Embodiment 1

[0013] In the asphalt modifier (SAK) of the present invention, taking polypropylene is 25%, epoxy resin is 5%, polyethylene is 10%, stearic acid is 10%, ethylene bisstearamide is 50%, and above-mentioned raw material Put them into the mixing tank at room temperature in sequence, and after stirring for 10 to 15 minutes, the rotation speed is 80 to 110 rpm, which is the finished product of asphalt modifier.

[0014] When in use, add CNPC Xingneng AH-70 or base asphalt Maoming 90# + 3% (SAK) asphalt modifier to the base asphalt, and then stir at a temperature of 150°C for 30 to 60 minutes to prepare Into uniformly mixed, high-quality modified asphalt. Then, mix the above-mentioned modified asphalt with the set ingredients (granite is used for coarse orthopedics, limestone is used for fine orthopedics, and machine-made sand is used for sand).

[0015] Or first mix the asphalt modifier of the present invention and the set ingredients evenly at a temperature higher than 150°C, then...

Embodiment 2

[0017] In the asphalt modifier (SAK) of the present invention, taking polypropylene is 20%, epoxy resin is 7%, polyethylene is 10%, stearic acid is 8%, ethylene bisstearamide is 55%, and above-mentioned raw material Put them into the mixing tank at room temperature in order, and after stirring for 10 to 15 minutes, the asphalt modifier is finished.

[0018] Add the above-mentioned finished asphalt modifier to the base asphalt Zhongyou Xingneng AH-70 or base asphalt Maoming 90#, and then stir at a temperature of 150°C for 30 to 60 minutes to make a well-mixed, high-quality modified asphalt. Then, mix the above-mentioned modified asphalt with the set ingredients (granite is used for coarse orthopedics, limestone is used for fine orthopedics, and machine-made sand is used for sand).

Embodiment 3

[0020] In the asphalt modifier (SAK) of the present invention, getting polypropylene is 28%, epoxy resin is 9%, polyethylene is 9%, stearic acid is 9%, ethylene bis-stearamide is 45%, and above-mentioned raw material Put them into the mixing tank at room temperature in order, and after stirring for 10 to 15 minutes, the asphalt modifier is finished.

[0021] Add the above-mentioned finished asphalt modifier to the base asphalt Zhongyou Xingneng AH-70 or base asphalt Maoming 90#, and then stir at a temperature of 150°C for 30 to 60 minutes to make a well-mixed, high-quality modified asphalt. Then, mix the above-mentioned modified asphalt with the set ingredients (granite is used for coarse orthopedics, limestone is used for fine orthopedics, and machine-made sand is used for sand).

Abstract

The invention discloses a modifier of pitch for road and water-proofing material, which comprises the following steps: allocating with mass percent as 20-30% polypropylene, 3-10% epoxide resin, 8-10% polyethylene, 8-10% geoceric acid and 40-60% ethylene distearamide; mixing; stirring for 10-15 min; getting the product. This product possesses good stability and predominant water resistance, which can be fit for all of asphalt.

Description

technical field [0001] The invention relates to an asphalt modifier, in particular for roads and waterproofing materials. Background technique [0002] At present, the asphalt pavement mainly has problems such as pavement softening and oil flooding in summer, severe rutting with waves and bumps, and cracking at low temperature in winter. In order to improve the quality of asphalt pavement, with the development of highway traffic, the concept of asphalt modifier has been accepted by people, and modified asphalt has been more and more widely used. In the existing technology, the most used asphalt modifiers in China are SBS and PE, but both of them are not easy to be compatible with asphalt when used, require special shearing equipment and high energy consumption, and are easy to construct. Poor performance, a lot of waste smoke and gas are produced during construction, causing environmental pollution and endangering the health of operators. At the same time, the cooling speed...
