Interface agent and waterproof roll composite waterproof system and construction method thereof

Abstract

The invention relates to an interface agent and waterproof roll composite waterproof system and a construction method thereof, the interface agent and waterproof roll composite waterproof system comprises an interface agent layer brushed on a base surface and a waterproof roll layer attached to the interface agent layer after being dried; the waterproof coiled material layer is a thermoplastic polyolefin waterproof coiled material or a high-density polyethylene self-adhesive film waterproof coiled material; the interface agent coating is prepared from the following components in parts by mass: 20 to 30 parts of an ethylene-vinyl acetate water dispersion emulsion, 70 to 75 parts of water, 0.1 to 0.5 part of a defoaming agent, 0.1 to 0.2 part of a preservative, 0.2 to 0.5 part of a thickening agent, 0 to 0.1 part of a pH regulator, 0.5 to 1 part of cellulose and 1 to 5 parts of a water-based polyurea emulsion. According to the interface agent and waterproof roll composite waterproof system and the construction method thereof, the substrate and the waterproof roll are firmly bonded, and the waterproof effect is good.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a composite waterproofing system of an interface agent and a waterproofing membrane and a construction method thereof. Background technique [0002] During the construction process, the side walls often have concrete pouring defects such as poor vibration and honeycomb pockmarks, which lead to many difficulties in waterproofing construction and affect the waterproofing effect. [0003] For the planting roof, the waterproof membrane needs to have the function of root puncture resistance. Generally, two methods are used: one is "chemical root resistance", which prevents root puncture by adding a root resistance agent to the material, and the other is "physical root resistance". ", through the mechanical strength and hardness of the material itself to prevent the root system from piercing the coil. At present, there are very few root-blocking agents independently dev...

Problems solved by technology

[0005] For the construction of the bottom plate waterproof system, the conventional coil bottom plate is bonded with the cushion layer during construction, and not bonded with the structural layer, so it is impossible to truly "prevent water channeling"
