Abstract
The invention discloses a kind of light-weight environment-friendly type thermal insulation mortar, it is grouped into by the one-tenth of following parts by weight: Portland cement 120～180 parts, foam glass powder 15～20 parts, foam grain 1.5～2 parts, hydroxyethyl cellulose 0.1～0.5 part, redispersable latex powder 2～4 parts, wollastonite in powder 3～5 parts.The foam glass powder that the present invention selects is made by discarding cullet, density≤200Kg/m3, foam grain is formed by waste foam is broken, density≤20Kg/m3.Thermal insulation mortar heat conductivity of the present invention is low, cracking resistance, construction is simple, low cost, unit weight light, effectively reduces the deadweight of building and the burden to given tensile load, makes full use of trade waste, solve problem of environmental pollution, environmental protection and energy saving.
Description
Technical field
The invention belongs to building wall mortar technical field, be specifically related to a kind of light-weight environment-friendly type insulation sand
Slurry.
Background technology
Thermal insulation mortar is a kind of construction material for constructing building insulating layer, master the most on the market
There are two kinds: inorganic heat insulation mortar and organic heat-insulating mortar (adhesive polystyrene granule heat-insulating mortar).Organic guarantor
Temperature mortar cost is on the low side, but non-refractory, inflammable, has the trend gradually replaced by inorganic heat insulation mortar.
Inorganic heat insulation mortar is as aggregate with various light materials (glass bead or expanded perlite), with cement
For gellant, admixing what some property-modifying additives were made, its safety is higher, and fire retardant performance is good,
But cost is higher, cause Engineering Overall cost increase.
The present invention uses foam glass powder and foam grain as aggregate.Foam glass be by cullet,
The materials such as foaming agent are through pulverizing after mixing, then make through the operation such as high temperature melting, foaming, close
Degree≤200Kg/m3, inner void enriches, and A level does not fire the life-span same with building, is a kind of superior performance
Lightweight, be incubated, absorb sound, fire-retardant, barrier material.Additionally, the production of foam glass is waste solid material
Material recycling, is protection environment the example obtaining economic interests.
Foam plastics is a kind of waste packaging materials being difficult to natural degradation being present in a large number in life, its
Density is little, water absorption rate is low, good hygroscopicity, chemical stability are strong, thermal conductivity is low, has good heat insulation guarantor
Warm nature energy.It is filled in inside mortar with foam plastics as aggregate, can effectively reduce mortar unit weight, improve
Mortar heat-insulating property, cracking resistance and temperature shrinkage strain property.
Summary of the invention
The present invention is big with regard to general inorganic thermal insulation mortar unit weight, cost is high causes greatly environment with solid waste
The fact that amount is polluted, disclosing a kind of light-weight environment-friendly type thermal insulation mortar, this mortar is by following parts by weight
One-tenth is grouped into: Portland cement 120～180 parts, foam glass powder 15～20 parts, foam plastics
Granule 1.5～2 parts, hydroxyethyl cellulose 0.1～0.5 part, redispersable latex powder 2～4 parts, silicon ash
Stone powder 3～5 parts.
Described foam glass powder footpath is between 0.5～3mm.
Described foam grain is polystyrene foam grain or polyethylene foams granule.
Described foam grain particle diameter is≤5mm.
Described redispersable latex powder is acrylic compounds latex powder or ethylene one Vinyl acetate copolymer latex powder.
The preparation method of light-weight environment-friendly type thermal insulation mortar of the present invention is as follows:
(1) used foamed plastics is crushed to particle diameter≤5mm；
(2) foam glass powder both can be selected for commercially available, it is possible to by the pulverizing of waste foam glass edge corner material
Become；
(3) a certain amount of Portland cement, foam glass powder, foam plastics are weighed according to the above ratio
Granule, hydroxyethyl cellulose, redispersable latex powder, wollastonite in powder, put into machine mixer, mixing
To uniform state, obtain described product.
There is advantages that
(1) present invention uses foam glass and two kinds of light materials of foam plastics to be aggregate, prepared product
Not only there is good insulation anti-flaming function, heat conductivity≤0.25W/m K, and unit weight be light,
Loose bulk density≤750Kg/m3, effectively reduce the deadweight of building and the burden to given tensile load；
(2) two kinds of aggregates of the present invention all can be selected for the garbage that has been previously used (foam glass using
Cheng Zhonghui produces substantial amounts of discarded leftover pieces), so while saving mortar cost, also solve environment
Pollution problem, kills two birds with one stone, environmental protection and energy saving；
(3) present invention selects hydroxyethyl cellulose and the redispersable latex powder of proper ratio, can make foam
Plastic grain and portland cement, foam glass powder are dispersed, and after adding water, product viscosity is suitable, viscous
Knot ability is strong；
(4) product of the present invention is pollution-free, nontoxic, anti-cracking performance strong, and burning grade reaches A2 level not
Combustion, service life is long.
