Abstract
The invention provides a manufacturing method of a moisture preserving sponge. The moisture preserving sponge is mainly made of wood pulp and/or bamboo pulp. The manufacturing method comprises the steps of dipping, squeezing, aging, yellowing, preparaing of a viscose material, heating, foaming and forming; after the sponge is cut into blocks and washed, blocky sponge products are manufactured; after washing, sufficient magnesium chloride solution absorbing and storing are conducted, so that the blocky sponge products containing the magnesium chloride solution of the concentration of 10%-15% are obtained; after absorbing and storing of the magnesium chloride solution are stopped, redundant magnesium chloride solution is squeezed out through squeezing or compressing, and finally the blocky sponge products containing the magnesium chloride solution of the concentration of 34%-46% is obtained. The temperature of the magnesium chloride solution absorbed and stored by the blocky sponge products ranges from 32 DEG C to 38 DEG C. The washing process comprises the steps of conducting strong salt washing with weak salt, conducting acid pickling for neutralizing salt and conducting bleaching washing through decolorizer. The moisture preserving sponge has the advantages of being simple and reliable in manufacturing process, capable of maintaining a certain moisture content and the like.
Description
Technical field
What the present invention relates to is the making method of a kind of moisturizing sponge, and especially a kind of wood cellulose makes the making method of degradable moisturizing sponge, belongs to the preparing technical field of sponge.
Background technology
Sponge is a kind of porous material, has good water-absorbent, can be used in clean article.The sponge that people commonly use mainly comprises: two kinds that are made up respectively of wood cellulose fibers or expanded plastic polymkeric substance.Because the sponge cost made with expanded plastic polymkeric substance is low, of many uses, soaking effect is good, is generally used to all trades and professions, especially makes those common sponge mop, and as the cleaning appliance that a kind of family commonly uses; But the sponge products that this employing macromolecular material is made, itself raw material has certain environmental contamination, regeneration of cannot degrading; And after life-time service, apt to deteriorate, hardening, reduce work-ing life.
Along with the raising of people's living standard, people more and more pursue environmental protection daily necessities, therefore make sponge products there is environmental pollution and after human body is had an impact when people more and more understand macromolecular material foaming, a kind of employing wood pulps and/or bamboo pulp raw material, utilize their wood cellulose to make degradable environment-friendlysponge sponge goods through foam process and be more and more subject to people's attention; Although it is high to there is raw materials cost in the sponge product that this wood cellulose fibers is made, the defects such as manufacture craft relative complex, but because this is that a kind of environment-friendly materials are made, little to environmental influence, can regenerate and not have an environmental pollution, long service life, thus general high-grade life appliance still more selects this sponge products; Although at present application at home and usage quantity are no more than inexpensive macromolecule foaming sponge products, but the trend increased gradually, but for abroad, as these developed countries of American-European countries, then almost there are very large use and application quantity, therefore, the sponge product export volume made of this wood cellulose fibers is still larger.
The sponge products sold in the market is drying regime substantially, the sponge product of original bulk because of dry after strain, thus unsightly, as formed bending, became uneven etc.; Moreover, also there is the defect being not easy to use, as wiping desktop or be used as mop and use, need first to soak, use after making it to restore to the original state.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of making method simple and reliable, moisture content can be kept, easy to use, can shape be kept, be conducive to the attractive in appearance of product, and there is the making method of softening, to keep certain water ratio and antibacterial effect moisturizing sponge
The object of the invention is to have come by following technical solution, the making method of described moisturizing sponge, described sponge mainly adopts wood pulps and/or bamboo pulp to be that raw material is made by following several roads step, it mainly comprises immersion, squeezing, aging, yellow, make viscose material and foamable shaping, block sponge product is made through washing after stripping and slicing, described block sponge product is after washing, attract deposit through sufficient magnesium chloride solution, make the magnesium chloride solution containing 10-15% concentration in block sponge product, and after stopping magnesium chloride solution being attracted deposit, by extruding or compression method, the magnesium chloride solution of surplus is squeezed out, finally obtain the block sponge product containing 34-46% concentration magnesium chloride solution.
The temperature of the magnesium chloride solution that described block sponge product is attracted deposit is at 32-38 DEG C, and described washing comprises: with the salt that weak salt rinses strong salt wash, in and salt pickling and carry out bleaching washing by SYNTHETIC OPTICAL WHITNER; Described block sponge product to be attracted deposit district through soaking into or spray district by solution leaching duty or fully to attract deposit magnesium chloride solution after spraying at feeding solution.
It is simple and reliable that the present invention has making method, can keep moisture content, easy to use, can keep shape, is conducive to the attractive in appearance of product, and have softening, keep the features such as certain water ratio and antibacterial effect.
Embodiment
The present invention will be described in detail below: the making method of a kind of moisturizing sponge of the present invention, described sponge mainly adopts wood pulps and/or bamboo pulp to be that raw material is made by following several roads step, it mainly comprises immersion, squeezing, aging, yellow, make viscose material and foamable shaping, block sponge product is made through washing after stripping and slicing, described block sponge product is after washing, attract deposit through sufficient magnesium chloride solution, make the magnesium chloride solution containing 10-15% concentration in block sponge product, and after stopping magnesium chloride solution being attracted deposit, by extruding or compression method, the magnesium chloride solution of surplus is squeezed out, finally obtain the block sponge product containing 34-46% concentration magnesium chloride solution.
The preferred embodiment of the invention is: the temperature of the magnesium chloride solution that described block sponge product is attracted deposit is at 32-38 DEG C, and described washing comprises: with the salt that weak salt rinses strong salt wash, in and salt pickling and carry out bleaching washing by SYNTHETIC OPTICAL WHITNER; Described block sponge product to be attracted deposit district through soaking into or spray district by solution leaching duty or fully to attract deposit magnesium chloride solution after spraying at feeding solution.
The present invention is mainly relative to the sponge do not processed, enable after treatment to retain long period moisture content, described sponge is 1*1*0.4M, magnesium chloride solution is fully attracted deposit in the sponge of bulk, then after extruding or compression reduce amount of solution, improve the concentration of solution, due to the material that magnesium chloride is a kind of easy absorption moisture, through the process of attracting deposit of magnesium chloride solution, be conducive to block sponge product and contain finite concentration magnesium chloride solution, make wood pulp sponge keep moisture, play conformal effect.
