Abstract

The invention provides a matte interior wall latex paint, the total weight of which is 100%, and the matte interior wall latex paint comprises the following components by weight: 25-40% of a water-based self-extinction resin; 2-4% of a coalescing agent; 0.3-1% of a mildew inhibitor; 0.4-0.6% of rheological additive; 15-25% of pigment; 0.5-10% of an auxiliary agent; and 20-40% of water. The PVC content of the obtained matte interior wall latex paint is lower than 30%, the gloss of a paint film is lower than 3 at 20 degrees, 60 degrees and 85 degrees after the paint film is dried, the water permeability reaches 0.1 cm, and the matte interior wall latex paint has excellent alkali resistance, acid resistance, pollution resistance and doodling resistance. The wall latex paint can pass through the performance of superior products in GB / T9756-2018 synthetic resin emulsion interior wall paint, all the performance of JG / T210-2017 primer for building interior and exterior walls and the performance of class A in GB / T23999-2009 water-based wood paint for indoor decoration. Thewall latex paint can be widely applied.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to a matte interior wall latex paint and a preparation method thereof. Background technique [0002] Interior wall latex paint is a kind of coating with polymer emulsion as film former, and it is a kind of water-based coating formulated with synthetic resin emulsion as base material by adding pigments, fillers and various additives. Interior wall latex paint is one of the main decorative materials for interior walls and ceilings. It is characterized by good decorative effects, convenient construction, little environmental pollution, low cost, and extremely wide application. [0003] At present, the commonly used latex paints for interior walls include matte paint, glossy paint, silky paint, glossy paint, and high-gloss paint. Among them, matte interior wall latex paint generally uses bright emulsion as raw material, and then adds a large amount of matting materials such as pigme...
