EFFECT:Capable of freely providing rough pattern owing to high viscosity.

Description

[Detailed description of the invention] The original F! J4#'i Water-based emulsion L made from styrene acrylic acid ester copolymer resin for exterior wall finishing materials for houses! ;3
This relates to an exterior wall finishing material that is mainly composed of silica and mixed with an external activator, a dispersant, a film-forming agent, and an aggregate.

Mortar is generally used to finish the exterior walls of houses, but mortar requires curing for about a week after construction, and has the problem of being prone to cracking and cracking.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an exterior wall finishing material that is fast-curing, has no curing, and is excellent in tank tank resistance.

The present invention will be explained in detail below. The exterior wall finishing material according to the present invention is mainly composed of an aqueous emulsion of styrene-acrylic acid ester copolymer resin that can be prepared using a vigitator, and further includes a surfactant, a dispersant, a film-forming aid, an aggregate, and other materials as necessary. It is obtained by blending thickeners and pigments according to the conditions; the surfactant is, for example, a thorium formalin condensate such as naphthalene sulfo, and the dispersant is, for example, a 10% aqueous solution of sodium metalysinate. As a film forming aid, for example, 2.2
．． 4-1-limethyl-1,3-becitadiol is used as a thickener, for example, a 2% water bath solution of 4-1-limethyl-1,3-becitadiol is used,
Examples of aggregates include calcium carbonate, titanium oxide,
Aluminum hydroxide trinilim is used.

Combination of each of the above components, Styrene resin, acrylic ester copolymer resin aqueous I Marujoshi 45-55% by weight (hereinafter abbreviated as "Hyaku"), surfactant 0.5-1.5-1, dispersant 0.5
~1.5%, glandular auxiliary agent 0.5-1.5%, thickener 0.5%
~1.5chi, aggregate 40-50%, pigment 0.5-1.5%
is unreasonable.

The exterior wall finishing material obtained by blending and mixing the above components can be applied to any exterior wall base such as mortar base with good visibility, and 111 cloth can be applied with a trowel, 0-roller, etc. . In addition, this exterior wall finishing material is fast-curing, hardens in 30 to 60 minutes, and does not require curing. Furthermore, it has excellent crack resistance and waterproof properties, and is also highly viscous. It is possible to freely create an uneven pattern.

Next, the present invention will be specifically explained using examples.

Example 1 50% of water as a binder, 50% of acrylic iron ester, 50% of water-based emulsion as a surfactant, and 50% of a water-based emulsion as a surfactant.
J-condensate 19&, he as a dispersant + lθ% aqueous solution of sodium sametalisinate l-1 as a film-forming agent 2.2.4
- 1% of trimethyl-1,3-hentadiol heptanoisoptylate, 1% of chloride as a thickener, 2% of Hill Methylcell, 1% of water solution, 2% of carbonic acid as an official material.
2.5 titanium, and titanium oxide'J22.596. Furthermore, by blending and mixing one pigment, an exterior wall finishing material was obtained.

This exterior wall finishing material adhered to the mortar base with good adhesion, hardened in 40 minutes, and did not require curing. It was left outside for a year under the Manoshichi Rutar base, and it did not peel off from the mortar and did not cause any cracks.

<Example 2> Exterior wall finishing material was obtained in the same manner as in Example 1, except that aluminum hydroxide was used instead of carbonate as the aggregate.
In addition to exhibiting all the same effects as in Monoke Example 1, it also had self-extinguishing properties due to aluminum hydroxide.
