Construction method for bonding polymer water-proof coiled material

Abstract

The invention discloses a construction method for splicing a macromolecular waterproof roll, which comprises the following steps: a. two double sticky tapes are adhered to both ends of a joint respectively to form a closed cohesive surface; b. the waterproof roll is fixed inside the joint, and an adhesive is coated on the cohesive surface; and c. the waterproof roll and the double sticky tapes are adhered to each other, and the cohesive surface is rolled by a pressure roller. The construction method improves the prior construction method, adopts the double sticky tape as the epoxy adhesive to form a closed receiving space, uses the pressure roller to grind a cohesive position of the waterproof roll and discharge air bubbles in the epoxy adhesive, makes the waterproof roll in a cohesive area practically combined with the epoxy adhesive which can not be overflowed from the cohesive position, realizes civilized construction, reduces the engineering cost, can perform visualized check on the construction quality through the transparent waterproof roll, and widen the application range.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a construction method for bonding polymer waterproofing coiled materials. Background technique [0002] The waterproof system composed of epoxy resin adhesives to lay polymer waterproof membranes can solve many construction problems and has a wide range of applications. However, during construction, there are many difficulties in operation, and some parts cannot be used. The promotion of this waterproof system and applications are limited. There are following disadvantages in the existing construction: [0003] 1. Epoxy resin adhesive is a viscous liquid and cannot be cured immediately. According to the existing construction requirements, it should be scraped on the front and rear sides of the bonding part of the polymer waterproof membrane. The epoxy resin adhesive cannot automatically maintain its shape. In the absence of overall restraint, the adhesive flows, ...

AI Technical Summary

Problems solved by technology

[0003] 1. Epoxy resin adhesive is a viscous liquid and cannot be cured immediately. According to the existing construction requirements, it should be scraped on the front and rear sides of the bonding part of the polymer waterproof membrane. The epoxy resin adhesive cannot automatically maintain its shape. Adhesive flow in the absence of global restraint, bond defects possible, and extremely difficult to apply on vertical surfaces and under ceilings

[0004] 2. Epoxy resin adhesive is applied on the bonding surface after being mixed on site. Bubbles will be generated when mixing and stirring. When glue is applied on both sides, the bubbles are difficult to get rid of, which will affect the bonding quality.

[0005] 3. After the epoxy resin adhesive is applied and scratched, it is buried immediately. It is difficult to control the thickness of the adhesive layer and the size of the bonding area. In order to prevent local adhesive defects, sometimes more adhesive is required, which increases the cost.

[0006] 4. Epoxy resin adhesive is irritating to the skin, and it is difficult to clean up no matter what it sticks to. Because the adhesive is exposed, it is easy to contaminate the environment, which is not conducive to civilized construction
