Abstract
The invention discloses a rubber sealing strip for an automobile and relates to the technical field of parts of the automobile. The rubber sealing strip is prepared from the following materials in parts by weight: 80-100 parts of ethylene-propylene-diene rubber, 4-8 parts of dicumyl peroxide, 2-4 parts of triallyl isocyanurate, 0.4-0.8 part of promoter, 60-80 parts of carbon black, 13-17 parts of softening agent and 1.3-1.5 parts of anti-aging agent. Compared with the prior art, the rubber sealing strip disclosed by the invention has the advantages of small permanent compression deformation, better aging performance and good processing safety.
Description
Technical field
The present invention relates to technical field of automobile, especially a kind of Rubber Seal Strip for Automobile.
Background technology
Rubber weather strip is mainly used in the fields such as automobile, machinery, door and window, rubber weather strip for automobile is applied to the positions such as car door, vehicle window, vehicle body, seat, skylight, engine case and boot, plays and fills gap, sealing, vibration damping, makes up the effects such as assembling error.Rubber Seal Strip for Automobile easily deforms and the phenomenon such as aging in life-time service process, these phenomenons have had a strong impact on the sealing property of sealed strip, damping property and work-ing life, affect in the index of the above-mentioned performance of sealed strip various, above-mentioned use properties important indicator is the most intuitively weighed in compression set, the shape and size that it mainly involves rubber item are stablized, in order to obtain the reliability of long term seal, there is strict requirement to the compression set of weather strip for automobile sizing material.But the compression set rate of existing Rubber Seal Strip for Automobile is undesirable, in order to reduce tension set, applicant is devoted to improve from aspects such as formula, manufacturing process automobile rubber weather strip.
Summary of the invention
The object of this invention is to provide a kind of Rubber Seal Strip for Automobile, this sealed strip can solve the higher problem of the compression set of rubber weather strip.
In order to solve the problem, the technical solution used in the present invention is: this Rubber Seal Strip for Automobile is made up of the raw material of following parts by weight: terpolymer EP rubber 80 ~ 100 parts, dicumyl peroxide 4 ~ 8 parts, cyanacrylate 2 ~ 4 parts, promotor 0.4 ~ 0.8 part, carbon black 60 ~ 80 parts, tenderizer 13 ~ 17 parts, 1.3 ~ 1.5 parts, anti-aging agent.
In the technical scheme of above-mentioned Rubber Seal Strip for Automobile, technical scheme can also be more specifically: terpolymer EP rubber 100 parts, dicumyl peroxide 5 parts, cyanacrylate 2 parts, promotor 0.5 part, carbon black 60 parts, tenderizer 15 parts, 1.5 parts, anti-aging agent.
Further, described carbon black is spray carbon black.
Further, described promotor is stearic acid.
Further, described tenderizer is that viscosity is greater than 30mm
2the high viscosity paraffinic hydrocarbon process oil of/s.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: coordinated the compression set of the terpolymer EP rubber of cyanacrylate sulfuration little by dicumyl peroxide, coordinate spray carbon black then can reduce the compression set of rubber further again, full-bodied paraffinic hydrocarbon process oil is used to be conducive to crosslinked reflection, and effectively can ensure that cross-linked rubber has good aging resistance, and process safety performance is good.
