Abstract

The invention discloses an environment-friendly wallpaper substrate capable of regulating temperature, which is prepared from the following raw materials in parts by weight: 15-25 parts of polyester ether copolymer, 75-85 parts of modified calcium carbonate powder, 0.075-0.5 part of heat stabilizer. The modified calcium carbonate powder is prepared from the following raw materials in parts by weight: 100 parts of calcium carbonate and 0.5-1 part of surface treating agent. The invention has the advantages of ingenious structure, simple links and low cost, and can well ensure the prepared wallpaper substrate to have strong temperature regulation capacity and high stability; and meanwhile, the polyethyleneglycol has hydrophilic groups, so that the moderate hydrophilicity on the prepared wallpaper substrate surface is beneficial to environment-friendly water-soluble emulsion coating and circular screen printing.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an environment-friendly, temperature-adjustable wallpaper base material and a preparation method thereof. Background technique [0002] Decorative wallpaper is the most widely used wall decoration material at home and abroad. There are many materials for making wallpaper, which can be roughly divided into four categories: paper, textiles, natural materials and plastics. Because the composition of the wallpaper is different, its impact is also different. Textile fragments in natural textile wallpapers, especially pure wool wallpapers, are allergens that can cause allergies in humans. Some chemical fiber textile wallpapers can release harmful substances such as formaldehyde, polluting indoor air. Plastic wallpaper (PVC base material) has developed very rapidly due to its advantages of beauty, low price, durability, easy cleaning, long life, and convenient construction. At p...
