Problems solved by technology

But relatively speaking, its color is single, the cost is high, the requirements for processing conditions and equipment are high, light resistance and temperature resistance are poor, and the long-term use temperature is usually lower than 80°C, and it cannot be mixed with other titanium dioxide, carbon black, barium sulfate, etc. Inorganic toner, certain phosphorus-containing chemical substances, and plasticizers are used together, otherwise it will cause problems such as residual background color or discoloration failure, which greatly limits the application range of thermochromic pigments

Embodiment 1

[0036] Prepare materials according to the following components and parts by weight:

[0037]

[0038] Among them, the thermoplastic resin is PP;

[0039] The thermoplastic elastomer is EPR;

[0040] The flake pigment is bismuth oxide coated pearlescent pigment, with a particle size of 20-200 μm;

[0041] The processing aid is Ciba Specialty Antioxidant B9000.3, the lubricant is zinc stearate 0.5, and the light stabilizer is Ciba Specialty UVP (hydroxybenzotriazole) and 770 (hindered amine) 0.1 each.

[0042] To accentuate the difference in color, some red organic dye is added.

Embodiment 2

[0044] Prepare materials according to the following components and parts by weight:

[0045]

[0046]

[0047] Wherein, thermoplastic resin is PVC;

[0048] The thermoplastic elastomer is EPR;

[0049] The flake pigments are mica-based pearlescent pigments with a particle size of 200-500 μm;

[0050] The processing aid is Ciba Specialty Chemical Antioxidant B9000.3, the lubricant is magnesium stearate 1.0, and the light stabilizer is Ciba Specialty Chemical UVP, 0.1 each of 770. To accentuate the difference in color, some red organic dye is added.

Embodiment 3

[0052] The component ingredients are the same as in Example 2, only on the basis of Example 2, the flake pigments are changed from mica-based pearlescent pigments to flake aluminum powder pigments with a particle size of 100 μm.

Abstract

The invention relates to a resin composition for temperature control indication. The resin composition comprises the following ingredients, by weight: 10-90 parts of thermoplastic resin, 10-90 parts of thermoplastic elastomer, 0-5.0 parts of compatilizer, 0.1-5.0 parts of sheet pigment and 0.1-2.0 parts if processing auxiliary agent. Compared with a prior art, the thermoplastic resin composition prepared by the invention can be used for temperature control and alarm indication; compared with traditional temperature display methods of electron microprobe, infrared radiation and mercury thermometer, the preparation method has advantages of simpleness, effectiveness, sensitive reaction and low cost, can be widely applied to temperature control alarm of large and small machinery equipment and apparatuses and has huge market prospect in fields of machinery and material processing, chemical engineering, electronic apparatus and monitor on various experiment processes, etc.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a resin composition with a high linear thermal expansion coefficient, and more specifically to a resin composition that can be used for temperature control indication. Background technique [0002] Temperature display and monitoring is an indispensable link in a wide range of fields such as mechanical processing, electronic equipment, chemical engineering, experimental process control, household appliances, and automobiles. It is one of the necessary conditions to ensure the smooth progress of production, quality, and safety. The traditional methods used for temperature display and monitoring are mainly electronic probes, infrared radiation sensors, mercury thermometers, thermocouples, etc. These temperature display and monitoring methods can often accurately display the actual temperature with high accuracy, but the installation of these devices also brings complicated...
