Description

Technical Field

[0001] The utility model relates to a high-temperature vacuum bag film extruder, belonging to the field of extruders. Background Art

[0002] Vacuum bag film is a process auxiliary material for the curing and forming of composite material components. It is a film material that can form and maintain a vacuum state under certain environmental conditions. The vacuum bag film used for about 400℃ is usually made of fluororubber or silicone rubber sheets by rolling. The vacuum bag film of this material can be used many times. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and form it through the die. Traditional extruders generally extrude directly at the end of the extrusion screw, and the material is extruded from the linear gap into a bag film.

[0003] Since the raw materials used to make vacuum bag films are mostly in a viscoelastic state, bubbles are bound to be mixed in, and the resistance in the extruder is relatively large, which will aggravate the impact of bubbles on the product. The extruded material will have gaps, causing large pieces of extruded vacuum bag films to be unusable and have to be recycled. How to solve this problem and obtain materials without bubbles is a technical problem that needs to be solved. Utility Model Content
