Preparation method of biodegradable moisturizing vegetable packaging fiber paper

Abstract

The invention discloses a preparation method of biodegradable moisturizing vegetable packaging fiber paper. The preparation method comprises the following steps: (1) fibers are subjected to enzymolysis of cellulase, and then are further degraded in water at room temperature, and the degraded fibers are stricken into a slurry; (2) starch is dissolved in an aqueous NaOH solution, then succinic anhydride and a prepared mixed solution of silane coupling agent and absolute ethanol are added, and modification treatment is performed, so as to obtain modified starch; (3) attapulgite and acrylic acid are compounded, and then the compounded mixture is mixed with the modified starch; and (4) the slurry obtained in step (1) and the mixture obtained in step (3) are mixed, and then a crosslinking agentis added to cause slight implosion, then the slurry obtained after the completion of the implosion reaction is copied into base paper, and the base paper is vacuum dried, so as to obtain the biodegradable moisturizing vegetable packaging fiber paper. According to the preparation method of the biodegradable moisturizing vegetable packaging fiber paper, cross-linking between the acrylic acid and thestarch is used, and carboxyl groups introduced by the acrylic acid react with hydroxyl groups of the fibers, so that the moisturizing ability is improved, production cost is reduced, and the processis simplified; and the prepared fiber paper can perform biodegradation by using starch as a carbon base.

Description

technical field [0001] The invention relates to fiber paper, in particular to a preparation method of biodegradable moisturizing vegetable packaging fiber paper. Background technique [0002] At present, the hygroscopic materials used in products in the field of hygiene products are mostly composed of one or two layers of non-woven fabrics and a layer of polymer or other water-absorbing materials. Functional fiber with water retention performance can absorb water dozens to hundreds of times its own weight, and has a strong water retention capacity, and is not easy to lose water under high temperature and pressure. Super absorbent fiber has the following advantages [(1) large surface area, fast water absorption; (2) gel does not flow after water absorption, and can maintain the strength and integrity of absorbent fiber: (3) simplifies the manufacturing process of sanitary products; (4) ) can be blended with other fibers to make products using general fiber processing machine...

Problems solved by technology

[0003] In the article "Preparation and Application of Fiber and Hydrogel Composite Materials", Ni Jianping used acrylic acid as a monomer, N,N'-methylenebisacrylamide as a crosslinking agent, added a small amount of microcrystalline cellulose, and UV-induced Preparation of polyacrylic acid / microcrystalline cellulose composite superabsorbent resin, crushed and sieved superabsorbent resin powder larger than 120 meshes is used to prepare superabsorbent paper-based materials with a "sandwich" structure through lamination and composite technology, and the water absorption effect is remarkable However, in the process of laminating and compounding the superabsorbent paper, it is necessary to apply adhesive to the paper, and the change of the coating structure and the migration of the adhesive will affect the strength of the paper during the drying process.
