Aqueous polyurethane emulsion preparation method of the present invention:
Raw material weight proportioning: as previously mentioned;
The preparation method:
(1) prepolymerization reaction: (A) hydrogenated diphenyl methane diisocyanate, (C) Linear Double hydroxyalkyl siloxanes, (D) dimer acid polyester dibasic alcohol are added in the reactor, be warming up to 70-90 ℃ of reaction 2-4 hour, add (B) aliphatie diamine base sulfonate sodium, (E) 2-methyl-2 then, 4 pentanediols, the reaction of (F) 1,3 cyclohexanediol 2-5 hour;
(2) chain extending reaction: add (G) chainextender in the above-mentioned performed polymer,, be cooled to 40 ± 5 ℃ 50-80 ℃ of reaction 2-3 hour;
(3) emulsion reaction: add (H) fatty alcohol-polyoxyethylene ether TO7 and (J) deionized water, use high speed dispersor to disperse fast, product.
Aqueous polyurethane emulsion of the present invention is produced simple and convenient, and production cost is low, and solid content is up to 55%, water-fast pressing, fastness, wear-resisting, washing fastness good, aqueous, environmental protective.
The raw material hydrogenated diphenyl methane diisocyanate that the present invention selects has ring texture, ring texture is stable in the building-up process, still can exist after forming superpolymer, this structure can increase the rigidity of product, good springiness, can improve the fluffy sense of coating at water-fast, anti-solvent when wear resisting property is enhanced; The easy hydrolysis of ester bond in the conventional polyester produces chain rupture, the product instability, and the present invention selects for use the dimer acid polyester dibasic alcohol to have 36 carbon, and snappiness is splendid, has the dimeracid special construction simultaneously again, coating emulsion hydrolytic resistance obtains very big reinforcement, and stability of emulsion is improved; Linear Double hydroxyalkyl siloxanes provides soft and smooth segment, and siloxane structure has singularity, and it alternately is made of the polymer of stabilization of bony frame Siliciumatom and Sauerstoffatom.Its main chain-Si-O-Si-of polysiloxane belongs to inorganic structure, and its bond energy is higher than the bond energy of C-C key far away, and the bond energy of Si-C key is also than higher, and simple thermal motion is difficult to make Si-O key and Si-C key to rupture, thereby polysiloxane has good thermostability.The main chain of siloxanes is made up of siloxane bond in addition, and its bond length length, bond angle and bond energy are big, so siloxanes is very submissive, its viscous flow activation energy is very little, and when temperature was reduced to-136 ℃, also there was sub-chain motion in polydimethylsiloxane, and low temperature resistant, winter hardiness is special good.Secondly, do not have unsaturated link(age) on the siloxane main chain, and the Si-O-Si key is very stable to oxygen, ozone and ultraviolet ray etc., thereby has good weathering resistance.Siloxane structure determines it to have excellent hydrophobicity, he is close to the contact angle and the paraffin of water, thereby be widely used as water-proof material, reduce to handle the water-permeable and the water-absorbent of back fabric greatly, and do not destroy its ventilation property, mechanicalness and other performance, observe from molecular structure, hydroxyl links to each other with Siliciumatom on the main chain with the σ key in the Linear Double hydroxyalkyl siloxanes, increased the spatial volume that rotates freely, the hydrogen atom of hydroxyl and water hydrogen atom repel mutually, be that water molecules is difficult to combine with hydrophilic oxygen, thereby hydrophobic effect is provided.To sum up, siloxanes has improved flexibility, thermotolerance, winter hardiness, weathering resistance, hydrophobicity etc.; Adopt 2-methyl-2,4 pentanediol, 1,3 cyclohexanediol to carry out chain extension, owing to contain pendant methyl and ring texture has increased repulsion between products molecule, reduce emulsion viscosity, be able to high-load realization, further increased water-fast, anti-solvent, wear resisting property simultaneously; Select for use anionic hydrophilic group and nonionic emulsifying agent to work in coordination with effectiveness, stability of emulsion is further strengthened, and the coating penetration that the product of invention makes is better, with cloth cover to combine fastness good.Selected for use different types of hydroxyl raw material to improve performances such as product is wear-resisting, water-fast, washable, heat-resisting, cold-resistant during the present invention is synthetic.This product has good process implementing, and is environment friendly and pollution-free.Because the solids content height has not only reduced synthesis procedure, has reduced production cost, and the storing safe ready, transportation cost also reduced simultaneously.
