Problems solved by technology

[0003] In addition, sports pads, mattresses or various leisure pads all use foamed rubber or foamed plastic as the base material, but it is difficult for a single plastic or rubber foamed material to have good elasticity, softness and hardness.
A single rubber foam material lacks hardness and insufficient support strength. When people touch it, it is easy to form a large depression locally, which affects flexibility during exercise and makes people stand unstable.
A single plastic foam material has too much apparent hardness and lacks elasticity, and the comfort level is poor when people touch it

Embodiment 1

[0021] Such as figure 1 As shown, the base material of this composite mat is composed of five layers, and the density is 50kg / m from top to bottom. 3 1. A polyethylene cross-linked open-cell foam layer 1 with a thickness of 7.5 mm and a density of 40 kg / m 3 1. A polyethylene cross-linked closed-cell foam layer 2 with a thickness of 10 mm and a density of 50 kg / m 3 1. A polyethylene cross-linked open-cell foam layer 3 with a thickness of 5 mm and a density of 60 kg / m 3 1. A polyethylene cross-linked closed-cell foam layer 4 with a thickness of 10 mm and a density of 60 kg / m 3 1. A polyethylene cross-linked closed-cell foam layer 5 with a thickness of 10 mm.

[0022] The above-mentioned five-layer foamed materials are coils or sheets before they are compounded. First, the polyethylene cross-linked open-cell foam layer 1 and the polyethylene cross-linked closed-cell foam layer 2 are thermally compounded by a flame compounding machine to obtain Composite layer 1; polyethylene ...

Embodiment 2

[0024] Such as figure 2 As shown, the composite mat base material is composed of five layers, and the density is 80kg / m from top to bottom. 3 1. A polyethylene cross-linked open-cell foamed plastic layer 6 with a thickness of 10 mm and a density of 60 kg / m 3 , EPDM closed-cell foam rubber layer 7 with a thickness of 10mm and a density of 60kg / m 3 1. A polyethylene cross-linked open-cell foamed plastic layer 8 with a thickness of 10 mm and a density of 60 kg / m 3 1. A polyethylene cross-linked open-cell foamed plastic layer 9 with a thickness of 10 mm and a density of 80 kg / m 3 1. An EPDM closed-cell foam rubber layer 10 with a thickness of 10 mm.

[0025] The above five layers of foamed materials are coils or sheets before they are compounded. First, the polyethylene cross-linked open-cell foamed plastic layer 6 and the EPDM closed-cell foamed rubber layer 7 are thermally compounded by a flame compounding machine. , to obtain composite layer one; polyethylene cross-linked ...

Abstract

The invention provides a foam composite pad base material, which is characterized by comprising an opening foaming layer and a closed foaming layer stacked together; the opening foaming layer is a layer or multiple stacked layers, and the closed foaming layer is a layer or multiple laminated layers. The layers are firmly bonded together through an adhesive or thermal compounding. The base material provided by the invention has the energy absorption, flexibility and slow resilience of the opening foaming layer and the stability and support property of the closed foaming, is alternate hardness with softness, and comfortable and practical, and can be used as a base material for sport cushion, mattress and various leisure pads.

Description

technical field [0001] The invention relates to a base material of a foamed composite pad, which can be used as the basic material of sports pads such as wrestling mats and martial arts mats, and can also be used as the basic material of mattresses or various leisure pads. Background technique [0002] At present, many sports mats, household mats and outdoor leisure mats are made of foamed polymer materials. The performance of the mat is closely related to the cell structure of the base material. The closed-cell foam material has better resilience performance, rebounds quickly when impacted, can bounce back energy, and has good support performance; while the open-cell foam The material rebounds slowly when it is hit, and can absorb excess energy to prevent rebounding. However, the support performance of the open-cell foam material is poor, and it is easy to form severe local depressions when people contact it, which affects the flexibility of movement. Therefore, it is of g...
