Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with embodiments.

[0036] The preparation process of the acrylic emulsion used in the water-based colorful paint of the present invention is as follows:

[0037] (1) Prefabricated core layer emulsion: sequentially add 150-250 parts of water, 3-5 parts of alkyl polyoxyethylene ether anionic emulsifier, 30-50 parts of styrene, and n-butyl acrylate to the emulsion reactor I 100-250 parts of ester, 100-250 parts of isooctyl acrylate, 50-100 parts of methyl methacrylate, 5-10 parts of methacrylic acid. Stir thoroughly for 1 hour to obtain a stable pre-emulsion. Preferably, the water, alkyl polyoxyethylene ether type anionic emulsifier, styrene, n-butyl acrylate, isooctyl acrylate, methyl methacrylate, and methacrylic acid are sequentially added to the first emulsion reactor. The numbers are: 200, 4, 40, 200, 200, 80, 8; or 180, 3, 35, 180, 180, 60, 6; or 220, 5, 45, 220, 220, 70, 9; or 160, 4, 48, 160, 180...

Abstract

The invention discloses an acrylic emulsion for water-based colorful paint and its preparation process, which belongs to the technical field of architectural paint research and development. The process includes the steps of prefabricated core layer emulsion, prefabricated shell layer emulsion and initiator, and then using the prefabricated core layer emulsion , shell emulsion and initiator synthesis to prepare colorful acrylic emulsion. The synthesis process of this process is carried out at low temperature using a redox initiator, the surfactant used is an alkyl polyoxyethylene ether anionic emulsifier containing EO chain segments, and the structure of the emulsion is designed to be a core-shell structure. The water-based multicolor paint prepared by the invention has greatly improved water resistance, and has excellent storage stability, the viscosity of the paint is not thick during storage, and the performance is excellent.

Description

Technical field [0001] The invention belongs to the technical field of architectural paint research and development, and relates to an architectural emulsion and a synthesis process thereof, in particular to an acrylic emulsion for water-based colorful paint and a preparation process thereof. Background technique [0002] In recent years, as a new type of architectural coating, water-based colorful coatings have become the best in the field of architectural exterior wall decoration due to their simple construction process, high cost performance, various color patterns after drying, and realistic appearance close to granite and marble. Popular products are quite popular among paint manufacturers and consumers. The continuous phase film-forming emulsion obtained by conventional emulsion polymerization plays a vital role in the final properties of the colorful coating, such as water resistance, stability, transparency and thick coating cracking. Styrene-acrylic, pure acrylic, silic...
