Abstract

The invention provides a method for preparing a sanitary water absorbing material based on corn stalk seedlings. The method specifically comprises the following steps: crushing corn stalk seedlings, and performing primary screening; soaking powder obtained after primary screening, and performing suction filtration and washing; drying the washed corn stalk seedling powder in a baking oven; and performing secondary crushing on the dried corn stalk seedlings, and performing microwave treatment. The water absorbing material made of the corn stalk seedlings, which is provided by the invention, hasthe characteristics of being wide in raw material source, low in price, good in water absorption, and the like. Meanwhile, compared with villus pulp, the corn stalk seedlings need no acid or alkali inthe treatment process, are harmless to human bodies and are a novel environment-friendly material. Development and utilization of corn stalk can both meet national policies and alleviate the seriouswaste of corn stalk in China. The corn stalk is completely biodegradable, is free of pollution in the production process, is capable of replacing wool pulp and being introduced into the field of production of sanitary products, is capable of reducing environmental pollution, plays a role of environmental protection, and also achieves purposes of a good penetration effect and high water absorptionefficiency.

Description

technical field [0001] The invention belongs to the technical field of plastic packaging bags, and in particular relates to a method for preparing hygienic water-absorbing materials based on corn stalks. Background technique [0002] Corn stalks are natural raw materials, and about 350 million tons of corn stalks are produced in my country's agricultural production every year. However, less than 1 / 3 of it is used to return livestock feed and living fuel to the field. Most of the corn stalks are either piled up in the fields to rot naturally, or are directly burned in the field, which is not only a waste of energy, but also pollutes the environment. Corn stalks are biodegradable, widely sourced, cheap and environmentally friendly. Utilizing corn stalk resources can not only turn this resource advantage into an economic advantage, but also alleviate the waste of straw in my country. In addition, corn stalk itself is non-toxic and harmless, so its use in the manufacture of env...
