Abstract
The invention relates to colored decorative mortar with excellent performance. The raw materials of the decorative mortar includes double components, i.e., a dry component and a wet component, wherein the dry component consists of cement, emulsion powder, calcium carbonate, quartz sand, pigment and additives such as thickening agent, water repellent, defoamer and the like, and the wet component consists of polymer microemulsion and water. The decorative mortar provided by the invention has the advantages that the using amount of the cement is reduced, and meanwhile, nano-grade polymer microemulsion is creatively added so as to have excellent stain resistance due to extremely low surface energy on the surface of the mortar. All the performances of the decorative mortar obtained in the invention accord with the standard of JC/T1024-2007 wall decorative mortar; the decorative mortar has good coating compactness and no efflorescence or chromatic aberration phenomena after being exposed to the sun and rain outdoors for a long time, various kinds of plump mortar with bright colors can be obtained if different pigments are added; and the decorative mortar is very rich in model and remarkable in stain resistance so as to be particularly suitable for decorating outer walls of high-quality residences or vills.
Description
Technical field
The present invention relates to a kind of facing mortar that skin is played protection and decorative effect, relate in particular to a kind ofly in use without the accumulation of salt in the surface soil and aberration phenomenon, the colored finish mortar of the excellent performance of contamination resistance excellence belongs to building material field.
Background technology
Facing mortar is a kind of general name with wall plastering of decorative effect, and it is comprised of inorganic coagulation material, organic gel gel material, aggregate and various additive, is used for the decoration on construction wall surface.Facing mortar is owing to having a three-dimensional appearance of recovering one's original simplicity, and decorative effect is naturally unique, the cracking resistance of breathing freely, and good weatherability, and also coat-thickness can reach 1-3mm, can be processed into the grain surface of various styles.Facing mortar extensively replaces coating, ceramic tile in Europe, the material as architecture inside and outside decoration also begins to be applied in other countries and area gradually.But some problems usually hamper the development of this technology, and common problem comprises the accumulation of salt in the surface soil, and contamination resistance is poor, aberration, the problems such as cracking and construction.
The accumulation of salt in the surface soil be since the water soluble ingredient in the pore of top layer to move to the surface with pore water caused, when drying out, water soluble ingredient will form in material surface precipitation the stores of salt.And for contamination, analyzing from the mechanism of polluting roughly has following 4 kinds, 1. adheres to: when envrionment temperature is higher when especially being higher than the second-order transition temperature of organic gelling component polymer, easily be stained with ash, thereby cause contamination.2. suck: dust is dissolved in and becomes solution in the water or be dispersed in water the formation colloid, because there is a large amount of pores in the mortar surface, has certain water-absorbent, and these little particles can enter in the inner pore of mortar with water, form nonvolatil pollution; 3. absorption: mortar can adsorb dust and contaminated, and this surface energy with mortar is relevant, if can reduce the surface energy of mortar, can effectively reduce absorption; 4. dust stratification: mainly since the mortar surface irregularity cause.
Summary of the invention
The colored finish mortar that the purpose of this invention is to provide a kind of excellent performance, this colored finish mortar have excellent contamination resistance, and without the accumulation of salt in the surface soil, no color differnece has good mechanical property and resistance to deterioration simultaneously.
The colored finish mortar of the excellent performance that the present invention proposes, described colored finish mortar is two-component materials, the A component is comprised of cement, latex powder, dicalcium powder, sand, pigment and additive, the B component is comprised of polymer micro-emulsion and water, during use, A component and B component are mixed, get final product, component and mass fraction are as follows:
Cement 100
Latex powder 30-330
Dicalcium powder 0.1-900
Sand 1000-2600
Pigment 0-67
Additive 0-67
Polymer micro-emulsion 0.01-170
Water 150-800.
Among the present invention, described cement is white portland cement, or other kind white cements that meet the demands.
Among the present invention, described latex powder is the ethylene-vinyl acetate copolymer latex powder, other polymer emulsion powders that perhaps meet the demands.
Among the present invention, described dicalcium powder is 200-600 purpose dicalcium powder.
Among the present invention, described sand is quartz sand, other kind sand that perhaps meet the demands.
Among the present invention, described additive comprises hydrophober, thickening material and defoamer etc.
Among the present invention, the mass percent of described hydrophober, thickening material and defoamer is hydrophober 0.01-90%, ether of cellulose 0.01-70%, defoamer 0-30%.Among the present invention, described polymer micro-emulsion is the polyacrylic ester nanometer micro-emulsion, other microemulsions that perhaps meet the demands.
Facing mortar of the present invention has following advantage:
1, excellent contamination resistance.
2, without the accumulation of salt in the surface soil.
3, no color differnece.
4, ventilative again waterproof.
5, mechanical property is good.
6, without cracking.
7, color is full abundant, applied widely.
