Method for preparing novel environment-friendly wallpaper based on high-filling synthetic paper

Abstract

The invention relates to a method for preparing a piece of novel environment-friendly wallpaper by a high-filling synthetic paper. The high-filling composite paper (also known as a replaceable plant fiber paper) is used as a base material, a coating material is coated on the base material to form a transparent coating, the coating material contains a water emulsion, a nano antibacterial, a pore-foaming agent, a flame retardant filler, an ink absorbing agent and the like, and a novel environment-friendly wallpaper with the waterproof, ventilating, mildewproof and flame retardant performances is manufactured by rotary screen, flat screen and gravure printing methods. Compared with the PVC (polyvinyl chloride) wallpaper, the novel environment-friendly wallpaper has the advantage that the coating and the printing are carried out at low temperature, the temperature is lower than 100 DEG C, and the temperature of the PVC wallpaper reaches to 220 DEG C during foaming and drying, so the energy-saving effect is favorably realized. Compared with the existing wallpaper, the novel environment-friendly wallpaper has the advantage that heavy metals, formaldehyde, plasticizers, VOC (volatile organic compounds) and the PVC are not contained, so the environment-friendly, ecological and health effects are realized.

Description

technical field [0001] The present invention relates to decorative wallpaper technology, in particular to a high-filling synthetic paper-based new environment-friendly wallpaper with waterproof, air-permeable, mildew-proof and flame-retardant properties after coating treatment and its preparation. method. Background technique [0002] Wallpaper (also known as wallpaper) is an indoor wall decoration material that is characterized by the combination of color and pattern design through the use of materials, equipment and craftsmanship, and is infinitely rich in expressiveness. It can conveniently meet the aesthetic requirements of diverse personalities and fashion needs. It is the most popular indoor wall decoration material at home and abroad. Wallpaper, like other decorative materials, is constantly developing and changing with the development of world economy and culture. The use of wallpaper in different periods is a reflection of the comprehensive factors of local econom...

With the continuous improvement of social environmental protection and safety requirements, it has become an inevitable trend to speed up the elimination of toxic plasticizers (including plasticizers that may have potential side effects) and the development and promotion of new non-toxic plasticizers. Therefore, the use of high-priced non-toxic plasticizers Plasticizer is one of the main issues facing PVC wallpaper; in addition, since polyvinyl chloride resin contains chlorine, when it is burned by fire, it will produce dioxins (dioxin), which are classified as carcinogens and substances that induce endocrine system disorders. , It also produces strong corrosive gas hydrogen chloride gas when burning, and is highly toxic, which is a harmful substance that is fatal to the human body

[0003]There are many kinds of wallpapers. From the surface material, they can be divided into ordinary rubber wallpapers, foam rubber wallpapers, paper wallpapers, knitted wallpapers, and metal wallpapers. , glass fiber wallpaper, and natural fiber wallpaper with jute as the finish, etc., in order to enhance air permeability, most of them use wood pulp fiber paper as the bottom paper. Once PVC paste is applied, it will lose air permeability. In addition, wood pulp paper does not Water resistant, not resistant to various microorganisms, prone to mildew, and easy to be eaten by moths, once the wall is wet, it will cause hollowing; in recent years, wallpapers using non-woven paper as the base material have been welcomed by people, using wood fiber and Synthetic fiber is made by wet process, but it is not flame retardant. Due to its porous characteristics, special surface treatment is required when making wallpaper to prevent ink from entering the fiber and affecting the printing effect

[0004]The flame retardancy of wallpaper is a must for wallpaper in public places, such as hotels, entertainment venues, airports, shopping malls, schools, kindergartens, hospitals, supermarkets and high-rise building decoration. Requirements, if most of the current wallpapers do not add flame retardants, they will not meet the requirements, which limits their use in these places. Therefore, the flame retardancy of most wallpapers is achieved by adding flame retardants. Aromatic phosphate flame retardants or ammonium polyphosphate flame retardants are added to a certain layer of polymer substrates of the wallpaper base material and combined with pentaerythritol compounds to achieve the purpose of flame retardancy, but the amount added is large, and the composition of the included 100 parts by weight of the basic resin of the layer, which is contained in an amount of 10-30 parts by weight, if the amount is less than 10 parts by weight, sufficient flame retardancy cannot be obtained, and if it exceeds 30 parts by weight, the composition containing a flame retardant The mechanical and physical properties of the layer drop

[0005] Therefore, some of the above-mentioned wallpapers contain polyvinyl chloride and toxic plasticizers that affect the living environment; The hollowing caused by the humid climate affects the decorative effect and is easy to breed bacteria; some wallpapers do not meet the requirements of flame retardancy and cannot be used on a large scale in public places and high-rise buildings. According to the defects of the above-mentioned wallpapers, it is necessary to develop new types of wallpaper Environmental protection wallpaper
