Glazed hollow bead thermal insulation mortar and preparation process thereof

Abstract

The invention relates to a glazed hollow bead thermal insulation mortar and a preparation process thereof, which are applicable to interior and exterior thermal insulation plastering projects of enclosure walls of multi-storey and high-rise buildings and the like, as well as fire prevention and thermal insulation projects and thermal insulation transformation projects of old buildings. The glazed hollow bead thermal insulation mortar is prepared by the raw materials of ordinary Portland cement, ash calcium powder, sand, lignin, polypropylene staple fiber, silica fume and composite resin rubber powder in parts by weight, and can overcome great hydroscopicity and easy pulverization of expanded perlite, large volume shrinkage during stirring of slurry, and easy emergence of the phenomena of low strength, hollowing, cracking and the like during the late stage of a product, simultaneously make up for defects of flammability of polyphenyl granular organic material, poor fireproof performance, production of harmful gas due to high temperature, low aging resistance and weather resistance, large rebound resilience during construction and the like, and enhance and improve comprehensive performance and construction performance of the thermal insulation mortar.

Description

technical field [0001] The present invention relates to a thermal insulation mortar, in particular to a vitrified bead thermal insulation mortar and its preparation process, which is suitable for reinforced concrete, aerated concrete, blocks, sintered bricks, non-sintered bricks and light-weight concrete of multi-story and high-rise buildings. Internal and external thermal insulation and plastering projects of enclosure walls such as wall materials, as well as fire and thermal insulation projects such as basements, garages, stairs, corridors, fire exits, etc., and are especially suitable for thermal insulation renovation projects of old buildings. Background technique [0002] Insulation mortar refers to a kind of building material used for the construction of insulation layer on the surface of the building. The construction of the insulation layer is generally divided into three layers. The first layer is to apply a layer of adhesive mortar on the leveled wall, which is com...
