Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of trimellitic acid class polycarboxylate water-reducer.
Background technology
Poly carboxylic acid series water reducer just can produce preferable diminishing and reinforced effects with it, coagulate concrete when volume is relatively low
Knot time effects is less, slump-retaining the most relative with cement/admixture adaptability preferable, to concrete shrinkage shadow
Ring less (referring to generally increase drying shrinkage not too much), become the naphthalene system that continues, melamine system, fatty family and sulfamate based water reducer it
After water reducer of new generation.Poly carboxylic acid series water reducer molecular structure is comb shape, with more active group on its main chain, such as carboxylic
Acid groups (COOH), sulfonic acid group (SO3H), oh group (OH), poly-ethane oxygen groups ((CH2CH2O)m—R)
Deng.The effect of cement is had nothing in common with each other by each group, as carboxylic acid group has preferable dispersibility and retarding effect；Sulfonic dispersion
Property is good；Hydroxyl not only has deferred action, moreover it is possible to play the effect being impregnated with moistening；Poly-ethane epoxide class group has holding flowing
The effect of property.Molecular Design becomes the first-selected direction of many scholar's research polycarboxylate water-reducer performance characteristics.
Summary of the invention
For above-mentioned, it is an object of the invention to provide a kind of modified version water reducer based on polycarboxylate water-reducer.
