Improved antioxidant asphalt waterproof coiled material

Abstract

The invention discloses an improved antioxidant asphalt waterproof coiled material, which comprises the following raw materials with parts by weight: asphalt 82-90, thiodipropionic acid 0.3-0.4, water-soluble lanolin 2-3, brominated polystyrene 6-8, methyl tin mercaptide 0.1-0.2, antioxygen 1010 0.8-2, scolecite 4-6, light calcium carbonate 20-26, dibutyl maleate 2-3, alkylated diphenylamine 0.1-0.2, 6% sodium hydroxide (NaOH) solution 30-40, alkali lignin 6-10, epichlorohydrin 2-3 and machine oil 21-30. The improved antioxidant asphalt waterproof coiled material epoxidizes the alkali lignin, improves degree of crosslinking of lignin molecules, can effectively improve insulativity, mechanical property, heat stability, adhesiveness and preservative effect by being added into a resin system, and can play the excellent role of high-temperature oxidation resistance by adding the alkylated diphenylamine into the machine oil.

Description

technical field [0001] The invention mainly relates to the field of coiled materials, in particular to an improved anti-oxidation asphalt waterproof coiled material. Background technique [0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls, called waterproof rolls, which are bendable sheet-like waterproof materials. Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building, it is the first barrier for the waterproofing of the whole project, and it plays a vital role in the whole project, and asphalt is recognized as a material with good waterproof performance, but due to the low temperature of the original asphalt The characteristics of britt...

Problems solved by technology

Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building, it is the first barrier for the waterproofing of the whole project, and it plays a vital role in the whole project, and asphalt is recognized as a material with good waterproof performance, but due to the low temperature of the original asphalt The characteristics of brittleness, high temperature flow resistance and poor aging performance need to be improved through technology

At present, the technical improvements for waterproofing mainly include catalytic oxidation asphalt, polymer modified asphalt, etc. These methods have high modification costs, complex processes, and have poor waterproof effects over time, and some are not conducive to construction.
