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 an anti-cracking bonding mortar for wallboard connection. The anti-cracking bonding mortar is characterized by being prepared through mixing of the following raw materials byweight: 18-26 parts of hydrophobic fumed silica, 10-15 parts of zeolite powder, 6-12 parts of superfine slag powder, 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 superplasticizer, 5-10 parts of lotus leaf element, 10-15 parts of aluminum potassium sulfate, 5-10 parts of tall oil-asphalt sodium sulfonate, 8-16 parts of polypropylene glycol fiber, 3-5 parts of sodium bentonite, 2.5-4.5 parts of dicyclohexylamine nitrite, 3-5 parts of ethoxylated lanolin, and 4-7 parts of an assistant. The anti-cracking bonding mortarprovided by the invention has frost resistance, carbonization resistance and wear resistance superior to other cement. Compared with the existing formula, the formula adopted by the invention is addedwith zinc oxide powder, in the initial setting process, the bonding mortar neutralizes with water, acidic and alkaline substances, hydrogen and oxygen are gradually separated and are discharged fromthe bonding mortar in a gas form, at the same time part of hydration heat is taken away, thus reducing temperature shrinkage cracks.

Description

technical field [0001] The invention relates to the field of construction mortar, in particular to an anti-crack adhesive mortar for wall board connection. 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. A...
