Abstract

The invention belongs to the technical field of porous-material additional materials, and particularly relates to a silicone-rubber porous material array with the elastic hollow fibers and a preparingmethod thereof. The porous material array comprises two layers or above of hollow fiber array structures, hollow fiber array structures of the layers adjacent up and down are intersected each other at a certain angle, and each layer of the hollow fiber array structure comprises multiple parallel elastic hollow fibers. The hollow fiber array structures obtained with the method serve as base materials, and formed buffering damping products or flexible electronic products have good compression and self-recovery capacity; different from an existing hollow silicone rubber manufacturing technology,the problems that in the prior art, the technology is complex, and the cost is high are solved, the silicone-rubber porous material array has the advantages of being simple in structure and capable of saving the labor cost, the time cost and the like, it is avoided that traditional hollow silicone rubber adopts a mold or a manual complex production technology, and different requirements of different users for 3D graphics, the geometric size and the like can be met.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing of porous materials, and in particular relates to a silicone rubber porous material array with elastic hollow fibers and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, more and more flexible electronic products and cushioning and vibration reduction products are turning to flexibility and customization, such as the cushioning layer of wearable devices and integrated chips, etc. These products not only require the normal operation of electronic components , It is also required that electronic components can be elastically deformed according to the needs of users, which also requires them to have better buffering, vibration reduction and self-recovery functions. Such requirements will undoubtedly pose a huge challenge to traditional manufacturing. The existing research and manufacture of flexible electronics is to...
