2) polyurethane, oxidic polyethylene, silicon carbide micro-powder, calcium stearate, linear polyethylene and gas-phase silica are mixed;
3) by step 2) in the heating material frying that mixes, temperature controls at 75-85 DEG C, time controling, at 25-35 minute, then adds lead sulfate tribasic, methyl methacrylate, nanometer boron fibre, elasticity pure-acrylic emulsion, antioxidant, industry glycerol, lac and polyacrylic acid mixing;
4) by step 3) in mixing after material send into freezing equipment, continuous freezing 3-5 hour under the environment of subzero 16-20 DEG C;
5) by step 4) in freezing after material melt through granulator heating, be expressed into mould molding, obtain semi-finished product enclosing cover;
6) to step 5) in semi-finished product add moisturecuring process, obtain finished product enclosing cover; Wherein solidify humidification process and comprise three phases below:
First stage: in control curing room, positive plate solidification temperature is at 60 DEG C, and relative humidity is 100%, and curing time control was at 5 hours;
Second stage: in control curing room, positive plate solidification temperature is at 85 DEG C, and relative humidity is 100%, and curing time control was at 24 hours;
Phase III: in control curing room, positive plate solidification temperature is at 60 DEG C, and relative humidity is 80%, and curing time control was at 5 hours.By adding moisturecuring process, enclosing cover mechanical strength is strengthened, not easy to crack, long service life.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, has good anti-seismic performance, high-low temperature resistant, adapts to various each working environment, not easy to crack, long service life.
