Embodiment 1

[0025] The raw materials are prepared according to the following parts by weight: the rice husk is 10 parts, cellulose is 3 parts, water is 3 parts, polylactic acid is 2 parts, and starch is 5 parts. The polylactic acid is obtained by saccharifying corn starch to obtain glucose, then fermenting glucose and a certain strain to produce high-purity lactic acid, and then synthesizing a certain molecular weight through a chemical synthesis method.

[0026] The specific production method steps are as follows:

[0027] (1) Grind rice husk into 50 mesh rice husk powder;

[0028] (2) Put the rice husk powder of step (1) into a high-temperature high-speed mixer, add cellulose and inject water during the mixing process, where the temperature of the mixing environment is 50℃, then take it out and cool it to make rice husk fiber Flour, the moisture content of the rice husk fiber flour shall not exceed 10%;

[0029] (3) Put polylactic acid and starch into the reactor, heat up to 150°C and ...

Embodiment 2

[0034] The raw materials are prepared according to the following parts by weight: the rice husk is 2 parts, cellulose is 1 part, water is 1 part, polylactic acid is 5 parts, and starch is 10 parts. The polylactic acid is obtained by saccharifying potato starch to obtain glucose, then fermenting the glucose and a certain strain to produce high-purity lactic acid, and then synthesizing a certain molecular weight through a chemical synthesis method.

[0035] The specific production method steps are as follows:

[0036] (1) Grind rice husk into 200 mesh rice husk powder;

[0037] (2) Put the rice husk powder of step (1) into a high-temperature high-speed mixer, add cellulose and inject water during the mixing process, where the temperature of the mixing environment is 100°C, then take it out and cool it to make rice husk fiber Flour, the moisture content of the rice husk fiber flour shall not exceed 10%;

[0038] (3) Put polylactic acid and starch into the reactor, heat up to 220...

Embodiment 3

[0043] The raw materials are prepared according to the following parts by weight: the rice husk is 5 parts, cellulose is 3 parts, water is 2 parts, polylactic acid is 1 part, and starch is 2 parts. The polylactic acid is obtained by saccharifying tapioca starch to obtain glucose, then fermenting glucose and a certain strain to produce high-purity lactic acid, and then synthesizing a certain molecular weight through a chemical synthesis method.

[0044] The specific production method steps are as follows:

[0045] (1) Grind rice husk into 150 mesh rice husk powder;

[0046] (2) Put the rice husk powder of step (1) into a high-temperature high-speed mixer, add cellulose and inject water during the mixing process, where the temperature of the mixing environment is 150°C, then take it out and cool it to make rice husk fiber Flour, the moisture content of the rice husk fiber flour shall not exceed 10%;

[0047] (3) Put polylactic acid and starch into the reactor, heat up to 200°C ...

Abstract

The invention relates to a rice husk fiber and polylactic acid synthesized resin particle, which comprises the following raw materials by weight: 2-10 parts of rice husk, 1-5 parts of cellulose, 1-3 parts of water, 1-5 parts of polylactic acid, and 2-10 parts of starch. The specific production method includes the steps of: firstly grinding the rice husk into rice husk powder, then putting the powder into a high mixing machine, adding water and cellulose and mixing the materials evenly; in addition, putting polylactic acid and starch into a reaction kettle, firstly conducting heating and stirring the materials evenly, then performing cooling, and adding the rice husk fiber powder into a reaction kettle and further performing stirring to obtain a pasty material; and finally injecting the material into a screw extruder, and carrying out screw extrusion drawing to obtain golden yellow strips. The finished product injection molded from the rice husk fiber and polylactic acid synthesized resin particle has the characteristics of hardness, high density, no toxicity, low cost, environmental protection and the like, can degrade into organic fertilizers in nature by itself, also has more meticulous and exquisite appearance, and has good toughness, is more drop resistant, and has prolonged service life.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to rice husk fibers and polylactic acid synthetic resin particles and a production method thereof. 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] 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 ...
