Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of lightweight plastering gupsum mortar and preparation method thereof.
Background technique
Plastering gupsum is manufactured by national standard " plastering gupsum " GB/T28627-2012, alternative tradition painting stone
A kind of new green environment protection type plastering material of cream and cement base plastering mortar not only has light, heat preservation, heat-insulated, fire resisting, micro-
The characteristics such as expansion, damping, and it is big to efficiently solve traditional cement mortar poor water retention property, drying shrinkage, wall plastering hollowing, crack etc.
Problem.
Land plaster refers to dihydrate gypsum calcined semi-hydrated gypsum, including desulfurized gypsum, ardealite, the natural gypsum etc., takes off
Sulphur gypsum is power plant desulfurization technique bring solid waste.Desulfurized gypsum main component is calcium sulphate dihydrate CaSO4.2H2O,
Content >=93%.With the presence of individual crystalline particle, more averagely its distribution band is very narrow for granular size, and impurity is few, "dead",
Health is not endangered, output is relatively uniform in whole nation distribution.Flyash is the fine ash that catching is got off from the flue gas after coal combustion, powder
Coal ash is the primary solids waste of coal-burning power plant's discharge.Boiler of power plant bottom ash is exactly the coal-powder boilers such as power plant or steam power plant or fluidisation
The waste residue excluded after pool furnace coal combustion from boiler bottom has blocky, graininess and powdery.Bubble slag is added suitable when being ironmaking
Flux (lime, quartz, fluorite etc.) is adjusted what heel row was removed, the melting waste slag formed with water rapid cooling.These are solid
Body waste material is not used effectively, and waste is big, pollutes environment.The present invention is by desulfurized gypsum or the natural gypsum, flyash, boiler
Bottom ash, bubble slag etc. carry out waste utilization, and lightweight plastering gupsum mortar is made, not only turns waste into wealth, but also have effectively played light
The advantages that matter plastering gupsum mortar lightweight, anti-hollowing, cracking resistance are stitched, environmentally protective.And improve architecture quality.
Summary of the invention
Present invention aims at provide a kind of lightweight plastering gupsum mortar and preparation method thereof, which is by taking off
Sulphur gypsum or the natural gypsum, it is flyash, boiler bottom slag, one or two kinds of in bubble slag or three kinds, hydroxypropyl methyl cellulose and
Retarder sugar calcium, citric acid are mixed, the lightweight plastering gupsum mortar have light, good water-retaining property, bonding force big, heat preservation,
The features such as heat-insulated, fire resisting, great advantage are micro-expansibilities after solidification, not only efficiently solve because cement mortar poor water retention property,
Dry after-contraction is big, causes wall plastering hollowing, crack construction quality common fault, while making solid waste is comprehensive to recycle, and protects
Environment has saved resource.Efficiently solve is made solid waste fail to utilize by prior art limitation, pollutes environment, and
The problems such as wasting resource.
A kind of lightweight plastering gupsum mortar of the present invention, the gypsum mortar are by 40-75% desulfurization by weight percentage
Gypsum or the natural gypsum, 24.65-59.1% flyash, boiler bottom slag, one or two kinds of in bubble slag or three kinds, hydroxypropyl methyl
Cellulose and retarder sugar calcium 0.3-0.6% and citric acid 0.05-0.3% are mixed.
A kind of preparation method of lightweight plastering gupsum mortar, follows these steps to carry out:
A, it by boiler of power plant bottom ash, clinker, is crushed, through≤2.5mm sieve screening, it is spare；
B, iron-smelter bubble slag is crushed, through≤2.5mm sieve screening, it is spare；
C, by weight percentage respectively by 40-75% desulfurized gypsum or the natural gypsum, 24.65-59.1% flyash, boiler bottom slag,
It is one or two kinds of or three kinds in bubble slag, hydroxypropyl methyl cellulose and retarder sugar calcium 0.3-0.6% and citric acid 0.05-
0.3%, which is put into blender, is mixed 3-5 minutes to get lightweight plastering gupsum mortar is arrived；
D, obtained lightweight plastering gupsum mortar is packed and stored as finished product.
A kind of lightweight plastering gupsum mortar of the present invention and preparation method thereof, which has the beneficial effect that
The gypsum mortar be by desulfurized gypsum or the natural gypsum, it is flyash, boiler bottom slag, one or two kinds of in bubble slag or three
Kind, hydroxypropyl methyl cellulose and retarder sugar calcium, citric acid are mixed, and are efficiently solved prior art limitation and are not able to achieve
Solid waste Utilizing question, especially do not mention in the prior art and make lightweight plastering gupsum mortar using clinker, but not
It is clearly boiler bottom slag.Contain boiler bottom slag in time, selects 100 mesh clinker below thin after also only screening to clinker
Powder, and measure the particle of biggish 100 mesh or more and block and be not used, still discarded.The present invention overcomes this deficiencies, will
Block carries out broken use, still returns to crusher by the clout after screening and continues to be crushed, realizes solid waste 100%
It utilizes.The lightweight plastering gupsum mortar has the characteristics that light, good water-retaining property, bonding force are big, keep the temperature, heat-insulated, fire resisting, maximum
Advantage is micro-expansibility after solidification, not only efficiently solves because cement mortar poor water retention property, dry after-contraction are big, causes wall plastering
Hollowing, crack construction quality common fault, realize thin-coat plaster technology, make the reduction of plastering construction cost, while keeping solid waste comprehensive
It recycles, protects environment, saved resource, economic benefit and social benefit are obvious.Lightweight plastering gupsum mortar system of the present invention
Standby simple, materials are convenient, and production cost is low, have the characteristics that bulk density is small, over dry intensity is big, heat preservation humidity conditioning performance is good, have wide
Wealthy market prospects.
