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 high-reflective environment-friendly colored antiskid pavement and a preparation method thereof. The method comprises the following steps: firstly, repairing and sweeping 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 glass beads for pavement markings 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, and the elongation at break and the shear strength of the adhesive realize good matching, so the crack resistance and the fatigue resistance of the 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. The glass beads are scattered, so the retroreflection coefficient 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 high-reflection environment-friendly colored non-slip pavement and a preparation method thereof. Background technique [0002] With the development of road construction, road environmental protection, high efficiency, multi-functionality, customization, personalization and safety have become new development trends. In the current colored pavement, the ones that can be widely used in driving roads are mainly colored anti-skid pavement. This type of pavement has many functions such as anti-wear, anti-skid, traffic warning and beautification. However, with the gradual promotion of the application of colored anti-slip pavement, it is widely used in tourist attractions, park trails, long downhill, sharp turns, tunnel entrances and exits, airport runways, bus lanes, toll station entrances and exits, parking lots and other places, and Different types of plac...
