Description
Technical field
The present invention relates to building water-proof paint technical fields, and in particular to a kind of end silylated polyether water-repellent paint and its preparation
Method.
Technical background
Building water-proof paint is also known as coating film waterproof material, is that (liquid, thick liquid, pulvis add water scene to mix to amorphous material
Powder scene is added to mix and stir with liquid) coatings such as brush, scrape, smear, spray through scene and constructs, it can be in the formation of works surface cure with waterproof
The film material of ability.Since the end of the year 50 of 20th century, building water-proof paint starts large-scale use.
Different according to the substance of film-forming, building water-proof paint can be divided into organic, inorganic and organic-inorganic again
Complex class.Inorganic building water-proof paint has when ensuring of introduction, M1500, waterproof treasured, HM1500, TM1500 of country's research and development
And cement based penetration crystallization type water proofing paint.Organo-mineral complexing class has polymer cement waterproof paint.Organic buildings waterproof
Coating variety is more, and development can substantially be divided into three phases.First stage is the various emulsified asphalt coating of exploitation, from 20th century
The fifties is this just emulsified asphalt coating based on emulsifier develops the emulsification of asphalt by lime.These coating were once
The use of large area is obtained in waterproofing work, but because its waterproof effect is general, film service life is short, to environment dirt
Dye and the harm to human health, have been put into obsolete product, dosage is fewer and fewer mostly.Second stage is that exploitation polymer changes
Property asphalt waterproofing paint.There is solvent type chloroprene rubber asphalt waterproofing coating in middle 1960s, occur the seventies
There is emulsion type (cationic) chloroprene rubber waterproof coating, emulsion type the beginning of the eighties in emulsion type reclaimed rubber asphalt waterproofing paint
Butadiene-styrene rubber water-repellent paint, SBS rubber asphalt solvent-type waterproofing paint, butadiene acrylonitrile rubber cream water-repellent paint etc..Phase III is synthesis
The appearance of high molecular water-proof paint, as oleic series water-repellent paint, acrylic acid-acrylic it is fine-styrene multi-component copolymer emulsion type
Coating, aqueous EPDM water-repellent paint, polyurethane water-proof paint, spray polyurea waterproofing coating etc..
Currently on the market using in wider building water-proof paint, applied with polyurethane water-proof paint, polymer cement waterproof
Material, water-proof acrylic acid paint, based on modified waterproof asphalt material.According to statistical data in 2015, national building water-proof paint
Total sales volume is 380,000 tons, in which: polyurethane water-proof paint accounts for 43%, and polymer cement waterproof paint accounts for 37%, polyacrylic water-proof
Coating accounts for 8.5%, and modified waterproof asphalt material accounts for 5.5%, other class water-repellent paints account for 5%.
Polyurethane water-proof paint has excellent elasticity and low temperature flexibility, and yield is high, type is more, but also has current difficulty
The shortcomings that overcome.Maximum dosage is tar polyurethane waterproofing paint, Pitch-Polyurethane Water Proofing Coating and coumarone tree
Rouge modified polyurethane paint, and mostly two-component.Although tar polyurethane waterproofing paint have reactivity, it is at low cost,
It is easy to spread, but wherein containing volatile substances such as a large amount of anthracene, naphthalene, phenols, it is serious to pollute environment and be detrimental to health,
Current provinces and cities many at home, which have begun, to be forbidden to use.Pitch-Polyurethane Water Proofing Coating joined asphalt, have outer
The advantages that seeing smooth, glossy, good leveling property, elongation percentage increase, but disadvantage is also clearly.Asphalt is without active
Hydrogen only plays filler effect in coating；And wherein the heterocyclic compounds such as sulphur, oxygen, nitrogen have certain toxicity；Due to hating for pitch
Water effect affects to the recoatability of coating.Coumarone indene resin modified polyurethane water-repellent paint is to improve tar oil type
With the shortcomings that pitch type on develop, although properties have some improvement, the polyurethane coating of these three types is equal
There is deeper color, tar oil type and pitch type are black, and coumarone indene resin modified version is that coffee color arrives dark brown, which also limits
Its use scope.Although white polyurethane water-repellent paint, aqueous polyurethane water-repellent paint, single group have also been developed currently on the market
Divide polyurethane water-proof paint, although these coating solve the problems, such as existing: first is that coating property some aspects also need
It improves；Second price is higher, and acceptance level is smaller；Third is also the most key problem, and curing mechanism is still identical, system
In still containing free isocyanide ester, such as TDI, MDI, toxicity is big, easily carcinogenic.Its resistance to ag(e)ing is also relatively poor, sunlight irradiation
Easy xanthochromia down.Although and one-can urethane coating easy construction, thickness are also easy to produce bubble when applying, generate paint film defect, lead
Cause waterproof hidden danger.And the polyurethane/polyurea water-repellent paint and pure polyurea water-proof developed by polyurethane water-proof paint technology applies
Material also deposits identical problem.
Pigments and fillers and auxiliary agent mixing are added generally using acrylate polymer emulsion as film forming matter in water-proof acrylic acid paint
Made of water-based mono-component water-repellent paint.It has the characteristics that easy for construction, aqueous, environmental protective, but due to its membrane formation mechanism be with
With the continuous evolution of moisture, polymer particle is closer to each other as viscous particle for the volatilization of moisture, and polymer particle occurs
Plastic deformation and cohesion and form a film, completely physical action, therefore limit execution conditions and its film performance.It is modified
Pitch class water-repellent paint can be divided into solvent type and emulsion type, and the pollution of solvent type modified waterproof asphalt material is big, gradually now
It eliminates；Emulsion type modified waterproof asphalt material is although cheap, but resistance to ag(e)ing, weather-proof poor, and is black
Or Dark grey, it is restricted its use.
