Environmental-friendly material used for imitation porcelain tableware and preparing method thereof

Abstract

The invention discloses an environmental-friendly material used for imitation porcelain tableware. The material comprises cereal protein plastic, a heat stabilizer, a reinforcing agent and a crosslinking agent. A preparing method of the material includes: heating and mixing the cereal protein plastic, the heat stabilizer and the reinforcing agent to obtain a premix, subjecting the premix to plasticizing, mixing, granulation and cooling to obtain granules; uniformly mixing the granules and the crosslinking agent, smashing and processing into the bio-based material used for the imitation porcelain tableware. The material for the imitation porcelain tableware is advantageous in that: 1) materials adopted are safe biomass materials, the preparation technology is simple and the material can be continuously produced; 2) the prepared material can be directly used in forming and processing lines of the imitation porcelain tableware at present, without the need of adding new producing equipment; and 3) the produced imitation porcelain tableware overcomes the safe and sanitary problems and the problem of incapability of being used in a microwave oven of melamine-formaldehyde resin imitation porcelain tableware at present.

Description

technical field [0001] The invention relates to a tableware material and a preparation method thereof, in particular to an environment-friendly material for imitation porcelain tableware and a preparation method thereof. Background technique [0002] Imitation porcelain tableware is a kind of tableware made of resin, which is similar to porcelain in appearance. It is stronger than porcelain, not easy to break, and has bright color and strong finish. It is very popular among children. At present, the material for manufacturing melamine tableware in my country is mainly melamine-formaldehyde resin, also known as melamine resin. The melamine tableware produced by it has the following deficiencies: (1) Tableware residues of melamine and formaldehyde are harmful to human health (2) Tableware cannot be used in microwave ovens; (3) Tableware cannot be biodegraded after use and has an impact on the environment. [0003] Protein plastics are one of the widely used natural polymer ma...

AI Technical Summary

Problems solved by technology

At present, the material for manufacturing melamine tableware in my country is mainly melamine-formaldehyde resin, also known as melamine resin. The melamine tableware produced by it has the following deficiencies: (1) Tableware residues of melamine and formaldehyde are harmful to human health cause harm; (2) tableware cannot be used in microwave ovens; (3) tableware cannot be biodegraded after use and has an impact on the environment

Protein plastics, especially cereal protein plastics, are excellent bioplastic materials that are free of harmful substances and can be degraded. Due to the pyrolysis properties of proteins, direct application to manufacture melamine tableware has low heat resistance and strength, which cannot meet the needs of melamine tableware. During normal use, vegetable protein plastics limit the application in the production of environmentally friendly melamine tableware

At present, there is no report on the technology of using cereal protein plastics to produce environmentally friendly melamine tableware materials
