Abstract

The invention relates to the field of bitumen waterproof membranes, in particular to a preparation method of an SBS modified bitumen waterproof membrane. The preparation method comprises the following steps: preparing modified bitumen anti-aging self-adhesive glue in a ratio, coating two sides of a padding enhancing layer with the modified bitumen anti-aging self-adhesive glue, and covering the modified bitumen anti-aging self-adhesive glue layers with anti-sticking isolation films. The preparation method of the SBS modified bitumen waterproof membrane solves the problem that the conventional modified bitumen waterproof membrane is short in service life.

Description

technical field [0001] The invention relates to the field of asphalt waterproof coiled material, in particular to a preparation method of SBS modified asphalt waterproof coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. SBS modified asphalt waterproofing membrane is made of SBS rubber modified petroleum asphalt as the impregnated covering layer, made of polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. as the base, and plastic film as the anti-sticking isolation Layer, processed through material selection, batching, co-melting, impregnation, composite molding, curling and ...
