The invention discloses a preparation method for a
bamboo charcoal particle-hollow
microsphere-phenolic resin ternary
composite plate, and belongs to the field of
composite material preparation. The preparation method for the ternary
composite plate comprises the steps that moso bamboo is taken to be split, dried, carbonized and rolled into particles for standby application;
ammonium nitrate,
styrene monomers, deionized water, azodiisobutyronitrile and
ammonium lauryl
sulfate are taken to be mixed in a high-pressure reaction kettle, sealing treatment is performed,
nitrogen is introduced, vacuumizing is performed, vinylidene
chloride is added for predispersion treatment, reacting under heating is performed, suction
filtration is performed to obtain filter cakes, the filter cakes are washed by absolute ethyl
alcohol, foamed under heating, dried and then mixed with the standby
bamboo charcoal particles and a phenolic resin
ammonium chloride solution, natural curing is performed on the mixture in a mould, and then the ternary
composite plate is prepared. The preparation method has the advantages of being simple and little in
pollution to the environment in the production process. The obtained product has the good
mechanical property and
heat stability and is little in low temperature
brittleness, capable of resisting the temperature of minus 10 DEG C-380 DEG C, not prone to crack, good in
impact resistance and anti-crack propagation capacity and high in
toughness.
