Description
Technical field
The present invention relates to the production technology category of a kind of reinforced steel bar rust preventing coating, specifically, relate to a kind of steam pressure and add
The gas concrete slab preparation method of reinforced steel bar rust preventing coating.
Background technology
Steam-pressing aero-concrete is a kind of New Building Materials that last century, the '30s grew up, and generally comprises steam pressure
Air-entrained concrete building block, autoclaved aerated concrete slab.Wherein, autoclaved aerated concrete slab is siliceous with cement, Calx, silica sand etc.
Material is that primary raw material adds the varying number a kind of green ring through antiseptic reinforced mesh further according to structural requirement configuration
Protecting construction material, it forms through High Temperature High Pressure, steam curing, has the property such as good fire-resistant, fire prevention, sound insulation, heat insulation, insulation
Energy.Owing to autoclaved aerated concrete slab is the construction material of a kind of lightweight, porous, good permeability, the oxygen in air, titanium dioxide
Carbon and moisture etc. easily contact with rebar surface in sheet material through protective layer, make reinforcing bars rusting.Therefore, add in order to ensure steam pressure
Gas concrete slab produce and life-time service during reinforcing bar will not corrosion, need to be at rebar surface applying preventive by dipping coating.
Produce at present the reinforced steel bar rust preventing coating that the factory of autoclaved aerated concrete slab uses mainly have latex lime sand coating,
Latex cement sand coatings etc., the rustless property of these kind coating is good, meets GB15762-1995 and JC/855-1999 standard
The requirement of middle regulation, but generally there is the problem that reinforcing bar adhesion strength is relatively low, thus have impact on combining of autoclaved aerated concrete slab
Close quality and service life.
Summary of the invention
Present invention aim to provide one can dramatically increase reinforcing bar adhesion strength, raising autoclaved aerated concrete slab is combined
Close quality and the reinforced steel bar rust preventing coating in service life, the preparation side of a kind of autoclaved aerated concrete slab reinforced steel bar rust preventing coating
Method.
The preparation method of a kind of autoclaved aerated concrete slab reinforced steel bar rust preventing coating realizing the present invention is:
One, raw material selection and preparation are first carried out:
Viscosifier: by polyanion cellulose, calcined soda for industry, water respectively with the ratio of weight ratio 4%: 2%: 94% successively
Adding agitator tank, start stirring, dissolving into water white viscous shape liquid completely to polyanion cellulose；
Emulsion: NPE is weighed by weight 1: 2 with water, stirs stand-by；
Sand powder: with grinding machine, silica sand is worn into the dry sand powder that specific surface area is 4000, store stand-by；
Carboxylic styrene butadiene latex: solid content 50% ± 2%；
Cement: PO42.5 cement；
Emulsified asphalt: the emulsified asphalt of solid content >=30%.
Two, various raw materials are selected and after preparation, prepare by following weight (%):
Three, after proportioning raw materials is selected, its preparation process is:
(1) carboxylic styrene butadiene latex, cement, emulsified asphalt and emulsion are sequentially added in blender, and the stirring 1-2 that starts shooting
Minute；
(2) add sand powder under agitation, stir 2-3 minute；
(3) add viscosifier, after stirring 3-5 minute, just prepare the autoclaved aerated concrete slab reinforced steel bar rust preventing of the present invention
Coating, its fluidity is in the 20-25 second.
The autoclaved aerated concrete slab of present invention reinforced steel bar rust preventing coating, significantly improves the rust-preventing characteristic of reinforcing bar in sheet material
Can, solve the problem that between antirust coat and steam-pressing aero-concrete, reinforcing bar adhesion strength is relatively low simultaneously, improve steam pressurized mixed
Concrete board comprehensive quality and service life, comparative test result shows, reinforcing bar adhesion strength is brought up to 1.23MPa by 1.05MPa.
The autoclaved aerated concrete slab reinforced steel bar rust preventing coating of the present invention has the production Technology of uniqueness, superior property
Can, multi items autoclaved aerated concrete slab production requirement can be met, there is the advantages such as low toxicity, environmental pollution are few, through surveying simultaneously
Determine the requirement that indices all reaches or is better than in GB15762-1995 and JC/855-1999 standard regulation, dependable performance.This steel
Muscle antirusting paint is water-dispersion type, steady quality, and preparing process is simple, is suitable to craft and mechanical work, additionally its transport, guarantor
Pipe, use are conveniently, safely, stronger to the process conditions adaptability of steam-pressing aero-concrete.
