High performance mortar for EPS decorative lines

Abstract

The invention discloses a high performance mortar for EPS decorative lines. The mortar comprises a liquid part and a powder part, wherein the liquid part comprises an acrylic emulsion, water and an anti-foaming agent, and the powder part comprises cement, quartz sand, a thickener, a water reducing agent, and an early strength agent. The EPS decorative lines prepared by the high-performance mortarformulation can greatly improve the flexibility, and have impact resistance without cracking, good durability, and waterproof performance; and the EPS decorative lines have no air-entraining expansion, no collapsing, and easy shaping, so that the EPS decorative lines are very suitable for continuous automation production.

Description

technical field [0001] The invention belongs to the technical field of mortar, in particular to a high-performance mortar with EPS decorative lines. Background technique [0002] EPS decorative lines can be fireproof and will not emit toxic substances. It is an environmentally friendly high-quality decorative building material product. It is a new type of exterior wall decoration line and component, which is more suitable for installation. On the exterior wall of EPS insulation, it can not only reflect the European classical and elegant decoration style, but also ensure that the exterior wall of the main building does not appear cold or hot. bridge effect. It has the advantages of convenient installation, economy and long durability. [0003] Compared with GRC cement lines and gypsum lines, EPS lines are light in weight, easy to install, diverse in variety, good in durability, energy-saving and environmentally friendly, and have great advantages. They have been widely used...

Problems solved by technology

[0003] Compared with GRC cement lines and gypsum lines, EPS lines are light in weight, easy to install, diverse in variety, good in durability, energy-saving and environmentally friendly, and have great advantages. They have been widely used in the market, but the EPS carcass currently on the market The mortar formula generally uses redispersible latex powder as the raw material of modified mortar. The disadvantage is that there is a bottleneck in the improvement of flexibility, and it can only achieve the degree of folding ratio <4. Some people also try to use polyvinyl acetate emulsion or acrylic emulsion When the modified mortar is used as the cover material, there will be problems such as demulsification due to the mismatch between the inorganic material and the organic material, and in actual production, it will cause early setting, and a large amount of gas will be introduced, which will make the mortar hardness too high, resulting in product failure. large deformation

At the same time, the products produced by using the existing mortar formula for EPS lines have many defects such as brittleness, non-waterproof, poor freeze-thaw resistance, etc.
