Preparation method of degradable straw fiber foam material

Abstract

The invention discloses a preparation method of a degradable straw fiber foam material and belongs to the technical field of preparation of composite materials. The method comprises the steps as follows: alkalization and modification of straw, preparation of a polyvinyl chloride mixture and formation of the degradable straw fiber foam material. The prepared degradable straw fiber foam material has good physical and mechanical performance, high chemical stability and high strength and is environment-friendly and degradable, the straw serving as the main material comes from reutilized waste, polyvinyl chloride serving as the other main material can be obtained through recycling, the resource can be saved, and the production cost is lower than that of a traditional plastic foam material.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to a preparation method of a straw fiber degradable foaming material. Background technique [0002] In today's society, the demand for traditional plastic foam products is still very large, but traditional plastic foam materials have disadvantages such as easy aging, flammability, low strength, and high density, which lead to large use limitations and are difficult to degrade , the problem of environmental pollution caused by it has gradually become prominent, which greatly limits the traditional plastic foaming materials. [0003] Crop straw is a common resource. Although the recycling and reuse of waste straw has been widely valued by the society in recent years, there are still nearly 30% of straw resources that have not been fully utilized and are still being treated by incineration. This backward treatment method It not only reduces the microorganisms in the land...

[0002] In today's society, the demand for traditional plastic foam products is still very large, but traditional plastic materials have disadvantages such as easy aging, flammability, low strength, and high density, which lead to large use limitations and are difficult to degrade , the problem of environmental pollution caused by it has gradually become prominent, which has greatly restricted the traditional plastic foam materials.

[0003] Crop straw is a common resource. Although the recycling and reuse of waste straw has been widely valued by the society in recent years, there are still nearly 30% of straw resources that have not been fully utilized and are still being treated by incineration. This backward treatment method It not only reduces the microorganisms in the land, but also seriously pollutes the air, hardens the soil, and increases the amount of chemical fertilizers
