Description
Technical field
The present invention relates to anti-mud agent technical field, especially a kind of high-performance polycarboxylic acids water reducing agent anti-mud agent and its preparation
Method.
Background technique
Recent decades are prepared high with the continuous development of Concrete and construction technology using poly carboxylic acid series water reducer
Performance concrete using more and more extensive, it has also become the development trend of concrete.Poly carboxylic acid series water reducer is due to volume
It is small, water-reducing rate is high, cement adaptability is good, it is slump-retaining can excellent, chloride ion content and alkali content is low, shrinking percentage is small and resistance to
The environmentally protective advantages such as long performance is good, be widely used in room build in infrastructure construction engineering.But in practical application mistake
Cheng Zhong, discovery sand clay content are larger to the adverse effect for mixing polycarboxylate water-reducer concrete.The interlayer structure of soil and institute in sand
The high volence metal ions such as the magnesium ion, the aluminium ion that include can largely adsorb polycarboxylate water-reducer molecule, and water-reducing agent is made to lose activity.
In recent years, natural sand resource scarcity, it is a large amount of high containing mud with the quickening of Process of Housing Industrialization and increasing for infrastructural project
The sand of amount is used directly in concrete, so that the workability for mixing the fresh concrete of polycarboxylate water-reducer is deteriorated, the slump is protected
Ability decline is held, or even influences the intensity and durability of concrete.
There is presently no a kind of effective methods to solve the above problems, and can only pass through the volume of raising polycarboxylate water-reducer
It solves, improves the cost of concrete, while also will increase the trouble of other techniques.Although and having claimed anti-mud on the market
The anti-mud agent of agent, either powder liquid is all one or more kinds of formulas of water-reducing agent actually, although equally matching
In the case of can improve water-reducing rate, but easily bleeding, slump-loss is fast, materials increased costs.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of high-performance polycarboxylic acids water reducing agent anti-mud
Agent, in mixing concrete, anti-mud agent can carry out Preferential adsorption or selective absorption to the mud in sand, reduce soil to diminishing
The absorption of agent molecule will have important meaning to the development of polycarboxylate water-reducer to sufficiently keep the performance of polycarboxylate water-reducer
Justice.
