Abstract

The invention discloses vitrified microbead thermal insulation mortar and a preparation method thereof. The thermal insulation mortar is prepared from the following raw materials: portland slag cement, lime paste, river sand, vitrified microbeads, sugar calcium, calcium carbonate, white latex, modified attapulgite clay powder, sodium lignin sulfonate, barium stearate, polyester fibers, hydroxypropyl methyl cellulose, polyvinyl alcohol, an organosilicon waterproofing agent and water. The preparation method comprises the following steps: firstly mixing the raw materials such as the vitrified microbeads and sugar calcium, and uniformly stirring, so that slurry A is obtained; then mixing the raw materials such as sodium lignin sulfonate, and uniformly stirring, so that slurry B is obtained; and finally conveying the portland slag cement, the lime paste and the river sand to a mortar stirring machine, and sequentially adding the slurry B and the slurry A, so that the vitrified microbead thermal insulation mortar finished product is obtained. The thermal insulation mortar disclosed by the invention has the advantages that tension and compression strengths and thermal insulation and sound insulation performances are further enhanced compared with the national standard and existing thermal insulation mortar, so that the problems of empty drums, cracks and drops are hardly caused when the mortar disclosed by the invention is applied to a wall body, and durability and practicability of the mortar are improved.

Description

technical field [0001] The invention relates to the field of thermal insulation mortar, in particular to vitrified microbead thermal insulation mortar and a preparation method thereof. Background technique [0002] Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is mainly used to construct building surface insulation As a kind of building material, it has the characteristics of energy saving and waste utilization, thermal insulation, aging resistance, low price and convenient construction, etc., and has a wide market demand. Among them, thermal insulation mortar using vitrified microbeads as raw material is widely used and has superior performance, and vitrified microbeads are a new type of environmentally friendly inorganic lightweight thermal insulation material. It also has the advantages of non-combustibility, high s...
