從表三中可看,根據本發明之複合材料的發熱效率遠優於對照例,係因為本發明預先將該碳材料與該第一乙烯基矽油均勻混合成該碳材料分散液,使該碳材料於該矽膠混合物中可以均勻分散,而可以使該微波發熱複合材料於短時間內達成均勻發熱,而對照例4與對照例5則是因為奈米碳管粉末無法均勻的分散,而導致冒煙或起火。且若分散不均,會造成表面粗糙,影響終端產品的外觀與觸感。由於該碳材料的分散性難有標準可供量測,故在此採用電阻表達,若電阻較低則表示該碳材料的分散性較佳,但需特別說明的是,於同濃度下分散性越好,則電阻越低,但若兩者之濃度不同,電阻越低,並非代表分散性越好。It can be seen from Table 3 that the heat-generating efficiency of the composite material according to the present invention is much better than that of the comparative example because the carbon material is uniformly mixed with the first vinyl-cement oil into the carbon material dispersion in advance, so that the carbon The material can be uniformly dispersed in the silicone mixture, and the microwave heating composite can achieve uniform heating in a short time, while the comparative example 4 and the comparative example 5 are because the carbon nanotube powder cannot be uniformly dispersed, resulting in Smoke or fire. If the dispersion is uneven, the surface will be rough and affect the appearance and touch of the end product. Since the dispersibility of the carbon material is difficult to measure by standard, the resistance is expressed here. If the resistance is low, the dispersibility of the carbon material is better, but it is particularly noted that the dispersibility is the same concentration. The better, the lower the resistance, but if the concentrations of the two are different, the lower the resistance, the better the dispersion.
表四呈現實驗例和各對照例的電阻量測結果,其中,實驗例1因碳材料的分散性佳,因此電阻值係低於對照例1、2和3;至於對照例4與5,由前述微波加熱實驗可知,其碳材料的分散性不佳,故電阻值較低的貢獻係來自於較高的碳濃度。Table 4 shows the resistance measurement results of the experimental examples and the respective comparative examples, wherein the experimental example 1 has a good dispersibility of the carbon material, so the resistance value is lower than that of the comparative examples 1, 2 and 3; and as for the comparative examples 4 and 5, The microwave heating experiment described above shows that the dispersibility of the carbon material is not good, so the contribution of the lower resistance value is derived from the higher carbon concentration.
此外,矽膠的生物相容性好,當其可發熱時,更可有效達成仿生之效果,故所生產之終端產品可用於情趣用品、機器人仿生肌肉與皮膚、人工義肢等等,若用於情趣用品,因其可用微波爐加熱,所以等待時間短,使用者體驗佳,並可配合VR、AR、MR技術,或加裝其他裝置,例如震動元件等,以達到最佳的仿生與虛擬實境效果。In addition, silicone has good biocompatibility, and when it can be heated, it can effectively achieve the effect of bionics. Therefore, the end products produced can be used for sex toys, robotic bionic muscles and skin, artificial prostheses, etc. Supplies, because they can be heated in a microwave oven, so the waiting time is short, the user experience is good, and can be combined with VR, AR, MR technology, or other devices, such as vibration components, to achieve the best bionic and virtual reality effects .
且於應用時,該微波發熱複合材料的外部可以塗覆其他物質,以進行染色等動作。以下係製備其它實驗例來說明,實驗例2和實驗例1相同,外部未上色,而實驗例3為將實驗例1的外部進行上色,上色塗層的重量約為10.137g。針對實驗例2和實驗例3進行微波加熱測試,以1000W的微波火力,每5秒量測溫度,結果如表五;此外,還進一步針對實驗例2和實驗例3,測試其持溫能力,測試方法為停止施以微波,並將複合材料靜置於室溫環境,每5秒量測溫度,結果如表六。 表五、微波火力1000W,微波時間與溫度對照表 <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> 微波時間(Sec) </td><td> 實驗例2 </td><td> 實驗例3 </td></tr><tr><td> 0 </td><td> 27.6 </td><td> 27 </td></tr><tr><td> 5 </td><td> 29.7 </td><td> 28.8 </td></tr><tr><td> 10 </td><td> 43.8 </td><td> 43.5 </td></tr><tr><td> 15 </td><td> 50 </td><td> 58 </td></tr><tr><td> 20 </td><td> 68 </td><td> 70 </td></tr><tr><td> 25 </td><td> 83 </td><td> 80 </td></tr></TBODY></TABLE>表六、微波後靜置於室溫之時間與溫度對照表 <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> 靜置時間(Min) </td><td> 實驗例2 </td><td> 實驗例3 </td></tr><tr><td> 5 </td><td> 42.5 </td><td> 65 </td></tr><tr><td> 10 </td><td> 41 </td><td> 57 </td></tr><tr><td> 15 </td><td> 40 </td><td> 53 </td></tr><tr><td> 20 </td><td> 38.2 </td><td> 48 </td></tr><tr><td> 25 </td><td> 37.7 </td><td> 44 </td></tr><tr><td> 30 </td><td> 36.9 </td><td> 42 </td></tr><tr><td> 40 </td><td> 34.7 </td><td> 38 </td></tr><tr><td> 50 </td><td> 33 </td><td> 35 </td></tr><tr><td> 60 </td><td> 32.1 </td><td> 33 </td></tr></TBODY></TABLE>Moreover, when applied, the exterior of the microwave heat-generating composite material may be coated with other substances for performing dyeing and the like. In the following, other experimental examples were prepared to illustrate that Experimental Example 2 was the same as Experimental Example 1, and the exterior was not colored, and Experimental Example 3 was that the exterior of Experimental Example 1 was colored, and the weight of the colored coating layer was about 10.137 g. The microwave heating test was carried out for Experimental Example 2 and Experimental Example 3, and the temperature was measured every 5 seconds with a microwave power of 1000 W. The results are shown in Table 5; in addition, the temperature holding ability was further tested for Experimental Example 2 and Experimental Example 3, The test method is to stop applying microwave, and the composite material is placed in a room temperature environment, and the temperature is measured every 5 seconds.

由上表可知,縱使有塗層的狀況下,實驗例3的升溫速度和發熱效率仍可維持一定能例,且兩者均有不錯的持溫效果。因此,可以配合各種需求,調整雙層結構之配色與溫控,以滿足所需。且除上述所說,亦可以應用在暖暖包、防凍手套、防凍頭套、防凍耳罩、防凍面罩、防凍安全帽內襯、面膜加熱材料及醫療熱敷材料等。As can be seen from the above table, even in the case of a coating, the temperature rising rate and the heat generation efficiency of Experimental Example 3 can be maintained as a certain example, and both have a good temperature holding effect. Therefore, it is possible to adjust the color matching and temperature control of the double-layer structure to meet various needs. In addition to the above, it can also be applied to warm packs, antifreeze gloves, antifreeze hoods, antifreeze earmuffs, antifreeze masks, antifreeze helmet linings, mask heating materials and medical hot compress materials.
