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

Abstract

The invention provides a reaction double-viscosity polymer waterproof coiled material and a production method thereof, which belong to the technical field of waterproof coiled materials. The waterproof membrane is coated with reactive sticky modified asphalt reactive viscose on the high-strength polyolefin thermoplastic elastomer tire base reinforcement layer by oiling counter-rollers, and then coated on the modified asphalt reactive viscose layer to prevent sticking made of isolation film. Modified asphalt reactive viscose is made of the following raw materials: 90# petroleum asphalt, SBR rubber, SIS thermoplastic rubber, epoxy resin powder, naphthenic rubber oil, active tackifying resin, plasticizer, antioxidant, crosslinking agent , cross-linking accelerator, inorganic filler; active tackifying resin is a mixture of tackifying resin tackifying resin JT-260, alkylphenol acetylene tackifying resin, and C5 petroleum resin. The present invention improves the initial tack and persistent tack by limiting the type and ratio of the rubber modifier and adding active tackifying resin in a targeted manner, so as to achieve a more excellent waterproof effect.

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...
