Abstract
The invention provides a multifunctional nuclear radiation protective garment and relates to the technical field of nuclear radiation protection. An outer layer is a protective layer capable of achieving the inflaming retarding function, the waterproof function and the antifouling function. A middle layer is woven cloth woven from composite cellosilk and is capable of achieving the nuclear radiation protection function. An inner layer is a fabric layer made of polyamide fibers or polyester fibers or cotton fibers. The multifunctional nuclear radiation protective garment has the excellent nuclear radiation protection performance and good flexible nuclear comfort. The multifunctional nuclear radiation protective garment has the remarkable advantages of being light, thin, capable of being bent in the use process, long in service life and capable of avoiding nuclear penetration caused by the fact that a material is bent to breakage. The multifunctional nuclear radiation protective garment can be widely applied to daily radiation protection and nuclear emergency protection in the fields of nuclear power plants, hospitals, military nuclear devices and the like.
Description
Technical field
The present invention relates to nuclear radiation protection technical field, especially the production technology of nuclear radiation protection clothes.
Background technology
Nuclear science technology has been widely used in multiple fields such as national defence, the energy, industry, medical treatment, bring huge economic and social benefit, also increased the chance that people contact various radiation and are subject to its threat, nuclear and radiation safety problem is outstanding day by day and receive much concern.Radiation protection material is the key that guarantees radiation place staff and public security with equipment, is also the effective means of dissolving nuclear accident crisis, is the important leverage of military and civilian radiological safety protection, has active demand.
Because lead has good nuclear radiation protection effect and lower cost, be widely applied in nuclear radiation protection field.Stereotype, lead brick etc. generally provide stationary radiation protection as protection body of wall or nuclear facilities main body, do not possess movability.Lead shield, stereotype, lead glass etc. also can be applied to moving protection body maybe needs to provide the place of temporary transient protection, but radiation leakage has a big risk, builds, difficulty is high, utilization factor is low, suitable type is poor.Take lead powder rubber as main flexible protective screen, protective clothing etc., possess mobile and detachability strong, the advantage of good leak tightness, but protection efficiency low (linear attenuation coefficient is little), poor stability (matrix easily aging, lead powder easily comes off), recycling rate of waterused are low (repeatedly after folding use, folding line place is damaged), use cost high (for guaranteeing the validity of protection, need frequently change).Publication number is CN101885059 Chinese invention patent, discloses a kind of preparation method of plumbous short fibre, can realize the serialization of plumbous short fibre and produce.Publication number is the Chinese invention patent of CN 102222530, the production method of utilizing lead fiber silk to prepare nuclear-radiation shielding lead garment is disclosed, have advantages of that radiation protection efficiency is higher compared with the plumbous clothing of the plumbous rubber of tradition, press and rubber curing forming because staple fibre can only adopt to prolong, cause its stability and comfortableness to have much room for improvement.
Summary of the invention
The object of the invention is to propose a kind of multifunctional core radiation protection light, thin, that protection effect is good takes.
Technical solution of the present invention is: the protective seam of outer, waterproof fire-retardant for having and anti-pollution function, and middle layer is to have the composition fiber silk of nuclear radiation protection function by the woven fabric of woven formation, internal layer is polyamide fibre, dacron or cotton fiber precoat.
Protective clothing of the present invention has the multilayer flexible material composition of difference in functionality, there is excellent nuclear radiation protection performance, have anti-electromagnetic radiation and anti-static electrification concurrently simultaneously, possess fire-retardant, grease proofing, anti-puncture, anti-cutting, the several functions such as shellproof, possess good flexible core comfortableness, can be widely used in daily radiation protection and the nuclear emergency protection in the fields such as nuclear power station, hospital, military nuclear armament.Its outstanding feature is: light, thin, tear open curvedly taking not to be afraid of in process, long service life, has avoided being curvedly directed at the core that Materials Fracture occurs and penetrating because tearing open.
In addition, the composition fiber silk with nuclear radiation protection function of the present invention comprises the metal fiber wire inner core with nuclear radiation protection function, weaves at least one deck be outward cancellated clad at described metal fiber wire inner core.
The described metal fiber wire inner core with nuclear radiation protection function is at least one metal fiber wire, described metal fiber wire be in lead fiber silk, lead alloy filament, tungalloy filament or tantalum alloy filament at least any one.
Braiding clad material be in carbon fiber, hdpe fiber, polytetrafluoroethylene fibre, polyphenylene sulfide fibre, polyamide fibre, dacron or polyimide fiber at least any one.
In order further to improve anti-nuclear radiation of the present invention, anti-electromagnetic radiation, to prevent wearing cutting and anti-puncture property, middle layer of the present invention comprises at least both woven cloth.
Described protective seam is through the high density polyethylene cloth of grease proofing, waterproof, fire-retardant strengthening or polyimide cloth or TPU cloth.Can improve the functional requirement such as the resistance to soiling of protective clothing and the refractability of special occasions.
