The formula is reasonable in design, the stability of the CA mortar can be effectively improved, and the technical performance of the CA mortar is improved.
Description
Technical field
The present invention relates to a kind of CA mortar stablizer, belong to the manufacturing technology field of cement asphalt mortar with subsidiary material.
Background technology
Cement asphalt mortar (being called for short the CA mortar) is the key components of plate-type slag-free orbit in inter-city high-speed rail, city high speed light rail, the city underground etc., mainly is made up of cement, bitumen emulsion, fine aggregate etc.Perfusion CA mortar in the space that the plate-type slag-free orbit construction is reserved between pre-track plate and concrete bed the time has rigidity and elastic filling bed course concurrently with what form homogeneous, can play the dual function of adjusting the track geometry precision and absorbing the vibratory impulse energy.Because the consistency in the existing CA mortar between each component is poor, cause the poor stability of system, layering has easily influenced intensity and other performances of CA screed after the sclerosis.Therefore, the consistency of improving between each component of CA mortar is a key that promotes CA mortar technical feature.
Summary of the invention
It is reasonable to the purpose of this invention is to provide a kind of formulating of recipe, can effectively improve the stability of CA mortar, improves the CA mortar stablizer of CA mortar technical feature.
The present invention is a kind of CA mortar stablizer, it is characterized in that comprising the water-soluble polymers monomer, polymer latex, cationic emulsifier, water etc., the composition of each component is respectively by weight percentage: water-soluble polymers monomer 1.2~1.5%, polymer latex 8~10%, cationic emulsifier 1~1.3%, all the other are water, the weight percent summation of each component is 100%.
Described water-soluble polymers monomer can be polyacrylamide.
Described polymer latex can be SBR latex.
Described cationic emulsifier can be lauryl amine, tetradecylamine, hexadecylamine, dodecyl dimethyl benzyl ammonia chloride, tetradecyl benzyl dimethyl ammonium chloride, hexadecyldimethyl benzyl ammonium benzyl ammonia chloride, the soybean oleyl amine, the mixture of any one or more of coconut oleyl amine etc.To promote the emulsification of polymer latex.
Described CA mortar can be 2~6% of CA mortar weight with the add-on of stablizer in the CA mortar.
The mechanism of modification of CA mortar of the present invention is mainly: polymkeric substance (water-soluble polymers monomer, polymer latex) homodisperse in bitumen emulsion, cement gel, thereby make hydration more become perfect, formed the network that runs through mutually with pitch, cement gel, increased the cohesive force between them, improve the intensity and the stability of CA mortar, reduced the material separation degree of CA mortar.
