Abstract
The invention provides a thermal insulation bonding mortar with high bonding strength. The thermal insulation bonding mortar is characterized in that the mortar consists of a mixed material and water which have weight ratio of 100:20-100:29, wherein the mixed material consists of the following compositions in portion by weight: 25 to 45 portions of portland cement, 2 to 5 portions of re-dispersible latex powders, 0.1 to 0.4 portion of methyl cellulose ether, 20 to 30 portions of pulverized coal ash, 40 to 45 portions of quartz sand and 0.1 to 0.4 portion of modified polyethylene glycol oxide. The thermal insulation bonding mortar has the advantages that the mortar has low cost, can greatly improve the bonding strength between a thermal insulation material and a wall body in an external thermal insulation system, is environment-friendly, has good performances of fireproofing, thermal insulation and aging resistance, saves energy by 80 percent around compared with the prior mortar, has safe and sanitary construction, convenient transportation, good workability, water resistance, water retention, no sagging and no pollution.
Description
Technical field
The present invention relates to a kind of thermal insulation bonding mortar with high bonding strength, belong to the building energy conservation new material technology field.
Background technology
In recent years, got into since the nineties in last century, China as fundamental state policy, greatly develops the production and the application of novel energy-saving construction material to save energy.A very important measure of building energy conservation is exactly that the building enclosure-body of wall of building is set up insulation energy-saving system, and in any insulation energy-saving system, the use of heat insulation cementing mortar all is necessary.
Building dry-powder function mortar is used widely in China as a kind of novel green material of construction.The difference of dry powder function mortar and traditional mortar is, dry powder function mortar is wiped one's face except building by laying bricks or stones of traditional mortar the function, also has heat insulating, anti-cracking, specific function such as corrosion-resistant; And in use do not need hand mixing; Both saved material, even again, steady quality.
At present, thermal insulation mortar is various in style, but quality also is uneven, and the intensity that has is not high, and cohesive force is poor, and the unit weight that has is bigger than normal, and the water absorbability that has is big, and the cracking hollowing appears in construction back easily, and the heat retaining property that has is poor, or application property is bad, and is uneconomical.
Summary of the invention
The objective of the invention is provides the adhesive mortar that is used for building heat insulation system of a kind of resource-conserving and high bond strength under the prerequisite of comprehensive utilization waste resource flyash.
In order to achieve the above object; Technical scheme of the present invention is a kind of thermal insulation bonding mortar with high bonding strength; It is characterized in that; Obtained with weight ratio 100: 20-29 mixing by compound and water, wherein, said compound is made up of silicate cement 25-45 weight part, redispersible latex powder 2-5 weight part, methyl cellulose ether 0.1-0.4 weight part, flyash 20-30 weight part, silica sand 40-45 weight part and modification polyoxyethylene 0.1-0.4 weight part.
Described silicate cement is the silicate cement of label 42.5.
Described redispersible latex powder is a vinyl acetate-ethylene copolymer.
Described flyash is II level flyash, and fineness requirement is through surplus≤20% behind the 45 μ m square hole sieves.
Adhesive mortar of the present invention has the following advantages:
1, cost is low: one ton of product of every output can consume flyash 200-300 kilogram, and the flyash amount that consumes than any one product design at present all manys more than the double centner, and cost reduces more than 5%;
2,, can improve the cohesive strength between the lagging material and body of wall in the outer heat preservation system greatly because the coordination of redispersible latex powder and modification polyoxyethylene is shared;
3, environmental protection, fire prevention, heat insulation, ageing resistance good, than traditional mortar energy-conservation about 80%;
4, construction safety health, convenient transportation, workability is good, and water-fast, water conservation, sagging not and do not pollute.
