Abstract

The invention discloses an environment-friendly thermal-insulation heat-preservation latex paint and a preparation method thereof, wherein the environment-friendly thermal-insulation heat-preservation latex paint is prepared from the following components in parts by weight: 2.5-6.2 parts of aluminum silicate, 1.2-2.5 parts of a quartz powder, 10-15 parts of titanium dioxide, 18-25 parts of white latex, 2.5-4.2 parts of methyl octyl aldehyde, 1.3-2.6 parts of dioctyl sodium sulfosuccinate, 1-4 parts of lignin, 2-3 parts of calcium fluoride, 2.5-4.5 parts of a ceramic micro-powder and 3.5-4.7 parts of polyethylene glycol. Compared with conventional latex paints, the product has the advantages of no formaldehyde, extremely low contents of other VOCs, environmental friendliness and excellent thermal-insulation heat-preservation performance, and is an ideal exterior wall decorative material.

Description

technical field [0001] The invention belongs to the field of architectural coatings, and in particular relates to an environmentally friendly heat-insulating latex paint and a preparation method thereof. Background technique [0002] Coating refers to a general term for a class of liquid or solid materials that are applied to the surface of an object to form a solid coating film and have protective, decorative or special properties. Most of the early paints used vegetable oil as the main raw material, so they were called "paints". The scope of coatings is very wide, and varnishes, wood varnishes, insulating varnishes, automotive paints, etc. all belong to the scope of coatings. Latex paint is a common name for latex paint, and it is currently a popular architectural paint for interior and exterior walls. With the rise of the home decoration trend, architectural coatings, as a growing branch of the coating family, have an increasingly close relationship with consumers. [...
