Problems solved by technology

It can be seen that the degradable disposable tableware still cannot be completely degraded, and has the problems of low degradation rate, high production cost, and toxicity (such as "Manufacturing Process of Degradable Disposable Tableware" of Chinese Patent Publication No. CN1363626A And Chinese Patent Publication No. CN1407021A "A kind of degradable disposable tableware and its method using corn stalks as the main raw material" are all the same)

Embodiment Construction

[0014] A method for preparing disposable fully degradable tableware with straw-based aldehyde-free and plastic-free materials of the present invention is a kind of aldehyde-free and plastic-free material prepared by modifying straws as the main raw material to produce disposable fully degradable tableware. Process method for degrading tableware.

[0015] The first is to carry out the compound modification treatment of straw materials; the treatment method consists of three steps of material kneading and drying treatment, pulverization and milling aid grinding modification, inoculation fermentation and drying treatment. The material kneading and drying process described therein is to select one or more kinds of grass plants such as corn stalks, bean stalks, wheat stalks, cotton stalks, rice straws and their seed body shells as the required straw materials, and remove the stalks in the straw first. Impurities, enzymes and dust, and then the required materials are kneaded into 4c...

Abstract

The invention discloses a method for preparing disposable and fully-degradable tableware from a straw-based formaldehyde-free and plastic-free material. A straw material composite modifying treatmentprocess comprises material rubbing and drying treatment, grinding for power preparation, grinding aiding and modifying as well as inoculation, fermentation and drying treatment, composite modified active straw powder obtained with the process is subjected to cold mixing and compounding with a forming and curing aid prepared with a forming and curing aid preparation process, and compression moldingis performed. The raw materials are wide and available, a polycondensation reaction, lignin dissolution and self polycondensation, crosslinking and gluing effects are produced in the preparation process, firm interface bonding is formed, and the product has the characteristics of being higher in mechanical strength, water repellence, oil repellence and high-temperature resistance, fully-degradable, non-toxic, high in weather resistance and recyclable after use; the preparation process of the product is simple, reasonable in design, convenient to operate and control, low in production cost, environmentally friendly, energy-saving and efficient, development of circular economy is improved, and economic and social benefits are remarkable.

Description

technical field [0001] The invention relates to a preparation method, in particular to a method for preparing formaldehyde-free and plastic-free disposable fully degradable tableware by using straw as a main raw material through composite modification. Background technique [0002] With the rapid development of my country's economy, people's living standards are constantly improving, and the pace of life is also accelerating. The fast and convenient disposable tableware has also been widely used in the catering industry, but the disposable foamed plastic tableware, paper tableware, and washed PP film-coated ceramic component tableware that are commonly used at present are not biodegradable because of their materials. Including the waxy layer on the inner wall of the tableware, harmful ingredients such as detergent and formaldehyde, not only will cause huge pollution to the environment, but also cause certain damage to the human body, thus seriously restricting the green and h...
