Abstract

The invention relates to the technical field of building material preparation, in particular to a preparation method of silver-loaded palygorskite heat-resistant liquid wallpaper. According to the preparation method of the silver-loaded palygorskite heat-resistant liquid wallpaper, the silver-loaded palygorskite heat-resistant liquid wallpaper is prepared by taking modified epoxy resin as a matrix, taking a modified self-made nano-silicon dioxide powder, self-made silver-loaded palygorskite and modified aluminium hydroxide as fillers, and taking simethicone, gelatin and the like as auxiliary materials; firstly, the epoxy resin is modified by utilizing a silane coupling agent and diphenyl silanediol; the nano-silicon dioxide powder is subjected to surface modification through a dispersant,a coupling agent and an acidic solution, so that the antibacterial property of the wallpaper is improved; under a high-temperature condition, aluminium hydroxide is modified through a titanate coupling agent, so that the compatibility of the aluminium hydroxide and other filler is improved, the modified aluminium hydroxide is decomposed into aluminium oxide at a high temperature, and the aluminiumoxide can improve the chemical stability and the mechanical strength of glass, reduce a thermal expansion coefficient of the glass and remarkably improve the heat resistance of the liquid wallpaper,and has a wide application prospect.

Description

Technical field [0001] The invention relates to the technical field of building materials preparation, in particular to a method for preparing silver-loaded palygorskite heat-resistant liquid wallpaper. Background technique [0002] Liquid wallpaper is a new type of art paint, also known as wallpaper paint and wall art paint. It is an environmentally friendly water-based paint that combines the characteristics of wallpaper and latex paint. Through various special tools and techniques with different coloring techniques, the wall can produce various textures and artistic effects of light and dark transition. [0003] The liquid wallpaper is refined with high molecular polymer, imported pearlescent pigments and a variety of supporting additives. It is non-toxic, odorless, environmentally friendly, has strong water resistance, acid and alkali resistance, does not fade, does not peel, and does not crack. Make sure to use it for more than fifteen years. Liquid wallpaper is called green...
