Embodiment 1

[0037] Step 1: Take 1000g of the raw silica gel with a hardness of 40 degrees and put it in the rubber mixing machine for mixing. At this time, the hardness of the silica gel in the rubber mixing machine is still 40 degrees.

[0038] Step 2: During the process of mixing silica gel, add 20g of vulcanizing agent, and the vulcanizing agent is bis-2.5 vulcanizing agent.

[0039] Step 3: Add 8g of color-changing powder during the process of mixing silica gel. The proportion of color-changing powder is 27.2% polyoxymethylene melamine, 6.8% styrene maleic anhydride polymer, and 15.5 cetyl alcohol. %, stearyl alcohol 37%, behenol 9.5%, orange dichlorofluorescein 2.8%, red dichlorofluorescein 1.2%.

[0040] Step 4: Add 10g of pink color glue during the process of mixing silica gel.

[0041] Step 5: In the rubber mixing process, adding an internal mold release agent, the internal mold release agent does not produce a physical-mechanical chemical reaction with the color change powder and the col...

Embodiment 2

[0045] Step 1: Take 500g of raw silica gel with a hardness of 30 degrees, take 500g of raw silica gel with a hardness of 50 degrees, and put them in a rubber mixing machine for mixing. The hardness of the silica gel after mixing is 40 degrees.

[0046] Step 2: Add 20g of vulcanizing agent during the process of mixing silica gel.

[0047] Step 3: Add 9g of color-changing powder during the process of mixing silica gel. The proportion of color-changing powder is 19.3% of polyoxymethylene melamine, 7.8% of styrene maleic anhydride polymer, and 17.0 of cetyl alcohol. %, stearyl alcohol 39.5%, behenol 10.8%, orange dichlorofluorescein 3.7%, red dichlorofluorescein 1.9%.

[0048] Step 4: Add 9g of yellow glue during the process of mixing silica gel.

[0049] Step five, during the rubber mixing process, add internal release agent.

[0050] Step 6: Divide the color-changing silica gel after mixing into strips, weigh them and put them into the mold of the silica gel and perform injection molding...

Embodiment 3

[0053] Step 1: Take 1000g of the raw silica gel with a hardness of 40 degrees and put it in a rubber mixing machine for mixing. The hardness of the silica gel after mixing is 40 degrees.

[0054] Step 2: During the process of mixing silica gel, add 18 g of vulcanizing agent and put it in the mixing machine for mixing.

[0055] Step 3. Add 9g of color-changing powder during the process of mixing silica gel. The proportion of color-changing powder is 23.4% polyoxymethylene melamine, 7.6% styrene maleic anhydride polymer, and 16.1 cetyl alcohol. %, stearyl alcohol 38.2%, behenol 9.4%, orange dichlorofluorescein 3.6%, red dichlorofluorescein 1.7%.

[0056] Step 4: Add 9g of yellow color gum during the silica gel mixing process.

[0057] Step five, during the rubber mixing process, add internal release agent.

[0058] Step 6: Divide the color-changing silica gel after mixing into strips, weigh them and put them into the mold of the silica gel and perform injection molding, and keep the inje...

Abstract

The invention provides preparation technology of allochroic silica gel and allochroic silica gel utensils. The allochroic silica gel comprises following raw materials: silica gel raw gel with a hardness of 40 DEG, coloring agents, and an allochroic powder; the allochroic powder comprises polyoxymethylene melamine, styrene maleic anhydride polymer, a surface active thickening agent, and dichloro fluorescein; and the ratio of the coloring agents to the allochroic powder is controlled to be 1:0.5-1. The allochroic silicagel is capable of displaying the color of doped coloring agents of different colors at different temperatures through the fluorescence effect of the allochroic powder with heat sensitivity; especially, color change can be realized in a very short time period at critical temperature values.

Description

Technical field [0001] The invention relates to the technical field of use silica gel, in particular to a preparation process of color-changing silica gel and a color-changing silica gel appliance. Background technique [0002] Silicone appliances have infiltrated people's daily life due to their high temperature resistance, low temperature resistance, radiation protection, easy cleaning, hard to damage, soft and comfortable, and diverse colors. [0003] Take the silicone cup as an example. The existing silicone cup is a water cup made of food-grade silicone. It is characterized by safety, non-toxicity, drop resistance, non-slip, and moderate hardness. It is loved by young people. Adding just boiling water will be very hot, and the user does not know when the water will cool down. In order to solve this problem, it has appeared that by adding thermochromic materials to the silica gel, the silica gel has the characteristics of changing the color with the change of temperature.
