Abstract

The invention discloses thermal insulation mortar and a production method thereof and relates to the technical field of building mortar. The thermal insulation mortar is produced from expanded perlite, cement, river sand, coal ash, ethylene propylene rubber particles, glass fibers, modified seaweed and an anti-cracking agent, wherein the anti-cracking agent is formed by mixing hydrogenated castor oil, calcium sulphoaluminate and epoxy resin. The thermal insulation mortar can carry out thermal insulation for a long time and is difficult to crack, high in bonding strength with a basement layer, and hollowing is hardly caused; meanwhile, tensile strength and abrasion resistance can be obviously improved, so that the thermal insulation mortar is smoother, has strong adhesive force with a base material and hardly falls off.

Description

technical field [0001] The invention relates to the technical field of building mortar, in particular to a thermal insulation mortar and a manufacturing method thereof. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various lightweight materials as aggregates, cement as cementitious material, mixed with some modified additives, and mixed by the production enterprise; among them, light aggregates are mostly For expanded perlite. Expanded perlite thermal insulation mortar is made of high-quality acidic volcanic glass rock, which is crushed, dried, put into a high-temperature roasting furnace, and expanded instantaneously. It can be used as loose-fill thermal insulation materials for buildings and thermal equipment; cement, water glass, asphalt, resin, etc. can be used as cementing materials to make various shapes of thermal insulation products, such as plate tubes. [0003] Expanded perlite has a wide range of applications ...
