Title:
CHLORINATED POLY(PROPYLENE CARBONATE)/BIOMASS COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/019443
Kind Code:
A1
Abstract:
The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, comprising: 3-57 wt% chlorinated poly(propylene carbonate), 40-94 wt% biological material, 2-20 wt% rosin or derivatives thereof, 0-1 wt% antioxidant, and 0-5 wt% filler, and the sum of amounts of all components is 100 wt%. The chlorinated poly(propylene carbonate) is an adhesive, and plays an important role in humidity resistance of the composite material. The rosin or derivatives thereof are a tackifier and a lubricant, and can improve the humidity resistance and mechanical property of the composite material. By means of the synergistic action of the components, the composite material obtained in the present invention has better mechanical property and humidity resistance. In addition, because the biomass material in the raw material has a large proportion, the cost is low; and there is no formaldehyde, benzene and the like in the raw material, the present invention is environment friendly.
