Embodiment
A kind of preparation process of antistatic organic glass is present embodiments provided, the preparation process successively includes following step
It is rapid:
The first step, the preparation of pre-polymerization slurry:
Major ingredient methyl methacrylate is injected in heating kettle, stirs in addition, azo two is added in whipping process
The composite initiator system of different heptonitrile and azodiisobutyronitrile is heated to 80 DEG C of heat preservation 20min, is heated to 100 DEG C later, protects
Boiling 20-30min is held, it is spare after determining that material viscosity reaches 40-60s using -4 glasss of measurements of painting；
Second step adds antistatic agent:
Antistatic agent, dimethylaminoethyl methacrylate, methyl are added into the intermediate product obtained through above-mentioned steps
Acrylic acid cools down after mixing, obtains spare slurry；
Third step fills mould:
Filling mould is carried out after spare slurries filtration in organic glass particular manufacturing craft, mold process is filled and is applied using acrylic board sizing
Pressure device ensures that plate thickness is uniform；
4th step, low temperature polymerization:
It is filled the mold that mould is completed to be placed in cage vehicle, is transferred cage vehicle into 45-65 DEG C of constant temperature pool by row loop wheel machine structure
It is totally submerged, Immersion time 3-6h, carries out low temperature polymerization；
5th step, high temperature polymerization:
After the completion of low temperature polymerization, cage vehicle is hung out from pond, is pushed into 105-120 DEG C of high temperature furnace high temperature and polymerize 2-10h；
6th step, cool down demoulding:
