Bamboo pulp sponge product and preparation method thereof

Abstract

The invention discloses a bamboo pulp sponge product and a preparation method thereof. Bamboo pulp is used as a main raw material. The method comprises the following steps of: 1) soaking, namely adding sodium hydroxide solution into the bamboo pulp raw material at the temperature of between 25 and 35 DEG C, and reacting the mixture to generate AC alkali cellulose and water; 2) squeezing, namely squeezing the AC alkali cellulose through a squeezer, filtering the redundant sodium hydroxide solution to form cakes, and crushing the cakes into granules or blocks of 5 to 10 millimeters; 3) yellowing, namely reacting the granular or block alkali cellulose and carbon disulfide at the temperature of between 25 and 40 DEG C under vacuum to obtain xanthate; 4) gluing, namely adding bamboo pulp or wood pulp into the xanthate, and soaking the mixture into water to form a glue; and 5) molding, namely adding an inorganic acid salt pore-forming agent of alkali metal or alkaline earth metal into the glue, standing the mixture for 5 to 7 hours after mixing, then putting the mixture into a mold for molding, condensing by using current and foaming to prepare the sponge product consisting of 92 to 94 weight percent of methylcellulose, 4.5 to 5.5 weight percent of S10 cellulose and 0.5 to 3.5 weight percent of reinforced cellulose. The sponge product has the characteristics of strong water absorption, soft texture, strong dire and oil removing capability, long-time storage and accommodation, unchanged quality, pure natural and unpolluted product and the like.

Description

Technical field [0001] The invention relates to a sponge product mainly prepared from bamboo pulp raw materials and a preparation method thereof. Background technique [0002] Sponge is a general term for foam. According to the different materials used, a variety of sponge products with different properties can be produced. Traditional sponge products are mainly synthetic resin sponges made of polyurethane and similar materials by foaming. The chemical name of the sponge is polyurethane foam material. It is divided into soft foam (used for furniture) and rigid foam (used for heat preservation). Kind. [0003] The sponge mop currently seen on the market is not a sponge in the strict sense. It is called PVA colloid, a kind of colloid that can absorb water and can automatically evaporate water. This kind of mop squeezes out all the dirty water after mopping the floor, and finally it is filled with clean water to keep it moist for a long time, just leave it in the air without soaking...

Problems solved by technology

[0004] However, both the above-mentioned sponge and the above-mentioned collodion are made of high-molecular chemical materials, so the product itself has certain environmental pollution and cannot be regenerated. Many sponge products are in contact with human skin, which is easy to cause damage to human skin. After a long time of use, these sponge products are easy to deteriorate and harden, reducing their service life; what's worse is that they are difficult to handle after use, causing serious pollution, and due to the above characteristics, their scope of use is limited, especially Europe and the United States
