橡膠組成物及應用該組成物的橡膠複合層製造方法 Rubber composition and method for producing rubber composite layer using the same

本發明有關於一種橡膠組成物及其應用，且特別是有關於橡膠組成物及應用該組成物的橡膠層製造方法。 The present invention relates to a rubber composition and its use, and in particular to a rubber composition and a method of producing a rubber layer using the same.

現今對於薄化橡膠製品的應用越來越廣泛，比如做為耐燃防護衣、工業雨衣、醫療床罩的主要材質。但在充氣筏製品上仍使用厚度較厚且重量較重的橡膠皮料，因此，製成成品後的重量會造成搭載船的負荷。在現有的橡膠工業中，由於橡膠無法在過高的溫度下加工，要將橡膠壓薄至0.1釐米，在技術上已具有一定的難度。並且，用作充氣筏製品的橡膠皮料對於氣密性、接著性、機械強度、耐油、耐水、抗紫外線以及耐寒等性質要求甚高，以期適用於惡劣的環境。 Nowadays, the application of thinned rubber products is more and more extensive, such as the main material of fire resistant protective clothing, industrial raincoat and medical bed cover. However, a thicker and heavier rubber material is still used on the inflatable enamel product, so that the weight of the finished product causes a load on the ship. In the existing rubber industry, since the rubber cannot be processed at an excessively high temperature, it is technically difficult to press the rubber to 0.1 cm. Moreover, the rubber leather used as an inflatable enamel product is highly demanding for airtightness, adhesion, mechanical strength, oil resistance, water resistance, ultraviolet resistance, and cold resistance, and is intended to be suitable for use in a harsh environment.

另外，在加工充氣筏的橡膠皮料時，其中一道工序是將黏著劑塗佈於橡膠皮料的兩相對表面，再將橡膠皮料捲起，使塗佈黏著劑的兩相對表面相互黏著貼合，並要求黏合時的強度至少75N/5cm以上。日後對充氣筏以高壓充氣時，才能盡量避免充氣筏接縫氣爆的危險。因此，如何開發重量輕，同時又符合上述需求的薄化橡膠皮料，以應用於充氣型產品，或進一步應用於其他領域，為當今業界所欲追求的目標。 In addition, in the processing of the rubber material of the inflatable concrete, one of the steps is to apply the adhesive to the opposite surfaces of the rubber leather, and then roll the rubber material to adhere the two opposite surfaces of the coating adhesive to each other.

請參照圖1，為本發明實施例製作橡膠層的流程圖。包含下列步驟：首先，進行步驟S10，提供一橡膠組成物。所述的橡膠組成物至少包括添加40至60重量份(PHR)的天然膠、20至40重量份的氯丁橡膠、20至40重量份的乙丙烯橡膠、100至200重量份的無機填充劑、5至20重量份的有機填充劑；及2至5重量份之硫化劑。 Please refer to FIG. 1 , which is a flow chart of manufacturing a rubber layer according to an embodiment of the present invention. The following steps are included: First, step S10 is performed to provide a rubber composition. The rubber composition includes at least 40 to 60 parts by weight (PHR) of natural rubber, 20 to 40 parts by weight of chloroprene rubber, 20 to 40 parts by weight of ethylene propylene rubber, and 100 to 200 parts by weight of an inorganic filler. And 5 to 20 parts by weight of an organic filler; and 2 to 5 parts by weight of a vulcanizing agent.

其中，無機填充劑選自碳酸鈣、黏土、鍛燒土及其混合所組成的群組其中之一種；有機填充劑選自硬酯酸、樹酯、凡士林及其混合所組成的群組其中之一種。而硫化劑選自由硫磺、有機促進劑及氧化鋅組成的群組其中之一種。有機或無機填充劑可增加橡膠製品的硬度、抗張強度、耐磨性及抗撕裂性，而硫化劑則用以使橡膠組成物高溫時，產生固化反應。 Wherein, the inorganic filler is selected from the group consisting of calcium carbonate, clay, calcined earth and a mixture thereof; the organic filler is selected from the group consisting of stearic acid, resin, petrolatum and a mixture thereof. One. The vulcanizing agent is selected from the group consisting of sulfur, an organic accelerator, and zinc oxide. The organic or inorganic filler can increase the hardness, tensile strength, abrasion resistance and tear resistance of the rubber product, and the vulcanizing agent is used to cause the curing reaction when the rubber composition is at a high temperature.

除了上述組成之外，也可視情況加入其他種類添加劑，比如：抗氧化劑、色料等等。 In addition to the above composition, other kinds of additives such as antioxidants, colorants and the like may be added as the case may be.

