Macromolecular soft magnetic door gauze element and preparation method thereof

Abstract

The invention discloses a macromolecular soft magnetic door gauze element. The gauze element is prepared from the following raw materials in parts by weight: 0.1-0.2 part of methylbenzene diisocyanate, 7-10 parts of 0.1-0.15mol / l ammonium persulphate aqueous solution, 70-74 parts of phenylamine, 2-3 parts of 0.5-0.6mol / l hydrochloric acid, 1-2 parts of carbon nano tubes, 140-160 parts of 80-90% formic acid, 40-50 parts of nylon 6, 0.6-1 part of sodium lauroyl sarcosine, 1-2 parts of polyvinylpyrrolidone, 0.4-0.5 part of polyacrylamide, 2-3 parts of polylactic acid, 2-3 parts of allyl alcohol, 0.1-0.2 part of butyltin trioctoate, 0.5-1 part of tetrabutylammonium bromide and 0.2-0.4 part of sucrose acetate isobutyrate. The gauze element disclosed by the invention is added with polylactic acid, polyvinylpyrrolidone and polyacrylamide, can effectively improve flexibility of monofilament fibers and also can promote dispersion of filler in resin and improve stability strength of the finished product.

Description

technical field [0001] The invention relates to the technical field of gauze, in particular to a polymer soft magnetic door gauze and a preparation method thereof. Background technique [0002] Although the polyaniline conductive fiber has good conductivity, the stability of the polyaniline solution is poor. When the solid concentration exceeds 6%, the spinning solution will produce gel after a short period of time. When the solution spinning technology is used to form the fiber At the required concentration (>10%), the formation of gel hinders the use of the solution, it is very difficult to spin with it, the requirements for solvent and spinning equipment are high, and the physical and mechanical properties of the obtained fibers are poor, the strength Low, high brittleness, it is quite difficult to carry out subsequent processing such as spinning and weaving. In order to improve the physical and mechanical properties of fibers and improve their applicability, polyanil...
