Abstract

The invention discloses a preparation method of unbreakable melamine resin tableware, which comprises the following steps: melamine resin, bamboo chip fibers, titanate, medical stone nanopowder, epoxysoybean oil, an antioxidant and a lecithin compound are uniformly mixed, a release agent and a hardening agent are added and uniformly mixed, and grinding, screening and hot-pressing formation are performed, so that the unbreakable melamine resin tableware is obtained. The lecithin compound is prepared by adopting the following process: lecithin, silk fibers and absolute ethyl alcohol are uniformly mixed, ammonium persulfate is added and stirred, the mixture is ultrasonically oscillated and filtered, and talcum nanopowder and palm oil are added for homogenization treatment, so that the lecithin compound is obtained. The preparation method has the advantages of safety, environment-friendliness, low cost and good compatibility, and the obtained tableware has a good impact-resisting effect and a good anti-falling effect, and cannot be easily broken.

Description

technical field [0001] The invention relates to the technical field of melamine resin, in particular to a method for preparing melamine resin tableware that is not easily broken. Background technique [0002] Melamine resin has the characteristics of odorless, tasteless, non-toxic, and bright color. The tableware made of it can be used safely for a long time in the range of 30-120 °C. This kind of tableware is widely used in the fast food industry, staff canteens and children's because of its smooth surface, light weight, beautiful appearance, low temperature resistance (can be directly placed in the refrigerator), steaming resistance (boiling water cooking), pollution resistance, and not easy to break. catering industry and other fields. [0003] However, with the gradual increase in the consumption of melamine tableware, the shortcomings of melamine resin, such as easy breakage and poor impact resistance, have become more and more prominent, which has become a short board...
