Biodegradable plastic adopting grass powder as raw material

Abstract

The present invention discloses a biodegradable plastic adopting grass powder as a raw material. The biodegradable plastic comprises 30-60% of grass powder, 20-45% of PE, 3-10% of a modifying agent, 3-10% of a binder, and 3-5% of a bleaching agent. According to the present invention, the grass powder is used as the base raw material and is co-mixed with the PE, the modifying agent, the binder and the bleaching agent according to the specific component ratio to prepare the biodegradable plastic, such that the product has the biodegradable property, the purposes of energy saving, emission reducing and environmental protection are achieved, the raw material cost is low, and the promotion and application is easily achieved. The biodegradable plastic of the present invention is applied in the field of biodegradable materials.

Description

technical field [0001] The invention relates to the field of biodegradable materials, in particular to a biodegradable plastic made of grass powder. Background technique [0002] Plastic products are widely used in many fields such as human life and industrial production. Traditional plastic products use PE material as the basic raw material, which has the problems of high energy consumption and serious pollution. Taking plastic bag products as an example, relevant data shows that plastic bags from From production to processing, the whole process will cause a lot of resource consumption and pollution of the earth's environment. The natural decomposition of each plastic bag takes more than 200 years, which will pollute the surrounding land and water quality. The plastic packaging bags consumed in the country every year consume more than 10 million barrels of crude oil in production, and consume more electricity when processing. It is astonishingly large; and with the improve...

The natural decomposition of each plastic bag takes more than 200 years, which will pollute the surrounding land and water quality. The plastic packaging bags consumed in the country every year consume more than 10 million barrels of crude oil in production, and consume more electricity when processing. It is astonishingly large; and with the improvement of people's living standards, the requirements for the environment are getting higher and higher. Traditional plastic raw materials are gradually eliminated due to their high energy consumption and serious environmental pollution, which are difficult to meet the use requirements. Biodegradable Plastic raw materials become a substitute for traditional plastics. Due to their biodegradable characteristics, the severity of environmental pollution is greatly improved, and the use of PE materials is reduced to a certain extent, thus reducing the consumption of traditional energy. However, due to Most of the biodegradable plastics currently used in the market are made of starch as a basic raw material mixed with PE materials. As we all know, starch is used as an edible plant resource. Applying it as a basic raw material to the preparation of plastic raw materials will inevitably affect the use of starch as an edible plant. The supply of resources leads to a reduction or even shortage of the supply of edible starch, which further affects the fluctuation of starch prices. At the same time, it also leads to unstable prices of biodegradable plastics and even higher costs, which limits the wider application of biodegradable materials.
