Abstract

A stabilizer for CA mortar belongs to the technical field of manufacturing of auxiliary materials for cement asphalt mortar, and comprises water-soluble polymer monomers, polymer latex, cationic emulsifier, water and the like, wherein the components in percentage by weight are as follows: 1.2-1.5% of water-soluble polymer monomer, 8-10% of polymer latex, 1-1.3% of cationic emulsifier and the balance of water, wherein the total weight percentage of the components is 100%; the addition amount of the additive in the CA mortar is 2-6% of the weight of the CA mortar. 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

A kind of CA mortar stablizer
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.
Embodiment
Below will have the composition of CA mortar material Comparative Examples and 12 embodiment each components of the present invention now and detect after the basic mechanical design feature contrast be listed as follows, to further specify excellent properties of the present invention.
The present invention is not limited to following embodiment, when practical application, can require and use occasion according to different performance, selects the different proportionings among the following embodiment, or the different proportionings except that following each embodiment, but does not all limit the scope of the invention in any form.
CA mortar of the present invention with the preparation method of stablizer is: water-soluble polymers monomer, cationic emulsifier are joined in 65~80 ℃ the water, stir, can obtain product of the present invention with polymer latex by emulsifying device processing.
The CA mortar material that embodiment 1 (prior art Comparative Examples) selects for use for the present invention: get cement, fine aggregate, aluminium powder, defoamer, AE agent, swelling agent, bitumen emulsion, mixed with polymers emulsion, water mixing stirring, the shared weight part of each raw material is: 100 parts of cement, 220 parts of fine aggregates, 0.025 part of aluminium powder, 0.55 part of defoamer, 0.015 part of AE agent, 10 parts of swelling agents, 180 parts of bitumen emulsions, 25 parts in water.
The add-on of stablizer among the embodiment 2~10 in the CA mortar material is 20 parts.
Table 1: the difference of water-soluble polymers monomer, polymer latex, cationic emulsifier proportioning is to the technical feature influence of CA mortar in the stablizer.
Product of the present invention as can be seen from Table 1 can effectively reduce the material separation degree of CA mortar, the early strength of raising CA mortar.
Water-soluble polymers monomer, polymer latex, cationic emulsifier proportioning are 1.5%: 9.0%: 1.1% among the embodiment 11~13.
Table 2: the difference of stablizer add-on is to the technical feature influence of CA mortar
Figure G2009100990829D00042
As can be seen from Table 2, the optimal addn of product of the present invention is 20~25 parts (100 parts of cement, 220 parts of fine aggregates, 180 parts of bitumen emulsions).
In the various embodiments described above, cement is the ordinary Portland cement of strength grade 42.5R.Fine aggregate is clean, hard, does not contain detrimental impurity river sands such as earth and organic matter, and maximum particle diameter is less than 2.5mm, and fineness modulus is 1.4~2.2, moisture ≯ 1%.Aluminium powder is thin phosphorus sprills, 250 orders.Defoamer is the waterborne organic silicon defoamer.The AE agent is a MNC-AE type water reducing type air entrapment agent.Swelling agent is a UEA type cement expansive material.Bitumen emulsion is the common cation bitumen emulsion.
