Method of manufacturing honeycomb core by spinning waste hot-press laminating

Abstract

The invention discloses a method of manufacturing a honeycomb core by spinning waste hot-press laminating. The method is characterized in that the method comprises a first step of manufacturing a flattop wave fibreboard using the spinning waste; a step of reverting the spinning waste into reprocessing fiber by cutting and opening the spinning waste, and mixing the thermoplastic spinning waste and the normal spinning waste fully in proportion; a step of manufacturing fiber nets using the obtained reprocessing fiber; a step of dealing with the fleece with preheating, mould pressing and cooling in order to manufacture the flattop wave fibreboard with a honeycomb structure; a second step of laminating and cutting a waved plate; a step of coating adhesive tapes on a wave peak of the flattop wave plate which are obtained from the first step and laminating the wave plate, comprising a way of bonding the upper layer of the wave plate with the peak of the wave plate adjacent to the upper layer in order to gain lamination of the wave plate; a step of cutting section of the lamination of the wave plate to gain the honeycomb core according to height of the honeycomb core. The method has the advantages of using rigid spinning waste, and being accurate in honeycomb core structure, little in heat exhaustion because of heating once and short in craft by relatively laminating tensile method.

Description

technical field [0001] The invention relates to a method for making a honeycomb core by hot-pressing lamination of textile waste. It belongs to the cross technical field of circular economy and building decoration materials. Background technique [0002] Circular economy refers to the general term for the reduction, reuse and recycling activities in the process of production, circulation and consumption. Reuse includes using all or part of waste as components of other products; resource utilization refers to using waste directly as raw materials or reusing waste. The invention relates to a method for making a honeycomb core by hot-pressing and compounding textile waste materials, which belongs to the technical field of recycling and recycling in circular economy. my country's textile fiber processing volume is about 30 million tons per year, accounting for more than 40% of the global textile fiber processing volume. The huge amount of textile fiber processing makes the ac...

Problems solved by technology

This kind of processing is through mechanical cutting, tearing, and opening to make the fibers untwisted. Due to the severe processing process, it is easy to break and damage the fibers. Therefore, the reprocessed fibers are short in length, miscellaneous in variety, many in color and poor in quality. Therefore, the current utilization of reprocessed fiber is very limited, and it is generally used as various filling and thermal insulation materials, with low added value.
