The invention discloses a polyurethane elastomer prepolymer synthesizing device. The polyurethane elastomer prepolymer synthesizing device comprises a stirring tank, wherein a tank body is sheathed atthe exterior of the stirring tank; a tank cover is arranged on the tank body and the upper end of the stirring tank; the inner wall of the stirring tank is provided with an installation groove; a first through hole is formed in the bottom part of the installation groove; a second through hole is formed in the inner wall of the tank body and corresponds to the first through hole; a push pipe is movably sheathed into the first through hole and the second through hole; the right end of the push pipe is fixedly connected with a piston, and the piston is positioned in the installation groove; a sampling hole is formed in the wall, near one end of the piston, of the push pipe; the end part of the left end of the push pipe extends out of the second through hole; the wall of the middle part of the push pipe is fixedly connected with a stopper; a compression spring is fixedly connected between the stopper and the outer wall of the tank body, and is movably sheathed at the exterior of the pushpipe; an air exhaust hole is formed in the wall, near the upper side of the left end, of the push pipe. The polyurethane elastomer prepolymer synthesizing device has the advantages that the sampling is quickly completed, the operation is very simple and convenient, and the stirring efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of polyurethane elastomer prepolymer synthesis, in particular to a polyurethane elastomer prepolymer synthesis device. Background technique [0002] Polyurethane elastomer prepolymer is produced by nucleophilic addition reaction between dehydrated polyalcohol and excess diisocyanate, and the nucleophilic addition reaction needs to be carried out in a special synthesis device. [0003] After searching, the Chinese patent authorization number is CN204973876U patent, which discloses a polyurethane elastomer prepolymer synthesis device, including a reactor. The reactor is provided with a jacket layer for heating and cooling, and the reactor is provided with a barrel. A stirrer is arranged in the material barrel, and a kettle lid is arranged at the opening of the reaction kettle, and the kettle lid is opened and closed by a kettle lid opening device. The polyurethane elastomer prepolymer synthesis device in the ...
