Abstract

The invention provides heat preservation mortar, which comprises the bending ratios of components in a binding material and the bending ratios between the binding material and water. The binding material comprises the following components in weight percentage: 30 to 50 percent of vitrified micro bubble, 5 to 20 percent of ceramic sand, 1 to 5 percent of fly ash, 35 to 50 percent of ordinary Portland cement, 3 to 5 percent of wood fiber, 1 to 2 percent of hydroxypropyl emthylcellulose, 2 to 5 percent of re-dispersible emulsion powder and 0.4 to 0.5 percent of water reducing agent; and the weight ratio between the binding material and water is between 1:0.6 and 0.5. The light weight heat preservation mortar has the advantages of good binding property, good water-retention property, good anti-cracking property and good heat preservation and heat insulation property, and is applied to the laying and the plastering of wall materials; particularly the laying and plastering of steam-pressure air-entrained concrete bricks, the heat preservation and energy conservation effects are obvious.

Description

technical field [0001] The invention relates to a light-weight thermal insulation mortar, in particular to a masonry and plastering mortar with good thermal insulation, water retention and crack resistance. Background technique [0002] At present, there are many kinds of thermal insulation mortars used in wall construction, and their properties are uneven. Among them, the common ones are: EPS particle thermal insulation mortar, expanded perlite thermal insulation mortar, and vitrified microbead thermal insulation mortar. Among them, EPS granule thermal insulation mortar has the advantages of good thermal insulation performance and good corrosion resistance, but because EPS is an organic lightweight material, the mortar has poor workability, difficult construction, small adhesive force, and poor fireproof performance. , especially organic materials will release harmful substances, so it is not suitable to be widely used; due to the open-pore structure of expanded perlite, th...
