Abstract

The invention discloses crack-resistant thermal insulation mortar which consists of the following raw materials in parts by weight: 35-45 parts of common Portland cement, 20-30 parts of Mullite sand, 5-10 parts of diatomite, 4-8 parts of desulfurized fly ash, 3-6 parts of talcum powder, 40-50 parts of glass beads, 3-5 parts of micro-calcium silicate, 2-3 parts of polypropylene fiber, 1-2 parts of polyester fiber, 2-3 parts of polyvinyl acetate homopolymerization rubber powder, 0.4-0.8 part of hydroxyethyl cellulose ether, 3-5 parts of sodium polyacrylate, 2-3 parts of calcium lignosulphonate, 0.3-0.5 part of naphthalene water reducer and 4-6 parts of thermal insulation particles. The thermal insulation mortar is excellent in performance, can overcome the common problems such as cracking and flakes, is high in bonding strength and high in adhesive force, has excellent performances such as high thermal insulation property, weather resistance, high fire and water resistance and freezing resistance and is wide and readily available in raw material source, low in production cost, convenient in construction and wide in application 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 mainly used to construct building surface insulation As a kind of building material, it has the characteristics of energy saving and waste utilization, thermal insulation, aging resistance, low price and convenient construction, etc., and has a wide market demand. At present, there are many kinds of thermal insulation mortars on the market, and their properties are uneven. Most thermal insulation mortars still have poor crack resistance and are prone to cracking. Contents of the invention [0003] The object of the present invention is to provide a crack-resistant thermal insulation mortar with exce...
