Abstract

The invention relates to the technical field of latex paint, in particular to environment-friendly latex paint for decoration and a preparation method thereof. The environment-friendly latex paint fordecoration at least comprises the following raw materials in parts by weight: 100-300 parts of polymer emulsion, 80-180 parts of filler, 100-200 parts of water, 10-20 parts of pigment, 2-10 parts ofan antifoaming agent, 2-10 parts of a thickener, 2-10 parts of a leveling agent, 2-10 parts of a dispersing agent and 0-10 parts of other assistants. The latex paint is reasonable in compatibility, and the obtained latex paint is low in formaldehyde content and VOC content, environmentally friendly and high in safety. Tests prove that formaldehyde is not detected in the latex paint, the VOC content is lower than 5 g / L and far lower than the requirements of the national standard, and the latex paint is non-toxic and harmless in production, construction and use, and can effectively absorb harmful gas and purify air.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to an environment-friendly latex paint for decoration and a preparation method thereof. Background technique [0002] Latex paint is an indispensable paint material in the field of modern decoration, and latex paint for interior walls is a product of the field of modern interior decoration. Latex paint is a common name for latex paint. It was born in the middle and late seventies of the 20th century. It is a large class of thin-coated paint represented by acrylate copolymer emulsion. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy brushing, fast drying, and water-resistant paint film. [0003] Nowadays, with the continuous deepening of the concept of green environmen...
