Embodiment 1

[0049] (1) Weigh raw materials:

[0050] Weigh the raw materials of wood-plastic frame 1: 40 parts by weight of polyvinyl chloride, 35 parts by weight of wood powder (wood powder, aspect ratio less than 40:1, particle diameter less than 1mm), 10 parts by weight of inorganic filler, impact modified 8 parts by weight of agent, 2 parts by weight of lubricant, 2 parts by weight of stabilizer, 2 parts by weight of compatibilizer, 1 part by weight of processing aid, and 3 parts by weight of foaming agent.

[0051] (2) Manufacturing process:

[0052] First of all, according to the section design and ventilation needs, it is processed into an open profile, wherein the cross section of the metal profile can be a U-shaped, C-shaped or semi-enclosed profiled shape. In this embodiment, such as Figure 5 Metal profile 2 shown.

[0053] The composite sheet is co-extruded by an extrusion die 3 , the extrusion die 3 includes a die body 31 and a partition plate 33 , and the partition plate 3...

Embodiment 2

[0077] This embodiment produces as Figure 7 The preparation method and raw materials of the composite plate shown are basically the same as those in Example 1. The difference is that: using Figure 7 Extrusion dies and different metal profiles shown. Figure 6 The metal profiles 2 and divider panels 33 with figure 1 The positions of the metal profile 2 and the partition plate 33 in the composite plate are different, Figure 7 The web of the metal profile 2 in the composite panel is bonded to the outer layer of the composite panel (the inner wall close to the surface of the composite panel). Figure 7 and figure 1 The cross-sections at the same cutting position are basically the same, with only some differences in size.

[0078] Figure 6 Dies shown can be fabricated Figure 7 Composite panels as shown, such as Figure 6 As shown, the extrusion die 3 includes a partition plate 33 and three cores 32 .

[0079]Divider 33 and metal profile 2 surround a hollow container, ...

Embodiment 3

[0086] produce as Figure 9 Shown composite plate, its preparation method and raw material are basically the same as embodiment 2, difference is:

[0087] Extrusion die: The extrusion die 3 is only provided with a partition plate 33, but no core 32 is provided. In this way, when the composite sheet is manufactured, the partition plate 33 can form a hollow container with the metal profile 2, and the container and the mold body There is a gap for injecting molten wood-plastic material between 31, so that the molten wood-plastic foam material enters the cavity 34 and injects into the gap, forming a wood-plastic composite board on the periphery of the metal profile 2 and the partition plate 33. After the frame 1 is cooled and formed, the composite plate has only one first cavity, and the surface of the metal profile 2 is bonded to the wall of the first cavity.

[0088] Metal profile: this embodiment adopts Figure 9 The metal profile 2 is basically the same as the embodiment 2, ...

Abstract

The application provides a composite plate molded by co-extrusion of wood plastics and a metal profile. The composite plate comprises a wood-plastic frame and the metal profile, wherein a first cavity is arranged in the wood-plastic frame; the metal profile is positioned in the first cavity; the wall surface of the first cavity is bonded with the surface of the metal profile; wherein, the wood plastic framework is a foamed wood plastic material layer, and the metal profile is the opening-type metal profile. The composite plate provided by the embodiment has the advantages that the opened metal profile is selected for substituting for the closed metal profile, so that the basic strength of the composite plate is guaranteed, the usage amount of steel is saved, and conditions are created for an extrusion mold to realize internal cooling of compressed air at the same time.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a method for preparing a composite board co-extruded with wood-plastic and metal profiles. Background technique [0002] Solid clay bricks are often used for traditional building walls, which is not conducive to the protection of cultivated land; at present, wall materials such as aerated concrete blocks and hollow bricks need to be constructed on site, requiring cement wet work, generating a lot of construction waste on site and consuming a lot of labor. , The dimensional accuracy of the wall is also difficult to control, and the construction period is long, ranging from more than half a year to more than one year or even more than two years to complete. [0003] In order to meet the needs of industrialization, ecology, energy saving and green environmental protection of new buildings, Chinese patent CN102650367A provides metal and resin composite co-extrusion profiles with holes or...
