Problems solved by technology

[0006] Aiming at the unsatisfactory washing fastness of the current water-based pigment inkjet printing ink on fabrics, the present invention provides an organofluorine-modified polyacrylate nanoemulsion and a preparation method thereof. The organofluorine-modified polyacrylate emulsion particles The diameter is at the nanometer level, and the degree of crosslinking inside the emulsion particles is relatively high. When the film is formed on the surface of the fabric, the crosslinking does not cause demulsification and film formation, and it is still distributed in the form of hydrophobic nanoparticles in another polyacrylate emulsion and polyurethane. Composite film formed by emulsion

Embodiment 1

[0028] A kind of organic fluorine modified polyacrylate nanoemulsion, its synthetic method is: with 12.3g methyl methacrylate (MMA), 2.7g hexafluorobutyl methacrylate (HFBM), 0.6g emulsifying agent (by Xiao trouble 465. Sodium dodecyl sulfate (SDS) is mixed at a mass ratio of 1:1), 0.5 g of ethylene glycol dimethacrylate is added to 20 g of water, stirred at a high speed of 2500 rpm, and pre-emulsified for 30 minutes to obtain a pre-emulsified monomer. lotion. Then, 30 g of monomer pre-emulsion was added into the three-necked flask, the temperature was raised to 80° C., and 4 g of initiator potassium persulfate aqueous solution (concentration: 0.82%) was added to react for 30 min. Then use the dropping funnel to drop 6g initiator potassium persulfate aqueous solution (concentration 0.82%) and the pre-emulsion of the remaining monomers into the three-necked bottle simultaneously and slowly (10 drops / min), react for 2h, and obtain the required The organic fluorine-modified poly...

Abstract

The invention provides an organic fluorine modified polyacrylate nanometer emulsion and a nanometer composite adhesive. The organic fluorine modified polyacrylate nanometer emulsion is characterized by being synthesized through the method comprising the steps that 10-15 parts by weight of methyl methacrylate, 2-4 parts by weight of hexafluorobutyl methacrylate, 0-1 part by weight of emulgator and 0-1 part by weight of ethylene glycol dimethacrylate are added into 15-25 parts by weight of water, stirring is carried out, pre-emulsification is carried out for 25-35 min, and a monomer pre-emulsion is obtained; then, 25-35 parts by weight of the monomer pre-emulsion is added into a reaction container, the temperature is increased to 75-85 DEG C, 2-5 parts by weight of the initiator potassium peroxodisulfate water solution with the concentration being 0.7-0.9% is added, a reaction is carried out for 25-35 min, 4-8 parts by weight of the initiator potassium peroxodisulfate water solution with the concentration being 0.7-0.9% and residual monomer pre-emulsion are dropwise added into the reaction container at the same time, a reaction is carried out for 1-3 h, and therefore the needed organic fluorine modified polyacrylate nanometer emulsion is obtained. The washing color fastness of textiles can be improved by means of the organic fluorine modified polyacrylate nanometer emulsion.

Description

technical field [0001] The invention relates to an organic fluorine-modified polyacrylate nanoemulsion and a nanocomposite adhesive. Background technique [0002] Traditional screen and rotary screen printing operations are complex and tedious, and cannot meet the requirements of high quality, small batches, diverse patterns, and individualization, while digital inkjet printing technology gets rid of the simulation of traditional printing color separation, plate making, and net making. The method has the obvious advantages of convenient operation, no pollution, low energy consumption, and high return, bringing unprecedented development opportunities to the textile printing and dyeing industry. Digital inkjet printing is to input the required printing pattern into the computer in digital form, after computerized printing color separation, scanning and editing, the digital inkjet printing machine controlled by the computer directly sprays the printing ink onto the fabric preci...
