Abstract
The invention discloses an oil-resistant silicone sealant production process comprising the steps that: (1) 150-160 parts by weight of silicone resin,280-290 parts by weight of lightweight calcium carbonate, 10-13 parts by weight of titanium dioxide, and 2-4 parts by weight of white carbon black are mixed in to a mixer; (2) the mixed material is transferred to a three-roll mill and is grinded, wherein a temperature is controlled at 30 DEG C; (3) the grinded material is transferred into a reaction kettle through a material transfer tank, such that water content in the material is removed; a stirring device in the reaction kettle is started, and stirring is carried out; reaction kettle jacket electric heating rods start to heat; when a heating temperature reaches 90 DEG C, a vacuum pump is started, and vacuum dehydration is carried out; when dehydration is finished, the material is naturally cooled; and (4) after natural cooling, the material is transferred to a blending and filling machine in a packaging workshop through a transfer tank; 40-43 parts by weight of a coupling agent KH-550 is directly added by using a galvanized iron tank; and the material is well mixed by stirring under a sealed condition, such that a finished product is obtained. With the oil-resistant silicone sealant production process, the prepared oil-resistant silicone sealant has the advantages of no toxicity, no workpiece corrosion, and good oil resistance.
