Adhesive mortar for external thermal insulation of external walls

Abstract

The invention discloses an external thermal insulation bonding mortar for external walls, which is composed of the following raw materials in parts by weight: 20-30 parts of sulfoaluminate cement, 40-60 parts of quartz sand, 15-25 parts of loess soil, 12-16 parts of saponite powder, Silicone powder 2-3, calcium phosphate 3-5, granular glass wool 16-22, rice bran powder 8-12, magnesium chloride 2-3, hydroxyethyl cellulose 0.5-1, urea-formaldehyde resin powder 1.5-2.5, carboxymethyl Sodium starch base 0.5-1, guar gum powder 1-2, compound filler 3-6. The external wall thermal insulation bonding mortar of the invention has the characteristics of high bonding strength, good thermal insulation, good crack resistance, low water absorption, good water resistance, good weather resistance and the like, and the obtained building external wall thermal insulation system has the advantages of no It has the advantages of cracking, no hollowing, no pulverization, high adhesion strength to the wall, good construction performance, good waterproof and mildew proof effect, etc., and can well meet the requirements of external thermal insulation of building exterior walls.

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...
