Straw biomass container and preparation method thereof

Abstract

The invention discloses a preparation method for a straw biomass container. The preparation method comprises the following steps: weighing straws and water, carrying out stirring, and adjusting the content of water to 40 to 60%; placing an obtained mixture in a sealed bag for 8 to 14 h; carrying out steam explosion so as to obtain straw fiber, and carrying out drying until the content of water is5 to 15%; adding an adhesive, and carrying out uniform mixing, wherein the ratio of the straw fiber to the adhesive in terms of absolute dry weight is 10: (1-3), and the adhesive is polyvinyl alcohol;carrying out hot-press molding; and carrying out cooling molding. The preparation method for the biomass container provided by the invention is a complete treatment manner with integrity, has the characteristics of environmental friendliness, low energy consumption and simple and easy operation, and is applicable to popularization; and the straw biomass container prepared by using the preparationmethod provided by the invention has the advantages of good moldability, excellent mechanical properties, strong load capacity, environment protection, degradability, and capability of realizing secondary molding processing after curing.

Description

technical field [0001] The invention belongs to the field of container manufacturing, in particular to a straw biomass container and a preparation method thereof. Background technique [0002] According to statistics from the National Development and Reform Commission and the Ministry of Agriculture, in 2015, the theoretical resources of major crop straws in the country were 1.04 billion tons, and the collectable resources were 900 million tons. As a rich biomass resource, it has not been effectively utilized, but also brought a series of environmental pollution problems. [0003] For a long time, the country has attached great importance to the comprehensive utilization of crop straws. Although the comprehensive utilization of straws has achieved certain results, the utilization of straw resources in my country is still in the initial stage of development. "Fertilization" means returning straw to the field, and has not maximized the advantages of straw resources. [0004] ...

AI Technical Summary

Problems solved by technology

[0005] However, due to the poor plasticity of the straw itself, and the fact that mechanical crushing cannot effectively improve the surface properties of the straw, various straw products directly hot-pressed in the mold have poor formability and weak mechanical strength.

[0006] In the existing production processes of various straw products, either a large amount of chemicals are required for treatment, or the processing steps are complicated and time-consuming, or the cost of raw and auxiliary materials is high, or the biodegradability of the adhesive is insufficient. A series of problems, resulting in poor mechanical properties of biomass containers, high energy consumption, high production costs, can not effectively achieve environmental protection, and is not conducive to large-scale promotion
