[0010] The invention is an improved asphalt modifier, which is made of the following raw materials in parts by weight:

[0011] 2.5 parts of nano silicon oxide, 3.2 parts of magnesium dialkyl sulfosuccinate, 1.7 parts of magnesium silicate, 3.3 parts of polyurethane, 1.2 parts of sodium lactate, 0.7 parts of soybean protein isolate, 0.6 parts of phenylethylphenol polyoxypropylene polyoxyethylene ether Parts and 1.2 parts of sodium butyl naphthalene sulfonate.

Embodiment 2

[0013] The invention is an improved asphalt modifier, which is made of the following raw materials in parts by weight:

[0014] 1.2 parts of nano silicon oxide, 2.5 parts of magnesium dialkyl sulfosuccinate, 1.5 parts of magnesium silicate, 2.5 parts of polyurethane, 0.5 parts of sodium lactate, 0.5 parts of soybean protein isolate, 0.5 parts of phenylethylphenol polyoxypropylene polyoxyethylene ether parts and 0.5 parts of sodium butyl naphthalene sulfonate.

Embodiment 3

[0016] The invention is an improved asphalt modifier, which is made of the following raw materials in parts by weight:

[0017] 3.5 parts of nano silicon oxide, 3.7 parts of magnesium dialkyl sulfosuccinate, 2.3 parts of magnesium silicate, 4 parts of polyurethane, 1.6 parts of sodium lactate, 1.8 parts of soybean protein isolate, 0.8 parts of phenylethylphenol polyoxypropylene polyoxyethylene ether Parts and 1.7 parts of sodium butyl naphthalene sulfonate.

[0018] Compared with the existing modifiers, the present invention adds magnesium succinic acid dialkyl sulfonate, magnesium silicate and soybean protein isolate in the production process of asphalt mixture, and forms a lubricating polymer chain inside the cement after adding. structure, greatly reducing the mixing and rolling temperature of the mixture, saving energy consumption; good compaction performance, reducing the number of rolling times; good road surface quality, good high temperature anti-rutting ability, water...

Abstract

The invention discloses an improved asphalt modifier, which is made by the following raw materials in parts by weight: 1.2-3.5 parts of nanometer silicon oxide, 2.5-3.7 parts of magnesium succinic acid dialkyl acid sulfonate, 1.5-2.3 parts of magnesium silicate, 2.5-4 parts of polyurethane, 0.5-1.6 parts of sodium lactate, 0.5-1.8 parts of soybean protein isolate, 0.5-0.8 parts of phenethyl phenol polypropylene-polyoxyethylene ether, and 0.5-1.7 parts of sodium butyl naphthalene. The magnesium succinic acid dialkyl acid sulfonate, the magnesium silicate and the soybean protein isolate are added into the production process of an asphalt mixture, and a lubricant high-polymer chain structure is formed in the bonding agent, the mixing and grinding temperatures of the mixture are greatly reduced, the energy consumption is reduced, the compactness performance is good, the grinding times are reduced, the road surface quality is good, and the high-temperature anti-rutting performance, the resistance to moisture damage, and the ageing resistance are good.

Description

technical field [0001] The invention relates to an improved asphalt modifier and belongs to the field of building materials. Background technique [0002] In modern society, due to the sharp increase in traffic flow and driving frequency, the axle load of freight vehicles continues to increase, and one-way driving in separate lanes is generally implemented. The ability to resist cracking at low temperature; improve wear resistance and prolong service life. The existing petroleum asphalt is no longer suitable for changes in the road surface environment, so people have developed modified road asphalt. This modified asphalt has better performance, but the price is relatively high, and it is not suitable for large-scale popularization and application. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an improved asphalt modifier with low raw material cost, good road surfac...
