Problems solved by technology

[0002] People often use disposable tableware when they go out to eat. Most of the widely used disposable chopsticks are wooden chopsticks. For this reason, a large amount of wood is consumed every year. The speed of cutting down trees is much higher than the growth rate of new materials. After the trees are destroyed, it is difficult to recover for several years, which has brought great damage to my country's timber resources and ecological environment. From the perspective of economy and environmental protection, it is particularly important to develop a kind of degradable environmental protection chopsticks.

Embodiment 1

[0019] The biodegradable environmental protection chopsticks are made of the following raw material proportions by weight:

[0020]

[0021] The preparation technology of degradable environment-friendly chopsticks comprises the following steps:

[0022] (1) Clean the corn orange stalk fiber to remove the sediment and rot;

[0023] (2) Grinding the cleaned corn stalk fiber mixture into 40-80 mesh fines;

[0024] (3) Take 40% of the crushed corn stalk fiber in parts by weight, add 20% of starch, 10% of water, and 30% of amino molding powder and stir evenly to obtain plant fiber mixed powder;

[0025] (4) Inject the plant fiber mixed powder into the molded chopsticks mold, and press it in a hot press molding machine, the temperature is controlled at 125°C-143°C, after reaching the pressure, quickly deflate, and then pressurize for 20 seconds to make the product;

[0026] (5) The finished product is finished after the product is trimmed, sterilized and packaged.

Abstract

The invention discloses a degradable environmental protection chopstick. The chopstick is produced from 40-60wt% of vegetable fiber, 15-20wt% of starch, 20-40wt% of resin bonding powder and 2-10wt% of water. A production technology of the degradable environmental protection chopstick comprises the following steps: 1, cleaning the vegetable fiber to remove silt and rotten materials; 2, crushing the cleaned vegetable fiber; 3, taking 40-60wt% of the crushed vegetable fiber, adding 15-20wt% of starch, 2-10wt% of water and 20-40wt% of the resin bonding powder, and uniformly stirring to prepare vegetable fiber mixed powder; 4, injecting the vegetable fiber mixed powder into a molded chopstick die, and carrying out hot molding in a hot pressing molding machine at 125-143DEG C to obtain a product; and 5, finishing the product, disinfecting, and packaging to obtain the degradable environmental protection chopstick.
