Problems solved by technology

"The cellulose chemical industry has high energy consumption, large amount of reagents, unstable product performance, and high cost. It is still difficult to produce cheap and high-quality products due to the lack of appropriate processing methods for cellulose.
The current production methods all have complex processes, high cost, water pollution, and high energy consumption. The main disadvantage of this type of material is that it is expensive

Embodiment 1

[0017] (1) Pour 30 kilograms of crushed sawdust into the banburying kneader, start the banbury kneader to work, then add 6% soda ash and 5 kilograms of water of the sawdust raw material and banbury and knead for 6 minutes.

[0018] (2) Pour the above banbury kneading material into the puffing extruder for puffing.

[0019] (3) The puffed extruded material is poured into the banburying kneader again, and 5% calcium stearate, 3% monoglyceride, 12% glycerol, 8% light calcium carbonate, 1 % preservatives, 12% polyvinyl alcohol, 4% whitening agent, 1% sulfur dioxide, banburying and kneading for 3 minutes, adding hydrochloric acid solution (concentration 36% and water 3 kg), banburying and kneading The PH value of the product is adjusted to neutral, and the moisture content is 40%-60%.

[0020] (4) After banburying, pour out and use a granulator to roll and compress into particles, which become plant plastic particle raw materials.

[0021] (5) The particles are added to the injec...

Embodiment 2

[0023] (1) 30 kilograms of crushed corn stalk fibers are poured into the started banburying kneader, then add 3% soda ash of corn stalk fiber raw material and 4 kilograms of water banburying and kneading for 4 minutes. Add hydrochloric acid solution, banbury kneading for 2 minutes, and adjust the pH value to 7.

[0024] (2) add 4% calcium stearate, 4% monoglyceride, 10% glycerin, 6% light calcium carbonate, 2% antiseptic, 15% polyvinyl alcohol, 3% whitening agent, banburying and kneading together for 2 minutes, moisture content 30%.

[0025] (3) Put the banburying kneaded material into the puffing extruder to extrude into tablets (the shape of the die head of the extruder changes), and then into the calender to be pressed into paper and film.

Embodiment 3

[0027] (1) 30 kg of crushed wheat straw fiber, 5% hydrogen peroxide, 5% hydrochloric acid and 5 kg of water were kneaded for 6 minutes, then added soda ash solution for 2 minutes, and the pH value was adjusted to neutral.

[0028] (2) Add 4% calcium stearate, 2% monoglyceride, 5% glycerin, 4% cake instant hair oil, 1% 4,4'-oxobisbenzenesulfonyl hydrazide , 1% preservative, and 25% polyvinyl alcohol are banburyed and kneaded together, and mixed with water.

[0029] (3) When the moisture content is 160%, it enters into microwave baking (the baking temperature is controlled at 120° C.), and becomes a foaming and shockproof plant fiber product.

Abstract

The invention relates to a manufacturing method of plant fibre products, which comprises the steps: pulverized substances containing textile plants are poured into a banburying kneader and chemical pretreatment solution is added, so the fibre pretreatment chemical modification is realized simultaneously when mechanical physics modifying is realized; after entering into an expansion extruder for expansion modification, the pulverized substances are added with various additives and fillings, which are banburied and kneaded together, and the banburying kneading substance is rolled into particles by a particle rolling machine; or plant fibre subjected to banburying kneading chemical modification and various additives and fillings are directly and together banburied and kneaded and then are extruded and produced to form particles or extrusion sectional materials by the expansion extruder; the produced particles or sectional materials can be used for producing plant fibre products of various types and performances and plant fibre products of sheets, sectional materials, paper, membranes, and the like by utilizing the prior plastic injection machine, extruder, blow moulding machine, rubber refining machine, calander, hot press, and equipment and technology principles of microwave and infrared, steam drying, and the like so as to replace plastic, plastic foam, woodworks, paper and membranes.

Description

Technical field: [0001] The invention relates to a production method of plant fiber products, in particular to a production method of making plant fibers into fully biodegradable plastic products. Background technique: [0002] For a long time, plant fibers have generally been used for incineration, weaving, papermaking, fodder and soil improvement. According to the 19th page of the book "Natural Polymer Modified Materials and Applications" published by Chemical Industry Press in 2006: "So far, no suitable method for melting and processing natural polymer materials has been found." "Biodegradable Polymer Materials And its application" book page 162 states: "Wooden materials do not have thermoplasticity, do not show thermal fluidity, and are insoluble in organic solvents", which limits the production and use of plant fibers. [0003] According to page 48 of the book "Biodegradable Polymer Materials and Their Applications", "Since people began to devote themselves to the rese...
