Abstract

The present invention discloses color-changing putty powder and a preparation method thereof, and relates to the technical field of building materials. The preparation method of the color-changing putty powder is as follows: raw material components of white cement, ash calcium powder, redispersible glue powder, talc powder, calcium carbonate, diatomaceous earth, barite powder, mica powder, silica,pottery clay and a binder are mixed; distilled water is added to the mixture; the mixture is placed in a reaction kettle; the mixture is continuously stirred at a rotation speed of 500-650 r / min for2-3 hours; a coloring agent is added to the mixture obtained in the first step; the mixture is stirred evenly at 80-100 DEG C; lignocellulose and a thixotropic lubricant are added to the mixture obtained in the second step to be stirred evenly; then an accelerator is then added; the mixture obtained in the third step is taken out to be put still; the put still mixture is subjected to forced air drying; and the dried mixture is crushed. By using the above technical solution, beneficial effects are as follows: the putty powder capable of changing color with temperatures and light rays is prepared; and the color-changing putty powder is good in water resistance and long in service life, can be used as the powdery putty, and reduces packaging and transportation costs.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a color-changing putty powder and a preparation method thereof. Background technique [0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before painting. The purpose of applying putty is to fill the pores of the construction surface and correct the curve of the construction surface Deviation, to lay a good foundation for obtaining a smooth and uniform paint surface, while the traditional putty powder often uses ash calcium powder as the base material, the calcification reaction mainly occurs on the outer surface of the putty powder layer, and there is still a large amount of unstable calcium oxide on the inner surface And strong calcium oxide, resulting in the existence of putty powder layer, the inner layer is soft, and the coating is prone to bubbles and cracks after ...
