Embodiment 1

[0035] refer to figure 1 , an environment-friendly preparation method of modified waterproof asphalt, comprising the following steps:

[0036] S1: Prepare raw materials, 16 parts of base asphalt, 36 parts of vegetable asphalt, 24 parts of rock asphalt, 2 parts of anti-aging agent, 1 part of petroleum resin, 8 parts of rubber powder, 3 parts of modifier, 9 parts of accelerator, 6 parts of oxidant , 11 parts of deep eutectic solvent;

[0037] S2: Mixing, pour the matrix asphalt, vegetable asphalt and rock asphalt into the mixing tank for heating and stirring. The mass ratio of raw materials is: vegetable asphalt 40%, rock asphalt 36%, matrix asphalt 24%, vegetable asphalt contains Zibo, Vitamin E and a large amount of higher fatty acids, which are added to the base asphalt, can have the same viscosity reduction effect as the warm mix agent, which can fully coat the asphalt binder and the mineral material, which can not only improve the mechanical properties of the mixture, but ...

Embodiment 2

[0046] refer to figure 1 , an environment-friendly preparation method of modified waterproof asphalt, comprising the following steps:

[0047] S1: Prepare raw materials, 25 parts of base asphalt, 42 parts of vegetable asphalt, 36 parts of rock asphalt, 8 parts of anti-aging agent, 2 parts of petroleum resin, 12 parts of rubber powder, 4 parts of modifier, 18 parts of accelerator, 11 parts of oxidant , 13 parts of deep eutectic solvent;

[0048] S2: Mixing, pour the matrix asphalt, vegetable asphalt and rock asphalt into the mixing tank for heating and stirring. The mass ratio of raw materials is: vegetable asphalt 48%, rock asphalt 30%, matrix asphalt 22%, vegetable asphalt contains Zibo, Vitamin E and a large amount of higher fatty acids, which are added to the base asphalt, can have the same viscosity reduction effect as the warm mix agent, which can fully coat the asphalt binder and the mineral material, which can not only improve the mechanical properties of the mixture, ...

Abstract

The invention relates to the technical field of asphalt, and discloses a preparation method of environment-friendly modified waterproof asphalt, which comprises the following steps: S1, preparing the following raw materials in parts by weight: 15-30 parts of matrix asphalt, 35-45 parts of plant asphalt, 23-40 parts of rock asphalt, 0.5-10 parts of anti-aging agent and 0.5-3 parts of petroleum resin; s2, mixing: the matrix asphalt, the plant asphalt and the rock asphalt are poured into a stirring cylinder to be heated and stirred, and the mass ratio of the raw materials is as follows: 30-50% of the plant asphalt, 20-45% of the rock asphalt and 10-35% of the matrix asphalt; and S3, adding an additive. According to the present invention, the purposes of environmental protection and low pollution can be achieved through the cooperative use of the plant asphalt and the rock asphalt, the overall structure of the asphalt can be uniform and dense through the rubber powder so as not to easily crack in the actual application process, and the asphalt can have good high-temperature rut resistance and good water damage resistance through the modifier.

Description

[0001] The invention relates to the technical field of asphalt, in particular to a preparation method of an environment-friendly modified waterproof asphalt. Background technique [0002] Over the years, with the rapid development of my country's petroleum industry and the continuous increase in asphalt production, asphalt-based building waterproofing materials have gradually become the main raw materials for building waterproofing in my country. The commonly used construction asphalt varieties include general construction asphalt, roofing asphalt, waterproof and moisture-proof asphalt, waterproof engineering asphalt, etc., which are mainly used for roofing, ground waterproof and moisture-proof layer and other construction projects. [0003] Most of the current building waterproof materials in our country are based on asphalt. With the development of modern industry, not only the requirements for increasing the added value of asphalt, but also the protection of human health and ...
