Abstract
The invention relates to a crystalline bloom resistant overcoating mortar, which contains the following constituents in parts by weight: 10-20 parts of general white cement, 0-15 parts of silicon oxide powder, 60-87 parts of quartz sand or color sand and 4-10 parts of additive, wherein the additive is composed of 0.2-1 part of magnesium oxide, 0-5 parts of inorganic iron oxide pigment, 0.2-0.3 parts of cellulose ether, 0.2-0.4 parts of water repellent, 0.01-0.03 parts of starch ether, 1.5-4 parts of rubber powder, 0.2-0.4 parts of ammonium carbonate, 0.1-0.4 parts of defoaming agent and the like. The development and application of the product can well solve the problem that the current overcoating mortar is easy to cause crystalline bloom, and the product can greatly reduce building repair expense, increase repair cycle and decrease repair cost and has remarkable technical and economical benefit.
Description
One, technical field:
The invention belongs to the material of construction class, a kind of facing mortar of the anti-accumulation of salt in the surface soil is provided.
Two, background technology:
The colored finish mortar is a kind of novel inorganic powder shape finishing material, and the inner, external wall that extensively replaces coating and ceramic tile to be applied to buildings is decorated.The colored finish mortar be with polymer materials as main additive, be equipped with that high-quality mineral aggregate, filler and natural mineral pigment are refining to form.
Cement based facing mortar particularly, owing to have nature, the characteristics of calcium carbonate and weather resistance are widely used in building exterior finish.Along with the development of additives such as polymkeric substance, the especially development of latex powder and some functional additives thereof is promoting colored finish mortar continuous advancement in technology.Emerged in large numbers and comprised the plural gel system, pure high alumina system is low/technology such as non-cement system.
The accumulation of salt in the surface soil is the modal problem of cement-based material, and the accumulation of salt in the surface soil the most common is the aquation by product Ca (OH) in the cement
2, under the appropriate climate condition, especially under the condition of low temperature and high relative humidity, migrate to the reaction of mortar surface and Carbon Dioxide in Air and generate white crystal, the i.e. accumulation of salt in the surface soil.Other soluble salt is moved to the surface simultaneously, also can form " the accumulation of salt in the surface soil " (white).The method of the most common inhibition accumulation of salt in the surface soil comprises: 1, and the water-intake rate of reduction mortar covers one deck sealing paint or varnish.2, adopt by high-alumina cement the plural gel system of gypsum and ordinary portland cement (comprising the active silica filler sometimes).3, pure high alumina system (or mixing a spot of ordinary portland cement); 4, add higher territory, silicon ash etc.
Yet because the Ca (OH) that the inner aquation of cement will inevitably produce
2, the accumulation of salt in the surface soil problem of facing mortar still fails to solve at present, has influenced its finishing effect, causes its engineering use range narrow.
Three, summary of the invention:
Technical problem to be solved by this invention be to overcome existing facing mortar existing above-mentioned shortcoming, a kind of facing mortar with good resistance accumulation of salt in the surface soil performance is provided.It is simple that the present invention has proportioning, improves the facing mortar quality, and easy construction reduces building maintenance cycle and maintenance cost, improves advantages such as buildings life-span.
To achieve these goals, technical scheme of the present invention is:
A kind of facing mortar of the anti-accumulation of salt in the surface soil, its component and content (weight) are: common white cement 10-20 part, silica powder 0-15 part; Silica sand or color sand 60-87 part, admixture 4-10 part is formed, and wherein admixture is made up of Natural manganese dioxide, inorganic oxide iron pigment, ether of cellulose, hydrophober, starch ethers, rubber powder, volatile salt, skimmer etc.; Be specially Natural manganese dioxide 0.2-1 part, inorganic oxide iron pigment 0-5 part, ether of cellulose 0.2-0.3 part; Hydrophober 0.2-0.4 part, starch ethers 0.01-0.03 part, rubber powder 1.5-4 part; Volatile salt 0.2-0.4 part, skimmer 0.1-0.4 part.
Described common white cement refers to satisfy the white portland cement of 4.25 grades.
Described silica powder is meant that staple is a silica powder, like silicon ash, silica flour or less than 120 purpose silica powders etc.
Described silica sand is meant size range 5-220 order, the silica sand of SiO2>=90-99%Fe2O3≤0.06-0.02%.
Described Natural manganese dioxide is meant that content of magnesia is the industrial goods greater than 80%.
Described inorganic oxide iron pigment is meant Fe2O3, %>=86; Screenings (320 order), %≤0.5; Water-soluble salt ,≤0.5% moisture, pigment such as≤1% yellow oxide of iron or red iron oxide.
Described ether of cellulose is meant one or more in methylcellulose gum (ether), CMC 99.5 (ether), carboxylic propyl methocel (ether), starch ethers or the carboxylic hexyl Mierocrystalline cellulose (ether).
Described hydrophober is meant one or more of siloyl group or organosilicon moisture repellent.
Described rubber powder is meant vinyl acetate and ethylene copolymer rubber powder (Vac/E); Ethene and vinylchlorid and month silicic acid vinyl acetate terpolymer rubber powder (E/Vc/VL); Vinyl acetate and ethene and higher fatty acid vinyl acetate terpolymer rubber powder (Vac/E/VeoVa); Vinyl acetate and higher fatty acid vinyl acetate copolymerization rubber powder (Vac/VeoVa); Propenoate and styrene copolymerized rubber powder (A/S); Vinyl acetate and propenoate and higher fatty acid vinyl acetate terpolymer rubber powder (Vac/A/VeoVa); Vinyl acetate homopolymerization rubber powder (PVac); In vinylbenzene and the butadiene copolymer rubber powder (SBR) one or more.
Described volatile salt is meant industrial marketable material.
Described skimmer is meant one or more of organo-siloxane, polyethers skimmer.
At first with Natural manganese dioxide, inorganic oxide iron pigment, ether of cellulose, hydrophober, starch ethers, rubber powder, volatile salt, mixed is even according to the rules for skimmer, add white cement, silica powder and silica sand then and mix and can obtain product.
Beneficial effect of the present invention is: 1. adopt white cement to mix the Ca (OH) that can impel hydrated cementitious to produce with silica powder and silica sand
2With the SiO2 reaction, reduced the basicity of system, reduce the source of the SiO2 accumulation of salt in the surface soil, and improved the intensity of product; 2. utilize comprehensive actions such as hydrophober, skimmer, rubber powder, entity system is able to densification, has reduced the SiO2 overflow channel, has suppressed the generation of the accumulation of salt in the surface soil greatly; 3. adopt Natural manganese dioxide and volatile salt and SiO2 reaction, form ZG 301.In a word, the development of the facing mortar of the anti-accumulation of salt in the surface soil can solve present facing mortar well with application and be prone to problems such as the accumulation of salt in the surface soil, can reduce the building maintenance expense greatly and improve maintenance cycle, reduces maintenance cost, has tangible technology and economic benefit.
