Embodiment 1
[0026] Example 1 A field controller casing, which includes the following raw materials in parts by mass (kg): 200 parts of ABS resin; 100 parts of PVC resin; 0.3 parts of carbon black-titanium dioxide mixture; 2.0 parts of plasticizer ESO; ultraviolet light Absorbent 1.5 parts; ZnSt 2.0 parts; CaSt 2.0 parts; organotin carboxylate 2.0 parts; antioxidant 1.0 parts.
[0027] The preparation method of the field controller shell comprises the following steps:
[0028] (1) Weigh each raw material according to the ratio;
[0029] ⑵Put PVC resin, carbon black-titanium dioxide mixture, plasticizer ESO, and organic tin carboxylate into the hot mixing pot and stir evenly at a speed of 700r / min and heat the mixture. When the temperature reaches 90°C, add ZnSt and CaSt Continue heating and mixing, when the temperature rises to 110°C, put it into the cold mixing pot for cold stirring, and when the temperature drops to 45°C, unload;
[0030] (3) Put the material obtained in step (2) into ...
Embodiment 2
