Abstract

The invention provides a pre-laying self-adhesion polymer modified bituminous waterproof sheet material. The waterproof sheet material comprises a modified bitumen layer, and the modified bitumen layer is prepared from, by weight, 75-80 parts of bitumen 130, 50-55 parts of bitumen 90, 8-9 parts of wax oil, 7-8 parts of propyl p-hydroxybenzoate, 11-14 parts of coumarone resin, 9-12 parts of SBR, 5-5.8 parts of EVA, 7-9 parts of coal tar, 7-8 parts of xanthan gum, 12-15 parts of dicyclopentadiene petroleum resin, 15-17 parts of polyterpene phenolic resin, 2-2.5 parts of sorbitol, 4-5 parts of ananti-oxidant and 4-5 parts of a thickening agent. The bituminous waterproof sheet material is used for underground waterproof engineering in a cold region, the pre-laying self-adhesion effect is goodin a low-temperature environment, after the bituminous waterproof sheet material and post-cast concrete are immersed into water, the peeling strength is high, the static load capacity is high, and the water channeling resistance is high.

Description

technical field [0001] The invention relates to a pre-paved self-adhesive polymer modified asphalt waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof coiled materials. Background technique [0002] The pre-laying of waterproof membrane refers to the waterproof membrane that the structural concrete is directly poured on the waterproof membrane, and the self-adhesive layer of the membrane and the concrete have good adhesion to achieve the anti-adhesive effect of pre-laying. It includes two categories: polymer-based membranes with a self-adhesive layer on the surface and polyester tire self-adhesive membranes with modified asphalt as the main body. [0003] Pre-paved self-adhesive polymer modified bitumen waterproofing membrane itself has the function of self-adhesive, easy to construct, and easy to form a fully enclosed integral waterproof layer; in terms of material properties, its tensile force and heat resistance are ...
