Embodiment 1

[0027] Add 39 parts of warm water at 68°C into the beaker, and then add 1 part of the compound emulsifier of CSGS and OP-10 to the warm water, where CSGS and OP-10 (molar ratio) are 9:1, and stir to make 40 parts evenly. Parts of the emulsifier aqueous solution. The emulsifier solution is mixed with 60 parts of 140°C petroleum pitch, and then a colloid mill is added for rubber grinding to prepare an emulsified pitch. The CSGS is dodecyl dimethyl ammonium bromide which is a Gemini cationic surfactant, and the dodecyl dimethyl ammonium bromide is produced by the reaction of dodecyl dimethyl ammonium bromide in sulfuric acid solution Dodecane bromide, in which the molar ratio of dodecyl alcohol and sulfuric acid to hydrogen bromide is 1:2:0.1, dodecane bromide reacts with N,N'-dimethylbenzylamine to make dodecane The molar ratio of dodecyl dimethyl ammonium bromide, dodecyl bromide and N,N'-dimethylbenzylamine is 1:1. The dodecyl dimethyl ammonium bromide is in the Henan Dao Pure...

Embodiment 2

[0029] Add 39 parts of warm water at 68°C to the beaker, and then add 1 part of the compound emulsifier of CSGS and OP-10 to the warm water, where CSGS and OP-10 (molar ratio) are 7:3, and the mixture is evenly mixed to make 40 Parts of the emulsifier aqueous solution. The emulsifier solution is mixed with 60 parts of 140°C petroleum pitch, and then a colloid mill is added for rubber grinding to prepare an emulsified pitch. The CSGS is dodecyl dimethyl ammonium bromide, which is a Gemini cationic surfactant, which is purchased from Henan Daochun Chemical Co., Ltd.; in the compound emulsifier, OP-10 is nonylphenol polyoxyethylene Ether, purchased from Haian Petrochemical Co., Ltd.

Embodiment 3

[0031] Add 39 parts of warm water at 68°C to the beaker, and then add 1 part of the compound emulsifier of CSGS and octylphenol polyoxyethylene ether to the warm water, where the CSGS and octylphenol polyoxyethylene ether (molar ratio) is 5: 5. After stirring, make 40 parts of emulsifier aqueous solution evenly. The emulsifier solution is mixed with 60 parts of 140°C petroleum pitch, and then a colloid mill is added for rubber grinding to prepare an emulsified pitch. The CSGS is dodecyl dimethyl ammonium bromide, which is a Gemini cationic surfactant, purchased from Henan Daochun Chemical Co., Ltd.; in the compound emulsifier, OP-10 is nonylphenol polyoxyethylene Ether, purchased from Haian Petrochemical Co., Ltd.

Abstract

The invention discloses a nonionic OP-10 compound asphalt emulsifier and an application. According to an optimized compounding technology of the emulsifier, emulsified asphalt has good storage stability and traffic can be opened without addition of an accelerator and a retarder when CSGS and the OP-10 compound emulsifier account for 1% of the total amount of the emulsified asphalt and the mole ratio of CSGS to OP-10 is 7:3.

Description

Technical field [0001] The invention relates to the practical application of organic chemical products in the field of asphalt road pouring, belonging to the field of chemical engineering and building materials, and in particular to a non-ionic OP-10 compound asphalt emulsifier and its application Background technique [0002] Emulsified bitumen, also known as bituminous emulsion, generally refers to the oil-in-water emulsion with a certain storage stability formed by the bitumen dispersed in an aqueous solution containing emulsifiers, stabilizers, etc. in the state of particles. The preparation method of bitumen emulsion is generally to melt bitumen and disperse it in an aqueous solution containing emulsifier through emulsifying equipment. [0003] In the long-term practical engineering, people found that a single emulsifier often has poor emulsification effect and poor storage stability. The HLB value of asphalt emulsifier is required to be between 8-18. A single emulsifier has ...
