Problems solved by technology

Due to the defects in its structural strength and deformation performance, only U-shaped, L-shaped and other shaped steel plates in the cavity can be used to reinforce and control the overall deformation.
The thermal conductivity of PVC itself is 0.17 W / (m·K), and the general heat transfer coefficient of this type of material is greater than 1.8W / (m2·K). For door and window profiles of series above 70, The structural performance and thermal insulation performance are not up to the technical requirements of passive low-energy buildings

Embodiment 1

[0026] 1. A composite material for making plastic door and window profiles, which comprises the following components in parts by weight: 100 parts of PVC resin, 4 parts of barium stearate, 2 parts of nano graphite particles through surface physical modification, chlorine 6 parts of polyethylene; 5 parts of titanium dioxide, 5 parts of activated calcium carbonate, 1.5 parts of monoglyceride stearate, 3 parts of polyacrylate, and 0.5 parts of expanded vitrified microbeads surface-modified with trimethylchlorosilane .

[0027] 2. Use the expanded vitrified microbeads produced by Weifang Chuangzhi New Material Co., Ltd., with a particle size of 3 .

[0028] 3. Nano-graphite particles with surface physical modification adopt 70-80 parts of nano-graphite powder with continuous particle size distribution of 0.8um-38um and 20-30 parts of polyethylene to compound and mix, through a single-screw mixer at 150±5 Under the conditions of ℃ and 4MPa pressure, extrude and cool to produce rou...

Embodiment 2

[0032] The similarities between this embodiment and Embodiment 1 will not be repeated. The difference is that when producing door and window profiles: according to the following parts by weight: 100 parts of PVC resin, 4 parts of barium stearate, nano 2 parts of graphite particles, 6 parts of chlorinated polyethylene; 5 parts of titanium dioxide, 5 parts of activated calcium carbonate, 1.5 parts of monoglyceride stearate, 3 parts of polyacrylate, and the expansion of surface modification with trimethylchlorosilane 0.8 parts of vitrified microspheres, mix the above mixture evenly, and extrude the door and window profiles by using known door and window profile extrusion equipment and process.

Abstract

A plastic door and window frame sectional bar with triangular cavities comprises an outer sectional bar vertical face and an inner sectional bar vertical face. A drainage channel and a first outer side heat insulation cavity are arranged on the inner side of the outer sectional bar vertical face side by side. A sealed triangular cavity group composed of at least twelve triangular cavities arranged in a meshed mode is arranged inside the sectional bar. The section of each triangular cavity is triangular. A second outer side heat insulation cavity is arranged between the drainage channel and the closed triangular cavity group. An inner vertical face web girder is arranged on the inner sectional bar vertical face. An inner vertical face heat insulation cavity is arranged between the inner vertical face web girder and the closed triangular cavity group. A composite material for manufacturing the plastic door and window sectional bar comprises, by weight, 100 parts of PVC resin, 3-4 parts of barium stearate, 1-3 parts of nano-graphite particles obtained through surface physical modification, 6-10 parts of chlorinated polyethylene, 5 parts of titanium dioxide, 5 parts of activated calcium carbonate, 1-3 parts of glyceryl monostearate, 2-3 parts of polyacrylate and 0.5-1.6 parts of expanded and vitrified small balls obtained after surface modification is performed through trimethylchlorosilane.

Description

technical field [0001] The invention belongs to the technical field of building doors and windows, in particular to a plastic door and window frame profile with a triangular cavity. Background technique [0002] At present, the domestic door and window profiles are PVC, U-PVC plastic-steel co-extrusion profiles, heat-insulating broken bridge aluminum alloy profiles, aluminum-wood composite profiles, aluminum-plastic composite heat-insulated broken bridge profiles, and so on. These profiles basically belong to three-cavity, four-cavity or multi-cavity structures (less than 20 cavities) in terms of cross-sectional structure. Due to the defects in its structural strength and deformation performance, only U-shaped, L-shaped and other shaped steel plates in the cavity can be used to reinforce and control the overall deformation. The thermal conductivity of PVC itself is 0.17 W / (m K), and the general heat transfer coefficient of this type of material is greater than 1.8W / (m 2 K)...
