Continuous ultrasonic-assisted rubber film calendering device and rubber film preparation method thereof

Abstract

The invention provides a continuous ultrasonic-assisted rubber film calendering device and a rubber film preparation method thereof. The rubber film calendering device comprises a primary mixing stirring tank, a fine mixing ultrasonic stirring tank set, an intelligent control system, a constant-temperature refrigerating device, an internal mixer, a conveying belt, a calendering machine, a cooling roller, a tensioner and a center coiling machine. The fine mixing ultrasonic stirring tank set comprises two fine mixing ultrasonic stirring tanks arranged in parallel, the primary mixing stirring tank is communicated with the two fine mixing ultrasonic stirring tanks through a primary mixing discharging pipeline, the two fine mixing ultrasonic stirring tanks are communicated with the constant-temperature refrigerating device, and the constant-temperature refrigerating device is communicated with the internal mixer. The internal mixer conveys refined materials to the calendering machine through the conveying belt to be calendered into the rubber film, and the rubber film is cooled by the cooling roller and tensioned by the tensioner and then is wound by the center coiling machine. The intelligent control system controls the temperatures in the fine mixing ultrasonic stirring tanks, the material particle size dispersion condition and automatic feeding and discharging. The filler is uniformly dispersed in matrix resin, the rubber film quality is good, and continuous production is realized.

Description

technical field [0001] The invention belongs to the technical field of film preparation, and in particular relates to a continuous ultrasonic-assisted calendering film device and a film preparation method thereof. Background technique [0002] Adhesive films are widely used in high-precision, high-resolution spacecraft optical load structures and other related industries. Adding different fillers in the film production can realize the film with different functions, such as thermal conductive, conductive, high temperature resistant film. However, the current production process of the film with fillers is mainly to artificially evaluate whether the fillers are uniformly dispersed in the main resin after simple stirring, and then enter the rubber mixer for refining and then use the calendering device to form a film by calendering; in this process , due to insufficient reserved mixing time in the pipeline, the dispersion of the filler in the main matrix resin is not uniform eno...

However, the current production process of the film with fillers is mainly to artificially evaluate whether the fillers are uniformly dispersed in the main resin after simple stirring, and then enter the rubber mixer for refining and then use the calendering device to form a film by calendering; in this process , due to insufficient reserved mixing time in the pipeline, the dispersion of the filler in the main matrix resin is not uniform enough, which seriously affects the production quality and functionality of the film, and cannot achieve the purpose of continuous production
