Thermoplastic gasket in individual protection helmet and manufacturing method of thermoplastic gasket

Abstract

The invention relates to a thermoplastic gasket in an individual protection helmet and a manufacturing method of the thermoplastic gasket. The manufacturing method comprises the following steps: S1, taking thermoplastic elastic resin as a basic material and adding an acrylic copolymer compound modifier and an inorganic nanoparticle aid so as to obtain a thermoplastic gasket material; S2, performing injection molding on the thermoplastic gasket material to form a material, softening the material in a drying box, pressing the material in a pressing mould into single billets, and blistering the billets to form single thermoplastic gaskets; S3, stacking the plurality of single thermoplastic gaskets to form a multi-layer thermoplastic gasket, heating and softening the multi-layer thermoplastic gasket, putting the multi-layer thermoplastic gasket between a clamp and the head of a wearer, performing thermoplastic forming on the multi-layer thermoplastic gasket according to the shape of the head of the wearer to finally form the thermoplastic gasket. The gasket is manufactured by the method; the manufacturing method is simple, convenient and low in cost, and the gasket can quickly fit the head of the wearer; the layer number of the gasket can be changed at will to meet different head styles, and the gasket cannot move when being worn.

Description

technical field [0001] The invention relates to aviation equipment, more specifically, to a thermoplastic liner inside a personal protective helmet and a manufacturing method thereof. Background technique [0002] It is well known that both military and industrial protective helmets have a very strong shell, and usually there is a layer of elastic pad between the helmet shell and the wearer's head to absorb the impact energy to protect the head. In order to make the wearer wear it properly, people generally fix the liner with straps, but once a collision occurs, the position of the liner will shift, which will adversely affect the pilot's wearing stability and comfort. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thermoplastic liner inside a personal protective helmet that can completely fit the shape of the wearer's head and a manufacturing method thereof. [0004] The technical solution adopted by the pre...
