Example Embodiment

[0028] Example 1:

[0029] See figure 1 , The method for preparing the high-performance thermochromic material provided by the embodiment of the present invention includes the following steps:

[0030] 1) Preparation of raw materials: According to weight percentage, weigh the following raw material components:

[0031] Polypropylene resin 95-99.8, thermochromic powder 0.1-4.9, white oil 0.1-0.5. Adjust the weight percentage of the thermochromic powder according to the color depth; the thermochromic powder is a powdered reversible organic thermochromic material purchased from the market or prepared according to conventional methods, such as fluorane compounds as the color-developing agent The thermochromic materials, etc. According to the application temperature of the general straw (that is, the temperature at which liquid may be absorbed in daily life), the color change temperature of the thermochromic powder is set to: 31℃, 38℃, 43℃, 45℃, and the thermochromic powder can be adjus...

[0046] Example 2:

[0047] The method for preparing the high-performance thermochromic material provided by the present invention includes the following steps:

[0048] 1) Preparation of raw materials: According to weight percentage, weigh the following raw material components:

[0049] Polypropylene resin 95, thermochromic powder 4.9, white oil 0.1.

[0050] 2) Mixing of components:

[0051] 2.1) Firstly, the above components are prepared into 100-300 mesh powder, and dried;

[0052] 2.2) Weigh 1 / 3 of the total polypropylene resin, add all the thermochromic powder, stir and mix; the thermochromic powder and polypropylene resin particles should be fully mixed evenly;

[0053] 2.3) Then gradually add the remaining polypropylene resin and white oil and stir and mix until the addition is complete, so that the powder components are uniformly mixed to form a polypropylene resin modified mixture;

[0054] 3) Put the polypropylene resin modified mixture under low temperature conditions, vacuum, a...

Abstract

The invention provides a preparation method of a high-performance thermochromic material, which is characterized by comprising the following steps: 1) preparation of raw materials: weighing 95-99.8 wt% of polypropylene resin, 0.1-4.9 wt% of thermochromic powder and 0.1-0.5 wt% of white oil; 2) component mixing: mixing the components at low temperature in a vacuum to form a polypropylene resin modified mixture; and 3) standing the modified mixture at low temperature to form a high-performance thermochromic material. The method for preparing suckers from the thermochromic material comprises the following steps: 4) preparing a sucker extrusion host machine and a die head matched with the host machine; 5) sending the modified mixture into the extrusion host machine to obtain the continuous linear sucker; and 6) cutting the prepared continuous linear sucker into suction tube sections, thereby obtaining the thermochromic suckers. The preparation method provided by the invention is scientific and reasonable, and has the advantages of high production efficiency, favorable product performance and low cost.

Description

technical field [0001] The invention relates to the production of a plastic food utensil, in particular to a high-performance temperature-sensitive color-changing material and a preparation method of a straw Background technique [0002] When a baby uses a straw, in order to prevent the temperature of the prepared food from being too high and scalding the child, adults often try it with a straw before feeding, which is not hygienic. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a method for preparing a high-performance thermochromic material to replace various existing plastics that cannot change color; [0004] The object of the present invention is also to provide a method for preparing straws using the above-mentioned high-performance thermochromic material, so as to improve the manufacturing efficiency of the straws, and to manufacture various straws that meet the re...
