Abstract

The invention provides heat preservation mortar, which comprises the bending ratios of components in a binding material and the bending ratios between the binding material and water. The binding material comprises the following components in weight percentage: 30 to 50 percent of vitrified micro bubble, 5 to 20 percent of ceramic sand, 1 to 5 percent of fly ash, 35 to 50 percent of ordinary Portland cement, 3 to 5 percent of wood fiber, 1 to 2 percent of hydroxypropyl emthylcellulose, 2 to 5 percent of re-dispersible emulsion powder and 0.4 to 0.5 percent of water reducing agent; and the weight ratio between the binding material and water is between 1:0.6 and 0.5. The light weight heat preservation mortar has the advantages of good binding property, good water-retention property, good anti-cracking property and good heat preservation and heat insulation property, and is applied to the laying and the plastering of wall materials; particularly the laying and plastering of steam-pressure air-entrained concrete bricks, the heat preservation and energy conservation effects are obvious.

Description

Light heat-insulation mortar
Technical field
The present invention relates to a kind of light heat-insulation mortar, particularly relate to a kind of insulation, water conservation, good the building by laying bricks or stones and motar of resistance to cleavage.
Background technology
At present, the thermal insulation mortar that uses in the wall construction is of a great variety, and spread in performance is uneven, and wherein common has: EPS granule heat-insulating mortar, swelling perlite heat-insulating mortar, kervit microbead insulated sand slurry.Though wherein the EPS granule heat-insulating mortar has advantages such as thermal and insulating performance is good, erosion resistance is better; But because EPS is organic light material, cause the workability of mortar poor, difficulty of construction is big; Cohesive force is less; Fire resistance is poor, and particularly organic materials can discharge objectionable impurities, should not promote the use of on a large scale; Swelling perlite heat-insulating mortar is owing to the open-celled structure of pearlstone, and its slit by the cement filling, reduces its heat-insulating property in the mortar whipping process greatly; In addition, this kind mortar water-intake rate is big, the freeze-thaw-ability, and mortar is easily dehydration and produce shrinkage crack in the setting and harden process; The thermal insulation mortar heat-insulating property of glass bead is good, but because little, the intensity difference of particle diameter of glass bead causes the intensity of mortar lower, is difficult to be applied in the engineering project that masonry strength is had relatively high expectations.
Since banning use of solid clay brick; Autoclave aerated concrete building block is that domestic wideling popularize used one of materials for wall that substitutes solid clay brick; Unit weight is light because it has, insulation, fire prevention, sound-absorbing, anti-seismic performance are good, and in-situ processing is convenient, is easy to construction and uses industrial residue in a large number; Energy-conservation characteristics such as save land are built the welcome of each side deeply.It is reported that autoclave aerated concrete building block is present domestic unique a kind of single materials for wall that can satisfy building energy conservation 65% design requirements at severe cold area.But, because this walling has its water-intake rate big, use conventional cement mortar build by laying bricks or stones and plaster occur hollowing easily, ftracture, peel off, phenomenons such as latticed black surround appear in interior metope.Therefore; Have only the mortar joint of increasing thermal resistance, improve insulation, the water retention property of mortar, make it to be complementary with the thermal resistance of building material; Could reduce the mortar joint correction factor, stop the influence to wall insulation performance such as heat bridge phenomenon, improve the thermal and insulating performance of peripheral structure on the whole.
Summary of the invention
The object of the present invention is to provide a kind of have good heat preservation performance, good water-retaining property, the light heat-insulation mortar of high, anti-aging, the fire prevention of hollowing cracking, intensity and corrosion resistance nature.The present invention is applicable to that the materials for wall that its thermal conductivity is complementary with it builds by laying bricks or stones and plastering construction.
In order to achieve the above object, the present invention adopts following technical scheme: its composition and proportioning (by weight percentage) are: glass bead: pottery sand: flyash: ordinary Portland cement: xylon: Vltra tears: redispersible latex powder: water reducer=30～50%:5～20%:1～5%:35～50%:3～5%:1～2%:2～5%:0.4～0.5%.
Wherein: glass bead plays insulation, sound-absorbing, fire prevention, reduction unit weight and improves grating; The particle diameter of pottery sand is 0.3～0.5mm, in thermal insulation mortar, plays aggregate, improves mortar strength; Flyash improves the workability of mortar, reduces cement consumption, reduces the mortar cost; Vltra tears plays the thickening water conservation; Redispersible latex powder forms one deck liquid film in mortar, improve the water retention property of mortar, thereby guaranteed fully aquation of mortar, guarantees mortar strength.
Above-mentioned thermal insulation mortar preparation method is following: each component of weighing in proportion, and successively glass bead, pottery sand, flyash, ordinary Portland cement, xylon, Vltra tears, redispersible latex powder, water reducer are poured in the drum mixer and mixed; Adding water (in the ratio of matrix material: water=1:0.6～0.65) stirs and promptly obtains light heat-insulation mortar of the present invention.
The advantage of thermal insulation mortar of the present invention is: 1, mortar strength is high, viscosifying power is strong; 2, slurry density is low, and thermal conductivity is low, and the mortar joint correction factor is little, good heat insulating; 3, good water-retaining property has been controlled because of the hollowing that the mortar dehydration causes, the generation of cracking phenomena to greatest extent.
Embodiment
Embodiment 1: a kind of efficient light heat-insulation mortar, its set of dispense ratio is: glass bead: pottery sand: flyash: ordinary Portland cement: xylon: Vltra tears: redispersible latex powder: water reducer=35kg:15kg:3kg:40kg:3kg:1kg:2kg:0.4kg.
The preparation method of above-mentioned light heat-insulation mortar is following; Each component of weighing is according to the above ratio earlier poured glass bead, pottery sand, flyash, ordinary Portland cement, xylon, Vltra tears, redispersible latex powder, water reducer in the drum mixer into and is mixed; Adding water 60kg stirs and promptly obtains light heat-insulation mortar of the present invention.
Embodiment 2: a kind of efficient light heat-insulation mortar, its set of dispense than (weight ratio) is: glass bead: pottery sand: flyash: ordinary Portland cement: xylon: Vltra tears: redispersible latex powder: water reducer=30kg:17kg:5kg:40kg:3kg:1kg:3kg:0.5kg.
The preparation method of above-mentioned light heat-insulation mortar is following: each component of weighing according to the above ratio, and earlier glass bead, pottery sand, flyash, ordinary Portland cement, xylon, Vltra tears, redispersible latex powder, water reducer are poured in the drum mixer and mixed; Adding water 60kg stirs and promptly obtains light heat-insulation mortar of the present invention.
Employed cement is normal silicate P.O42.5 cement in the foregoing description.
