Abstract

The invention discloses sugarcane peel fiber based blended PBS (polybutylene succinate) degradable plastic and a preparation method of the degradable plastic. The degradable plastic is prepared from the following raw materials in parts by weight: 100 parts of PBS, 10-20 parts of silane coupling agent modified sugarcane peel fiber, 1-10 parts of polypropylene grafted maleic anhydride, 0.1-2 parts of vegetable oil and 0.1-1 part of antioxidant. The degradable plastic adopts melt blending of the silane coupling agent modified sugarcane peel fiber and PBS resin, and uses a waste biomass resource, namely sugarcane peel, so that the problems of environmental pollution and the like caused by discard of the sugarcane peel can be avoided, the sugarcane peel can be recycled, and the production cost is greatly lowered; and a degradation rate of the degradable plastic in natural soil is higher than that of pure PBS, so that the degradation time is saved.

Description

technical field [0001] The invention relates to the technical field of PBS plastics, in particular to a sugarcane husk fiber-based blended PBS degradable plastic and a preparation method thereof. Background technique [0002] With the increasingly serious problems of environmental pollution and energy shortage, the development and application of environmentally friendly materials have become the focus of research. Environmentally friendly materials use renewable resources as raw materials, the products are biodegradable, the sources of raw materials are abundant, and the advantages of product degradation and pollution-free promote their vigorous development and application. In the process of product development, degradable polymers have received extensive attention due to the use of non-petroleum raw materials. PBS (polybutylene succinate) is a degradable plastic with good mechanical properties, degradation properties and processing properties, but its processing temperatur...
