Abstract

The invention discloses a renewable resource foaming material and a preparation method thereof, and belongs to the field of packaging materials. The renewable resource foaming material is prepared from 30-90 parts of plant fibers, 0-60 parts of synthetic fibers, 1-10 parts of a dispersing liquid, 1-10 parts of a foaming agent, 5-20 parts of an adhesive, 1-10 parts of a film-forming agent and 0.5-5parts of a nucleating agent. According to the invention, the renewable resource foaming material is prepared by mixing specific straw plant fibers, synthetic fibers, a dispersing liquid, a foaming agent, an adhesive, a film-forming agent and a nucleating agent and then foaming, so that the production efficiency is high, and the rebound resilience, the extensibility, the pressure resistance and the strength of the material can be improved; the selected materials and other auxiliary agents can be recycled, and are good in degradable performance and environment-friendly, the raw materials are easy to obtain, and the cost is low; and the renewable resource foaming material can be recycled, and creates social value and economic value while solving the problem of agricultural wastes.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a renewable resource foaming material and a preparation method thereof. Background technique [0002] With the rapid development of global society and economy, environmental problems are becoming more and more prominent. At present, various non-renewable resources in the world are facing a shortage. In order to solve the contradiction between resources and vision, countries around the world put the main research direction on green materials. Renewable resources are rationally researched and developed to make them functionally close to or surpass materials developed from non-renewable resources. [0003] Plant fiber environmental protection materials are made of rice husk, rice straw, wheat straw, corn stalk, cotton stalk, wood chips, bamboo chips, soybeans and other crop straws, branches, leaves, grass and other municipal greening plant waste rich in wood fiber or other plant s...
