Abstract
The invention provides high-performance wall facing mortar. The mortar consists of white cement, quartz sand, acrylic re-dispersible glue powder and other various assistants. Because of the adoption of the acrylic glue powder with excellent ageing resistance and water absorption resistance, the facing mortar prepared through design and optimization of a formulation not only has excellent performance such as adhesive performance, compressive strength, breaking strength and the like, but also has good ageing resistance and salt-petering resistance, and can be widely applied to decoration of building walls.
Description
Technical field
The present invention relates to a kind of construction wall and use facing mortar, relate in particular to a kind of high-performance facing mortar that the interior exterior wall of buildings plays decoration function that is used for.
Background technology
The construction wall finishing material mainly contains exterior coating, face brick and all kinds dalle etc. at present.Facing mortar is a kind of novel construction wall finishing material that rises gradually in recent years; It mainly is made up of cement, silica sand, filler, pigment and other additive; Can be widely used in various building walls surface; Compare materials such as face brick, dalle, facing mortar has advantages such as light weight, with low cost and easy construction; Compare exterior coating; Because facing mortar belongs to inorganic system, gelling material wherein adopts materials such as cement more, and performances such as its thermodynamics are close with the exterior wall mortar; Therefore with outer wall heat preservation system and body of wall better compatible matching is arranged, advantages such as better weather resistance.
Yet also there is some self defective in facing mortar, and as being prone to the accumulation of salt in the surface soil, during as external wall decorative material, color is selected shortcomings such as limited, and in order to overcome these shortcomings, the investigative technique personnel in the industry have also taked various means and method to study.Chinese patent CN101475354A discloses a kind of anti-crystalline bloom exterior wall facing mortar, and the said facing mortar of patent mainly adopts the high-alumina cement system as gelling material, suppresses water-soluble salt Ca (OH)
2Generation, realizing the purpose of the anti-accumulation of salt in the surface soil, adopted high-alumina cement as inorganic coagulation material but the shortcoming that this facing mortar exists is, and the relative ordinary portland cement of high alumina is on the high side, causes this kind facing mortar price higher.Chinese patent 200910048498 discloses a kind of body of wall colored finish mortar, and this mortar can be used for vitrified micro-bead heat preserving system surface as finishing material.The described facing mortar system of above-mentioned patent, but the shortcoming that this facing mortar exists is that this mortar is not a kind of universal facing mortar, only is exclusively used in vitrified micro-bead heat preserving system surface, and there is restriction in range of application.
Summary of the invention
The purpose of this invention is to provide a kind of wall facing mortar, make that it is not only cheap, applied range but also have good adhesiveproperties, good anti-folding, ultimate compression strength, excellent durability can property and anti-accumulation of salt in the surface soil property.
In order to achieve the above object, technical scheme of the present invention has provided a kind of wall facing mortar, it is characterized in that, forms as follows in the raw material of weight part:
White cement 20-30;
Silica sand 35-55;
Re-dispersible glue powder 20-30;
Coarse whiting 10-25;
Ether of cellulose 0.1-0.5;
Lignocellulose 0.4-0.6;
Hydrophober 0.2-0.4;
Mineral dye 0.5-3.
Further, white cement is preferably 325 or 425 white cements.
Silica sand is preferably one or both in 20-40 order silica sand, 30-50 order silica sand, 40-70 order silica sand, 50-100 order silica sand or the 70-140 order silica sand.
Re-dispersible glue powder is preferably the vinylformic acid rubber powder.
Coarse whiting is preferably 200 purpose coarse whitings.
Ether of cellulose is preferably viscosity at the methyl cellulose ether below 10000.
Hydrophober is preferably the hydrophober of organosilicon type.
Mineral dye is preferably a kind of in iron oxide black, iron oxide yellow, iron oxide red, cobalt blue or the ultramarine.
High-performance wall facing mortar of the present invention is the inorganic gel material with the white cement, adopts the modification of vinylformic acid re-dispersible glue powder; The silica sand, coarse whiting and other auxiliary agent that add different gradation are formulated; Because the vinylformic acid re-dispersible glue powder is compared EVA rubber powder commonly used, excellent in water resistance ability and ageing-resistant performance are arranged, can guarantee that facing mortar has good bonding strength and ageing-resistant performance; Through studying its different addition; Facing mortar solidifies back vinylformic acid rubber powder can form the successive rete therein, cooperates and adds material and grating silica sand, can effectively stop or reduce the migration of salt; Thereby can guarantee the anti-accumulation of salt in the surface soil performance that it is good; In addition, owing to adopted high performance white cement and silica sand, can guarantee that through adjustment prescription composition facing mortar of the present invention has physicalies such as excellent anti-folding, resistance to compression.
