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.

Abstract
The invention discloses an epoxy bitumen waterproof sheet material, comprising the following raw materials in parts by weight: 20-30 parts of n32 machine oil, 80-90 parts of bitumen, 0.3-0.6 part of alkyl glycoside, 0.4-1 part of ether ether ketone ketone, 0.1-0.2 part of tetrabutylammonium bromide, 3-5 parts of epoxy resin, 1-2 parts of 8-hydroxyquinoline, 3-4 parts of molybdenum boride, 28-30 parts of bentonite, 1-2 parts of monopotassium phosphate, 30-40 parts of 6% NAOH solution, 6-10 parts of alkali lignin and 2-3 parts of epoxy chloropropane; according to the epoxy bitumen waterproof sheet material, the alkali lignin is subjected to epoxidation processing, the crosslinking degree of lignin is increased, and after the processed alkali lignin is added into the resin system, the insulativity, mechanical property, heat stability, adhesiveness and anti-corrosion effect of the finished product can be effectively improved, the added 8-hydroxyquinolin can further improve the bonding strength and heat aging resistance.
Description
technical field [0001] The invention mainly relates to the field of coiled materials, in particular to an epoxidized 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.
