Abstract
The invention relates to a modified plaster wall thermal-insulated material which can replace adhesive cement sand pulp thermal-insulated material, wherein it is characterized in that: said wall comprises base interface agent, thermal-insulated layer, anti-alkali glass fiber mesh cloth or steel mesh, and surface layer; the base interface layer is between the brick and the thermal-insulated layer; the thermal conductivity of said invention is 1/6 of cement one, while it is fireproof with stable volume (the contraction rate is lower than 2/10000 and zero in standard condition) to avoid crack.
Description
Technical field
The present invention relates to a kind of constructional materials and body of wall preparation technology thereof, particularly a kind of modified gypsum heat-preserving wall and preparation method thereof.
Background technology
Existing rubber powder cement mortar heat-preserving wall, the following defective of ubiquity: 1, easy to crack, volatilize gradually along with body of wall moisture, when dry, surface of wall can produce and chap, such body of wall natural thermal insulation poor performance; 2, the high shortcoming of rubber powder cement mortar heat-preserving wall cost, because the market price of rubber powder is relatively more expensive, as the raw material of smearing body of wall, natural cost is just than higher.Be easy to generate like this and chap and weak effect, body of wall that cost is high are unsuitable for the Policy Conditions of the current national parties concerned.
Summary of the invention
It is low, not easy to crack to the purpose of this invention is to provide a kind of good stability, drying shrinkage value that can substitute rubber powder cement mortar heat insulating material, cheap new modified gypsum insulation body of wall and preparation method thereof.
For reaching the technical scheme that the foregoing invention purpose adopted be:
The modified gypsum heat-preserving wall be divided into into: basic unit's interfacial agents, insulation layer, alkali resistant glass fibre open weave cloth or gauze wire cloth, surface layer totally four parts constitute.Basic unit's interfacial agents is alkali resistant glass fibre open weave cloth or gauze wire cloth, surface layer between brick wall body and insulation layer then.
Described basic unit interfacial agents, re-dispersible glue powder 1-20%, building gypsum plaster 60-90%, cellulose ether 0.1-2%, natrium citricum 0.01-0.1%, 1-30% sand is formed.
Described insulation layer, by re-dispersible glue powder 1-20%, building gypsum plaster 70-90%, cellulose ether 0.5-4%, natrium citricum 0.01-0.1%, fire-retardant granular polystyrene 1-20% forms.
The 3rd layer is alkali resistant glass fibre open weave cloth or steel screen layer.
Re-dispersible glue powder 10-40%, building gypsum plaster 10-40%, cellulose ether 0.1-2%, natrium citricum 0.01-0.1%, 20-50% sand or ceramic tile are formed.
It is as follows to prepare ten thousand methods:
A, with re-dispersible glue powder, cellulose ether, natrium citricum adds and carries out premix in a small amount of building gypsum plaster and make masterbatch, mixes building gypsum plaster again and the sand blend packs again;
B, behind the job site with powder, granular polystyrene adds water and stirs;
C, the material of the modified gypsum wall insulating layer that stirs is coated with scrapes on basic unit's interfacial agents;
D, alkali-resistant glass fiber mesh cloth or gauze wire cloth are fixed on the insulation layer;
E, surface layer modified gypsum heat-preserving wall heat insulating material is coated with scrapes on alkaline-resisting glass cloth;
F, last putty, emulsion paint or tile fixing.
The invention has the advantages that: utilize the gelatification of building gypsum plaster, thermal resistance value is low, the advantage of good stability; Re-dispersible glue powder solves its water proofing property difference problem; Fire-retardant granular polystyrene is done filler, reduces weight and has insulation effect simultaneously; Cellulose ether is preserved moisture, and improves workability; Natrium citricum slows down the building gypsum plaster reaction time, is convenient to site operation, increases work efficiency; Dry sand is an aggregate, improves product strength.
Compared significant technical advantage with existing heat insulating material: existing external-wall heat-insulation material belongs to cement based mostly, the ubiquity hollowing, the cracking peeling accumulation of salt in the surface soil, even obscission, tracing it to its cause is: the drying shrinkage value of cement based goods is big (being about 3/1000ths); The different internal stresss that produce of expansion shrinkage factor between insulation layer and the surface layer; Cement mortar is to the corrosion of glass fiber reticular cloth.
And the modified gypsum coefficient of thermal conductivity to be about be the sixth of cement based goods.Can prevent fires and not fire, volume stability (shrinkage value is zero under the standard state less than 2/10000ths) can be avoided cracking effectively.The insulation layer of modified gypsum heat-preserving wall, surface layer are homogeneous material, and adhesion stress adhesive power all is better than the cement based heat insulating products.Gypsum is a neutral material (pH value: 7), can not corrode glass fiber reticular cloth.The modified gypsum incorporation degree is good in addition, operates simple and easyly, and the engineering time is adjustable, and single work efficiency rate is several times as much as other products, and the ash that lands is few, has reduced building costs.
The modified gypsum heat-preserving wall be divided into into: basic unit's interfacial agents, insulation layer, alkali resistant glass fibre open weave cloth or gauze wire cloth, surface layer totally four parts constitute.Basic unit's interfacial agents is alkali resistant glass fibre open weave cloth or gauze wire cloth, surface layer between brick wall body and insulation layer then.
