Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of waterborne polyurethane resin and synthetic method thereof.
Background technology
Foreign market is in great demand to PVC gloves, but because it pollutes greatly in process of production, external particularly developed country does not almost produce, and the required disposable PVC glove of its industrial production life requirement leans on import substantially.The Shijiazhuang, Hebei of China, Shandong Zibo are the production bases of national PVC gloves.But being PVC, the main raw material of PVC gloves sticks with paste resin, PVC sticks with paste resin and in compound process, adds the fluidizer of 30%-50% to increase pliability, PVC light fugitive and heat simultaneously, it is under the impact of photo-thermal, can disengage the free radical of chlorine, and cause Material degradation, therefore need to add tranquilizer and carry out Mulberry Extract.General conventional tranquilizer contains lead, cadmium, zinc, barium, the metallic salts such as tin.At present conventional fluidizer is a group chemical substance of phthalic ester (phthalic acid) on the market, and in this group of chemical substances, again with the usage quantity maximum of " phthalic acid diethylhexyl ester " (vehicle economy HP).DEHP is reproduction and growth toxin, and developmental male reproductive system is had a great impact, and the namely suffered threat of baby and child will be grown up much bigger.Adult may not had to influential dosage, child but be can not be ignored.And DEHP the MEHP of meta-bolites, Sai Tuoli Schwann Cells that can poison evil testis, causes cellular abnormality and harm fecundity.In addition, DEHP also may draw its thrombus, microthrombus, and can endanger liver and lung.Except DEHP, other phthalate generally also can impact healthy reproduction, comprises that reproduction rate reduces, miscarriage, and born defect, abnormal sperm count ， testis infringement, and cause liver cancer and kidney etc.Tranquilizer comprises lead, cadmium, zinc, barium, the metallic salts such as tin, these metals can ooze out from polrvinyl chloride product, and the wherein plumbous chronic or acute exposure that is detrimental to health can make child's nervous disorder, hinder its IQ development, women has the problem of reproduction aspect, and may be carcinogenic.Cadmium can affect renal function, and may cause lung cancer.
Party 18 large after country more and more stricter to environmental protection requirement, since 2014, the such PVC gloves production base haze phenomenon of the north each city haze phenomenon especially severe, particularly Shijiazhuang is even more serious.Chinese patent CN103622181A discloses a kind of making method of frost-cracking-preventing type PVC gloves, the content mass ratio that its PVC used sticks with paste the organic solvents such as softening agent, tranquilizer in resin reaches 40%, a large amount of organic solvent volatilizations in the production process of PVC gloves, bring great harm to shop worker, caused serious topsoil.Polyurethane glove has the following advantages than PVC gloves: good permeability, good-extensibility, residual without any organic solvent residual, heavy metal free, production process low power consuming, production environment is pollution-free etc.

2. emulsification: in the polymer obtaining, add amine neutralizing agent under the mixing speed of 1500-2500 rev/min, water carries out emulsification, finally adds amine chainextender, 800-1200 rev/min of stirring obtains the translucent resin aqueous emulsion of blue light for 5-10 minute;
3. distillation: translucent the blue light obtaining resin aqueous emulsion is proceeded in still kettle, distill 1-3h at 60-80 DEG C, the refractive index recording with refractometer is to finish distillation at 0 o'clock;
4. thickening: add thickening material in the liquid that obtains after distillation, thicken to viscosity 100-300 centipoise, obtain described polyurethane glove use resin.
Beneficial effect of the present invention is mainly reflected in the following aspects:
1. it is composite without glove factory that direct production of the present invention goes out polyurethane glove use resin, saved manpower and material resources.
The present invention in process of production organic solvent all distillation remove, belong to the environment-friendly type aqueous resin of organic solvent-free, the primary solvent of water-base resin is water.In the production process of gloves, do not need high temperature oven, organic solvent-free volatilization, has greatly improved the production environment of glove factory high temperature, high pollution, has reduced the energy consumption of gloves producers simultaneously.。
3. the polyurethane glove good permeability that the water-base resin of gained of the present invention is made, and be difficult for causing allergic; Good-extensibility, easily threading.
4. the water-base resin of gained of the present invention can stable existence, does not need to add tranquilizer, therefore not plumbous, cadmium, zinc, barium, the heavy-metal residuals such as tin.
5. adopt the elongation at break of the polyurethane glove of the water-base resin making of gained of the present invention to be far longer than PVC gloves.Following table is the polyurethane glove that does of same fingerprint and the contrast situation of PVC gloves:
