Description
本發明是有關於一種塑膠，特別是指一種含有咖啡材料的塑膠母粒的製法。The invention relates to a plastic, in particular to a method for preparing a plastic masterbatch containing a coffee material.
咖啡豆具有獨特的香氣，利用咖啡豆沖泡出來的咖啡，為一種廣為大眾所喜愛的飲品。咖啡豆沖泡過後所產生的咖啡渣，於日常生活中尚有其他用途。例如可將咖啡渣擺放在鞋櫃、衣櫥、浴室等地方，除了可以除臭外，還可以留下咖啡的香味。正因為咖啡渣的此種特性，晚近有業者將咖啡渣與其他材料混合，製作出含有咖啡材料的成品。以咖啡渣製得的成品，除了能具有前述的優點外，因將原本會被丟棄的咖啡渣再生利用，還相當環保。Coffee beans have a unique aroma, and coffee brewed from coffee beans is a popular drink. The coffee grounds produced after the coffee beans are brewed have other uses in daily life. For example, the coffee grounds can be placed in a shoe cabinet, a closet, a bathroom, etc., in addition to deodorizing, the fragrance of the coffee can be left. Because of this characteristic of coffee grounds, latecomers have mixed coffee grounds with other materials to produce finished products containing coffee materials. The finished product made from coffee grounds, in addition to the above-mentioned advantages, is also environmentally friendly because it recycles the coffee grounds that would otherwise be discarded.
將咖啡渣等咖啡材料與其他材料混合時，常會出現咖啡材料與其他材料相分離的問題，使製作出來的成品出現物性不佳或者物性不均的情況。咖啡材料中所含有的油脂，如不妥善處理，除了會有導致前述的相分離問題外，製作為成品後，還會變質發臭。目前將油脂移除的作法大多是利用有機溶劑萃取，但購買有機溶劑與後續的廢液處理均會提高生產成本，消費者對於經有機溶劑處理的產品，也會產生危害健康的疑慮。因此，如何製作出含有咖啡材料且物性良好均一的環保成品，且製造過程中無需使用有機溶劑，是一值得挑戰的問題。When a coffee material such as coffee grounds is mixed with other materials, there is often a problem that the coffee material is separated from other materials, resulting in poor physical properties or uneven physical properties of the finished product. If the oil contained in the coffee material is not properly handled, in addition to the above-mentioned phase separation problem, it will deteriorate and become odor after being made into a finished product. At present, most of the oil removal methods are extracted by organic solvents, but the purchase of organic solvents and subsequent waste treatment will increase the production cost, and consumers will have health concerns about organic solvent-treated products. Therefore, how to make an environmentally-friendly finished product containing a coffee material and having good physical properties, and eliminating the need to use an organic solvent in the manufacturing process is a problem that is worth challenging.
本發明的目的，在於提供一種含有咖啡材料的塑膠母粒的製法，能製造出物性良好均一的環保成品，且過程中不使用有機溶劑。It is an object of the present invention to provide a method for preparing a plastic masterbatch containing a coffee material, which can produce an environmentally-friendly finished product having good physical properties and without using an organic solvent in the process.
該含有咖啡材料的塑膠母粒的製法，包含：The method for preparing the plastic masterbatch containing coffee material comprises:
步驟A：提供咖啡原料，並以100W℃至250℃的條件，加熱該咖啡原料。步驟B：將該咖啡原料研磨至粒徑為100µm至500µm，加入分散劑，得到混合物。所述的分散劑選自於碳酸鈣、滑石粉，以及前述材料的任一種組合。步驟C：將該混合物與聚乳酸原料製成含有咖啡材料的塑膠母粒。Step A: Providing a coffee raw material and heating the coffee raw material at a temperature of from 100 WC to 250 °C. Step B: The coffee raw material is ground to a particle diameter of from 100 μm to 500 μm, and a dispersing agent is added to obtain a mixture. The dispersing agent is selected from the group consisting of calcium carbonate, talc, and any combination of the foregoing. Step C: The mixture and the polylactic acid raw material are made into a plastic masterbatch containing a coffee material.
所使用的咖啡原料，能使用咖啡豆沖泡後所產生的咖啡渣，此種咖啡原料的成本較為低廉。實際上，由於該步驟B中還會進一步研磨，因此也能使用過期的咖啡豆、新鮮的咖啡豆等未經沖泡及研磨的咖啡豆，但會提高製作成本。此外，使用咖啡渣作為咖啡原料，還具有將原本會被丟棄的廢物再生利用的環保優點。The coffee raw material used can be made from coffee grounds produced by brewing coffee beans, and the cost of such coffee raw materials is relatively low. In fact, since the step B is further ground, it is also possible to use unfilled and ground coffee beans such as expired coffee beans or fresh coffee beans, but the production cost is increased. In addition, the use of coffee grounds as a coffee raw material also has the environmental advantage of recycling waste that would otherwise be discarded.
於該步驟A中，如加熱的溫度低於100℃，將無法去除油脂；如加熱的溫度高於250℃，則又會有使咖啡原料碳化變質的可能。In this step A, if the heating temperature is lower than 100 ° C, the grease cannot be removed; if the heating temperature is higher than 250 ° C, there is a possibility that the coffee raw material is carbonized and deteriorated.
