Abstract

The invention discloses disposable dissoluble plant fiber pressed tableware and the preparation method thereof, the tableware are made from the following materials : 100 portions of plant fiber with a water content of less than five percent, 30 to 40 portions of adhesive, 3 to 5 portions of mould release agent and 0.5 to 1.5 portions of waterproof agent, wherein the plant fiver comprises one or a plurality kinds of crop stalks, rice hulls, wheat hulls, bran coat and nut shell; the adhesive is natural soybean glue with a solidity of between forty and fifty percent. The plant fiber molded tableware is non-toxic to health, can be used as animal food or combustion-supporting material after being recycled and ground, and can be decomposed naturally, if not being recycled, to be organic fertilizer in nature to reach the purpose of no rubbish, no pollution, from nature and back to nature; the whole preparation process has no poison gas and waste fluid pollution, the products are resistant in cooling and water, good in thermal insulation property, strength and stiffness, has low production cost, simple technology and stable product quality.

Description

1. Technical field [0001] The invention belongs to a plant fiber molded tableware and a manufacturing method thereof. 2. Background technology [0002] Disposable plant fiber molded tableware is made of crushed plant fiber raw materials, mixed with adhesive, and then molded at high temperature. The raw materials of plant fiber are mainly crop straw, rice bran, wood flour, etc.; the adhesive mainly uses formaldehyde series urea-formaldehyde resin, phenolic resin or melamine resin adhesive. The raw material of the plant fiber is crushed and blended with an adhesive, and an appropriate amount of filler is added to be molded into a product. In the prior art, because the glue contains formaldehyde, the production process and products pollute the environment to varying degrees, and the production cost is high, and the products are not easy to degrade. 3. Contents of the invention [0003] The present invention solves the above-mentioned problems in the prior art, and provides ...
