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
The present invention relates to a kind of mainly is sponge product of forming with the bamboo pulp feedstock production and preparation method thereof.
Background technology
Sponge is the general name of foam, and is different according to used material, can generate the different sponge product of multiple performance.Traditional sponge product mainly is the synthetic resins sponge of adopting urethane and analogous material to process through foaming, and the chemical name of sponge is a polyurethane foam material, and it divides soft bubble (being used for furniture) and hard bubbles (being used for insulation) two kinds.
Be not sponge on the being seen in the market sponge mop stricti jurise, it is PVA collodion, and a kind of collodion that can absorb water especially can evaporate water automatically.This mop all squeezes out addle after mopping floor, and it is moistening for a long time to be filled maintenance with clear water at last, and to dry in the air just passable like this, need not all be immersed in the water.Notice that the sun is not exposed to the sun.If soak soft drawing again afterwards in next time in the hand with before stiff can being placed on earlier, otherwise cotton head fractures easily.It is fine to inhale soaking effect with this again after prevailing cotton thread mop mops floor earlier among this mop cooperation my family.
But above-mentioned sponge still is above-mentioned collodion all is to adopt macromolecule chemical material to process; Therefore have certain environmental pollution property itself with regard to product, can't regenerate, many sponge products are all followed the human body skin contact; Cause stimulation easily to human body skin; These sponge products are after long-time the use, and apt to deteriorate, hardening reduces its work-ing life; Worse is to use the back hard to manage, causes severe contamination, and because above-mentioned characteristic, thereby limited their use range, particularly European and American areas.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists; And a kind of can substitute traditional P VA sponge and PU sponge are provided; Adopting green pure natural raw material---bamboo is as main raw, bamboo pulp sponge product that clean environment firendly and regenerative power are strong and preparation method thereof.
The objective of the invention is to accomplish through following technical scheme; Bamboo pulp sponge product of the present invention; It is to select for use bamboo pulp as main raw material; Through after the immersion, squeezing, yellow, viscose glue, molding procedure, and add in the viscose glue operation and to contain fortifying fibre plain bamboo pulp or wood pulps auxiliary material, process by the methylcellulose of 92-94% weight percent, the S10 Mierocrystalline cellulose of 4.5-5.5% weight percent and the plain sponge product that constitutes of fortifying fibre of 0.5-3.5% weight percent.
Described sponge product is used MgCl after molding procedure
2Tenderizer softens, and makes this sponge product after softening, contain total amount 1.5-2.5% MgCl
2With 48-53% water.
A kind of preparation method of bamboo pulp sponge product, it mainly selects for use bamboo pulp as main raw material, this method comprises the steps: 1), soak operation, will contain the methylcellulose (C of 30-50% weight percent
