Description
Technical field
The invention belongs to technical field of organic synthesis, and in particular to a kind of Diamond Search is without amine type aqueous polyurethane polyacrylic acid
The preparation method of ester.
Background technology
Aqueous polyurethane (WPU) is the new polyurethane system using water as decentralized medium, not only with burning-point it is low, it is nontoxic,
The advantages that pollution-free, saving energy and easy processing, also with excellent Optical instrument, mechanical flight of steps leading to a palace hall energy, wear-resistant and resistance to ag(e)ing
It can wait, therefore be increasingly subject to the attention of people, and start to be used for the industries such as shoemaking, building, automobile, packaging for foodstuff.State in recent years
" low-carbon " cry more and more higher on border, it is domestic that health, environment and the degree of concern of sustainable development are also further lifted, to water
The cognition degree of property coating also greatly improves.WPU materials have more or less used volatile organic solvent in production or using process
(VOC) (such as acetone, ethyl acetate or methyl pyrrolidone), therefore the WPU of Diamond Search is in the industry such as packaging for foodstuff and cosmetics
More paid attention to by people.
The anionic WPU produced both at home and abroad at present is mostly carboxylic acid type, but result of study shows that high-performance WPU is mostly sulphur
Hydrochlorate type has sulfonic acid type and carboxylic acid type concurrently.Compared with carboxylic acid type WPU, sulfonic acid type WPU stability is good, and solid content is high.Due to
The presence of hydrophilic radical, water resistance, solvent resistance and the weatherability of WPU products etc. is poor, therefore it must be modified.Research
The methods of blending of personnel's generally use physics, block copolymerization, core-shell copolymerized and graft copolymerization, improves the performance of WPU products.Will be poly-
Urethane and polyacrylate organically combine and the aqueous polyurethane~polyacrylate (WPUA) for having both advantages concurrently of preparation is
" third generation aqueous polyurethane ".But WPUA heat resistance is poor, the application in some fields is limited to a certain extent, such as
Cigarette case Flexible-Packaging Industry requires material non-toxic, non-stimulated smell, does not burn, solvent complies fully with and is less than tobacco package most
New nation's standard, without doubtful benzene peak value, hardness is high, high temperature resistance diaphragm not loss of gloss, do not turn yellow, be non-discolouring etc..
How while WPUA heat resistances are improved, ensure that its combination property does not decline or do not changed, be WPUA performances
One difficult point of research.
