Embodiment 1

[0030] One, the preparation method of adhesive A component of environment-friendly colored non-slip pavement:

[0031] 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;

[0032] 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 tempera...

Abstract

The invention discloses an environment-friendly adhesive for colored anti-skid pavements and a preparation method of the environment-friendly adhesive. The adhesive is composed of a component A and a component B. When the adhesive is used, 100 parts by mass of the component A, 150 parts by mass of the component B, 100 parts by mass of tap water and 10 parts by mass of pigment are mixed, stirred at the rotating speed of 1000-1500 rpm for 3-5 min and then poured on a construction road surface, and colored ceramic particles with the particle size of 1-3 mm are spread after the mixture is spread. The adhesive prepared by the invention is waterborne epoxy resin toughened and modified by polyurethane, the elongation at break can reach 8.3%, the tensile strength is kept at a relatively high value of 31.7 MPa, and the shear strength is remarkably improved compared with the commercially available waterborne epoxy resin and can reach 17.27 MPa. The crack resistance and the fatigue resistance of a colored anti-skid pavement prepared from the adhesive are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of road surface maintenance, and in particular relates to an adhesive for an environment-friendly colored anti-slip road surface and a preparation method thereof. Background technique [0002] At present, the research hotspots in the field of road construction and maintenance mainly focus on green, environmental protection, high performance, simple operation, convenient construction, and long service life. With the development of infrastructure, roads have developed from meeting the traffic requirements in the past to being functional, aesthetic and diversified. Colored pavement can play the role of traffic warning and beautify the environment, and realize the harmony and unity of function and performance, engineering and environment. [0003] 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...
