Automatic continuous production line for liquid silicone rubber

In the automatic continuous production line of liquid silicone rubber provided by the invention, the first-stage screw machine is connected with the side feeder, and the side feeder is provided with a feeding port for adding powder material and a feeding port for liquid material. The first-stage screw machine and the second-stage screw machine are respectively equipped with a vacuum device for vacuuming operation.

The material of the first-stage screw machine is cooled by a high-viscosity liquid cooler and then enters the first stage. Second-stage screw machine; powder material is added to the powder material feeding port through the powder material feeder; liquid material is added to the liquid material feeding port through the liquid material mixing feeder. Compared with the prior art, the automatic continuous production line of liquid silicone rubber provided by the present invention premixes, disperses, kneads, heats up, cools, cools down, adds auxiliary agents, and evacuates low-molecular by-products of liquid material and powder material. The other steps are integrated in a set of automatic production lines to achieve continuous production, improve the production efficiency of liquid silicone rubber, improve product quality and reduce production costs.
