Plant fiber composition, composite material, and preparation method and applications thereof

Abstract

The invention provides a plant fiber composite material. The preparation method of the plant fiber composite material comprises the following steps: mixing 60-80 wt% of plant fiber raw material, 10-30 wt% of starch assistant and 10-20 wt% of biopolymer additive to form a mixture; and banburying the mixture under increased pressure at 90-120 DEG C, and extruding to make mixed granules, thereby obtaining the plant fiber composite material. The proportion of the mixture can be adjusted according to the requirements of the finished products. The composite material has the characteristics of low dampness capacity, high water resistance, high bearing capacity and the like. The composite material can be used instead of the traditional plastic material as packaging and plant rearing materials of food containers, electronic products, agricultural products and the like, or instead of wooden materials in the fields of architecture, decorations, furniture and the like. The composite material can be recycled and can not result in environmental pollution, thereby achieving the goal of environmental protection.

Description

technical field [0001] The present invention relates to a renewable resource material that is non-toxic, harmless, high in resource utilization, and less in pollutant output, and in particular to a plant fiber composite material that can be used in various products such as injection molding to replace plastic materials. Use; It can be used for extruded imitation wood products to replace the use of wood materials. Background technique [0002] With the progress of society and the rapid development of global industry and commerce, the use of daily products such as plastic materials that cause environmental pollution has improved the convenience of human life, but it has also resulted in the rapid deterioration of environmental quality, causing harm to human beings. The threat to health and life is becoming more and more serious.

Problems solved by technology

[0002] Along with the progress of society and the rapid development of global industry and commerce, the use of daily products such as plastic materials that cause environmental pollution has improved the convenience of human life, but it has also resulted in the rapid deterioration of environmental quality, causing harm to human beings. Threats to health and life of

In addition, with the dwindling of environmental resources and the rise of international crude oil prices, the cost of plastic materials has also increased.

[0003] On the other hand, due to the huge amount of paper products used in the cultural industry and commercial packaging, the number of trees cut down for papermaking is huge, far exceeding the growth rate of plants. Therefore, large areas of forest trees on the surface of the earth are gradually disappearing, which seriously affects the transformation of photosynthesis into carbon dioxide. quantity, resulting in an increasingly serious greenhouse effect
