CN1407038A - External wall coating mortar - Google Patents

Abstract

A mortar-type paint for external wall is disclosed, which is prepared through mixing and stirring. Its advantages are convenient application, and saving cement.

Description

A kind of external wall coating mortar

The present invention relates to a kind of exterior coating, is that bricklayer is directly pressed the exterior coating of smearing with the mud plate.

Along with the develop rapidly of Building Trade in China, decoration of exterior wall is also being brought in constant renewal in.The kind of exterior coating is increasing, is constantly replacing outdoor tile, stone material veneer.Coating application method is simple, speed is fast, and its weak point is that the exterior wall substrate surface needs to handle.Normally adopt concrete wall surface, thickness is 1.5～2.0 centimetres, need smear two～three times and just can finish, and consume a large amount of artificial and materials.

The coating of domestic production at present all be adopt brush, roll, scrape, method coverings with paint such as bullet, spray.Particularly bullet, spray method need pressurized air, and construction process can cause atmospheric pollution.

The objective of the invention is to produce a kind of external wall coating mortar, adopt watt the mode of plastering to cover with paint, lacquer, colour wash, etc., therefore less demanding to the substrate surface of body of wall, only need get final product with cement mortar screeding, can save a large amount of cement, and once finish covering with paint.

Purpose of the present invention can realize by the following method: a kind of external wall coating mortar, mainly form by filmogen adding pigment, aggregate, attached material and the water of helping.Its weight proportion is:

Water: 8～12%

Natvosol: 0.2～0.4%

Lime carbonate: 1～3%

Acrylate polymer emulsion: 20～30%

Ethylene glycol: 0.3～0.5%

Alcohol ester: 0.02～0.04%

Defoamer: 0.1～0.2%

Ammoniacal liquor 27%: 0.1～0.2%

Sanitas: 0.02～0.04%

Dispersion agent: 0.1～0.2%

Silica sand: 60～70%

Pigment: 2～4%

Wherein the granularity of silica sand is #14～#80, and pigment is alkaline-resisting, fast to light mineral pigment.

Because adopting acrylate polymer emulsion is filmogen, to be that coating film gloss is gentle close its outstanding characteristics, and weathering resistance, gloss retention, tint retention are all very excellent.Construction temperature is as long as guarantee more than 4 ℃.Production technique is simple, can make product as long as mix to stir, and only covers with paint, lacquer, colour wash, etc. and need once smear and can finish.

Embodiment: the prescription when construction temperature is low

Water: 8%

Natvosol: 0.3%

Lime carbonate: 0.2%

Acrylate polymer emulsion: 30%

Ethylene glycol: 0.4%

Alcohol ester: 0.04%

Defoamer: 0.1%

Ammoniacal liquor 27%: 0.1%

Sanitas: 0.02%

Dispersion agent: 0.2%

Silica sand #14: 6%

#60 ：30％

#80 ：34％

Pigment: 3%

Result of implementation shows: satisfy the requirement of external wall to coating fully, construction is simple, saves human and material resources.
