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
The present invention relates to a kind of thermal insulation mortar, be specifically related to a kind of environment-friendly insulating mortar, belong to building field.
Background technology
Energy-conserving and environment-protective are one of fundamental state policies of China, and therefore country is advancing the environmental protection and energy saving requirement to buildings, and in order to reach relevant energy conservation standard, buildings generally all will carry out the construction of thermal insulation layer.Traditional lagging material is expansion polyphenyl plate, extruded polystyrene board and polyurathamc etc., although its thermal conductivity is less, excellent thermal insulation performance, but it is as organic insulation material, fire resistance is poor, and in recent years, China there occurs a lot of serious fire caused because of the organic insulation material that ignites, therefore, a lot of area starts to widely popularize inorganic heat insulation mortar.
Electromagnetic pollution is a kind of novel environomental pollution source, along with the progress of society, and the extensive application of electronics, electromagnetic environment is day by day complicated; On the other hand, along with the enhancing with environmental consciousness that improves constantly of living standards of the people, people start more and more to pay close attention to the impact of hertzian wave on environment.
And in order to tackle day by day serious Contamination of Electromagnetic Wave, propose corresponding solution, in thermal insulation mortar, mix a certain amount of absorption agent, absorption process is carried out to hertzian wave, weaken electromagnetic disadvantageous effect.But, prior art for frequency range all at below 18GHz, and its assimilation effect is not mentioned to the hertzian wave of higher frequency.In addition, the absorption agent selected mostly is carbon-based material, such as electrically conductive graphite, carbon black etc., these materials are as absorption agent, and intensity is low, thermal conductivity is high, if add-on is too high, then can reduce the intensity of thermal insulation mortar, weaken the heat insulation effect of thermal insulation mortar, meanwhile, thermal insulation mortar is a kind of light material, comparatively strict restriction is had to dry density, general requirement all will at below 400kg/m3, and absorption agent add-on is too high, will inevitably improve the dry density of thermal insulation mortar.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of insulation thermal insulation mortar of anti-cracking performance excellence, can overcome that thermal insulation mortar ftractures, the common fault such as to flake, and has the function of electromagnetic wave absorption while improving heat-insulating property concurrently.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of environment-friendly insulating mortar, comprises the component of following weight part: silicate cement 40-65 part, heat preserving aggregate 10-20 part, fortifying fibre 5-10 part, redispersable latex powder 5-10 part, filler 10-20 part, light calcined magnesia 1-5 part, diatomite 5-10 part.
Further, described heat preserving aggregate is the mixture of glass bead, pearlstone and carbon aerogels.
Further, in described heat preserving aggregate glass bead, pearlstone and carbon aerogels weight ratio be 1-3:1-5:1.
Further, described fortifying fibre is the mixture of polypropylene fibre, ether of cellulose, hydroxyethyl ether cellulose, Vltra tears.
Further, in described fortifying fibre, the weight ratio of polypropylene fibre, ether of cellulose, hydroxyethyl ether cellulose, Vltra tears is 1:1:1:1.
Further, the mixture that described filler is brucite powder, mica powder, kaolin, ground dolomite mix with arbitrary proportion.
Thermal insulation mortar of the present invention, during use, conveniently thermal insulation mortar collocation method situ configuration uses.
Thermal insulation mortar resistance to cleavage of the present invention is excellent, can overcome that thermal insulation mortar ftractures, the common fault such as to flake, and cohesive strength is high, strong adhesion, has the performances such as good heat insulation property, weathering resistance, fire-proof and water-proof, frost resistance; The volume stability of thermal insulation mortar is good, produces volume microdilatancy, does not ftracture, not hollowing during setting and harden, and water tolerance is strong, anti-aging, long service life; And thermal insulation mortar of the present invention is nontoxic, tasteless, "dead", harmless, free from environmental pollution, there is the advantage of energy-conserving and environment-protective, absorption of electromagnetic radiation.