Currently, the development trend of building water-proof paint industry is Devoting Major Efforts To Developing high-performance, high durable water-repellent paint, develop ring
Guarantor's type water-repellent paint.The development of high-performance, high durable water-repellent paint is conducive to improve the time limit of setting up defences of buildings waterproof, extends and build
The investment built the object service life, reduce maintenance cost in the unit time.So the water-repellent paint of mainstream such as polyurethane is anti-currently on the market

The working principle of the invention is:
End silylated polyether resin in coating is exposed in atmosphere, with atmosphere after construction in the presence of a catalyst
In hydrone react generation crosslinking, to form waterproof coating.Its specific mechanism is to be rapidly hydrolyzed into silanol group under,
Silanol group occurs bunching again and generates three-dimensional net structure, is shown below:
And filler material, which is added, can play reinforcement, reduce cost, improve the effects of application property.Sulphur is mainly used in the present invention
Hydrochlorate, silicate and carbonate filler material.It is existing for example: sulfate filler material mainly has barium sulfate.Barium sulfate is acidproof, resistance to
Alkali, fast light, heat-resisting, oil absorption is low, is good inert filler.Barium sulfate can be divided into natural and two classes of synthesis, naturally be
Blanc fixe, synthesis are blanc fixe.Blanc fixe oil absorption is low, fillibility is good, good leveling property；Blanc fixe whiteness
High, quality exquisiteness, this project will be selected by investigating to it.Silicates filler have talcum powder, kaolin, wollastonite,
Mica powder, sericite, synthetic aluminium silicate etc..Talcum powder crystal category monoclinic system is in hexagon or diamond shape.Talcum powder can improve
The storage characteristics of coating, but it is easy dusting.Kaolin property is similar with talcum powder.The main component of wollastonite is calcium metasilicate, can
To improve the wearability and weatherability of film, the reason is that thin slice is stacked in film due to his sheet and fibrous structure,
In addition to the shielding that can increase film, there are also stronger ultraviolet reflection abilities, thus improve the resistance to ag(e)ing of film.Mica
From the point of view of powder chemically forms, it is exactly silicon a part in the lattice of talcum powder replaced aluminium, anti-corruption can be improved in coating
Corrosion increases surface hardness.Sericite in powder also has similar property with synthetic aluminium silicate.Carbonate mainly has calcium carbonate.Carbon
Cost is relatively low for sour calcium, is to use more filler at present.After fatty acid is surface-treated, have with resin preferable compatible
Property, it can obviously improve the processing performance and mechanical property of sealant.Studies have shown that the calcium carbonate superfine powder through fatty acid treatment, no
But system can be made to obtain good mechanical property, moreover it is possible to provide thixotropy, system is made to obtain good rheological property.This is mainly
Since the fatty acid Long carbon chain of treated calcium carbonate surface can be twined with pfpe molecule chain at intermolecular force and segment
Knot, the dispersion effect in coating are more preferable；Discovery is tested simultaneously, when dosage is identical, calcium carbonate partial size is smaller, the drawing of sealant
It stretches intensity and elongation at break is higher, this is because particle diameter is smaller, specific surface area is bigger, the surface area with polymer contact
More, reinforcement point increases.
The main component of coating disclosed by the invention is end silylated polyether resin, and main chain is propylene oxide polyethers flexible
Segment, end group is the siloxy with reactivity, therefore the solidification process of coating is the moisture in siloxy group and air
Reaction is realized by its hydrolysis and condensation be crosslinked in the presence of a catalyst, to obtain the elastomer with cross-linked structure.End group
The hydrolysis-condensation reaction speed of siloxy and the completeness of reaction influence workability and service performance to a certain extent, packet
Include coating surface drying time, elongation percentage and caking property etc..In general, hydrolyzable alkoxy number more more then moons are easy on silane
Hydrolytic condensation, much faster than dialkoxy silicane hydrolytic condensation such as trialkoxy silane, the former can not have to catalyst
Vulcanization crosslinking and the latter is carried out to need to there is crosslinking that could be relatively good in catalyst.Coating is from liquid to solid chemical reaction
Process are as follows: end of the chain Si-OR group first in air water occur hydrolysis generate Si-OH, obtained Si-OH again with Si-
Condensation forms Si-O-Si key between OR condensation or two Si-OH, while releasing by-product H2O or CH3OH, eventually form with
Si-O-Si key is network cross-linked point, is the cross-linked structure of propylene oxide polyether segment flexible between crosslinking points.Sealing glue solidifying
In the process, it is that condensation reaction is hydrolyzed with steam in the Si-OR group that outer layer is contacted with air first, forms chemical crosslinking, reach
It is attached on finger to adhesion without adhesiver, this process is the surface drying process of glue, and the time of experience is surface drying time.Metallic tin, iron,
Fatty acid salt, organic amine, titanate esters and its chelate of lead etc. can promote the crosslinking of end silylated polyether resin.
Due to the curing mechanism of this coating be coating coating after with the moisture in air under the effect of the catalyst with end silicon
Hydrolysis occurs for alkane, and then is crosslinked last film forming, therefore this coating needs to keep anhydrous state during storage, so plus
It is necessary for entering deicer.Common deicer has oxazole alkanes, p-Methyl benzenesulfonyl isocyanate class, triethyl orthoformate class
And organic silicon.
The addition of other components also has optimization castering action to the respective performances of coating in this coating.
