Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of rapid-curing cutback building water-proof paint.
Background technique
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.Dosage is maximum for tar polyurethane waterproofing paint, Pitch-Polyurethane Water Proofing Coating and ancient horse at present
Grand resin modified polyurethane coating, and mostly two-component.Although tar polyurethane waterproofing paint has reactivity, cost
It is low, easy to spread, but wherein containing volatile substances such as a large amount of anthracene, naphthalene, phenols, serious pollution environment and harmful to human are strong
Health, many provinces and cities have begun and are forbidden to use at home at present.Pitch-Polyurethane Water Proofing Coating joined asphalt, have
The advantages that appearance is 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
The continuous evolution of moisture, polymer particle is closer to each other as viscous particle, and the plastic deformation of polymer particle occurs and coagulates
Gather effect and form a film, completely physical action, therefore film forming speed is slow, curing time is long, and restriction shortens the construction period；And be due to
By high molecular emulsion particle squeeze form a film, the water-fast, alkaline-resisting, acidproof of film, salt resistant character are poor, rich in water, alkali,
Use intensity can drop significantly in sour, salt environment, seriously affect waterproof effect and service life.
The more than needle strengths and weaknesses analysis of existing water-repellent paint, by being crosslinked of polymer emulsion, study on the modification and to painting
The optimization of material formula develops a kind of rapid draing, fast filming, quickly has physical mechanics intensity, water-fast, alkaline-resisting, acidproof,
The excellent water-based mono-component building water-proof paint of salt resistant character, to make up the deficiency of the existing water-repellent paint in market.

The present invention is used in compounding to realize film using ketone hydrazine modified polymer emulsion and silicon oxygen modified polymer emulsion
Rapid draing, and enhance this effect using coalescing agent；Other auxiliary agents, pigments and fillers are taken to improve the water-fast, resistance to of coating
Alkali, acidproof, salt resistant character.
At present it has been recognized that conventional emulsions film forming procedure mainly by carrying out in three stages: moisture evaporation first, latex
Grain is gradually mutually drawn close；Subsequent moisture continues to volatilize, and latex particle constantly damages the sealer of particle close to compression,
Gap reduces, and until forming capillary, capillary force makes latex particle compressive deformation, and intergranular interface disappears gradually；Finally
The polymer molecule end of the chain is interpenetrated, spreads, is wound, and becomes continuous paint film.In general the solid content of lotion less than 50%,
The distance between latex particle is distant.First stage and second stage in film forming procedure, with the evolution of hydrone, cream
Micelle starts to move closer to, but most close accumulation state is slowly reached between latex particle, the two stages take a long time.
If the non-deformability between the capillary force between latex particle is greater than latex particle, drying temperature are higher than minimum film formation temperature
(MFFT), latex particle deforms to form the continuous film with a large amount of polyhedral structure particles composition.In the third rank of film forming procedure
Then intersegmental part water diffusion is volatilized to polymer surfaces, the evaporation rate of this stage water is most slow.When drying temperature is greater than
The Tg of latex particle, polymer molecular chain can in the latex particle edge phase counterdiffusion of deformation, at this moment if there is no
Cross-linking reaction, the effect of the winding as caused by the diffusion of polymer molecular chain can also make paint film have certain mechanical strength.
If reaction can be crosslinked, polymer molecular chain can form relatively firm company at latex particle edge
Contact can also equally promote the mechanical strength of paint film.The diffusion of polymer molecular chain and cross-linking reaction are simultaneously deposited, then emulsion film forming
The properties for forming latex film afterwards are mainly influenced by the two factors.When cross-linking reaction rate is greater than the expansion of polymer molecular chain
Dissipate rate when, cross-linking reaction can only carry out inside each latex particle, finally formed latex film be still by being crosslinked after
It is formed with polyhedral structure latex particle, influence of the cross-linking reaction to latex film is smaller, to the solvent resistance and power of latex film
The improvement for learning performance is all poor.When the diffusion rate of polymer molecular chain is greater than cross-linking reaction rate, polymer molecular chain
Latex particle interface can be crossed, is fixed between each latex particle by cross-linking reaction, cross-linking reaction influences latex film
Larger, the latex film dynamic performance and solvent resistance formed in this case is good.Therefore, good in order to obtain film performance
Latex film, the molecular diffusion rate of polymer have to be less than cross-linking reaction rate in drying temperature.
Wherein ketone hydrazine modified polymer emulsion has important facilitation to the rapid draing of coating.
The principle of general ketone hydrazine System Modification acrylate copolymer crosslinked emulsions control crosslinking is as follows:
For ketone hydrazine System Modification acrylate copolymer self-crossing emulsion, under normal circumstances, first synthesize active
The emulsion polymer of ketone carbonyl and carboxyl is in alkalescent with volatilizable pH adjusting agent regulation system, is eventually adding soluble in water
Crosslinking agent be made can low-temperature self-crosslinking polymer emulsion.In use process, as emulsion film forming moisture constantly volatilizees, carboxyl
It is released, ketone hydrazine cross-linking reaction occurs at room temperature for catalytic activity carbonyl and hydrazide group, finally obtains with cross-linked structure
Latex film.Ketone hydrazine cross-linking reaction such as formula, water plays inhibiting effect to cross-linking reaction, therefore even if deposits jointly in carbonyl and hydrazide group
Under, lotion also has time longer storage stability.
