(3) material II and polyacrylamide are added in material I, 3-5h is stood at -5-0 DEG C is gone to after being sufficiently mixed, most
After be heated to 120-125 DEG C insulation mixing 10-15min.
The preparation method of the modified hydrogenated styrene-butadiene block copolymer is：By 10-15 part hydrogenated styrenes-
During butadiene block copolymer adds 20-30 hexamethylenes, after dissolving completely, 2-3 parts polyvinyl butyral resin and 0.5-1 are added
The double trifluoromethanesulfonimides of part, are sufficiently mixed microwave treatment 2-3min under microwave frequency 2450MHz, power 700W, so
1-2 part C5 Petropols and 0.5-1 part sulfurized lards are added afterwards, continue microwave treatment 3-5min, subsequently by institute after being well mixed
Obtain mixture to cool with the speed of 10-15 DEG C/min under ice salt bath, insulated and stirred 15- after temperature is down to 0-5 DEG C
30min, finally heated to 80-90 DEG C insulation mixing 10-15min.
Hydrogenated styrene-butadiene block copolymer strengthens which compatible with oil resistance agent remaining raw material by above-mentioned modified
Property, improve its shortcoming poor with high molecular polymer blending property, while improving the grease resistance of itself.
The invention has the beneficial effects as follows：The present invention is aided with various auxiliary agents with ultra-fine polytetrafluorethylepowder powder as primary raw material
Prepared hydraulic cylinder sealing rubber Organic fluoride oil resistance agent, the Organic fluoride oil resistance agent directly make an addition to the preparing raw material of caulking gum
In, there is preferable compatibility with remaining preparing raw material of rubber, made caulking gum has excellent resistance to hydraulic oil
Oiliness, can effectively slow down the corrosion rate under hydraulic oil pressure effect internally and after hydraulic oil intensification to caulking gum, it is ensured that
Sealing effectiveness, while extending the service life of caulking gum.Find Jing after actually used, made caulking gum is normally used 1 year
There is not the phenomenon corroded by hydraulic oil in its surface afterwards, and outside does not have hydraulic oil to ooze out, and sealing effectiveness meets hydraulic cylinder
Use requirement.
