Abstract

The invention relates to the field of preparation of acrylate emulsions, in particular to an economical general-purpose styrene-acrylic emulsion for interior and exterior walls and a preparation method thereof. The economical general-purpose styrene-acrylic emulsion for interior and exterior walls is prepared from the following raw materials in parts by weight: 300-400 parts of styrene, 150-300 parts of butyl acrylate, 100-200 parts of isooctyl acrylate, and 10-25 parts of acrylamide , 5-20 parts of acrylic acid, 1-5 parts of methacrylic acid, 1-5 parts of silane coupling agent, 5-20 parts of emulsifier, 1-5 parts of persulfate, 1-5 parts of alkyl mercaptan, pH adjustment 2-10 parts of agent, 650-850 parts of water. The emulsion provided by the invention has excellent wettability and dispersibility for pigments and fillers and good adhesion to substrates, and the latex particles are small, and it has good scrub resistance in the interior wall formula and at the same time it can be used on the exterior wall It also has excellent paint thickening responsiveness and color development.

Description

Technical field: [0001] The invention relates to the field of preparation of acrylate emulsions, in particular to an economical general-purpose styrene-acrylic emulsion for interior and exterior walls and a preparation method thereof. Background technique: [0002] In recent years, with the rapid development of my country's real estate industry, the market's demand for water-based acrylic coatings has also increased; this has also brought opportunities to many small and medium-sized acrylic emulsion manufacturers, making the current environmental situation extremely fierce. Various fields and types of products tend to be homogeneous, and the differences are getting smaller and smaller. Therefore, while bringing about the development of water-based coatings in the real estate industry, it also makes various medium and large enterprises face more challenges. [0003] Cost-effective products are still the mainstream elements currently occupying the market, because it is not easy...
