Background technology
Water-reducing agent is a kind of under conditions of keeping concrete flowability essentially identical, can reduce the additional of mixing water amount
Agent is the concrete admixture studied and be most widely used at present.Incorporation water-reducing agent, which can improve, in use newly mixes
Workability, the mobility of concrete, and the intensity of concrete can be improved, extend the service life of concrete component, therefore diminishing
Agent is indispensable a kind of additive in concrete.Existing aliphatic high-efficiency water reducing agent is mixed for newly mixing currently on the market
When in solidifying soil, all different degrees of shows yellowish, and easy bleeding isolation, the disadvantages feature such as concrete workability difference cannot
It directly applies in the higher clear-water concrete of the appearance requirements such as municipal works, highway, railway.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of water-reducing rate height, workability is good, Slump Time losing of Large is small
Cane molasses fermented waste fluid modified aliphatic high efficiency water reducing agent and its preparation method and application.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of cane molasses fermented waste fluid modified aliphatic high efficiency water reducing agent, the water-reducing agent are counted in parts by weight, including under
State ingredient：
Further, the cane molasses fermented waste fluid modified aliphatic high efficiency water reducing agent, the water-reducing agent is by weight
Number meter, including following compositions：
Further, the activator is selected from oxalic acid, vulcanized sodium, hydrogen peroxide, the one of which in Ozone Water.
Further, the catalyst is selected from least one of ammonium persulfate, potassium peroxydisulfate, benzoyl peroxide.
A kind of preparation method of cane molasses fermented waste fluid modified aliphatic high efficiency water reducing agent, steps are as follows：Under room temperature, to
Cane molasses fermented waste fluid, activator and Waste Sulfuric Acid are put into reaction kettle, are risen to 60 DEG C, are stirred no less than 30 minutes, then
Acetone, sodium sulfite, acrylamide, catalyst, initiator and water are put into, formalin is slowly added dropwise, is dripped off in 2 hours, is dripped
Control temperature drips off heat preservation no less than 1.5 hours at 80-90 DEG C during adding, cooling to be modified up to cane molasses fermented waste fluid
Aliphatic high-efficiency water reducing agent.
A kind of application of cane molasses fermented waste fluid modified aliphatic high efficiency water reducing agent outside cement plus in water-reducing agent.
Further, volume is 1.5~2.0wt% of cementitious material in concrete.
Beneficial effects of the present invention are：
(1) processing is modified to water-reducing agent by cane molasses fermented waste fluid and acrylamide, to improve diminishing
The branch quantity and length of agent, and then the dispersibility and water-reducing rate of water-reducing agent are improved, reduce the slump damage of concrete
It loses, workability is good；The present invention prepares high efficiency water reducing agent for raw material using the waste liquid of cane molasses fermentation alcohol and realizes industrialization,
Not only the fundamental state policy of China's energy-saving and emission-reduction and environmental protection had been met, but also the process lance that prices of raw materials rise is brought can be alleviated
Shield, for pushing the development of China's related industry to be of great significance.
(2) three-waste free discharge in preparation process, safety and environmental protection；Reaction time is short, and preparation method is simple and efficient.
(3) raw material is cheap and easy to get, and production cost is low, great market potential.
