Exterior wall putty powder prepared based on oil paint waste residues and preparation method thereof

Abstract

The invention discloses an exterior wall putty powder prepared based on paint waste residue and a preparation method thereof. The exterior wall putty powder comprises the following components in parts by weight: 10.51 parts of waste paint residue particles, 3.018 parts of cement, and 0.751 parts of plastic powder , 0.757 parts of anti-crack cellulose. The preparation method includes freezing and crushing paint waste residues; magnetic separation, removing impurities, crushing, adding cement, plastic powder and anti-cracking cellulose, and fully mixing to obtain finished exterior wall putty powder. The present invention can fully utilize the effective components in the paint waste residue, and the prepared exterior wall putty powder has high bonding strength, excellent water resistance and alkali resistance.

Description

technical field [0001] The invention belongs to the technical field of building base material production, and more specifically relates to an exterior wall putty powder prepared based on paint waste residue and a preparation method thereof. Background technique [0002] The exterior wall putty powder is made of inorganic gelling material as the base material, and finely processed with bonding materials and other additives. Its outstanding features are high bonding strength, water resistance, alkali resistance and good construction performance. The exterior wall putty powder can be used as a leveling material on the surface of outdoor buildings once and for all. The use of exterior wall putty powder with high bonding strength can effectively avoid cracking, foaming, pulverization and shedding on the surface of the exterior wall of the building.

Problems solved by technology

[0003] Paint is a common building base material in life and production. Generally, the paint in the decoration budget will always be calculated a little more to prevent insufficient purchase at one time and color difference in the second application. This determines that there will always be excess paint in the common use of paint Waste, most of these paint wastes are dry and hardened, and have not been used effectively, and many components in paint waste are the main components of exterior wall putty powder, and there is a certain space between them
