Temperature-regulation liner and preparation method and application thereof

Abstract

The invention provides a temperature-regulation liner and a preparation method and application thereof. The temperature-regulation liner comprises a linear body and a phase-change temperature regulation material. The phase-change temperature regulation material is prepared from, by weight, 150-250 parts of a phase-change material, 100-150 parts of a solvent, 1-5 parts of a softening agent, 1-5 parts of a nucleating agent and 1-3 parts of a stabilizing agent. The temperature-regulation liner contacts with the head of a user to realize temperature regulation and is capable of releasing heat under a cold condition and absorbing heat under a scorching heat condition to enable a comfortable temperature for the head of the user.

Description

technical field [0001] The present invention relates to a temperature-regulating pad, and more particularly, to a temperature-regulating pad and a preparation method and application thereof. Background technique [0002] The helmet is mainly composed of a hard helmet shell, a cushioning layer and a flexible liner. Due to the particularity of the helmet's use environment, its cushioning material is generally made of low-density foam with a large thermal resistance and a certain thickness. The "sealed" protection of the helmet prevents the head from sweating and dissipating heat to a certain extent, which not only reduces the thermal comfort of the head, but also interferes with the wearer's sight to a certain extent, resulting in alarm Service personnel are reluctant to wear helmets, increasing the risk of injury. [0003] In order to solve the above problems, ventilated helmets or breathable helmets are usually used; ventilated helmets form air circulation through opening a...

AI Technical Summary

Problems solved by technology

The "sealed" protection of the helmet prevents the head from sweating and dissipating heat to a certain extent, which not only reduces the thermal comfort of the head, but also interferes with the wearer's sight to a certain extent, resulting in alarm Service workers are reluctant to wear helmets, increasing the risk of injury

[0003] In order to solve the above problems, ventilated helmets or breathable helmets are usually used; ventilated helmets form air circulation through opening air inlets and air outlets on the helmet shell, and take away heat for heat dissipation. This is also the current mainstream heat dissipation method for helmets , however, on the one hand, the air vent reduces the anti-riot performance of the anti-riot helmet, and on the other hand, it limits the use of the helmet in colder climates in winter; the ventilated helmet can effectively maintain ventilation by setting an open structure under the helmet shell, and the cold climate can also be closed by adding Environmental protection to keep warm

However, the addition of the closed ring body increases the production cost of the helmet, and the user needs to add the closed ring body by himself, which is more cumbersome to use

[0004] Whether it is a vent helmet or a breathable helmet, it only takes away heat without improving the comfort of the head. Therefore, there is an urgent need for a liner that can improve the comfort of the head and maintain a suitable temperature
