Abstract
The invention discloses anti-crack thermal insulating mortar. The anti-crack thermal insulating mortar is composed of the following raw materials in parts by weight: 40-60 parts of ordinary Portland cement, 20-30 parts of mullite sand, 1.5-2.5 parts of polypropylene chopped fiber, 4-6 parts of ground steel slag, 10-15 parts of polystyrene foam particles, 5-10 parts of expanded perlite, 0.5-1 part of hydroxypropyl methyl cellulose, 3-5 parts of re-dispersible emulsion powder, 4-6 parts of polyvinyl alcohol, 3-7 parts of asbestos powder, 4-8 parts of diatomite, 2.5-4.5 parts of corncob powder, 3-6 parts of neopentyl glycol, 2-3 parts of sodium lignin sulfonate and 4-6 parts of composite filler. The thermal insulating mortar is relatively high in bonding strength and compressive strength and excellent in anti-cracking ability, and the defects of easy hollowing and cracking of the traditional thermal insulating mortar are overcome; meanwhile, the thermal insulating mortar has excellent properties such as thermal insulation property, waterproofness, weather fastness, acid-alkali corrosion resistance, freeze thawing resistance, aging resistance, mildew resistance and fire resistance, and has good construction performance, is green and environment-friendly, and safe and reliable, and has extremely large market space and development prospect.
Description
technical field [0001] The invention relates to a crack-resistant thermal insulation mortar, 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 on the market still has low strength, and it is easy to crack after solidification, which affects the overall appearance and thermal insulation effect.
