Description
Technical field
The present invention relates to fluid sealant technical field, more particularly to a kind of system of the environment-friendly water-based water proof building fluid sealant of weather resistant
Preparation Method.
Background technology
Fluid sealant be guide deformed with sealing surface shape, be not easy to trickle, the encapsulant for having certain caking property, be for
Filling configuration gap, to play the adhesive of sealing function, be widely used in building, square, highway as inlay sealing material,
And the field such as automobile making, glass installation.
Building sealant needs excellent caking property, sealing and environment weatherability, durability, at present most of building
Fluid sealant is solvent based product, and the volatilization of organic solvent is polluted and destroyed to environment.In order to adapt to environment protection health in recent years
Development trend, aqueous architectural fluid sealant product receives more and more attention.Acrylate polymer has good stabilization
Property, physical property are affected by temperature smaller, therefore acrylic ester aquosity fluid sealant is usually used in the sealing at common buildings expansion joint.So
And weatherability, the ageing-resistant performance of acrylic acid ester emulsion such as styrene-acrylic emulsion are not ideal enough, its durability and service life are influenceed, from
And limit application of the acrylic ester aquosity fluid sealant in building field.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of environment-friendly water-based water proof building of weather resistant is close
The preparation method of sealing.
The present invention is achieved by the following technical solutions：
A kind of preparation method of the environment-friendly water-based water proof building fluid sealant of weather resistant, comprises the following steps：
（1）Raw material is weighed by weight, is first total to 10-15 parts powdered whiting, 0.5-1 parts sodium lignin sulfonate and 40-60 part water
It is dispersed with stirring uniformly with adding in container, then adds 3-5 part calcium nitrate solutions and be well mixed, be slow added into diammonium hydrogen phosphate
Solution makes calcium-phosphorus ratio be 1.6-1.67, and pH is adjusted into 10-11 and stirs 4-6h in 40-60 DEG C, is then slowly added into 0.3-0.5 parts
Silane coupling A -151 and the mixed liquor of 10-15 part absolute ethyl alcohols, it is warming up to 70-80 DEG C and continues to stir 4-6h, filtering, dry
300-400 DEG C of processing 0.5-1h, grinding are uniform afterwards；
（2）By step（1）In obtained material disperse with 30-40 parts styrene-acrylic emulsion, 10-15 parts pure-acrylic emulsion and 0.3-0.5 parts
First 1000-1500r/min disperses at a high speed 20-30min on high speed dispersor after agent mixing, then adds 1-2 part thickeners
800-1000r/min is dispersed with stirring 0.5-1h, is eventually adding 0.3-0.5 parts defoamer and stirs 20-30min under same rotating speed,
Produce the environment-friendly water-based water proof building fluid sealant of weather resistant.
Preferably, the concentration of the calcium nitrate solution is 0.2-0.3mol/L.
Preferably, the concentration of the ammonium dibasic phosphate solution is 0.2-0.3mol/L.
Preferably, the defoamer is organic silicon defoamer.
Preferably, the dispersant is polycarboxylate.
Preferably, the thickener is hydroxyethyl cellulose.
Preferably, the solid content of the styrene-acrylic emulsion is 40-50%.
Preferably, the solid content of the pure-acrylic emulsion is 50-60%.
It is an advantage of the invention that：
The present invention is carried out by the way that powdered whiting, calcium nitrate solution, ammonium dibasic phosphate solution are blended in into powdered whiting surface
The in-stiu coating of nanometer hydroxyapatite, the ethanol solution of silane coupling A -151, silane coupler are then added into system
A-151 is hydrolyzed and is grafted to nanometer hydroxyapatite surface, the nano-hydroxy-apatite to being evenly coated at powdered whiting surface
Stone carries out hydrophobically modified in situ, so as to assign nanometer hydroxyapatite modified heavy calcium carbonate powder good hydrophobicity.Should
Be mixed with building sealant as the raw material such as filler and styrene-acrylic emulsion, pure-acrylic emulsion after powder calcination, can improve filler with
The associativity of polymer emulsion, improve the adhesive property of fluid sealant, and can utilizes the dimensional network structure of hydroxyapatite, improves
The compactness of fluid sealant, so as to improve the water proofing property of fluid sealant and intensity, so as to get building sealant not only good sealing effect,
Also excellent water resistance and weatherability, intensity is high, and adhesive property is strong, and durability is good, green.
