(3)Treating products with microwaves and 8~10 parts of tetramethoxy-silicane, 2~4 parts of epoxidized soybean oil excessively are added to mixer jointly
In, mixer internal temperature is improved to 180~190 DEG C, at such a temperature internal mixing and plasticizing 40~60 minutes, is then added anti-quiet
0.5~1.5 part of electric agent improves mixer internal temperature to 250 DEG C, and secondary internal mixing and plasticizing 20~30 minutes obtains secondary close
It refines product and heats and maintain molten condition;
(4)15~25 parts of molecule distillating monoglyceride, 5~9 parts of ethoxylated alkylamine are mixed and heated to molten condition, by itself plus
Maintaining temperature in the secondary mixing product for entering to be similarly molten condition, after being uniformly mixed keeps mixture in molten state
In the range of, it is filled with 1~2 part of physical blowing agent into molten mixture, molten mixture is made fully to foam;
(5)Molten mixture after foaming is injected in extruder while hot, sets extruder temperature as 150 DEG C, screw speed is
80~100 revs/min, extruder pressure is 50 MPa, and modified pearl cotton material is obtained after extruded, cooling, packaging.
2. thermal-insulating type modified pearl cotton material preparation method according to claim 1, which is characterized in that the step(1)
Middle mixed material is preferably stirred to react 25~35 minutes with 200~300 revs/min of rate in a kettle.
3. thermal-insulating type modified pearl cotton material preparation method according to claim 1, which is characterized in that the step(2)
The microwave frequency of middle microwave treatment is 280~300 MHz, and processing time is 15~25 minutes.
4. thermal-insulating type modified pearl cotton material preparation method according to claim 1, which is characterized in that the step(3)
In antistatic agent it is arbitrary in cationic antistatic agent, anionic antistatic agent and non-ionic antistatic agent
It is a kind of.
5. thermal-insulating type modified pearl cotton material preparation method according to claim 1, which is characterized in that the step(4)
In any one in butane, hexane and carbon dioxide of physical blowing agent.
6. according to thermal-insulating type modified pearl cotton material made from any one of the claim 1-5 preparation methods as packaging material
Application.
