Embodiment 1
[0032] A method for preparing an environment-friendly, temperature-adjustable wallpaper base material is characterized in that it is prepared according to the following steps by using the following raw materials and the ratio of parts by weight:
[0033] (1) Preparation of modified calcium carbonate powder: Weigh 100 parts of the pre-dried calcium carbonate powder through a 2000-mesh sieve, and then weigh 1 part of γ-methacryloxypropyl trimethoxy as the surface treatment agent Add base silane (KH570) into a high-speed mixer that can be heated up, heat up to 80°C and stir at high speed for 120 minutes to obtain modified calcium carbonate powder;
[0034] (2) Preparation of mixed pellets: 25 parts of purified and dried self-synthesized polyether ester copolymer (polyethylene terephthalate-co-polyethylene glycol copolymer, intrinsic viscosity 0.40dL / g The molecular weight of polyethylene glycol is 1000g / mol, and the proportion in the copolymer is 80%. It includes two traditional ...
