Rice hull fiber synthetic resin powder and manufacturing technology of rice hull fiber products

Abstract

The invention relates to the field of chemical materials, in particular to a rice hull fiber synthetic resin powder and a manufacturing technology of rice hull fiber products; rice hulls are grinded to obtain rice hull powder; the hull powder is put into a mixer; cellulose, starch and water are added into the mixer to mix uniformly; then a mixture is taken out and cooled to obtain rice hull fiber powder; in addition, natural resin and lignin are put into a reactor; water is added into the reactor to stir uniformly and obtain slurry; then nano-silica is added into the slurry, continuously stirred uniformly and cooled; the rice hull fiber powder is added and continuously stirred; then the mixture is taken out after cooling to obtain paste materials; and then the paste materials are directly injected into a flash streaming drier to obtain the rice hull fiber synthetic resin powder; and the rice hull fiber synthetic resin powder can be used for manufacturing the rice hull fiber products such as tableware, toys, furniture, kitchen wares and so on, can be featured with hardness, high density, no toxicity, low cost and environmental protection, and also can be automatically degraded in the natural world to produce organic fertilizers; the products is featured with long service and wide market prospect.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a production process of rice husk fiber synthetic resin powder and rice husk fiber products. Background technique [0002] The existing tableware, furniture, kitchen utensils and other daily necessities on the market are made of plastic, wood, bamboo and other products. It destroys the water permeability of the soil, and wood products require deforestation and waste water pollution during the manufacturing process, so they are not very good environmental protection materials. [0003] In particular, most of the existing disposable tableware uses foamed plastics, and its foaming agent is Freon, which will destroy the ozone layer of the atmosphere, and it is extremely difficult to degrade. The invention patent publication CN1212312A discloses a degradable disposable tableware. Disclosed is permanent tableware and a manufacturing method thereof. The method uses crop husks or rods...

Problems solved by technology

[0002] The existing tableware, furniture, kitchen utensils and other daily necessities on the market are made of plastic, wood, bamboo and other products. It destroys the water permeability of the soil, and wood products require deforestation and waste water pollution in the manufacturing process, which is not a very good environmental protection material

[0003] In particular, most of the existing disposable tableware uses foamed plastics, and its foaming agent is Freon, which will destroy the ozone layer of the atmosphere, and it is extremely difficult to degrade. The invention patent publication CN1212312A discloses a degradable disposable tableware. Non-toxic tableware and a manufacturing method thereof, the method uses crop shells or rods as raw materials, and adds urea-formaldehyde resin and melamine to make it by hot pressing. The melamine used in the method is expensive, and the material will cause environmental pollution after degradation

[0004] China is the world's largest rice-producing country, with an annual output of about 195 million tons, accounting for 40% of the country's total grain output and 37% of the world's total rice output. The annual rice husk stripping amount reaches tens of millions of tons. It is a kind of agricultural waste, which is only used as fuel and feed filler in the vast rural areas. For a long time, due to the backward use of rice husk, it has caused a great waste of rice husk resources.

[0005] At present, the deep development and application of rice husk in developed countries in the world is quite extensive. In addition to being directly used as a culture material for edible fungi, as energy generation, beauty and cosmetics, and many other food and chemical products, the utilization of the above-mentioned rice husk is mostly It is through a complex technological process that the properties of the rice husk are changed, making it a new product to be used. The method of directly processing and utilizing the rice husk is really rare. It is difficult to find a method for the rice husk that does not change the properties of the rice husk itself. New uses that can be directly used on a large scale are a major problem for technicians
