Abstract

The invention discloses a fast-degradation plant fiber material. The fast-degradation plant fiber material comprises, by mass, 60-80% of plant fibers, 30-60% of natural starch, 6-10% of polypropylene,8-12% of polyvinyl chloride, 10-14% of polyvinyl alcohol, 5-9% of a reactive assistant, 10-20% of a plasticizer, 11-17% of talcum powder, 11-17% of paper pulp, 6-12% of an adhesive, 8-10% of a fillerand 2-4% of a cross-linking agent. The plant fiber material can be fast degraded, and still can ensure the compression strength, the tensile strength, the bending strength, the hardness and the impact degree.

Description

technical field [0001] The invention relates to the technical field of plant fiber materials and techniques, in particular to a fast-degrading plant fiber material and a preparation method. Background technique [0002] Plant fiber materials have the advantages of convenient material extraction, low cost, environmental protection, and low production energy consumption. At present, they have been widely used in sound insulation materials, thermal insulation materials and other fields, and have great application prospects in the field of decorative materials due to their degradability. However, the current plant fiber materials still have low compressive strength, tensile strength, bending strength, hardness and impact when a certain speed is guaranteed, so there is a problem that they are not widely used. [0003] Therefore, it is very necessary to invent a fast degrading plant fiber material and a preparation method that can degrade quickly and still ensure compressive stren...
