[0019] In parts by weight, add 70 parts of butylene terephthalate, 60 parts of filler, 2 parts of coupling agent, 2 parts of curing agent, 2 parts of zinc stearate, 8 parts of talcum powder in the mixer , 2 parts of emulsifier OP-10, 5 parts of thickener, stirring and mixing at a high speed for 30 minutes under the condition of 1200r / min at a rotating speed to obtain a mixed slurry; Biogas slurry, put the mixed slurry and biogas slurry into the fermentation tank, under the condition of temperature of 28°C and rotation speed of 200r / min, after constant temperature and closed fermentation for 5 days, the fermentation slurry was obtained, and then the fermentation slurry was poured into the gypsum mold. At a temperature of 100°C, solidify for 8 hours to obtain a billet, then move the billet to a vacuum freeze-drying oven and dry for 40 minutes to obtain a dry billet, then mix and soak the dry billet and a mass concentration of 2g / L dopamine solution at a mass ratio of 1:60 After ...
