Example Embodiment

[0030] figure 1 A side view of the composite structure of the protective pad 100 according to the present invention is shown. Such as figure 1 As shown, the protective pad 100 has a three-layer structure: the outer layer 1 is a flexible and stretchable elastic fiber or film material; the middle layer 2 is a buffer layer composed of a series of staggered independent buffer units 4; a base material 3 is a soft fiber or film material.

[0031] The material of the outer layer 1 is an elastic material with good tensile properties and very soft, such as polyurethane film, elastic fabric or elastic non-woven fabric material. The outer layer 1 is bonded to one end of the buffer unit 4 in the middle, and the part of the outer layer 1 between the buffer units 4 can be freely bent and stretched. Therefore, when the protective pad 100 is bent, the portion of the outer layer 1 that is not bonded to the buffer unit 4 (that is, the portion between the buffer units 4) can increase as the dista...

Abstract

The invention discloses a supplementary mat which has good bending property along all the directions to well joint wit the protected part, and a manufacturing method thereof; the supplementary mat comprises an outer layer which is elastic membrane material that is soft and has stretching performance, an intermediate layer that is composed of a plurality of buffer cells that are mutually independent and arranged in a staggered form, and base material that is soft elastic membrane material with stretching performance; wherein, the two ends of each of the buffer cells are respectively agglutinated with the outer layer and the base material. The supplementary mat also include adhesive sticker which is coated on the outward side of the base material and used for fixing the supplementary mat to the part needed to be protected.

Description

technical field [0001] The present invention relates to a protection pad and a manufacturing method thereof, in particular to a protection pad which has good bending performance in all directions so as to fit well to a protected part and a manufacturing method thereof. Background technique [0002] In the protection pad products, especially in the body protection pad products, the buffer material with rebound performance can absorb external impact and friction. After the above-mentioned buffer material is subjected to external force, its volume will be compressed, thereby absorbing external energy for the purpose of protection, and when the external force is removed, the buffer material can return to its original volume, so it can be used for a long time and repeatedly. Protective effects. [0003] However, materials with good resilience often cannot fit well the parts that need to be protected, such as the surface of the body. , the curvature of the body surface will cont...
