Description of the Invention: [Technical Field] The present invention relates to a method for improving the container with an insulated surface layer, in particular, a heat generated by a polyurethane liquid adhesive and a thermoplastic polymer coated with a low boiling point solvent. The bubble particle powder is stirred and mixed, and then applied to the outer surface layer of the target object. The selected heat-expandable particle powder is heated and dried according to the foaming initiation temperature, so that the surface layer of the container forms an unfoamed layer, and the The foam layer can provide the heating temperature up to the degree of foaming on the surface layer of the container, and achieve the adhesion. The surface layer has the technical field of heat preservation, heat insulation and deformation of the container, and the inventory can be grasped. 〃 【Prior Art】 By -, Rong ^, its generalization of reduction and use, mostly paper I or plastic containers for large, such as: paper or plastic cups, bowls, plates, or the material The finished packaging container, for example, a packaging container, a lunch box, and the like. Time, insurance, orphaning, foaming in the periphery of the paper container or semi-finished paper product, such as U.S. Patent No. 5,952,068, which uses Mokley^^crylic) and another US Patent No. 6265〇4 The nickname, which is foamed at 65 to U) 〇 °C. %,匕付f王 [Summary of the invention] First, the problem to be solved: #,1· The paper container is only a single layer, can not provide insulation, barrier double layer (four) or interval _ compartment, then use - The cost is extremely high, which is not cost-effective. Fascinated, ί.ΐίϊί is only a single layer, no insulation, heat insulation effect. Printing on the surface, and can not reach the establishment = grain = Wei 'top more than the second to prevent hot", you need to use a plastic cup for the cup, it can prevent the effect of holding the cup ^ 200831365 The upper part = the inconvenience of adding the cup, and after use, the cup is still hidden after the cup is discarded, which has the original purpose of weakening the use of the cup. v, —5· The acrylic rubber used in the above, when it is a high glass transition point, it is easy to have insufficient foaming rate at low temperature, and the container is deformed at a high temperature, and the coating layer in the paper cup (ΡΕ or ΡΡ) Damaged. Μ 6·If the acrylic adhesive with low glass transition point is used, it will easily become sticky at normal temperature. For example, if the semi-finished product is stacked, the material will be stored. If it is heated, the foaming method will occur when necessary. Unable to grasp; if using a substrate that is heated and softened at a certain temperature, it is generally applied to the process of wafer cutting or electronic component production. The price is expensive, and it is not used in the case of low price. On paper products. 7. According to the description, it is 65 to 100. 〇 foamable foam substrate, such as can achieve complete foaming on paper products, the required foaming time will be very long, this time will cause problems, such as deformation, damage, and moisture, of the paper container, and production efficiency Very low. Second, the means to solve: 1 · The present invention is applied to the use of polyurethane (Poly urethane) liquid adhesive to add hot foamed particles to mix and mix, and then apply the composite coating to the continuous paper set by coating method The surface of the various plastic containers that have been formed or formed on the surface of the formed plastic container; and then the paper or paper container or plastic container is dried at a heating temperature below the foaming initiation temperature, so that the The surface is adhered to the surface layer of the container by a polyurethane adhesive to form an unfoamed layer; the paper container formed by cutting the paper, such as the surface layer of the paper container, can form an unfilled surface. a foam layer for facilitating the storage of paper or paper containers or plastic containers having an unfoamed layer, and then taking out and heating and foaming as needed to form a foam layer on the surface layer of the container to provide heat insulation and heat preservation. Easy to grasp the amount of inventory. The invention can form various three-dimensional patterns on the surface of various paper containers according to the pattern model, and achieves the aesthetics and provides the anti-scalding effect of holding the protruding pattern. 3. The degree of protrusion of the above-mentioned three-dimensional pattern can be controlled by the thickness of the composite coating by the heating temperature in the range of 100 to 140 ° C to obtain the desired degree of pattern protrusion, and the foaming can be completed in a short time. To overcome the problem of too long foaming time. 4. The aforementioned polyurethane (Polyurethane) liquid adhesive is an oily polyurethane resin which has a solidification effect in the heating and foaming process. 5.
