Under the global green environmental protection trend, energy conservation, resource conservation and avoidance of harmful substances have become the trend of industrial trends, thus affecting the technological development of polymer products and materials.

For example, most of the building materials, interior materials, furniture materials, etc. are still dominated by wood. However, with the rise of environmental awareness in recent years, the development of another wood substitute to reduce the development of green forest has gradually become the research and development of various manufacturers. The direction is to protect the natural ecology of the earth.

Because Wood-Plastics Composites (WPC) has a wood-like appearance and is harder than plastic, and can be reused and recycled, all manufacturers are investigating and developing applications in this field. However, the quality of such wood-plastic composites depends on the processing, and improper proportioning affects the mechanical properties of the product. In addition, there are other alternatives in which a plurality of elastic strips (such as plastic strips) are injected into the foamed material, but such substitutes can obtain hard physical properties by elastic strips, but if they are attached with iron nails, Due to the elasticity of the foamed material, it is not easy to be nailed, and it is easy to fall.

Therefore, how to develop another application can be applied to various applications (such as building materials, Composite materials such as upholstery materials, furniture materials, etc., to increase the strength of the material itself and reduce the cost of materials, has become the purpose of research and development in this case.

Therefore, the object of the present invention is to provide a composite material manufacturing method for building materials, interior decoration materials and furniture, which can increase the strength and stiffness of the material itself.

Another object of the present invention is to provide a composite material manufacturing method for building materials, interior decoration materials and furniture, and the composite material can be applied to building materials, interior decoration materials, furniture materials, etc., compared with existing wood materials. Building materials not only reduce weight, but also reduce material costs.

A method of manufacturing a composite material according to an embodiment of the present invention includes providing a sheet, immersing a sheet on a thermosetting resin, winding into a hollow shape, pouring a filler to form, and heat hardening.

Wherein, the sheet is immersed in the thermosetting resin to form a cladding material, and after the cladding material is wound to form a hollow shape, the filler is poured into the filler to expand the uncoated material, and finally the shaped cladding material is heated. The thermosetting resin is hardened.

Therefore, the composite material to which the present invention is applied, such as building materials, upholstery materials, furniture materials, etc., can achieve weight reduction and lower raw material cost compared to existing wood materials. In addition, the core material of the composite material has a reinforced design, which can increase the overall stiffness of the material.

Please refer to Figure 1, Figure 2 and Figure 3. 1 is a schematic view showing the processing of a composite material manufacturing method according to an embodiment of the present invention; FIG. 2 is a processing flow chart showing a method for manufacturing a composite material according to an embodiment of the present invention; and FIG. 3 is a view showing a composite material in an embodiment of the present invention; Schematic diagram of the structure.

The composite material manufacturing method of the embodiment of the present invention comprises providing a sheet, a immersion sheet on a thermosetting resin, winding into a hollow shape, pouring into a filler to form, heat hardening, pressing into a profile, forming an outer layer, and cooling and setting.

First, in step 110, a sheet 310 is provided. The sheet 310 may be paper, non-woven fabric, Tedron cloth, nylon cloth, glass fiber material (such as fiberglass cloth), carbon fiber material (such as carbon fiber cloth) or plastic film. .

The step 120 is transferred to a storage tank 220 by a transport wheel 210. The storage tank 220 is provided with a feeding device 230 for filling the thermosetting resin 320 in the storage tank 220. Thereby, the sheet 310 is immersed in the thermosetting resin 320 to form a covering material 330. In the present embodiment, the thermosetting resin 320 may be an unsaturated polyester, a Phenol Resin, an epoxy resin (Epoxy Resin), or a silicone resin (Silicon Resin).

In the cladding material 330, the thickness of the sheet 310 is adjusted according to the different sizes of the cladding material 330. In general, the sheet 310 has the same weight ratio as the thermosetting resin 320, and the hardness is higher as the sheet volume is smaller, so in the present embodiment, the sheet 310 and the thermosetting resin 320 occupy the covering material 330. The ratio is about 1:9, but the actual ratio still depends on the product. Various conditions (e.g., size, material, weight ratio, hardness, etc.) are contemplated, and the above ratios are only used to illustrate the embodiments described herein.

In step 130, the wrapping material 330 is wound by a mold 240 having a decreasing angle to form a hollow shape.

In step 140, a filling device 340 is used to fill a filler 340 in a hollow shape. The filler 340 may be a foamed material or a non-foamed material. Therefore, after the step 140, the filler 340 poured into the cladding material 330 can open the unshaped material of the cladding material 330 for molding to form a composite material 300.

After the composite material 300 is formed, the thermosetting resin 320 in the cladding material 330 is hardened in the step 150 through the heating zone 260, whereby the hollow coating material 330 is also shaped, that is, the embodiment of the present invention. The last composite material 300. In the heating zone 260, the heating temperature is generally between about 60 ° C and 150 ° C, and the actual heating temperature is still dependent on factors such as the heat resistance of the sheet 310, the distance of the process design, and the hardener. Further, if the heat resistance of the sheet 310 is low, the heating temperature must also be lowered, that is, the heating temperature is set to a temperature at which the thermosetting resin 320 can be chemically changed without affecting the material properties of the sheet 310. Further, in the process design, increasing the heating temperature shortens the hardening time of the thermosetting resin 320, and lowering the heating temperature extends the hardening time of the thermosetting resin 320, thereby heating the thermosetting resin 320 to gradually harden and shape it. In this embodiment, only thermosetting The resin is exemplified, but other resins which do not cause softening or dissolution after continuous heating after setting can be used as the material of the cover sheet 310.

In step 160, the composite material 300 is pressed into the desired profile 400 for use as a core material in conjunction with an extruder 270 whereby the strength of the profile 400 can be enhanced. In the present embodiment, the profile 400 is a rectangular body. Since the profile is mainly based on the profile 400, the appearance of the product can be changed according to the application of the product, such as various styles for the decorative effect. shape. Referring to the composite material examples shown in Figs. 4 and 5, in Fig. 4, the profile 400a is a plum-shaped profile, and in Fig. 5, the profile 400b is a star-shaped profile.

Step 170 forms an outer layer 410 on the profile 400 for improved appearance and protection. The method can cover the profile 400 by hot melt or apply a protective paint on the profile 400, and can also use a layer of veneer to enhance the aesthetic effect. In addition, if the application range of the profile 400 is impact-resistant, the outer surface of the profile 400 may be covered with an iron or aluminum sheet to increase strength. In the present embodiment, the outer layer 330 is a thermoplastic plastic having a thickness of about 0.5 to 3 mm. After the outer layer 410 is formed, in step 180, the profile 400 having the outer layer 410 is cooled for the purpose of final shaping.

In summary, the composite material 300 of the embodiment of the present invention can be used in a profile 400 to achieve weight reduction and lower raw material cost compared to existing materials such as building materials, interior decoration materials, and furniture materials. In addition, compound The core material design of the material 300 in the profile 400 further increases the overall strength and stiffness of the profile 400.
