White vitrified bead modified insulation masonry mortar and using method thereof

Abstract

The present invention belongs to the field of building energy-saving materials, and relates to white vitrified bead modified insulation masonry mortar and a using method thereof. The white vitrified bead modified insulation masonry mortar uses vitrified beads to partly replace aggregate, and comprises the fowling components by mass: 47.5-70.5% of a gelled material, 10%-35% of the vitrified beads, 3.6-20% of the aggregate, 0.3%-2% of dispersable emulsion powder, 0.1%-0.3% of hydroxypropyl methyl cellulose ether, 0.1%-1.2% of polypropylene fiber, 0.5%-1% of sepiolite fiber, 0.1%-0.5% of a waterproofing agent and 0.08%-0.3% of mortar king. The white vitrified bead modified insulation masonry mortar has excellent construction performance, good wall body bonding performance, and white color, and in the premise of meeting the basic mechanical properties and durability properties of the bonding mortar, effectively reduces the mortar thermal conductivity coefficient, saves building energy consumption, and is very broad in application development prospect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a white vitrified microbead thermal insulation masonry mortar and a preparation method thereof. Background technique [0002] my country's external wall insulation system mainly uses organic insulation materials. Although this type of thermal insulation material has good thermal insulation performance, it has poor weather resistance, poor volume stability, is not fire-resistant, and is easy to age. Compared with organic insulation materials, inorganic insulation mortar has many advantages. Inorganic thermal insulation mortar, especially vitrified microbead thermal insulation mortar, is a single-component thermal insulation mortar formed by premixing vitrified microbead aggregate with inorganic cementitious materials and organic additives. It has low cost, high strength, and thermal insulation With the advantages of heat insulation, fire prevention, and weather resistance, it c...

AI Technical Summary

Problems solved by technology

However, the surface of polypropylene fiber is smooth and the surface energy is low. When it is mixed with cement-based materials, there are problems of poor fiber dispersion and poor fiber-matrix bonding performance.

Although wood fiber is easier to mix evenly in the vitrified microbead thermal insulation mortar system, it has the disadvantage of retarding

At the same time, as a masonry mortar, vitrified microbead thermal insulation mortar has the problem of repulsion between mechanical properties and thermal insulation properties.
