Field of the Invention The present invention relates to a method of manufacturing a container having an insulating surface layer, and more particularly to a method of forming a container having a foamed heat insulating layer on the surface layer. [Prior Art] In general, for the general consideration of cost and use, most of the containers are made of paper or plastic. For example, cups, bowls, plates or packagings made of paper or plastic, insulated containers, lunch boxes, etc. . However, the conventional container has the following problems: 1. The paper container is only a single layer and cannot provide insulation and heat insulation effects. If the double-layer is folded or formed into a compartment, the cost is extremely high in the use of the paper. High, it is not cost effective. 2. The surface layer of the paper or plastic container is aesthetically pleasing, and it is only printed on the surface layer, and the effect of the three-dimensional pattern cannot be formed. 3. For the paper cup that you just used, in order to prevent hot, you need to use the plastic cup as the support for the paper cup. However, if you use the net and add the cup, you still need to collect the cup. It has the convenience of reducing the use of the paper cup. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for preparing a heat-resistant surface layer. In order to achieve the above object, the method for manufacturing the insulated surface layer container of the present invention comprises the following steps: a. mixing the liquid lining agent with the heat-resistant foaming granules to form a composite 201134724 coating's toweling (four) forming agent for the nucleus And the hot foamed particle powder is formed by coating a low boiling point solvent in the thermoplastic polymer; b. coating the composite coating on at least part of the outer surface of the paper or plastic material preparation II or semi-finished product; c. The coating of the classified coating is heated to make the liquid drying agent turn softening point, and has the Wei fluidity; d. Continue to heat the composite coating to heat up, so that the low boiling point solvent coated in the thermoplastic polymer is turned The heat carrier polymer thereby forms a foaming action on the surface of the container and forms a foamed layer to form an integral with the surface of the container. Hereinafter, the technical features of the present invention and the effects achieved by the present invention will be described by way of a number of preferred embodiments, and the description will be made in the context of the present invention. [Embodiment] Please refer to Figure 1. The tolerance correction method of the (4) insulated surface layer comprises the following steps: a. The liquid gambling heat-resistant foaming particles are mixed with the age to form a composite coating, and the liquid is used to check the carrier polylactic acid, and if desired, Increase the dryness or adjust the other physical properties, etc.' can be mixed in the liquid old knot. Two are selected from the group consisting of polyvinyl acetate resin, ethyl acetate, ethyl acetate resin, polyurethane resin, polyacrylic acid. The group consisting of resin and its mixture _ (4), and the heat-resistant foamed particle powder is encapsulated in the hot-packed polymer (10), and the difficult ratio of the domain liquid enchanting agent to the New Zealand-resistant powder is (10) (4); 201134724, the composite coating is applied to at least a portion of the outer layer of the straw or semi-finished product, and the semi-finished product may be a continuous paper as shown in FIG. 2 or a non-sheet as shown in FIG. The continuous paper 2 has a predetermined shape, and the discontinuous = paper 2 can be cut by a continuous paper! and can be further formed into a container 4, as shown in Fig. 4. The above composite paint, for example Coated in a container by rotation, spraying, printing, etc. The finished product, and preferably coated on the part where the user may hold the container; c. The container coated with the composite coating is heated by a heating device to make the liquid binder reach a softening point, and has a slight Fluidity; d. continuously heating the vessel coated with the composite coating to heat, boiling the low-boiling solvent coated in the thermoplastic polymer to propp the thermoplastic polymer, thereby generating foaming on the surface of the vessel and forming - riding and forming integral with the surface of the container - as shown in Figure 5. The composite coating 6 described above can be applied to the entire surface of the container or semi-finished product, as shown in Figure 6A. Alternatively, the composite coating can be applied only to Part of the surface of the container or semi-finished product, as shown in Figure 6B, and the foamed layer formed by the composite coating is more prominent than the other surfaces, thereby forming a three-dimensional pattern. In addition, in the container or semi-finished product to be coated with the composite coating material It can be pre-rolled into a concave shape, so that when the composite coating applied to the depressed portion is foamed to form a foamed layer, the foamed layer can be flush with other surfaces. As shown in Fig. 6C, the foam layer can thereby provide the container with heat insulation effect. As shown in Fig. 7A and Fig. 7B, the foaming effect, more specifically, the 201134724 is coated with the composite paint. The heat storage is heated by the ageing device, so that the liquid spotting agent first reaches the softening point and has a slight fluidity, and then the container coated with the composite coating is continuously heated and heated to make the thermoplastic polymer 5 coated low. The boiling point solvent is boiled and swelled to form the thermal hybrid polymer 5, thereby generating a foaming gamma on the surface of the container. The towel is foamed in the side foamed particle powder due to the low impurity solution, so that a closed pore can be formed. And because the pores are not broken, the original will not form excessive pits on the surface of the hair; the touch surface, plus the secret agent, has a proper flow in the foaming process, so it can be properly filled between the hairs The gap can further reduce the surface roughness of the foamed layer, and after the gap between the expanded particles is filled with the liquid binder, the foamed layer can be made waterproof. Preferably, in the above steps c, d, the heating temperature is between 8 〇 16 〇〇 c. In addition, the foaming position can be formed in a color pattern and text in a printing manner, so that the foaming position can provide marketing information. Alternatively, a coloring material may be blended in the composite coating to impart a pattern to the foamed layer during subsequent foaming. Since the foamed layer of the present invention has a smooth surface, even if the above-mentioned color material is printed on the foamed layer by printing, the pattern and the text are not blurred. It can be seen from the above that the present invention is not only novel and practical, but also has significant advancement effects. In the case of filing a patent application according to law, it is practically pleasing to ask for a patent.
