Abstract

The invention discloses furfural-free environment-friendly type high-seepage epoxy waterproof reinforcing paint as well as a preparation method and an application thereof. The paint comprises 40 to 75 parts of epoxy resin, 20 to 50 parts of ketone, 15 to 30 parts of furfural substitutes, 8 to 30 parts of active diluents, 1 to 5 parts of plasticizers, 2 to 8 parts of polyoxyethylene surfactants, 8 to 20 parts of polyamine, 2 to 9 parts of midbody active agents, 2 to 5 parts of silane coupling agents and 1 to 4.5 parts of promoting agents. The epoxy resin, the ketone, the furfural substitutes, the active diluents, the plasticizers and the polyoxyethylene surfactants are mixed to obtain solution A, the polyamine, the midbody active agents, the silane coupling agents and the promoting agents are mixed to obtain solution B, and the solution A and the solution B are mixed to obtain the paint. The paint has the advantages that the environment-friendly effect is realized, the toxicity is low, the operation danger is low, and the permeability and the mechanical strength are excellent. The paint is directly coated and brushed, the color is light after the curing, the attractive appearance of treatment objects is not influenced, and the paint can be used for the waterproof treatment and reinforcement of buildings.

Description

technical field [0001] The invention belongs to the field of waterproof reinforcement materials, and in particular relates to a furfural-free environment-friendly high-permeability epoxy waterproof reinforcement coating and its preparation method and application. Background technique [0002] At present, the main agent of most high-permeability epoxy resin series waterproof materials in the market is composed of epoxy resin, furfural, acetone, etc. Chinese invention patent 01107590.2 discloses a high-permeability carbonyl-epoxy waterproof reinforcing material, which has the characteristics of low viscosity, strong affinity and excellent mechanical properties. Among them, furfural, one of the main ingredients, is listed as a harmful substance. The semi-lethal dose for rats is 65mg / kg. Therefore, the pollution-free modification of high-permeability epoxy resin waterproof materials is very necessary. However, since furfural is an important active substance of this type of wat...
