Problems solved by technology

However, the concrete shear wall without plastering is very smooth, which will cause the failure or reduction of the bonding force between the mortar and the base surface, which will seriously affect the bonding effect between the mortar and the base layer, and there is a great potential safety hazard
The traditional treatment method is to chisel the wall to increase the bonding area between the mortar and the base layer, thereby improving the bonding force, but this method can only solve local problems, and the effect is not very satisfactory
[0003] In addition, during the construction of the external thermal insulation system, rock wool board and XPS board insulation materials are usually used in buildings, but these materials have the characteristics of water absorption, and the surface of this type of material is also very smooth, so it is necessary to brush the interface agent to Paste it on the wall, this method is more cumbersome, and the use of interface agent will also increase the cost of building materials
In addition, some on-site construction workers cut corners and omitted the interface agent painting step during the actual operation process, resulting in poor adhesion between the board and the mortar, resulting in safety accidents

Abstract

The present invention relates to the preparation method of two-component mortar, coating and thermal insulation system, wherein, two-component mortar comprises A component and B component; A component, by mass percentage, comprises the following components: cement 30 % to 55%, sand 35% to 60%, heavy calcium 5% to 10%, cellulose ether 0.1% to 0.3%, and additives 4% to 9.3%; wherein, the sand is composed of at least two different types of sand Mixture; component B, in terms of mass percentage, includes the following components: 15% to 35% of water-based fluororesin, 4% to 8% of penetrating agent and 60% to 78% of water; wherein, the penetrating agent is a surfactant . The above-mentioned two-component mortar has strong adhesion, and it can be directly bonded to smooth walls, XPS boards, rock wool products and other insulation materials without the need to apply interface agents. The bonding strength can meet the requirements of national industry standards. , can effectively reduce construction procedures, reduce system material costs and construction costs, and have high application value.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a preparation method of a two-component mortar, a coating and a thermal insulation system. Background technique [0002] At present, many projects under construction are constructed by assembling integrated formwork walls. Since the walls are prefabricated in the factory, the flatness of the outer wall base surface is good, and there is no need for plastering or partial plastering for leveling. However, the concrete shear wall without plastering is very smooth, which will cause the failure or reduction of the bonding force between the mortar and the base surface, which will seriously affect the bonding effect of the mortar and the base layer, and there is a great potential safety hazard. The traditional treatment method is to carry out chisel treatment on the wall to increase the bonding area between the mortar and the base layer, thereby improving the bonding force, but thi...
