Problems solved by technology

[0003] The most common coating slurry currently on the market is mainly composed of PVC resin and fillers. Although this coating material has the advantages of being beautiful, durable and waterproof, it has poor air permeability and contains organic solvents, which will pollute the indoor air after long-term use. , with the improvement of people's awareness of environmental protection, the environmental protection requirements for wallpaper are getting higher and higher, which undoubtedly requires the use of new coating materials to replace PVC resin
In recent years, a number of environmentally friendly water-based resin coating materials have emerged on the market. Although these materials do not contain volatile organic solvents, they have excellent performance in terms of air permeability, plasticizing temperature, additional functionality, and adhesion to substrates. There are still deficiencies

Embodiment Construction

[0016] The wallpaper of this embodiment is made of a non-woven fabric substrate and a coating slurry coated on the surface of the substrate after drying, plasticizing, and embossing, wherein the coating slurry is made of the following raw materials in parts by weight: composite Water-based acrylic resin emulsion 80, volcanic rock powder 2, graphene 0.01, polylactic acid slice 8, vinyl bis stearic acid amide 0.1, silane coupling agent kh5500.1.

[0017] The coating slurry preparation method is:

[0018] (1) Preparation of polylactic acid porous fiber from volcanic rock: Firstly, polylactic acid chips, volcanic rock micropowder, graphene, vinyl distearic acid amide, and silane coupling agent kh550 were mixed evenly, and then melt-spun to make a length of 80 μm. Porous short fibers with a diameter of 30 μm;

[0019] (2) Put the polylactic acid porous fiber of volcanic rock into the composite water-based acrylic resin emulsion, stir and mix for 30 minutes, then add other remainin...

Abstract

The invention discloses wallpaper containing a volcanic rock-polylactic acid porous fiber modified acrylic resin emulsion coating. A cellulose acetate-copolymerized modified waterborne acrylic resin emulsion is adopted as a resin adhesive in coating slurry used for the wallpaper, and is stable in performance and free of toxic compounds slow in volatilization such as formaldehyde. The formed coating is smooth and elastic and has waterproof, antifouling and antibacterial functions and other functions. Compared with traditional PVC paste, plasticizing temperature of the coating is lower, and the coating is more energy-saving and environmental friendly. Graphene-doped volcanic rock-polylactic acid porous fibers have functions of high strength, heat preservation, thermal insulation, sound absorption, porosity, formaldehyde removing, and the like. Adsorbability with a substrate is improved. The service lifetime of the wallpaper is effectively prolonged. The wallpaper has a certain indoor air cleaning function.

Description

technical field [0001] The invention relates to the technical field of wallpaper, in particular to a wallpaper containing volcanic rock-polylactic acid porous fiber modified acrylic resin emulsion coating. Background technique [0002] Wallpaper, also known as wallpaper, is more and more widely used in home decoration because of its advantages of various colors, rich patterns, luxury style, safety and environmental protection, convenient construction, and affordable price. Most common wallpapers are based on pure paper, non-woven fabrics and other materials. The material is coated with resin slurry on its surface, and it is made through high-temperature plasticization, printing and embossing and other processes. [0003] The most common coating slurry currently on the market is mainly composed of PVC resin and fillers. Although this coating material has the advantages of being beautiful, durable and waterproof, it has poor air permeability and contains organic solvents, whic...
