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 anticrack adhesive mortar. The mortar is characterized in that the mortar is prepared by mixing, by weight, 18-26 parts of hydrophobic fumed silica, 10-15 parts of zeolite powder, 6-12 parts of ore slag micropowder, 4.5-6.5 parts of 2-phosphonobutane-1,2,4-tricarboxylic acid, 9-18 parts of zinc oxide powder, 20-30 parts of an AF-2 type high-efficiency water reducer, 5-10 parts of a material named as Chinese characters 'Heyesu' by the inventor, 10-15 parts of aluminum potassium sulfate, 5-10 parts of tall oil-pitch sodium sulfonate, 8-16 parts of poly(methyltriethoxysilane), 3-5 parts of calcium sorbate, 2.5-4.5 parts of dicyclohexylammonium nitrite, 3-5 parts of ethoxylated wool fat and 4-7 parts of an auxiliary agent; freezing resistance, carbonization resistanceand wear resistance of the mortar are superior to those of other cement; compared with present formulae, the zinc oxide powder is added into the formula and neutralizes with water, acid and alkali compounds in an initial set process of the adhesive mortar, hydrogen and oxygen are gradually separated, and form a gas; the gas is discharged from the mortar and takes away a part of heat of hydration;and shrinkage cracks caused by temperature changes are reduced.

Description

technical field [0001] The invention relates to the field of construction mortar, in particular to an anti-crack 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 ...
