Abstract

The invention discloses a preparation method of impact-resistant melamine resin dishware, which comprises the following steps: granulesten, wool fibers and absolute ethyl alcohol are uniformly mixed,added with sodium persulfate, stirred, ultrasonically oscillated, filtered, added with nano-diatomite and corn oil and homogenized, so that a mixed material is obtained; and melamine resin, coconut shell fibers, tetraethoxysilane, calcined kaolin, stearic acid, antioxidant and the mixed material are uniformly mixed, added with a release agent and a hardener, uniformly mixed, ground, screened and hot-pressed to be shaped, so that the impact-resistant melamine resin dishware is obtained. The preparation method of the impact-resistant melamine resin dishware proposed by the invention is safe, environmentally friendly, low in cost and highly compatible, and the obtained dishware has a good impact-resistant effect and a good anti-crash effect and cannot be easily broken.

Description

technical field [0001] The invention relates to the technical field of tableware, in particular to a preparation method of impact-resistant melamine resin tableware. Background technique [0002] Melamine resin tableware, also known as melamine tableware, is a new type of tableware that has emerged in recent years. Melamine plastic tableware is based on melamine formaldehyde resin and is molded into tableware. It is widely used at present, but the technical problems of melamine resin tableware are easy to break and impact resistance cannot meet the demand, which need to be solved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a preparation method of impact-resistant melamine resin tableware, which is safe and environmentally friendly, low in cost, and good in compatibility. The resulting tableware has good impact resistance, is not easy to break, and has good drop resistance. [000...
