Abstract

The invention provides a hot-melt pressure-sensitive adhesive as well as a preparation method thereof and a waterproof coiled material and belongs to the technical field of waterproof coiled materials. The hot-melt pressure-sensitive adhesive can be used for solving the problem that the existing hot-melt pressure-sensitive adhesive cannot simultaneously have low-temperature bending property, good holding power and excellent temperature resistance. The hot-melt pressure-sensitive adhesive is prepared from raw materials comprising a first elastomer, first polyisobutylene, and a first C5 petroleum resin, wherein the first elastomer is polystyrene-polyisoprene-polystyrene ethylene elastomer; and the first polyisobutylene is polyisobutylene having molecular weight less than 1000 and a pour point of -30 DEG C to -4 DEG C; and first C5 petroleum resin is solid alicyclic hydrocarbon hydrogenated petroleum resin having a softening point of 100 DEG C-127 DEG C. The hot-melt pressure-sensitive adhesive provided by the invention can be applied by coating at 120 DEG C-140 DEG C and has the advantages of excellent low-temperature bending property and good adhesive force to various materials under normal-temperature conditions, holding power and excellent anti-aging property.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a hot-melt pressure-sensitive adhesive, a preparation method thereof, and a waterproof coiled material. Background technique [0002] GB / T 23457 "Pre-laid / wet-laid waterproof membrane" clearly stipulates that the low-temperature bendability requirement for P-type products is -25°C without cracks. Generally speaking, high-density polyethylene pre-laid anti-adhesive waterproofing membrane products include three-layer functional structure, namely carrier polymer sheet, main polymer hot-melt pressure-sensitive adhesive film layer, and functional elastic coating. Among them, the thickness of the elastic coating is only a few microns, and it is a discontinuous film layer from a microscopic point of view. It is mainly used to prevent the product from sticking to itself and resist ultraviolet rays. Therefore, it is generally not necessary to examine the el...
