Problems solved by technology

[0003] At present, the raw materials used for wood-plastic composite material filling mainly come from bamboo, pine wood, camphor wood, straw and waste paper, etc. The wood-plastic composite materials prepared by the predecessors with these natural plant fiber materials are mainly used for pallets, packaging, furniture, In the fields of automobiles, gardens, and construction, there are few researches on the application of wood-plastic composite materials in catering utensils, and there are no related reports on the use of tea-plastic composite materials to prepare catering utensils

Abstract

The invention relates to tea plastic tableware and a preparation method thereof. The preparation method of the tea plastic tableware comprises the following steps: preparing materials, mixing, preparing tea plastic powder and preparing tea plastic tableware. According to the preparation method of the tea plastic tableware, the use amount of high-density polyvinyl resin can be decreased by taking tea side products as stuffing, the white pollution can be effectively reduced, and the mechanical performance of the tea plastic tableware can be enhanced. The tea plastic tableware produced by adopting the method is made of tea plastic composite materials, and internally has a complicated network structure, and the stability of the tea plastic tableware product can be guaranteed. Furthermore, the tea side product contains cellulose, crude protein, tea polyphenol, amino acid, saponin, aromatic substances and the like, the tea plastic tableware prepared by taking tea side products as stuffing has antibacterial action to certain extent, and can emit pleasant tea aroma.

Description

technical field [0001] The invention relates to a catering utensil and a preparation method thereof, in particular to a tea-plastic catering utensil using tea by-products as natural fiber fillers and a preparation method thereof. Background technique [0002] China is the hometown of tea, and it is also a big tea production and consumption country. Tea by-products such as tea stems, tea dust, tea dregs and tea prunings will be produced during the tea production process. Most of these tea by-products are discarded. These by-products are rich in natural plant fibers and are good filling materials for wood-plastic composite materials. [0003] At present, the raw materials used for wood-plastic composite material filling mainly come from bamboo, pine wood, camphor wood, straw and waste paper, etc. The wood-plastic composite materials prepared by the predecessors with these natural plant fiber materials are mainly used for pallets, packaging, furniture, In the fields of automob...