接著，於步驟S11中，混煉上述橡膠組成物，並在一第一預定溫度下將橡膠組成物充分混合。在本發明實施例中，將所述的橡膠組成物之膠料利用混煉機混煉，例如是萬馬力混煉機，並在50~95℃的環境下經二滾輪(包含粗輪、細輪)充分混合。 Next, in step S11, the above rubber composition is kneaded, and the rubber composition is thoroughly mixed at a first predetermined temperature. In the embodiment of the present invention, the rubber composition of the rubber composition is kneaded by a kneader, for example, a 10,000-horse mixer, and is subjected to two rollers (including a coarse wheel and a fine) in an environment of 50 to 95 ° C. Round) fully mixed.

於步驟S12中，在一第二預定溫度下，將橡膠組成物壓延至一設定厚度，形成一橡膠層。本發明實施例中，是將橡膠組合物的膠料以輸送帶送入壓延貼合機中。若壓延時的溫度太高，會使 橡膠產生硫化反應而產生熱固性彈性體，使橡膠變硬，就無法再繼續加工壓薄到預定的厚度。若壓延時溫度太低，橡膠韌性太大，無法壓延至指定厚度。本發明實施例中，壓延時的第二預定溫度控制在60至95℃，可將橡膠層壓延至0.07釐米至0.1釐米。 In step S12, the rubber composition is calendered to a set thickness at a second predetermined temperature to form a rubber layer. In the embodiment of the present invention, the rubber composition is fed into the calendering laminating machine as a conveyor belt. If the temperature of the delay is too high, it will The rubber generates a vulcanization reaction to produce a thermosetting elastomer, which makes the rubber hard and can no longer be processed and pressed to a predetermined thickness. If the press delay temperature is too low, the rubber is too tough and cannot be calendered to the specified thickness. In the embodiment of the present invention, the second predetermined temperature of the press delay is controlled at 60 to 95 ° C, and the rubber lamination can be extended to 0.07 cm to 0.1 cm.

請參照圖2，為本發明實施例雙面橡膠複合層的製造方法，包括下列步驟：於步驟S20中，提供一基布，基布具有相對的上表面與下表面。本實施例的基布為尼龍基布或聚酯纖維布，且為高強度輕量型的強力紗，以可減輕成品的重量。但並不僅限於這兩種材質，也可依據應用的領域，選擇其他種類。 Referring to FIG. 2, a method for manufacturing a double-sided rubber composite layer according to an embodiment of the present invention includes the following steps: In step S20, a base fabric is provided, the base fabric having opposite upper and lower surfaces. The base fabric of the present embodiment is a nylon base fabric or a polyester fiber cloth, and is a high-strength and lightweight type strong yarn to reduce the weight of the finished product. However, it is not limited to these two materials, but other types can be selected depending on the field of application.

接著，於步驟S21中，將基布含浸於一接著劑中。本實施例中，接著劑的黏度約5至50 cps，接著劑例如(但不限於)氯丁橡膠糊、天然膠糊、氯磺化橡膠糊等等。 Next, in step S21, the base fabric is impregnated in an adhesive. In this embodiment, the adhesive has a viscosity of about 5 to 50 cps, and an adhesive such as, but not limited to, a neoprene paste, a natural paste, a chlorosulfonated rubber paste, or the like.

於步驟S22中，分別塗佈一第一接著層及一第二接著層於基布的上表面及下表面。本實施例中，所述的第一接著層及第二接著層材料例如(但不限於)氯丁橡膠糊、天然膠糊及氯磺化橡膠糊等等。倘若雙面橡膠複合層欲使用於製作充氣筏，則第一接著層及第二接著層的黏度控制必須精確。在一實施例中，第一接著層及第二接著層黏度較前一步驟的接著劑黏度高，約200至300cps。 In step S22, a first adhesive layer and a second adhesive layer are respectively coated on the upper surface and the lower surface of the base fabric. In this embodiment, the first adhesive layer and the second adhesive layer material are, for example, but not limited to, a neoprene paste, a natural paste, a chlorosulfonated rubber paste, and the like. If the double-sided rubber composite layer is to be used in the production of an inflatable raft, the viscosity control of the first adhesive layer and the second adhesive layer must be precise. In one embodiment, the first adhesive layer and the second adhesive layer have a higher viscosity than the adhesive of the previous step, about 200 to 300 cps.

於步驟S23中，形成第一橡膠層及第二橡膠層，分別披覆於第一接著層及第二接著層上。在本發明實施例中，形成第一橡膠層及第二橡膠層時，是採用圖1之實施例的製作方法，包括提供前述橡膠組成物，接著將橡膠組成物混煉，並在50至95℃溫度下將橡膠組成物充分混合；施以一壓延製程，在60至95℃溫度下將橡膠組成物，壓延至厚度0.07至0.1釐米，以形成所述的第一橡膠層，再將第一橡膠層貼合於第一接著層上。 In step S23, a first rubber layer and a second rubber layer are formed and coated on the first adhesive layer and the second adhesive layer, respectively. In the embodiment of the present invention, when the first rubber layer and the second rubber layer are formed, the manufacturing method of the embodiment of FIG. 1 is adopted, including providing the rubber composition, and then kneading the rubber composition at 50 to 95. The rubber composition is thoroughly mixed at a temperature of ° C; a calendering process is applied, and the rubber composition is calendered to a thickness of 0.07 to 0.1 cm at a temperature of 60 to 95 ° C to form the first rubber layer, and then the first The rubber layer is attached to the first adhesive layer.

