Adorn the fields such as agent, sheet surface treating agent and fiber surface treatment agent.But current most of aqueous PU are mainly by self-emulsification
Preparation, with the PU containing hydrophilic radical for main cure component, if hydrophilic component cannot effectively enter crosslinking when dried coating film
In network, the dry film formed is met water and is easily swollen.In addition it lacks as the getable crosslinking of two part solvent type PU film
Density and high relative molecular mass, thus the water resistance of these aqueous dispersion films, solvent resistance, heat resistance and glossiness compared with
Difference seriously limits its range used.
Epoxy resin has the characteristics such as cementitiousness strong, high mechanical strength and chemicals-resistant corrosivity is strong, and in its structure
Containing hydroxyl, it can directly react and be grafted in aqueous polyurethane segment with isocyanates, to improve aqueous polyurethane
Water-fast, solvent resistant and tensile strength etc., while resin can be increased to the adhesive force of substrate.But existing epoxy group in the reaction
It participates in reacting with hydroxyl, there is also the ring-opening reaction of carbamate and epoxy group, epoxy group is difficult to be retained in aqueous poly- ammonia
In ester, also easily make the storage stability of aqueous polyurethane emulsion bad, this greatly limits epoxy modified aqueous polyurethane materials
The application field of material.
Currently, the products such as water paint, water-based ink are all that small molecule pigment/dye is in the presence of dispersing aid and poly-
Object lotion is closed as obtained from physical blending, but since the compatibility between pigments or dyes and polymer is bad, causes to produce
There is phenomena such as sedimentation, gelatinization during storage in product.In addition in film forming procedure, pigments or dyes have transport phenomena, product
When dispersing uneven, color floats on surface of the paint film, leads to surface of the paint film floating, and moves to the pigment/dye pair on surface
Human body and environment also have great harm.According to aqueous polyurethane Molecular Design and performance basic principle, by dyes/pigments
Molecule is connected available macromolecular aqueous polyurethane dye with polyurethane backbone, and will increase improves photochromic fastness, resistance to moves
Shifting property and bio-toxicity etc..On the other hand, it needs to have using a large amount of organic solvent in the synthesis process of existing polyurethane
The problems such as use of solvent will cause environmental pollution.
