The application discloses an organic-inorganic hybrid formaldehyde-free fixing agent and a preparation method and application thereof, and belongs to the technical field of textile auxiliaries. The fixing agent is prepared by using dimethyl diallyl ammonium chloride and methacryloyloxyethyl trimethyl ammonium chloride as reaction monomers, N-vinyl pyrrolidone as an organic modifier, and trisodium phosphate and bismuth nitrate as inorganic modifiers, and the organic-inorganic hybrid crosslinking structure is formed through a polymerization reaction. The preparation method comprises the following steps: pre-complexing bismuth nitrate and citric acid, pre-activating a silane coupling agent, mixing the components, and then performing stage pH regulation, ultrasonic-assisted dispersion, high-temperature curing and other steps. The fixing agent is prepared by means of coordination crosslinking of an organic polymer chain and bismuth ions and covalent connection of a silane coupling agent, so that a double network structure is formed, the wet rubbing fastness and the soaping fastness are significantly improved, the fabric is endowed with antibacterial and ultraviolet resistance functions, the hydrophilicity and the hand feeling are improved, and the fixing agent does not contain formaldehyde, and can be widely applied to post-treatment of textile dyeing.

The application discloses a high-adhesion paint applied to a stainless steel base material, which comprises the following main components in parts by weight: 100-150 parts of a resin composition, 30-50 parts of a color paste, 15-25 parts of a crosslinking agent, 1.5-5 parts of a color fixing agent, 0.8-1.5 parts of a dispersing agent, 0.4-0.8 parts of a leveling agent, 1-2 parts of an accelerator, 0.5-1 part of a weather-resistant agent, 20-40 parts of a filler and 50-75 parts of a solvent; wherein the resin composition is composed of polyurethane, acrylate, water-based polyurethane acrylate resin, organic silicon resin and epoxy resin. The resin composition is composed of polyurethane, acrylate, water-based polyurethane acrylate resin, organic silicon resin and epoxy resin, the resin composition is mixed with the color paste, the crosslinking agent makes the resin crosslink to form a three-dimensional network structure, the adhesion is greatly improved, meanwhile, the color powder molecules can be firmly locked, and the migration and oxidative decomposition of the pigment are prevented.

The present application relates to the field of fixing agent barrel production, especially to a kind of processing device after blow molding of fixing agent barrel.The rotating processing table has multiple processing stations in circular array around rotating processing table, and fixing agent barrel is rotated to pass each processing station in turn for processing;Fixing agent barrel mouth plastic cutting station is provided with cutting knife that is inserted into fixing agent barrel mouth and rotates to cut;Fixing agent barrel mouth polishing station is provided with polishing head that is inserted into fixing agent barrel mouth and polishes.The device can accurately cut and polish the excess plastic inside the blow-molded fixing agent barrel, then size the barrel mouth, and the tightening of the movable clamping jaw is guided by guide block.This design allows 6 pairs of clamping jaws to be controlled by one set of mechanical structure and control program each, simplifying the structure of the equipment and making it more reliable when achieving the desired effect.

This application belongs to the field of organic synthesis and discloses a formaldehyde-free fixing agent based on a triazine-latent isocyanate functional monomer. It is prepared from triazine-latent isocyanate functional monomer (TLI monomer), dimethyl diallyl ammonium chloride (DMDAAC), and diallylamine as raw materials; the mass ratio of the triazine-latent isocyanate functional monomer, dimethyl diallyl ammonium chloride, and diallylamine is 10~30:30~48:10. This fixing agent uses the TLI monomer, which simultaneously integrates a triazine structure, hydroxyl groups, polymeric double bonds, and latent isocyanate groups, as its core. Through copolymerization with DMDAAC and diallylamine, a triple synergistic fixing system of "electrostatic adsorption-hydrogen bond anchoring-covalent crosslinking" is constructed, breaking through the performance bottleneck of traditional formaldehyde-free fixing agents in terms of wet rubbing fastness, and significantly improving the wet rubbing fastness of sensitive colors such as bright red and turquoise blue.
