Problems solved by technology

[0006] In order to effectively overcome the problem of cracking of the colored anti-slip pavement caused by the large shrinkage rate and insufficient elongation at break of the current water-based epoxy resin, and the problem of insufficient wear performance of the colored anti-slip pavement caused by early grain loss, the luminous marking line is also integrated. The role of instruction and guidance

Embodiment 1

[0052] 1. Preparation of component A of environmentally friendly colored non-slip pavement adhesive:

[0053] 1) Dry castor oil (purity 99.5%), polyethylene glycol 2000, dimethyl carbonate, 4,4'-dicyclohexylmethane diisocyanate (referred to as HMDI) in a vacuum oven at 40°C to remove moisture , then placed in CaCl 2 Place in a desiccator at 25°C for 72 hours;

[0054] 2) Dissolve a mixture of 10 molar parts of castor oil and 10 molar parts of polyethylene glycol (molecular weight 2000) into 30 molar parts of dimethyl carbonate, and place it in a reactor at a temperature of 45°C , stir well until completely dissolved, then supply 99.99% N to the reactor 2 Protection, the reactor is heated by an oil bath, the reaction temperature is adjusted to 70°C, the mechanical stirring speed is 3000rpm, and the N 2 A 5°C condensation recovery device is installed at the outlet to collect the evaporated dimethyl carbonate. The reaction process needs to control the reaction temperature and ...

Abstract

The invention discloses a self-luminous environment-friendly colored antiskid pavement and a preparation method thereof. The method comprises: repairing and cleaning a pavement; then paving an environment-friendly colored antiskid pavement adhesive, and spreading colored ceramic particles on the adhesive; and after the adhesive is cured, spraying an environment-friendly colored anti-skid pavement surface layer protective agent, and spreading noctilucent stones or fluorescent powder within 3-5 minutes after the environment-friendly colored anti-skid pavement surface layer protective agent is sprayed. The environment-friendly colored antiskid pavement adhesive is toughened and modified by polyurethane, the elongation at break and the shear strength have better matching property, and the crack resistance and the fatigue resistance of a paved colored antiskid pavement are remarkably improved. By using the surface layer protective agent, the anti-stripping capability of the ceramic particles of the colored anti-skid pavement is effectively improved, and the water damage resistance of the environment-friendly colored anti-skid pavement is further improved. Due to the application of the fluorescent stone or the fluorescent powder, the night visual effect of the colored antiskid pavement is effectively improved, and higher safety indication is provided for the colored antiskid pavement in rainy days and at night.

Description

technical field [0001] The invention belongs to the technical field of pavement maintenance, and in particular relates to a self-illuminating environment-friendly colored non-slip pavement and a preparation method thereof. Background technique [0002] As the development of large-scale transportation construction gradually enters saturation, the construction of some low-grade highways has become the main focus of new transportation construction. Especially with tourist roads, mountain roads, country lanes and other places and areas lacking lighting facilities and incomplete safety protection facilities around, there are greater hidden dangers to the safety of pedestrians and vehicles. And these roads are often located in mountainous areas, shady places, etc., and the road safety hazards are relatively large. The application of colored non-slip pavement can effectively improve the driving safety of these road sections, but it still cannot solve the risks caused by poor visib...
