Problems solved by technology

But in the end, it is because the petroleum-based resin only becomes the most granular, and it cannot be completely biodegraded
Invention patent of a biodegradable nylon 6 / starch composite material and its preparation method (application number 201310112187.X) proposes biodegradable nylon 6 starch composite material, but does not reveal the starch modification method, so it has not been realized in the true sense starch plasticization
Since the molecular formula of starch is (C 6 h 10 o 5 )n, is a polyhydroxy natural polymer compound, which can be regarded as a polysaccharide formed by condensation of D-glucose units. The molecules are associated with each other by hydrogen bonds to form starch granules. The solubility is very poor, and it is hydrophilic but does not melt. Water, due to the strong hydrogen bond between molecules, it is difficult to form and process
So far, it has not really achieved the complete plasticization of starch, and it is also a problem to improve water resistance, so it affects the use of starch base

Abstract

The invention belongs to the field of biodegradation, in particular to starch-base tableware and a manufacturing method thereof. The starch-base tableware comprises modified plant starch, a plasticizer, a modifier, biology-based resin, inorganic powder and deionized water, wherein the modified plant starch is formed by adding a surfactant to one or more of cassava starch, corn starch and sweet potato starch and mixing. By means of the starch-base tableware and the manufacturing method thereof, the problem that a product is hard and fragile due to temperature, humidity or air pressure is solved, pollution of the surface of the product caused due to the fact that environment influences small-molecule material migration is avoided, heat stability of the starch-base tableware is improved, the retrogradation phenomenon is overcome, and the product is more flexible. The invention further provides the manufacturing method of the starch-base tableware, the process is simple, investment is little, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of biodegradation, and in particular relates to a starch-based tableware and a preparation method thereof. Background technique [0002] Bio-based complete degradation has become a new type of packaging material that can replace petroleum resources. , and the research and development of polyvinyl alcohol and starch base have been vigorously developed. my country is a country with a large population and consumes a large amount of petroleum plastics, which has brought serious consequences to environmental pollution. However, due to the high price of bio-based resins, it brings unnecessary losses and burdens to consumption, and starch-based resins have been researched and developed in my country for many years, especially the packaging products made of starch and petroleum-based resins are widely used. However, although the cost of this material is very low, it can play a certain role. But in the end, it is because pe...
