Abstract
(EN)
Provided are a polycarboxylic acid water-reducing agent with high adaptability to temperature and a preparation method therefor. The polycarboxylic acid water-reducing agent is prepared by introducing an unsaturated macromonomer D having a temperature-sensitive side chain in the synthetic process of the polycarboxylic acid water-reducing agent, and binding to a polycarboxylic acid main chain by means of free radical polymerization due to an unsaturated double bond, and on the other hand, the polycarboxylic acid water-reducing agent contains the temperature-sensitive side chain. The density of adsorption groups of the prepared polycarboxylic acid water-reducing agent can be automatically adjusted with the change in ambient temperature, and accordingly, the polycarboxylic acid water-reducing agent has approximate dispersion and dispersion retention capacities in different ambient temperatures, and has high adaptability to different ambient temperatures, and can be used in a large temperature range with the amount of admixture unchanged, facilitating further promotion and application of the polycarboxylic acid water-reducing agent in different climatic regions.

L'invention concerne un agent réducteur d'eau à base de poly(acide carboxylique) présentant une haute adaptabilité à la température et un procédé de préparation s'y rapportant. L'agent réducteur d'eau à base de poly(acide carboxylique) est préparé par introduction d'un macromonomère insaturé D ayant une chaîne latérale sensible à la température dans le processus de synthèse de l'agent réducteur d'eau à base de poly(acide carboxylique) et se liant à une chaîne principale du poly(acide carboxylique) au moyen d'une polymérisation radicalaire en raison d'une double liaison insaturée et, d'autre part, l'agent réducteur d'eau à base de poly(acide carboxylique) contient la chaîne latérale sensible à la température. La densité de groupes d'adsorption de l'agent réducteur d'eau à base de poly(acide carboxylique) préparé peut être automatiquement ajustée avec le changement de température ambiante et, par conséquent, l'agent réducteur d'eau à base de poly(acide carboxylique) a des capacités de dispersion et de rétention de dispersion approximatives à différentes températures ambiantes et a une haute adaptabilité à différentes températures ambiantes et il peut être utilisé sur une large plage de températures, la quantité de mélange restant inchangée, ce qui facilite encore la promotion et l'application de l'agent réducteur d'eau à base de poly(acide carboxylique) dans différentes régions climatiques.

提供了一种对温度具有高适应性的聚羧酸减水剂及其制备方法。聚羧酸减水剂通过在聚羧酸减水剂的合成过程中引入一种具有温敏性侧链的不饱和大单体D,其含有不饱和双键,可以通过自由基聚合结合到聚羧酸主链上,另一方面其含有温敏性侧链制得。制得的聚羧酸减水剂的吸附基团密度可随环境温度的变化而自动调节,进而在不同的环境温度下体现出接近的分散及分散保持能力,体现出对不同环境温度的高适应性,在掺量不变的情况下可以在较大的温度区间范围内使用,有利于聚羧酸减水剂在不同气候地区的进一步推广应用。
