Paint composite prepared from waste paint residues and preparation method thereof

Abstract

The invention discloses a paint composite prepared from waste paint residues and a preparation method thereof. The paint composite comprises, by weight, 80 parts of waste paint residue particles, 10 parts of titanium dioxide and 10 parts of methyl cellulose. The preparation method comprises the following steps: freezing the waste paint residues and carrying out crushing and magnetic separation; removing impurities and then carrying out crushing so as to obtain the waste paint residue particles with particle sizes of 250 to 300 meshes; adding titanium dioxide and methyl cellulose into the waste paint residue particles obtained in the previous step; and carrying out full mixing so as to obtain the finished paint composite. According to the invention, the active components in the waste paint residues can be made full use of; and the prepared paint composite can be used as a matching raw material for exterior wall putty powder or elastic putty powder, turns the waste into the valuable and overcomes secondary pollution caused by treatment of the waste paint residues.

Description

technical field [0001] The invention belongs to the technical field of building base material production, and more specifically relates to a paint composite material prepared based on paint waste residue and a preparation method thereof. Background technique [0002] 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 paint composite materials, and there is a certain usable space between the two. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to solve the deficiencies in the prior art, and provide a ...
