Problems solved by technology

Electromagnetic wave radiation not only affects people's health, but also causes information leakage of electronic equipment in security and confidentiality systems, important command systems, diplomatic departments, etc.
Insulation mortar is neither an insulator nor a good conductor, and its resistance is generally 10 4 ~10 7 Ω·m, poor shielding effect on electromagnetic waves

Abstract

The invention discloses a technology for preparing zeolite-containing inorganic insulation mortar. The technology is characterized by comprising the following steps of: adding zeolite, modified lightweight aggregate, fly ash, sepiolite, conductive fiber, hydroxymethyl cellulose, organic water repellent and re-dispersible latex powder into a gel material, stirring uniformly, and thus obtaining the dry powder inorganic insulation mortar, wherein based on the mass of the gel material, the inorganic insulation mortar contains 1 to 10 percent of zeolite, 100 to 300 percent of modified lightweight aggregate, 20 to 100 percent of fly ash, 1 to 20 percent of sepiolite, 0.01 to 5 percent of fiber, 0.5 to 5 percent of hydroxymethyl cellulose, 0.5 to 5 percent of organic water repellent and 0.5 to 5 percent of re-dispersible latex powder.

Description

technical field [0001] The invention relates to a preparation method of high-strength light-weight thermal insulation mortar capable of absorbing radon gas, having electromagnetic shielding ability and alkali-free aggregate reaction. Background technique [0002] With the rapid and steady advancement of building energy-saving work, inorganic thermal insulation mortar has developed rapidly, and its engineering application volume has continued to increase, with broad application prospects. The main raw materials of inorganic thermal insulation mortar are cementitious material, lightweight aggregate and additives. [0003] (1) Research on clinker-free cementitious materials [0004] At present, Portland cement is often used as the cementitious material of thermal insulation mortar. Portland cement mainly uses limestone, clay and sandstone as raw materials. It is calcined at high temperature to obtain cement clinker. After adding a certain amount of admixture materials and gyp...
