High strength starch-based degrading and environment-protecting material and preparation method

Abstract

The invention provides a high-intensity starch-based degradation environmental protection material and a manufacturing method thereof, which relates to a rapid degradation raw material used for manufacturing disposable tableware and disposable wrappage and the manufacturing method thereof. The present disposable foaming plastic tableware has the disadvantages of hard heat insulation, complicated process line, high production cost, undesirable production quality and white pollution. The components of the product include macromolecular natural starch, polyvinyl alcohol, plant sugar, polyvinyl alcohol, a degradation control agent, a multipolymer of polycaprolactone and poly-beta-hydroxybutyrate and hexa-butyl ester hexa-butyl glycan; wherein, the starch is 51-80 weight portions, the polyvinyl alcohol is 12-20 weight portions, the plant sugar is 2-10.5 weight portions, plasticizer is 2.5-8 weight portions, the degradation control agent is 0.2-1 weight portions, the multipolymer of polycaprolactone and poly-beta-hydroxybutyrate is 5-9 weight portions and the hexa-butyl ester hexa-butyl glycan is 0.2-0.5 weight portions. The high-intensity starch-based degradation environmental protection material of the invention is used for manufacturing the disposable tableware and the disposable warppage.

Description

Technical field: [0001] The invention relates to a rapidly degradable raw material for manufacturing disposable tableware and disposable packaging and a manufacturing method thereof. Background technique: [0002] At present, disposable foamed plastic tableware is widely used. Although it brings convenience to people's life, it also causes serious white pollution to the environment. If it is degraded, it can also produce carcinogens such as dioxins after burning. Foam tableware will produce toxins at a temperature of 60°C, which shows how much damage it does to people's living environment and health. Although some starch-based degradable materials that have emerged in recent years have solved the problem of white pollution caused by foamed plastics, due to poor mechanical strength and poor plasticity, these degradable materials require two sets of mixing devices in production, and it is not easy to keep warm during the production process. , complex process lines, high produ...

Problems solved by technology

[0002] At present, disposable foamed plastic tableware is widely used. Although it brings convenience to people's life, it also causes serious white pollution to the environment. After burning, it can produce carcinogens such as dioxins. Foam tableware will produce toxins at a temperature of 60°C, which shows how much damage it does to people's living environment and health.

Although some starch-based degradable materials that have emerged in recent years have solved the problem of white pollution caused by foamed plastics, due to poor mechanical strength and poor plasticity, these degradable materials require two sets of mixing devices in production, and it is not easy to keep warm during the production process. , complex process lines, high production costs, and product quality that does not meet the requirements, so it cannot be widely used
