Reactive multiplied adhesive macromolecule waterproof roll and production method thereof

Abstract

The invention provides a reactive multiplied adhesive macromolecule waterproof roll and a production method thereof and belongs to the technical field of waterproof rolls. The waterproof roll is prepared by smearing a reactive adhesive type modified asphalt reactive adhesive to a high-toughness polyolefin thermoplastic elastomer substrate reinforcing layer by using coating pair rollers, and by pasting an anti-sticking isolation membrane to the modified asphalt reactive adhesive. The modified asphalt reactive adhesive is prepared from the following raw materials: #90 petroleum asphalt, SBR (styrene butadiene rubber), SIS (styrene-isoprene-styrene) thermoplastic rubber, epoxy resin powder, naphthenic base rubber oil, an active tackifying resin, a plasticizer, an antioxidant, a cross-linkingagent, a cross-linking promoter and an inorganic filler; and the active tackifying resin is a mixture of a tackifying resin JT-260, an alkylphenol acetylene tackifying resin and a C5 petroleum resin.By defining types and ratios of rubber modifiers, and specifically adding the active tackifying resin, the primary viscosity and the lasting viscosity of the waterproof roll can be improved, and thusan excellent waterproof effect can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of waterproof coiled material, in particular to a reaction double-adhesive polymer waterproof coiled material and a production method thereof. 【Background technique】 [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, subways, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. There is no leakage connection between the engineering foundation and the building. It is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to its main waterproofing materials, it can be divided into asphalt waterproofing materials, polymer modified There are three types of permanent waterproof membranes and synthetic polymer waterproof membranes. The traditional asphalt waterproof membrane is a rollable sheet waterproof material made by dippi...

AI Technical Summary

Problems solved by technology

However, the current reaction-bonded wet-laid polymer waterproofing membrane has the following defects in use: the reaction-bonding waterproofing membrane is removed under normal construction conditions to expose the reactive adhesive material, and then adhere to the base layer. to form a waterproof layer

However, when the base layer is uneven, there is floating dust on the surface, the base layer is wet or the temperature is low, the reaction adhesive waterproof membrane will not be firmly bonded to the base layer, and it is easy to form a hollowing phenomenon, which is equivalent to the fact that the membrane is lifted from the base layer after construction. The interface after peeling off is detached, and the modified asphalt material cannot be left on the construction base, which will affect the waterproof effect
