Between, test result is as shown in table 1 below.
The test of the resistance of butyronitrile gloves, cleanliness factor, tensile strength, elongation at break and cure time in the embodiment of table 1
Value
As shown in Table 1, do not add the butyronitrile gloves resistance value of antistatic additive very big, such as comparative example 2 and comparative example 4, antistatic
Poor performance；And select common anti-static liquid as antistatic additive, such as comparative example 4 ', Jing after 5 ultra-clean cleanings, resistance still compared with
Greatly, antistatic effect is poor；The antistatic butyronitrile gloves of present invention resistance Jing after 5 ultra-clean washings is less, is still maintained at 106~
108Between Ω, its antistatic property is illustrated preferably, and washing fastness is good, this is because the imidazole salt ion that the present invention is selected
, in butyronitrile gloves formative stage, there is vulcanization crosslinking between butyronitrile latex and react the network structure to form crosslinking in antistatic additive,
These network structures can eliminate passage as electric charge, so as to reduce resistance；And the cross-bond for being formed is prevented from antistatic
Agent is migrated, it is ensured that antistatic additive stable dispersion in butyronitrile gloves, makes butyronitrile gloves possess permanent antistatic effect, and Jing is more
After secondary ultra-clean washing, resistance value is still relatively low.
Can also be learnt by data in table, in the butyronitrile latex using same concentrations, the liquid of butyronitrile gloves of the present invention is sent out
Dust quantity and ion concentration are relatively low, illustrate that butyronitrile gloves cleanliness factor of the present invention is higher, this is because the antistatic butyronitrile handss of the present invention
Set surface is difficult stored charge, is difficult to adsorb dust, at the same in inventive formulation each COMPONENTS COMPATIBILITY preferably, the grit for coming off compared with
It is few.Titanium dioxide is added in the present invention, can play a part of to brighten, be alternatively arranged as carrier, be effectively facilitated vulcanizing agent, promote
Enter the dispersibility and stability of agent and catalyst in butyronitrile latex, further improve the cleanliness factor of butyronitrile gloves.In addition, this
Antistatic additive in bright improves curing efficiency, reduces cure time, enhances tensile strength, this is because the miaow of the present invention
Azole ionic liquid antistatic additive can improve the activation capacity of accelerator, promote catalyst to make with the interface cohesion of butyronitrile latex
With, the vulcanization crosslinking speed of butyronitrile latex and butyronitrile latex and antistatic additive is accelerated, curing efficiency and crosslink density are improve,
Made butyronitrile gloves antistatic property is good, and persistently, tensile strength is big for antistatic effect.
