Problems solved by technology

In the existing technology, the most widely used modified asphalt acid-resistant modifiers 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 generated 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

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 poly(butylene succinate), 1.2-2.6 parts of alkylether magnesium sulfonate, 2.3-3.5 parts of carbon fibre, 1.2-1.8 parts of stannic 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 salicytate. Compared with the existing modifier, the improved asphalt acid-resistant modifier has the following advantages of being applicable to all petroleum asphalts, low in mixing amount, easy to blend, free of dissociation, free of special equipment, good in dispersing performance, excellent in acid resistance, alkali resistance and waterproof performance, can play an excellent viscosity-reducing modification role after being added in the amount of 2-3% of asphalt, can significantly improve a softening point of the asphalt, can reduce the needle penetration, can resist a high-temperature wheel rut, and also can 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 existing technology, the most widely used modified asphalt acid-resistant modifiers 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 endange...
