Abstract
The invention relates to a thick knife-coated sand-textured building paint. The thick knife-coated sand-textured building paint comprises a sand-textured building paint emulsion, hydroxyethyl cellulose, an organic amine neutralizer, an antifoaming agent, an anti-whitening conditioning agent, an antifreezing agent, a film-forming aid, a bactericide, a waterborne anti-cracking agent, a bulking agent, a thickening agent, natural colored sand and water. The thick knife-coated sand-textured building paint has a decorative function and a protective function, is adaptive to knife-coating in batches, does not produce paint mist during construction and is free of the phenomenon of splash of the paint; a paint film formed by the paint has excellent performance like alkali resistance and artificial weathering aging resistance; the preparation method is simple in process, poses no adverse influence to operators during production and is suitable for industrial production. After construction, the thick knife-coated sand-textured building paint can produce identical decorative effect as natural stone while cost is reduced; the thickness of the paint is obviously higher than common sand-textured building paint; and the paint looks thick and heavy just as natural stone.

Limits of harmful substances in sufficient HJ2537-2014 environmental labelling products technical requirements and GB24408-2009 exterior coatings for building,
It is a kind of environment-friendlywater-based water-based paint for meeting current generation demand.Commercially available sand textured building coating B5001-2, L601 and this
Thick matter blade coating sand textured building coating of the content of volatile organic compound (VOC) of bright comparative example apparently higher than the present invention.
Decoration functions and defencive function that the sand textured building coating in the invention has sand textured building coating are employed, product can
Criticize to scrape and do not produce in construction, work progress coating cloud, do not produce paint vehicle splashing, thus atmosphere pollution and solid waste will not be produced；
Product can thickness be applied to more than 6mm, surface drying time≤4h, initial dry cracking resistance pass through, diameter (50 ± 2) mm, weight
The spherical counterweight of 1000g ± 10g freely falls from height 500mm, at a distance of three positions of 50mm, detects by an unaided eye,
Coating surface flawless, peeling and substantially deformation；The coating paint film has the excellent property such as alkali resistance, artificial weathering ageing resistance
Can, and the thick matter blade coating sand textured building coating is non-dangerous article, to production, transport, is stored in a warehouse without strict fire protection requirement；
Operating personnel are had no adverse effects by the product preparation method process is simple of the present invention during production, are suitable to industrialization production；The present invention
Be obtained and the equal decorative effect of lithotome after product construction, but cost can decline 35～80%, and product thickness apparently higher than
Common sand textured building coating, shows the thick and heavy effect same with lithotome；Simultaneously product adhesive force is strong, and toolability is strong.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still can make various
Modification and conversion are without departing from the spirit and scope of the present invention.Therefore, specification is regarded in an illustrative, rather than a restrictive.
