Problems solved by technology

[0004] Traditional waterproof membranes are difficult to use underwater; even some specially treated membranes that can be used underwater have limited underwater adhesive performance, and are easily damaged or peeled off by external forces after bonding; moreover, underwater adhesive It cannot be completed in a short period of time, the construction is difficult and the efficiency is low
[0005] The existing technology has the following defects: (1) The underwater bonding time is too long; (2) The peeling strength of the underwater bonding is low; (3) The resistance to chloride ion penetration is poor; (4) The peeling strength is small

Abstract

The invention provides an underwater strong and fast bonding waterproof coiled material. The waterproof coiled material is a three-layer composite structure, including an upper surface layer, a middle layer and a lower surface layer. The upper surface layer is a strong cross film, the middle layer is a rubber layer, and the lower surface layer is an isolation film. The middle layer is composed of the following components: terpene resin, C5 hydrogenated resin, isobutylene, coumarone resin, asphalt, aromatic oil, SBS, SIS, SBR, rubber powder, mineral powder. The underwater bonding time of the waterproof coiled material of the present invention is 8-15s; the underwater bonding and peeling strength is 1.2-1.5 N / mm; the chloride ion permeability resistance is 4.4×10-3-4.7×10-3 mg / c .m2.d.

Description

technical field [0001] The invention in this paper relates to a special waterproof coiled material, in particular to an underwater strong quick-bonding waterproof coiled material and a preparation method thereof, belonging to the field of waterproof materials. Background technique [0002] In a humid or humid environment, due to the wetting or penetration of water on the surface of the roll of wet-laid waterproof roll material, the water covering the surface of the lap joint edge rubber material will attenuate or disappear the viscosity of the roll material, making it The bonding with the overlapping edge is not strong, there are gaps, hollows, and no strength. Water seepage, water leakage and other phenomena often occur, which affect the normal use of the building and constitute a safety hazard. [0003] The corrosion of marine reinforced concrete structures is mainly caused by chloride ion corrosion. The higher the concentration of chloride ions in the steel structure, th...
