Starch-containing biomass cane-like material and preparation method thereof

Abstract

The invention discloses a starch-containing biomass cane-like material. The starch-containing biomass cane-like material is prepared from modified starch and thermoplastic plastic; the modified starchis prepared through a following method comprising the steps that raw starch and a modification agent which accounts for 2-20% of the weight of starch are added into a high-speed mixing machine, a mixture is heated to 80-125 DEG C and is stirred for 10-15 min at high speed, and then the modified starch is obtained; a silane coupling agent is adopted as the modification agent, glycerin, hydrochloric acid, sulfuric acid or a hydroxypropyl cellulose solution; the weight ratio of the added modified starch to the added thermoplastic plastic is (20-60):100; one of polylactic acid, low-density polyethylene and linear low-density polyethylene, or a mixture of two or more of polylactic acid, low-density polyethylene and linear low-density polyethylene is adopted as the thermoplastic plastic. The prepared starch-containing biomass cane-like material has good performance, a preparation technology is simple, and the production cost is low.

Description

technical field [0001] The invention relates to a novel rattan weaving material, in particular to a rattan-like material modified with starch for plastics. Background technique [0002] As a traditional weaving material, rattan weaving material has always been favored by consumers. The small ones are like woven baskets, and the big ones are like rattan furniture. They are widely used in offices, outdoor leisure places, and homes. The traditional rattan weaving material uses natural rattan. Although it has the characteristics of good natural texture and renewable characteristics, it is replaced by imitation rattan materials in more and more places due to its susceptibility to mildew, insects, brittle cracks, and resource constraints. [0003] Imitation rattan is mostly made of plastic, mainly including PE rattan and PVC rattan, and their composite rattans; compared with natural rattan, plastic imitation rattan has a longer life, lower cost, rich color and easy processing, but...

AI Technical Summary

Problems solved by technology

[0006] However, in the existing improved granulation of plastics, by directly adding starch to PE, PP or PVC for modification, only the degradability of the final product can be improved, and due to the combination of starch itself with PE, PP or PVC The property of starch is relatively weak, and it cannot greatly improve the mechanical properties of the final product, and the addition of too much starch will reduce the melt index of the material, affect extrusion molding, and increase the degree of wear and tear on the production equipment

Adding modified starch to rattan-woven composite materials can improve the performance of the product, but there is no application and related reports on this aspect so far.
