preparation example Construction

[0013] The invention provides a kind of preparation method of high-strength aviation garbage bag, comprising:

[0014] 1) mixing raw materials with lime water and cooking to make pulp;

[0015] 2) The pulp is washed, blanched, beaten, fished, squeezed and baked to make high-strength paper;

[0016] 3) Process high-strength paper into high-strength aviation garbage bags;

[0017] Among them, raw materials include bamboo, bark, hemp, cotton stalks, silk, asbestos, white carbon black, saponins, iron leaves, diatomaceous earth, bran, palm palm, bamboo shoots, starch, galangal, cohosh, cloves and magnolia.

[0018] In the present invention, the specific type of bamboo can be selected in a wide range, but in order to make the high-strength aviation garbage bag have more excellent mechanical properties and anti-mold ability, preferably, bamboo is selected from moso bamboo, bitter bamboo and Ci bamboo one or more of .

Embodiment 1

[0030] 1) At 150°C, mix the raw material with lime water (calcium hydroxide content is 0.17% by weight) and cook for 5 days to obtain pulp; wherein, the mass ratio of raw material to lime water is 1:4, and the raw material contains Moso bamboo, green sandalwood bark, hemp, cotton stalks, silk, asbestos, white carbon black, saponins, iron leaves, diatomaceous earth, bran, palm palm, bamboo shoots, wheat starch, galangal, cohosh, cloves and magnolia (The weight ratio of each substance is 100:30:25:7:4:1.5:1:3.5:6:2:10:5:15:2:4:2:3:2).

[0031] 2) washing the pulp until no spoils are washed out to obtain the washed pulp;

[0032] 3) Sun-whitening the above-mentioned washed pulp for two months at 25° C. to obtain sun-whitened pulp;

[0033] 4) pounding the above-mentioned sun-whitened pulp until it becomes a mud paste to obtain a mud paste pulp;

[0034] 5) placing the above-mentioned mud paste pulp in water and carrying out paper extraction to obtain wet paper;

[0035] 6) Bak...

Embodiment 2

[0038] 1) At 200°C, mix the raw material with lime water (the content of calcium hydroxide is 0.18% by weight) and cook for 6 days to obtain pulp; wherein, the mass ratio of raw material to lime water is 1:5, and the raw material contains Bitter bamboo, mulberry bark, flax, cotton stalks, silk, asbestos, white carbon black, saponins, iron leaves, diatomaceous earth, bran, palm palm, bamboo shoots, potato starch, galangal, cohosh, cloves and magnolia ( The weight ratio of each substance is 100:40:30:10:5:2:1.5:4:8:1:5:3:9:4:7:3:4:3.5).

Abstract

The invention discloses a high-strength aviation refuse bag and a preparation method thereof. The preparation method comprises the following steps: (1) mixing raw materials and lime water and cooking to prepare paper pulp; (2) carrying out washing, bleaching, knocking, paper dragging, squeezing and paper baking on the paper pulp to prepare high-strength paper; (3) processing the high-strength paper into the high-strength aviation refuse bag; the raw materials comprise bamboo, bark, fiber, cotton stalk, silk, asbestos, white carbon black, Chinese honeylocust fruit, folium cycas, kieselguhr, bran, palm fiber, bamboo shoot skin, starch, galangal, cimicifugae foetidae, clove and flower bud of lily magnolia. The high-strength aviation refuse bag prepared by the method has excellent mechanical strength and antifungal capability, and meanwhile, the raw materials in the method are easy to obtain, so that the high-strength aviation refuse bag can be produced in mass in an industrial level.

Description

technical field [0001] The invention relates to a garbage bag, in particular to a high-strength aviation garbage bag and a preparation method thereof. Background technique [0002] Garbage bags, as the name suggests, are bags for garbage. A small bag brings great convenience to thousands of households, and it also provides an important guarantee for environmental protection, and is even conducive to garbage recycling and classification. According to the material classification, garbage bags can be divided into plastic garbage bags and paper garbage bags. Plastic garbage bags are widely used due to their waterproof, high mechanical strength and light weight. However, plastic garbage bags are easy to cause environmental pollution and their usage is gradually increasing. reduce. In response to the defects of plastic garbage bags, the number of paper garbage bags is gradually increasing, especially in aircraft with high environmental requirements, paper garbage bags are the onl...
