Problems solved by technology

The mixing effect of a single extruder is poor, and the plastic phase and 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, not continuous production, poor real-time monitoring ability, and most of the existing rubbers have poor flame retardant effect

Abstract

The invention discloses a preparation method of a halogen-free flame-retardant dynamic vulcanized rubber waterproof coiled material. Two double-screw extruders are linked and parameters of the double-screw extruders are strictly controlled, so that the dynamic vulcanized rubber waterproof coiled material produced by the production process is high in shearing capacity, all the phases are uniformlymixed, and a uniform "sea-island structure" can be formed. The use amount of each component is reasonably formulated, so that the obtained product is better in physical and chemical properties, the product quality is stable, continuous production can be realized, product quality can be monitored in real time, and production efficiency of the production process is greatly improved. In addition, theprocess and the formula can be adjusted on line in real time for reducing the rejection rate.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular, the invention relates to a method for preparing a halogen-free flame-retardant 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...
