Description
The present invention relates to a kind of coating, particularly a kind of construction waterproof coating.
The waterproof paint that uses on the present construction industry, comparatively general also is better performances, and a kind of is that trade name is the construction waterproof coating of JFX-1 type elastic water-proof glue, and another kind is the construction waterproof coating that is referred to as epoxy resin glue.The former has favorable waterproof property, but to concrete seepage force, poor adhesive force, coating is easily peeled off; Coating appearance is a chocolate, and decorative appearance is poor, is used for influencing behind the outer wall coating in the buildings decorative appearance of buildings.The latter's weak point is the coating tarnish, easily embrittlement behind the coating curing; Slow after the coating on the intensity generally needs 3～4 days.Coating is two components, uses, deposits, transports inconvenience.
The purpose of this invention is to provide a kind of favorable waterproof property that has, to concrete seepage force, strong adhesion, fast on the strength of coating, incrust behind the coating curing, embrittlement, both can be used as building adhesive and also can be used as construction waterproof coating usefulness, and can make as required and have the construction waterproof coating that needs color.
Construction waterproof coating adopts the methyl methacrylate powdery polymer to be the film forming component and to add anti-aging agent, fire retardant, softening agent, hydrophilizing agent, organic solvent allotment and combine, when using as waterproof paint, in composition, dose mineral filler, can add the coating that organic or inorganic pigment is deployed into needs color during as inner, external wall coating.
The constituent of construction waterproof coating is:
With the methyl methacrylate powdery polymer is aggregate, commercially available product V.V-324 or V.V-9 UV light absorber are that anti-aging agent, Ling acid three (2,3-two chloropropyls) ester is a fire retardant, dibutyl phthalate is a softening agent, methacrylic acid is a hydrophilizing agent, and any one or a few in toluene benzene, acetone, turps, acetic acid diester, N-BUTYL ACETATE, the methyl methacrylate used with and be solvent.
The proportion of composing of each constituent of construction waterproof coating is:
With methyl methacrylate powdery polymer aggregate weight is 100, V, V-327 or V, V-9 UV light absorber are 0.1～1.0, and Ling acid three (2 3-, two chloropropyls) ester is 2～20, and dibutyl phthalate is 40～100, methacrylic acid is 5～20, and solvent is 10～700.
Dosing stopping composition in the construction waterproof coating is favourable to the raising of its water resistance and use properties with improving.The stopping composition of dosing is optional to be used with any one or a few mixing in cement, zinc sulfide white, titanium dioxide, stone class sand, the refractory mortar.The amount of filling of stopping composition is 10～700% of a first methyl methacrylate powdery polymer aggregate weight.
Construction waterproof coating ideal proportion of composing is:
The methyl methacrylate powdery polymer aggregate of dosing 30～50% stopping composition of methyl methacrylate powdery polymer weight is 100, V, V-327 or V, V-9 UV light absorber are 0.2～0.3; Ling acid three (2,3-two chloropropyls) ester is 10～12, dibutyl phthalate is 60～70, methacrylic acid is 10～15, solvent is 90～200 parts, can add an amount of organic or inorganic pigment as required in the composition, forms the coating that requires color.Kind, the quantity of pigment have no particular limits, and can determine as required.
The manufacture method of construction waterproof coating film forming component methyl methacrylate powdery polymer is by volume, and the water of 100～500 parts methyl methacrylate monomer and 100～200 parts is put into normally used chemical reaction kettle heat temperature raising under stirring condition.Add in the time of heat temperature raising by weight being water: Ling acid trisodium: sodium hydroxide is 80: 2: 0.2 20～180 parts of the solution and the benzoyl peroxides of 1.0～1.8 grams, and dripping concentration when temperature rises to 80～90 ℃ is 0.9%(weight) calcium chloride water make it carry out polyreaction for 20～100 parts.Calcium chloride water dropwises the back insulation reaction made reaction carry out fully in 70～80 minutes.The polyreaction back that finishes adds 2～10 parts hydrochloric acid neutralization reaction liquid, and hydrochloric acid adds to reaction solution and is neutrality and promptly stops in actually operating, and the resultant of reaction after the neutralization is removed wherein liquid and washed with water and be precipitated to neutrality.Tell to utilize behind the wash water and filter or centrifugal separation method is further removed moisture content in the precipitation.Be after the precipitation drying of filtering moisture content and make the methyl methacrylate powdery polymer that construction waterproof coating is used.
The method for making of dosing the methyl methacrylate powdery polymer aggregate of stopping composition and pigment is methyl methacrylate powdery polymer, stopping composition, pigment are mixed and to put into that general ball mill grinds, efflorescence makes it form uniform powdery colorant by proportion scale, sieve after the grinding, screen underflow is makes the methyl methacrylate powdery polymer aggregate that construction waterproof coating is used.
The manufacture method of construction waterproof coating is: in proportion each constituent is mixed, stirring and dissolving formed homogeneous liquid in 60～70 minutes and is finished product at normal temperatures.Can be modulated into according to using method and requirement during allotment and be suitable for the coating that uses as tackiness agent or be used to smear paste coating that seam, leak stopping use or brushing, spraying coating for internal and external wall.
Can bonding marble when construction waterproof coating uses as tackiness agent, grouan, ornamental brick, mosaic, synthetic glass, plastics, timber etc.It is strong to have bonding force, advantages such as appearance looks elegant.To concrete seepage force, strong adhesion, coating is incrust when dosing stopping composition and using as water-resisting agent, and intensity can meet the requirements of intensity in general 24 hours.Coating has fire retardation can suppress stretching of flame, improved the fire savety of building sides, the coating good water absorption, humidity, the coating construction is not limited by weather, and coating quality is easy to guarantee also have good weatherability in addition, cold-resistant thermal distortion, advantage such as corrosion-resistant, acid-and base-resisting is strong.
Embodiment:
One, producing of methyl methacrylate powdery polymer:
100～500 parts methyl methacrylate monomer adds 100～200 parts in water and puts into normally used reactor stirring heating intensification by volume, add in the time of heat temperature raising by water: Ling acid trisodium: sodium hydroxide is 80: 20: the 0.2(weight ratio) benzoyl peroxide of the aqueous solution of forming and 1.0～1.8 grams, dripping concentration when temperature rises to 80～90 ℃ is 0.9%(weight) 20～100 parts of calcium chloride waters, calcium chloride water generally should dropwise at 15 minutes, drips calcium chloride water and finishes that to make it polyreaction in 70～80 minutes complete in the back insulation.After finishing, polymerization adds 2～10 parts of hydrochloric acid neutralization reaction Generation Liquids.The hydrochloric acid add-on generally is controlled at and stops to add hydrochloric acid when solution is subacidity in actually operating.In the resultant of reaction and after remove supernatant liquid, lower sediment with clear water washing till washing lotion is neutrality.Precipitation after the washing adopts methods such as filtration or centrifugation to remove the moisture content in the precipitation and be dried to powdery solid and is the methyl methacrylate powdery polymer.
The methyl methacrylate powdery polymer produced adds stopping composition and is the aggregate of construction waterproof coating with ball mill grind, the sieve meal that obtains.
Two, the preparation of construction waterproof coating:
By weight, 0.1～1.0 part of per 100 parts of aggregates adding V, V-327 or V, V-9 UV light absorber, be preferably 0.2～0.3 part, Ling acid three (2,3-two chloropropyls) ester 2～20 generally is preferably 10～12 parts, dibutyl phthalate 40～100, be generally 60～70 parts, 5～20 parts of methacrylic acids generally are preferably 10～15 parts, solvent is 10～500 parts, is generally 90～200 parts.
