Embodiment 1
[0041] A corrosion-resistant plastic, made of the following raw materials in parts by weight: 80 parts of polyvinyl chloride, 5 parts of corrosion-resistant filler, 1 part of cadmium stearate, 3 parts of diethyl phthalate, and 3 parts of heat stabilizer;
[0042] The corrosion-resistant plastic is made by the following steps:
[0043] Step S1: Stir the polyvinyl chloride and cadmium stearate for 10 minutes at a rotating speed of 300 r / min to obtain the first mixture;
[0044] Step S2: Stir the corrosion-resistant filler and heat stabilizer at a rotational speed of 500 r / min for 3 minutes, then add diethyl phthalate, and continue stirring for 10 minutes to obtain a second mixture;
[0045] Step S3: melting and stirring the first mixture and the second mixture for 30 minutes under the conditions of a rotation speed of 1000 r / min and a temperature of 170° C. to obtain a molten material;
[0046] Step S4: Put the molten material into a three-stage twin-screw extruder, extrude and...
