Abstract

The invention discloses a composite macromolecular waterproof board, which consists of high density polyethylene, linear low density polyethylene, a thermoplastic elastomer, an antioxidant, an anti-ageing agent and a filler. The composite macromolecular waterproof board has high permeability resistance, high barrier property, high penetration resistance, resistance to acid, alkali and various chemical substances, high elongation and wear resistance, is free from chemical pollution, and can effectively improve the surface energy of polyethylene. The invention also discloses a method for preparing the composite macromolecular waterproof board.

Description

technical field [0001] The invention relates to a composite polymer waterproof board, which belongs to the field of material chemistry. Background technique [0002] In places such as subways and tunnels, there are high requirements for the strength, elongation, puncture resistance, and construction methods of waterproof panels, and general waterproof membranes are difficult to meet their performance requirements. However, the traditional welding method to construct the waterproof board is troublesome to construct and the water channeling phenomenon occurs after the leakage point occurs, which brings inconvenience to the repair. At present, in order to facilitate construction, self-adhesive waterproof boards are usually used for construction. Traditional self-adhesive waterproofing materials such as self-adhesive bitumen membrane, EVA coated self-adhesive bitumen waterproofing sheet, ECB coated self-adhesive bitumen waterproofing sheet. Self-adhesive coils require the main...
