Abstract
The invention provides a preparation method for antistatic silicone rubber. The preparation method comprises the following steps: step 1, adding 75 parts by weight of mixed silicone rubber with hardness of 30 DEG and 0.2 part by weight of a coupling agent into a kneader; second 2, adding 25 parts by weight of a conductive material into the kneader, wherein the conductive material is prepared by blending methyl vinyl silicone raw rubber and acetylene black according to a weight ratio of 60: 40; step 3, fully kneading the above-mentioned mixtures by using the kneader; and step 4, carrying out material discharging. According to the invention, since the conductive material prepared by blending methyl vinyl silicone raw rubber and acetylene black according to a weight ratio of 60: 40 is employed and proportions of all the components are reasonably set, the prepared antistatic silicone rubber has good antistatic and processing performance.
Description
Technical field
The present invention relates to chemical field, particularly relate to a kind of preparation method of antistatic silicone rubber.
Background technology
Current antistatic silicone rubber often, by taking rubber unvulcanizate as base-material, adds mixing the forming of static inhibitor of liquid.But owing to having added liquid static inhibitor, easily there is following problem: 1, product antistatic property is poor in antistatic silicone rubber prepared by this preparation method; 2, physicals and processing characteristics are bad; 3, do not have the effect of the eliminostatic that Silica Surface is produced; 4,, through high temperature with for a long time, antistatic effect can variation, even disappearance.
Summary of the invention
Based on this, the invention provides and a kind ofly have compared with the preparation method of the antistatic silicone rubber of high-antistatic coefficient and good physicals and processing characteristics.
A preparation method for antistatic silicone rubber, this preparation method comprises the following steps: the first step by weight, adds melting silicone rubber that 75 parts of hardness are 30 degree and the coupling agent of 0.2 part in kneader; Second step adds 25 parts of electro-conductive materials in kneader, the ratio mixture that this electro-conductive material is 60:40 by methyl ethylene silicon raw rubber and Shawinigan black according to ratio of weight and number; The 3rd step, kneader is fully mediated these mixtures; The 4th step, discharging.
Further, in described the 3rd step, kneader is described mixture to be mediated 1.5 hours under lower than the condition of 80 degrees Celsius in temperature.
Further, the coupling agent in the described the first step is vinyltriethoxysilane.
The preparation method of antistatic silicone rubber of the present invention, by adopting the electro-conductive material of ratio mixture and the ratio of each composition that methyl ethylene silicon raw rubber and Shawinigan black are 60:40 according to ratio of weight and number, makes the antistatic silicone rubber being prepared from possess good antistatic property and processing characteristics.
Embodiment
The invention provides a kind of preparation method of antistatic silicone rubber, this preparation method comprises the following steps: the first step by weight, adds melting silicone rubber that 75 parts of hardness are 30 degree and the coupling agent of 0.2 part in kneader; Second step adds 25 parts of electro-conductive materials in kneader, the ratio mixture that this electro-conductive material is 60:40 by methyl ethylene silicon raw rubber and Shawinigan black according to ratio of weight and number; The 3rd step, kneader is fully mediated these mixtures; The 4th step, discharging.
Wherein, in described the 3rd step, kneader is described mixture to be mediated 1.5 hours under lower than the condition of 80 degrees Celsius in temperature.
Wherein, the coupling agent in the described the first step is vinyltriethoxysilane.
In invention, described melting silicone rubber refers to by raw-silastic continuously and is added on twin-screw extruder or in airtight kneader and adds gradually White Carbon black, and silicone oil etc. and other auxiliary agent are refined the synthetic rubber forming repeatedly.
The preparation method of antistatic silicone rubber of the present invention is by adopting the electro-conductive material of ratio mixture and the rational proportion of each composition that methyl ethylene silicon raw rubber and Shawinigan black are 60:40 according to ratio of weight and number, the antistatic silicone rubber hardness that makes to prepare reaches 40 degree, antistatic coefficient reaches 107 rank, and antistatic property can not disappear with high temperature vulcanized, and energy long-term existence, thereby possess good antistatic property and processing characteristics.
It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, adopt the above embodiment of the present invention to adopt and same or analogous method described in the embodiment of the present invention, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
