Abstract:
(EN) A crosslinking modified type water-soluble solid polyacrylamide. The crosslinking modified type water-soluble solid polyacrylamide is at least formed by means of the chain polymerization and copolymerization of six kinds of monomers, such as a nonionic monomer A, a nonionic monomer B, a crosslinking agent, a modifying monomer, a cationic monomer, and an anionic monomer. The present invention resolves the problems existing in a water-soluble type amphoteric polyacrylamide product that the molecular weight is low, the content of an effective substance is low, storage stability is poor, and shelf life is short; a higher molecular weight product can be obtained, wherein the content of the effective substance is high, transportation costs are low, and the product is not easy to hydrolyze and mildew. The crosslinking modified type water-soluble solid polyacrylamide can be used for the enhancement and/or modification of a natural fiber material or a semi-synthetic fiber material, promotes the improvement of drainage performance, and also helps strength enhancement.
(FR) L'invention concerne un polyacrylamide solide hydrosoluble de type modifié par réticulation. Le polyacrylamide solide hydrosoluble de type modifié par réticulation est au moins formé au moyen de la polymérisation en chaîne et de la copolymérisation de six sortes de monomères, tels qu'un monomère non ionique A, un monomère non ionique B, un agent de réticulation, un monomère de modification, un monomère cationique et un monomère anionique. La présente invention résout les problèmes existant dans un produit polyacrylamide amphotère de type hydrosoluble selon lesquels le poids moléculaire est faible, le contenu d'une substance efficace est faible, la stabilité au stockage est faible et la durée de conservation est courte. Un produit de poids moléculaire plus élevé peut être obtenu. Le contenu de la substance efficace est élevé, les coûts de transport sont faibles et le produit ne s'hydrolyse et ne moisit pas facilement. Le polyacrylamide solide hydrosoluble de type modifié par réticulation peut être utilisé pour l'amélioration et/ou la modification d'un matériau fibreux naturel ou d'un matériau fibreux semi-synthétique, favorise l'amélioration des performances de drainage et contribue également à l'amélioration de la résistance.
(ZH) 交联改性型水溶性固体聚丙烯酰胺,其至少由非离子单体A、非离子单体B、交联剂、改性单体、阳离子单体以及阴离子单体六类单体连锁聚合共聚而成,解决水溶液型两性聚丙烯酰胺产品存在的分子量低、有效物含量低、存储稳定性差、保质期短等问题,可获得更高分子量产品,有效物含量高,运输成本低,不易水解,不易发霉。所述交联改性型水溶性固体聚丙烯酰胺可用于天然纤维材料或者半合成纤维材料的增强和/或改性,对滤水性能的改善有促进作用,而且对强度提升也有帮助。
