Abstract

The invention discloses a smell-clearing waterborne colorful paint composition and a preparation method thereof. The composition comprises the following components in percentage by weight: 10-15% of water, 0.1-0.2% of AMP-95, 1.0-1.5% of a film-forming additive, 20-30% of a soap-free polymerized elastic emulsion, 0.1-0.3% of a preservative and 53-68% of color particles. When the smell-clearing waterborne colorful paint composition is prepared, a colloidal solution and base paint are firstly prepared; color paste is added into the base paint to prepare color-mixing base paint, the color-mixing base paint is further added into the colloidal solution and dispersion and granulation are performed to prepare the color particles; and the water, the AMP-95, the film-forming additive, the soap-free polymerized elastic emulsion, the preservative and the color particles are uniformly mixed to prepare the smell-clearing waterborne colorful paint composition. The smell-clearing waterborne colorful paint composition disclosed by the invention mainly comprises a non-toxic and odorless finely classified filler, the emulsion and other additives, and the limit of harmful substances is in line with the requirements of GB 24408-2009 'Limit of harmful substances in exterior wall coatings for buildings'.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials, and in particular relates to an odor-cleaning water-based colorful paint composition and a preparation method thereof. Background technique [0002] Water-based colorful paint is a kind of paint that can realistically restore the decorative effect of marble and granite; because of its light weight, it is especially suitable for indoor and outdoor decoration of various buildings, and it is an economical substitute for high-grade stone. The existing water-based colorful paint is basically a water-in-water model, and its components are divided into a dispersed phase and a continuous phase. The combination of vinyl alcohol and cellulose is made after gelling with alum. This kind of base paint loses its toughness after gelling, and the color particles made are very dull, difficult to construct, and easy to bloom; The polymer structure has poor weather resistance, and the colorful ...
