Exterior wall external thermal insulation bonding mortar

Abstract

The invention discloses exterior wall external thermal insulation bonding mortar which is composed of the raw materials of, by weight, 20-30 parts of sulphoaluminate cement, 40-60 parts of quartz sand, 15-25 parts of yellow loam, 12-16 parts of soapstone powder, 2-3 parts of organosilicone powder, 3-5 parts of calcium phosphate, 16-22 parts of granular glass wool, 8-12 parts of rice bran powder, 2-3 parts of magnesium chloride, 0.5-1 part of hydroxyethyl cellulose, 1.5-2.5 parts of urea-formaldehyde resin gum powder, 0.5-1 part of sodium carboxymethyl starch, 1-2 parts of guar gum powder, and 3-6 parts of a composite filling material. The exterior wall external thermal insulation bonding mortar provided by the invention has the characteristics of high bonding strength, good thermal insulation performance, good cracking resistance, low water absorption rate, good water resistance, good weatherability, and the like. With the mortar, an obtained building exterior wall thermal insulation system can resist cracking, hollowing and chalking. The building exterior wall thermal insulation system also has the advantages of high adhesion strength with a wall body, good construction performance, good waterproofing effect, good mildew-resisting effect, and the like. With the exterior wall external thermal insulation bonding mortar, building exterior wall external thermal insulation requirements can be satisfied.

Description

technical field [0001] The invention relates to an external thermal insulation adhesive mortar for an exterior wall, which belongs to the field of building materials. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is used to construct the insulation layer of the building surface a building material. With the continuous promotion of low-carbon environmental protection and building energy conservation and the continuous improvement of people's demand for the comfort of the living environment, people pay more and more attention to thermal insulation mortar. Many applications, but compared with developed countries, the existing thermal insulation mortar for exterior walls still has problems such as poor thermal insulation effect, low adhesion strength, easy shrinkage and cracking, and easy mois...
