A kind of biodegradable material and its preparation method and application

Abstract

The invention belongs to the high-molecular material field, and concretely relates to a biodegradable material, a preparation method and an application used for preparing a container for plant growth. The biodegradable material is prepared from polylactic acid, inorganic powder, starch, PBAT, carboxymethyl cellulose, polycaprolactone and auxiliary agents. The prepared container for plant growth has characteristics of water resistance, oil resistance, leakage resistance, high shock resistance, high rigidness and good flexibility. The biodegradable material can resist a high temperature of more than 50 DEG C and can resist a low temperature of below -15 DEG C. The biodegradability of the biodegradable material is better than present starch and plastic materials and non-woven fabric materials, and the biodegradable material is an ideal substitute of a traditional plastic or paper-based container for plant growth.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a biodegradable material, its preparation method and its use in preparing seedling raising containers. Background technique

[0002] With the rapid development of the plastic industry, plastic seedling containers are also widely used. While it brings great convenience to agriculture, forestry, and flower seedling scale, it also brings serious white pollution to nature and makes the living environment of human beings worse. face a severe test. Traditional plastic seedling containers cannot be biodegraded after use, so they can only be disposed of by incineration. The toxic gases produced by incineration cause serious pollution to the air and the environment. With the increasing awareness of green environmental protection in the world, people began to regulate the use of plastic products, and countries around the world have also introduced relevant "plastic limit" regu...
