Problems solved by technology

However, since the water-based emulsion uses water as a solvent, water evaporates slower than the solvent. When it is used in paint, it is prone to the problem of slow drying of the paint film.

Abstract

The invention provides a water-based emulsion, a preparation method of the water-based emulsion and a temperature-change-resistant construction real stone paint prepared from the water-based emulsion, and the water-based emulsion is prepared from the following raw materials in parts by weight: 400-700 parts of deionized water; 12 to 24 parts of an emulsifier; 150 to 300 parts of a hard monomer; 120 to 280 parts of a soft monomer; 10-20 parts of a carboxyl group-containing monomer; 10 to 20 parts of an inner cross-linking agent; 110 to 20 parts of a self-crosslinking monomer; 25 to 10 parts of a self-crosslinking monomer; 2-5 parts of a functional monomer; 1.5 to 3 parts of an initiator; 0.5-1 part of an oxidizing agent; 0.5-1 part of a reducing agent; the internal cross-linking agent comprises ethoxylated bisphenol A dimethacrylate; wherein the self-crosslinking monomer 1 comprises acetoacetic acid ethyl methacrylate, and the self-crosslinking monomer 2 comprises adipic acid dihydrazide. The water-based emulsion disclosed by the invention has a relatively high drying speed, and can be used for reducing the chromatic aberration of the dried real stone paint when being used for the real stone paint.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, and relates to a water-based emulsion and a preparation method thereof, and a real stone paint for temperature-change construction prepared by using the same. Background technique [0002] Natural stone is often used as a building decoration material because of its colorful and natural appearance. However, due to its heavy quality, increased wall load, complicated construction, many unsafe factors, high cost, excessive mining and damage to the environment, etc. , making its use highly restricted. The decorative effect of real stone paint is similar to natural stone, and it is mainly composed of various natural or artificial colored sand, high-performance emulsion and various additives. It has obvious advantages in sex and other aspects, and is suitable for indoor and outdoor decoration of various buildings. Real stone paint is gradually replacing traditional stone veneer materials an...
