Problems solved by technology

Due to the special wire drawing structure of the space cloth, the coating method of ordinary materials (such as grid cloth and various single-layer base fabrics) cannot be directly applied to the space cloth, although a good targeted coating has been developed for the space cloth. method, but the two layers of the existing space cloth are made of polyester PET fiber. For the space cloth made of the newly developed ultra-high molecular weight polyethylene fiber, it is difficult for the TPU film to fit the space cloth. , and the problem that the peel strength does not meet the standard after lamination

[0016] The invention provides a method for preparing a high-strength space cloth material, comprising the following steps:

[0017] Step 1. Put PU paste on the upper surface of the PE space cloth, put PU paste on the lower surface of the PE space cloth after drying, and apply PU paste on the upper surface of the PE space cloth after drying. Put PU paste on the lower surface again, and get pasted PE space cloth after drying;

[0018] Step 2, carrying out corona treatment on one side of the TPU film to obtain a corona TPU film;

[0019] Step 3. Preheat the upper surface of the pasted PE space cloth, and bond it with the corona-treated side of the corona TPU film; then preheat the lower surface of the pasted PE space cloth, and bond it with the corona TPU film The corona-treated side is pasted together to obtain a high-strength space cloth material;

[0020] The solid content of the PU paste is 40%-60%, the paste amount of the PU paste is 30-60gsm each time, and the viscosity o...

Abstract

The invention discloses a high-strength space cloth material and a preparation method thereof. The preparation method belongs to the technical field of composite materials. The preparation method comprises the steps that: applying a PU paste to the upper surface and the lower surface of PE space cloth twice and drying, wherein the amount of the PU paste applied each time is 30-60 gsm, and the viscosity of the PU paste is 40,000-50,000 cps; carrying out corona treatment on one surface of a TPU film; preheating the upper surface and the lower surface of the pasted PE space cloth, and respectively fitting the upper surface and the lower surface of the pasted PE space cloth with the corona-treated surface of the TPU film to obtain the high-strength space cloth material. According to the preparation method, the problems that the TPU film is difficult to fit with the PE space cloth and the peel strength after fitting does not reach the standard are solved, and the peel strength after fittingcan reach 150N / 5cm or above, so that a product prepared from the obtained space cloth material can bear higher air pressure, and the application field of the space cloth material is widened.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a high-strength space cloth material and a preparation method thereof. Background technique [0002] The space cloth is different from the mesh cloth obtained by conventional textiles. It is a 3D three-dimensional hollow structure. Its base cloth adopts 3D weaving technology, and it is an integrated structure formed by connecting two layers of sandwich cloth surfaces through the upper and lower strings of the middle drawing. According to the different walking methods of the middle drawing, different shapes of cloth surface effects can be formed, such as W shape, dot shape, straight strip shape and so on. Space cloth can provide a very stable three-dimensional space structure when used, and has the advantages of stable size, smooth surface, good resilience and high specific strength. Most of the space fabrics are used to prepare floating boards, surfboards...
