Waterproof mortar

Abstract

The invention discloses waterproof mortar which is prepared from the following components in parts by weight: 30-50 parts of cement, 10-16 parts of blanc fixe, 5-8 parts of coal ash, 15-25 parts of abuilding waste recycled aggregate, 3-5 parts of sodium tetraborate, 2-4 parts of monopotassium phosphate, 4-8 parts of argil, 2-4 parts of redispersible latex powder, 3-5 parts of methylcellulose, 1-2parts of calcium stearate, 2-3 parts of sodium methyl silanol, 1-2 part of N,N'-methylene bisacrylamide, 1-2 parts of sodium oleate, 3-6 parts of composite filler and 1-3 parts of engineering cellulose. The waterproof mortar has excellent water resistance, waterproofness, permeable resistance, insulating and heat-isolating properties, chemical corrosion resistance and weather resistance, is highin strength, high in adhesive force, fireproof and flame-retardant, fully reliable, simple to construct and low in cost, and can be widely applied to insulating and waterproof engineering of interiorand exterior walls of a building.

Description

technical field [0001] The invention relates to the field of building materials, in particular to waterproof mortar. Background technique [0002] Thermal insulation and waterproof mortar is a kind of ready-mixed dry powder mortar made of various lightweight materials as aggregates, cement as the cementitious material, mixed with some modified additives, and mixed by the manufacturer. It is used to construct building surface insulation layer of 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 living environment comfort, thermal insulation and waterproof mortar has attracted more and more attention from people. There are many applications, but compared with developed countries, it still has problems such as poor water resistance, high water absorption, easy moisture absorption, water seepage and cracking.
