Problems solved by technology

Recently, some products have shown that the use of fiber-reinforced polyurethane can comprehensively solve high-strength quality problems and high thermal insulation and energy-saving problems, but the market price is extremely expensive, reaching 5 to 10 times that of various composite doors and windows with the same thermal insulation performance on the market. Extended application for large-scale construction activities

Embodiment 1

[0024] Such as Figure 1 to Figure 3 The shown FRP and reinforced plastic co-extruded door and window profiles include an inner liner made of FRP, the outer surface of the inner liner is wrapped with a surface layer made of hard plastic through co-extrusion, and the inner liner is provided with a void cavity, and reinforcing ribs are provided in the cavity; the walls of the cavity and the surfaces of the reinforcing ribs are provided with low-emissivity layers. Specifically, the wall thickness of the lining is 4mm. The number of the reinforcing ribs is two, and the two reinforcing ribs divide the cavity into three sub-cavities that may be equal or unequal in size, so as to further ensure the strength of the lining. Wherein, the thickness of the reinforcing rib is 2 mm.

[0025] The outer surface of the inner liner is covered with the hard plastic in the molten state to form a surface layer by means of co-extrusion. In the process of making the surface layer, the side wall o...

Embodiment 2

[0038] This FRP and reinforced plastic co-extruded door and window profile is the same as Example 1 except for the following technical features:

[0039] The low-emissivity layer is made of metal foil with emissivity less than 0.6. In this embodiment, the metal foil is made into a low-emissivity layer on the inner surface of the inner liner and the surface of the reinforcing rib by co-extrusion and attachment molding, so that the heat insulation performance of the entire door and window profile can be improved like the coating in Example 1. Metal foil can be gold foil or silver foil or aluminum foil.

Abstract

The invention discloses an FRP and reinforced plastic co-extruded door and window profile comprising a lining made of FRP. The outer surface of the lining is wrapped by a surface layer made of hard plastic in the co-extruded mode, the lining is provided with a cavity, and a reinforcing rib is disposed in the cavity. The wall surface of the cavity and the surface of the reinforcing rib are respectively provided with a low-radiation layer. The strength and the heat insulation performance of the profile are improved, and the cost is low.

Description

technical field [0001] The invention relates to profile technology, in particular to a co-extruded door and window profile made of glass fiber reinforced plastics and reinforced plastics. Background technique [0002] The outstanding problems to be solved for building doors and windows include improving thermal insulation and energy saving performance and improving quality levels such as strength and durability. So far, still can't find a kind of door and window profile of material can solve above-mentioned two types of problems. Recently, some products have shown that the use of fiber-reinforced polyurethane can comprehensively solve high-strength quality problems and high thermal insulation and energy-saving problems, but the market price is extremely expensive, reaching 5 to 10 times that of various composite doors and windows with the same thermal insulation performance on the market. Promotional application for large-scale construction activities. Contents of the inv...
