Abstract

The invention provides a hot-melt pressure-sensitive adhesive special for a high-weather-resistance non-asphalt-based pre-laid waterproof roll and a preparation method thereof. The hot-melt pressure-sensitive adhesive comprises the following raw material components: polyisobutene, naphthenic oil, an antioxidant, an anti-ultraviolet agent, an ultraviolet light absorber, a styrene-isoprene-styrene copolymer, a styrene-hydrogenated isoprene-diblock copolymer, C5 hydrogenated petroleum resin, highly hydrogenated C9 petroleum resin, hydrogenated monomer resin and high softening point hydrocarbon resin. The polyisobutylene is polyisobutylene having a viscosity of 100 cSt or more at 100 DEG C; the component of the anti-ultraviolet agent is salicylates. The prepared special hot-melt pressure-sensitive adhesive for the non-asphalt-based pre-laid waterproof coiled material has relatively good heat resistance, ultraviolet resistance and water resistance.

Description

technical field [0001] The invention relates to a special hot-melt pressure-sensitive adhesive for non-asphalt-based pre-paved waterproof coiled materials with high weather resistance and a preparation method thereof, belonging to the technical field of waterproof coiled materials. Background technique [0002] The hot-melt pressure-sensitive adhesive for non-bituminous-based waterproofing membranes used in the existing non-bituminous-based waterproofing membranes will have the following problems when used: the requirements for weather resistance of pre-laid waterproofing membranes are mainly heat resistance, These three aspects of UV and water resistance. The prior art hot-melt pressure-sensitive adhesives for non-bitumen-based waterproofing membranes are not strong in UV resistance, and the cohesion of the hot-melt pressure-sensitive adhesives for pre-applied waterproofing membranes is greatly reduced with the prolongation of the high-temperature curing time. The hot-melt...
