Earthquake protective clothing and production method thereof

Abstract

The invention relates to earthquake protective clothing particularly earthquake protection clothing and a production method thereof. The earthquake protection clothing attaches particular emphasis on the function of protecting personal safety of people at an earthquake critical moment. The finished clothing has high wearing comfortableness and high personal safety protection effectiveness. The method comprises the steps of selecting a fireproof outer layer fabric, using a high-strength and high-toughness reticular metal material for making a supporting skeleton and mechanically combining and assembling an impact fast-hardening material and an impact-resistant damping material into the protective clothing. The total thickness of the clothing is 10-15mm, the total weight is 2-4kg, the clothing can resist 300-400MPa external pressure after the finished clothing is put on, the impact toughness is 6-8J/cm<2>, the clothing is nonflammable at 120 DEG C and therefore the finished protective clothing has the functions of light weight, high flexibility, fire prevention, oppression resistance and impact resistance.

Description

technical field [0001] The invention relates to earthquake protective clothing, in particular to an earthquake protective clothing and a preparation method thereof, which pays special attention to the functionality of the product to protect personal safety in times of earthquake crisis, and the finished clothing has wearing comfort and high efficiency of personal protection. Background technique [0002] With the frequent activities in the earth's interior, earthquakes have become the main natural disasters that bring disasters to human beings. The "5.12 Wenchuan Earthquake" in 2008 and the "3.11 Japan Earthquake" in 2010 have caused different degrees of house building collapse and personal injury. Injuries not only brought huge economic losses, but also brought huge psychological harm, especially the physical disability caused by the collapse of buildings has become an indelible painful memory for those who experienced it in this life.

AI Technical Summary

Problems solved by technology

[0003] When the external environment changes drastically, such as fire, radiation, impact when buildings collapse, etc., ordinary cotton and chemical fiber clothing cannot resist these dangerous factors, and special clothing is required to protect the personal safety of users; Judging from the current development situation, firefighting clothing is a protective clothing with strong functions that people are familiar with. From the perspective of protection, the firefighting clothing currently in use has fire resistance, heat resistance and heat insulation. Outside the surface layer, there are water-proof layer, heat-insulating layer and flame-retardant comfortable lining, but it does not have the function of resisting the impact and compression of heavy objects, and cannot withstand the damage to the human body caused by the collapse of heavy objects during an earthquake; patent 02110886.2 provides "a kind of clothing A method of setting protection and a kind of partial protective clothing", that is, lining the clothing or setting protective materials to reduce the degree of damage when the user is attacked by a knife or gun, but it does not have the function of resisting heavy objects and impacts. Patent 96190827.0 provides "a kind of anti-impact protective clothing", which has many closed rings linked together to form an anti-impact protective layer inside the clothing, mainly to prevent nails from piercing through the rings, but the rings are under strong pressure and strong pressure. The impact is easily deformed, and the protective effect is weakened. Patent 89104293.8 (1989) provides an "inflatable shock-absorbing protective clothing for motorcycle drivers", which is mainly realized through gas regulators, trigger devices, and shock-absorbing pipes. Multi-parts are used in conjunction, the device is complicated, and it needs to be used in combination with the motorcycle body, so it is not suitable for protection during earthquake escape. Patent 97199807.8 provides "Use of polyether polyurethane for protective clothing", producing molded plastics from honeycomb to dense The manufactured protective clothing, especially the soles of protective boots, is not suitable for earthquake protection because the material is hard and not easy to bend.

[0004] The present invention aims to overcome the deficiencies of the existing protective clothing in the functions of "light weight, flexibility, fire prevention, compression resistance, and impact resistance", and provides an earthquake protective clothing for the integration requirements of the above functions. Materials and preparation methods. The material used in the protective clothing has high tensile strength and compressive strength, and can not deform or break under a certain intensity of impact or pressure, and protect the user's limbs from injury. The selected material is a composite of high-strength metal material and high-quality damping material. From the design of the garment, we pay attention to the comfort of wearing. The weight of the garment is light, otherwise it will affect the rapid movement of people when disaster strikes. The design is 2~4kg, with special emphasis on the chest , the protection of the head, and the flexibility design of the joint position of the arms and legs

At the same time, when an earthquake occurs, it is easy to cause gas pipelines to burst and leak, which can easily cause fires. Therefore, protective clothing is required to have a certain fireproof function.
