Problems solved by technology

The addition of these many chemical raw materials, on the one hand, makes the raw materials produce potential hazards to the operator during production, and the product will also cause new pollution risks to the environment during the degradation process. On the other hand, it increases the production cost of the product and loses competition in the market. force

Embodiment 1

[0027] An environmentally friendly plant fiber compressed board:

[0028] 60 parts of corn stalks, 20 parts of wheat straw, and 17 parts of waste wood were pulverized and mixed separately and passed through a 50-mesh sieve plate to obtain a plant fiber sieve mixture, and then 4 parts of oxidized starch, 2 parts of organic pigment and the total weight of the corresponding mixture were added Mix 5% water well and evenly to obtain the ready-to-use molding material; inject the ready-to-use molding material into the mold at 200°C, close and pressurize 350T, press down for 5s, lift the mold to exhaust for 3s, then press down again to close and keep the pressure for 500s, open The mold takes out the finished product.

[0029] After testing, the plant fiber compressed board obtained by the above method has a dense structure and can meet the requirements of non-load-bearing partitions or decorative panels.

Embodiment 2

[0031] A degradable and environmentally friendly plant fiber flowerpot:

[0032] Grind and mix 65 parts of wheat straw and 30 parts of wheat husk and pass through a 100-mesh sieve plate to obtain plant fiber sieve material, then continue to add 1 part of oxidized starch and 6% of the water corresponding to the total weight of the mixture and mix well to obtain a ready-to-use molding material ;Inject the ready-to-use molding material into the mold at 160°C, close and pressurize 20T, press down for 2s, lift the mold to exhaust for 1s, then press down again to close and keep the pressure for 20s, open the mold and take out the finished product.

[0033] Experiments show that the plant fiber flower pot obtained by the above method has a light and thin structure and a certain degree of flexibility. Under ordinary natural conditions, it can be naturally degraded within 2 to 3 months without residue, and can be used instead of a flower seedling cultivation bag. Nutrients are pre-adde...

Embodiment 3

[0035] A degradable and environmentally friendly plant fiber flowerpot:

[0036] Grind and mix 50 parts of wheat straw, 30 parts of corn stalk, and 15 parts of wheat husks and pass through a 80-mesh sieve plate to obtain a plant fiber sieve mixture, and then continue to add 2 parts of oxidized starch, 1 part of organic pigment and the total weight of the corresponding mixture Mix 3% water well and evenly to obtain the ready-to-use molding material; inject the ready-to-use molding material into the mold at 180°C, close and pressurize 100T, press down for 3s, lift the mold to exhaust for 2s, then press down again to close and keep the pressure for 240s, open The mold takes out the finished product.

[0037] Through experiments, the plant fiber flowerpot obtained by the above method has a light structure, is durable, and will not be damaged even if it is dropped from a height of 3 meters. Under open-air conditions, it can meet the normal use of at least 18 months without deforma...

Abstract

The invention relates to a degradable environment-friendly plant fiber product and a manufacturing method of the degradable environment-friendly plant fiber product, in particular to a flowerpot, tableware, a compressed panel or a tray made of the degradable environment-friendly plant fiber and the manufacturing method of the flowerpot, the tableware, the compressed panel or the tray made of the degradable environment-friendly plant fiber. The raw materials comprise plant fibers from crop straws, food processing wastes, annual wild plant stem parts, bamboos, and woods. The raw materials are added with modified starch and organic pigments to be molded at high temperature to produce the plant fiber product. The degradable environment-friendly plant fiber product has the advantages that the main raw materials can be completely from the wastes of agricultural products; the materials are simple; the cost is low; the product is green and environment-friendly and can be naturally degraded in a natural environment; the production method is simple and high-efficiency; and the product is mild in surface color, high in strength, waterproof and not easy to deform, and can be used for substituting the current products made of plastic, argil and wood, so that the plant fiber product is an ideal degradable environment-friendly plant fiber product.

Description

technical field [0001] The invention relates to a degradable and environment-friendly plant fiber product and a manufacturing method thereof, in particular to a degradable and environment-friendly plant fiber flowerpot, tableware, compressed board, tray and a production method thereof. Background technique [0002] my country is a big agricultural country. Along with the production of grain, a large amount of straw is produced as a by-product. At present, farmers all over the country burn one of them, and the ensuing large amount of smoke contains a large amount of harmful gases and suspended particles, which leads to a decline in air quality, endangers people's health, seriously hinders traffic, and leads to frequent accidents. [0003] In the existing plant fiber utilization technology, many other chemical materials need to be added, such as paraffin, grease, stearic acid, etc. need to be added in the degradable nutrient flowerpot disclosed in CN 02112063.3; Base cellulos...
