Problems solved by technology

[0006] However, the thin-layer alkali-resistant mortar has its defects. It is thin and has no measures to prevent water intrusion at the bottom layer, and it has lost the support of high-strength ordinary cement. Its strength is not enough, so it can only be used for emergency repairs and extreme environmental changes. work scene

Abstract

The invention discloses an anti-efflorescence facing mortar composite layer which comprises a first facing mortar layer, a second facing mortar layer and a third drainage layer. The first layer mainlycomprises silicate cement, quartz sand, calcium carbonate, rubber powder and additives, the second layer is mainly prepared based on a composite cementitious material system (HAC-OPC-CS), and the third layer mainly comprises water repellents and silicone-acrylic emulsion. By selecting and blending the cement, strength is improved, migration of liquid water molecules and calcium ions is stopped bya layer-by-layer filtering mechanism, and anti-efflorescence, sturdy and durable effects are achieved. The anti-efflorescence mortar composite layer has good adhesive force with an external wall surface base layer and is sturdy, durable and waterproof, a wall surface is simple and grand in color by adding pigments such as ferric oxide, and the mortar composite layer is suitable for decorating external wall insulation systems such as villas, buildings and caves.

Description

technical field [0001] The invention relates to the field of wall insulation materials, in particular to a composite layer of anti-efflorescence mortar. Background technique [0002] At present, the commonly used exterior wall decoration materials on the market are roughly divided into four systems: exterior wall tile system, exterior wall paint system, real stone paint system and exterior wall finishing mortar system. The four major systems have their own advantages and disadvantages. The building materials industry standard JC / T1024-2007 "Wall Finishing Mortar" clearly states that this standard is suitable for finishing mortars with a thickness not greater than 6mm. At present, the main direction of domestic research is focused on thin layers. For decorative mortar, the thickness is generally controlled below 3mm. This kind of thin-layer mortar is compatible with the external wall insulation system, and its decorative effect is similar to that of texture paint, so it is g...
