全球使用過潤滑劑約有50 %~60 %最終流入環境造成污染[1]，因此，近幾年來市面上有極少數使用植物提煉的生質潤滑劑以解決此問題，包含大豆油、椰子油、橄欖油等等，但是這些都是糧食作物，若是大量地將糧食作物當作提煉生質潤滑劑的材料，必定會造成全球糧食危機，如果使用植物廢棄物提煉則能夠同時避免糧食與環境問題。本論文使用微波法以四種提煉溫度將咖啡渣提煉成咖啡渣基礎油，檢測基本性質並從四種提煉溫度中選出最佳的提煉溫度，再將最佳咖啡渣基礎油調配成三種含水量與有無鹼性添加劑咖啡渣潤滑油兩種，總共六種咖啡渣潤滑油組合，並與商用研磨切削油進行基本性質與磨潤性能的比較。主要結果說明如下: (1)提煉溫度420 ℃的咖啡渣基礎油調配成92%含水量後總酸價為最低23.1 mg KOH/g、最高的pH值4.03與提煉比26%，綜合性質與成本為四種提煉溫度中的最佳選擇。(2)本製程咖啡渣基礎油不需透過乳化添加劑即可以均勻與水混合，且不會產生油水分離的現象，可減少一般乳化劑造成生菌與臭味現象。(3) 依據業界氧化目視法與成分分析，咖啡渣潤滑油均不會對三種鋁合金造成氧化或腐蝕現象。(4)提煉咖啡渣潤滑油留下的碳化咖啡渣為生物碳，可以作為改善土壤及吸碳材料，因此本製造方法為零廢棄物的循環經濟產品。(5)咖啡渣潤滑油的總酸價值及接觸角度會隨著含水量上升而上升，pH值及黏度值會隨著含水量下降而下降。(6)在本實驗參數下，含水量92 %咖啡渣潤滑油由於具有最低接觸角，故其磨耗量與平均摩擦力低於添加鹼性添加劑之咖啡渣潤滑油與商用研磨切削油。(7)就摩擦、磨耗、抗腐蝕性能而言，420 ℃提煉溫度與92 %含水量的咖啡渣潤滑油具有取代半合成研磨切削油之潛力，並且是全球首創的咖啡渣潤滑油提煉方法。(8)基於咖啡渣潤滑油在含水量87%、92 %、 97 %的摩擦力變化，建議含水量89%94 %作為工廠加水或加油的標準..

520 3 $a Approximately 50% to 60% of lubricants used globally eventually enter the environment[1], leading to pollution. In recent years, a small number of bio-lubricants derived from plant oils, such as soybean oil, coconut oil, and olive oil, have been developed to address this issue. However, these oils are primarily food crops, and extensive use of these crops for bio-lubricant production could lead to a global food crisis. Utilizing plant waste for extraction could simultaneously address both food and environmental concerns. This study uses a microwave method to extract coffee grounds into coffee ground base oil at four different extraction temperatures. The basic properties were tested, and the optimal extraction temperature was selected. The coffee ground base oil from the optimal extraction temperature was then formulated into three different water content levels with and without an alkaline additive, resulting in a total of six coffee ground lubricant combinations. These were compared with commercial grinding and cutting oils in terms of basic properties and tribological performance. The main results are as follows: (1) Coffee ground base oil extracted at 420 °C, when formulated with 92% water content, had the lowest total acid number (23.1 mg KOH/g), the highest pH value (4.03), and the best extraction yield (26%), making it the optimal choice among the four extraction temperatures in terms of comprehensive properties and cost. (2) The coffee ground base oil produced in this process can mix uniformly with water without the need for emulsifying additives, avoiding oil-water separation and reducing the microbial growth and odor issues commonly associated with emulsifiers. (3) According to iii industry-standard oxidation visual inspection and component analysis, the lubricating oil extracted from coffee grounds does not cause oxidation or corrosion in any of the three types of aluminum alloys. (4) The carbonized coffee grounds left after extracting the coffee ground lubricant can be used as biochar for soil improvement and carbon sequestration, making this manufacturing method a zero-waste circular economy product. (5) The total acid number and contact angle of the coffee ground lubricant increase with water content, while the pH value and viscosity decrease with increasing water content. (6) Under the experimental parameters, the coffee ground lubricant with 92% water content exhibited the lowest contact angle, resulting in lower wear and average friction compared to both the alkaline additive-enhanced coffee ground lubricant and commercial grinding and cutting oils. (7) The lubricating oil extracted from coffee grounds at a refining temperature of 420°C and a water content of 92% has the potential to replace semi-synthetic grinding and cutting oils in terms of friction, wear, and corrosion resistance properties. Moreover, this represents the world's first method for extracting lubricating oil from coffee grounds. (8) Based on the friction variation in coffee ground lubricants with water contents of 87%, 92%, and 97%, it is recommended to use a water content range of 89% to 94% as the standard for factory water or oil addition..
