Problems solved by technology

[0014] The purpose of the present invention is to solve the common quality problem that the insulation layer and the cement mortar outer protective layer or the concrete outer protective layer are not bonded to each other, and cracks are caused by hollowing, and to solve the problem that the inner and outer layers of concrete and the middle insulation layer cannot be bonded to each other. Work problems; solve the problem of plaster cracking and falling off on ordinary components, especially on smooth concrete components; and solve the quality problems of increasing the bonding strength of the bonding interface and avoiding the falling off of facing bricks when pasting facing bricks

specific Embodiment approach 1

[0020] Specific Embodiment 1: A construction method in which an interface agent of this embodiment is used for plastering crack resistance and increasing the adhesive strength of plastering and facings, the construction method is to brush or spray the first interface agent during construction To the surface of the wall or floor insulation layer, brush or spray the surface area of ​​the wall or floor insulation layer to not less than 30%, and in the wet state of the first interface agent, plaster the cement mortar to the surface of the wall or floor insulation layer, Or just pour concrete onto the surface of the wall or floor insulation layer. The wall or floor insulation layer is a polymer insulation layer, a mineral wool board, a plant straw board, or a perlite board.

specific Embodiment approach 2

[0021] Specific embodiment two: the difference between this embodiment and specific embodiment one is: this embodiment also adds a second interface agent, and the construction method is that after the first interface agent on the wall or floor insulation layer is dried, Brush or spray the second interface agent again, and in the wet state of the second interface agent, plaster the cement mortar to the surface of the wall or floor insulation layer, or pour concrete onto the surface of the wall or floor insulation layer. The first interface agent and the second interface agent are formed by mixing water-soluble adhesive, water, cement, water-retaining agent and ultrafine powder in proportion by weight. Water-soluble adhesive: water: cement: water-retaining agent: super Fine powder=1:1~10:0~15:0~0.1:0~10.

[0022] The quality of the interface agent painted on the wall or floor insulation layer is qualified if it meets the bonding strength test. The factors that affect the bonding...

specific Embodiment approach 3

[0024] Specific embodiment three: a kind of interface agent of this embodiment is used for the construction method of plastering and crack resistance, increasing the adhesive strength of veneer, and described construction method is to brush or spray the first interface agent to block shape during construction. On the side of the insulation board, under the wet state of the first interface agent, squeeze the block insulation boards tightly to install and bond; or pour cement mortar or concrete on the side of the block insulation board, and bond the block insulation board as a whole , the block insulation board is a polymer insulation layer, a mineral wool board, a plant straw board, and a perlite board.

Abstract

The invention relates to a construction method for using an interface agent to prevent a floated coat from being cracked and increase the bonding strength of the floated coat and a veneer, which relates to a construction method and aims to solve the common problems of cracking and hollowing of the floated layer and low bonding strength of the floated coat and the veneer. The first proposal is as follows: the interface agent is coated on a heat-insulating layer of a wall body or a floor, and cement mortar plastering or concrete placing is performed when the interface agent is wet. The second proposal is as follows: the interface agent is coated on the side face of a heated board which is squeezed up when the interface agent is wet, or the side face of the heated board is subjected to cement mortar plastering or concrete placing and the heated board is bonded. The third proposal is as follows: the interface agent is coated on a building element, and cement mortar plastering or face tile plastering is performed when the interface agent is wet. The fourth proposal is as follows: the interface agent is coated on face tiles, and bonded mortar is used for plastering the face tiles when the interface agent is wet. The construction method can effectively solve the problem of hollowing and cracking of the cement mortar or concrete and increase the bonding strength of the floated coat and the veneer.

Description

technical field [0001] The invention relates to a construction technique for plastering to prevent cracks and increasing the adhesive strength of plastering and facings. Background technique [0002] Common quality problems of cement mortar plaster cracking or even plaster falling off often occur in construction projects, mainly manifested in the following three situations: [0003] 1. The cement mortar plastering protective layer of the composite thermal insulation component or the concrete and the polymer thermal insulation layer cannot be bonded to each other, and cracks are often caused by hollowing. Such as: [0004] Most of the insulation layers installed in wall insulation and energy-saving technologies are polymer insulation materials, such as molded polystyrene boards (EPS boards), extruded polystyrene boards (XPS boards), polyurethane boards, etc. The outer side of the layer often needs to be plastered with a cement mortar protective layer, such as the outer side...
