Abstract

The invention relates to putty powder, in particular to functional diatomite putty powder and a preparation method thereof, wherein the putty powder includes in percent by weight: 10-50% of high-temperature activated diatomite, 5-30% of an inorganic binder, 30-70% of an inorganic filler, 0.01-2% of a functional aid, 0.1-5% of an inorganic pigment, 0.5-5% of an organic binder, and 0.5-5% of an organic aid. The functional diatomite putty powder meets the related standard requirements of putty powder and diatomite, and has qualified constructability and functionality, namely having standard-meeting properties such as humidity regulation, formaldehyde clarifying performance, long duration of formaldehyde purifying performance, mold-proof performance, and mold durability.

Description

technical field [0001] The invention relates to putty powder, in particular to a functional diatom mud putty powder and a preparation method thereof. Background technique [0002] Putty powder is a base surface treatment material that is applied to the interior wall of a building before the decoration project for the main purpose of leveling, including general type, flexible type and water resistance. Putty powder has a single function, but in recent years, in order to increase the functionality of putty powder, a variety of functional raw materials have been added to putty powder, and diatomaceous earth is one of them. There have been many reports on adding diatomaceous earth to putty powder. Chinese patent CN101942237A reports that the functional putty powder that can increase negative ions contains 5-15% diatomite; CN104403399A reports that the interior wall putty with moisture-regulating and moisture-proof functions can contain 10-35 parts of diatomite as an auxiliary h...
