Abstract

The invention discloses a novel non-asphalt-based self-adhesive waterproofing coiled material and a preparation method thereof. The coiled material comprises a main base, non-asphalt self-adhesive glue coating the main base and an isolating membrane. The non-asphalt self-adhesive glue comprises, by weight, 10-25% of a C5 / C9 copolymer resin, 3-4% of polyisobutylene, 10-25% of cycloalkyl rubber oil,3-12% of SIS rubber, 4-14% of styrene-butadiene rubber, 15-35% of a filler, 0.5-2.5% of a pigment and 4-6% of an auxiliary agent. Compared with the prior art, the novel non-asphalt-based self-adhesive waterproofing coiled material has high peeling strength, and the main base and the non-asphalt self-adhesive glue are not easily separated.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a novel non-asphalt-based self-adhesive waterproof coiled material and a preparation method thereof. Background technique [0002] The self-adhesive waterproof membrane does not need to be heated during construction, especially the self-adhesive membrane constructed by the wet laying method does not need to brush the base treatment agent on the base, which is safe in construction and friendly to the environment. It is a kind of waterproof that has developed rapidly in recent years Coil. The self-adhesive waterproofing membranes currently used in the market are mainly divided into asphalt-based self-adhesive waterproofing membranes and non-asphalt-based self-adhesive waterproofing membranes. Asphalt-based self-adhesive waterproofing membranes have poor adhesion under low temperature conditions; general non-asphalt-based waterproofing membranes have poor weather resistance and ...
