And its products. [Previous technology] In the traditional technology, for example, composite panels such as curtain boards are usually foamed with polyvinyl chloride raw materials to form a foamed substrate layer. After the foamed substrate layer is shaped and cooled, Apply a layer of adhesive to each of the two sides 10 of the foamed base material layer, and then attach two iron plates to the adhesive layers composed of the adhesive, respectively. Metallic curtain curtain. During the manufacturing process of this traditional composite board, because the expanded polyvinyl chloride will continuously emit hydrogen chloride (HC1), the adhesive cannot be bonded at this time, so the batch 15 process must be used in the manufacturing process. That is, it is known that when manufacturing a composite board with a foamed substrate layer, the foamed substrate layer must be manufactured first, and then cut, and the foamed substrate layer can be glued and fixed after it is cooled. As for the processing process of iron plates, this batch-type processing method cannot be performed consistently, so it takes time and labor to process. 20 In order to improve the lack of continuous production of the conventional composite sheet, the applicant of this case has proposed the invention patent number 147547. The composite sheet of the invention includes: a base material layer, two glue layers and two outer layers, of which The substrate layer is extruded from polyethylene or polypropylene. Since the substrate layer extruded from polyethylene or polypropylene can be quickly cooled, the composite board provided by the Inventory 200530038 can be extruded to form the substrate layer. After that, an adhesive layer is continuously coated on the surface of the extruded substrate layer, and then the outer layer is bonded, thereby achieving the purpose of consistent processing and production of the composite sheet. The above-mentioned invention patent case uses extrusion technology to manufacture the substrate layer. Although 5 can achieve the purpose of consistent production of composite plates, as far as the manufactured product itself, the extrusion of the formed polyethylene or polypropylene substrate layer The weight is heavier than that of the conventional foamed base material of polyvinyl chloride foam molding, and its heat insulation effect is also worse than that of car cymbals. Therefore, the material characteristics of the composite sheet itself are not ideal. That is, although the patent issued by the applicant on the 10th of the month with the number of patents No. 147547 has the advantages of processing and consistency, the products made by it have the disadvantages of heavy weight and poor thermal insulation.
