Problems solved by technology

[0007] One of the purposes of the patent of the present invention is to solve the problem of using solvents for liquid quick-cracking asphalt emulsifiers at normal temperature and the problem of increasing the packaging and transportation costs of products due to the low content of emulsifiers due to the presence of solvents, and at the same time solve the problems of emulsifiers A large number of solvents existing in the medium increase the technical problems such as environmental pollution, and provide a double Y type liquid fast-cracking cationic emulsifier for SBS modified asphalt emulsification, the double Y-type liquid fast-cracking cationic emulsifier for SBS modified asphalt Because the agent is liquid at room temperature, it is convenient to use, and it does not need to be heated to melt into liquid when used. At the same time, because it is solvent-free, all double Y-type liquid fast-cracking cationic emulsifier raw materials used for SBS modified asphalt emulsification participate in emulsification, so its When used for the emulsification of SBS modified asphalt, its usage is relatively reduced, thereby reducing the cost of raw materials for the preparation of emulsified asphalt

Abstract

The invention discloses a double-Y-type liquid fast-splitting cationic emulsifier used for emulsification of SBS modified asphalt and its application. 1 The molecular formula is CnHm, wherein n is a natural number of 12-18, m is 2n+1, 2n-1, 2n-3 or 2n-5; it is liquid at room temperature and can be directly used for SBS modified asphalt emulsification, and its consumption is relatively Reduced, the use process is environmentally friendly, no pollution to the environment, the obtained emulsified asphalt has good stability, longer storage time, good adhesion between emulsified asphalt and aggregates, and better waterproof performance and anti-stripping performance. Prolonged road life and resistance to extreme heat and humidity in both maintenance and new pavement.

Description

technical field [0001] The invention relates to a double Y type liquid fast-cracking cationic emulsifier for SBS modified asphalt emulsification and its application. The double Y-type liquid fast-cracking cationic emulsifier for SBS modified asphalt emulsification is liquid at normal temperature , has excellent processing and use properties, and has excellent emulsifying properties for SBS modified asphalt, and belongs to the production and processing field of polymer modified emulsified asphalt. Background technique [0002] As a by-product of petroleum refining, asphalt is widely used in road construction and maintenance, and waterproof membranes in buildings due to its good waterproof, corrosion resistance, and excellent adhesion to various road materials and building materials such as stone and cement. And waterproof coatings, ships and oil fields, chemical industry and other fields of heavy anti-corrosion. Due to the high freezing point of asphalt, it usually needs to ...
