[0377] (definition of terms)

[0378] First, the terms used in the present invention are defined.

[0379] (insufficient, below, above)

[0380] "Insufficient" does not include the numerical values ​​shown below. "Below" includes the numerical values ​​shown after. "Above" includes numerical values ​​shown below. For example, less than PH7 does not contain 7, and its solution is not neutral (PH=7) but acidic. Below PH7 contains 7, so it is neutral and acidic.

[0381] (Available products, etc.)

[0382] Products to which the present invention can be applied are not particularly limited in terms of material, shape, application, etc., as long as they are resin molded products produced by injection molding, injection molding, block molding, or the like. Styrenic resins, polymer alloys and polymer blends containing styrenic resins are mainly used in OA, home appliances, game machines, and the like. In vehicles, olefinic resins or polymer alloys or blended polymers containin...

Abstract

To provide a foaming agent used to manufacture a foaming resin, an apparatus, a molding die, a molding apparatus, a means for increasing a foaming ratio, and a means for increasing the suitability of coating in a manufacturing method for obtaining molded products having a foam layer therein. Molded products having a good appearance are obtained when carrying out manufacturing using a resin exhibiting compatibility with items in which a carrier resin is to be mixed, said carrier resin to be used to manufacture a foaming resin master batch. When inorganic baking soda is used in a foaming agent, sodium carbonate in a foam residue, which remains in molded products after an effervescent gas is generated due to decomposition of the foaming agent, reduces adhesion of a coating film. Thus, when acid washing is conducted in advance to remove the sodium carbonate, a suitable coating is satisfied. When performing GCP, the thickness of a surface skin layer is altered by the molding die surface temperature. Although a means in which heated steam is used for increasing the temperature of molding dies is common, in the present invention, a means for heating a magnetic fluid (liquid) by high-frequency induction is used, thereby inexpensively providing high heating efficiency and a stable increase in the temperature of a molding die. When performing composite molding and back molding of a means for obtaining molded products having a high foaming ratio, the molding products separate from the immobilization side. The present invention provides a means for solving this separation problem by using a gas.

Description

technical field [0001] The present invention relates to a foaming agent used to obtain a foamed molded (shaped) product, a method of manufacturing a foamed molded product, a method of coating a foamed molded product, a method of manufacturing a foamed molded product made of these materials, and a process for manufacturing the foamed molded product. device. Background technique [0002] Patent Document 1 describes a foam molding method in which a molding material composed of a resin (plastic) and a foaming agent is shortshot to leave an unfilled portion in a mold in which an insert is placed, and the foaming The expansion force generated by the foaming of the agent fills the unfilled part. The resin is composed of a base material resin and a low-molecular-weight resin that is the same type as the base material resin and has a lower molecular weight than the base material resin. [0003] Patent Document 2 describes the gas counter pressure (abbreviation: GCP) method, which i...
