Description

Crayons using waste food as paint

This work is about a kind of crayon, especially a kind of crayon that uses waste food as pigment.

In the process of children's growth, in order to stimulate children's creativity and imagination, parents or kindergarten teachers usually achieve this goal by drawing, and drawing can be created using watercolor pens, colored pens or crayons.

Because watercolor needs to use various kinds of pigments for color matching, it is more difficult to operate compared to children's painting; and the color pen itself uses ink of various colors, and it is easy to change the color due to insufficient ink when painting a large area during the painting process. Faint or unpaintable. Therefore, crayons are more suitable painting tools, and compared with watercolor pens or colored pens, they are more convenient to use and have the advantage of being cheap.

In addition, watercolor pens must be cleaned after use, and the subsequent finishing steps are cumbersome, and the cleaning liquid may be directly discharged into the gutter without treatment, which may lead to environmental pollution. Generally, if there is no ink after use, few people will buy additional color pens. Ink is added, but directly discarded together with the pen body and then buys a new set of colored pens, resulting in a waste of resources; and crayons do not need a carrier to be used, they are consumed during painting, and do not need to be cleaned, so they are more suitable painting tools.

In recent years, due to the gradual improvement of people's safety awareness, attention has been paid to the hygiene and toxicity of infants or children's products. Although crayons have the advantages mentioned above, their ingredients basically contain more chemical pigments, which still have Toxicity; therefore, it is necessary to find non-toxic natural pigments to replace traditional chemical pigments.

In view of the above-mentioned problems of the prior art, the purpose of this creation is to provide a crayon using waste food materials as pigments.

Crayons are drawing materials obtained by mixing paraffin wax or wood wax with pigments, melting them, and then solidifying them. Called crayons or pastels. Generally speaking, crayons are made by the following method: after the oil and wax are put into a container, heated, melted and uniformly mixed, various pigments are added to the container, and the pigments and a small amount of wax are mixed thoroughly and then mixed. After mixing to form a homogeneous mixture, the homogeneous mixture is then put into a mold to cool and solidify slowly, which is the finished crayon.

Among them, in the pigment part, in order to reduce the toxicity of traditional chemical pigments, waste food materials are used as raw materials, so as to prevent children or young children from using crayons to draw food without washing their hands or directly into the mouth, resulting in the consumption of toxic chemical pigments.

The sources of discarded food materials are the wastes left over from the processing of natural food materials such as vegetables or fruits before cooking, or vegetables or fruits that cannot be eaten due to the expiration of the shelf life.

In recent years, Taiwan has recycled an average of about 540,000 tons of cooked food waste and 230,000 tons of raw food waste every year. In addition, 1.44 million tons of food waste is mixed with general garbage and all burned. In addition to causing food waste, the recycling pipeline is still insufficient. ; Furthermore, some vegetables or fruits face the problem of being destroyed due to overproduction, improper transportation or storage, and ingredients that do not meet food specifications.

However, the natural pigments contained in many vegetables or fruits can be used as pigments and are basically non-toxic. Even if children accidentally eat them, they will not be poisoned. It can further reduce the waste of natural ingredients such as vegetables or fruits. , reduce the disposal cost of waste food materials. Therefore, the creator of this creation uses waste food such as vegetables or fruits as pigments to make crayons to achieve the above advantages.

The crayon, which uses waste food as pigment, is integrally formed with: a pen body; and pen ends located at both ends of the pen body, the pen body is used for the user to hold, and the two sides are Both pen ends can be used to allow users to draw patterns on paper.

Wherein, the crayon is made of waste food materials as a pigment, supplemented by a wax composition, and the preparation steps are as follows:

Step S1: drying the discarded vegetables or fruits to remove moisture.

Step S2: Grind the vegetables or fruits discarded after drying into powder.

Step S3: adding the wax composition and/or titanium dioxide to the discarded vegetables or fruits ground into powder and heating and stirring to form a uniform mixture.

Step S4: Pour the homogeneous mixture into the crayon mold, and after cooling and solidifying, the finished crayon is obtained.

In the above-mentioned step S1, the discarded vegetables or fruits can be onions, turmeric, carrots, wood blue, beets, peppers, etc., and different discarded vegetables or fruits can be selected according to the color of the crayon to be made to remove moisture to reduce The effect of moisture on the pigments contained in such discarded vegetables or fruits.

In the above-mentioned step S2, the vegetables or fruits discarded after drying have a grinding particle size of about 20-50 μm, so that the wax composition can be uniformly mixed without caking when the wax composition is subsequently added.

In the above step S3, the wax composition is composed of soybean wax, beeswax, candrillara wax and stearic acid, and the temperature of heating and stirring is 150-200°C.

Finally, in the above step S4, the crayon mold is cylindrical.

To sum up, crayons that use waste food materials as pigments can reduce the cost of processing waste food materials by using the waste materials left after processing natural food materials or natural food materials that are expired and inedible, thereby reducing the cost of processing waste food materials; in addition, it is made from waste materials of natural food materials Compared with the crayons using chemical raw materials, this crayon is less toxic, and children can use it with peace of mind.

Hereinafter, the crayons using waste food materials as pigments and the preparation process thereof will be described with reference to the embodiments and the accompanying drawings.
