Abstract

The invention discloses a bridge deck waterproof material which is prepared from the following components in parts by weight: 10-20 parts of polyurethane with vinyl ether as an end group, 60-70 parts of asphalt, 5-8 parts of 2, 4-diamino-6-diallylamino-1, 3, 5-triazine, 3-5 parts of p-toluenesulfonic acid, 15-25 parts of carboxyl-terminated SBS and 5-10 parts of a functional copolymer. The functional copolymer is a copolymer prepared from allyl pentafluorobenzene, vinyltriethoxysilane, 1-allyl-3-methyl imidazole chloride and allyl glycidyl ether through a copolymerization reaction. The invention further provides a preparation method of the bridge deck waterproof material. The bridge deck waterproof material is remarkable in waterproof effect, good in comprehensive performance, high in bonding strength, good in high-temperature resistance, ageing resistance and performance stability and long in service life.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a bridge deck waterproof material and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the progress of the society, the enthusiasm for modern city construction has been high. The construction of various municipal projects has enabled people to build beautiful homes and realize their dreams of modernization. The construction of roads and bridges is an important municipal engineering construction project. Its successful completion can stimulate economic development, improve transportation efficiency, and make people's travel more convenient and faster. "To get rich, build roads first" has become a consensus, and speeding up the construction of roads and bridges has become a conscious action of people. [0003] At present, in road construction, all kinds of bridges account for a considerable proportion...
