preparation example Construction

[0007] (3) Preparation of adhesive (parts by weight):

[0008] Calcium stearate 0.4-0.6; sodium calcium carboxymethylcellulose 0.2-0.8; vegetable starch (potato starch or corn starch or wheat starch) 1.5-2. Mix the powders of the three substances for use;

[0009] (4) softener: chemically pure glyceryl stearate;

[0010] (5) Antifungal agent: chemically pure calcium propionate;

[0011] (6) Foaming agent (parts by weight): sodium bicarbonate 0.5-0.8, urea 0.2-0.6 powder mixing stand-by;

[0012] (7) Waterproofing agent: chemically pure tetramethylpolysiloxane;

[0013] Among them, calcium stearate is a mold release agent, which makes the surface of the finished product smooth; starch is a wet strengthening agent, which makes the product maintain a certain strength when it comes out of the mold in a wet state; and this adhesive can directly interact with the cellulose molecule The bond part and support part are combined to partially generate chemical bond and hydrogen bond,...

example 1

[0021] (1) Preparation of binder: 200g of calcium stearate; 200g of sodium calcium carboxymethyl cellulose; 1600g of potato starch, the powders of the three materials are mixed for later use, wherein the potato flour can be replaced by cornstarch or wheat starch;

[0022] (2) The preparation of blowing agent: sodium bicarbonate 60g, urea 30g powder mixes stand-by;

[0023] (3) Treatment of plant fibers: chop 1 kg of dry straw into 2-4 cm long, put it into a sealable container, add 2 kg of water containing some kind of mold, soak the straw in it for degradation, and then seal and put into the swinging bed. After 7 days, take out the soaked rice straw and beat it with a beater; the slurry is dehydrated and precipitated by a centrifuge at a speed of 600 rpm to obtain a plant fiber raw material;

[0024] (4) Add 20g of adhesive, 10g of softening agent, 10g of antifungal agent, 15g of foaming agent, and 10g of water repellent in sequence in (3), stir and mix;

Embodiment 2 5

[0028] Except that plant fibers such as wheat orange stalks, bean stalks, asparagus grass, and corn stalks are used instead of straw, other conditions are the same as in Example 1.

[0029] Plant fiber packaging materials with similar properties can also be obtained.

Abstract

The invention relates to an environmentally-friendly plant fiber packing material, and belongs to the field of packing materials. The environmentally-friendly plant fiber packing material is preparedby the following steps: putting plant fibers of agricultural waste straws, wheat stalks, bean stalks, devil's rush herb, corn stalks and the like into a closed container, adding water containing one or more of fungi into the container to soak the plant fibers in the water to be degraded, and then sealing the container and shaking the container for 5 to 7 days; taking the plant fibers out and beating the plant fibers; preparing the plant fibers, adhesive, softener, mildew-proof agent, foaming agent and waterproof agent in a weight ratio of (50-70): (1-2): (0.5-1): (0.5-1): (1-2): (0.5-1); bulking the materials into granules through bulking equipment, and blowing the granules into different models according to the packing requirements; or directly pressing the prepared materials into different packing models on a hot press. The environmentally-friendly plant fiber packing material has the advantages that the material totally uses the plant fibers of the straws, wheat stalks, bean stalks,devil's rush herb, corn stalks and the like, so the source is wide, and the price is low; the production process has no three wastes and does not influence the environment; the product is in accordance with the requirements of environmentally-friendly packing materials on light weight, pressure resistance, seismic resistance, moisture prevention and water prevention; and after discarding, the packing material can be naturally degraded, so the packing material is favorable for environmental protection.

Description

technical field [0001] The invention relates to a packaging material, in particular to an environment-friendly plant fiber packaging material, which belongs to the field of packaging materials. Background technique [0002] With the rapid development of industry and the popularization and trial of various electronic and electrical products, the demand for product packaging materials is increasing. At present, the packaging materials of industrial products widely used in the market are foamed plastic products. Although foamed plastics are low in cost, convenient in process, and have good cushioning performance, they are difficult to degrade, so they will cause "white pollution" to the environment, thus Threats to the living environment of human beings themselves; foreign countries have banned the acceptance of my country's export products packaged in foam plastics. Now, the impact of plastic products on the ecological environment has attracted great attention from various cou...
