Abstract
The new-type paint for external wall is made of acrylic emulsion as cementing material and cheaper natural ore as aggregate through stirring at a temp. over 5 deg.C. Said acrylic emulsion contains less benzenemethanol, glycol, sodium benzoate and polyvinyl butyral and said natural ore must have gay lusture, hard quality, less earth content and granularity of 30-200 meshes. It features no decolouring and low cost.
Description
The present invention relates to a kind of building material product, the preparation method of exterior wall coating material promptly for building.
The exterior wall coating material that present China uses traditionally has chlorinated polyvinyl chloride, polyvinyl alcohol condensation butyraldehyde etc., seems that in decoration of exterior wall texture is flat, easily fades, and durability is undesirable.Therefore many buildings adopt washing stone, ceramic mosaic, mosaic etc.Also have the acrylic emulsion of employing to make sizing material, use the exterior wall coating material of making aggregate through the colorful quartz sands of oversintering, this painting color is bright-coloured, and third dimension is strong.But because quartz sand need be in roasting furnace under 800 ℃ the temperature, could use after adding various pigment and sintering adjuvant,, be difficult to popularization so improved the cost of this coating greatly.
The objective of the invention is to seek a kind of aggregate and replace preparation method through the building external paint of the colorful quartz sands of oversintering with cheapness.
The present invention is achieved in that the sizing material based on acrylic acid is an aggregate with the natural crystal with certain grating, with 3: 10 ratio, stirs, mixes under the normal temperature more than 5 ℃.
The composition of sizing material is (weight ratio):
Acrylic emulsion 100-105
Phenmethylol 3-4
Ethylene glycol 2-3
Sodium Benzoate 0.1-0.5
Polyvinyl butyral 5-8
During the preparation sizing material, earlier acrylic emulsion is stirred evenly, then phenmethylol, ethylene glycol, Sodium Benzoate, polyvinyl butyral are added successively, fully stir evenly.
Natural crystal is selected breezes such as ore such as quartz, calcite, feldspar, granite, marble, dolomite, the numb stone of sheet, chlorite, Black Warrior stone or iron oxide according to the design needs, require their quality hard, mud content is few more good more, and color and luster is bright and clear, and granularity is between the 30-200 order.
Natural sandstone or breeze are after cleaning, and airing can drop in the sizing material, and ore and sizing material through stirring fully, can make water soluble paint nontoxic, tasteless, that do not fire.
The exterior wall coating material that makes is treated after the aggregate sclerosis on the wall generally with the method construction of spraying, (general 24 hours), and the silicon oil liquid with 1/1000 concentration sprays cover again.
Owing to be to make aggregate, so this kind coating is not only cheap, only be 1/10 of burning colorful sand, and do not have the problem of fading with natural crystal.The metope of being decorated, profile such as stone never fade, and is natural, steady.In the process of research, we test with reference to the method for testing of the JISA6909 of Japanese Industrial Standards, and through the test of Hunan Province's construction engineering quality inspection center, the result is as follows:
| Detect content | Japan JISAS6909 standard | Testing result |
| 1, drying time 2, water resistance 3, alkaline-resisting 4, resistance to elevated temperatures 5, anti-low temperature 6, uvioresistant 7, washable wiping 8, adhesion strength | Surface drying＜2 hour are done solid work and to be soaked in 96 hours saturated lime waters of no change 46 hours no changes-5 in 24 hours ℃ 18 hours, 6 hours three times circulations of normal temperature.250 hours 500 times 0.5N/mm | Surface drying was done solid work and was soaked unchanged-20 ℃ ± 2 ℃ of 96 hours unchanged 80 ℃+2 ℃ constant temperature of unchanged immersion in 500 hours 24 hours in 20 hours 18 hours in 40 minutes; Normal temperature 6 hours, three the unchanged ultraviolet ray irradiations 4 that circulate do not have the 1.25N/mm of worn-off unchanged 1000 times round the clock |
Elaborate again with embodiment below:
One, makes sizing material 120kg in following ratio
Acrylic emulsion 105 phenmethylols 4
Ethylene glycol 3 Sodium Benzoates 0.5
Polyvinyl butyral resin 7
Two, prepare aggregate 400Kg in following ratio
Red feldspar 50 order 200Kg
The quartzy 100 order 170Kg of white
Coloured breeze 200 order 30Kg
Three, in agitator, stir sizing material earlier, then slowly with the aggregate input.Whipping temp is more than 5 ℃, and after the stirring fully, running into tank is used in order to construction.
Four, job practices and requirement:
1. Pen Tu substrate surface is answered solid clean (not having surface dust, oil stain etc.).Substrate surface is earlier with palm brush, wire brush or perching knife cleaning surface dust, loose dust etc. before the spraying.
2. the substrate surface requirement is smooth, and it is flat to reach should mending of unlikely standard, and the facing pH value should be less than 9, and moisture content can be constructed less than 10%.
3. all spraying metopes all require to do suitable ornamental lattice seam, and purpose is to be convenient to coating application to connect stubble, strengthens the texture of coating, and makes some defective of basic unit and coating itself not obvious.
4. construction temperature is preferably in more than 10 ℃, and the back 4 hours planted agents that construct avoid drenching with rain, and the coating storage temperature is preferably in more than 0 ℃.
5. use spraying method as far as possible, during as if the use knife-coat application, should flatten the trowel seal after smearing as early as possible.
6. coating is not arbitrarily added water towards rare, particularly under the situation that temperature is lower, more should not add water, otherwise can influence film-forming temperature.
When 7. spraying, nozzle requires to aim at metope, the about 50CM of distance, and air compressor machine pressure will remain 0.6-0.8MPa, and 5MM is more suitable for the nozzle diameter.
8. coating will stir if any sinking to the bottom, and nozzle will slowly move coating is fully covered at the end, survives for one time, as finds that the part do not cover the end, should in time make up a deficiency.
