Description
本發明係關於一種具有墊片之瓶蓋之製程與一種低分子量之高流動性之矽膠應用於瓶蓋墊片製程之材料配方開發。 The invention relates to the development of a material formulation for a bottle cap gasket process with a gasket cap process and a low molecular weight high fluidity gel.
金屬爪蓋大多採用鋁板或鍍錫薄板製造，內襯聚氯乙烯(PVC)墊片，多用於廣口瓶包裝，密封罐體藉以保存罐體內容物之新鮮度。 The metal claw cover is mostly made of aluminum plate or tin plate, and is lined with polyvinyl chloride (PVC) gasket, which is mostly used for jar packaging, and the can body is sealed to preserve the freshness of the contents of the can.
現今的金屬爪蓋內墊是由聚氯乙烯(PVC)乳化粉加入可塑劑、填充劑等配方調製而成的膠料，一般常用於桌巾、膠布等柔軟、具可撓曲特性的產品，但要形成此柔軟的特性，需加入高含量的可塑劑，通常在80~100phr的高含量，因此材料中的可塑劑非常容易在使用後釋出至表面，進而遷移到食品內容物中，容易有食安問題的疑慮。 Today's metal claw cover inner pad is a rubber compound prepared by adding a polyvinyl chloride (PVC) emulsified powder to a plasticizer, a filler, etc., and is generally used for soft, flexible products such as tablecloths and tapes. However, in order to form this soft characteristic, a high content of plasticizer is required, usually at a high content of 80 to 100 phr, so that the plasticizer in the material is easily released to the surface after use, and then migrates to the food content, which is easy. There are doubts about food safety issues.
近年來由於食品安全與環保問題日益重視，使得替代聚氯乙烯(PVC)之新材料開發成為刻不容緩的議題，不過聚氯乙烯(PVC)本身加工容易、物性良好且價格便宜，因此在替代性材料不易達到種種訴求基於前述該些 理由，有必要發明一種替代性材料以改善聚氯乙烯(PVC)造成之食品安全與環保問題。 In recent years, due to the increasing emphasis on food safety and environmental protection issues, the development of new materials for replacing polyvinyl chloride (PVC) has become an urgent issue. However, polyvinyl chloride (PVC) itself is easy to process, has good physical properties and is inexpensive, so it is in alternative materials. It is not easy to reach all kinds of appeals based on the aforementioned For reasons, it is necessary to invent an alternative material to improve food safety and environmental protection caused by polyvinyl chloride (PVC).
為了解決現有金屬爪蓋使用聚氯乙烯(PVC)墊片所造成的食品安全與環保問題，本發明提出一種高流動性之矽膠的改質方法與配方應用於金屬爪蓋之墊片，本發明所選用之成分，皆通過美國食品藥物安全管理局(FDA)認證或食品級原料，因此不但無食品安全之疑慮，且回收後直接焚燒亦不會有環境汙染之虞，並可完全符合現有金屬爪蓋廠墊片之生產加工製程，解決現階段如熱塑性硫化橡膠(TPV)、熱塑性聚胺酯彈性體(TPU)類彈性體材料想要進行試料卻無法直接在既有產線上直接導入試產等諸多問題。 In order to solve the food safety and environmental protection problems caused by the use of polyvinyl chloride (PVC) gaskets in the existing metal claw cover, the present invention provides a high fluidity silicone rubber modification method and formulation applied to the metal claw cover gasket, the present invention The ingredients selected are all certified by the US Food and Drug Administration (FDA) or food-grade ingredients. Therefore, there is no doubt about food safety, and there is no environmental pollution caused by direct incineration after recycling, and it can fully comply with existing metals. The production process of the claw cover factory gasket solves many problems such as thermoplastic vulcanizate (TPV) and thermoplastic polyurethane elastomer (TPU) elastomer materials, but it is not possible to directly introduce the trial production directly on the existing production line. .

