Abstract

The invention discloses an environment-friendly interior wall formaldehyde removal styrene-acrylic emulsion as well as a preparation method and a coating thereof. The emulsion is prepared from the following components in parts by weight: 100 parts of deionized water, 30-35 parts of styrene, 40-45 parts of acrylate, 10-15 parts of methacrylate, 1.5-3 parts of alkyl acrylic acid, 1-5 parts of an acrylic acid functional monomer, 0.5-5 parts of an aldehyde removal functional monomer, 0.1-0.5 part of a functional crosslinking monomer, 1-5 parts of an emulsifier, 0.5-3 parts of an initiator, 0.05-1part of a buffer agent, 0.1-0.5 part of a residual monomer treatment initiator and 1-4 parts of a rapid aldehyde removal aid. The preparation method is simple in technological operation and good in controllability. The emulsion prepared through the preparation method is stable in particle size, good in performance and low in cost, integration of rapid formaldehyde removal and long-term formaldehyde removal of an interior wall coating system is achieved, and the excellent formaldehyde removal effect is achieved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly paint and its preparation, in particular to an environment-friendly interior wall aldehyde-removing styrene-acrylic emulsion, a preparation method thereof and a paint. Background technique [0002] With the vigorous development of the domestic real estate industry, decoration is also on the rise. Most of the new materials for interior decoration are organic compound materials, and in a closed indoor environment, different volatile organic compounds or even the same compound have different volatilization amounts at different times and are persistent. Among the interior decoration materials, from furniture such as wooden doors and windows, tables and chairs, to interior wall decoration materials, adhesives are used as the main decoration and protection materials, and the adhesives contain a large amount of formaldehyde. [0003] Formaldehyde is a volatile organic compound at room tempe...
