Abstract
(EN) The present invention relates to the technical field of construction additives, and in particular, to a high-early-strength cement dispersion polymer and a preparation method therefor. The high-early-strength cement dispersion polymer comprises: a) an ester-containing polymer comprising a polymer or copolymer derived from monomers, the monomers comprising: 1) an unsaturated carboxylic ester monomer; and 2) at least one of an unsaturated acid monomer and an unsaturated silane monomer; b) carboxymethyl starch; and c) methoxypolyethylene glycol. According to the high-early-strength cement dispersion polymer, by using a method of first performing low temperature copolymerization and then performing high temperature esterification, the damage of double bonds of a reaction monomer is reduced, the copolymerization degree is increased, the produced cement dispersion polymer is high in water-reducing rate, the concrete workability can be improved and the early strength of concrete can be increased, and therefore, the compactness of the concrete is improved, and the cracking risk of the concrete is reduced; moreover, the operation process is simple, and large-scale industrial production is facilitated.
(FR) La présente invention relève du domaine technique des additifs de construction, et concerne en particulier un polymère de dispersion de ciment à haute résistance initiale et un procédé de préparation associé. Le polymère de dispersion de ciment à haute résistance initiale comprend : a) un polymère contenant un ester comprenant un polymère ou un copolymère dérivé de monomères, les monomères comprenant : 1) un monomère d'ester carboxylique insaturé ; et 2) au moins l'un d'un monomère d'acide insaturé et d'un monomère de silane insaturé ; b) du carboxyméthyl amidon ; et c) du méthoxypolyéthylène glycol. Selon le polymère de dispersion de ciment à haute résistance initiale, en utilisant un procédé de première mise en œuvre d'une copolymérisation à basse température, puis en réalisant une estérification à haute température, l'endommagement des doubles liaisons d'un monomère de réaction est réduit, le degré de copolymérisation est augmenté, le polymère de dispersion de ciment produit présente un taux de réduction d'eau élevé, l'aptitude au façonnage du béton peut être améliorée et la résistance initiale du béton peut être augmentée, et par conséquent, la compacité du béton est améliorée, et le risque de fissuration du béton est réduit ; de plus, le procédé de fonctionnement est simple, et la production industrielle à grande échelle est facilitée.
(ZH) 建筑外加剂技术领域，特别涉及一种早强型水泥分散聚合物及其制备方法，其中，所述早强型水泥分散聚合物包含：a)含酯基的聚合物，所述含酯基的聚合物包含得自单体的聚合物或共聚物，所述单体包含：1)不饱和羧酸酯单体；以及2)不饱和酸单体、不饱和硅烷单体中的至少一种；以及b)羧甲基淀粉；和c)聚乙二醇单甲醚。早强型水泥分散聚合物采用先低温共聚后高温酯化的方法，减少了反应单体双键的破坏，共聚程度提高，生产的水泥分散聚合物减水率高，可改善混凝土和易性和提高混凝土的早期强度，从而提高混凝土的密实度和降低混凝土的开裂风险；同时，操作工艺简单，利于大规模工业化生产。
