Problems solved by technology

[0004] However, the usable temperature range of this microcapsule film is narrow (20-35°C), which greatly limits the application. Products in many industries and fields cannot be tested with this type of film. Moreover, its mechanical properties are poor, so the usability Not good; in addition, this kind of film uses capsules to release dyes under pressure to measure pressure, which has high cost and is prone to rupture during processing. Therefore, the processing conditions are very demanding and the productivity is poor, so it is difficult to meet the increasing market demand.

preparation example Construction

[0067] The present invention also provides a method for preparing the pressure-sensitive material described in the above technical solution, including:

[0068] The pressure-sensitive compound, modifying agent, antioxidant and heat stabilizer are mixed at 25-80°C to obtain the pressure-sensitive material.

[0069] Wherein, the pressure-sensitive compound is consistent with that described in the above technical solution, and will not be repeated here.

[0070] The present invention has no special limitation on the mixing order of the raw materials. In some embodiments, all the raw materials can be mixed together; Stabilizer mix. The present invention has no special limitation on the mixing method and equipment, as long as the raw materials can be mixed evenly, for example, a high-speed stirrer well known to those skilled in the art can be used for mixing.

[0071] In the present invention, the mixing temperature is preferably 25-80° C.; the mixing time is preferably 3-6 minut...

Embodiment 1

[0085] 100g formula (I) pressure sensitive compound (R 1 For formula I-2, R 2 I-3), 1g of dimethylsiloxane, 0.1g of 2,2'-methylenebis-(4-methyl-6-tert-butylphenol) and 1g of dibutyltin dilaurate are put into the mixing equipment in turn , mixed at 25° C. for 0.5 min, then at 40° C. for 1 min, and finally at 50° C. for 1 min. After mixing evenly, take it out to obtain a pressure-sensitive material.

[0086] The pressure-sensitive material is mixed with the binder to obtain a coated pressure-sensitive material, which is then coated on the surface of the substrate film at a coating speed of 3 min / m, and a pressure-sensitive film is obtained after coating.

Embodiment 2

Abstract

The invention provides a pressure-sensitive compound, a pressure-sensitive material, a preparation method thereof and a pressure-sensitive film. The pressure-sensitive compound provided by the invention can form a compound of another structure after being pressed. Before and after the compound is pressed, two compounds are different in color, so that a color difference is formed. The larger the pressure, the larger the color difference. Based on the color difference, the size of the pressure can be judged. The pressure-sensitive compound is large in applicable temperature range and can be applied to the pressure sensing tests of various electronic consumer products, batteries and the like. The compound is high in mechanical performance, convenient to use and good in mechanical sensitivity.The compound can be applied to the pressure measurement of products in the low-pressure industry, and the application field of pressure measurement materials is expanded.

Description

technical field [0001] The invention relates to the technical field of sensing materials, in particular to a pressure-sensitive compound, a pressure-sensitive material, a preparation method thereof, and a pressure-sensitive film. Background technique [0002] Pressure-measuring film or pressure-sensitive film is a film used to test pressure and pressure distribution. For example, for color-changing pressure-measuring film, when different pressures act on this film, the film will show different shades of color, which can be used to reflect Pressure effect and pressure size distribution. This type of product is used to test the pressure and pressure distribution in industrial production, and is also used to test the flatness and parallelism of the calibration work surface (for example, if the work is flat, the pressure will be uniform, the color of the film will be uniform, if it is not flat, then If the pressure is uneven, the color development in different areas of the film...
