Abstract
The invention relates to preparation of silicon rubber materials, in particular to an oil proof methylvinylsilicone rubber and a method for preparing the same. The oil proof methylvinylsilicone rubbercomprises the following raw materials in part by weight: 10 to 25 parts of crude rubber of which the molar content of vinyl groups is 1 percent, 60 to 100 parts of crude rubber of which the molar content of vinyl groups is 0.05 percent, 40 to 60 parts of pyrogenic silica, 5 to 10 parts of dimethyl dimethoxy silane, 10 to 100 parts of magnesium hydroxide, 10 to 100 parts of kieselguh, 10 to 30 parts of microsilica, 1 to 3 parts of vinyl tri-methoxysilane, and 2 to 4 portions of cerium oxide. Actual tests show the oil proof methylvinylsilicone rubber possesses good oil proof performance and canmeet general requirements for the oil proof property.
Description
Technical field
The present invention relates to the manufacturing of silastic material, specifically is a kind of oil resistant methyl vinyl silicone rubber and manufacture method thereof.
Background technology
Silicon rubber possesses a lot of excellent performances such as good high-low temperature resistant, anti-ozone, weathering resistance, insulativity and production inertia, has a wide range of applications in the every field of national economy.Methyl vinyl silicone rubber itself is the ability that does not possess anti-anti-non-polar solvent, this has limited silicon rubber contacts more industrial circle with solvent at automobile etc. use, though the better kinds of anti-non-polar solvent such as trifluoropropyl siloxane, nitrile silicone rubber occurred, but, it can not big area be promoted owing to production cost height, technology barriers height.Possesses crucial Research Significance so improve the oil-proofness of methyl vinyl silicone rubber to a certain extent.
The present invention wants the technical solution problem to be, provides a kind of and can satisfy oil resistant methyl vinyl silicone rubber and the manufacture method thereof that general oil resistant requires.
The weight part that its raw material of oil resistant methyl vinyl silicone rubber of the present invention is formed is:

Diatomite 10-100 part
Silicon powder 10-30 part
Vinyltrimethoxy silane 1-3 part
Cerium oxide 2-4 part.
Manufacture method of the present invention is based on above-mentioned raw material to be formed, and its steps in sequence is:
A. the vinyl molar content is surpassed 1% methyl ethylene rubber, with the vinyl molar content be that 0.05% methyl ethylene rubber stirred in kneader 2-4 minute;
B. white carbon black and dimethyldimethoxysil,ne are added several times, fully stir after each the adding and obtain silicon rubber gross rubber;
C. adding magnesium hydroxide, diatomite, silicon powder fully stirs;
After the d.c step is kneaded and formed, be warmed up to 150 degree, vacuumize minute, logical cooling water temperature to 120 degree adds cerium oxide, fully stirs the back plastic emitting;
E. the plastic emitting postcooling obtains product to room temperature.
Product of the present invention has oil resistance preferably through actual tests, and can satisfy the use with general oil-proofness requirement has occasion.
Embodiment
Embodiments of the invention are made the oil resistant methyl vinyl silicone rubber through following steps,
A. the vinyl molar content is surpassed 1% methyl ethylene rubber, with the vinyl molar content be that 0.05% methyl ethylene rubber stirred in kneader 2-4 minute;
B. white carbon black and dimethyldimethoxysil,ne are divided three addings, and stirred 20 minutes each back that adds, and obtains the silicon rubber gross rubber of mechanical property excellence;
C. adding magnesium hydroxide, diatomite, silicon powder, vinyltrimethoxy silane fully stirs;
After the d.C step is kneaded and formed, be warmed up to 150 degree, vacuumize minute, logical cooling water temperature to 120 degree adds cerium oxide, stirs plastic emitting after 20 minutes;
E. the plastic emitting postcooling obtains product to room temperature.Can add vulcanizing agent again in the use, 170 degrees centigrade of down sulfurations 5 minutes, 200 degrees centigrade of post cures 4 hours.
Above-mentioned raw-material parts by weight are:
20 parts of the rubbers of vinyl molar content 1%
82 parts of the rubbers of vinyl molar content 0.05%
52 parts of gas-phase silicas
8 parts of dimethyldimethoxysil,ne
60 parts of magnesium hydroxides
60 parts in diatomite
15 parts of silicon powders
1.5 parts of vinyltrimethoxy silanes
2.5 parts of cerium oxide
Through the resistance oil silicone rubber of above-mentioned prescription, explained hereafter, performance is as follows:
。
