Abstract
The composite thermal insulation material made of forest remainders and expanded polystyrene foams and preparation method thereof relates to a thermal insulation material and a preparation method thereof. The present invention is to solve the problems of high cost, low strength, and serious pollution of the prior expanded polystyrene foamed thermal insulation material. The thermal insulation material of the present invention consists of materials with the following weight portions: 80 to 120 portions of forest remainders, 10 to 30 portions expanded polystyrene foam particles, 10 to 35 portions of adhesives and 0.3 to 2 portions of coupling agents. The preparation method is that wood particles and expanded polystyrene foam particles are put in a mixer. Coupling agents and adhesives are sprayed respectively in the mixer while the wood particles and expanded polystyrene foam particles are mixed. A uniformly mixed material is assembled immediately and pressed. The present material has the advantages of thermal insulation, sound insulation, shock absorption, a strong binding strength, a widened application scope and a convenient construction and improves the utilization ratio of forest remainders. In addition, the present material can be recovered and recycled. The preparation method has the advantages of a simple method, a high productivity and does not pollute the environment.
