Description

Technical Field

[0001] The invention relates to a pastel stick and a production and processing method thereof. Background Art

[0002] Pastel sticks are solid powder products that can be attached to other objects when used. They have a variety of uses. They are named because they often contain coloring ingredients (pigments) and are processed into sticks. Pastel sticks can be directly cut into chalks commonly used in teaching, and can also be used as raw materials for the production of watercolor paints and colored clay. They can also be used as heat shrink sheets, hair, nails, etc. in the beauty and hairdressing industries. At present, such products on the market are not satisfactory in terms of quality and performance due to defects in raw material formula and processing technology. For example, the product powder is relatively rough, easy to fall off, low strength, easy to break, weak adhesion when writing, not smooth enough, and produces a lot of dust. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a pastel stick with excellent quality and performance and a production and processing method thereof, so as to overcome the shortcomings of the existing products of this type as described in the background technology.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a pastel stick, which comprises the following components by weight percentage: 82% to 88% of calcium carbonate, 3% to 7% of pigment, 6% to 10% of clay, and 1% to 3% of adhesive.

[0005] Furthermore, the adhesive is at least one of glycerol, polyethylene glycol, and sodium alginate.

[0006] A method for producing and processing the above-mentioned pastel sticks, the production and processing steps are:

[0007] (1) Pour 82% to 88% of calcium carbonate, 3% to 7% of pigment, 6% to 10% of clay, and 1% to 3% of adhesive into a container by weighing, add an appropriate amount of water, and stir mechanically until all the materials are evenly mixed to form a well-bonded powder;

[0008] (2) Put the bonded powder into a grinder for grinding to make the powder more uniform, finer and smoother;

[0009] (3) feeding the ground powder into a pressure extrusion molding machine, and extruding the powder into a predetermined mold under high pressure by the pressure extrusion molding machine;

[0010] (4) Place the extruded product into a die-cutting machine and cut it into the required length;

[0011] (5) placing the cut products on a drying rack for natural drying, or placing them in a drying device for rapid drying, thereby obtaining finished pastel sticks.

[0012] (6) The finished pastel sticks are packaged manually or mechanically, and the packaging material is a plastic container, a blister card or a sponge bag.

[0013] The beneficial effects of the present invention are as follows: the pastel stick product of the present invention has uniform and fine powder quality, a smooth surface that is not easy to get stuck on the hands, high strength and not easy to break. When used as chalk, writing is smooth and has good adhesion (i.e., clear handwriting), and little dust is dropped and the dust is not easy to fly away. It is durable, environmentally friendly and beneficial to health; when used as a raw material for the production of watercolor pigments and color mud, and as a coloring material for heat shrink sheets, hair and nails in the beauty and hairdressing industry, it has good performance (fine powder quality, uniform color and good adhesion). DETAILED DESCRIPTION

[0014] The present invention is further described below by means of several embodiments.

[0015] Example 1

[0016] A pastel stick comprises the following components by weight percentage: 82% calcium carbonate, 5% pigment, 10% clay, and 3% adhesive. The adhesive is glycerol. Glycerol is used as the adhesive. Since glycerol is hygroscopic, it can prevent the pastel stick from cracking due to drying during storage and use, and helps to improve the writing fluency of the pastel stick when used as chalk.

[0017] The method for producing and processing the above-mentioned pastel sticks comprises the following steps:

[0018] (1) Pour 82% of calcium carbonate, 5% of pigment, 10% of clay, and 3% of adhesive by weight into a container by weighing, add an appropriate amount of water, and stir mechanically until all the materials are evenly mixed to form a well-bonded powder;