接著，重複上述的壓延製程，將橡膠組成物壓延形成一第二橡膠層，並將第二橡膠層以壓延貼合機貼合於第二接著層上。 Next, the above-described calendering process is repeated, the rubber composition is calendered to form a second rubber layer, and the second rubber layer is bonded to the second subsequent layer by a calendering laminator.

於步驟S24中，披覆一織物於第一橡膠層及第二橡膠層上。本發明實施例中，織物例如：為尼龍基布、聚酯纖維布、棉布、玻璃纖維、聚酯尼龍纖維混紡紗布及其他不同組成纖維的混紡紗布其中之一者。 In step S24, a fabric is coated on the first rubber layer and the second rubber layer. In the embodiment of the present invention, the fabric is, for example, one of a nylon-based cloth, a polyester fiber cloth, a cotton cloth, a glass fiber, a polyester-nylon fiber-blended gauze, and other blended gauze of different constituent fibers.

在另一實施例中，雙面橡膠複合層將用來製作充氣筏，因此第一橡膠層與第二橡膠層表面將塗佈接著劑，以相互黏合，黏合的強度需要至少75N/5cm。在第一橡膠層及第二橡膠層上披覆織物，可使第一橡膠層及第二橡膠層表面產生壓紋，形成凹凸表面，而增加橡膠層表面積。換句話說，橡膠層表面與接著劑的接觸面積也會增加，而提高橡膠層之間的黏合強度。 In another embodiment, the double-sided rubber composite layer will be used to make an inflatable crucible, so that the first rubber layer and the second rubber layer surface will be coated with an adhesive to adhere to each other, and the bonding strength needs to be at least 75 N/5 cm. Coating the fabric on the first rubber layer and the second rubber layer causes embossing on the surfaces of the first rubber layer and the second rubber layer to form a concave-convex surface and increase the surface area of the rubber layer. In other words, the contact area of the surface of the rubber layer with the adhesive is also increased, and the bonding strength between the rubber layers is increased.

於步驟S25中，進行一硫化處理，使第一橡膠層及第二橡膠層架橋固化。本發明實施例中，是在130至160℃的溫度下進行硫化處理。 In step S25, a vulcanization treatment is performed to cure the first rubber layer and the second rubber layer. In the embodiment of the present invention, the vulcanization treatment is carried out at a temperature of 130 to 160 °C.

於步驟S26中，移除織物。在硫化處理後，將用於產生紋路之織物取下，此時第一及第二橡膠層表面即具有紋路，形成三層之雙面橡膠複合層。 In step S26, the fabric is removed. After the vulcanization treatment, the fabric for producing the texture is removed, and at this time, the surfaces of the first and second rubber layers have a texture to form a three-layer double-sided rubber composite layer.

本發明提出雙面橡膠複合層之製作方法，以高強度輕量型的強力紗為基布，在其雙面貼合超薄橡膠層，使成品重量每平方公尺僅400 g，機械強度高、耐油、耐水、抗紫外光且耐寒可達-40℃，極適合用於惡劣的環境，可應用於製作充氣筏、充氣型產品或進一步應用於其他領域。另外，在橡膠層表面可選擇性設有壓印紋路，製成充氣筏時，增加接著劑與橡膠層表面的接觸面積，提高黏合強度，而具有高氣密及高接著性，可避免充氣筏充氣時，接縫發生氣爆。 The invention provides a method for manufacturing a double-sided rubber composite layer, which comprises a high-strength and light-weight strong yarn as a base fabric, and an ultra-thin rubber layer is attached on both sides thereof, so that the weight of the finished product is only 400 g per square meter, and the mechanical strength is high. It is oil-resistant, water-resistant, UV-resistant and cold-resistant up to -40 ° C. It is suitable for use in harsh environments and can be used to make inflatable rafts, inflatable products or further applications in other fields. In addition, an imprinting pattern can be selectively provided on the surface of the rubber layer, and when the inflatable crucible is formed, the contact area between the adhesive and the surface of the rubber layer is increased, the bonding strength is improved, and the airtightness and high adhesion are avoided, thereby avoiding inflation. When inflated, the seams are exploding.

以上所述僅為本發明的實施例，其並非用以限定本發明的專利保護範圍。任何熟習相像技藝者，在不脫離本發明的精神與範圍內，所作的更動及潤飾的等效替換，仍為本發明的專利保護範圍內。 The above is only an embodiment of the present invention, and is not intended to limit the scope of the invention. It is still within the scope of patent protection of the present invention to make any substitutions and modifications of the modifications made by those skilled in the art without departing from the spirit and scope of the invention.
