Description of the Invention: [Technical Field] The present invention relates to a method for improving a container having an insulating 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, and the selected heat-expandable particle powder is heated and dried according to the foaming initiation temperature to make the surface layer of the container form an unfoamed layer, and the The foaming layer can provide a heating temperature up to the degree of foaming on the surface layer of the container, and the surface of the attached container has the technical field of heat preservation, heat insulation and deformation of the container, and can also grasp the stock of the library. [Prior Art] In general containers, in terms of cost and use, most of them are made of paper or plastic containers, such as paper or plastic cups, bowls, plates, or made of this material. Add containers, such as packaging containers, insulated containers, lunch boxes, and the like. If foaming is used to foam the periphery of the paper or semi-finished paper product, such as U.S. Patent No. 5,952,068, which uses Acrylic, and another U.S. Patent No. 6,265,040, which has a foaming property of φ. It is foamed at 65 to 100 °C. [Summary of the Invention] 1. Problems solved: 1. The paper container is only a single layer and cannot provide insulation and heat insulation effects. If it is folded in two layers or separated by a compartment, it is used once and is used. Its cost is extremely high, which is not cost effective. 2. The plastic container is only a single layer, and there is no insulation or heat insulation effect. 3. The surface layer of the paper or plastic container is aesthetically pleasing, and at most only the surface layer is printed, and the effect of the three-dimensional pattern cannot be achieved. 4. For the paper cups currently in use, in order to prevent hot, a plastic cup is required to support the paper cup, which can prevent the anti-scalding effect of the paper cup, but the I312756 is inconvenient after the cup is cupped, and After use, the paper cup is discarded 5^, which has the original purpose of weakening the use of the paper cup. It is easy to use at low temperature ^When it is a high glass conversion point 'cpe /pp) 5 ^ 鲁 勒 勒 勒 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克 克The method is prepared for storage, and the temperature can not be mastered when needed. If the heated parts are used in the production process, the price is expensive, which does not match the paper products that are lost after being used for low prices. In Gu Yue, it is said that α 65 to 10 (rc foamable foam substrate, such as full foaming), the required foaming time will be very long, this rate μ grain deformation, damage, and moisture, etc. The problem, and the production effect 2, the means of solution: The invention is applied by using a polyurethane (Polyurethane) liquid adhesive to add the hot foamed particle powder, stirring and mixing, and then coating the composite coating on the continuous paper by coating. Setting the surface of the various plastic containers or the surface of the molded plastic container within the set range; and then drying the paper or paper container or plastic container at a heating temperature below the foaming initiation temperature The surface is adhered to the surface layer of the container by a polyurethane liquid adhesive to form an unfoamed layer; the woven container made by cutting the paper, such as the surface layer of the paper container, forms an unfoamed layer. a layer of paper or paper or plastic container having an unfoamed layer for facilitating storage, and then taking out and heating and foaming when necessary, so that the surface layer of the container forms a foam layer to provide heat insulation, heat preservation and ease Master inventory 2. The invention can form various three-dimensional patterns on the surface of various paper containers according to the pattern model, and achieves the beauty and the effect of providing the anti-scalding 1312756 which holds the protruding pattern. 3. The degree of protrusion of the aforementioned three-dimensional pattern can be coated The thickness of the composite coating is controlled by the heating temperature in the range of 100 to 140 ° C to obtain the desired degree of pattern protrusion ♦ and can be completed in a short time to overcome the problem of excessive foaming time. 4. The above-mentioned polyurethane (P〇lyUrethane) liquid adhesive is an oily polyurethane resin which can have a solidification effect during the heating and foaming process. 5. The above-mentioned heat-expandable particle powder is a thermoplastic polymer coated with a low boiling point solvent. In the shortest time, the foaming is achieved without damaging the paper product or the plastic product. The mixing ratio of the liquid adhesive and the heat-expandable particle powder is _5% to 20% by weight. The members can further understand the technical contents of the present invention, and the details of the embodiments are as follows: Please refer to the first embodiment, the manufacturing method of the present invention, which is followed by a liquid state of polyurethane (Polyurethane). Adding the heat-expandable particle powder 2, and mixing and mixing 3 to form a composite coating 4, applying a coating method, at least including spraying 5, rotating 5', color printing 5", etc., and applying the composite coating 4 to the semi-finished product 6 (After the second figure -A), the container 7 is further formed or directly coated on the surface of the finished paper container 7 (as shown in the second figure BC and the third figure A to C), and then The containers 7, 7 are dried 8 by a temperature lower than the foaming initiation temperature, so that the surface of the paper or paper container or plastic container is adhered to an unfoamed layer 9 and has no stickiness for preservation. , the heat-expanding of the unfoamed layer 9 is carried out, and the surface layer is foamed by the heat-expandable particle powder 2 to form a foamed layer u, which has a heat insulating effect. And can master the inventory.杈 Supply 阳 Yang hot corpse polyurethane (P〇lyUrethane) liquid adhesive! The oily polyurethane resin (PU) can also have a solidification effect during the heating and foaming process, which can be supplied in stock and ready to use, and will not be at room temperature; the surface position of the sticky 1312756 7 (7') is generated. After the composite coating material 4 is dried, an unfoamed layer 9 is adhered to the outer surface of the paper 6 of the semi-finished product or the container 7 (7,) for storage. Referring to the first figure, the third figure-A-C, the fourth figure-A, B, the composite coating 4 can add the coloring material 12 to make the foaming position produce a multi-color pattern; The surface of the unfoamed layer 9 adhered to the composite coating 4 after drying in the container 7 (7') is applied by color printing 5" or sprayed on the foamed position of the unfoamed layer 9 (Fig. 4B) Or a color pattern is formed on the entire unfoamed layer 9 (fourth figure-A), and then the foamed layer 11 of a color pattern is formed by heating and foaming 10. The degree of protrusion of the aforementioned three-dimensional pattern is obtained by heating temperature. 100 to 140 > °c to obtain the protruding thickness of the desired pattern after foaming.
