Embodiment 1

[0038] This embodiment provides a method for bonding building materials, and the specific steps are:

[0039] (1) Place the polystyrene board horizontally, and coat the bonding mortar with a thickness of 2mm on its surface;

[0040] (2) Immediately after the mortar coating is completed (the mortar remains plastic) on its surface at 1kg / m 2 Evenly spraying the polymer emulsion, the polymer emulsion covers 100% of the surface area of ​​the mortar surface;

[0041] (3) the rock wool board is directly covered on the mortar whose surface has been sprayed with the polymer emulsion;

[0042] (4) Wait for the mortar to solidify.

[0043] According to the standard "JG_T 483-2015 Rock wool thin plaster external wall external thermal insulation system material", the product obtained in this example is tested, and the tensile bond strength of rock wool is 0.14Mpa (standard requirement ≥ 0.08Mpa).

Embodiment 2

[0045] This embodiment provides a method for bonding building materials, and the specific steps are:

[0046] (1) Place the extruded board horizontally, spray polymer emulsion on its surface, and then coat a bonding mortar with a thickness of 8mm;

[0047] (2) Immediately after the mortar coating is completed (the mortar remains plastic) at a rate of 3kg / m 2 Evenly spraying the polymer emulsion, the polymer emulsion covers 100% of the surface area of ​​the mortar surface;

[0048] (3) The extruded board is directly covered on the wet mortar whose surface has been sprayed with the liquid interface agent;

[0049] (4) Wait for the mortar to solidify.

[0050] According to the standard "GBT 30595-2014 Extruded Polystyrene Board (XPS) Thin Plastered Exterior Wall External Thermal Insulation System Material", the product obtained in this example is tested, and the tensile bond strength of the extruded board is 0.23Mpa (standard requirement ≥ 0.2 MPa).

Embodiment 3

[0052] This embodiment provides a method for bonding building materials, and the specific steps are:

[0053] (1) Place the extruded board horizontally, spray polymer emulsion on its surface, and then coat a bonding mortar with a thickness of 5mm;

[0054] (2) Immediately after the mortar coating is completed (the mortar remains plastic) on its surface at 2kg / m 2 Evenly spraying the polymer emulsion, the polymer emulsion covers 100% of the surface area of ​​the mortar surface;

[0055] (3) The rock wool board is directly covered on the wet mortar whose surface has been sprayed with the liquid interface agent;

[0056] (4) Wait for the mortar to solidify.

[0057] According to the standard "JG_T 483-2015 Rock wool thin plaster external wall external thermal insulation system material", the product obtained in this example is tested, and the tensile bond strength of rock wool is 0.14Mpa (standard requirement ≥ 0.08Mpa).

Abstract

The invention relates to a bonding method for building materials. According to the method, the surface of the bonding material to be bonded on the bottom layer is coated with mortar, an adhesion agentis evenly sprayed to the surface of the mortar which is not coagulated, and then the adhesion agent is covered with the material to be bonded on the surface layer. According to the method, when two building materials are bonded, the traditional concept that interface treatment cannot be carried out on the surface of wet mortar is broken through, the adhesion agent is adopted for carrying out interface treatment on the mortar which is not coagulated, the strength of the original mortar is not damaged, the caking property of the mortar can be improved, and the building materials are firmly connected. Above all, the adhesion agent is directly sprayed to the mortar which is not coagulated, the procedure of carrying out interface treatment on the material to be bonded on the surface layer canbe omitted, places and time are saved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a bonding method for building materials. Background technique [0002] Mortar is a building material made by mixing sand, water, cement, etc., and various functions can be realized by adjusting the ratio. It is widely used in various fields related to construction. Among them, most of them use their excellent bonding properties to achieve bonding and repairing between various materials. The bonding property of mortar is to form a solid whole through hydration reaction, and achieve the bonding between materials through tiny mechanical locking with the materials to be bonded; however, in reality, many materials are not easy to achieve with cement mortar due to their surface characteristics. Therefore, there are materials on the market that add organic rubber powder or emulsion to the mortar and then use it for bonding to achieve a stronger bonding effect. [0003] However, in re...
