Problems solved by technology

Ordinary emulsified asphalt spraying and flood irrigation are used for repairing, although the construction is convenient and the flood irrigation effect is good, but due to the low melting point of emulsified asphalt, its adhesion rate will drop sharply with the increase of t

Embodiment Construction

[0014] The present invention adds 5% to 10% of liquid rubber emulsion (such as block copolymer of styrene butadiene styrene or styrene-acrylic rubber emulsion referred to as SBS) in emulsified asphalt (containing 30% to 70% of solid asphalt). ) polymer modified material to increase the adhesion; add 10%~20% modifier; add 3%~20% hollow glass microspheres, mix well; finally add the total amount of the above mixture 100%~200 % of ore sand and quartz sand with different particle sizes (particle size is 3 mesh to 200 mesh). The modifier is natural asphalt with high softening point or polymer modified asphalt.

[0015] The preferred embodiments of the present invention are further described below. In the production formula of emulsified asphalt, polymer modified materials such as liquid rubber emulsion are added to increase adhesion, and natural asphalt or high molecular polymer modified materials with high softening point can also be added. Modifiers such as non-toxic asphalt can ...

Abstract

The invention relates to the technical field of engineering construction and maintenance, and especially relates to a modified emulsified asphalt paint which is widely applicable to the fields of water proofing, crack pouring, leakage mending, bonding, heat isolation, antifreezing and thermal insulation of surfaces of highway, bridges, and buildings; 5%-10% of polymer-modified materials of liquidrubber emulsion are added into the emulsified asphalt (containing 30%-70% of solid asphalt) to increase bonding force; 10%-20% of modifiers are added; 3%-20% of hollow glass beads are added, and the mixture is mixed uniformly; finally ore sand and quartz sand with different particle sizes and with an amount of 100%-200% of the total amount of the mixture are added. The paint can prolong the service life of asphalt pavement, and increase the friction coefficient of the pavement and the compressive resistance and impact resistance of the coating; the hollow honeycomb structure can not only achieve the effect of noise reduction, but also perform thermal insulation for the pavement so as to prevent the asphalt concrete layer from being damaged by high-temperature softening of the pavement in summer and from generating ruts, or reduce the damage and ruts of the asphalt concrete layer; and the paint can also prevent the damage due to low-temperature embrittlement in ice and snow in winter.

Description

technical field [0001] The invention relates to the technical field of engineering construction and maintenance, in particular to a modified emulsified asphalt coating that can be widely used in the fields of highways, bridges, building surfaces, waterproofing, joint filling, bonding, heat insulation, antifreeze and heat preservation, and noise reduction. . 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 highways, bridges, and especially highways rank among the top three in the world in terms of total length, and asphalt is mainly used for pavement. Therefore, the mai...
