Manufacturing method for degradable sponge product

Abstract

A manufacturing method for a degradable sponge product comprises the following steps: soaking, squeezing, yellowing, sticking, mixing, carrying out foam molding, washing, and preparing the degradable sponge product prepared from wood cellulose, wherein a), in the soaking process, two raw materials of sodium hydroxide and mixed pulp are mixed together in a dip vat; b) in the squeezing process, the soaked size is compressed to obtain an alkali cellulose block; c) in the yellowing process, carbon disulfide gas is introduced in the alkali cellulose block for yellowing to obtain xanthate; d) in the sticking process, xanthate, bamboo pulp, wood pulp and water are added in a kneading machine to be mixed to prepare an adhesive material; e) in the mixing process, the adhesive material, a sodium sulfate crystal and a toner ribbon are mixed to prepare a sponge mixture capable of being heated and foamed; f) in the foaming process, the sponge mixture is electrified, heated and coagulated to manufacture a sponge block.

Description

technical field [0001] The invention relates to a production method of a degradable sponge product made of wood pulp and bamboo pulp as mixed raw materials, and belongs to the technical field of preparation of degradable sponge products. Background technique [0002] Sponge is a general term for a porous material foam. According to the different raw materials used, various sponge products with different properties can be prepared. It has good water absorption and can be used for cleaning items. At present, the main sponge products on the market are synthetic resin sponges made of polyurethane or similar polymer materials through foaming. It has low cost, wide range of uses, and good water absorption effect. Those sponge mops are used as a common household cleaning appliance; however, the sponge products made of polymer materials have certain environmental pollution and cannot be degraded and regenerated; and after long-term use, they are easy to deteriorate, become hard and...

Problems solved by technology

At present, the main sponge products on the market are synthetic resin sponges made of polyurethane or similar polymer materials through foaming. It has low cost, wide range of uses, and good water absorption effect. Those sponge mops are used as a common household cleaning appliance; however, the sponge products made of polymer materials have certain environmental pollution and cannot be degraded and regenerated; and after long-term use, they are easy to deteriorate, Harden, reduce service life

[0003] With the improvement of people's living standards, people are increasingly pursuing environmentally friendly daily necessities. Therefore, when people become more and more aware of the environmental pollution of sponge products made of polymer materials and their impact on the human body, a new product using wood pulp raw materials , using its wood cellulose to make degradable and environmentally friendly sponge products through foaming technology has attracted more and more attention; Complicated and other defects, so the domestic application and use are less, and the application and promotion are subject to certain restrictions
