Problems solved by technology

The mortar uses ordinary Portland cement as the cementitious material and a new graded expanded closed-cell perlite as the light aggregate. It has the characteristics of low thermal conductivity, low shrinkage, high strength, and good workability. It effectively solves the problem of Inorganic thermal insulation mortar has technical problems such as large water absorption, easy cracking, thermal insulation failure, uneven mixing during preparation, and inorganic light aggregates are easily broken.

Embodiment 1

[0027] One-component inorganic thermal insulation mortar, its raw material components and weight content are as follows: cement 400, fly ash 200, sepiolite fiber 30, gypsum 10, expanded closed-cell perlite 400, redispersible latex powder 10, cellulose ether 2. 1000 parts of water.

[0028] The method for preparing a one-component inorganic thermal insulation mortar includes the following steps: firstly, cement, fly ash, sepiolite fiber, gypsum, redispersible latex powder and cellulose ether are put into a gravity-free mixer according to the required weight ratio. The stirring spindle stirs at the normal speed of 50 rpm, and the high-speed flying knife is started at 1440 rpm. After 6 minutes of stirring, the high-speed flying knife is stopped, and the speed of the stirring spindle is reduced to 30 rpm and then put into the well-measured gradation expansion closed cell Perlite, continue to mix for 2 minutes, the material can be unloaded. Use an open packaging machine to pack into d...

Abstract

The invention relates to single-component inorganic heat-insulating mortar which is prepared from the following components in parts by weight: 400-500 parts of cement, 400-450 parts of expanded closed cell perlite, 100-200 parts of fly ash, 5-10 parts of redispersible emulsion powder, 10-30 parts of sepiolite fiber, 2-3 parts of cellulose ether, 10-20 parts of gypsum and 1000-1200 parts of water. The inorganic heat-insulating mortar has low heat conduction coefficient, good thermal insulation performance, high compressive strength and bonding strength, excellent mechanical performance, good construction workability, simple operation and high construction efficiency; and single-component production is carried out by adopting the process of the invention, the quality is easy to control, and the invention is beneficial to on-site civilized construction.

Description

Technical field [0001] The invention belongs to the technical field of building materials and chemistry, and relates to a building insulation mortar and a preparation method thereof, and more specifically, it is a single-component inorganic insulation mortar. The invention also relates to a preparation method of the single-component inorganic thermal insulation mortar. Background technique [0002] Thermal insulation mortar is an important building energy-saving material. At present, there are many varieties of external wall insulation mortar. Among them, a large part of the thermal insulation mortar is processed by organic polystyrene particles. Although the rubber powder polystyrene particle thermal insulation mortar processed from polyphenyl particles has the advantages of good thermal insulation, there are still many problems: 1. Poor construction workability, poor compatibility with inorganic materials, poor operability of quality control during construction, resulting in ...
