Anti-sedimentation agent added into building coating and preparation technology

Abstract

The invention discloses an anti-sedimentation agent added into building coating and a preparation technology. According to the anti-sedimentation agent added into the building coating and the preparation technology, the anti-sedimentation agent is prepared from the following raw materials in parts by mass: 20 to 25 parts of de-ionized water, 0.4 to 0.6 part of a dispersant, 4 to 6 parts of an anti-sedimentation agent, 0.7 to 1.1 parts of a preservative, 0.3 to 0.5 part of a pH (Potential of Hydrogen) stabilizing agent, 0.2 to 0.5 part of a de-foaming agent, 14 to 20 parts of pigment and filler, 65 to 75 parts of waterborne hydroxyl dispersion, 45 to 55 parts of resin, 2 to 4 parts of a curing agent, 45 to 55 parts of hydrophilic modified polyisocyanate, 55 to 65 parts of methyltrimethoxysilane, 18 to 24 parts of silica sol and 75 to 85 parts of elastic emulsion. The coating disclosed by the invention has the beneficial effects that the coating has the advantages of environment protection, no ignition under fire, no expansion, no emission of smoke and long quality guarantee period at room temperature; the building coating has stable components and a good adhesion force and is convenient to construct; the anti-sedimentation agent is directly added into the coating through a special processing manner, so that the coating has a better wetting and dispersion function; and the leveling property and the anti-sedimentation effect are more obvious.

Description

technical field [0001] The invention relates to the technical field of new architectural materials, in particular to an anti-sedimentation agent added to architectural coatings and a preparation process. Background technique [0002] Architectural coatings can present patterns of various colors at the same time through sequential spraying, making various colors interlaced and having a decorative effect similar to natural granite or marble. It is mainly used for interior and exterior wall decoration of high-end buildings, and the decoration can be diversified. more humane. [0003] Application number CN201711408404.4 is a two-component water-based multi-color paint coating. The patent mentions a two-component water-based multi-color paint coating. It is mentioned that the effect of anti-settling agent on wetting dispersion and leveling is not very obvious , The anti-settling effect of the product is poor, which will eventually affect the stability of architectural coatings...
