Abstract
The present invention relates to a kind of pretreatment of particles technique for packing reducing haydite 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 haydite particles surface, haydite particles is made tentatively to moisten；Third walks：Sulphate aluminium cement is stirred into flowing water slurry body according to match ratio：4th step：By cement slurry be sprayed on haydite particles to completely be wrapped after discharge；5th step：It conserves 6 hours at ambient temperature, after sulphate aluminium cement condenses hardening completely, forms the wrapping layer that uniform, thickness is 1~2mm outside haydite.The strong sulphate aluminium cement shell of a floor height is wrapped up on the haydite surface that the present invention keeps water absorption rate big, and the haydite after package has higher-strength, and the water absorbing properties of particle can be obviously reduced, and water absorption rate is only 0.5% within 1 hour.
Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of pretreatment of particles package reducing haydite water absorption rate
Technology, the heat-insulation wall plate for being mainly used for the assembled architectures such as residential houses, office building make.
Background technology
Haydite wall heat insulation material have many advantages, such as heat insulation property it is good, etc. it is cheap, easy for construction, be China building
The developing direction of energy-saving wall material.
However, haydite has the characteristics that porosity is high, water absorption rate is big, water consumption increases in whipping process, destroys sand
The solidification cycle of slurry so that the mechanical property of mortar substantially reduces, and easily generates hollowing, cracking, seriously affects entire heat preservation system
The thermal property and durability of system.Disadvantages mentioned above limits large-scale popularization application of the haydite heat-insulation wall plate in building field, however
There is presently no relevant solutions.Therefore it is badly in need of being surface-treated haydite particles, realizing reduces water absorption rate, raising
The purpose of grain intensity.
The particle encapsulation technology for researching and developing haydite, porosity is big, shaggy haydite surface wrap up one layer it is fast hard, high-strength
Shell layer significantly reduce its water absorbing properties while improving haydite integral strength, increase substantially assembled haydite heat preservation
The intensity of wallboard improves the effect of building thermal-insulation energy-saving for accelerating the development of China's assembled architecture, have most important theories and
Realistic meaning.
Invention content
The present invention is to provide a kind of drop for the deficiency that porosity rate existing in the prior art is big, water absorption rate is high
The pretreatment of particles technique for packing of low haydite water absorption rate, the haydite made using this technology, it is strong that a floor height has been wrapped up on surface
Sulphate aluminium cement shell layer, have the characteristics that intensity is high, water absorption rate is low, the strong of assembling thermal-insulating wall board can be significantly improved
Degree, suitable for requiring the buildings such as high house, office building heat preservation, heat-insulated, sound insulation.
The specific technical solution of the present invention is as follows：
It is a kind of reduce haydite water absorption rate pretreatment of particles technique for packing, the technology processing procedure in five 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 haydite particles surface, haydite particles is made to be sufficiently humidified so as to；
Third walks：Sulphate aluminium cement is stirred into flowing water slurry body according to match ratio：
4th step：Haydite after moistening is poured into blender to be stirred, aluminium sulfate water is sprayed during stirring
Slurry body controls the thickness of wrapping layer, stir and is sprayed to haydite quilt completely by spraying the amount of sulphate aluminium cement slurry
It discharges after sulphate aluminium cement package；
5th step：It conserves 6 hours at ambient temperature, after sulphate aluminium cement condenses hardening completely, outside haydite
Form 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 haydite surface, the hydrophilic ability of haydite can be improved, improves the bonding with sulphate aluminium cement.
The sulphate aluminium cement is the rapid hardening high-strength sulphate aluminium cement that strength grade is 62.5.
The cement slurry setting time can be controlled within 30 minutes, and intensity reaches 80MPa after hardening, can rapidly exist
It is wrapped to form high-strength shell outside big, the coarse haydite of porosity, significantly reduces water absorption rate, water absorption rate is only within 1 hour
0.5%.Include following substance by mass percentage by match ratio：
The sulphate aluminium cement has good adhesive property with Portland cement, and by this technology, treated
Haydite can significantly improve the compression strength of assembling thermal-insulating wall board.
Compared to the prior art the present invention, has the following advantages that：
(1) haydite particles encapsulation technology provided by the invention is used, it can be rapidly in the pottery that porosity is big, water absorption rate is high
Grain periphery package last layer sulphate aluminium cement shell, compared with before package, the haydite after package has higher cylindrical compress strength
Very low water absorption, to significantly improve the intensity of assembled haydite heat-insulation wall plate；
(2) sulphate aluminium 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.
