Problems solved by technology

[0003] Since colorful paint is a non-single-color product in which various particles are mixed and coexisted, its production cycle is long and the method is precise and complicated. Various problems often occur during the production process, and the stability of product batches cannot be guaranteed, making the product quality suffers greatly
[0004] At present, the multi-color paint particles on the market have insufficient toughness, poor high-shear stability, and the color dots are easily broken after spraying. At the same time, it is difficult to carry out large-scale production. This is mainly related to the raw material acrylate emulsion in the multi-color paint.

Abstract

The invention discloses an acrylate microemulsion and a preparation method thereof, which are applied to colorful paint. The acrylate microemulsion comprises the following components in parts by weight: 100 parts of deionized water, 2-8 parts of a compound emulsifier, 20-50 parts of methyl methacrylate, 20-60 parts of 2-ethylhexyl acrylate, 20-50 parts of butyl methacrylate, 2-8 parts of an acid monomer, 1-3 parts of an amine monomer and a crosslinking monomer, 0.1-0.5 part of an initiator and 1-2 parts of a pH regulator. The acrylate microemulsion prepared by the preparation method disclosed by the invention has relatively good particle toughness and high shear stability.

Description

technical field [0001] The invention relates to the technical field of architectural colorful coatings, in particular to an acrylate microemulsion and a preparation method thereof. Background technique [0002] As a kind of imitation granite coating, multi-color coating is light in weight and easy to construct, which solves the defects of granite self-heavy and difficult construction. At the same time, multi-color coating also has the characteristics of washing resistance, dirt resistance, strong wear resistance, and strong acid and alkali resistance. Therefore, it is widely used in cement, stone surface, brick, wood, metal and other surfaces as decoration. [0003] Since colorful paint is a non-single-color product in which various particles are mixed and coexisted, its production cycle is long and the method is precise and complicated. Various problems often occur during the production process, and the stability of product batches cannot be guaranteed, making the product ...
