Problems solved by technology

The mixing effect of a single extruder is poor, and the plastic phase and the rubber phase cannot form a uniform "sea island structure", which makes the product less stable; the linkage between the internal mixer and the extruder solves the mixing problem to a certain extent, but the process is relatively Difficult to control, unable to produce continuously, poor real-time monitoring ability

Abstract

The invention discloses a preparation method of a dynamically-vulcanized rubber waterproof roll. Two twin-screw extruders are linked, and the parameters of the twin-screw extruder sare controlled strictly, so that the production process of the dynamically-vulcanized rubber waterproof roller is high in cutoff ability. Different phases are uniformly mixed, so that a uniform 'island structure' can beformed. The dosages of the components are adjusted reasonably, so that the prepared product has superior physicochemical performance and high quality stability. Moreover, continuous production can berealized, real-time monitoring of the product quality is realized, the production efficiency of the production process is improved greatly, the process and formula can be adjusted online in real time, and the rejection rate is lowered.

Description

technical field [0001] The invention relates to the field of waterproof coiled material, in particular, the invention relates to a preparation method of a dynamic vulcanized rubber waterproof coiled material. Background technique [0002] With the vigorous development of the construction industry, the demand for waterproof membranes in the field of construction engineering is also increasing. Similarly, the requirements for material quality are also improving, thus providing a broad space for the promotion and application of new polymer membranes. At present, domestic More mature polymer membranes mainly include EPDM vulcanized membranes and polyvinyl chloride (PVC) waterproof membranes. Polyvinyl chloride waterproof membrane can be produced continuously, but the membrane is not resistant to aging and has poor durability. At the same time, phthalic acid plasticizers are often added in the production of PVC waterproof membrane, which is harmful to the human body and the envir...