於該步驟B中，如咖啡原料的粒徑大於500µm，將不利後續咖啡原料與聚乳酸原料混合均勻；如咖啡原料的粒徑小於100µm，由於咖啡原料的表面積過大，表面能過高，雖利於混合，但混合後的成品因表面能過大而不穩定，也容易有小規模的相分離現象發生。In the step B, if the particle diameter of the coffee raw material is more than 500 μm, the unfavorable subsequent coffee raw material and the polylactic acid raw material are uniformly mixed; if the particle diameter of the coffee raw material is less than 100 μm, the surface energy is too high due to the excessive surface area of the coffee raw material, although it is advantageous for Mixed, but the mixed product is unstable due to excessive surface energy, and it is easy to have small-scale phase separation.
該分散劑除了能讓後續製得的成品性質穩定，不輕易產生相分離外，還具有能夠吸收油脂提高產品品質的優點。該分散劑能於該咖啡原料研磨前或研磨後加入。較佳地，該分散劑是於該咖啡原料研磨前加入，並一起研磨。In addition to the stability of the finished product obtained, the dispersant does not easily cause phase separation, and has the advantage of being able to absorb grease and improve product quality. The dispersant can be added before or after grinding of the coffee material. Preferably, the dispersing agent is added before the coffee raw material is ground and ground together.
較佳地，以該咖啡原料的總重為100重量份，該分散劑的使用量為5至10重量份。當分散劑的使用量介於前述的限定範圍中時，所製得的成品更不容易出現相分離的情況，成品也能取得較佳的除臭效果及提供咖啡香的效果。Preferably, the dispersing agent is used in an amount of 5 to 10 parts by weight based on 100 parts by weight of the total of the coffee raw material. When the amount of the dispersant used is within the above-defined range, the obtained finished product is less prone to phase separation, and the finished product can also achieve a better deodorizing effect and provide a coffee fragrance effect.
本發明所使用的聚乳酸原料，常被應用於醫學領域中，具有對人體較為安全的性質，且為一種可降解材料，能於大自然中被分解，相當環保。The polylactic acid raw material used in the invention is often used in the medical field, has a relatively safe property to the human body, and is a degradable material which can be decomposed in nature and is quite environmentally friendly.
該含有咖啡材料的塑膠母粒的製法的功效在於：利用100℃以上的高溫去除油脂，並利用分散劑吸收油脂且使咖啡材料均勻分散於聚乳酸材料中，故能製造出物性良好均一的成品，且過程中不使用有機溶劑，還能用於將廢物再生利用，相當環保安全。The method for preparing the plastic masterbatch containing the coffee material has the advantages of removing the oil by using a high temperature of 100 ° C or higher, and absorbing the oil by the dispersing agent and uniformly dispersing the coffee material in the polylactic acid material, thereby producing a finished product having good physical properties. And the process does not use organic solvents, but also can be used to recycle waste, which is quite environmentally safe.

該混合研磨步驟12，是以該咖啡原料的總重為100重量份，加入5重量份的碳酸鈣後，放入研磨機研磨，研磨成為平均粒徑300µm的混合物。如何調整研磨機的參數，以研磨出特定粒徑的技術，為本發明所屬技術領域的通常知識者，所具有的普通技能，因此在此省略說明。In the mixing and polishing step 12, 5 parts by weight of calcium carbonate was added in an amount of 100 parts by weight based on the total weight of the coffee raw material, and the mixture was ground in a grinder and ground to obtain a mixture having an average particle diameter of 300 μm. The technique of how to adjust the parameters of the grinder to grind out a specific particle size is a common skill of a person skilled in the art to which the present invention pertains, and thus the description is omitted here.
該母粒製造步驟13，是將該混合物放入射出成型機中，熔融後抽絲再切段成為含有咖啡材料的塑膠母粒。由於射出成型技術也為本發明所屬技術領域之通常知識者所具有的普通技能，因此在此省略說明。In the masterbatch manufacturing step 13, the mixture is placed in a molding machine, melted, and then drawn into a plastic masterbatch containing a coffee material. Since the injection molding technique is also a general skill possessed by a person skilled in the art to which the present invention pertains, the description is omitted here.
本發明所製得的含有咖啡材料的塑膠母粒，可進一步加工製成各式塑膠用品。例如，垃圾桶、水桶、置物盒、塑膠袋、餐飲用具等等。利用本發明製得的成品，因物性良好均一，可應用的物品相當多，且所製造出來的物品，除了不會有難聞的塑膠味外，還會帶有淡淡的咖啡香，更棒的是還能有除臭效果。此外，要特別強調的是，本實施例是以咖啡渣作為咖啡原料，因將原本要被丟棄的咖啡渣再生利用，故相當環保。The plastic masterbatch containing the coffee material prepared by the invention can be further processed into various plastic articles. For example, trash cans, buckets, storage boxes, plastic bags, dining utensils, and the like. The finished product obtained by the invention has good physical properties, and has a large number of applicable articles, and the manufactured articles have a slight coffee fragrance in addition to an unpleasant plastic taste, and even better There is also a deodorizing effect. In addition, it is particularly emphasized that this embodiment uses coffee grounds as a coffee raw material, and is environmentally friendly because it recycles coffee slag which is originally discarded.
