Abstract
The invention provides a foaming formula for an automobile sealing strip. The foaming formula is prepared from 30-35 parts of crude rubber, 21-31 parts of reinforcing filler, 3-6 parts of a softener, 2-4.5 parts of an active agent, 0.9-1.1 parts of a foaming agent and 1-1.3 parts of a vulcanization accelerator in weight. The foaming formula for the automobile sealing strip is added with the organic foaming agent through a reasonable proportion, so as to ensure good storage stability, no toxicity, no odor and no pollution of automobile sealing strip products, and complete a gas forming effect in a short time at high temperature. The gas forming amount can be regulated, decomposition is adequate, the generated heat is small, the grain size is uniform, gas is easily dispersed, and a uniform and fine microporous sponge structure is formed.
Description
Technical field
The present invention relates to a kind of weather strip for automobile foaming product, especially a kind of weather strip for automobile foaming formulation.
Background technology
Current weather strip for automobile is produced the foaming formulation adopting, foam hole is not enough, foam hole inhomogeneous (excessive or too small), foam hole is excessive, and hardness, the density of product are sub-standard, and closed pore can become connection hole, micropore becomes aperture, some part is subsided or some part can not sent out, and affects foaming quality, after weather strip for automobile is installed, cause installation position poorly sealed, cause client seriously to complain.
Summary of the invention
The object of this invention is to provide a kind of weather strip for automobile foaming formulation, can guarantee the foaming quality of weather strip for automobile product, guarantee installation position sealing effectiveness, eliminate Gu client and seriously complain.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: weather strip for automobile foaming formulation, is characterized in that: by the rubber of 30~35 weight parts, the tenderizer of the reinforcing filler of 21~31 weight parts, 3~6 weight parts, the whipping agent of the promoting agent of 2~4.5 weight parts, 0.9~1.1 weight part, the vulcanization accelerator of 1~1.3 weight part form.
Improvement to technique scheme: described rubber is the Jilin Chemical 4045 of 30~35 weight parts; Reinforcing filler is the carbon black N550 by 15~20 weight parts, the calcium carbonate of 5~8 weight parts, and the calcium oxide of 1~3 weight part forms; Tenderizer is the aromatic hydrocarbon oil by 2~3 weight parts, and the paraffin oil of 1~3 weight part forms; Promoting agent is the nano zine oxide by 1~3 weight part, and the stearic acid of 1~1.5 weight part forms; Whipping agent is the ADCA by 0.5~0.6 weight part, and the OBSH of 0.4~0.5 weight part forms; Vulcanization accelerator is the sulphur by 0.3~0.6 weight part, the accelerant NOBS of 0.1~0.3 weight part, the promotor ZDMC of 0.1~0.3 weight part, the promotor TT of 0.2~0.4 weight part, the promotor EZ of 0.1~0.3 weight part, the vulkacit D PG of 0.2~0.4 weight part forms.
Beneficial effect:
Weather strip for automobile foaming formulation of the present invention, by rational proportioning, add organic blowing agent ADCA (Cellmic C 121)/OBSH(couple, to '-be oxidized two benzsulfamides), guarantee that the stability in storage of weather strip for automobile product is good, nontoxic, odorless, do not produce pollution, at high temperature, can the short period of time complete the effect of getting angry, and gas forming amount is adjustable, decomposes fully, the heat producing is little, epigranular, easily disperses, and forms evenly fine and closely woven microporous sponge structure.
Embodiment
By the following specific examples further illustrate the invention.
