Abstract

The invention provides a non-asphaltic based self-adhered high polymer waterproof coiled material and a preparation method thereof. The non-asphaltic based self-adhered high polymer waterproof coiledmaterial is prepared from the following components: low-density polyethylene, high-density polyethylene, polyurethane, ethylene-vinyl acetate glyceride, barium sulfate, ultraviolet absorbent, antioxidant, silica gel, coupling agent, brucite powder, glycerin monostearate, cis-9-oleic alcohol and accelerant; the coupling agent is formed by mixing aluminic ester coupling agent DL-411, silane couplingagent KH-570 and titanate coupling agent 311 in mass ratio of 1: 2: 1. The non-asphaltic based self-adhered high polymer waterproof coiled material has good adhesion effect with the wooden basal plane, the heat-proof ageing performance and the anti-ultraviolet performance are strong.

Description

technical field [0001] The invention relates to a non-asphalt-based self-adhesive polymer waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof coiled materials. Background technique [0002] Traditional waterproofing membranes mainly use modified asphalt waterproofing membranes with hot-melt construction. Modified asphalt waterproofing membranes have good hydrophobicity, cohesion and ductility, can resist acid, alkali, and salt corrosion, and have good impact resistance. , are cheap and therefore widely used. However, the modified asphalt waterproof membrane is prone to aging and brittleness when heated, and it is inconsistent with the thermal expansion and contraction of the cement roof or metal roof, and it is easy to delaminate, which is affected by the waterproof effect. In addition, asphalt often contains naphthalene, anthracene, pyridine, phenol and other toxic substances, which have a strong odor during use, poll...
