Abstract

The invention discloses a bridge deck waterproof material, which is characterized by comprising a liquid component and powder, wherein the liquid component is prepared from the following components inparts by weight: 10-15 parts of an acrylic polyurethane emulsion, 8-12 parts of asphalt modified waterproof emulsion, 3-5 parts of carboxyl-terminated liquid fluororubber, 2-4 parts of N-(3-acryloyloxy-2-hydroxypropyl)-3-aminopropyl triethoxysilane modified vegetable oil, 0.1-0.3 part of an initiator, 70-80 parts of water and 0.5-1.5 parts of an emulsifier; wherein the powder is prepared from thefollowing components in parts by weight: 80-90 parts of cement, 15-25 parts of silica sand, 3-5 parts of carborundum, 1-3 parts of nano boron fibers and 1-2 parts of a functional modified aluminum metal organic framework; wherein the mass ratio of the liquid component to the powder is 1: (3-5). The invention further provides a preparation method of the bridge deck waterproof material. The bridgedeck waterproof material provided by the invention is good in waterproofness, excellent in aging resistance and durability, strong in bonding property with a bridge deck, excellent in high-temperatureresistance 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] With the rapid development of my country's highways, especially expressways, the number of highway bridges is increasing day by day, and all kinds of bridges are springing up like mushrooms, which bring a lot of convenience to people's transportation and create another beautiful road for modern cities. landscape.
