Description

Technical Field

[0001] The invention relates to the technical field of types, and in particular to a circulating cooling device for pultrusion molding of a glass fiber reinforced plastic composite profile. Background Art

[0002] FRP, also known as fiber reinforced plastic, generally refers to reinforced plastics with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, with glass fiber or its products as reinforcing materials, called FRP. It is different from tempered glass. FRP profiles have a series of excellent properties such as high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, small elongation and good insulation. In recent years, they have been widely used in chemical, communication, construction and other industries. The FRP pultrusion machine for producing FRP profiles is mainly composed of a yarn frame, a frame, a dipping, a preheating device, a heating forming device, a traction device, a sawing device and a finished product frame. After the glass yarn passes through the glue tank from the yarn frame and is dipped in resin glue, it passes through the yarn plate and the preheating device to preform the mold, and then enters the heating forming device for heating. The glass yarn wrapped with resin glue is solidified and formed in the heating forming device, and is pressed and drawn out by the traction device to obtain a continuous FRP profile.

[0003] In the production of FRP, there is a cooling process for FRP, which will directly affect the quality of tempered glass and the finished product effect.
