Abstract
The present invention provides a kind of hydrophilic silicon rubber.The adopted technical solution is that a kind of hydrophilic silicon rubber, including common natural rubber compositions, it is characterized by: 50~100 parts of dimethyl silicone polymer, 4~10 parts of reinforcing filler, 5~8 parts of Trichloromethyl silane, 1~3 part of chlorinated paraffin, 4~6 parts of inorganic potassium salt, 0.1~1 part of catalyst, 1~10 part of crosslinking agent, 10~50 parts of hydrophilic polyether modified silicon oil, 1~5 part of pigment.Compared with prior art, the advantageous effect of present invention is that: the present invention by be added Trichloromethyl silane, chlorinated paraffin, inorganic potassium salt so that the rubber have good hydrophilic effect.
Description
Technical field
The present invention relates to a kind of rubber compositions, more particularly, to a kind of hydrophilic silicon rubber.
Background technique
Organosilicon coating is the coating with organosilicon polymer or silicone modified polymers for main film forming matter, it has
Excellent electrical isolation, Inverter fed motor, weather-proof, humidity and hydrophobic, stain resistant and the performances such as resistant to chemical etching, therefore organosilicon exists
Antifouling work, waterproof are widely applied in antifouling and anticorrosive paint.After room temperature vulcanized silicone rubber is coated in insulator surface,
Film-forming at normal temperature, and with insulator good bond.Because of room temperature vulcanized silicone rubber apparent height hydrophobicity and migration of hydrophobicity
Property, become the preferred coating of electric system power transmission and transforming equipment antifouling work.But it have with organic composite insulator it is similar
Defect such as easily contamination dunghill, be difficult to clean, with filthy long-term accumulation, under the anti-fouling flashover performance of coating is also corresponding
Drop, while room temperature vulcanized silicone rubber also has the shortcomings that poor biocompatibility, body are easy to produce rejection.
Summary of the invention
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of hydrophilic silicon rubber.
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of hydrophilic silicon rubber, feature exist
In the component including following parts by weight:
50~100 parts of dimethyl silicone polymer, 4~10 parts of reinforcing filler, 5-8 parts of Trichloromethyl silane, chlorinated paraffin 1-3
Part, 4-6 parts of inorganic potassium salt, 0.1~1 part of catalyst, 1~10 part of crosslinking agent, 10~50 parts of hydrophilic polyether modified silicon oil, pigment
1~5 part；The catalyst is in organo-tin compound, organotin chelate, organic titanic compound or Organo-Titanate Chelates
One kind.
Further, it is prepared by following step: by the dimethyl silicone polymer of the parts by weight, reinforcing filler, pigment
It is added in kneader and is kneaded uniformly with hydrophilic polyether modified silicon oil, then heat to 130 DEG C, be then kneaded 2~4h, then
1~2h is vacuumized, the crosslinking agent of the parts by weight is added, nitrogen is then passed to and is kneaded 0.5h, add the parts by weight
Catalyst leads to nitrogen and is kneaded 0.5h, then sealed after being vacuumized packaging to get hydrophilic room temperature vulcanized silicone rubber is arrived.
Specific embodiment
To further illustrate the technical scheme of the present invention With reference to embodiment.
A kind of hydrophilic silicon rubber, which is characterized in that the component including following parts by weight:
50~100 parts of dimethyl silicone polymer, 4~10 parts of reinforcing filler, 5-8 parts of Trichloromethyl silane, chlorinated paraffin 1-3
Part, 4-6 parts of inorganic potassium salt, 0.1~1 part of catalyst, 1~10 part of crosslinking agent, 10~50 parts of hydrophilic polyether modified silicon oil, pigment
1~5 part；The catalyst is in organo-tin compound, organotin chelate, organic titanic compound or Organo-Titanate Chelates
One kind.
Further, it is prepared by following step: by the dimethyl silicone polymer of the parts by weight, reinforcing filler, pigment
It is added in kneader and is kneaded uniformly with hydrophilic polyether modified silicon oil, then heat to 130 DEG C, be then kneaded 2~4h, then
1~2h is vacuumized, the crosslinking agent of the parts by weight is added, nitrogen is then passed to and is kneaded 0.5h, add the parts by weight
Catalyst leads to nitrogen and is kneaded 0.5h, then sealed after being vacuumized packaging to get hydrophilic room temperature vulcanized silicone rubber is arrived.
The present embodiment is only presently preferred embodiments of the present invention, is not the limit of other forms made for the present invention
Fixed, any person skilled in the art, as enlightening, is changed or is modified as and is equivalent possibly also with above-mentioned technology contents
The equivalent embodiment of variation.But all technical spirits without departing from the claims in the present invention, the letter to made by above embodiments
Single modification, equivalent variations and remodeling, still fall within the range of the claims in the present invention protection.
