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 / (m 2 K) and above, for door and window profiles above 70 series, the structural performance and thermal insulation performance cannot meet the technical requirements of passive low-energy buildings

Embodiment 1

[0025]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 .

[0026] 2. Use the expanded vitrified microbeads produced by Weifang Chuangzhi New Material Co., Ltd., with a particle size of 3 .

[0027] 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 roun...

Embodiment 2

[0031] 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. The results are shown in Table 1 compared with the current door and window profile plan without adding expanded vitrified beads.

Embodiment 3

[0033] The similarities between this embodiment and Embodiment 1 will not be repeated, and the difference is that when producing door and window profiles: according to the following components in parts by weight: 100 parts of PVC resin, barium stearate (4 parts, through surface physical modification 2 parts of nano 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, surface modified with trimethylchlorosilane 1.6 parts of expanded vitrified microspheres, the above mixture is mixed evenly, and the known door and window profile extrusion equipment and process are used to extrude the production of door and window profiles. Compared with the current door and window profile scheme that does not add expanded vitrified microspheres, the results are shown in the table 1.

Abstract

A plastic door and window pillar profile with triangular chambers comprises a profile outer fa ade and a profile inner fa ade. The plastic door and window pillar profile is characterized in that a hollow outdoor bulge is arranged at the outer side of the profile outer fa ade, and a plurality of n-shaped reinforcing ribs are arranged in parallel inside the outdoor bulge; outer fa ade abdominal cavity beams are arranged in a position, corresponding to the outdoor bulge, at the inner side of the profile outer fa ade, and outer heat insulation chambers are arranged at the two sides of the outer fa ade abdominal cavity beams; hollow inner fa ade abdominal cavity beams are arranged at the inner side of the profile inner fa ade; an airtight triangular chamber group composed of at least 24 triangular chambers in grid arrangement is arranged inside the profile, the section of each triangular chamber is triangular, and the wall thickness of the triangular chambers is greater than or equal to 1.6 mm and smaller than or equal to 2mm; independent outer fa ade heat insulation chambers are arranged between the outer fa ade abdominal cavity beams and the airtight triangular chamber group; and independent inner fa ade heat insulation chambers are arranged between the inner fa ade abdominal cavity beams and the airtight triangular chamber group.

Description

technical field [0001] The invention belongs to the technical field of building doors and windows, and in particular relates to a plastic door and window centering 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 th...
