Problems solved by technology

However, in order to meet the bactericidal effect of the marker pen, it is necessary to add too much bactericide to the ink, which will lead to the phenomenon that the content of bactericidal preservatives (such as EN71-9) in the water-based marker pen exceeds the standard (exceeding the EU limit requirements), making the mark Pen products cannot be sold in the market

preparation example Construction

[0021] The invention provides a kind of preparation method of antibacterial and mildew-proof fiber nib, comprising the following steps:

[0022] The fiber is sequentially combined, shaped, dipped, cured, cut and ground to form a fiber pen;

[0023] The components of the glue solution used in the dipping are adhesives, organic solvents and anti-mildew bactericides.

[0024] In the present invention, unless otherwise specified, the required preparation materials are commercially available products well known to those skilled in the art.

[0025] In the present invention, the fiber preferably includes polyester, nylon or acrylic; the fineness of the fiber is preferably 100-600D, more preferably 200-500D, even more preferably 300-400D. In the present invention, the type of the polyester is preferably DTY, and the crimp shrinkage of the DTY is preferably 15-30%.

[0026] In the present invention, the diameter of the fiber tip is preferably 2 to 5 mm, more preferably 3 to 4 mm, an...

Embodiment 1

[0038] Fiber: polyester filament DTY, 300D / 96F, 200kg; the crimp shrinkage of the DTY is 15%;

[0039] Glue: polyol (glycerol: trimethylolpropane = 2:1): 10kg, isocyanate TDI 15kg, ethyl acetate: 55kg; Wanliqing PL-9800.1kg;

[0040] Determine the number of fiber strands according to the size and diameter of the required pen head, and then combine the fibers, place the obtained fibers in a heat-setting tube, and set them at 215°C for 1 minute; soak the fibers obtained after setting in the above glue dipping in the liquid for 1.0min; the fibers obtained by dipping were cured in a curing box at 130°C for 20min by traction; the obtained cured fibers were cut into bars with a length of 1m, and then according to the actual length of the pen Divide into nib rods of about 3cm, and then grind the obtained nib rods into round heads, pointed heads or axes; wash and dry the formed nibs in sequence to obtain antibacterial and anti-mildew fiber nibs (2.5mm in diameter) .

Embodiment 2

[0042] Fiber: polyester filament DTY, 150D / 96F, 200kg; the crimp shrinkage rate of said DTY is 15%;

[0043]Glue: polyols (ethylene glycol: propylene glycol = 1:1): 10kg, isocyanate polyurethane MDI15kg, ethyl acetate: 60kg; Wanliqing PL-9800.1kg;

[0044] According to the size and diameter of the required pen head, determine the number of strands of fiber strands, then strand the fibers, place the obtained fibers in a heat-setting tube, and set them at 220°C for 1 min; soak the fibers obtained after setting in the above-mentioned Dipping in the glue solution for 1.0min; the fibers obtained by dipping were cured in a curing box at 135°C for 20min by traction; the obtained cured fibers were cut into bars with a length of 1m, and then according to the actual situation of the pen The length of the pen is cut into about 3cm of the nib bar, and then the resulting nib bar is ground into a round head, pointed head or axe; the resulting formed nib is washed and dried in turn to obtain...

Abstract

The invention belongs to the technical field of pen manufacturing, and particularly relates to an antibacterial and mildew-proof fiber pen point and a preparation method thereof. Fibers are sequentially subjected to strand combining, shaping, gum dipping, curing, cutting and grinding forming, and then the fiber pen point is obtained; and a glue solution adopted by the gum dipping comprises the following components of an adhesive, an organic solvent and a mildew-proof bactericide. According to the antibacterial and mildew-proof fiber pen point and the preparation method thereof, the mildew-proof bactericide is added into the glue solution and permeates into the fiber pen point, the obtained fiber pen point contains the sterilization component (the existing pen point does not contain the sterilization component), then the dosage of the bactericide in the matched ink can be reduced, so that the limit requirement of the European Union on EN71-9 is met; and the prepared antibacterial and mildew-proof fiber pen point is long in effective antibacterial time, and the antibacterial effect can be maintained in the whole service life of a water-based marking pen.

Description

technical field [0001] The invention relates to the technical field of pen making, in particular to an antibacterial and anti-mildew fiber pen tip and a preparation method thereof. Background technique [0002] According to the writing medium used, marker pens can be divided into oil-based marker pens and water-based marker pens. Traditional oily marker ink contains about 75% volatile organic solvents, such as the USP5279653 exemplified marker ink contains 75% ethanol, after writing, the solvent volatilizes and pollutes the surrounding environment. In order to reduce volatile organic compounds, water-based markers are widely used. [0003] Water-based marker ink contains functional additives such as alcohols, which can cause problems such as mildew of the marker pen. In order to prevent corrosion and mildew, bactericidal preservatives are usually added to the ink of the existing water-based marker pen, such as the example of USP7455725B2 The preservatives NUOSEPT 95 and Ka...
