Problems solved by technology

However, because the method is difficult and requires high skill, productivity is further reduced
In addition, inaccurate positioning of mask strips or separation of mask strips can further increase the reject rate
[0009] In addition, even if the coloring of the surface of the foam product is completed by the above method, the painted film will be deteriorated and stained due to careless handling or contact with other materials

Embodiment Construction

[0058] Reference will now be made in detail to the preferred embodiments of the invention which are illustrated in the accompanying drawings.

[0059] The present invention mainly includes the step of processing the foam material, the step of arranging the processed foam material in a molding mold, and the step of cross-linking and foaming the arranged foam material. The present invention may also include the steps of exposing specific portions of the foam and reshaping the foam.

[0060] In the step of processing the foamable material, the foamable material for the foam body to become the final foam body and the foamable material for the skin covering the surface of the final foam are formed in a state where cross-linking and foaming are suppressed. have a specific shape. At this time, the foamable material for the skin contains a pigment and has a film shape. In the step of arranging the processed foamable material, the processed foamable material is correctly placed in th...

Abstract

The present invention provides a manufacturing method of a cross-linked foam, comprises processing foaming material for a foam body to have a certain shape with a cross-linked foaming suppressed and processing at least one foaming material for an outer skin to have a shape of a thin film with a cross-linked foaming suppressed, the foaming material for the outer skin including a pigment; disposing the foaming material for the outer skin and the foaming material for the foam body in a molding die, the foaming material for the outer skin disposed in an inner cavity of the molding die and then the foaming material for the foam body disposed on the foaming material for the outer skin for the foaming material for the outer skin to cover a surface of the foaming material for the foam body; and cross-linked foaming the disposed foaming material for the foam body and the outer skin, whereby an united foam covered with the outer skin having a wide variety of colors can be manufactured even without an additional attachment or a painting process.

Description

technical field [0001] The present invention relates to a method of making a crosslinked foam, and more particularly to a method of making a crosslinked foam by which coverage can be easily obtained without additional attachment or painting steps Integral foam with skins in various colors. Background technique [0002] Recently, various industries are actively using foamed articles obtained by cross-linking and foaming various resins such as polyethylene (PE) or ethylene-vinyl acetate (EVA). Cross-linked foams have seen increased use due to their properties such as low specific gravity, excellent elasticity, and shock absorption. In addition, a cross-linked foam of a desired shape can be easily formed only by using a molding die having a desired shape. [0003] Since consumers tend to pay particular attention to the appearance of foam products, especially when the quality of the foam products produced by different manufacturers does not vary greatly, manufacturers have att...
