Problems solved by technology

[0005] The disadvantage of the above-mentioned patents 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 an attapulgite interior wall emulsion varnish. The key point of the technical proposal of the invention is that the attapulgite interior wall emulsion varnish consists of pastepalygorskite clay, acrylate emulsion, superfine precipitated calcium carbonate, anatase titanium dioxide, droxyethylcellulose, propanediol, tributyl phosphate, a fluorescent whitening agent VBL and deionized water. The method for producing the attapulgite interior wall emulsion varnish comprises the steps of material mixing, crashing, stirring, dispersion, dissolution, homogenization, emulsification, defoaming, grinding and canning to obtain a finished product of the attapulgite paste interior wall emulsion varnish. The attapulgite paste interior wall emulsion varnish has strong adhesive force, high durability, water resistance, scrubbing resistance and dirt resistance; the quality of the product is accordance with standards of 'GB / T 9756-2001 synthetic emulsion resin interior wall coating' and 'GB 18582-2008 hazardous substance limit quantity in interior decoration finishing material of interior wall coating'; and the attapulgite interior wall emulsion varnish is applicable to coatings for interior decoration.

Description

Technical field [0001] The invention relates to paint, in particular to an attapulgite internal 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 kind of paint that is convenient, safe, washable and has good air permeability. Different color schemes mix different colors. [0003] People will pay more attention to the decorative effect, film feel, flatness, color and texture of interior wall latex paint. Interior wall paint will have a greater impact on the indoor environment and should have proper air permeability and moisture absorption. A completely airtight and non-hygroscopic coating film will cause condensation on the wall, which is not conducive to the improvement of the indoor environment and the improvement of living comfort. The interior wall latex paint must not contain toxic and harmful substances, ...
