Problems solved by technology

[0003] Although there are many ways to make it, the existing erasers are all fixed colors and cannot change with changes in the external environment (temperature and ultraviolet rays)
Its color is fixed, it cannot attract more people's love, and it is difficult to expand the market

Embodiment 1

[0035] like figure 1 As shown, the color-changing eraser disclosed in this embodiment includes an eraser body 1, and the eraser body 1 in this embodiment is entirely made of a color-changing material. The color-changing material includes thermochromic material or photochromic material. Thermochromic materials can repeatedly reverse color with the rise and fall of temperature. Taking red at 31°C as an example, the discoloration form is colorless above 31°C and red below 31°C. Photochromic materials begin to change color when exposed to ultraviolet light. In this embodiment, the temperature-sensitive color-changing material is selected from temperature-sensitive pigments, such as color-changing microcapsules.

[0036] The manufacture method of the color-changing eraser disclosed in this embodiment comprises the following steps;

[0037] Step 1, making the color-changing material: the color-changing material in this embodiment is a mixture of color-changing microcapsules, pig...

Embodiment 2

[0046] The difference between the present embodiment and the first embodiment is that in the present embodiment, part of the eraser body is made of a color-changing material. like figure 2 As shown, the eraser body 1 includes a discoloration zone 2 and a discoloration zone 3 . The color of the discoloration area 2 can change with the external environment, and the color of the non-discoloration area 3 does not change with the external environment. The non-discoloration zone 3 is made of non-discoloration material.

[0047] The manufacture method of the color-changing eraser disclosed in this embodiment comprises the following steps;

[0048] Step 1, making color-changing materials and non-color-changing materials respectively. The color-changing material in this embodiment is the same as that in Embodiment 1. I won't repeat them here.

[0049] The non-discoloration material in this embodiment is a mixture of pvc, dotp, soybean oil, barium stearate and zinc stearate. Its ...

Abstract

The invention relates to a color-changing eraser and a manufacturing method thereof, and belongs to the technical field of office supplies. The color-changing eraser comprises an eraser body, the eraser body is partially or completely made of a color-changing material, the color-changing material comprises a temperature sensing color-changing material or a light sensing color-changing material, and the color-changing material is a mixture of color-changing microcapsules, pigment powder, pvc, atbc, dotp, soybean oil, paraffin, barium stearate and zinc stearate. According to the color-changing eraser and the manufacturing method thereof, the color of the eraser can change along with changes of external environments (including the temperature and ultraviolet rays); and the magic feeling brought by the fact that the color of the eraser changes along with environmental changes can be expressed more richly, the eraser can be more popular with the public and especially be more popular with children, people can be guided to strip handwriting from substances on the surface of a written object through the physical principle but not a magic pen, and then the market is further expanded.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to a color-changing eraser and a manufacturing method thereof. Background technique [0002] Erasers are commonly used office supplies. The making mode of rubber sassafras usually has: 1, the synthetic rubber of powder or liquid state is transported to rubber factory by petroleum processing plant. If natural rubber is to be used, it arrives in solid chunks, which workers must first crush and dissolve. 2. Rubber is mixed with ground pumice powder (rubber can be made slightly thicker), iron oxide (rubber can be made pink), vegetable oil, sulfur and other substances. 3. Heating the mixture causes the sulfur to mix with the rubber to increase the strength of the rubber and make it more durable. 4. Feed the soft, still warm material into a stamping machine (squeezed into a die) to make long, thin rubber sticks. Cut the rubber stick into small pieces with a knife, wait for it ...
