One-time foaming formed high-permeability air cushion body structure and manufacturing method thereof

Abstract

The invention discloses a one-time foaming formed high-permeability air cushion body structure and a manufacturing method thereof. The mattress comprises a mattress body, wherein the pad body is formed by foaming a foaming material, and an integrally formed structure, the pad body is provided with a foaming body and a skin layer for cooling crust after being foamed and formed; and the foaming bodyis provided with a plurality of air holes, the plurality of air holes are communicated with one another, the surface layer is provided with a plurality of air holes, and the plurality of air holes ofthe foaming body are communicated with the plurality of air holes of the surface layer, so that the mattress body disclosed by the invention achieves the effect of complete ventilation.

Description

technical field [0001] The invention relates to a cushion body structure, in particular to an integrally formed highly air-permeable cushion body structure formed by one-time foaming and a manufacturing method thereof. Background technique [0002] The existing foam cushion materials are divided into PU, EVA, etc. Among them, the cushion made of PU material can be divided into closed-cell PU foam and open-cell PU foam, closed-cell PU foam When the foam is formed into a pad, a plurality of air holes will be produced on the pad, but the multiple air holes are not connected to each other, so the pad does not have air permeability, and the pad may make the user feel uncomfortable during use. It feels stuffy and airtight. The advantage of the closed-cell PU foam is that the cushion can be foamed and formed according to the shape of the mold, and there will be no excess waste. The disadvantage is that it does not have a breathable effect after forming. [0003] see diagram Figur...

Problems solved by technology

[0002] The existing foam cushion materials are divided into PU, EVA, etc. Among them, the cushion made of PU material can be divided into closed-cell PU foam and open-cell PU foam, closed-cell PU foam When the foam is formed into a pad, a plurality of air holes will be produced on the pad, but the multiple air holes are not connected to each other, so the pad does not have air permeability, and the pad may make the user feel uncomfortable during use. It feels stuffy and airtight. The advantage of the closed-cell PU foam is that the cushion can be foamed and formed according to the shape of the mold, and there will be no excess waste. The disadvantage is that it does not have a breathable effect after forming.

[0003] see diagram Figure 1 to Figure 4 , the other is an open-cell PU foam material. When foaming and forming, it needs to be foamed into a large piece of cushion A, and then cut out the required shape and range from the entire piece of cushion A to complete. A finished product A1, however, when the open-cell PU foam is formed into the cushion A, the foam A11 of the cushion A will produce a plurality of interconnected pores, but the skin layer A12 does not have pores, so The finished product A1 still does not have air permeability. If the finished product A1 needs to be air-permeable, the epidermis A12 needs to be torn off first to have the air-permeable effect. Although the foam A11 is air-permeable, the surface is rough and The advantage of the cushion body that is not wear-resistant and has air permeability is that it has good air permeability, and the overall touch is soft and comfortable. The disadvantage is that it cannot be formed at one time according to the shape range of the mold, and it needs secondary processing and cutting to complete the finished product. After forming and cutting There will be excess waste, and the skin layer needs to be torn off to have a breathable effect
