The invention relates to an environment-friendly type extruded plastic board and a preparation method thereof. The board comprises the following
raw material components in parts by weight according tothe proportion: 60-80 parts of
polystyrene resin, 20-30 parts of
epoxy resin, 10-15 parts of white
carbon black, 10-15 parts of hollow glass beads, 5-8 parts of
calcium carbonate, 6-7 parts of
silicon carbide, 4-8 parts of tetrafluorodichloroethane, 3-5 parts of
coconut diethanolamide, 6-10 parts of deionized water, and 10-20 parts of
argon gas. The product has the advantages of easily availablematerials, low cost,
environmental protection and green, uniform dispersibility of internal structure, large foam volume, large density, good insulation effects, excellent sound insulation effects, good
fire protection ability, portable quality, transport and installation convenience, saved manpower, reduced cost, good stability, good anti-compression capability, good insulation effects, and certain antivibration effects.
