Background technology
Polymer emulsion has been widely used in coating, adhesive, paper making additive, leather and textile auxiliary etc..Polymer
Lotion is mainly obtained by emulsion polymerization.Monomer conversion can not possibly have part unreacted monomer residual up to 100% when due to polymerization
It stays in lotion, generally 0.5 ~ 1.0%.There are harmful effects to environment for these unreacted monomers, and have strong impulse
Smell and different degrees of toxicity, can damage the health of user, such as cause skin allergy, expiratory dyspnea, headache.Therefore,
Remaining monomer in polymer emulsion is reduced as far as possible to have very important significance.
There is much the method for residual monomer, including physical method, chemical method and chemical-physical in removing polymer emulsion
Method.Physical method be remove polymer emulsion in residual monomer one of common method, wherein vaporizing extract process refer to certain temperature,
In stripper under vacuum condition, water vapour or the steam containing other inert gases are passed through polymer emulsion, utilize these
Gas contacts generated interface with liquid phase, and remaining monomer is taken away from polymer emulsion（Sheng Xinxin, shed dragon, Zhang Xin
Progress [J] the polymer material sciences and engineering of residual monomer removal methods in sub- polymer emulsions, 2013
(06):160-164.）.Though vaporizing extract process is by years of researches and improvement, but still there are many problems：For hydrophobic monomer
Removal efficiency is low；It is big for high boiling monomer energy consumption；It is easy to foaming, additional antifoaming system is needed, lotion final performance is influenced；Stripping
A small amount of steam condensation makes emulsion concentration decline in the process, and the later stage needs to concentrate；A small amount of cohesion can be all generated in stripping and concentration process
Object need to shut down cleaning, influence the production capacity of equipment.For different emulsion systems it needs to be determined that being taken off with the suitable stripping of optimization
Single process conditions, it is therefore necessary to propose the experimental provision of vaporizing extract process removing polymer emulsion monomer.
