Embodiment 1

[0033] Taking the production of 500 grams of the product of the present invention as an example, the raw materials used and the proportioning thereof are:

[0034]

[0035] The preparation method of the low-cost high-performance road binder comprises the following steps: first heating the waste asphalt to a temperature of 135°C, and then adding catalytic oil slurry, dioctyl phthalate and coumarone resin together with the waste asphalt Mix and stir for 8 minutes, and keep the temperature of the mixture at 135°C, then pour it into the high-speed shearing equipment together with the waste rubber powder, and perform high-speed circulation shearing at 135°C for 15 minutes, so that the waste rubber powder and the mixture are completely mixed Melt to form a swollen structure of the mixture. Then, the mixture is heated to 150°C and ventilated and stirred for 250 minutes to further remove volatile components in the mixture and improve its high-temperature stability and aging resista...

Abstract

The invention discloses a low cost and high performance binding material for roads and a preparation method thereof. The binding material is composed of the following components by mass percentage: 50-80% of waste asphalt; 16-40% of catalytic slurry oil; 0.1-0.5% of dioctyl phthalate; 1-6% of coumarone resin; and 1-5% of waste rubber powder. The binding material provided by the invention takes waste asphalt as the main raw material, solves the problems of environmental pollution and recycling of a large amount of waste asphalt every year. Compared with the existing product technology, the product obtained by the invention can reduce environmental pollution and save resources. Catalytic slurry oil is added to fill light component absent in waste asphalt, so that the light component contentof waste asphalt can be increased to a reasonable level, and then all properties of waste asphalt can be restored. The invention also discloses a preparation method of the low cost and high performance binding material for roads.

Description

technical field [0001] The invention relates to the field of petroleum processing products, in particular to a low-cost, high-performance road binder and a preparation method thereof. Background technique [0002] Traditional asphalt roads use asphalt concrete as the surface material. Asphalt concrete is a mineral material (crushed stone or crushed gravel, stone chips or sand, mineral powder) composed of asphalt as the bonding material and a certain gradation under specific control conditions. etc.), the asphalt is used as a binder to bind the mineral materials together. With the rapid development of highway construction in our country, the construction mileage of asphalt roads continues to grow rapidly. In addition, the asphalt roads built in the past have gradually entered the overhaul period. The demand for asphalt binders is increasing every year. Therefore, the asphalt Prices are also rising, becoming more and more expensive, and the supply exceeds demand. At the same...
