Environment-friendly thermal insulation mortar

Abstract

The invention discloses an environment-friendly thermal insulation mortar comprising the following components in parts by weight: 40-65 parts of Portland cement, 10-20 parts of thermal insulation aggregate, 5-10 parts of reinforced fibers, 5-10 parts of redispersible latex powder, 10-20 parts of filler, 1-5 parts of light calcined magnesia and 5-10 parts of kieselguhr. The environment-friendly thermal insulation mortar has excellent cracking resistance, high bonding strength, strong adhesive force and good thermal insulation heat insulation property, weather resistance, fire and water resistance and freezing resistance. By utilizing the environment-friendly thermal insulation mortar, such common problems of the thermal insulation mortar as cracking and flaking are overcome. The thermal insulation mortar is good in volume stability, generates volume microdilatancy during setting and hardening, does not crack or hollow and is strong in water resistance and ageing resistance and long in service life. The environment-friendly thermal insulation mortar is non-toxic, odorless, non-radioactive and harmless to a human body. By utilizing the environment-friendly thermal insulation mortar, the environment can not be polluted, energy is saved, the environment is protected, and electromagnetic radiation is absorbed.

Description

technical field [0001] The invention relates to a thermal insulation mortar, in particular to an environmental protection thermal insulation mortar, which belongs to the construction field. Background technique [0002] Energy saving and environmental protection is one of the basic national policies of our country. Therefore, the country is promoting environmental protection and energy saving requirements for buildings. In order to meet the relevant energy saving standards, buildings generally need to be constructed with insulation layers. The traditional thermal insulation materials are expanded polystyrene board, extruded polystyrene board and foamed polyurethane, etc. Although their thermal conductivity is small and their thermal insulation performance is excellent, as an organic thermal insulation material, their fire performance is poor. In recent years, my country has experienced There have been many serious fires caused by the ignition of organic thermal insulation mat...

AI Technical Summary

Problems solved by technology

However, the frequency bands targeted by the existing technologies are all below 18GHz, and the absorption effect of higher frequency electromagnetic waves is not mentioned

In addition, most of the absorbents used are carbon-based materials, such as conductive graphite, carbon black, etc. As absorbents, these materials have low strength and high thermal conductivity. At the same time, thermal insulation mortar is a light material, which has strict restrictions on dry density. The general requirement should be below 400kg / m3. If the amount of absorbent added is too high, it will inevitably increase the dry density of thermal insulation mortar.
