Problems solved by technology

[0005] The disadvantage of the above-mentioned patent is that the attapulgite powder that has not been purified and modified is used as a filler in this technology, and the attapulgite powder only accounts for 1%-3% of the total amount (weight percentage), which is unable to hold water. The effect of steam, the thickening effect is also poor

Abstract

The invention discloses attapulgite outer wall emulsion varnish. The technical proposal comprises the following key points that: the attapulgite outer wall emulsion varnish consists of creamy attapulgite clay, styrene-acrylic emulsion, superfine heavy calcium carbonate, rutile type titanium pigments, hydroxyethyl cellulose, glycol, tributyl phosphate and deionized water. A production method of the attapulgite outer wall emulsion varnish comprises: compounding, crushing, stirring, dispersing, dissolving, homogenizing, emulsifying, defoaming, grinding, and canning into the finished product of the attapulgite outer wall emulsion varnish. The attapulgite outer wall emulsion varnish has the advantages of good adhesion, better weather resistance, water resistance and freeze-thaw resistance, safety, no toxicity and no pollution and belongs to environment friendly outer wall emulsion varnish. The attapulgite outer wall emulsion varnish is white standard paint, can be used for directly toning and producing various colorful paints, and is applicable to decorating buildings.

Description

technical field [0001] The invention relates to coatings, in particular to an attapulgite exterior wall latex paint. Background technique [0002] As an environmentally friendly paint, latex paint has been increasingly recognized by the construction and decoration industries. Latex paint uses water as a diluent. It is a paint that is easy to construct, safe, washable, and has good air permeability. It can be used according to Different color schemes deploy different colors. [0003] The basic performance of exterior wall latex paint is similar to that of interior wall latex paint, but the paint film of exterior wall latex paint is harder, with stronger water resistance, good gloss and color retention, and the requirement for anti-ultraviolet rays is much higher than that of exterior wall latex paint . [0004] Chinese patent authorization announcement number CN1304494, the date of authorization announcement is March 14, 2007, and the name is "environmental protection and h...
