S1: firstly, putting a silicon rubber raw material into a stirring kettle (3) manually, pushing a shell (2) to the lower side of a platform (1), and enabling the shell (2) and the platform (1) to form a closed space;
s2: stirring and mixing, namely stirring and mixing the silicon rubber raw materials through stirring blades (105) to uniformly mix the raw materials;
s3: the method comprises the steps of primarily eliminating bubbles, pumping air in a shell (2) through a vacuum pump (101), forming a negative pressure state in the shell (2), and further enabling bubbles in the silicon rubber to float upwards and be pumped to the outside, and primarily eliminating the bubbles in the silicon rubber;
S4: the bubble is eliminated to degree of depth, makes the silicone rubber continuously gush up through auger (103) rotation, makes the bubble elimination rate of silicone rubber downside accelerate, prolongs the detention time of silicone rubber through retarder (201), further improves the bubble elimination effect, effectively avoids the bubble to produce harmful effect to the silicone rubber quality.
