Abstract
The invention relates to a color change bar, which consists of a bent plastic outer tube and a glass capillary tube encapsulated inside the plastic outer tube, and is characterized in that sodium nitrite and ferric trichloride are encapsulated in the glass capillary tube, and potassium rhodanide, citric acid, EDTA (ethylene diamine tetraacetic acid), methylene green and tap water are encapsulated between the plastic outer tube and the glass capillary tube. When the bent plastic outer tube is used, the glass capillary tube fractures, and at the moment, raw material ingredients are mixed, and color change reaction is generated. The color change bar provided by the invention has the advantages that the structure is simple, the manufacture cost is low, and in addition, the environment is protected, and certain color change bars can realize the color change for many times. The color change bar belongs to an ideal toy for children.
Description
Technical field
The present invention relates to toy, specifically a kind of variable color rod.
Background technology
At present, have various glo-sticks on market, but variable color rod being very rare, can there is the variable color rod of twice variation and not report in color.And in glo-stick, normally some organic macromolecules are used as fluorescent material, they are conventionally poisonous, and it is more difficult that fluorescent material is processed, easily to environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of environment-friendly type variable color simple in structure, that cost is low excellent.
A kind of variable color rod provided by the invention, is comprised of flexible plastic outer tube and the capillary glass tube that is encapsulated in plastic outer tube the inside; It is characterized in that being packaged with in capillary glass tube natrium nitrosum and ferric trichloride; Between plastic outer tube and capillary glass tube, be packaged with potassium rhodanide, citric acid, EDTA, methylene green and running water; Their percentage by weight is:
Preparation process is as follows: first pack according to the above ratio natrium nitrosum and ferric trichloride into capillary glass tube, sealing is placed in the plastic outer tube of an end closure, then, other surplus stock is also added in plastic outer tube according to the above ratio, and sealing, makes variable color rod.Bend plastics outer tube during use, breaks capillary glass tube, and at this moment raw material components mixes, and metachromasia occurs.

Variable color provided by the invention rod compared with prior art, not only simple in structure, cost is low, and environmental protection, the repeatedly variable color having.It is a kind of comparatively ideal toy for children.
The specific embodiment
Embodiment 1
A kind of variable color rod, is comprised of flexible plastic outer tube and the capillary glass tube that is contained in plastic outer tube the inside; Preparation process is as follows: the capillary glass tube that is 10cm in internal diameter 1.45mm, external diameter 1.6mm, length dress natrium nitrosum 0.003g and ferric trichloride 0.10g, and sealing, and to be packed into diameter be in 9mm, the length plastic outer tube that is 20cm; Between plastic outer tube and capillary glass tube, pack potassium rhodanide 0.20g, citric acid 1.92g, EDTA 0.0005g and running water 10mL into, sealing, makes variable color rod.This variable color rod is colourless, and bend plastics outer tube during use, breaks capillary glass tube, and metachromasia occurs, and variable color rod becomes redness (potassium rhodanide and ferric trichloride reaction solution under acid condition takes on a red color) from colourless, and redness can not taken off.
Embodiment 2
A kind of variable color rod, is comprised of flexible plastic outer tube and the capillary glass tube that is contained in plastic outer tube the inside; Preparation process is as follows: the capillary glass tube that is 10cm in internal diameter 2.52mm, external diameter 2.7mm, length dress natrium nitrosum 0.50g, and sealing, and to be packed into diameter be in 11mm, the length plastic outer tube that is 20cm; Between plastic outer tube and capillary glass tube, pack potassium rhodanide 3.5g, citric acid 1.92g, EDTA 0.0006g and running water 10mL into, sealing, makes variable color rod.This variable color rod is colourless, bend plastics outer tube during use, capillary glass tube is broken, there is metachromasia, variable color rod is from the colourless redness that becomes, and after spending 2-3 hours, variable color rod is become colorless by redness again, and (potassium rhodanide and natrium nitrosum reaction solution under acid condition takes on a red color, As time goes on this redness is unstable takes off gradually, and last solution takes off again for colourless).
Embodiment 3
A kind of variable color rod, is comprised of flexible plastic outer tube and the capillary glass tube that is contained in plastic outer tube the inside; Preparation process is as follows: in internal diameter 1.1mm, external diameter 1.3mm, length, be 10cm capillary glass tube dress natrium nitrosum 0.002g and ferric trichloride 0.09g, and sealing, and to be packed into diameter be in 9mm, the length plastic outer tube that is 20cm; Between plastic outer tube and capillary glass tube, pack potassium rhodanide 0.19g, citric acid 1.93g, methylene green 0.02g, EDTA 0.0005g and running water 10mL into, sealing, makes variable color rod.This variable color rod is green, bend plastics outer tube during use, capillary glass tube is broken, there is metachromasia, variable color rod becomes black (potassium rhodanide and ferric trichloride reaction solution under acid condition takes on a red color, and the composite rear solution of green that the redness presenting and methylene green present is black) from green.
Embodiment 4
A kind of variable color rod, is comprised of flexible plastic outer tube and the capillary glass tube that is contained in plastic outer tube the inside; Preparation process is as follows: the capillary glass tube that is 10cm in internal diameter 2.7mm, external diameter 3.0mm, length dress natrium nitrosum 0.55g, and sealing, and to be packed into diameter be in 11mm, the length plastic outer tube that is 20cm; Between plastic outer tube and capillary glass tube, pack potassium rhodanide 3.85g, citric acid 1.93g, methylene green 0.0043g, EDTA 0.0007g and running water 10mL into, sealing, makes variable color rod.This variable color rod is green, bend plastics outer tube during use, capillary glass tube is broken, there is metachromasia, variable color rod becomes black from green, and after spending 2-3 hours, variable color rod becomes green from black again, and (potassium rhodanide and natrium nitrosum reaction solution under acid condition takes on a red color, As time goes on this redness is unstable takes off gradually, and last solution takes off again for colourless; The composite rear solution of green that the redness that in solution, reaction presents and methylene green present is black; After redness is taken off, it is green that solution recovers again).
