Waterproof hard asphalt coiled material

Abstract

The invention discloses a waterproof hard asphalt coiled material. The coiled material comprises raw materials in parts by weight as follows: 6-10 parts of alkali lignin, 0.2-0.4 parts of oleic acid polyoxyethylene ester, 20-30 parts of hydroxyl silicone oil, 0.7-3 parts of aluminum ammonium sulfate, 5-7 parts of carbomer resin, 1-1.5 parts of chitosan, 3-5 parts of butyl methacrylate, 2-3 parts of aluminum dihydrogen phosphate, 20-26 parts of wollastonite powder, 10-20 parts of calcined gypsum powder, 0.7-1 part of sodium metaborate, 83-90 parts of asphalt, 30-40 parts of a 6% NaOH solution, 2-3 parts of epoxy chloropropane and 0.1-0.3 parts of stearamide. Epoxidation treatment is performed on the alkali lignin, the lignin molecule crosslinking degree is increased, the alkali lignin is added to a resin system, the insulation property, mechanical properties, the heat stability and the bonding effect of a finished product can be effectively improved, and the added gypsum powder has good hardness and good high-temperature-resistant and flame-retardant effects.

Description

technical field [0001] The invention mainly relates to the field of coiled materials, in particular to a hard 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 brittleness, high tempera...

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.
