Abstract
The invention relates to a preparation method of flexible rock mud and environment-friendly art paint. The preparation method of the environment-friendly artistic paint comprises the steps of scraping a layer of flexible rock mud on a base material as a putty layer; and after the flexible rock mud is polished to be smooth, a layer of flexible rock mud is scraped in batch and used as formal surface coating, and the surface is cleaned after the flexible rock mud is dried.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to multipurpose flexible rock mud and a preparation method thereof.
Background
The putty is a decorative material for leveling the surface of a wall body, is thick paste paint and is an essential product before painting. The putty is applied on the primer or directly applied on the object to remove the defects of high and low unevenness on the surface of the object to be coated. When the wall is constructed, because the wall is uneven, the primer is generally required to be brushed twice, after the flatness and the strength are enough, putty, namely a putty layer, is scraped twice, the first putty layer is dried, is polished by abrasive paper to be smooth, a second putty layer is scraped after necessary repair is carried out, and finally, formal wall paint is brushed on the surface of the second putty layer. This process is relatively cumbersome.
Patent application CN107974124A discloses an exterior wall putty powder and a preparation method thereof, wherein the exterior wall putty powder comprises: 180-250 parts of calcium carbonate powder, 60-100 parts of white cement, 2-8 parts of hydroxyethyl cellulose, 8-12 parts of nano alumina, 8-12 parts of nano titanium dioxide, 10-15 parts of polymethyl methacrylate, 5-8 parts of tungsten zirconate and 5-8 parts of EVA plastic raw material. The exterior wall putty powder has good anti-cracking effect, weather resistance, water resistance and other properties, belongs to conventional acrylate putty, and is not environment-friendly, wherein the exterior wall putty powder contains acrylic acid or acrylic ester, is generally an oily material, and relates to various organic additives to form stable fluid.
Patent application CN105619549A discloses a process for the repair of a substrate, comprising the following operations: (1) and (3) large repairing: mixing marble glue and a curing agent mixture, and coating the mixture on the surface of a substrate plate; (2) fine repairing: mixing putty powder, water and white latex, standing to obtain mixed putty, and smearing on the surface of a substrate plate for 2 times; (3) sanding: drying the putty on the surface of the substrate board subjected to the fine repair in the step (3) for 12-48 h, and then polishing once, so that the putty fills and levels holes and gaps, burrs, depressions and the like caused by explosion cracking on the substrate board, then coating a layer of putty A, wherein the thickness of the coated putty A is 0.3mm, and polishing once again after the putty A is dried; (4) and (3) drying: and drying the substrate obtained after sanding until the water content of the wood board is less than or equal to 10%. The substrate produced by the method has flat and smooth surface, but the construction process is too complicated and the flow is long.