The principle of DAAM/ADH modified acrylic polymer crosslinked emulsions control crosslinking is as follows:
Comonomer type with active ketone carbonyl is various, such as allyl aldehyde, Diacetone Acrylamide (DAAM), ethyl acetoacetic acid
Amino ethyl methacrylate (AAEM) etc..Wherein DAAM is smaller with toxicity, synthesis cost is lower, and being conducive to, which improves lotion, glues
The advantages of tying performance, DAAM are the common cross-linking monomers of lotion low-temperature self-crosslinking polymerization.Crosslinking agent containing ketone diazanyl group is main
For binary or the hydrazides of polybasic carboxylic acid, such as second acid dihydrazide, succinic acid hydrazide ii, adipic dihydrazide etc..From cross-linking effect
From the point of view of, more hydrazides crosslinking agents are got well than two hydrazides crosslinking agents, but from the aspect of cost, select the more of two hydrazides crosslinking agents.
DAAM and all kinds of monomer copolymerizables make the active ketone carbonyl of polymer molecule band, emulsion polymerization adds when completing at lotion
Suitable crosslinking agent adipic dihydrazide (ADH) is into lotion, during emulsion film forming, polymerize in the adipic dihydrazide and lotion that are added afterwards
Ketone carbonyl crosslinks reaction on object molecule, forms the latex film of cross-linked network structure, increases substantially emulsion property.
Water is as follows to the effect of the crosslinking control of DAAM/ADH modified acrylic polymer crosslinked emulsions:
Although existing simultaneously active ketone carbonyl and hydrazides group in lotion, ketone hydrazine cross-linking reaction is a reversible reaction,
When being not used, lotion is in alkalescent, and water is full of between latex particle, and cross-linking reaction is suppressed.Therefore, manufactured low temperature
Self-crossing emulsion can be long time stored without cross-linking reaction.In general, emulsion polymer is difficult to be dissolved in water, crosslinking agent oneself two
Hydrazides (ADH) is soluble easily in water, emulsion polymer containing active ketone carbonyl and adipic dihydrazide (ADH) cross-linking reaction speed compared with
Slowly.And moisture content constantly volatilizees in emulsion film forming drying process, active ketone carbonyl comes into full contact with the hydrazide group on crosslinking agent, promotes
Cross-linking reaction constantly carries out to the right, and lotion slowly becomes latex film.Cross-linking reaction, which forms polymer molecule, has net
Shape structure latex film, largely improves intermolecular bonding energy.To impart water-repellent paint rapid draing, fast filming, fast
Speed forms intensity and improves the extensibility and final strength of film, improves the water-fast, alkaline-resisting, acidproof of film, salt tolerance.
Silicon oxygen modified polymer emulsion is to the quick-drying facilitation of this coating.
Organic-silicon-modified monomer be silicone-containing group organic silicon monomer, introduce silicone-containing group monomer to polymerize
On object strand, by siloxy group at normal temperature occur dehydration and condensation reaction, make polymer self-crosslinking film-forming to
Promote the comprehensive performance of film.But in emulsion polymerization process, organosiloxane is easy to happen hydrolysis and forms silanol key,
It can occur condensation reaction again between silanol key, emulsion polymerization generates a large amount of gels and unstable.It is found by experiment that: emulsion polymerization
Acid or alkali environment has a great impact to the hydrolysis-condensation reaction of organosiloxane, when emulsion polymerization environment is in strong acid or highly basic,
It is significantly more favorable to promote the hydrolysis-condensation reaction of organosiloxane, the latex film degree of cross linking of formation is higher, can effectively promote to change
The mechanical property of kind latex film；Adding siloxanyl monomers after the pH value of emulsion polymerization is neutrality can effectively avoid siloxanes list
The generation of body hydrolysis-condensation reaction.Organosiloxane dosage increases, and the degree of cross linking of film rises, water absorption rate decline, then film
Water resistance improves；When emulsion polymerization systems are weakly acidic, it can effectively inhibit the hydrolysis for having siloxanes in emulsion polymerization process
And condensation reaction, it reduces gel and generates, keep emulsion polymerization process more stable.
Coalescing agent is as follows to the improvement result of film performance:
With the volatilization of moisture in film, high molecular polymer particle is gradually accumulated, melt and diffusion and formed.Specifically
Process is as follows:
First, stowing operation.After emulsion paint construction, as moisture gradually volatilizees, originally with electrostatic repulsion and steric hindrance
Stabilization and keep the polymer beads of dispersity and pigment, filler particles gradually to draw close, but still can be with free movement.?
The volatilization in the stage, moisture is similar to the volatilization of simple water, volatilizees for constant speed.
Second, fusion process.With the further volatilization of moisture, the protection damage layer of polymeric particle surface absorption is naked
The particle of dew contacts with each other, and gap is more and more small, until when capillary is through size, due to capillarity, capillary pressure
Higher than the anti-deformation force of polymer particles, particle deformation is finally aggregated, is fused into continuous film.This process is emulsion paint
The key that can be formed a film, if the glass transition temperature (Tg) of emulsion polymer it is higher (in order to make film have good mechanical performance,
The Tg such as weatherability and contamination value generally cannot be too low), it compared under low ambient temperature, is difficult to deform, to can make to merge
Journey is obstructed, and causes to form a film, and at this moment needs to assist to form a film with coalescing agent.Coalescing agent can be such that latex particle swelling becomes
It is soft, therefore, it is very easy to which them is made to be fused together to form continuous film.
Third, diffusion process.Auxiliary agent in water is remained gradually to painting membrane diffusion, and spread polymer long-chain mutually,
It permeates, be wound the uniform coating with superperformance.As coalescing agent is gradually volatilized from paint film, it is finally reached ideal
Paint film property.
The utility model has the advantages that
The present invention has the advantages that
1. aqueous, environmental protective, nonhazardous substance；
2. one pack system, without in addition addition curing agent；
3. room-temperature self crosslinking, without heating, rapid chemical crosslinking film forming after construction, fast drying, strength development be fast, it is water-fast,
