Abstract

The invention discloses a production process of a pressure-sensitive adhesive for a waterproof roll. The production process comprises the following steps: by taking a styrene-isoprene-styrene block copolymer, hydrogenated C5 petroleum resins, hydrogenated rosin resins, naphthenic oil, rutile titanium dioxide, an antioxidant and an ultraviolet light absorber as raw materials, producing the pressure-sensitive adhesive by adopting a differential co-rotating twin screw extruder. Time in the mixing process is short, material ageing can be avoided, and the differential co-rotating twin screw extruder is capable of realizing continuous production. The produced adhesive can be timely delivered to a pre-laying roll production line, so that the adhesive is used up in time; and therefore, the adhesive does not need to be stored for a long time. Moreover, the produced pressure-sensitive adhesive is bright in color, excellent in weather resistance, excellent in initial adhesion and holding power and high in peel strength with concrete.

Description

technical field

[0001] The invention relates to a production process 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 reac...
