Production device for pressure-sensitive adhesive for waterproof rolls

Abstract

The invention discloses a production device for a pressure-sensitive adhesive for waterproof rolls. The production device for the pressure-sensitive adhesive for the waterproof rolls comprises an extruder, a premixing forced feeder, a first quantitative material supply device, a second quantitative material supply device, a third quantitative material supply device, a fourth quantitative materialsupply device, a fifth quantitative material supply device and a sixth quantitative material supply device. According to the production device for the pressure-sensitive adhesive for the waterproof rolls, the pressure-sensitive adhesive is produced by a differential co-rotating twin-screw extruder, a mixing process is short in time, aging of materials can be prevented, the differential co-rotatingtwin-screw extruder can continuously produce the pressure-sensitive adhesive, the produced adhesive can be conveyed to a pre-paved roll production line in time, thus, the adhesive can be used up in time, and the adhesive does not need to be stored for a long time.

Description

technical field [0001] The invention relates to a production device of pressure-sensitive adhesive for waterproof coiled material. Background technique [0002] At present, there are two types of pre-paved waterproof membranes for underground space waterproofing: one is asphalt-based pre-paved waterproof membranes, and the other is non-bitumen-based pre-paved waterproof membranes. [0003] Non-asphalt-based pre-paved waterproofing membranes have developed rapidly in recent years. The main material of this type of waterproofing membranes is polymer sheets, and the adhesive layer is made of pressure-sensitive adhesives. During production and construction, there is no smoke and environmental protection. Good, convenient construction, comprehensive cost-effective. [0004] Conventional production of pressure-sensitive adhesives generally uses a ribbon reactor, but the mixing effect of the ribbon reactor is poor, and the production process takes a long time; and the ribbon react...

AI Technical Summary

Problems solved by technology

[0004] Conventional production of pressure-sensitive adhesives generally uses a ribbon reactor, but the mixing effect of the ribbon reactor is poor, and the production process takes a long time; and the ribbon reactor cannot be used for continuous production, and only intermittent production methods can be used. The batch size is one ton or more, and the product needs to be stored at 160-180°C for a period of time after it is discharged, so as to be used in the pre-laid coil production line; the glue needs to be kept at high temperature for a long time during the production and storage process, which is easy to cause glue aging , so that the performance of the glue is reduced, and the whole glue making process is not easy to control
