The invention belongs to the technical field of organic chemical industries and provides a method for preventing sticking of chlorosulfonated polyethylene colloidal particles. The method includes the following steps that firstly, an extruding system is started, and a hopper is filled with calcium stearate; secondly, a calcium stearate lubricating agent is added into a particle dicing box, the adding time of the calcium stearate lubricating agent is controlled through air source blowing-in pressure adjusted by an instrument air pressure reducing valve and configuration of a logic block of a DCS; thirdly, the air blowing time of the DCS is set to be 1 s, and the air blowing interval time is prolonged to 40 s; and fourthly, the particle dicing box is detected, a box body is filled with the calcium stearate lubricating agent which is in contact with particle materials, and therefore the sticking-preventing chlorosulfonated polyethylene colloidal particles are manufactured. The method has the beneficial effects that calcium stearate is automatically conveyed and controlled in a timing manner through configuration of the logic block of the DCS; synchronization of air blowing and hopper vibrating feeding is achieved, and the problem of blocking of the discharged calcium stearate is effectively solved; and the air blowing power is adjustable so as to adapt to sticking preventing control over the colloidal particles different in viscosity, and the scrap colloid rate of products is reduced to 0.4%.
