Problems solved by technology

[0010] In the prior art described above, these adhesive pastes can be bonded to organic foam plastic insulation boards, all of which can ensure firm adhesion, convenient and quick construction, can reduce labor intensity, and improve the working environment. Due to the characteristics of its own structure, leakage often occurs during use, especially in rainy weather, which seriously affects and restricts the application of adhesive paste, especially not suitable for prefabricated buildings

Abstract

The invention relates to a waterproof bonding mortar. The waterproof bonding mortar is characterized by being prepared from the following raw materials by weight through mixing: 18 to 26 parts of hydrophobic fumed silica, 10 to 15 parts of calcium stearate, 6 to 12 parts of slag micropowder, 4.5 to 6.6 parts of 2-phosphonobutane-1,2,4-tricarboxylic acid, 9 to 18 parts of zinc oxide powder, 20 to 30 parts of an AF-2 type superplasticizer, 5 to 10 parts of glass fibers, 10 to 15 parts of aluminum potassium sulfate, 5 to 10 parts of tallol oil-asphalt sodium sulfonate, 8 to 16 parts of polymethyltriethoxysilane, 3 to 5 parts of calcium sorbate, 2.5 to 4.5 parts of dicyclohexyl amine nitrite, 3 to 5 parts of ethoxylated lanolin and 4 to 7 parts of an auxiliary agent. The waterproof bonding mortar provided by the invention has better frost resistance, carbonization resistance and wear resistance than other cement. Compared with traditional formulas, zinc oxide powder is added in the formulafor the waterproof bonding mortar; and during initial setting, the bonding mortar is neutralized by water and acidic and alkaline substances, so hydrogen and oxygen are gradually separated and becomegases that are discharged from the bonding mortar, and at the same time, a part of hydration heat is taken away, thereby reducing shrinkage cracks caused by temperature changes.

Description

technical field [0001] The invention relates to the field of construction mortar, in particular to a waterproof adhesive mortar. Background technique [0002] At present, with the increase of national building energy conservation efforts, the application of external wall insulation technology has also been enhanced, and its important component - bonding mortar has been widely used. [0003] Adhesive mortar is a kind of dry-mixed mortar prepared by mixing and homogenizing suitable polymer admixtures according to different insulation systems, especially insulation materials. Due to the addition of a certain polymer admixture in the adhesive mortar, it has good adhesion, water resistance and other properties. [0004] Traditional bonding mortar is usually divided into two types: single-component type and multi-component type. Single-component refers to that the mortar manufacturer mixes and homogenizes multiple components and packs them into bags. Add water to the amount of w...
