Abstract

The invention relates to a flame-resistant waterproof lignin-modified asphalt roll. The flame-resistant waterproof lignin-modified asphalt roll is of a five-layer structure which comprises, from top to bottom, a top isolating layer, an upper flame-resistant modified asphalt layer, a padding layer, a lower flame-resistant modified asphalt layer and a bottom isolating layer, wherein the The upper and lower flame-resistant modified asphalt layers are prepared from flame-resistant modified asphalt. The flame-resistant modified asphalt is prepared from the following raw materials by weight: 40 to 50 parts of phenolated lignin, 20 to 25 parts of a SBS modifier, 50 to 60 parts of petroleum asphalt No. 90, 5 to 10 parts of a silane coupling agent, 5 to 8 parts of modified nanometer calcium carbonate, 5 to 8 parts of polyoxyethylene polyoxypropylene ether, 6 to 9 parts of citric acid, 6 to 9 parts of fumed silica, 4.8 to 7.2 parts of a flame-resistant mixture and 3 to 5 parts of trihexyl o-acetylcitrate. The flame-resistant waterproof lignin-modified asphalt roll prepared in the invention is greatly improved in tearing strength, bonding performance, water resistance, ageing resistance, hightemperature resistance, saline-alkaline tolerance and the like.

Description

technical field [0001] The invention relates to a polymer waterproof coiled material, in particular to a flame-retardant lignin-modified asphalt waterproof coiled material and a production method thereof, belonging to the field of waterproof chemical materials. Background technique [0002] Petroleum asphalt has good adhesion, aging resistance and waterproof ability, and has been widely used as road construction, waterproof and sealing materials for a long time. It is one of the most widely used materials in waterproof and anti-seepage projects at home and abroad because of its advantages of easy availability of raw materials and low price when used in waterproofing projects. [0003] Conserving resources and protecting the environment are the basic national policies of our country. Lignin is the second largest natural organic compound after cellulose in nature. The pulp and paper industry worldwide produces about 50 million tons of industrial lignin per year. The dischar...
