800rpm, dissolution time 2-10h prepare solution polymerized butadiene styrene rubber glue；To equipped with stirring, thermometer device in be added it is non-from
Subtype emulsifier, anionic emulsifier, defoaming agent, deionized water, controlled at 30-80 DEG C, speed of agitator 100-
800rpm, mixing time 10-60min, prepares emulsifier aqueous solution；Solution polymerized butylbenzene glue is mixed with emulsifier aqueous solution and is added
Enter in high-shear emulsion machine and emulsified, control emulsification system pH is 8-12, and mulser revolving speed is 1000-10000rpm, emulsification
Time is 10-60min, the lotion emulsified is recycled organic solvent in heating decompressor, vacuum distillation temperature
It is 50-90 DEG C, the vacuum distillation time is 30-120min, and solution polymerized butadiene styrene rubber latex is finally carried out centrifugal concentrating, centrifugal basket
Speed is 500-2000rpm, and centrifugation time 5-30min obtains solution polymerized butadiene styrene rubber lotion；
Existing preparation method has the following problems；
(1) emulsion dispersion can be such that the fillers such as GO disperse in rubber matrix more uniformly, usually using the demulsification such as acid
The co-precipitation of latex particle and GO is realized in agent, but acid adding or the flocculation of other chemical reagent and subsequent dewatered drying process are easy to make
Filler generation is reunited again, causes low efficiency, the problem that time-consuming and water consumption is big；
(2) while mechanical blending method, solution blended process and melt-blending process are due to technological problems, the rubber composite wood of preparation
