preparation example Construction
[0031] A method for preparing an X-ray shielding film, comprising the following steps:
[0032] Step 1) mixing natural rubber layer, styrene-butadiene synthetic rubber, anti-aging agent, accelerator, sulfur, release agent and lead powder into lead rubber layer by two-roll rubber mixing machine;
[0033] Step 2) mixing the natural rubber layer, styrene-butadiene synthetic rubber, anti-aging agent, accelerator, sulfur, release agent and carbon black into a wear-resistant rubber layer by a two-roller rubber mixer;
[0034] Step 3) stretching the product obtained in step 1 and step 2 through the pressure of a three-roll calender to form a sheet;
[0035] Step 4) Heat the lead rubber layer, reinforcing fabric layer, and protective layer through a flat carding machine, pressurize the carding machine, set the heating temperature to 140-145 ° C, and the heating time is 20 minutes;
[0036] Step 5) Punching the pieces;
[0037] Step 6) Verify the installation.
