Embodiment 1

[0031] 1. The preparation of the A component of the environment-friendly colored pavement surface protection agent:

[0032] 1) Extract castor oil (purity 99.5%), trimethylolpropane (TMP), dimethyl carbonate (DMC), HMDI, hydroxyethyl methacrylate and bismethylol butyric acid (DMBA) at 40°C Dry in a vacuum oven to remove moisture, then place in CaCl 2 Place in a desiccator at 25°C for 72 hours;

[0033] 2) Put 60 parts of HMDI in the reactor, adjust the reaction temperature to 70°C-75°C, and the stirring speed to 1500rpm, and pass N 2 Protection, N 2 A condensation recovery device at 5°C is installed at the outlet to collect the evaporated dimethyl carbonate (too high a reaction temperature will cause the molecular weight of the prepolymer to increase too fast, resulting in difficulty in subsequent graft modification. The reason for not adding a catalyst is to control the reaction rate ), then slowly drip the DMC solution that is dissolved with TMP and castor oil (containing...

Abstract

The invention discloses an environment-friendly colored anti-slip pavement surface layer protective agent and a preparation method thereof. The surface protection agent is composed of component A and component B with a mass ratio of 1.2-1.5:2. When in use, component A and component B are mixed evenly and sprayed on the road surface. The surface protection agent of the present invention adopts HMDI type isocyanate, which can prevent the yellowing and powdering caused by the ultraviolet aging of isocyanate with benzene ring structure, and at the same time, HMDI has lower reactivity than isocyanate with benzene ring structure, and has a longer operating time , but compared with HDI, the reactivity is higher, which avoids the problem of too long working time. Compared with the conventional colored anti-skid pavement, the colored anti-skid pavement with surface protective agent has significantly improved performance in water damage and fatigue tests.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, and in particular relates to an environment-friendly colored anti-slip road surface protective agent and a preparation method thereof. Background technique [0002] According to the different adhesives used in 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. At present, the main problems of most colored non-slip pavements include early cracking, early grain loss, insufficient water damage and fatigue resistance, and cannot be combined with multiple functions. Moreover, the colored anti-skid roads currently used in the market are seriously polluted and emit a lot of VOCs. However, in the past few decades, in the process of vigorously developing the transportation industry in my country, insufficient attention has been paid to the environmen...
