Abstract

The invention discloses an anti-cracking heat-preserving wall construction material and a preparation method thereof. The anti-cracking heat-preserving wall construction material is prepared from, by weight, 400-600 parts of cement, 40-70 parts of silica powder, 80-220 parts of ash-calcium powder, 80-160 parts of expanded vermiculite, 60-100 parts of sand, 60-100 parts of hollow glass beads, 40-80 parts of rock wool threads, 30-80 parts of modified fly ash, 60-120 parts of polyphenyl particles, 10-20 parts of wood fiber, 5-10 parts of polypropylene fiber, 30-60 parts of polyvinyl alcohol, 40-80 parts of dispersible latex powder and 10-20 parts of cellulose ether. The anti-cracking heat-preserving wall construction material solves the problem that finishing mortar prepared from an existing outer wall heat-preserving material is prone to cracking and poor in durability, and truly achieves heat preservation, heat isolation and high anti-cracking performance.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation and crack-resistant wall building material and a preparation method thereof. Background technique [0002] The external thermal insulation system for building exterior walls can bring excellent energy-saving effects and a comfortable living environment, so people pay high attention to the long-term performance of the system. At present, the protective mortar used in the protective layer of the external wall external insulation system is mostly brittle cement-based materials with high specific gravity, high thermal conductivity, and high heat storage value; while the insulation boards are mostly organic insulation materials with low density and soft texture. Under long-term heat and cold, cold and humid cycles, repeated stresses, solar radiation, rain corrosion and other external erosion, there will be problems such as cracking, falling off, chalking, an...
