Pure acrylic ester elastic emulsion

Abstract

The invention provides pure acrylic ester elastic emulsion. The pure acrylic ester elastic emulsion comprises, by weight, 140 parts of methyl methacrylate (MMA), 246 parts of butyl acrylate (BA), 4 parts of methacrylic acid (MAA), 6 parts of functional monmer A, 15 parts of allyl ether sulfonate, 5 parts of positive non-ionic emulsifier C, 1 part of ammonium persulfate (APS), 0.2 part of natrium acetate (NaAC), 0.3 part of ammonia water (25%), 0.1 part of sterilizing agent, 0.2 part of antifoaming agents and 360 parts of deionized water. The reaction emulsifier B is allyl ether sulfonate, acrylic amide sulfonate, maleic acid derivatives, allyl succinic acid allyl ester sodium sulfonate. The emulsion is good in heat preservation performance, and heat insulation performance, and strong in radiation resistance, washing resistance and adhesion force, and the extension performance can be more than 300%, and the emulsion can be applied to outer wall water resistance, heat insulation, and heat preservation, can directly replace ceramic tiles and other outer wall decorations, can also be applied to indoor places like washrooms and basements.

Description

technical field [0001] The invention relates to the technical field of paint, in particular to a pure acrylate elastic emulsion. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the building quality of the living room and the thermal insulation of buildings. Building energy consumption accounts for 30-40% of the total energy consumption. Most of these consumptions are used for Heating and cooling, building interior and exterior wall thermal insulation technologies are developing towards the integration of high efficiency, thin layer, heat insulation, waterproofing, and external protection. As an important part of building energy conservation, thermal insulation coatings have become the main subject of industry research; Most of the existing conventional interior and exterior wall coatings have defects such as poor filling, poor radiation resistance and sunscreen performance.

[0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the quality of the building and the thermal insulation of the building. The energy consumption of buildings accounts for 30-40% of the total energy consumption. Most of these consumptions are used for Heating and cooling, building interior and exterior wall insulation technology is developing towards the integration of high efficiency, thin layer, heat insulation, waterproof, and exterior protection. As an important part of building energy conservation, heat insulation coatings have become the main subject of industry research; Most of the existing conventional interior and exterior wall coatings have poor filling properties, poor radiation resistance and sun protection performance, and generally cracks will appear after about 3 months when painted on the exterior wall, short service life and poor heat preservation.
