Embodiment Construction

[0014] The present invention is further described below:

[0015] A cold-bonding molding process of TPU material applied to space suits, characterized in that the process steps are as follows: (1) Film feeding: film feeding requires no tension, and the film must be sent flat and placed on the conveyor belt;

[0016] (2) Glue application: The glue application device is composed of paste wheel and paste knife. The paste wheel is an embossing wheel. The thickness of the glue on the paste wheel is controlled by the paste wheel and the paste knife. The thickness of the glue on the paste wheel is the thickness of the glue on the surface of the film;

[0017] (3) Pull cloth: Pull cloth to make the cloth and film naturally compound as far as possible, and do not apply external force, so that the pasted film will not lose its elasticity, and it is not easy to cause fabric wrinkles or film wrinkles;

[0018] (4) Low-temperature lamination: It consists of a large lamination wheel, six s...

Abstract

The invention provides a spacesuit TPU material cold bonding forming process. The spacesuit TPU material cold bonding forming process is characterized by comprising the following steps of (1) conveying rubber sheets; (2) applying glue; (3) pulling cloth; and (4) conducting low-temperature combination. The spacesuit TPU material cold bonding forming process is provided for achieving the purposes ofpressure maintaining and shape maintaining of an airtight layer. Meanwhile, the tear strength can be effectively improved. The requirements for ageing resistance, high wear resistance, puncture resistance, high reliability and long service life are met.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a cold-bonding molding process of TPU materials used in space suits. Background technique [0002] Space suits, especially extravehicular space suits, are known as the "life talisman" of astronauts. They are comprehensive protection systems made of special materials and have the characteristics of multi-level, multi-module, and multi-functional. Aviation suits have evolved from generation to generation. It also showed the concept products of space suits with futuristic colors, which are used for the exploration of the moon and Mars. In addition to functions such as cold protection, shock absorption, radiation resistance, and impact resistance, space suits also need to maintain a constant and stable positive air pressure, which is mainly played by the pressuregarment bladder. The mainstream structure of space suits is a multi-layer structural material made of high-performance fibe...
