Problems solved by technology

The application of plastic products not only brings great convenience to people, but also brings serious negative effects. Except that most waste plastic products can be degraded under special conditions, their light and biodegradation speeds in the natural environment are very slow , although it can be disposed of by landfill, incineration and other methods, these methods have great defects. "White waste" not only affects the ecological balance, but also threatens human health
[0003] In order to solve this problem, degradable plastic materials have become the focus of researchers. Although the research on degradable materials has achieved certain results, the existing degradable materials generally have insufficient degradation, long degradation time, high brittleness, High cost of raw materials, poor waterproof performance, complex production process, low production capacity and other defects limit the scope of application

Abstract

The invention discloses a degradable material as well as a preparation method and application thereof. The degradable material specifically comprises the following components in parts by weight: 40-60 parts of bran powder, 15-25 parts of modified plant fiber powder, 1-5 parts of a natural plasticizer, 0.5-1 part of a curing agent, 5-10 parts of modified starch, 1-5 parts of an auxiliary agent and 1-10 parts of melamino-formaldehyde resin. Through modification and compounding of bran and shell agricultural by-crops and with the assistance of the melamine formaldehyde resin, the physical performance and waterproof performance of the product are improved, and the product is good in toughness, small in brittleness, cheap in material taking and simple and rapid in production process, can be widely applied to the fields of disposable tableware, kitchen ware, flowerpots and the like, and has a wide application prospect. The product is safe and environment-friendly and has good disintegration and degradation properties.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a degradable material and its preparation method and application. Background technique [0002] Plastic products have the characteristics of high strength, high toughness, light weight, and low price, and are widely used in people's production and life. The application of plastic products not only brings great convenience to people, but also brings serious negative effects. In addition to the fact that most waste plastic products can be degraded under special conditions, their light and biodegradation speeds in the natural environment are very slow , although it can be disposed of by methods such as burial and incineration, but these methods have great defects. "White garbage" not only affects the ecological balance, but also threatens human health. [0003] In order to solve this problem, degradable plastic materials have become the focus of researche...
