Embodiment 1

[0050] 1. Preparation of component A of environmentally friendly colored non-slip pavement adhesive:

[0051] 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;

[0052] 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 condensation recovery device at 5°C is installed at the outlet to collect the evaporated dimethyl carbonate. The reaction process needs to control the reaction temperature a...

Abstract

The invention discloses an anti-stripping 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 the environment-friendly colored antiskid pavement surface layer protective agent. 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. Compared with a conventional colored antiskid pavement and a water-borne epoxy resin colored antiskid pavement, the colored antiskid pavement disclosed by the invention is more excellent in environmental protection performance, crack resistance and durability.

Description

technical field [0001] The invention belongs to the technical field of pavement maintenance, and in particular relates to an anti-stripping environmentally friendly colored non-slip pavement and a preparation method thereof. Background technique [0002] Among the current colored anti-skid pavement, it is mainly divided into three categories: epoxy-based colored anti-skid pavement, polyurethane-based colored anti-skid pavement and MMA type colored anti-skid pavement. Epoxy-based colored non-slip pavement has high bonding strength and long service life, but it is prone to cracking due to high stress; polyurethane-based colored non-slip pavement has high elongation at break due to the low bonding strength of polyurethane, and its adhesion to the substrate is not as good as that of ring Oxygen resin, so it is prone to the problem of early ceramsite shedding and mid-late glossy board; compared with polyurethane-based colored non-slip pavement, the performance of MMA colored anti...
