CN102533031A - External wall paint of building - Google Patents

Abstract

The invention provides external wall paint of a building, which comprises the ingredients of acrylic copolymer emulsion, polyethylene wax emulsion, thickening agents, dispersing agents, lignin, butyl acetate, white carbon black, kaolin, ethylene glycol, hydroxyethyl cellulose and water. The external wall paint has the characteristics of environmental-friendly effect, high flexibility and high luminance brightness.

Description

Skin coating

Skill wood field

The wood invention belongs to building material field, and the skin coating of a kind of high fineness, high-flexibility, high cracking resistance is provided.

Technical background

Exterior coating belongs to material of construction, will consider mechanical property, endurance quality, fire prevention-fire performance, health performance, flexility, alkali resistance, water resistance, appearance property, production, workability and environmental-protecting performance etc. usually to it.To the development of high performance outer wall paint, many inventors have proposed solution.

Like Chinese patent " CN1407038 external wall coating mortar " a kind of exterior coating is provided, available mud plate is directly pressed and is smeared.Have characteristics such as a large amount of cement of saving, once completion is covered with paint, lacquer, colour wash, etc., production technique is simple.Chinese patent " CN1431266 multifunctional nano building external paint and preparation method thereof " provides a kind of multifunctional nano building external paint, and main ingredient is: water, Sodium hexametaphosphate 99, nano TiO 2, nano-ZnO, nanometer SiO2, white titanium pigment etc.Process through special process, have stronger abrasion resistance and self-cleaning antibacterial.It is Z 150PH, high-intensity fiber element, water, talcum powder, fine particle calcium carbonate etc. that Chinese patent " CN1453318 high-strength antifoulant wall paint " provides a kind of high-strength antifoulant wall paint, main ingredient, has hardness height, water-fast characteristics such as wash, do not ftracture.

Prior art has all obtained certain progress at aspects such as saving material, raising self-cleaning, raising abrasion resistance, but also exists not enough.Mainly show as: 1, the feature of environmental protection is poor, produces environmentally harmful waste material waste gas etc. in process of production; 2, snappiness is poor, is prone to produce cracking or peel off, and has a strong impact on outward appearance and other performance; 3, particle diameter is bigger, and fineness and surface brightness are poor.

Summary of the invention

Based on above understanding, the purpose of this invention is to provide a kind of exterior coating, this exterior coating has the characteristics of environmental protection, high-flexibility, high brightness.

For achieving the above object, the present invention is based on following technical scheme: 1, the reaction that takes place in process of production of selected raw material does not produce gaseous matter, and reaction carries out at low temperatures, has avoided material gasification; 2, adopt xylogen, Natvosol to improve the snappiness of coating; 3, adopt kaolin, polythene wax emulsion, reduce particle diameter, significantly improve fineness and surface brightness.

The mass fraction of each component is among the present invention:

Acrylate copolymer emulsion 8～25%

Polythene wax emulsion 2～6%

Butylacetate 5～10%

Terepthaloyl moietie 3～8%

Thickening material 0.3～1%

Dispersion agent 1～3%

Natvosol 0.5～1%

Xylogen 8～22%

White carbon black 5～15%

Kaolin 10～25%

Water 30～50%

Embodiment

Below be a kind of embodiment of the present invention, each constituent mass mark does

Acrylate copolymer emulsion 10%

Polythene wax emulsion 5%

Butylacetate 7%

Terepthaloyl moietie 5%

Thickening material 0.5%

Dispersion agent 1.5%

Natvosol 1%

Xylogen 10%

White carbon black 12%

Kaolin 10%

Water 38%

Compound method is: under stirring at low speed, make it high dispersing by thorough mixing in the order adding container of water, terepthaloyl moietie, Natvosol, white carbon black, acrylate copolymer emulsion, polythene wax emulsion, thickening material, dispersion agent; Adding xylogen, butylacetate, kaolin then mixes; Put into sand mill to gains and grind, fineness reaches request for utilization and gets final product.
