Decorative material with negative oxygen ion releasing environmentally-friendly and health-care functions and preparation method of decorative board therefrom

Abstract

The invention belongs to the field of building interior wall decorating materials, and particularly relates to a light-weight, gas-permeable and humidity-regulating composite material for an interiorwall, which is compounded by virtue of unique microporous properties of a diatom material matrix, is healthy and environmentally-friendly, has excellent performance in regulating the humidity of an indoor space (good moisture absorption and moisture release), has high gas permeability, can release negative ions, and have a health-care function, and a preparation method thereof. A decorative material with the negative oxygen ion releasing environmentally-friendly and health-care functions and a decorative board therefrom can be directly cut by using a wallpaper knife, can be directly nailed, can be directly processed by using a woodworking tool plane, can directly replace a sandwich panel, a wood board, a plywood and a simulated wood board in subsequent processing, and can be directly usedfor furniture manufacturing, cabinet combination manufacturing and the like; many problems such as roll stickiness, cracking and low qualification rate of a finished product due to strong adsorption force between diatomite and bentonite in the moulding process of the board are solved.

Description

technical field [0001] The invention belongs to the field of decoration and decoration materials for interior walls of buildings, and specifically relates to a kind of health and environmental protection compounded by using the unique microporous characteristics of diatom material matrix, which has excellent performance of adjusting indoor space humidity (good hygroscopicity and hygroscopicity), high air permeability, A decorative material with the function of releasing negative oxygen ions for environmental protection and health preservation and a preparation method for a decorative plate thereof. Background technique [0002] The main component of diatomite is silicic acid, which has the characteristics of superfiber and porosity. When the indoor humidity rises, the ultra-fine pores of diatomite can automatically absorb the moisture in the air and store it to avoid indoor pollution. The environment is moldy and deteriorated. If the moisture in the indoor air decreases and...

Problems solved by technology

In terms of humidity control materials, Japan has obtained a number of patents in recent years, mainly adding commonly used special silica gel, montmorillonite, inorganic salts, organic polymer materials and other humidity control materials into other materials to play the function of humidity control For example, the "healthy building materials" developed by Japan's INAX company can regulate indoor humidity; Hanada Kozo adds carbonized particles to binders, heats and presses them into carbonized humidity-controlling materials, etc., but these products have more or less disadvantages , For example, there is a serious hysteresis phenomenon in the moisture analysis of silica gel; the moisture capacity of montmorillonite is small; Slow speed; some new humidity control materials have complicated manufacturing process and high production cost

Chinese patent application 200610099093.3 discloses a moisture-regulating material for textiles and walls, which consists of a biocatalyst, 2-5nm porous mineral materials (sepiolite, diatomaceous earth, attapulgite, etc.) and superabsorbent resin , the humidity control range is 35-75% relative humidity. This humidity control material has a large moisture absorption capacity and good water retention, but at the same time, it also has the defects of small moisture release and slow moisture release speed. There is no case of direct use in large plates.

[0010] The technical solutions disclosed in the patent literature about diatomite and gypsum-based decorative building materials are: CN201502152U, CN201486076, and their common feature is that a single gypsum-based decorative plate is used as the base layer, and diatom mud is used as the finishing layer, that is, its diatom The soil wall material and the gypsum-based decorative board are formed by coating. There are limitations in product models, specifications, and patterns. The two are not integrated in technology. In terms of technology, there is secondary molding and long molding cycle due to the coating layer. At the same time, due to the potential of the interface layer Swelling and dissolution, low product performance and weather resistance

[0011] Using diatomite, especially grade C and D diatomite in Shangdu, Inner Mongolia, using composite technology to prepare decorative materials with environmental protection and health care functions and the preparation method of decorative panels has not been reported in the literature.
