Patent CN201610953902.6 disclose a kind of water polyacrylic acid modified polyurethane water-repellent paint and
Its preparation method and application.The water-repellent paint includes component：Water polyacrylic acid modified polyurethane copolymer emulsion, defoamer, purple
Outer absorbent, levelling agent, antioxidant, filler, the solid content of wherein water polyacrylic acid modified polyurethane copolymer emulsion are
20%~60%.The present invention realizes the chemical modification of molecular level using polyacrylate to polyurethane, effectively combines poly- third
The advantages of olefin(e) acid ester and polyurethane；And organosilicon/montmorillonite Composite modified polyurethane is utilized in the present invention, its composite modified system
Middle organosilicon and polyurethane compatibility increase, microphase separation degree reduce, while the acid-proof alkaline of polyurethane elastomer and
Water proofing property has obtained significant raising, and the polyurethane of increase rate modification more single than organosilicon is big, in addition, montmorillonite layer is with gathering
There is strong interaction between urethane, and lamella is dispersed in polyurethane matrix, can prevent that heat transfer is too fast, prevents further drop
Solution.
The content of the invention
It is an object of the invention to provide a kind of modified polyurethane waterproof material and its preparation technology, organosilicon/illiteracy is utilized
The de- composite modified polyurethane of soil so that microphase separation degree reduces, while the acid-proof alkaline and water proofing property of polyurethane elastomer
Significant raising can be obtained, the polyurethane of increase rate modification more single than organosilicon is big.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of modified polyurethane waterproof material, including with
Lower parts by weight material：
Wherein, the preparation method of modified polyurethane is：It is 2 by weight ratio:5:5:1 toluene di-isocyanate(TDI) TDI, polyethers
N220, polyethers N330 and end hydroxypropyl silicone oil mixing, the dibutyltin dilaurate of 0.05-0.1 parts is added, at 90-110 DEG C
Lower reaction 2-3h, the performed polymer of the silicon oil modified polyurethane of hydroxypropyl must be held, take 50 parts of performed polymer, be 1-3 with parts by weight:3.5-4:
2-3 montmorillonite, curing agent DMTDA and polyethers N330 mixing, stirs 30-50min, in constant temperature under 600-800r/min rotating speeds
10h is placed in 90 DEG C of baking oven, that is, obtains organosilicon/montmorillonite Composite modified polyurethane.
The preparation technology of this modified polyurethane waterproof material, step include：
1) preparation of organosilicon/montmorillonite Composite modified polyurethane；
2) material is weighed in proportion, by titanium dioxide in 100 DEG C of vacuum dehydration 1h, with toluene di-isocyanate(TDI), polyphosphoric acids
The chloro- 4,4'- diaminodiphenyl-methanes of ammonium, chlorinated paraffin, polyvinyl alcohol, 3,3'- bis-, plasticizer, fire retardant mix 3-
5h discharges；
3) organosilicon/montmorillonite Composite modified polyurethane and 2) in obtained product according to weight ratio be 1：1.5-3 mixing
After uniformly, construction coating, modified polyurethane waterproof material is obtained after solidification.
Preferably, the titanium dioxide powder fineness is 300-500 mesh.
Preferably, the plasticizer is dibutyl phthalate.
The beneficial effects of the invention are as follows：
1. the compatibility of organosilicon and polyurethane increase in composite modified system, microphase separation degree reduce, because
Montmorillonite layer limits the motion of silicone segments, makes it be difficult to be gathered into larger particle.
2. after montmorillonite and organosilicon are composite modified, the acid-proof alkaline of polyurethane elastomer has obtained significantly carrying
Height, the polyurethane of increase rate modification more single than organosilicon is big, and its reason is that Si-O bond energys are far above C-C bond energys, therefore has
Machine silicon can improve the heat endurance of polyurethane.In addition, have strong interaction between montmorillonite layer and polyurethane, and lamella disperses
It in polyurethane matrix, can prevent that heat transfer is too fast, prevent further degraded.
Embodiment
With reference to specific embodiment mode, the present invention is described in further detail, to make those skilled in the art join
Book word can be implemented according to this as directed.Obviously, described embodiment is only part of the embodiment of the present invention, rather than entirely
The embodiment in portion.
Embodiment 1：
1) preparation method of modified polyurethane is：It is 2 by weight ratio:5:5:1 toluene di-isocyanate(TDI) TDI, polyethers
N220, polyethers N330 and end hydroxypropyl silicone oil mixing, 0.05 part of dibutyltin dilaurate is added, is reacted at 90 DEG C
3h, the performed polymer of the silicon oil modified polyurethane of hydroxypropyl must be held, take 50 parts of performed polymer, be 1 with parts by weight:3.5:2 montmorillonite, consolidate
Agent DMTDA and polyethers N330 mixing, 30min is stirred under 800r/min rotating speeds, and 10h is placed in the baking oven of 90 DEG C of constant temperature,
Obtain organosilicon/montmorillonite Composite modified polyurethane；
2) following material is weighed in proportion：
By titanium dioxide in 100 DEG C of vacuum dehydration 1h, with toluene di-isocyanate(TDI), ammonium polyphosphate, chlorinated paraffin, polyethylene
The chloro- 4,4'- diaminodiphenyl-methanes of alcohol, 3,3'- bis-, plasticizer, fire retardant mix 5h dischargings.
3) organosilicon/montmorillonite Composite modified polyurethane and 2) in obtained product according to weight ratio be 1：1.5 mixing are equal
After even, construction coating, modified polyurethane waterproof material is obtained after solidification.
Comparative example 1：
Relative to water-repellent paint in embodiment 1, wherein modified polyurethane is only by organic-silicon-modified.
Comparative example 2：
Relative to water-repellent paint in embodiment 1, wherein modified polyurethane is only by imvite modified.
Method of testing：The coating being prepared in embodiment and comparative example is sprayed on alloy sheet surface, and the conjunction that will be obtained
Gold plaque passes through detection；Mechanics performance determining presses GB/T 19250-2003《Polyurethane water-proof paint》Carry out；Resistance to acids and bases with
10%HCl soaks 72h, 20%NaOH immersions 72h.
Wherein, comparative information is as shown in the table：
Alloy sheet after material spraying in embodiment 1 is separately immersed in 72h in hydrochloric acid and sodium hydroxide solution, waterproof material
The mass change of material is respectively less than 0.3%, at the same relative to material mechanical performance in comparative example 1-2 and acid-proof alkaline on
Rising, this is due to the compatibility of organosilicon and polyurethane increase in composite modified system, and microphase separation degree reduces, because
Montmorillonite layer limits the motion of silicone segments, and the resistance to acids and bases of polyurethane elastomer has obtained significant raising, improves
The polyurethane of the single modification of Amplitude Ratio organosilicon is big, and its reason is that Si-O bond energys are far above C-C bond energys.
