Embodiment 1 Embodiment 6

[0052] A kind of CA mortar emulsion, is the composite emulsion that is formed by mixing cationic emulsified asphalt and chloroprene latex, and each component content (referring to attached table 1) in the composite emulsion is calculated as follows in parts by weight:

[0053] 100 parts by weight of emulsified asphalt

[0054] Neoprene latex 6~10 parts by weight

[0055] The emulsified asphalt in the described CA mortar emulsion is a mixture made of base asphalt, emulsifier, stabilizer, and water through high-speed shearing or grinding by an asphalt emulsifier. The content of each component in the mixture is calculated in parts by weight:

[0056] 55-65 parts by weight of base pitch

[0057] Main emulsifier 1-3 parts by weight

[0058] Auxiliary emulsifier 0.3~0.6 parts by weight

[0059] 35-40 parts by weight of water

[0060] Stabilizer 0.10-0.3 parts by weight.

[0061]The specific proportions of the above-mentioned components in each embodiment are referred to in the ...

Abstract

The invention discloses a CA slurry emulsion and manufacturing method of board-typed non-slag rail, which is composed of 100% cation emulsifying tar and 6-10% polychloroprene latex, wherein the cation emulsifying tar is made of base tar, emulsifier, stabilizer and water through high-speed cutting or grinding in the emulsifier; the base tar is 70# or 90# retransposing road tar; the emulsifier is slow-cracking slow-condensing typed cation emulsion; the polychloroprene latex is cation polychloroprene latex with the rate of oil and water at 35-45:65-55.

Description

Technical field: [0001] The invention relates to a building material and a production method thereof, in particular to a CA mortar emulsion suitable for preparing CA mortar for a slab ballastless track and a production method thereof. Background technique: [0002] With the continuous development of economic construction, my country's railway passenger transport is now developing towards high-speed. Railways with a maximum operating speed of more than 200 kilometers per hour are called high-speed railways. The high-speed railway track puts forward high requirements on the subgrade and ballast bed. In order to ensure the strong stability and high smoothness of the track, it is a trend to adopt the structural form of the slab ballastless track. The elastic layer of the slab ballastless track structure is CementAsphalt mortar, referred to as CA mortar. [0003] At present, CA mortar is still in the test and development stage in China. Chinese patents ZL02139237.4 and ZL2004100...
