specific Embodiment approach 1

[0020] Specific implementation manner 1: This implementation manner is described in conjunction with FIG. 1 . This embodiment is made of cellulose powder, initiator, monomer and crosslinking agent extracted from waste flax or Chinese medicine residue and waste paper through chemical synthesis, and extracted from waste flax or Chinese medicine residue and waste paper by weight percentage The content of the cellulose powder is 8-17%, the initiator is 0.02-0.18%, the monomer is 83-89%, and the cross-linking agent is 0.06-0.4%.

specific Embodiment approach 2

[0021] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the cellulose powder extracted from discarded flax scraps or traditional Chinese medicine residue and waste paper is 10.5% by weight, the initiator is 0.1%, and the monomer is 89%. , The cross-linking agent is 0.4%.

specific Embodiment approach 3

[0022] Specific embodiment three: The difference between this embodiment and specific embodiment one is that the cellulose powder extracted from waste flax or traditional Chinese medicine residue and waste paper is 12%, the initiator is 0.05%, and the monomer is 87.75%. , The crosslinking agent is 0.2%.

Abstract

The invention relates to a water-retaining agent and a preparation method using discarded flax scraps or traditional Chinese medicine slag and waste paper as raw materials, and relates to a water-retaining agent and a preparation method thereof. It solves the problems that the existing water-retaining agent is difficult to be degraded by soil microorganisms, the cost of using starch and corn as raw materials is high, and the anti-mold performance is poor. The water-retaining agent of the present invention contains 8-17% of cellulose extracted from flax chips, waste paper or traditional Chinese medicine dregs, 0.02-0.18% of initiator, 83-89% of monomer, and 0.06-89% of cross-linking agent according to the percentage by weight. 0.4%. The preparation method is as follows: 1. Separate cellulose from flax scraps or traditional Chinese medicine residue, dry and crush it into cellulose powder; 2. Put the cellulose powder into a four-necked bottle, add water, stir, introduce nitrogen, and exhaust oxygen 1. Control the reaction temperature; 3. Add initiator, monomer and cross-linking agent, and react under nitrogen until the reaction liquid becomes viscous; 4. Dry and pulverize to obtain the water-retaining agent. The present invention has abundant raw material resources, low cost, few types of reagents used in similar synthesis methods, and little environmental pollution.

Description

technical field [0001] The invention relates to a water-retaining agent and a preparation method thereof, in particular to a water-retaining agent using flax scraps or traditional Chinese medicine residue and waste paper as raw materials and a preparation method thereof. Background technique [0002] In our country, there are a large amount of waste resources such as flax scraps, waste paper or traditional Chinese medicine residues every year. These waste resources contain a lot of cellulose. For example, the chemical composition of flax scraps is close to that of poplar, and the cellulose content is about 48%. In addition to ink and some additives in paper, the main component is also cellulose. At present, the method for preparing synthetic water-absorbing and water-retaining agents is to initiate chains first, then extend chains, and finally terminate chains, and cross-link with cross-linking agents to form a slightly cross-linked network structure. The existing water-abs...
