Embodiment 1

[0022] A multifunctional colored pencil lead, prepared from the following raw materials in mass percentage: 10% clay with a water content of 40%, 40% fine talc powder of 1250 mesh, 20% calcium stearate, 10% Tween, permanent Violet 4%, sodium carboxymethylcellulose 6% and No. 90 microfine wax 10%.

Embodiment 2

[0024] A method for preparing a multifunctional colored pencil lead, comprising the steps of:

[0025] (A) Washed clay with a water content of 40%, 1250 mesh fine talcum powder, stearate, magnesium stearate, green lotus, sodium carboxymethylcellulose and No. 90 heated to 180° The micro-fine wax is mixed according to the mass ratio of 5:20:10:5:2:3:5 and then put into the mixer. Set the speed of the mixer to 1500r / min, stir for 6 hours, and make a core material with a water content of 6%.

[0026] (B) Put the stirred core material into a three-roll mill and grind it to make a 180-mesh core material; after sealing and storing the ground core material for 48 hours, it is divided into 4 times and added with a pressure of 400 tons. Squeeze in the core pressing machine, and be pressed into the multifunctional colored pencil lead pre-finished product that diameter is 2.2mm, and length is 22cm; The lead core that described pressing is put into drying core furnace, under the condition ...

Embodiment 3

[0028] A method for preparing a multifunctional colored pencil lead, comprising the steps of:

[0029] (A) Washed clay with a water content of 40%, 1250 mesh fine talcum powder, stearate, magnesium stearate, green lotus, sodium carboxymethylcellulose and No. 90 heated to 180° The micro-fine wax is mixed according to the mass ratio of 5:20:10:5:2:3:5 and put into the mixer. Set the speed of the mixer to 2000r / min and stir for 6 hours to make a core with a water content of 6% to 8%. material;

[0030] (B) Put the stirred core material into a three-roll mill and grind it to make a 200-mesh core material; after sealing and storing the ground core material for 48 hours, it is divided into 4 times and added with a pressure of 500 tons. Squeeze in the core pressing machine, and be pressed into the multifunctional colored pencil lead pre-finished product that diameter is 8.0mm, and length is 22cm; The lead core that described pressing is packed into core drying oven, under the condit...

Abstract

The invention discloses a multifunctional colored pencil core. The multifunctional colored pencil core is prepared from the following raw materials in percentage by weight: 10% of clay, 40% of fine talcum powder, 20% of stearate, 10% of surfactant, 4% of pigment, 6% of sodium carboxymethylcellulose and 10% of micronized refined wax. A preparation method of the multifunctional colored pencil core comprises the following steps: stirring, grinding, storing, pressing, core drying, and end cropping, thereby obtaining the multifunctional colored pencil core. The multifunctional colored pencil core prepared by the preparation method has the advantages that writing on dry materials and wet materials can be realized, if the pencil core is applied to writing on dry paper, the effect of graphite is achieved, and if the pencil core is applied to writing on the wet materials, the effect of a water-soluble colored pencil core is achieved, and therefore, the effect of utilizing one pencil for multiple purposes is achieved.

Description

technical field [0001] The invention relates to a pencil lead and a preparation method thereof, in particular to a multifunctional colored pencil lead and a preparation method thereof. Background technique [0002] At present, the existing lead cores are only divided into graphite lead cores and water-soluble colored lead cores. Graphite lead cores can only be written on dry items, and water-soluble colored lead cores can only be written on wet items. The application range is relatively narrow. Because sometimes it is necessary to write alternately on dry and wet objects, graphite lead and water-soluble colored lead cannot be used, and it is very troublesome to use alternately, so it is necessary to invent a pencil lead that can write on dry and wet objects . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional colored pencil lead. The advantage of the multifunctional colored pencil lead is that the...
