POLYCARBOXYLIC ACID WATER-REDUCING AGENT WITH HIGH ADAPTABILITY TO TEMPERATURE AND METHOD FOR PREPARING THE SAME
The present invention discloses a polycarboxylic acid water-reducing agent with high adaptability to temperature and a preparation method for preparing the same. The polycarboxylic acid water-reducing agent is prepared by introducing an unsaturated macromonomer D with a temperature-sensitive side chain which could be bonded to the backbone of the polycarboxylic acid through free radical polymerization. The polycarboxylic acid water-reducing agent prepared by the invention has an adsorption group density that can be automatically adjusted with the change of ambient temperature, and thereby shows similar dispersing capability and dispersion retention capability at different ambient temperatures, demonstrating high adaptability to different ambient temperatures. It can be used in a larger temperature range with a constant dosage, which is beneficial to further popularization and application of the polycarboxylic acid water-reducing agent in regions of different climates.
