Problems solved by technology

[0003] The degradable daily utensils currently on the market have: grain tableware with the shortest decomposition period, which has the disadvantage of high production cost, consumes a large amount of grain, and is prone to mold; paper tableware with a long decomposition period has the disadvantage that the paper tableware is degraded during the degradation process. Harmful gases will be produced, which will pollute the atmosphere, and all cardboard must be wood pulp paper made by cutting down trees, and other papers cannot be used. Cutting down trees will destroy green resources, and papermaking will produce waste water, polluting the environment, Therefore, in essence, this is not a fundamental method to solve the problem; the most difficult to decompose is the degradable plastic tableware. Due to the limitations of the plastic material itself, whether it is biodegradation or photosensitive degradation, it is only a large piece of plastic. The point where it is broken into small pieces does not significantly improve the elimination of white pollution and the deterioration of the soil

Embodiment 1

[0023] 1) Mix 55 grams of 80-mesh plant fiber powder composed of bamboo powder, straw powder and tea powder with 45 grams of polylactic acid resin, stir at a high speed of 4500 rpm for 3 minutes, and then put the above mixture into a high-temperature and high-pressure mold for molding. Obtain a plant fiber shell with a temperature of 120°C and a pressure of 39209.8kPa;

[0024] 2) Polishing the surface of the plant fiber shell obtained in step 1);

[0025] 3) Spray water-based polyurethane on the surface of the plant fiber shell in step 2);

[0026] 4) After spraying, the product is baked in an oven at 120°C for 20-30 minutes, and the degradable plant fiber daily utensils are obtained.

Embodiment 2

[0028] 1) Mix 50 grams of 120-mesh plant fiber powder composed of bamboo powder, rice bran powder and tea powder, 44.5 grams of polylactic acid resin, 5 grams of water, 0.03 g of zinc stearate and 0.47 g of colorant, and mix at a high speed of 5000 rpm Stir for 5 minutes, then put the above mixture into a high-temperature and high-pressure mold for molding to obtain a plant fiber shell at a temperature of 160°C and a pressure of 50176kPa;

[0029] All the other steps are the same as in Example 1.

Embodiment 3

[0031] 1) Mix 70 grams of 160-mesh plant fiber powder composed of bamboo powder and tea powder, 25 grams of polylactic acid resin, 4.5 grams of water, 0.05 g of zinc stearate and 0.45 g of colorant, and stir at 5000 rpm for 5 minutes , and then put the above mixture into a high-temperature and high-pressure mold for molding to obtain a plant fiber shell at a temperature of 180°C and a pressure of 73725.4kPa;

[0032] All the other steps are the same as in Example 1.

Abstract

The invention discloses a degradable plant fiber daily-used utensil and a manufacturing method thereof. The degradable plant fiber daily-used utensil is manufactured from the following components by weight percent: 50-70 percent of plant fiber powder, 25-45 percent of polylactic resin, 0-8 percent of water, 0-0.05 percent of a release agent and 0-0.5 percent of a coloring agent, wherein the plant fiber powder is one type or a mixture of bamboo powder, straw powder, bran powder or tea powder. The degradable plant fiber daily-used utensil has the advantages that the utensil can be completely degraded, no environment pollution is caused, and the cost is low.

Description

technical field [0001] The invention relates to a degradable plant fiber daily vessel and a manufacturing method thereof. Background technique [0002] Daily utensils such as tableware and flower pots are the necessities of people's life. In recent years, with the rapid development of the economy, the pace of people's life is also accelerating, and the fast food industry has been able to develop sequentially, which has also caused the market's increasing demand for fast food tableware. [0003] The degradable daily utensils currently on the market have: grain tableware with the shortest decomposition period, which has the disadvantage of high production cost, consumes a large amount of grain, and is prone to mold; paper tableware with a long decomposition period has the disadvantage that the paper tableware is degraded during the degradation process. Harmful gases will be produced, which will pollute the atmosphere, and all cardboard must be wood pulp paper made by cutting ...
