An Improved Asphalt Acid Resistance Modifier

Abstract

The invention discloses an improved asphalt acid-resistant modifier, which is prepared from the following raw materials in parts by weight: 2.5-5 parts of polybutylene succinate, 1.2-2.6 parts of magnesium alkyl ether sulfonate, and 2.3 parts of carbon fiber -3.5 parts, 1.2-1.8 parts of tin oxide, 3.6-4.7 parts of ferricyanate, 1.3-2.6 parts of polyacrylamide-glyoxal resin, 0.8-2.5 parts of dibromomethane and 2.3-3.5 parts of phenyl salicylate. Compared with the existing modifiers, the present invention has the following advantages: it is suitable for all kinds of petroleum asphalt, and the mixing amount is low, and the addition of 2% to 3% of the amount of asphalt can achieve an excellent viscosity-reducing modification effect; easy to mix , no segregation, no need for special equipment, good dispersibility, acid resistance, alkali resistance, waterproof performance is very superior; can significantly increase the softening point of asphalt, reduce the penetration, can not only resist high temperature rutting, but also prevent low temperature cracking.

Description

technical field [0001] The invention relates to an improved asphalt acid-resistant modifier, which belongs to the field of building materials. Background technique [0002] At present, the asphalt pavement mainly has problems such as road softening and oil flooding in summer, severe rutting and waves, 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 improved asphalt acid-resistant modifier has been accepted by people, and modified asphalt has been more and more widely used. In the prior art, the most improved acid-resistant asphalt modifiers used in China are SBS and PE, but both of them are not easy to be compatible with asphalt when used, requiring special shearing equipment and high energy consumption, and The construction workability is poor, and a lot of waste smoke and gas are generated during construction, causing environmental pollution and endangering the health o...

Problems solved by technology

In the prior art, the most improved acid-resistant asphalt modifiers used in China are SBS and PE, but both of them are not easy to be compatible with asphalt when used, requiring special shearing equipment and high energy consumption, and The workability of construction is poor, and 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 is slow, prolonging the opening time, which is extremely unfavorable to traffic construction
