Disposable corn starch tableware is a new type of resin added with starch and other inorganic macromolecular natural substances and some inorganic salts as raw materials, which has the free radical oxidation and biodegradation caused by UV activation (namely the microbial decomposition of mold).
Blending of biodegradable copolymers, as the main research direction in the high-tech field, has become a research hotspot. The focus of competition in the field of technology is to increase as many degradation substances as possible. Keep the original physical and mechanical properties and reasonable price of plastics.
Degradation copolymers in disposable corn starch tableware, in any small part, its better spatial structure, for example, when degradation materials are degraded, the whole material is decomposed into a single broken geometry, and the molecular weight of these geometry is greatly reduced, which is easy to be consumed by nature. In the actual operation process, the key solution is:
One is the force between the degradation material and the whole material. Because it is not covalent bond force or ionic bond force in chemical change, and Newton's gravity is far from meeting the requirements of product strength. Therefore, the problem of making it as intermolecular as possible in the micro space is solved. This is the first difficulty in the formation of the refractory copolymers.
The other is to solve the problem of incompatibility between the degradation material and the whole material. Take starch and PE for example. The former is strongly polar and the latter is nonpolar. The two are not compatible. The solution is to add cross-linking agent, coupling agent, surfactant and other substances between them, which are two difficulties in the preparation of degradable copolymers.
