preparation example Construction

[0047] The present invention also provides a method for preparing a sound-insulating modified asphalt waterproof membrane, comprising the following steps:

[0048] a) Add tris hydrochloride and surfactant to water, after stirring evenly, adjust the pH value of the solution to 8.5 with sodium hydroxide, and add dopamine hydrochloride, add asphalt after stirring, and stir again After uniformity, stand for 24 hours to obtain modified asphalt;

[0049] b) Add the modified asphalt, EPDM rubber, silane coupling agent, asbestos wool, carbon fiber, vulcanizing agent, co-vulcanizing agent, antioxidant, and filler obtained in step a) to a high-speed mixing mixer, and heat the mixture at 50-70°C Stir for 60-100min to obtain the mixture;

[0050] c) Add the mixture obtained in step a) to the rubber mixer for plasticating and then kneading. The kneading temperature is controlled at 80-90°C, and the kneading time is 30-50 minutes. Rolled into a semi-finished waterproof membrane with a thi...

Abstract

The invention discloses a sound-proof modified asphalt waterproof roll and a preparation method thereof. The waterproof roll comprises the following components in parts by weight: 60-80 parts of modified asphalt, 20-30 parts of an ethylene-propylene-diene monomer, 2-3 parts of a silane coupling agent, 6-12 parts of asbestos wool, 1-2 parts of carbon fiber, 1-2 parts of a sulfurizing agent, 2-3 parts of a co-sulfurizing agent, 0.8-2 parts of an antioxidant and 20-30 parts of a filler, wherein the modified asphalt is polydopamine modified asphalt. The waterproof roll prepared by using the modified asphalt, the ethylene-propylene-diene monomer, the silane coupling agent, the asbestos wool, the carbon fiber, the co-sulfurizing agent, the antioxidant and the filler as raw materials is good in sound-proof performance, and has the advantages of high strength, large elongation at break and good waterproof performance.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a sound-insulating modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Since the 1970s, developed countries in the world have begun to change in the structure of waterproof materials, gradually developing to new waterproof materials such as modified asphalt, self-adhesive, and synthetic polymer materials. At present, foreign new waterproof materials have accounted for more than 90% of the total market, and product quality, function, and service life have reached a relatively high level. Since the waterproof engineering in our country began to use asphalt membranes in the 1970s, asphalt waterproof materials have always been the leading product of building waterproofing. At this stage, domestic bitumen waterproofing membrane technology is basically mature, but there are still defects such as poor sound insulation, l...
