Description

Facing paper with formaldehyde purification function

Technical Field

The invention relates to the technical field of facing paper, in particular to facing paper with a formaldehyde purification function.

Background

In the past, the plate used for processing furniture needs to be painted after being processed and formed, so that on one hand, the processing and the use are complicated, and on the other hand, the paint contains harmful substances such as formaldehyde, benzene and the like, so that the health of a human body is influenced; along with the appearance of the veneer paper, the processing of the plate becomes relatively convenient, and the visual effects such as grain texture and the like are very good, so that the veneer paper is popular with consumers. The research of Chinese nano materials and nano structures obtains remarkable achievements, at present, the achievements of China in the field of nano materials science are higher than those of any country in the world, and the fact that China plays a very important role in the field of nano technology is fully proved. As the house can still generate harmful substances such as formaldehyde, benzene and the like after being decorated, the veneer paper on the market at present has various types and exquisite appearance, but does not have the purification effect, can not remove the harmful substances and is difficult to meet the requirements of consumers.

Disclosure of Invention

The invention aims to solve the problems and provide facing paper with a formaldehyde purifying function.

The invention realizes the purpose through the following technical scheme:

the facing paper with the formaldehyde purifying function comprises the following raw materials in percentage by weight: 70-85% of wood pulp, 5-10% of chemical fiber, 5-10% of auxiliary agent, 5-8% of adhesive, 1-5% of nano negative ion liquid and 1-5% of nano photocatalyst;

the wood pulp is softwood pulp;

the chemical fiber is one or more of polyamide 6 fiber, polyacrylonitrile fiber, polyester fiber, polypropylene fiber and polyvinyl formal fiber;

the auxiliary agent is polyacrylamide and polyamide epichlorohydrin resin, wherein the ratio of polyacrylamide to polyamide epichlorohydrin resin is 1: 1-1.5.

Preferably, the raw materials used are as follows by weight percentage: 70-80% of wood pulp, 5-8% of chemical fiber, 5-8% of auxiliary agent, 6-8% of adhesive, 1-3% of nano negative ion liquid and 1-3% of nano photocatalyst.

Has the advantages that: chinese nanomaterials and nanostructures achieved dramatic achievements. At present, the achievement of China in the field of nano materials is higher than that of any country in the world, and the invention fully proves that China plays a very important role in the field of nano technology.

The material adopted by the invention utilizes the characteristics of nanotechnology such as surface effect, small-size effect, macroscopic quantum tunnel effect and the like to generate a large amount of negative ions, hydroxyl radicals and active oxygen, and the negative ions, the hydroxyl radicals and the active oxygen are electrically neutralized and settled with indoor pollutants such as ammonia gas, formaldehyde and the like to remove gaseous pollutants.

Detailed Description

The technical scheme of the invention is further explained by combining the following embodiments:

example 1

A facing paper with formaldehyde purification function comprises 70% -85% of wood pulp, 5% -10% of chemical fiber, 5% -10% of auxiliary agent, 5% -8% of adhesive, 1% -5% of nano-anion liquid and 1% -5% of nano-photocatalyst;

the wood pulp is coniferous wood pulp, the coniferous wood has a tight structure, long and thin fibers, and the coniferous wood pulp is relatively pure, has few impurities, high folding resistance and good tensile strength.

The chemical fiber is one or more of polyamide 6 fiber, polyacrylonitrile fiber, polyester fiber, polypropylene fiber and polyvinyl formal fiber, and is mainly used for increasing the wear resistance and tensile strength of a finished product and has good toughness;

the auxiliary agent is polyacrylamide and polyamide epichlorohydrin resin, wherein the ratio of the polyacrylamide to the polyamide epichlorohydrin resin is 1:1-1.5, and the polyacrylamide is used for improving the retention rate of fillers, pigments and the like so as to reduce the loss of raw materials and the pollution to the environment; and secondly, the strength of the paper is improved, and the polyacrylamide is added into the paper stock, so that the retention rate of the fine fibers and the filler particles on the net can be improved, and the dehydration of the paper stock is accelerated. The action mechanism of the polyacrylamide is that the particles in the slurry are retained on the filter cloth by electric neutralization or bridging flocculation; the polyamide epichlorohydrin resin has cationic property, is easy to combine with fiber, and can make paper have good wet strength and make decorative paper soft.

The nanometer photocatalyst absorbs electrons escaping after sunlight has strong reducibility, and the holes have strong oxidizing property, and the electrons and the holes react with water vapor in the air to generate active oxygen and hydroxyl radicals, and the active oxygen and the hydroxyl radicals can oxidize and decompose most organic matters, pollutants, odor, bacteria and the like into harmless carbon dioxide and water.

The nanometer anion liquid can release a large amount of anions which have the effects of sterilizing and decomposing carcinogens such as formaldehyde, benzene and the like, and the decomposed products are nontoxic and tasteless carbon dioxide and water.

Example 2

The difference between the embodiment and the embodiment 1 is that the raw materials used in the embodiment are as follows by weight percentage: 70-80% of wood pulp, 5-8% of chemical fiber, 5-8% of auxiliary agent, 6-8% of adhesive, 1-3% of nano negative ion liquid and 1-3% of nano photocatalyst.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
