Description
Technical Field
The invention relates to the technical field of fireproof products, in particular to a hydrogel fireproof headgear capable of blocking smoke.
background
In social life, fire disasters are a multiple disaster which threatens public safety and endangers lives and properties of people. According to statistics, about 1 ten thousand fires occur every day in the world, 2000 deaths occur, 3000 + 4000 people are injured, and the direct property loss caused by the fires every year reaches more than 10 billion yuan. Especially, the extremely serious fire which can directly cause the death of dozens of people and hundreds of people at one time continuously happens, and huge loss is caused to the lives and properties of the nation and the people.
currently, the leading causes of fire death can be divided into 5 categories: (1) suffocation death by inhalation of toxic smoke, (2) direct burning by fire, (3) crowd death of people, (4) death due to incorrect escape mode, and (5) excessive death by frightening. The information shows that the casualties caused by oxygen deficiency and smoke invasion in the fire occupy 50 to 80 percent of the total death population in the fire.
the smoke has great harm to human body, and because the complexing action of gases such as carbon monoxide, carbon dioxide, hydrogen cyanide and the like and hemoglobin of the human body is strong, the oxygen loses the complexing action with the hemoglobin, and people die due to oxygen deficiency. Chemical suffocation death occurs after inhalation of carbon monoxide, hydrogen sulfide and cyanide. The affinity of carbon monoxide to hemoglobin is 210 times greater than that of oxygen, and when the carbon monoxide content in the air reaches 0.1%, 50% carboxyhemoglobin and 50% oxyhemoglobin are formed in the blood, causing severe poisoning of carbon monoxide, wherein when the carbon monoxide concentration reaches 1.28%, a person dies within 3 minutes in such an environment. The oxygen content in the smoke in a few minutes in a fire scene is far lower than 21 percent, the carbon monoxide content is far higher than 0.1 percent, and people can die in a short time; cyanide has strong cytotoxic effect, and can be rapidly combined with cytochrome oxidase to generate ferricyanide cytochrome oxidase after entering into the body, so that cytochrome loses the capability of transferring electrons, respiratory chain is interrupted, cells die, and people are suffocated and die.
In recent years, various fireproof and flame-resistant products are widely used in various aspects of the present society, such as: the purpose of developing these materials is to block fire and high temperature, strive for the gold time of escape and rescue, and protect the safety of personnel and property. The most common fireproof product can be directly made of a flame-retardant material, or a layer of fireproof coating is coated on the surface of the product to form a protective layer, so that the flame-retardant effect of the product is improved. However, fire-fighting clothing is not readily available for persons waiting for rescue, and although fire-proof panels, fire-proof doors, etc. of buildings can resist high temperature for a certain period of time, if the fire source is not extinguished as soon as possible, and the fire is burned for too long, the fire may be damaged. How to make the survival rate of the personnel trapped in the fire scene be improved in the fire state, and even make the fire fighter performing the rescue task in the fire scene reduce the probability of being burned and scalded by fire is the subject to be achieved in the industry.
Fire protection is one of important equipment for protecting the personal safety of firefighters who are active in the first line of fire protection, and is not only an indispensable necessity for a fire rescue scene, but also a fire protection tool for protecting the bodies of firefighters from injury. Therefore, various kinds of fire-proof clothes, fire-proof blankets, and fire-proof head covers of various materials and styles have been developed, but they all have certain disadvantages. Traditional fire prevention clothing can effectually prevent the ignition of big fire, has high insurance coefficient, but the clothing body is heavy, wear consuming time, and this best opportunity that may miss fleeing, and this kind of fire prevention clothing thermal diffusivity is poor simultaneously, very easily lets the people produce sultriness under high temperature environment, may lead to low limbs vasodilatation, and the blood silts, and takes place to faint. In addition, such fire-proof clothes are expensive and not beneficial to popularization and use. The fire blanket is simple effective in the face of small-size conflagration, but the coefficient of safety is lower in the actual scene of a fire escape and death process, can not play effectual protection. The fireproof headgear can effectively protect the head of a person from being burnt, is convenient to wear, and has higher practical significance in the actual escape process. However, most of the existing fireproof headgear have no functions of preventing smoke and filtering toxic gas. Therefore, the development of novel light, smoke-proof and poison-proof heat insulation has higher practical significance, and casualties caused by fire disasters can be reduced.
the hydrogel material has a cross-linked reticular cross-linked molecular network structure, the hydrogel material has large water absorption capacity, strong water retention capacity and good compactness, and the hydrogel heat insulation pad has good water retention and heat insulation even under the heating condition, so that the hydrogel material has unique advantages in the heat insulation aspect. Patent (CN 101560300 a) discloses a super absorbent resin gel capable of blocking heat source prepared by using super absorbent resin and fiber cloth as main materials, which can store a large amount of water in the super absorbent resin after the fire-proof clothing contacts water source, so that the material has excellent heat-insulating and fire-proof effects, but there are two problems with this kind of material: (1) before use, the water-saving escape capsule needs to be soaked in water for a period of time and then used, so that the optimal escape time is lost; (2) the fire-proof clothes can not effectively prevent the smoke from damaging the human body, and the smoke enters the respiratory tract of the human body along the upper ventilation part, thereby causing casualties. Especially, the second problem is that if the problem is not solved well, the development of the current materials such as fire-proof clothes is difficult to be promoted, and the personal safety of the personnel trapped in the fire scene cannot be guaranteed comprehensively.
