Problems solved by technology

[0004] The existing method to solve the aging and mild damage of asphalt pavement is to use asphalt to heat pouring, pouring, and paving on site. This method not only causes serious pollution and difficult construction, but also due to the rapid thickening and solidification of asphalt after cooling in the air. , can not penetrate into cracked fine cracks, can not play the role of seam repair and bonding
Ordinary emulsified asphalt spraying and flood irrigation are used for re

example 1

[0019] Example 1: Use modified emulsified asphalt containing 10%~60% modified epoxy resin (30%~70% solid asphalt), add 3%~10% hollow glass microspheres, and then add 5%~30% Water-based epoxy resin curing agent, fully mixed; then add mineral sand or quartz sand (particle size 3 mesh ~ 80 mesh), fully mixed and spread evenly on new and old asphalt concrete roads, bridges, and scrape. Part of the rubber penetrates into the cracks to play the role of filling, repairing and bonding; while the cured coating plays the role of heat insulation, heat preservation, anti-wear, increasing friction coefficient, protecting asphalt concrete, slowing down oxidation and aging . An appropriate amount of conductive carbon black and additives can also be added to eliminate static electricity and achieve dustproof effect.

example 3

[0021] Example 3: Use modified emulsified asphalt containing 10%~60% modified epoxy resin (30%~70% solid asphalt), add 10%~15% hollow glass beads, add 10%~15% Quartz powder (200 mesh ~ 2000 mesh), then add 5% ~ 30% water-based epoxy resin curing agent, fully mixed; spread on the flat roof of the building, also suitable for cement concrete and asphalt and other waterproof materials On the painted layer, remove a layer of gravel protection with a diameter of 3mm~10mm, which can play the role of waterproof, joint filling, heat insulation, heat preservation and weather resistance of cement concrete. This paint is also suitable for anti-rust, anti-aging, anti-corrosion, moisture-proof, thermal insulation of color steel tiles, glass steel tiles, and wood tiles. Compared with common materials, the cost is lower and the performance is better. It is also suitable for the waterproofing of underground buildings and the waterproofing and anticorrosion of building foundations.

Abstract

The invention relates to the technical field of engineering construction and maintenance, in particular to an epoxy resin emulsified asphalt mortar coating which can be widely applied to the fields of surface water prevention, crack pouring, leakage mending, bonding, thermal insulation, freeze prevention, heat insulation, noise reduction and the like of highways, bridges and buildings, and is prepared by the following procedures: using double-component emulsified asphalt (containing 30-70 percent of solid asphalt) containing 10-60 percent of modified epoxy resin as the bonding and film forming material of the coating, adding 3-15 percent of hollow glass beads, adding 5-30 percent of aqueous epoxy resin curing agent and blending the mixture uniformly, and then adding ore sand or high-strength quartz sand (with particle size of 3-80 meshes) accounting for 100-200 percent of the total amount of the mixture into the improved epoxy resin emulsified asphalt mortar coating. The epoxy resin emulsified asphalt mortar coating has the advantages that the viscosity is low and the permeability is good; the ductility and the flexibility as well as the fatigue resistant strength of a condensate are great; and a coating formed after curing does not dissolve or stick the tire; the compression resistance, the water leakage prevention capability and the wear resistance of the road surface are improved, the friction coefficient of the road surface is increased, and the capabilities of noise reduction, heat insulation and frost crack prevention of the road surface are enhanced.

Description

technical field [0001] The invention relates to the technical field of engineering construction and maintenance, in particular to an epoxy resin that can be widely used in the fields of highways, bridges, building surfaces, waterproofing, filling, leak repair, bonding, heat insulation, antifreeze and heat preservation, noise reduction, etc. Emulsified asphalt paint. Background technique [0002] The appearance and performance quality of highways, bridges, and buildings are the concrete manifestation and intuitive appearance of a country's national strength, advanced civilization, and degree of development. Roads, bridges, and roofs of buildings are the great wealth of the country and the people. Their service life and maintenance costs directly affect the operating costs of people's lives and work. my country's current roads, bridges, especially the total length of expressways rank among the top three in the world, mainly using asphalt pavement, and asphalt pavement is main...
