A2, emulsion polymerization：Polymeric kettle nitrogen charging is vacuumized first, then puts into deionized water, the fourth two of formula ratio in A1
Alkene, acrylonitrile, methacrylic acid, surfactant, electrolyte, pH buffer, chain-transferring agent, initiator are started to warm up to 25
~35 DEG C, and 7~8h of polymerisation, the miniemulsion of the stabilization of 100~500nm is formed, then starts to add response type for the first time
Emulsifier, and when being continuously heating to 36~40 DEG C, react 3~5 hours, add reactive emulsifier for the second time later and finally heat up
It to 50~60 DEG C, reacts 3~5 hours, when conversion ratio reaches more than 98%, stops reaction；
A3, degassing process：The reactant obtained in A2 is de-gassed processing by degassing tower, unreacted monomer is removed, adds
Enter lye and adjust pH value between 7~8, cooling discharge obtains Novel acrylonitrile butadiene rubber breast.
3. the preparation process of novel butyronitrile gloves according to claim 2, it is characterised in that：The emulsifier is vinyl
Sodium sulfonate, allyloxy hydroxypropyl azochlorosulfonate acid sodium, allyloxy Nonylphenoxy propyl alcohol, polyoxyethylene ether ammonium sulfate and metering system
The mixture of one or more of sour hydroxypropyl azochlorosulfonate acid sodium.
4. a kind of preparation process of novel butyronitrile gloves according to claim 2, it is characterised in that：The chain-transferring agent is
The composition of tert-dodecyl mercaptan, dodecyl mercaptan carbon or both.
5. the preparation process of novel butyronitrile gloves according to claim 2, it is characterised in that：The pH buffer is：Carbon
The combination of one or more of hydrochlorate, phosphate and pyrophosphate.
6. the preparation process of novel butyronitrile gloves according to claim 1, it is characterised in that：The antistatic agent is poly- second
Alkene, Ethylene Glycol Methyl acrylic copolymer, polyether ester amides, polyether ester acetamide, polyethylene glycol oxide, epoxypropane copolymerization object
In one or several kinds of combinations.
7. the preparation process of novel butyronitrile gloves according to claim 1, it is characterised in that：In the coagulant solution
CaCl2Mass fraction be 7%~13%, CaCO3Mass fraction be 10%~20%.
