Definitions
- the invention relates to polymer bonded mines for writing, drawing and / or painting equipment.
- Such refills for writing, drawing and / or painting are known in principle.
- Examples include wood pencils and refills for mechanical pencils, such as so-called mechanical pencils or drop pins.
- the mines usually have outside diameters in the range of about 0.3 mm to 6 mm.
- polymer-bound graphite mines are known from DE 38 27 968 C1.
- unfired mines include a polymeric binder, lubricants and fillers.
- a disadvantage of the production of such mines is that at a high filler content of greater than 50 wt .-% Although their writing and painting properties are very good, the viscosity of the lead mass during the extrusion but is very high and thereby required extrusion pressure in the tool and in the extruder assumes very high values.
- the head pressure is about 350 bar. This has a disadvantageous effect, since a larger dimensions of the extruder and a complex equipment is required. But the service life of the machines and tools is also greatly reduced by the high extrusion pressure.
- the object of the invention is therefore to provide a refill for writing, drawing and / or painting, which does not have the disadvantages mentioned and which can be produced with low extrusion pressure.
- the object is achieved for the polymer-bound lead for writing, drawing or painting equipment, especially for pencils or colored pencils, comprising at least one polymeric binder, at least one wax and at least one filler by the mine further 0.1 to 5 parts by weight. % Palm oil.
- the typical fatty acid distribution of palm oil is composed as follows:
- the palm oil causes a more intense color impression of the smear of the mine and improves their sliding behavior when writing.
- At pencil leads shows a rich smear with a high degree of blackening, while color pencil leads show a rich, bright intense hue of the smear.
- the palm oil content of the mine composition is in the range of 0.1 to 5 wt .-%, in particular in the range of 0.5 to 2.5 wt .-%. If the content of palm oil exceeds the above limit of 5% by weight, the miner's strength is disproportionately reduced even when palm oil is used. The mines then tend to crumble or break in use.
- the waxes used are kneadable at 20 0 C, solid to brittle hard, have a coarse to fine crystalline structure, are color translucent to opaque, but not glassy and melt above 40 0 C without decomposition. They are slightly liquid above the melting point and have a strongly temperature-dependent consistency and solubility.
- the polymer-bound mines according to the invention are unfired mines which can be used immediately after the extrusion without further heat treatment or impregnation.
- the polymer-bound mine contains from 15 to 25% by weight of binder
- the at least one binder is formed from at least one polymer from the group consisting of polystyrene (PS), styrene-acrylonitrile (SAN), styrene-butadiene (SB), polyolefins (PO) and acrylonitrile-butadiene-styrene (ABS). It is also possible to use mixtures of two or more binders.
- PS polystyrene
- SAN styrene-acrylonitrile
- SB styrene-butadiene
- PO polyolefins
- ABS acrylonitrile-butadiene-styrene
- the at least one wax is at least one of the group comprising stearates, montan waxes, amide waxes, paraffins.
- the at least one wax is formed from calcium stearate or comprises calcium stearate.
- the at least one filler is formed from at least one filler of the group comprising graphite, carbon black, hexagonal boron nitride, phyllosilicates, chalk, barite, colored pigments, achromatic pigments.
- coloring fillers For pencil leads, in particular graphite or graphite in combination with carbon black is preferred as the coloring fillers.
- a preferred composition for a pencil lead comprises: 15 to 25% by weight of binder
- a pencil lead has:
- An example formulation 1 for a pencil lead comprises: polystyrene (PS) 21% by weight
- Palm oil 1 0% by weight
- An exemplary formulation 2 for a pencil lead comprises: Styrene-Acylnitrile (SAN) 15% by weight.
- a preferred composition for a crayon lead comprises: 15 to 25% by weight of binder
- a colored pencil lead has: 15 to 25% by weight polystyrene (PS)
- the mine according to the invention is produced in particular by carrying out the following steps:
- the mine cross section can take on any shape
