The present invention relates to a kind of reduction heat-insulation wall plate technique for packing of expanded perlite water absorption rate, include the following steps：The first step：2 parts of surfactants and 100 parts of water are uniformly mixed into the mixture of surfactant and water；Second step：The mixture of surfactant and water is sprayed on expanded perlite granule surface, expanded perlite granule is made tentatively to moisten；Third walks：Portland cement is stirred into flowing water slurry body according to match ratio：4th step：By cement slurry be sprayed on expanded perlite granule to completely be wrapped after discharge；5th step：It conserves 6 hours at ambient temperature, after portland cement condenses hardening completely, forms the wrapping layer that uniform, thickness is 1~2mm outside expanded perlite.The strong portland cement shell of a floor height is wrapped up on the expanded perlite surface that the present invention keeps water absorption rate big, and the expanded perlite after package has higher-strength, and the water absorbing properties of particle can be obviously reduced, and water absorption rate is only 1.8% within 1 hour.
Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of reduction heat-insulation wall plate expanded perlite water absorption rate
Technique for packing, be mainly used for the assembled architectures such as residential houses, office building heat-insulation wall plate make.
Background technology
Expanded perlite wall heat insulation material have many advantages, such as heat insulation property it is good, etc. it is cheap, easy for construction, be me
The developing direction of state's building energy conservation materials for wall.
However, there is following problem in use in expanded perlite：First, porosity is high, water absorption rate is big so that sand
The water requirement of slurry increases, and destroys the solidification cycle of mortar so that the mechanical property of mortar substantially reduces, easily generate hollowing,
Cracking, seriously affects the thermal property and durability of entire heat-insulation system；Two, the irregular shape with batting shape, is easy in sand
Resistance is generated in slurry whipping process, workability is very poor；Three, granule strength is low, itself has preferable thermal property, but stir in mortar
It is easily broken during mixing, can largely reduce its thermal property.Above-mentioned deficiency limits expanded perlite thermal-nsulation wallboard and exists
The large-scale popularization application of building field, however there is presently no relevant solutions.Therefore it is badly in need of to expanded perlite granule
It is surface-treated, realizes the purpose for reducing water absorption rate, improving granule strength.
The pretreatment technique for packing for researching and developing expanded perlite, porosity is big, shaggy expanded perlite surface is wrapped
Wrap up in one layer of fast hard, high-strength shell layer significantly reduces its water absorbing properties, greatly while improving expanded perlite integral strength
Amplitude improves the intensity of assembled expanded perlite thermal-nsulation wallboard, for accelerating the development of China's assembled architecture, improves building
The effect of heat preservation energy-saving has most important theories and realistic meaning.
Invention content
The present invention is big for expanded perlite porosity existing in the prior art, rough surface, resistance to compression after wallboard is made
The low deficiency of intensity is to provide a kind of technique for packing reducing heat-insulation wall plate expanded perlite water absorption rate, using this technology
The strong portland cement shell layer of a floor height has been wrapped up on the expanded perlite made, surface, has intensity height, water absorption rate low
The characteristics of, the intensity of assembling thermal-insulating wall board can be significantly improved, suitable for requiring high house to heat preservation, heat-insulated, sound insulation, doing
In the buildings such as public building.
The specific technical solution of the present invention is as follows：
A kind of technique for packing reducing heat-insulation wall plate expanded perlite water absorption rate, the technology divide five in processing procedure
Step：
The first step：2 parts of surfactants and 100 parts of water are uniformly mixed into the mixture of surfactant and water；
Second step：The mixture of surfactant and water is sprayed on expanded perlite granule surface, makes expanded perlite
Particle is sufficiently humidified so as to；
Third walks：Portland cement is stirred into flowing water slurry body according to match ratio：
4th step：Expanded perlite after moistening is poured into blender to be stirred, sprays silicic acid during stirring
Salt cement slurry controls the thickness of wrapping layer, stir and is sprayed to expanded pearlite by spraying the amount of Portland cement paste
Rock discharges after being wrapped up completely by portland cement；
5th step：It conserves 6 hours at ambient temperature, after portland cement condenses hardening completely, in expanded perlite
Outside forms the wrapping layer that uniform, thickness is 1~2mm.
Contain carboxylic acid, sulfonic acid, sulfuric acid, amino or amido polar hydrophilic group in the molecular structure of the surfactant,
After being mixed with water and moistening expanded perlite surface, the hydrophilic ability of expanded perlite, improvement and portland cement can be improved
Bonding.
The portland cement is the portland cement that strength grade is 62.5；
The cement slurry setting time, intensity reached 80MPa after hardening within 50 minutes, had with cement-based material good
Good adhesive property has good adhesive property with cement-based material, can be rapidly big, shaggy swollen in porosity
It is wrapped to form high-strength shell outside swollen perlite, is substantially reduced water absorption rate, water absorption rate is only 2% within 1 hour.Match ratio presses quality
Percentages include following substance：
Compared to the prior art the present invention, has the following advantages that：
(1) technique for packing is pre-processed using expanded perlite provided by the invention, it can be rapidly porosity be big, surface
Coarse expanded perlite periphery superscribes a layer silicate cement shell, compared with before package, the expanded perlite after package
With higher cylindrical compress strength and very low water absorption, to significantly improve the intensity of assembled expanded perlite thermal-nsulation wallboard；
(2) portland cement used in the present invention is conventional building material, and raw material are easy to get, and cheap；
(3) present invention's is technically simple easy, fully utilizes a large amount of silicon ashes, flyash equal industrial residue, also has green
The characteristics of colour circle is protected.
Specific implementation mode
A kind of technique for packing reducing heat-insulation wall plate expanded perlite water absorption rate, including five steps：
The first step：2 parts of surfactants and 100 parts of water are uniformly mixed into the mixture of surfactant and water；
