Embodiment approach 1

[0019] Embodiment 1 A plant fiber product that can be degraded within three months and cannot pass the microwave oven or dishwasher test

Embodiment 1

[0021] According to the following method, the fully degradable plant fiber material product of the present invention is made:

[0022] (1) the bamboo chip fragments are pulverized to 60 order fineness with pulverizer, and it is subsequent use to take by weighing 60kg powder;

[0023] (2) Add 5kg polyvinyl alcohol, 10kg polycaprolactone and 10kg HPMC (take HPMC 2KG, add 5KG of 90 ℃ water to boil for an hour, get 5KG aqueous solution) in the container, add above-mentioned bamboo powder and 15kg after mixing Natural starch, stirred and added with 10kg of zinc stearate, dried and dehydrated at 70°C for 3 hours, then crushed and ground into fine powder;

[0024] (3) Heat the above mixture with a thermoforming machine at a temperature of 150°C and 10kg / cm 2 Under the pressure, die-cast for 2-5 minutes, release the steam once at 1 minute, and continue to press for 1-8 minutes. Those skilled in the art can determine the time of die-casting according to the required thickness;

Embodiment 2

[0029] According to the following method, the fully degradable plant fiber material product of the present invention is made:

[0030] (1) Wooden scrap is pulverized to 40 order fineness with pulverizer, takes by weighing 40kg powder for subsequent use;

[0031] (2) Add 5kg polycaprolactone in the container, add the above-mentioned bamboo powder and 40kg modified starch after mixing, stir and add cadmium toner and permanent yellow of 5kg zinc stearate and 2kg, dry and dehydrate at 60°C 5 hours, and then crushed and ground into a fine powder.

[0032] (3) Put the above mixture at a temperature of 160°C and 30kg / cm by a die-casting machine 2 Under the pressure, die-cast for 2-5 minutes, release the steam once at 1 minute, and continue to press for 1-8 minutes. Those skilled in the art can determine the time of die-casting according to the required thickness;

[0033] (4) Use manual flashing or electric grinding wheel to beat the flashing, and polish it to smooth;

Abstract

The invention relates to a completely degradable product and a manufacturing method thereof. The product comprises the compositions in percentage by weight: 40 to 80 percent of vegetable fiber powder, 2 to 40 percent of adhesive, 5 to 15 percent of release agent and 5 to 40 percent of starch. Preferably, the product also contains 1 to 2 percent of toner. The technology can make full use of various natural vegetable fiber materials and increases the using value of raw materials while reducing environmental pollution; the manufactured product is completely biodegradable and nontoxic; moreover, the product has lower manufacturing cost and different types and is suitable for daily use. The manufacturing method essentially and structurally changes the configuration of vegetable fiber and ensures that each composition has excellent processing flowability. Technically, the manufactured product reaches relevant international testing standards (such as American/European food testing standards) and can be tested through dishwasher and microwave oven; therefore, the product is applicable for industrial automatic production.

Description

technical field [0001] The present invention relates to a fully degradable product and its manufacturing method, more specifically, to a completely degradable product made of plant fiber material and its manufacturing method. Background technique [0002] With the continuous development of the global industrialization process, environmental pollution has become an important issue that cannot be ignored, and the so-called white pollution is the most worrying. Disposable plastic products (including foamed plastic lunch boxes, utensils, packaging materials and thin plastic bags, films, agricultural mulch films, etc.) are mostly discarded in the environment due to the lack of recycling value after use. Among them, they are mainly concentrated around scenic tourist areas, on both sides of rivers and roads, in farmland, lakes and ponds, and in every corner of towns, which not only destroys the landscape and causes "visual pollution", but also The characteristics of being difficul...
