Overlay material for delaying aging of colored asphalt and preparation method thereof

Abstract

The invention discloses an overlay material capable of delaying aging of colored asphalt and a preparation method of the overlay material, and specifically relates to the technical field of road engineering materials. The overlay material is composed of the following components (by weight): 1%-5% of a pressure-sensitive adhesive, 20%-35% of petroleum resin, 25%-40% of a light component, 0%-4.5% ofa toner, 0%-1.5% of a brightening agent and the balance of emulsified liquid soap. The overlay material disclosed by the invention can be directly sprayed on the surface of a colored asphalt pavement, can be conveniently and quickly constructed, can prevent colored asphalt from being in direct contact with air, and further delays color withering caused by oxidation of the colored asphalt and enhances color durability due to relatively strong adhesion of the overlay material.

Description

technical field

[0001] The invention belongs to the technical field of road engineering materials, in particular to an overlay material for delaying the aging of colored asphalt and a preparation method thereof. Background technique

[0002] With the introduction and implementation of national policies such as beautiful cities and beautiful villages, the construction of colorful colored roads is in full swing. Taking Shanghai as an example, in recent years, hundreds of kilometers of colored roads on both sides of the Huangpu River, Lingang area, and Chongming Island in Shanghai have been completed. or under construction. Among the many schemes of colored pavement, colored asphalt pavement occupies a dominant position in the construction of colored pavement due to its relatively stable performance and overall uniform appearance. However, as the components of colored asphalt volatilize and age, the color becomes dry and dark, and in severe cases, even stone peeling occurs. ...

Examples

Embodiment 1

[0019] A cover material for delaying the aging of colored asphalt, which contains 3wt% pressure-sensitive adhesive, 25wt% petroleum resin, 30wt% light components, 2.5wt% blue toner, 1wt% brightener and 38.5wt% emulsified soap .

[0020] The preparation method of the overlay material for delaying the aging of colored asphalt, as follows:

[0021] S1. After heating and melting the petroleum resin to a liquid state, add light components in a temperature-controlled 60°C, stir for 5 minutes until a cement is formed, and store the cement at a constant temperature of 160°C;

[0022] S2. Add the emulsified soap liquid treated at a constant temperature of 75°C to the colloid mill, and then add the cement prepared in step S1 to the colloid mill at 80°C for emulsification. After the emulsification is completed, add water-based acrylic resin, blue toner and The color brightening agent is stirred together for 30 minutes to obtain the covering material.

Embodiment 2

[0024] A cover material for delaying the aging of colored asphalt, which contains 1wt% of pressure-sensitive adhesive, 35wt% of petroleum resin, 25wt% of light components, 1.5wt% of brightener and 37.5wt% of emulsified soap.

[0025] The preparation method of the overlay material for delaying the aging of colored asphalt, as follows:

[0026] S1. After the petroleum resin is heated and melted to a liquid state, add the light component in a temperature control at 65°C, stir for 5 minutes until a cement is formed, and store the cement at a constant temperature of 160°C;

[0027] S2. Add the emulsified soap liquid treated at a constant temperature of 55°C to the colloid mill, and then add the cement prepared in step S1 to the colloid mill for emulsification at 60°C. After the emulsification is completed, add water-based acrylic resin and brightener, and Stir for 30 minutes to prepare the covering material.

Embodiment 3

[0029] A cover material for delaying the aging of colored asphalt, which contains 5wt% of pressure-sensitive adhesive, 20wt% of petroleum resin, 40wt% of light components, 4.5wt% of blue toner and 30.5wt% of emulsified soap.

[0030] The preparation method of the overlay material for delaying the aging of colored asphalt, as follows:

[0031] S1. After the petroleum resin is heated and melted to a liquid state, add the light component in a temperature control at 65°C, stir for 5 minutes until a cement is formed, and store the cement at a constant temperature of 160°C;

[0032] S2. Add the emulsified soap liquid treated at a constant temperature of 55°C to the colloid mill, then add the cement prepared in step S1 to the colloid mill at 80°C for emulsification, and add water-based acrylic resin and blue toner after the emulsification is completed. Stir together for 30 minutes to obtain the covering material.
