Process for producing building materials from raw paint sludge

Abstract

A process for producing building materials, such as asphalt, cement, concrete, mortar, or plaster board from liquid paint sludge containing water and paint solids produced from overspray in commercial paint booth operations. The preferred embodiment comprises adding the liquid paint sludge as the hydrating agent directly to the building material mix.

Description

technical field [0001] The present invention relates generally to a method of making building materials from paint waste, and more particularly to a method of using untreated paint waste from painting bench operations in the preparation of building materials such as asphalt, cement, concrete, mortar, and plaster Methods. Background technique [0002] Disposing of paint residue from large factory painting operations is time-consuming and laborious. When painting something like a car in a paint booth, the excess paint is picked up by a water curtain or stream of water under the worktop grill. This recycling is called paint residue. Disposal of paint residue is a complex issue faced by painters. Treatment technologies available today are generally based on methods of incineration, chemical and physical treatment and solidification. The end products of these treatment technologies are generally used in landfills. However, the use of paint residues in landfills has limitatio...

AI Technical Summary

Problems solved by technology

[0004] Disposal of paint residue is costly and time consuming, so there is a need for a simple and effective way to utilize all the paint residue generated during the painting process

[0005] There is no reference to the direct use of liquid paint residue as a component of concrete or cement-like building materials
