Product prepared from additive type biodegradable composition

Abstract

The invention provides a product prepared from an additive type biodegradable composition. The product is prepared by the following steps: grinding sodium sulfate or a starch material until powder with a size over 1000 meshes is obtained, then adding synthesized biodegradable resin as the main raw material and other additives, mixing, stirring the mixture in a high-low temperature boiler in a high speed until the mixture becomes paste, then kneading the paste in a kneading machine, cooling to obtain blocks, transferring the blocks to a granulating machine to carry out mixing and granulating, cooling the granules by water, cutting and forming to obtain biodegradable composition particles, and finally making the biodegradable composition particles into biodegradable products such as bags, tableware, and the like. The product has the advantages of high heat resistant temperature, high transparency, low cost, and easy degradation, can be degraded in nature, and will not pollute the environment.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to products made of additive biodegradable compositions. Background technique [0002] In order to solve the shortcomings of non-decomposable plastic products, those skilled in the art use biochemical technology to process plants through refining, fermentation, synthesis and other steps to make decomposable products. The physical and chemical properties of this product are close to those of ordinary plastics, so it can be used Use to replace plastic products. Biodegradable materials must be very stable during manufacture and use, but must be decomposed into biomass, carbon dioxide and water, which are ubiquitous in nature, within a reasonable time after use and disposal. The formation of biomass energy is beneficial to the environment because the process fixes carbon in nature better than incineration, and it can be absorbed by plants. Therefore, waste biodegradable materials can b...

Problems solved by technology

Since starch itself contains oil, secondary processing is required, resulting in cumbersome process and high cost of obtaining starch, and the finished product produced after blending starch and synthetic resin is dark foggy, not high in transparency, resulting in visual unsightly

This type of material is not easy to decompose. Although there have been a large number of patent literature reports on starch parameters, denaturation, processing technology, formula, resin modification, etc., the blending process has not fundamentally changed the structure of this synthetic resin. Therefore, when the starch is decomposed quickly, the decomposition of the residual synthetic polymer phase is still very slow, so it is difficult for this kind of biodegradable plastic to overcome the shortcomings of zero pollution, non-recyclable, etc., and it is also impossible to obtain the certification of biodegradation testing standards license

[0004] Therefore, how to solve the problems of cumbersome, high cost and difficult to decompose the current production process of biodegradable materials, and the shortcomings of environmental pollution and environmental protection operations that cannot meet the detection standards have become the direction that researchers in this field want to study and improve.
