Energy-storage self-luminous epoxy resin mixture for road, preparation method and application

Abstract

The invention discloses an energy-storage self-luminous epoxy resin mixture for roads as well as a preparation method and application thereof. The energy-storage self-luminous epoxy resin mixture comprises the following components: coarse aggregate, fine aggregate, epoxy resin, a toughening agent, a curing agent and fluorescent powder, wherein the nominal particle size of the coarse aggregate is greater than 2.36 mm, the nominal particle size of the fine aggregate is 0.15-2.36 mm, and the nominal particle size of the fluorescent powder is less than 0.15 mm; wherein the epoxy resin accounts for6.0%-10.0% of the total mass of the coarse aggregate and the fine aggregate, the flexibilizer accounts for 0.4%-1.0% of the total mass of the coarse aggregate and the fine aggregate, the curing agentaccounts for 1.0%-2.5% of the total mass of the coarse aggregate and the fine aggregate, and the fluorescent powder accounts for 5.0%-10.0% of the total mass of the coarse aggregate and the fine aggregate. The advantages of the fluorescent powder are achieved by applying the colorless and transparent epoxy resin, so that the epoxy resin mixture is good in light transmission and ideal in luminouseffect, and the proportion of the epoxy resin can meet the requirement of pavement performance and has a protection effect on the fluorescent powder; the fluorescent powder with the nominal particle size smaller than 0.15 mm is adopted for replacing fine aggregate with the particle size smaller than 0.15 mm, so that the mechanical property of the pavement structure is not affected, and the beneficial effects of energy storage and light emitting are achieved.

Description

technical field [0001] The invention belongs to the field of road surface engineering, and in particular relates to a road-use energy-storage self-luminous epoxy resin mixture, a preparation method and an application. Background technique [0002] As of the end of 2018, the total mileage of rural roads in my country reached 4,039,700 kilometers. Rural roads are long and wide, and the installation of roadside lighting facilities is costly, time-consuming, consumes a lot of power resources, and causes strong light pollution. Therefore, rural roads in my country Lack of lighting facilities at night, ordinary signs and markings must be illuminated by lights to reflect light, resulting in pedestrians or non-motorized vehicles not being able to see the markings and markings in a timely and clear manner, resulting in danger, and at the same time bringing hidden dangers to traffic safety. Therefore, it is of great significance to develop energy-storing self-luminous pavements. [00...

Problems solved by technology

However, these two methods have certain limitations and deficiencies

Brushing the fluorescent coating on the pavement surface seriously destroys the structural depth of the pavement and reduces the skid resistance of the pavement, especially in rainy and snowy weather, which is very unfavorable to driving safety; in addition, the coating on the pavement surface is in direct contact with the tires, which is very It is easy to wear, which will cause the coating to peel off, resulting in unsatisfactory luminous effect, which makes the maintenance cost higher in the later period; and the coating is directly affected by climatic factors such as the sun, ice, snow, rain, etc., and is prone to aging, which gradually reduces the luminous performance

Incorporating fluorescent stone into the pavement mixture will reduce the strength and bearing capacity of the road surface; in addition, the luminous intensity of fluorescent stone is weak, and the luminous effect is not ideal
