Method for manufacturing honeycomb core with filling material by using textile waste

Abstract

The invention discloses a method for manufacturing a honeycomb core with a filling material by using textile waste. The method for manufacturing the honeycomb core with the filling material by using the textile waste is characterized by comprising the following steps: the first step is reverting the textile waste to reprocessing fibers, and preparing two kinds of fiber felts by using the obtained fibers, wherein the thermal properties of the two kinds of fiber felts are different, one of the fiber felt comprises thermoplastic fibers and the other fiber felt does not comprises thermoplastic fibers, and coating hot melting rubber bars on the fiber felt without the thermoplastic fibers at the intervals of three times of the length of the side of the honeycomb core, wherein the width of each hot melting rubber bar is equal to the length of the side of the honeycomb core; the second step is compositing the two kinds of fiber felts which are prepared in the first step, pre-heating, hot-pressing and cooling the composite body of the fiber felts to form semi-finished honeycomb core; and the third step is cutting the semi-finished honeycomb core prepared in the second step into a plurality of pieces of honeycomb core strips with required height, pre-heating the honeycomb core strips, drawing the honeycomb core strips along the sections of the honeycomb core strips, unfolding the honeycomb core strips, cooling the honeycomb core strips, and then obtaining the hexagonal honeycomb core. According to the method for manufacturing the honeycomb core with the filling material by using the textile waste, the mechanical property of the honeycomb core can be improved by using the poor-qualified rigid textile waste, cost is reduced, and heating insulation performance and sound insulation performance of the honeycomb core are improved.

Description

technical field [0001] The invention relates to a method for making a honeycomb core with filling material from 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 with a filling material from textile waste, 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 accumulation of te...

Problems solved by technology

The inner hole medium of the honeycomb panel is air. Although each honeycomb unit is an independent space, there is no convection with the adjacent honeycomb unit, and there is a certain degree of heat preservation, but the inner space of the two panels in each unit space still produces convection. Therefore, its thermal insulation performance is relatively poor, and the sound insulation performance is even worse, mainly relying on the two panels to play the role of sound insulation.

Therefore, these honeycomb panels are far from meeting the needs of modern engineering
