Abstract
The preparation method of a kind of antistatic silicone rubber, this preparation method comprises the following steps: the first step, by weight, adds melting silicone rubber and the coupling agent of 0.2 part that 75 parts of hardness are 30 degree in kneader；Second step, adds 25 parts of conductive materials in kneader, this conductive material by methyl ethylene silicon raw rubber and acetylene carbon black according to the ratio mixture that ratio of weight and number is 60:40；3rd step, these mixture are fully mediated by kneader；4th step, discharging.The preparation method of the antistatic silicone rubber of the present invention is by using methyl ethylene silicon raw rubber and acetylene carbon black according to the conductive material of the ratio mixture that ratio of weight and number is 60:40 and the ratio of each composition so that the antistatic silicone rubber being prepared from possesses good antistatic property and processing characteristics.
Description
Technical field
The present invention relates to chemical field, particularly relate to the preparation method of a kind of antistatic silicone rubber.
Background technology
Current antistatic silicone rubber is often through with elastomeric compound as base material, and the antistatic additive adding liquid is mixing
Form.But, antistatic silicone rubber prepared by this preparation method, owing to adding liquid antistatic additive, holds
Problems with easily occurs: 1, product antistatic property is poor；2, physical property and processing characteristics are bad；3, rise
Effect less than the eliminostatic that Silica Surface is produced；4, through high temperature and long-time after, antistatic effect
Can be deteriorated, even disappear.
Summary of the invention
Based on this, the invention provides and a kind of there is relatively high-antistatic coefficient and good physical property and add
The preparation method of the antistatic silicone rubber of work performance.
The preparation method of a kind of antistatic silicone rubber, this preparation method comprises the following steps: the first step, by weight
Amount part meter, adds melting silicone rubber and the coupling agent of 0.2 part that 75 parts of hardness are 30 degree in kneader；
Second step, adds 25 parts of conductive materials in kneader, and this conductive material is by methyl ethylene silicon raw rubber and second
Alkynes white carbon black is according to the ratio mixture that ratio of weight and number is 60:40；3rd step, these mixture are filled by kneader
Divide and mediate；4th step, discharging.
Further, in described 3rd step, kneader is to described under conditions of temperature is less than 80 degrees Celsius
Mixture is mediated 1.5 hours.
Further, the coupling agent in the described first step is VTES.
The preparation method of the antistatic silicone rubber of the present invention is by using methyl ethylene silicon raw rubber and acetylene carbon black
Conductive material and the ratio of each composition according to the ratio mixture that ratio of weight and number is 60:40 so that system
Standby antistatic silicone rubber possesses good antistatic property and processing characteristics.
Detailed description of the invention
The present invention provides the preparation method of a kind of antistatic silicone rubber, and this preparation method comprises the following steps: the
One step, by weight, adds melting silicone rubber and 0.2 part that 75 parts of hardness are 30 degree in kneader
Coupling agent；Second step, adds 25 parts of conductive materials in kneader, and this conductive material is by methyl ethylene
Silicon raw rubber and acetylene carbon black are according to the ratio mixture that ratio of weight and number is 60:40；3rd step, kneader is to this
A little mixture are fully mediated；4th step, discharging.
Wherein, in described 3rd step, kneader is to described mixing under conditions of temperature is less than 80 degrees Celsius
Thing is mediated 1.5 hours.
Wherein, the coupling agent in the described first step is VTES.
In invention, described melting silicone rubber refers to be added on twin-screw extruder or airtight by raw-silastic continuously
Kneader is gradually added into White Carbon black, the synthetic rubber that silicone oil etc. and other auxiliary agent are refined repeatedly.
The preparation method of the antistatic silicone rubber of the present invention is by using methyl ethylene silicon raw rubber and acetylene carbon black
According to conductive material and the rational proportion of each composition of the ratio mixture that ratio of weight and number is 60:40, make
The antistatic silicone rubber hardness that must prepare reach 40 degree, antistatic coefficient reach 107 rank, and resist
Antistatic property will not with high temperature vulcanized and disappear, and can long-term existence, thus 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 present inventive concept
Under premise, the above embodiment of the present invention is used to use and same or analogous method described in the embodiment of the present invention,
These broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be wanted with appended right
Ask and be as the criterion.
