Abstract
The invention discloses a polycarboxylate water reducing agent and a preparation method thereof. The water reducing agent is prepared from the following main components in parts by weight: methyl allyl polyethenoxy ether, sodium methallyl sulfonate, maleic anhydride, acrylamide, propenoic acid, hydrogen peroxide, mercaptoacetic acid and purified water. The polycarboxylate water reducing agent has the advantages that the water reducing rate reaches up to 45%, the high water reducing and slump loss resisting requirements of concrete can be better met, the sensitivity to temperature is low, the adaptability to cement is strong, the preparation process is simple, and the preparation is easy.
Description
Technical field
The present invention relates to a kind of water reducer and preparation method thereof, particularly a kind of polycarboxylate water-reducer and preparation method thereof.
Background technology
Polycarboxylate high performance water-reducing agent (liquid) is the ordinary water-reducing agent of representative and the third generation high-performance water reducing agent that grows up after being the high efficiency water reducing agent of representative with naphthalene continue wooden calcium, is forefront, scientific and technological content is the highest, application prospect is best, over-all properties is optimum a kind of high efficiency water reducing agent in the world at present.PC polycarboxylate high performance water-reducing agent represents the leading water reducer product of world today's technology content.Through showing with similar products at home and abroad Performance comparision, PC polycarboxylate high performance water-reducing agent all reaches current international most advanced level in technical performance index, cost performance.
But the water-reducing rate of existing poly carboxylic acid series water reducer normally 35%-40%, can not meet concrete diminishing and guarantor preferably and to collapse requirement, to temperature sensitive, and cement adaptability is not strong.
Summary of the invention
