Abstract
The invention discloses a kind of PMA MPEG type poly carboxylic acid series water reducer, belong to chemical field.It is prepared from by following raw material: polymaleic anhydride (PMA) 40 60 parts, poly glycol monomethyl ether (MPEG) 100 110 parts, Polyethylene Glycol (PEG) 10 20 parts, concentrated sulphuric acid 0.06 0.10 parts, toluene 70 80 parts.Synthesis step of the present invention is simple, and product comb shaped structure is obvious, can be greatly increased concrete dispersibility.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of PMA-MPEG type poly carboxylic acid series water reducer
Background technology
Polycarboxylic acid series high efficiency water reducing agent be continue with the wood calcium first generation water reducer as representative and with naphthalene system as representative second
For the third generation high-performance water reducing agent grown up after water reducer.The water-reducing mechanism brand-new due to it and distinctive molecule knot
Structure, it has compared with conventional naphthalene system and melamine system second filial generation high efficiency water reducing agent, and volume is low, reinforced effects good, flowing retentivity
Good, loss of slump is low, lower shrinkage, have certain amount of air entrainment and the plurality of advantages such as get along with environmental friendliness, substantially meet
The concrete works particularly high performance concrete performance requirement to water reducer, becomes the representative product of third generation high efficiency water reducing agent
Product.Additionally, polycarboxylate high performance water-reducing agent product has the implication of seriation.Owing to it is mainly existed by unsaturated monomer
Copolymerization under the effect of initiator, by the side chain graft with active group to obtaining on main polymer chain, the most different
Carboxylic unsaturated monomer, the different activated monomers containing functional functional group, and compound mode different between monomer, no
Same synthetic technology route, can obtain the multiple carboxylic acid copolymer with different structure and performance characteristics.
Summary of the invention
For above-mentioned, it is an object of the invention to provide one.
