The invention discloses a bamboo plastic composite for processing a moistureproof, insect-damage-proof and antimicrobial type summer sleeping mat and relates to the technical field of bamboo plastic composites. The bamboo plastic composite is made from the following raw materials, by weight, 20-25 parts of bamboo powder, 10-15 parts of linear low density polyethylene, 10-15 parts of high density polyethylene, 5-10 parts of coconut chaff, 5-10 parts of terpene resin, 3-6 parts of calcined kaolin, 3-6 parts of methylated amino resin, 2-4 parts of powdered acrylonitrile-butadiene rubber, 2-4 parts of sodium carboxymethyl cellulose, 2-4 parts of a toughening agent, 1-2 parts of cationic polyacrylamide, 1-2 parts of nano talcum powder, 1-2 parts of octadecyl trimethyl ammonium chloride, 0.5-1 part of bis(trifluoromethane sulfonimide) and 0.5-1 part of hexamethoxymethylmelamine resin. The bamboo plastic composite is good in forming processing performance, the processed summer sleeping mat has excellent moistureproof performance, insect-damage-proof performance and antimicrobial performance, the using safety is high, the environment protection performance is high, the abrasion resistance, the breathability, the anti-impacting performance and the flame retarding performance are good, and therefore the service life of the summer sleeping mat is prolonged.
