Problems solved by technology

However, since the base material of FRP doors and windows is thermosetting plastic, which is a three-dimensional network polymer structure, the profiles of FRP doors and windows cannot be recycled, which greatly increases the cost of FRP doors and windows and limits the development of the building doors and windows industry.

Embodiment Construction

[0007] As shown in the accompanying drawing, the glass fiber and its fabric on the creel (1) advance under the action of the tractor (7), absorb the thermoplastic resin polymer powder in the powder fluidized bed (2), and mix with the molten thermoplastic The resin forms the prepreg fibers. The prepreg fibers are bundled after passing through the cluster plate (3), and then the resin matrix in the prepreg fiber bundles is heated to a viscous flow state at 200°C to 240°C by the heating box (4). Under the action of traction, the molten prepreg The fiber enters the molding die (5) for pultrusion molding to obtain elastomers of PVC and PP thermoplastic materials. After the elastic body is cooled and shaped in the cooling box (6), the material reaches a certain hardness and strength, and is cut to a fixed length as required to obtain a glass fiber reinforced thermoplastic composite door and window profile.

[0008] After processing and assembling the glass fiber reinforced thermopl...

Abstract

This invention relates to a method for making a plastic door and widow section bar by glass fiber heat plasticity composite material, which uses PVC, PP plastic as basic material, and uses glass fiber untwisted yarn and its textile as reinforced material, making section bar through extrusion forming method, then makes the finished product widow. Said invention can meet market requirement for architecture widow, and the widow is lightening and has high-strength; in addition, it is insulated and energy saving, and can be recovered.

Description

1. Technical field [0001] The invention relates to a method for making plastic door and window profiles from glass fiber reinforced thermoplastic composite materials. 2. Background technology [0002] At present, plastic steel (PVC) doors and windows are doors and windows assembled from a single PVC plastic profile. It avoids the defects of poor thermal insulation performance of aluminum alloy doors and windows, and has occupied a dominant position in the building doors and windows market for a long time due to its advantages of light weight, good insulation performance, good sealing performance, and recyclability. However, since PVC plastic-steel doors and windows rely on reinforced steel as steel lining to ensure their use strength, the expansion coefficients of steel lining and PVC plastic are inconsistent, and the dimensional stability of doors and windows is poor, which greatly reduces the corrosion resistance and wind pressure resistance of PVC plastic-steel doors and ...
