Abstract

The invention discloses a preparation method of a self-extinction matte emulsion with a gemini structure. The surface flatness of the paint film is reduced in the drying process through self-association of gemini surfactant groups on the polymer chain, the gloss is reduced, and the matte effect is generated. According to the method, a paint film with a matte effect can be obtained without adding extinction powder, the characteristics of low cost, high stability and the like, and a wide application prospect can be obtained.

Description

Technical field:

[0001] The invention relates to a preparation method of a self-extinction matte emulsion with a gemini structure, and belongs to the field of building materials and coatings for exterior walls. Background technique:

[0002] With the improvement of people's living standards, there are higher requirements for architectural coating. In order to further protect the exterior wall coating, the exterior wall architectural coating usually needs to be painted with water-based varnish after construction, so as to improve the weather resistance, stain resistance and special decorative effect of the coating. The current water-based varnishes mainly use water-based pure acrylic emulsion and fluorosilicon-modified acrylic acid as the main film-forming materials, which are characterized by smooth paint film and high gloss, but it is easy to produce light difference and blooming phenomenon in the process of large-scale construction . The emergence of water-based matte fi...
