mould with the mold cavity plate of the contacts side surfaces of the double-face adhensive tape of rubber weather strip in the thermal finalization mould, and in described separated place formation separation gap, simultaneously, can also in described separation gap, fill the heat-barrier material in the prior art, further, in described thermal finalization mould with the mold cavity plate portion of the contacts side surfaces of the double-face adhensive tape of rubber weather strip in, a cooling device can be set, particularly, described cooling device can utilize the cooling water that flows to realize the relative low temperature of aforementioned mold cavity plate portion through cooling water pipeline by a cooling water pipeline is set in aforementioned mold cavity plate portion.
The present invention contrasts prior art; because the heat-conduction part branch of the side of the double-face adhensive tape of described rubber weather strip and mould is carried out heat isolates; simultaneously; adopt a cooling device that the side of the double-face adhensive tape of described rubber weather strip is cooled off; so can make the temperature of the isolated protective layer of the plastic sheeting system on the rubber weather strip remain on it below heat fusing temperature; in the baking process of thermal finalization; the isolated protective layer of the plastic sheeting system on the rubber weather strip is not added heat affecting, keeps its function.
