Abstract

The invention discloses anti-cracking thermal insulation mortar. The anti-cracking thermal insulation mortar is prepared from the following raw materials in parts by weight: 4-6 parts of aluminum sulfate, 2-4 parts of alum, 14-17 parts of wood charcoal, 230-250 parts of perlite, 20-25 parts of pitchstone, 34-38 parts of obsidian, 30-40 parts of coal slime, 30-50 parts of coal ash, 3-4 parts of urea, 3-5 parts of monopotassium phosphate, 180-200 parts of cement, 40-50 parts of sepiolite fabric, 100-120 parts of sand, a proper amount of water and 20-25 parts of auxiliaries. The mortar has the advantages of good adhesiveness, water-retaining property and thermal-insulation and heat-insulation performance, outstanding thermal-insulation energy-saving effects, and further has excellent anti-cracking performance by use of the sepiolite fabric, is suitable for masonry and plastering construction of a wall material. By use of the auxiliaries adopted by the anti-cracking thermal insulation mortar, the compressive strength and the breaking strength of the mortar are improved, and the peaceability, the flow sagging resistance, the thixotropy and the settling resistance of the mortar are improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a crack-resistant thermal insulation mortar and a preparation method thereof. Background technique [0002] Mortar is a common material for construction and is an essential material in construction. According to performance, mortar can be divided into many types, such as combined mortar, caulking mortar, thermal insulation mortar, etc.; [0003] At present, the performance and quality of mortar are different, which affects the use. Specifically, the factors that affect the performance of mortar include the workability, fluidity, water retention of freshly mixed mortar, and the strength of hardened mortar. New mortars need to be researched to have excellent construction and processability, sag resistance, thixotropy, anti-settling properties, storage stability, improved pumpability and shear thinning, and new materials need to be found , in order to improve its per...
