New description: [New technical field] This creation involves an environmentally-friendly packaging board structure with physical foaming plastic material, mainly referring to the foaming of an object formed by mixing pure gaseous gas and molten plastic. The environmental protection packaging board structure. [Prior Art] Shiplin is a method of physical development or chemical injection of bribes and plastics. The foamed material obtained by the foaming technology has the characteristics of light weight, cushioning, heat insulation, sound absorption, shock absorption, etc., and reduces the cost of raw materials. Among them, 'chemical foaming is a mixture of time-resolving chemical foaming agent and ship plastic. Such foaming agent is generally a solid powder, and liberates gas when heated, and foams and reduces the amount. Fine t-learning is a kind of occlusion compound, such as azodicarbamide (AZ〇diCarb ide), azobisisobutyl acetoin (Azobisisobutyro-nitrile for short). For example: • Az〇dicarb_ide foaming agent produces a possible carcinogen “semicarbazide hydrochloride” during the manufacturing process; therefore, many countries have banned the sale or import of Azodicarb ide foaming agents as food contact materials. product. _, this · learning Wei agent to listen to the melting of the age of foamed plastic, in the class of chemical foaming agent decomposition of toxic residues in the presence of foamed plastic, resulting in human body _ safety situation 1 the residual toxic forest Environmental protection and sweating. The organic compound, such as butadiene, pentane, the physical foaming agent may be a low boiling point of M367809 burning, petroleum acid, two stupid-prepared; », one rolling one rolling methane, etc.; but the blowing agent is flammable and The danger of poisons, ,, 'has the problem in the labor hall, so the use of this foaming agent technology is limited. Bu is said to be missing Q and there is a non-toxic gaseous inert gas as a proposal for foaming W. And the gaseous gas is not easily mixed with the solution by the addition of plastic, and foaming occurs. It is not feasible to use a gaseous inert gas as a physical foaming agent. In order to change the gaseous inert gas as a physical foaming agent, it is difficult to obtain a foamed product of uniform quality. "Many of the proposed methods of using a noble gas in a supercritical fluid state as a physical foaming agent are finely set by pressure and temperature. The supercritical inert gas will cause an increase in manufacturing cost, and for the foamed product to have a uniform pore/good appearance without a ship, it is often necessary to additionally use an additive or a chemical foaming agent. Therefore, there are still many technologies due to the use of the above-mentioned simple physical foaming agent to the injection foam molding. Unresolved, the foaming molding has to be continued. In addition, plastic products cannot be effectively recycled and reused due to some extra additives in plastic products. The well-known package body structure is often secreted by the secret dragon or other plastics, and the styrofoam is foamed by the PS polystyrene and the addition of the additive such as butyl smelting, but has residual poison and pollution problems. In order to obtain the healthy properties of the foam (four), the appearance of the product is flat, and in order to make the hair product have a good surface fineness, the foaming method of the physical foaming agent described above often requires additional use of additives, or chemical hair. Foaming agent. This kind of ^ 6 M367809. In the case of contact with the foaming products, there will still be safety concerns. In addition, I would also like to thank you for the use of pure physical foaming agents to obtain foaming and to contribute to environmental protection. The reason is that there is a need to 'use only a simple physical foaming agent without additional additives.' The obtained foaming Na (4), without additional additives, to avoid the safety concerns caused by additives, and to avoid The problem of causing environmental pollution; therefore, it can fully improve the advantages of foaming and turning to improve the efficiency of packaging board structure products. [New content] The purpose of paste making is to use a pure gaseous gas to form a foaming agent. The fusion of non-melting plastics is converted into a packaging board structure, and it has better strength, cushioning shock absorption and environmental protection. The invention has an environmentally-friendly packaging board structure with physical foaming plastic material, and has a plastic and gaseous gas. The gaseous gas can be gaseous air or pure gas, and the inert gas can be nitrogen, carbon dioxide, etc., and the gaseous state. The gas and the plastic are mixed to form a foamed plastic material, and the foamed plastic material has an outer layer and an inner layer 'and the inner layer is covered by the outer layer, and the outer layer is plastic, and the inner layer is plastic coated gas. The foaming material enables the foamed plastic material to be It has good strength and can be cushioned by the inner layer of bubbles to absorb shock absorption, heat insulation, and can be light and light, and the foaming material does not use chemical foaming agent' to ensure no residual toxic substances, and can be recycled and reused. , with environmental protection. The plastic of the present invention can be a hot plastic pu, LDPE low density polyethylene, that is, poly 7 M367809 : propylene, and the foaming proportion of the foamed plastic material is 800% to 2000% of the plastic gas. [Embodiment] Please refer to the first figure. The environmentally-friendly packaging board structure with physical foaming plastic material has plastic and gaseous gas. The gaseous gas can be gaseous air or pure gaseous inert gas, and the inert gas can be It is nitrogen, carbon dioxide, ..., etc., and the gaseous gas is mixed with plastic to form a foamed plastic material, and the foamed plastic material • the outer layer 11 of the material, the inner layer 12, and the inner layer 12 is covered by the outer layer π, and the outer layer is The plastic and inner layer 12 are plastic coated bubbles 121, and the plastic can be τρυ thermoplastic, LDPE low density polyethylene, pp polypropylene, and the foaming proportion of the foamed plastic material is 800%~2000 of plastic. %. The foam plastic material of the above-mentioned environmentally-friendly packaging board structure can be used by the creator of Taiwan No. _118655, the Chinese public first gift of the 1st top ship, using the gas H button for the physical transfer foaming of the county and the county. And • 1 hai case, the set amount of gaseous gas is mixed with the molten plastic, and then the plastic and the gaseous gas can be uniformly mixed by another-pressure method, and the packaging plate body of the foamed plastic material can be injection molded. The structure makes it possible to manufacture a set proportion mixture hairdressing (four) win material packaging board structure, and the foamed plastic material does not need to use chemical hair _ or additives, can be miscellaneous and toxic (four), and can be recycled with 'environmental effect . j The foregoing embodiment is presented as an example, not a limitation of this creation. This creation may be based on other plastics or other foaming ratios, and this creation may be changed and corrected within the scope of this creation 8 M367809. [Simple description of the diagram] The first picture is a schematic cross-sectional view of the physical foam plastic material of the present creation.
