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

Embodiment 1

[0041] Lay the periphery of the upper and lower PVC composite fabrics, the straight line passing through the center of the circle, and the symmetrical curve together through high-frequency hot pressing (reserve a channel for phase change material filling); open a 30-degree gap in the inner hot-pressing compound gap of the circular temperature-regulating liner. vent holes;

[0042] Phase-change temperature-regulating material preparation: use 200 parts of sodium sulfate inorganic salt as a phase-change material, add 120 parts of water, stir at a speed of 40r / min for 60 minutes, then add 2 parts of glycerin, 2 parts of borax, 1 part of gelatin and 0.2 parts of chlorine NaCl, continue to stir at a speed of 40r / min until uniform and form a mixed solution. Heat the mixed solution to 80°C, let it basically melt, and set aside.

[0043] Pour the heat-absorbed mixed solution into the circular gasket with a reserved channel through a small funnel, and seal it with a high-frequency hea...

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...
