Problems solved by technology

Then if the stress relaxation phenomenon is not controlled, when the rubber is cut to a fixed length, the stress relaxation process is still not over and will continue, resulting in the shortening of the length of the rubber after the fixed-length cutting in the subsequent processing process, affecting the finished product of the sealing strip The size of the sealing strip material between the two corners is too short to meet the assembly of the whole vehicle, resulting in a large amount of scrap

Abstract

The invention discloses an automobile door glass guide groove seal bar adhesive material and applications thereof. Crude adhesive with high mooney viscosity and low ethylene content is adopted as a main raw material; a great quantity of high-structure fillers and high-flash-point paroline are added, and semi-effective vulcanized system vulcanized by sulphur is matched, so that the heated contraction rate of seal bar materials is controlled to be within 1%. The conventional physical performance of seal bars can meet the performance requirement of automobile door glass guide groove seal bars on materials, and the secondary baking step required in the subsequent process of the existing seal bars is omitted, so that energy sources are saved, and the waste caused by scrappage for poor size is eradicated. The adhesive material provided by the invention is used for preparing the automobile door glass guide groove seal bars, and is further applied to automobile doors and automobiles.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a rubber material for a glass run groove sealing strip of an automobile door and an application thereof. Background technique [0002] The car door glass guide channel is an essential component of the car window glass and its lifting system. The difference in the structure of different parts of the gold leads to the changeable material structure of different sections of the glass run channel of the car door. It is necessary to use the joint sealing strip glue to bond the materials of different sections, and the wear resistance of the surface directly affects the lift of the window glass. For smoothness, in order to improve wear resistance, spray coating is applied to the corner surface after joining. [0003] In the prior art, the production process of the glass run channel of the automobile door includes: extrusion→vulcanization→spraying→curing→cooling→rough cutting→...
