Description
Technical field
The present invention relates to safety and industrial gloves technical field more particularly to a kind of arc resistant butyronitrile gloves and its production methods.
Background technique
Electric arc is a kind of gas discharge phenomenon, and electric current passes through moment spark caused by certain dielectrics (such as air).
Currently, building, machine-building, welding equipment and brazing equipment manufacture, electrical equipment manufacture, means of transport manufacture and maintenance and
The industries such as maintenance can generate electric arc.When electric arc occurs, huge energy can be discharged in the extremely short time.The harm of electric arc is main
There is the following aspects: burn, damage hearing, eyesight and respiratory system etc..
Arc stiffness is described by electric arc magnitude (ATPV, Arc Thermal Performance value).Electric arc magnitude
Unit be Cal/cm2(calorie every square centimeter)；It refers to the gross energy on a unit area, for detecting electric arc
Intensity.1Cal/cm2Exposure energy be equivalent to cigarette butt that one is lighted 1 second on finger tip, as long as 1-2Cal/cm2It will make
The skin of people causes 2 grades to burn.According to NFPA association of the U.S., learning electric arc wound after all is mainly what electric arc explosion time generated
Huge thermal energy leads to the burn of human body, so, measuring electric arc may bring the classification standard of injury to usually use arc energy
Standard, i.e. Cal/cm2(calorie every square centimeter).The ATPV value of arc resistant butyronitrile gloves is bigger, illustrates its arc resistance energy
Better.
According to incompletely statistics, just there is a pair of hand injury accident within average every 32 seconds in the world, especially in electric arc
In operating process, wearing arc resistant butyronitrile gloves can about reduce by 70% hand injury.It can be seen that suitable arc resistant fourth
Nitrile gloves importance can not look down upon.
Therefore, how to be directed to disadvantage present in the above-mentioned prior art and carry out research and development improvement, actually exerted needed for relevant industry
Power research and development target, the application designer in view of this, be think and creation idea, designed then with the experience of many years, pass through
In many ways sampling test is inquired into and is studied, and repeatedly amendment improvement, be releasing the application.
Such as application No. is 201510936445.5 Chinese invention patents to disclose a kind of life of arc resistant butyronitrile gloves
Production method comprises the following steps that the preparation of a, arc resistant latex: firstly, the ratio for being 1:1 according to weight ratio by arc resistant powder and water
Example mixing, ball milling 40-50 hours obtained arc resistant slurries；Then it selects carboxy nitrile rubber to be added in arc resistant slurry to be configured to
Arc resistant butyronitrile latex；The component of the arc resistant powder is as follows in parts by weight: 20-40 parts of ammonium polyphosphate of 10-30 parts of red phosphorus
10-20 parts of aluminium hydroxide.But the technique only improves arc resistant by the way that red phosphorus, ammonium polyphosphate etc. are added in NBR latex
Property, arc resistant effect is poor, is unable to satisfy requirement of the glove industry to gloves arc resistance energy.
For another example application No. is 201720037656.X Chinese utility model patents to disclose a kind of fire-retardant arc resistant safety hand
Set, including glove bulk, the glove bulk use the five fingers separate type, and it is fire-retardant outer that glove bulk is followed successively by anti-burst from outside to inside
Layer, thermal protection layer, phase change layer, insulating layer are set in phase change layer, and insulating layer is matched with glove bulk shape, glove bulk
Refer to that conjoined structure, four finger conjoined structures are connected by fire retardant insulating zipper with glove bulk equipped with four, the glove bulk outer layer palm of the hand
Position is equipped with Antiskid flame-proof rubber bump.But the technical approach on glove bulk by being provided with multiple functional layers, essence
The superposition of only multiple functional layers is only capable of playing the injury for reducing electric arc when electric arc generates, can not really avoid electric arc pair
The injury of operator's hand, and the gloves are provided with multiple functional layers, more thick and heavy, wearing is inconvenient.
Application No. is 201720663801.5 Chinese utility model patents to disclose a kind of arc resistant insulating glove, including hand
Cover ontology, to interior and be disposed with basal layer, anti-puncture layer and arc resistant layer outside, the basal layer is the glove bulk
Acetate fiber looped fabric, the anti-puncture layer are fiberglass gridding cloth, and the arc resistant layer is insulation epidermis, the substrate
It is connected between layer, anti-puncture layer and arc resistant layer adjacent layer using adhesive.But the technical solution is also by gloves sheet
Multiple functional layers are set on body, and essence is only the superposition of multiple functional layers, is only capable of playing when electric arc generates and reduces electric arc
Injury can not really avoid injury of the electric arc to operator's hand, and multiple functional layers are arranged in the gloves, more thick and heavy,
Wearing is inconvenient not flexible.
To sum up, it is necessary to which designing a kind of can be avoided, reduce in electric arc operating process electric arc to the wound of operator's hand
Evil, arc resistant is functional, and flame retardant effect is good, dresses light, flexible, the arc resistant butyronitrile hand of good permeability and health environment-friendly
Set and its production method.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide one kind can be avoided, reduces in electric arc operating process
Injury of the electric arc to operator's hand, arc resistant is functional, and flame retardant effect is good, dress it is light, flexible, good permeability and

When arc burning glove surface, the humidity on local material surface is significantly improved, and modified aluminium hydroxide is being heated to
220 DEG C or so can decomposite rapidly the crystallization water and absorb a large amount of heat, to reduce the temperature of material surface.Aluminium hydroxide
The free carbon that the crystallization water decomposited generates when can decompose with latex under the catalytic action of aluminum oxide reacts, and produces
The carbon monoxide and carbon dioxide of volatilization prevent the formation in conductive charing channel.
When modified magnesium hydroxide is heated under conditions of 340 DEG C -490 DEG C, it may occur that decompose the heat for absorbing comburant surface
Amount, to play fire-retardant effect.Meanwhile the oxygen on a large amount of moisture dilute combustion object surface can be also released, it decomposes and generates
Activated magnesia can be attached to the surface of combustible, further prevent the progress of burning.Secondly, modified magnesium hydroxide is whole
It is a it is fire-retardant during will not only generate any harmful substance, but also the product that decomposes of modified magnesium hydroxide play it is fire-retardant
While effect, the smog and pernicious gas of the burnings such as latex generation can also be largely absorbed, activated magnesia can constantly be inhaled
Imperfect combustion fusing residue is received, and then stops burning quickly, and eliminates smog and prevents molten drop.
The thermal degradation products of tributyl phosphate promote latex surface rapid dehydration and carbonize, and then form charring layer.Due to
Combustion by evaporation and decomposition combustion of the simple substance carbon without generating flame；In addition, tributyl phosphate decomposes generation under ignition temperature
Nonvolatile glassy mass is coated on latex surface and forms fine and close protective layer, plays the role of isolation.
