Description
Technical field
It the utility model is related to a kind of production system of no-solvent type polyether-polyurethane resin.
Background technology
Polyurethane（PU）Resin is that one kind has carbamate segment weight made of isocyanates and polyol reaction
The polymer of complex structure unit.Polyurethane is a kind of high polymer material, and it is mainly characterized by strand containing multiple repetitions
Carbamate groups, the elasticity of existing rubber, there are the intensity of plastics and excellent processing characteristics again, because it has rubber and modeling
The two-fold advantage of material, it is believed that be the combination of rubber and plastics excellent properties.PU products are divided into foamed product and non-foam
The major class of product two.Foamed product has soft, hard, semi-rigid foam；Non foamed product includes coating, adhesive, synthetic leather, bullet
Property body and elastomer（Spandex）Deng.
Nineteen thirty-seven Germany Otto professor Bayer has found that polyisocyanates carries out sudden reaction with polyol compound first
Polyurethane can be made, and enter the state such as industrial applications, Great Britain and America 1945-1947 based on this and obtain polyurethane tree from Germany
The manufacturing technology of fat starts to industrialize in succession in nineteen fifty.Japanese nineteen fifty-five is from German Bayer companies and DuPont
Introduce polyurethane industrial production technology.Late 1950s China's polyurethane industrial starts to start to walk, and last decade development is very fast.
The content of the invention
The utility model purpose is to provide a kind of production system of no-solvent type polyether-polyurethane resin.
Technical scheme is used by the utility model solves technical problem：A kind of no-solvent type polyether-polyurethane resin
Production system, the production system include vacuum dehydration reactor, reactor and the filter being sequentially connected；The vacuum dehydration
The discharging opening of reactor is connected with the charging aperture of the reactor, the charging aperture of the discharging opening of the reactor and the filter
It is connected；Polyethers A storage tanks, polyethers B storage tanks are connected with the vacuum dehydration reactor；Raw material storage tank is connected with the reactor, is urged
Agent storage tank and chain extender storage tank；The discharge outlet of the reactor is provided with detection sample tap；Described vacuum dehydration reactor
With pumped vacuum systems is connected with reactor.
Further, described polyethers A storage tanks, polyethers B storage tanks pass through measuring pump and the vacuum dehydration reactor phase
Even, described raw material storage tank, catalyst storage tank are connected by measuring pump with the reactor, the vacuum dehydration reactor

Tank 8；The discharge outlet of the reactor 5 is provided with detection sample tap；Connect on described vacuum dehydration reactor 1 and reactor 5
There is pumped vacuum systems 4.
Described polyethers A storage tanks 2, polyethers B storage tanks 3 are connected by measuring pump with the vacuum dehydration reactor 1, described
Raw material storage tank 6, catalyst storage tank 7 be connected by measuring pump with the reactor 5, the vacuum dehydration reactor 1 goes out
It is connected between material mouth and the charging aperture of the reactor 5 also by measuring pump and pipeline.
The filter is closed bag filter 9.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, relevant technology neck
The those of ordinary skill in domain, in the case where not departing from spirit and scope of the present utility model, can also make a variety of changes and
Modification, therefore all equivalent technical schemes fall within category of the present utility model, scope of patent protection of the present utility model should
It is defined by the claims.
