Abstract
The invention discloses a kind of preparation method of enhanced rubber powder modified concrete asphalt mortar, first rubber powder and emulsifying agent are added to the water jointly and are uniformly mixing to obtain rubber powder emulsion, then add in rubber powder emulsion and emulsify after silane coupler KH 570 is mixed with asphalt high-temperature, tetraethyl orthosilicate is added dropwise again carries out solgel reaction in situ and obtain rubber powder modified asphalt emulsion, enhanced rubber powder modified concrete asphalt mortar is obtained after being well mixed with the raw material such as portland cement, quartz sand.Cement asphalt mortar produced by the present invention both has excellent elasticity and weatherability, there is higher mechanical strength and stability again, and performance is good, and durability is strong.
Description
Technical field
The present invention relates to cement mortar material technical field, more particularly to a kind of enhanced modifying rubber powder cement pitch sand
The preparation method of slurry.
Background technology
Cement asphalt mortar is that one kind is made up of raw material such as cement, emulsified asphalt, fine aggregate, water and a variety of additives,
Through hydrated cementitious hardening and a kind of new organic/inorganic composite material formed by the cementing collective effect of pitch demulsification, in high-speed iron
Elastic insert is served as in the ballastless track structure of road, plays a part of filling adjustment, load power transmission.With China's high-speed iron in recent years
The fast development of road infrastructure, cement asphalt mortar has also obtained increasing concern.Due to emulsified asphalt exist it is weather-proof
Property difference defect, and improve elastic performance it is limited, have research will have high resiliency and wide material sources, cheap rubber
Rubber powder is compounded to improve the weatherability of mortar with emulsified asphalt.CN200710133454 is disclosed for cement asphalt mortar
Rubber powder-asphalt emulsion, by the way that rubber powder and emulsified asphalt are carried out into the weatherability that compounding improves elastic mortar.However,
The mechanical strength of rubber powder modified concrete asphalt mortar is relatively low, influences its performance and durability, it is necessary to make improvements.
The content of the invention
The object of the invention is exactly that there is provided a kind of enhanced modifying rubber powder cement pitch in order to make up the defect of prior art
The preparation method of mortar.
The present invention is achieved by the following technical solutions：
A kind of preparation method of enhanced rubber powder modified concrete asphalt mortar, comprises the following steps：
（1）By 2-4 parts by weight anionic emulsifier, 0.5-1 parts by weight nonionic emulsifier, 0.1-1 parts by weight stabilizers
600-1000r/min stirrings 5-10min in 20-30 parts by weight water is added, 5-15 parts by weight of rubber powder is then added and turns in same
Speed is lower to be continued to stir 20-30min, obtains rubber powder emulsion；
（2）1-2 parts by weight Silane coupling reagent KH-570 is added in 30-40 parts by weight pitches in 110-160 DEG C of mixed processing 5-
10min, then adds step（1）60-70 DEG C of high-speed stirred 20-30min in obtained rubber powder emulsion, being cooled to after normal temperature will
PH is adjusted to 8-8.5, and 3-5 parts by weight tetraethyl orthosilicate and stirring reaction 12-24h is slowly added dropwise, and obtains rubber powder-modified pitch breast
Liquid；
（3）By step（2）Obtained rubber powder-modified pitch emulsion and 100-150 parts by weight silicate cement, 150-200 weights
Measure part quartz sand, 0.5-1 parts by weight water reducer, 0.05-0.1 parts by weight defoamer, 20-30 parts by weight water to be well mixed, obtain
Enhanced rubber powder modified concrete asphalt mortar.
The anionic emulsifier is in neopelex, sodium lignin sulfonate, lauryl sodium sulfate
It is one or more of.
The nonionic emulsifier is the one or more in NPE, Tween-80, Arlacel-80.
The stabilizer is the one or more in hydroxyethyl cellulose, carboxymethyl cellulose, polyvinyl alcohol.
The rubber powder is 100-200 mesh.
The water reducer is polycarboxylic acids dehydragent.
The defoamer is polysiloxane-based defoamer.
It is an advantage of the invention that：
Rubber powder and emulsifying agent are first added to the water by the present invention jointly is uniformly mixing to obtain rubber powder emulsion, then will be silane coupled
Agent KH-570 is added in rubber powder emulsion after being mixed with asphalt high-temperature and emulsified, then tetraethyl orthosilicate is added dropwise carries out colloidal sol in situ-solidifying
Glue is reacted, and inorganic nano layer is introduced on emulsified asphalt surface, rubber powder-modified pitch emulsion is obtained, with portland cement, quartz
Enhanced rubber powder modified concrete asphalt mortar is obtained after the raw materials such as sand are well mixed.The present invention passes through newborn to rubber powder-pitch
Inorganic constituents nano silicon is introduced in liquid, the three-dimensional netted knot of rubber-silica-pitch can be formed in mortar
Structure, with certain physical and chemical stability, there is good enhancing effect to mortar, has made obtained cement asphalt mortar both
With excellent elasticity and weatherability, there are higher mechanical strength and stability again, performance is good, and durability is strong.
