Problems solved by technology

[0003] The anti-corrosion materials used in the existing putty mostly include volatile harmful substances such as formaldehyde, benzene, ammonia, etc., which are harmful to people's health
[0004] In addition, the existing putty tends to have high hardness and poor crack resistance, and when the crack resistance is good, the hardness is difficult to meet the requirements; and when using the existing putty for construction, it is necessary to first coat a layer of interface agent on the bottom layer, and the construction is complicated

Abstract

The invention discloses putty powder and belongs to the field of building decoration materials. The putty powder is prepared from 400-600 parts of ground limestone, 50-200 parts of hydroxyapatite, 100-200 parts of diatom powder, 30-100 parts of asbestos fiber, 50-100 parts of plastic powder, 10-30 parts of starch ester, 10-80 parts of a bonding agent, 5-20 parts of arrow grass, 10-50 parts of homalomena occulta, 2-8 parts of Ligustrum sinense, 10-30 parts of European pannum, 5-20 parts of tarragon and 2-8 parts of pennycress. Due to the hydroxyapatite, the crack resistance of the putty powder is improved, and meanwhile the hardness and glossiness of putty are improved; due to the fact that the diatom powder and asbestos fiber are porous materials, noise reduction can be achieved, and harmful gas in air can be absorbed; the plastic powder and the ground limestone are used as padding of the putty powder, so that the glossiness is good, and the putty is easier to form, good in forming performance and not prone to cracking.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a putty powder. Background technique [0002] Putty is a decorative material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. It can fill the partially sunken working surface, or scrape off the entire surface. It is usually applied to the surface of the primer layer after the primer layer is completely dry. It is required to have good adhesion and no cracks during the baking process. [0003] Most of the anticorrosion materials used in the existing putty include formaldehyde, benzene, ammonia and other volatile harmful substances, which are harmful to people's health. [0004] In addition, the existing putty tends to have high hardness and poor crack resistance, and when the crac...
