Problems solved by technology

[0005] In the prior art, most of its development methods are to introduce functional monomers and acrylic monomers for multi-component copolymerization, graft copolymerization, or add cross-linking agents to change the linear structure into a network structure, thereby improving the heat and cold resistance of the coating film. , and the antibacterial performance is very poor

Abstract

The invention relates to a preparation method of a fluorine containing antibacterial leather finishing agent, which is prepared through the reactions among the following raw materials: hexafluoroacetylacetone-cyclooctadiene copper, methyl 3-methoxyacrylate, vinylidene fluoride, toluene-2,4-diisocyanate, and a tetramethyl guanidine trifluoromethane sulfonate ionic liquid.

Description

technical field [0001] The invention relates to a preparation method of a finishing agent, in particular to a preparation method of a fluorine-containing leather antibacterial finishing agent. Background technique [0002] Acrylic resin is currently the most widely used leather finishing material in the world, and its annual output accounts for 70% of the leather finishing agent. From the perspective of production cost, process and comprehensive performance, acrylic resin as a finishing material is more Other chemical materials can be said to have many advantages, but there is nothing perfect in the world, and its only defect is that it is hot, sticky and brittle, so that its use is limited by climatic conditions. Since 1987, the American Rohm and Hass company has successively developed new products, the second generation of acrylic resin (sGA), which has made a breakthrough in hot-sticky and cold-brittle. Subsequently, my country has also achieved certain results in the mo...
