Embodiment 1
[0041] A) preparation of natural rubber latex for impregnation
[0042] First with 100 parts by weight of natural rubber latex (in terms of dry rubber), 0.5 parts by weight of sulfur, 0.5 parts by weight of zinc oxide, 0.4 parts by weight of rubber accelerator ZDC, 0.2 parts by weight of rubber accelerator ZMBT and 1 part by weight of rubber antioxidant BHT well mixed;
[0043] Add 150 parts by weight of bismuth oxide into 145 parts by weight of water and dispersant N of 5 parts by weight, and stir at room temperature for 1 hour to obtain a dispersion of the radiation-proof material;
[0044] Slowly add the prepared bismuth oxide dispersion into the prepared natural rubber latex mixture under constant stirring; adjust the solid content of the rubber latex to 50%, to obtain the natural rubber latex for impregnation;
[0045] B) the mold is first dipped into a coagulant-16wt% calcium chloride aqueous solution, and then dried at 120° C. for 2 minutes;
[0046] C) dipping the na...
Embodiment 2
[0051] A) Neoprene latex for preparation of dipping
[0052] First 100 parts by weight of chloroprene rubber latex (in terms of dry rubber), 1 part by weight of sulfur, 5 parts by weight of zinc oxide, 1 part by weight of rubber accelerator BZ and 1.2 parts by weight of WingStay L rubber antioxidant are mixed uniformly;
[0053] Then the lead oxide of 130 parts by weight is added in the dispersant N of 127 parts by weight of water and 3 parts by weight, stirred at room temperature for 1 hour, to obtain the dispersion liquid of radiation protection material;
[0054] Under constant stirring, slowly add the prepared lead oxide dispersion into the prepared neoprene latex mixture; adjust the solid content of the rubber latex to 35%, to obtain the neoprene latex for impregnation;
[0055] B) the mold is first dipped into a coagulant-25wt% calcium nitrate aqueous solution, and then dried at 120° C. for 2 minutes;
[0056] C) dipping neoprene latex again, immersing for 15 seconds; ...
