preparation example Construction
[0029] A preparation method of the above-mentioned additive, specifically comprising the following steps:
[0030] S1: prepare materials according to the above-mentioned components and the mass percentage of each component;
[0031] S2: Add the pigment body into the reaction kettle and stir evenly;
[0032] S3: After gradually adding polymer binder and brightener during the process of stirring the pigment body, continue stirring until the raw materials are evenly dispersed;
[0033] S4: Raise the temperature of the reactor, and gradually add ethylene-acetic acid polymer during the stirring process, and continue stirring;
[0034] S5: After the reaction kettle is cooled, it is granulated by a screw extruder to obtain a colored asphalt mixture additive.
[0035] Further, in the step S2, the stirring temperature is 85-115°C.
[0036] Further, in the step S3, the stirring time is 3-5 hours.
[0037] Further, in the step S4, the temperature of the reactor is increased to 130-14...

Abstract
The invention relates to an additive capable of enabling a colored asphalt mixture to be brighter. The additive comprises 78-84% by mass of a pigment body, 10-15% by mass of a polymer adhesive, 0.6-1.5% by mass of a brightening agent and 10-15% by mass of an ethylene-acetic acid polymer. The invention further discloses a preparation method of the additive. The preparation method specifically comprises the following steps: preparing materials according to the above components and the mass percentages of the components; adding the pigment body into a reaction kettle, and carrying out uniform stirring; gradually adding the polymer adhesive and the brightening agent in the process of stirring the pigment body, and continuing stirring until the raw materials are uniformly dispersed; raising thetemperature of the reaction kettle, gradually adding the ethylene-acetic acid polymer in the stirring process, and continuing stirring; and after the reaction kettle is cooled, conducting bracing andgranulating via a screw extruder to obtain the additive for the colored asphalt mixture. The additive of the invention has the beneficial effects that the additive can be effectively mixed with the asphalt mixture, the performance of color asphalt is effectively improved, fading is avoided, the service life of the color asphalt is prolonged, and cost is saved.
Description
technical field [0001] The invention relates to the technical field of road materials, in particular to an additive capable of making colored asphalt mixture brighter and a preparation method thereof. Background technique [0002] With the rapid development of my country's transportation infrastructure, people have put forward higher requirements for the coordination between asphalt pavement and the environment under the premise that road traffic meets the basic needs of daily travel. The traditional black asphalt pavement can no longer satisfy people in terms of color. demand, the new colored asphalt pavement has gradually been recognized by everyone because of its convenient traffic management guidance, prevention of traffic accidents, beautification of the city image, and reflection of the city's characteristics. It has been widely used in expressways, urban roads, tourist attractions and special-purpose Electronic toll lanes for emergency services and VIP pass holders. ...
