Abstract

The invention relates to the technical field of environmentally-friendly tableware, and discloses a recyclable environmentally-friendly bamboo fiber tableware. The recyclable environmentally-friendlybamboo fiber tableware comprises, by weight, 100-150 parts of enzymolytic bamboo fibers, 50-70 parts of deionized water, 8-15 parts of kaolin, 15-20 parts of sodium silicate, 25-35 parts of thermosetting composite resin, 5-10 parts of starch and 12-15 parts of aluminum oxide powder. The enzymolytic bamboo fibers are prepared by the following steps: soaking bamboo chips in a sodium hydroxide solution for 1-3 h, washing the bamboo chips with deionized water, soaking the bamboo chips in a hydrochloric acid solution for 1-3 h, washing the bamboo chips with deionized water, cooking the bamboo chipsin a high-pressure steamer at 110-130 DEG C for 50-70 min to obtain cooked bamboo chips, soaking the cooked bamboo chips in a lytic enzyme solution for 2-3 h, and spin-drying the cooked bamboo chipsin a centrifugal machine to obtain the enzymolytic bamboo fibers. The recyclable environmentally-friendly bamboo fiber tableware is nontoxic, harmless, green, healthy, biodegradable and convenient torecycle, and has the advantages of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the technical field of environment-friendly tableware, in particular to recyclable and environment-friendly bamboo fiber tableware. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good air permeability, instant water absorption, strong It has the characteristics of abrasion resistance and good dyeability, and at the same time has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. It is a natural and environmentally friendly green fiber in the true sense. [0003] Existing catering utensils adopt food-grade plastics, pottery, glass etc. to make mostly, also have to process with natural bamboo main body. With the increasing awareness of environmental protection, renewable natural plant fibers are widely used in the field of material tech...
