High copolymer pulp components for composite inorganic nanoparticles

Abstract

The invention discloses a component of copolymer using in complex inorganic nanoparticles and relates to the pulp and sizing production and process technology of spinning warp sizing and paper-making glue processes. The said copolymer is a kind of ionic acrylic polymers and it is made of ionic monomers, hydrophilic monomers, acrylate monomers and few other monomers by free radical copolymerization reaction, or is made of polyacrylamide as the raw material by macromolecular chemical reaction. The said copolymer is used to prepare a new slurry component which substantial replaces PVA in the spinning warp sizing and paper-making glue processes. The said slurry contains of the mixture in a proportion of 0.1-50 % of copolymer, 0.1-50 % inorganic nanoparticles and residual water.

Description

technical field

[0001] The invention relates to the size used in the fields of textile warp yarn sizing and papermaking surface sizing, and the preparation and processing technology of the size, in particular to a high-efficiency and environment-friendly new size. Background technique

[0002] Starch or modified starch, PVA and other sizing components have been widely used in warp sizing and papermaking surface sizing. In the process of textile warp sizing, in order to improve the strength and wear resistance of sizing, reduce the rate of warp yarn breakage, and improve the production efficiency of cloth machines, it is usually necessary to mix a large amount of PVA sizing components while using modified starch sizing ; Surface sizing materials in the paper industry are also mainly modified starch and PVA. In view of the fact that PVA is difficult to biodegrade in the natural environment, long-term use will cause serious pollution to the water ecol...
