Abstract

The invention discloses a foam board which comprises the following components in parts by weight: 60-100 parts of polylactic acid, 30-50 parts of polyethylene, 6-17 parts of polyethylene glycol ether,2-8 parts of polyester polyol, 5-16 parts of polyester resin, 6-18 parts of starch, 1-5 parts of a foam stabilizer, 2-6 parts of a seaweed extract, 1-4 parts of silicone oil, 3-5 parts of high bauxite, 8-15 parts of ethylene-vinyl acetate, 0.5-3 parts of expanded graphite, 3-7 parts of bamboo fiber, 1-4 parts of magnesium carbonate and 0.2-0.5 part of a stabilizer. The preparation method comprises the steps of mixing, ultrasonic treatment, pre-foaming, extrusion and the like. The foam board is low in degradation rate and long in service life, generated degradation products are almost harmlessto human bodies and the environment, and the foam board has good structural strength and fireproof performance.

Description

technical field [0001] The invention relates to a foam board and a preparation method thereof, belonging to the technical field of foam boards. Background technique [0002] Foam board is made of expandable polystyrene beads containing volatile liquid foaming agent. It is a white object heated and formed in a mold after heating and pre-expansion. It has the structural characteristics of fine closed cells and is mainly used for building walls. , Roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc. [0003] With the development of society and the improvement of people's living standards, the demand for degradable foam boards will increase. At present, the existing foam boards have weak degradability, and the generated degradation products are harmful to the human body and the environment, and at the same time, the fire prevention effect is poor. Contents of the invention [0004...
