Insulation system with polycrystalline anti-cracking and waterproofing mortar

Abstract

The invention discloses an insulation system with polycrystalline anti-cracking and waterproofing mortar, which belongs to the technical field of the building material. The insulation system comprises interface mortar, insulation mortar and waterproofing mortar, wherein the waterproofing mortar comprises the following components: cement, sand, redispersable latex powder, hydroxypropyl-methyl cellulose ether, inorganic water reducing agent, organosilicon waterproofing agent, sodium silicate and inorganic retarder. Compared with the prior art, the invention has the following advantages of: 1, solving the problem that the bonding strength of the inorganic cementitious material for penetration is not sufficient, and significantly improving the bonding strength and the compressive strength of the whole insulation system; 2, improving the construction property of the material and the insulation effect of the system; 3, improving the construction property and enhancing the long-term strength of the product; 4, improving the waterproofing function of the system, and changing the rigidity of various kinds of polycrystalline mortar into softness, thereby improving the impact resistance, bending resistance, tensile strength, shrinkage resistance and other strain capacities of the insulation system; and 5. improving the bending resistance and the tensile strength of the material and the physical anti-cracking performance of the system.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and specifically relates to a thermal insulation system with polycrystalline crack-resistant and waterproof mortar, which is mainly used for internal and external energy-saving and thermal insulation of walls or roofs of building enclosure structures. Background technique

[0002] At present, domestic and foreign building wall insulation generally adopts plate or component thermal insulation materials, which are expensive, difficult in construction technology, and poor in impact resistance, but have good thermal insulation effects and are suitable for cold regions; there is another thermal insulation material, namely Rubber powder polystyrene particle external wall thermal insulation system, the thermal insulation system is composed of interface layer, thermal insulation layer, anti-crack protective layer, which plays the role of thermal insulation and protection. In the prior art, the...
