Preparation method of straw buffer material

Abstract

The invention discloses a preparation method of a straw buffer material, and belongs to the technical field of a functional material. Rice straws and a sodium hydroxide solution are stirred and mixed;filtering, washing, drying, crushing and sieving are performed to obtain a pretreated rice straw; the rice straw, bacillus pasteurii bacterial liquid, modified additives, urea and water are mixed andfermented; then, a calcium nitrate solution is dripped; stirring and mixing are performed; filtering, washing, drying and high-temperature treatment are performed to obtain modified rice straws; themodified rice straws, modified bonding agents, foaming agents, plasticizers, calcium carbonate, crosslinking agents, water, modified sepiolite and modified microcapsule are stirred and mixed; injection molding, foaming shaping, drying and demolding are performed to obtain straw buffer materials. The straw buffer material provided by the invention has excellent buffer performance and mechanical property and has wide application prospects.

Description

technical field [0001] The invention discloses a preparation method of a straw buffer material and belongs to the technical field of functional materials. Background technique [0002] In the field of cushioning packaging, EPS (polystyrene foam) and other foam plastic products have become the first choice of cushioning packaging materials due to their superior cushioning performance and low price. However, the use of chlorofluorocarbons as blowing agents in the manufacturing process will damage the ozone in the atmosphere, and these foamed plastic products cannot be degraded naturally, and their waste directly causes pressure on the environment. Therefore, the research on using new, recyclable, or naturally degradable "green packaging materials" to replace foam plastic cushioning materials has very important engineering application value. Among them, polylactic acid has attracted attention as a completely degradable plastic, but a single polylactic acid material has high br...
