Abstract

The invention discloses a light-cured single-component waterborne epoxide, a waterproof material and a preparation method of the waterproof material. The light-cured single-component waterborne epoxide is prepared from the following components in parts by mass: 40 to 60 parts of epoxy resin, 1 to 5 parts of acrylic acid, 0.2 to 0.6 part of polymerization inhibitor, 3 to 6 parts of diethylaminoethanol, 4 to 8 parts of ethylene glycol monobutyl ether, 2 to 4 parts of unsaturated anhydride, 1 to 2 parts of waterborne light initiator and 30 to 60 parts of water. The light-cured single-component waterborne epoxide adopts self-made modified emulsified asphalt of a light-cured waterborne epoxide system, is different from an existing double-component epoxy curing agent and a latent epoxy curing agent, has the advantages of being good in long-time room-temperature light-shielding storage stability and long in storage time; the room-temperature light-shielding storage can reach 6 months; the waterborne light initiator is added in the light-cured single-component waterborne epoxide; the curing-agent waterborne epoxide is enabled to be quick in curing speed under the action of natural light; the construction is convenient and the construction period is shortened.

Description

technical field [0001] The invention relates to a waterproof material for roads, in particular to a light-cured one-component water-based epoxy, waterproof material and a preparation method thereof. Background technique [0002] Emulsified asphalt is heat-melted asphalt, and through mechanical action, the asphalt is dispersed in the aqueous solution containing emulsifier in the form of fine droplets to form an oil-in-water asphalt emulsion. Emulsified asphalt can be used as penetrating oil, viscous oil, seal oil, slurry seal, etc., and can also be used for cold regeneration of old asphalt pavement materials, dust-proof treatment of gravel pavement and laying temporary pavement. At present, emulsified asphalt is a widely used building material, but it still has many shortcomings, such as too low softening point, poor heat resistance, and short service life. Although SBR and SBS modified emulsified asphalt has improved its performance, has the advantages of saving energy and ...
