Abstract

Disclosed are a compressed sponge product and a manufacturing method. The compressed sponge product comprises a block-shaped sponge body, wood pulp and/or bamboo pulp serves as raw materials to make the block-shaped sponge body by the aid of processes such as soaking, pressing, yellowing, gluing and foam forming, the water content of the block-shaped sponge body is lower than 3%, the block-shaped sponge body is placed into a die cavity of a hot press and pressed into a square sponge product, the thickness of the square sponge product ranges from 5mm to 15mm, the square sponge product is a rectangular sponge product, the outside of the rectangular sponge product wraps a sealed packaging layer in a vacuum manner, and regular or irregular shallow strip-type concave and convex groove grains are formed on the upper surface and the lower surface of the square sponge product. The manufacturing method includes the steps: washing the block-shaped sponge body; at least washing the block-shaped sponge body by the aid of weak salt, neutralization acid and bleaching agents after the block-shaped sponge body is cut in the form forming process; placing the block-shaped sponge body into the die cavity of the hot press after the block-shaped sponge body is dried at the lower temperature, and pressing the dried block-shaped sponge body into a thin sponge product.

Description

A kind of compressed sponge goods and preparation method

Technical field

What the present invention relates to is the degradable compressed sponge goods made of a kind of main employing lignose and preparation method, belongs to sponge product and preparing technical field.

Background technology

Sponge is a kind of porous material, has good water imbibition, can be used in clean article.The sponge that people commonly use comprises: with wood cellulose fibers or two kinds of sponge products making with foamed plastic polymer.Because the sponge cost made with foamed plastic polymer 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 Long-Time Service, apt to deteriorate, hardening, reduce service 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 lignose 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 cost of material 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 ambient influnence, can regenerate and not have an environmental pollution, long service life, thus general high-grade life appliance still more selects this sponge products.

At Chinese patent ZL201010275805,9 disclose a kind of bamboo pulp sponge product, it is mainly made by operations such as immersion, squeezing, yellow, viscose glue, foamings, due to the foamed products that sponge product is a kind of bulk, in puffy, volume is large, lightweight, easy breed bacteria etc. in time one long cavernous body, therefore use storage all inconvenient.

Summary of the invention

The object of the invention is to the deficiency overcoming prior art existence, and it is simple to provide a kind of structure to form, easy to make, be widely used, be convenient to promote, and storage convenient transportation, reduce costs, the compressed sponge goods of degradable environment-friendly type and preparation method.

The object of the invention is to have come by following technical solution, described a kind of compressed sponge goods, it comprises one and uses wood pulps and/or bamboo pulp as raw material, by the operations such as immersion, squeezing, yellow, viscose glue, foaming make moisture content lower than less than 3% block cavernous body, described block cavernous body is placed in the die cavity of a hot press, is pressed into the square sponge goods of thickness at 5-15mm.

Described square sponge goods are rectangle sponge product, and the outside vacuum packet of this rectangle sponge product is covered with and packs layer, and the upper and lower surface of described square sponge goods is formed with rule or irregular shallow bar shaped tongue and groove line.

Described preparation method comprises the washing process of block cavernous body, at foaming and after cutting into block cavernous body, at least wash through weak salt, in and pickling and wash three process with the bleaching of bleaching agent, then by after low temperature drying, be placed in the die cavity of a hot press, lower than under 80 DEG C of temperature, 10-15Mpa pressure, through the hot pressing of at least 5 minutes, be pressed into described slim sponge product.

Described slim sponge product, through a vacuum film packing machine, is coated with one deck and packs layer outside it, and the described layer that packs is the wrapping paper that a plastic sheeting or painting are shaped with thin layer.

It is simple, easy to make that the present invention has structure composition, is widely used, and is convenient to promote, and storage convenient transportation, reduce costs, the features such as degradable environment-friendly type.

Accompanying drawing explanation

Fig. 1 is structure of the present invention composition schematic perspective view.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail: shown in Fig. 1, a kind of compressed sponge goods of the present invention, it comprises one and uses wood pulps and/or bamboo pulp as raw material, by the operations such as immersion, squeezing, yellow, viscose glue, foaming make moisture content lower than less than 3% block cavernous body 1, described block cavernous body is placed in the die cavity of a hot press, is pressed into the square sponge goods 1 of thickness at 5-15mm.

Shown in figure, described square sponge goods are rectangle sponge product 1, and the outside vacuum packet of this rectangle sponge product is covered with and packs layer 2, and the upper and lower surface of described square sponge goods is formed with rule or irregular shallow bar shaped tongue and groove line 3.

A kind of preparation method of compressed sponge goods described above, described preparation method comprises the washing process of block cavernous body, at foaming and after cutting into block cavernous body, at least wash through weak salt, in and pickling and wash three process with the bleaching of bleaching agent, then by after low temperature drying, be placed in the die cavity of a hot press, lower than under 80 DEG C of temperature, 10-15Mpa pressure, through the hot pressing of at least 5 minutes, be pressed into described slim sponge product.

Slim sponge product of the present invention, through a vacuum film packing machine, is coated with one deck and packs layer outside it, and the described layer that packs is the wrapping paper that a plastic sheeting or painting are shaped with thin layer.
