Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] Such as figure 1 Shown is a schematic diagram of the present invention.

[0041] A closed-cell foam material, comprising a body 100, the body 100 is integrally formed by continuous foaming, the body 100 includes an upper skin 110, a central core layer 120 and a lower skin 130, the upper skin 110, the central core layer 120 and the lower skin 130 are integrally formed by continuous closed-cell foaming, the upper skin 110 and the lower skin 130 are smooth surfaces, and the core layer 120 is provided with a porous body 140 .

[0042] The continuous closed-cell foaming of the present invention is integrally molded, and the appearance of the foamed product is the same as that of IXPE and EVA molded foaming. No need to invest in high cost of equipment; molded foaming cannot be produced continuously, resulting in high labor costs and energy consumption; specifically,...

Abstract

The invention relates to the technical field of foaming materials, and in particular relates to a closed-cell foaming material as well as a manufacturing formula and a manufacturing method thereof. The closed-cell foaming material comprises a body, wherein the body is integrally molded through continuous foaming; the body comprises an upper surface skin, a middle core layer and a lower surface skin; the upper surface skin, the middle core layer and the lower surface skin are integrally molded through continuous closed-cell foaming; a formula of the foaming material comprises 10 to 40 parts of elastomers (including EVA (Ethylene-vinyl Acetate copolymer), POE (Polyolefin Elastomer), TPE (Thermoplastic Elastomer), TPR (Thermoplastic Rubber) and MPP (Modified Polypropylene)), 10 to 50 parts of polyethylene, 30 to 60 parts of a filling material, 6 to 20 parts of a foaming agent, 0 to 5 parts of a catalyst, 0.1 to 2 parts of a cross-linking agent, 0 to 3 parts of a lubricant and 0 to 2 parts of toner; the manufacturing method of the foaming material comprises the following steps: mixing; extruding; calendering to form a master batch; carrying out primary cooling and winding; adding the master batch into a continuous foaming tunnel furnace and carrying out closed-cell cross-linking foaming under normal pressure; carrying out secondary cooling; printing to obtain a finished product and winding. The method provided by the invention completely meets European Union standards and user requirements especially in the aspect of formamide; the closed-cell foaming material provided by the invention can be used for continuously carrying out chemical cross-linking closed-cell foaming without electron irradiation crosslinking and mould pressing.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to a closed-cell foaming material and its manufacturing formula and method. Background technique [0002] Foaming materials are made of plastics (PE, EVA, etc.), rubber (SBR, CR, etc.) and other raw materials, plus catalysts, foam stabilizers, foaming agents and other auxiliary materials, through physical foaming or cross-linking foaming, plastic and rubber A large number of fine foams appear in the foam, the volume increases and the density decreases. The soft foam material is light in weight and good in softness. It has the functions of cushioning, sound absorption, shock absorption, heat preservation, and filtration. It is widely used in electronics, home appliances, automobiles, sports and leisure industries. . [0003] However, the disadvantages of the existing foaming materials such as high density and high price limit its range of application. How to maintain the ...
