Description
Technical field
The present invention relates to a kind of Polymer Synthesizing auxiliary agent and Corvic industrial circles, more particularly to a kind of antifreeze
Nontoxic organic silicon modified by polyether paste Corvic defoaming agent of type and preparation method thereof.
Background technique
Currently, China's Corvic yield is up to 1,610,000 t, wherein paste accounts for 1/4 with resin yield, is 400,000 t or so.
In PVC paste resin production process, due to using a large amount of dispersing agent in polymerization system, in the course of the polymerization process, quick
A large amount of foams are generated under stirring condition, in polymerization system, after the reaction phase system viscosity more than suspension polymerization system foam
Height can not be observed by sight glass, and vapour phase is glued wall object and increased, and it is serious to glue kettle.It must use efficient defoaming agent that could eliminate foam,
Otherwise production of resins and product quality just be will affect.
The technical characterstic of PVC paste resin defoaming agent is the dispersing agent 12 for requiring defoaming agent to use emulsion polymerization
The polyethylene of dispersing agent alcohol that sodium alkyl benzene sulfonate and microsuspension polymerization use has stronger antifoam performance, longer foam inhibition time.
But not only antifoaming speed is slow for the organic silicon defoamer of some producer's production, and the foam inhibition time is short, when occurring due to foam inhibition
Between short, the problem of also adding defoaming agent again, the dosage for increasing defoaming agent also increases the production cost of resin.So mentioning
The defoaming of height paste resin defoaming agent and suds suppressing properties are a matters of utmost importance.
Since defoaming agent is water-based emulsion, product is packed using 25-50kg plastic barrel, is used in winter, and defoaming agent is transported to
Factory has just been frozen into big " pimple ", before auxiliary agent, it is necessary to ability after in advance dissolving the workshop that charging basket is put into warm vapour
It uses.In the southern area of not heating, it is necessary to charging basket is put into Special baking room, drawing again to workshop after defoaming agent is dissolved makes
With, solve the problems, such as auxiliary agent it is antifreeze as defoaming agent production in a problem.Past is antifreeze to solve the problems, such as, has producer defoaming
Antifreezing agent is added in agent emulsion, still, defoaming agent layering is serious, so PVC defoaming agent producer of the country never solves paste tree
The antifreeze problem of rouge defoaming agent.
Currently, it solves that plastics eat the mankind, wear, living, capable and environment pollution has come into our agenda, solves
The certainly toxicity problem of plastics first has to the toxicity problem for solving auxiliary agent, produces nontoxic additive synthesis, can just produce nontoxic
Resin and product.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the present invention provides a kind of nontoxic organic silicon modified by polyether paste of anti-freeze type
With Corvic defoaming agent and preparation method thereof, make its antifoaming speed faster, foam inhibition time overlength, low production cost,
Reach domestically leading level, to China's polyvinyl chloride auxiliary agent quality is improved, reduces product cost, it is accelerating auxiliaries functionalization, nontoxic
Change, low toxicityization development has great importance.
