Aromatic hydrocarbon oil asphalt waterproof roll and production process thereof

Abstract

The invention provides an aromatic hydrocarbon oil asphalt waterproof roll and a production process thereof. The aromatic hydrocarbon oil asphalt waterproof roll comprises a pre-paved and wetly-paved asphalt waterproof roll rubber material layer, wherein the pre-paved and wetly-paved asphalt waterproof roll rubber material layer is prepared from the following raw materials: 35%-42% of petroleum asphalt, 4%-10% of a softening agent, 4%-10% of aromatic hydrocarbon oil, 5%-15% of a modifying agent, 1%-10% of a tackifier, 2%-10% of an anti-ageing agent, 2%-6% of a plasticizer and 10%-20% of a filling agent. According to the aromatic hydrocarbon oil asphalt waterproof roll provided by the invention, the bonding performance of the aromatic hydrocarbon oil asphalt waterproof roll can be effectively improved and the bonding capability of overlapping joint in a construction process of the roll is extremely improved; the waterproof effect is improved; and after the waterproof roll is constructed and before a protection layer is formed, an overlapping joint edge of the material can be effectively prevented from falling under the action of day-night temperature difference.

Description

Technical field [0001] The invention belongs to the technical field of pre-laid and wet-laid asphalt waterproof coiled materials, and in particular relates to an aromatic oil asphalt waterproof coiled material and a production process thereof. Background technique [0002] Aromatic oil, also known as aromatic hydrocarbon or aromatic hydrocarbon, refers to a hydrocarbon containing a benzene ring structure in the molecule, a dark viscous liquid, and a viscosity (60°C) of 12-15°E. Flash point (open cup) 170~200℃. The aniline point is about 36°C. Aromatic hydrocarbon content 70% to 87%, saturated hydrocarbon content 20% to 35%, polar content content <25%, asphalt olefin content <0.5%. It is one of the basic products and basic raw materials of petrochemical industry, mainly including benzene, toluene and xylene, ethylbenzene, etc. [0003] Due to the current pre-laid and wet-laid asphalt waterproofing membrane rubber compound in the modification process, it is necessary to add ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems of insufficient stripping performance of pre-paved and wet-paved asphalt waterproofing membranes, low bonding effect between membranes and membranes, prone to lapping and falling off, and affecting the waterproofing effect of buildings, the present invention provides an aromatic hydrocarbon content Aromatic oil asphalt waterproofing membrane and its production process are relatively high, not volatile, good bonding performance between coiled material and coiled material, not easy to cause lapping and falling off, and have good waterproof effect of buildings
