Problems solved by technology

[0004] In order to effectively overcome the problem of cracking of the colored anti-skid pavement caused by the large shrinkage rate and insufficient elongation at break of the current water-based epoxy resin, as well as the problem of insufficient wear performance of the colored anti-skid pavement due to serious grain loss in the early stage, at the same time, the snow melting of the snow melting agent is integrated. Ice effect, further improving the service ability of colored pavement in ice and snow weather

Embodiment 1

[0051] 1. Preparation of component A of environmentally friendly colored non-slip pavement adhesive:

[0052] 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;

[0053] 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 relates to an environment-friendly colored antiskid pavement capable of melting ice and a preparation method of the environment-friendly colored antiskid pavement. The method comprises the following steps: firstly, repairing and sweeping the 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 antiskid pavement surface layer protective agent, and spreading potassium acetate particles within 3-5 minutes after spraying. 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. The potassium acetate particles can well sink into the transparent surface layer protective agent or are partially embedded on the surface of the surface layer protective agent, and can play a role in melting ice and snow in ice and snow weather.

Description

technical field [0001] The invention belongs to the technical field of road surface maintenance, and in particular relates to an ice-melting environment-friendly colored non-slip road surface and a preparation method thereof. Background technique [0002] China's highways are distributed in the north and south of the river, with different road conditions, usage environments and needs. In the winter season in northern China, ice and snow weather is often encountered, causing many traffics to be paralyzed or semi-paralyzed, seriously restricting and affecting the lives of residents, and also causing many hidden dangers to driving safety. [0003] Colored non-slip pavement can solve the problem of wet and slippery road surface caused by rainy and snowy weather to a certain extent. However, when the amount of snow is heavy, snow deposits in the gaps of the colored non-slip pavement and fills the structural depth of ceramic particles. The road surface has just lost the function ...
