Description

Technical Field

[0001] The invention relates to the technical field of pultrusion devices, and in particular to a pultrusion device for producing polyurethane glass fiber composite materials. Background Art

[0002] Polyurethane fiberglass composites have broad application prospects in many fields due to their excellent mechanical properties, corrosion resistance and temperature resistance. This composite material is usually made by combining a two-component polyurethane resin with continuous glass fibers. During the preparation process, a two-component polyurethane resin (usually formed by mixing a polyol and a highly reactive isocyanate) is compounded with continuous glass fibers to produce a high-performance composite profile through a specific process method. The pultrusion process is an efficient and economical method for producing such composite materials. The process involves the use of a pultrusion device, under the action of a traction device, to pass a continuous fiber impregnated with resin or its fabric through a mold to heat the resin to cure the resin, thereby producing a composite profile. A key advantage of the pultrusion process is the ability to continuously produce composite materials with a fixed cross-sectional shape, which makes the process particularly suitable for large-scale production.

[0003] However, the existing pultrusion device usually only has one pulling component. During processing, the pulling component needs to be moved and reset after the pultrusion of the polyurethane glass fiber composite material stops. Therefore, it is time-consuming and affects the pultrusion processing efficiency.
