Transparent waterproof emulsion for outer wall and preparation method thereof

Abstract

The invention relates to the technical field of water-based acrylic acid waterproof emulsion preparation, in particular to transparent waterproof emulsion for an outer wall and a preparation method thereof, and the transparent waterproof emulsion comprises water, butyl acrylate, styrene, a cross-linking monomer, 2-ethylhexyl acrylate, a cross-linking assistant, an oxidizing agent, a reducing agent, a pH regulator, a defoaming agent, a preservative, an initiator, an emulsifier, a stabilizer and a special assistant. According to the transparent waterproof emulsion for the outer wall, the acrylic emulsion has strong ultraviolet resistance, and can improve the yellowing phenomenon of a coating film; the proper glass transition temperature can prevent the waterproof coating film from sticking dust and blackening in summer; the transparent waterproof emulsion has good film compactness, water resistance and water resistance recovery, has waterproof and breathable performance, and can avoid the phenomena that the waterproof film is whitened after being exposed to rain and the film is bulged and falls off after a period of time.

Description

Technical field [0001] The invention relates to the technical field of preparing water-based acrylic waterproof emulsion, specifically a transparent waterproof latex emulsion for exterior walls and a preparation method thereof. Background technique [0002] Water seeping from the exterior wall to the interior wall will cause a series of hazards such as mold on the wall and peeling of the wall skin. It is a common and troublesome thing in daily life. At present, most exterior walls are decorated with ceramic tiles and exterior wall maintenance is mostly done at high altitudes. In the field of work, in order to achieve good waterproofing effect without affecting the decorative surface effect, there is an increasing practice of using "transparent waterproof glue for exterior walls" for waterproofing repairs. [0003] Transparent waterproof glue for exterior walls is colorless and transparent. It can achieve waterproofing without affecting the decorative surface of exterior wall...

AI Technical Summary

Problems solved by technology

[0005] However, the existing products do not have good UV resistance, and the coating film is prone to yellowing; the waterproof coating film of some products will stick to dust and turn black in summer, and some products have poor water resistance. Poor etc., therefore, aim at proposing a kind of transparent waterproof glue emulsion and preparation method thereof for exterior wall