請參考圖1，將第一高流動性之矽膠原膠A 50phr置入預拌槽10中，再加入粉體填充劑C，其中該粉體填充劑C包含0.5phr之鈦白粉(TiO2)與10phr之矽酸鹽類玻璃粉，待該鈦白粉充分分散後，再加入該矽酸鹽類玻璃粉進行混練。而後將稀釋助劑D加入進行稀釋，其中，該稀釋助劑D包含100phr之矽油、100phr之四環體矽油及5phr之食品級白臘油；將混練完成之該第一高流動性之矽膠原膠A、該粉體填充劑C與該稀釋助劑D置入該儲存槽11中儲存，再將一第二高流動性之矽膠原膠B與混練好之該第一高流動性之矽膠原膠A置於該混膠模12組進行混膠製成該改質矽膠料(編號LSR-3)，再將該混膠完成之該改質矽膠料導入一點膠設備13，使用注射方式以旋轉塗佈機台進行該改質矽膠料之塗佈，並在旋轉離心過程中同時達到消泡與分散的效果。將已塗佈完成之該金屬爪蓋以烘箱進行交聯製程，在150℃，5分鐘內熟化完畢。其中，該第一高流動性之矽膠原膠A與該第二高流動性之矽膠原膠B之其他改質方法，請參考實施方式中之混練改質步驟。 Referring to FIG. 1, the first high-flowing bismuth collagen A 50 phr is placed in the premixing tank 10, and then the powder filler C is added, wherein the powder filler C contains 0.5 phr of titanium dioxide (TiO 2 ). With 10 phr of citrate glass powder, after the titanium white powder is sufficiently dispersed, the silicate type glass powder is further added for kneading. Then, the dilution aid D is added to be diluted, wherein the dilution aid D comprises 100 phr of eucalyptus oil, 100 phr of tetracyclic eucalyptus oil and 5 phr of food grade leuco oil; the first high fluidity 矽 collagen is completed by mixing. The glue A, the powder filler C and the dilution aid D are placed in the storage tank 11 for storage, and a second high-flowing 矽 collagen glue B is mixed with the first high-flow 矽 collagen. The glue A is placed in the rubber mold 12 group to be mixed to prepare the modified rubber compound (No. LSR-3), and the modified rubber compound obtained by the rubber mixing is introduced into the one-point glue device 13 by using the injection method. The coating machine is applied by the spin coating machine, and the effect of defoaming and dispersing is simultaneously achieved during the rotary centrifugation. The metal claw cover which has been coated is subjected to a cross-linking process in an oven, and is aged at 150 ° C for 5 minutes. For the modification method of the first high fluidity collagen gel A and the second high fluidity collagen gel B, please refer to the kneading modification step in the embodiment.
以下為測試交聯完成之該金屬爪蓋之加工性。 The following is the processability of the metal claw cover which is tested for cross-linking.
在測試該高流動性之矽膠瓶蓋墊片配方之硫化時間(秒)，其結果如下表1所示，其中t10為硫化時間達完全固化之10%之程度；t50為硫化時間達其固化之50%之程度；t90為硫化時間達其固化之90%之程度。當t10的時間較長時，代表混合兩種可供改質後之該第一高流動性之矽膠原膠A與改質後之該第二 高流動性之矽膠原膠B於混合後仍保持高度流動狀態的時間，本實施例測試結果顯示，該第一高流動性之矽膠原膠A及第二高流動性之矽膠原膠B混合後仍有50秒以上，因此具有相當的的工作時間範圍，有利於製造過程的轉移運輸。 The vulcanization time (seconds) of the high fluidity silicone cap gasket formulation was tested. The results are shown in Table 1 below, wherein t10 is the vulcanization time to the extent of 10% of complete curing; t50 is the curing time to cure. 50% degree; t90 is the degree of vulcanization time to 90% of its curing. When the time of t10 is long, it means mixing the two first high-flowing collagen gels A which can be modified and the second one after the modification. The high fluidity of the collagen gel B remains highly flowing after mixing. The test results of this example show that the first high fluidity collagen gel A and the second high fluidity collagen gel B are mixed. There are still more than 50 seconds, so there is a considerable working time range, which is conducive to the transfer of the manufacturing process.
該高流動性之矽膠瓶蓋墊片配方之黏度值量測結果如表2所示，其黏度質均大於6000Cps，於目測可達成目測不流動之狀態。 The viscosity measurement results of the high-flow silicone cap gasket formulation are shown in Table 2. The viscosity is greater than 6000 Cps, and the visual measurement can be achieved without visual observation.
該高流動性之矽膠瓶蓋墊片配方之耐高溫測試結果如表3所示，測試方式係以目測方式觀測成品之固形狀態，是否有黏糊狀產生以判斷可否使用，結果顯示均能滿足要求。 The high-temperature test results of the high-flow silicone cap gasket formulation are shown in Table 3. The test method is to observe the solid state of the finished product by visual inspection, and whether there is a sticky appearance to judge whether it can be used or not. The results show that the requirements can meet the requirements. .
該高流動性之矽膠瓶蓋墊片配方之旋蓋扭力值量測結果可如下表4所示，實際的扭力值介於36~38，該扭力數值係測試旋蓋可讓一般使用者平均施力得以打開。 The measurement result of the screw cap torque value of the high-flow silicone cap gasket formulation can be as shown in Table 4 below, and the actual torque value is between 36 and 38. The torque value is the test screw cap which can be applied by the average user. The force was opened.
