Abstract
本發明之課題在於提供一種對所有剪切方向之外力均顯示出穩定之黏著特性且二次加工性優異之線狀黏著體之貼附方法。本發明係關於一種線狀黏著體之貼附方法，其包括藉由下述形狀將線狀黏著體貼附於被黏著體之步驟，此處，形狀係如下形狀：於貼附有線狀黏著體之ABS樹脂板之上述線狀黏著體之上進而配置ABS樹脂板並實施拉伸試驗，將產生剪切破壞之時點之負載[N]換算成線狀黏著體對ABS樹脂板之接著面積之每單位面積[mm 2]而獲得剪切強度[N/mm 2]，針對所獲得之剪切強度，該剪切強度成為最大之方向之剪切強度Q(0°)與和剪切強度成為最大之方向呈90°之方向之剪切強度Q(90°)滿足下述關係。 1.0≦Q(0°)/Q(90°)＜1.1 An object of the present invention is to provide a method for attaching a linear adhesive body that exhibits stable adhesive properties against external forces in all shearing directions and has excellent secondary workability. The present invention relates to a method for attaching a linear adhesive body, which includes the step of attaching the linear adhesive body to an adherend through the following shape, where the shape is the following shape: on the surface to which the linear adhesive body is attached An ABS resin plate is placed on the above-mentioned linear adhesive body of the ABS resin plate and a tensile test is performed. The load [N] at the point when shear failure occurs is converted into one unit of the contact area of the linear adhesive body to the ABS resin plate. The area [mm 2 ] is used to obtain the shear strength [N/mm 2 ]. For the obtained shear strength, the shear strength Q (0°) in the direction in which the shear strength becomes the maximum is equal to the shear strength Q(0°) in which the shear strength becomes the maximum. The shear strength Q (90°) in the direction of 90° satisfies the following relationship. 1.0≦Q(0°)/Q(90°)<1.1
Description
本發明係關於一種線狀黏著體之貼附方法及線狀黏著體接合體。The present invention relates to a method for attaching a linear adhesive and a linear adhesive joint.
於將2種以上之物品貼合時，有時使用雙面膠帶等黏著構件，但於要貼合之物品之形狀複雜之情形或接著區域較窄之情形時，難以貼合。又，為了實施上述情況之貼合，必須將雙面膠帶切斷成寬度較寬或進行沖切加工，工時及廢棄物量較多，於總成本而言不利。進而，由於雙面膠帶之基材強度不充分，故無法進行剛體彼此之二次加工。When two or more items are bonded together, adhesive members such as double-sided tape are sometimes used. However, when the items to be bonded have complex shapes or the bonding area is narrow, it is difficult to bond them. In addition, in order to perform the above-mentioned lamination, the double-sided tape must be cut into a wider width or punched, which requires a lot of man-hours and waste, which is disadvantageous in terms of total cost. Furthermore, since the base material of the double-sided tape has insufficient strength, secondary processing of the rigid bodies cannot be performed.
為了解決上述課題，使用線狀黏著體。線狀黏著體由於拉伸強度較高，故即便為包含於剛體彼此之接合體中之狀態，亦可拉伸剝離。又，亦可接著於複雜形狀或微細形狀，且無需帶之後加工，故而於成本方面亦有利。To solve the above problems, a linear adhesive is used. Since the tensile strength of the linear adhesive is high, it can be stretched and peeled even when it is included in the joint of the steel bodies. In addition, it can be attached to complex or fine shapes, and there is no need for post-processing, so it is also cost-effective.
例如，於專利文獻1中記載有一種線狀黏著體，其特徵在於無需剝離紙且可自由地描繪成曲線狀。於專利文獻2中記載有一種線狀之黏著性物品，其具有包含顯示出特定之凝膠分率之黏著劑層之黏著體。於專利文獻3中記載有一種線狀之黏著性物品，其包含具備4根以上之長絲之複絲線作為芯材。For example, Patent Document 1 describes a linear adhesive body, which is characterized in that it does not require peeling paper and can be freely drawn in a curved shape. Patent Document 2 describes a linear adhesive article having an adhesive body including an adhesive layer showing a specific gel fraction. Patent Document 3 describes a linear adhesive article containing a multifilament yarn having four or more filaments as a core material.
另一方面，由於線狀黏著體具有上述優異之特性，故可供於各種各樣之用途。因此，被黏著體經線狀黏著體接合而成之接合體所要求之機械性質亦各種各樣，期待藉由線狀黏著體所實現之黏著特性解決該等要求。 [先前技術文獻] [專利文獻] On the other hand, since the linear adhesive has the above-mentioned excellent characteristics, it can be used in various applications. Therefore, the mechanical properties required for joints formed by joining adherends via linear adhesives are also various, and it is expected that these requirements can be solved by the adhesive properties achieved by linear adhesives.

[發明所欲解決之問題][Problem to be solved by the invention]
然而，於專利文獻1～3中，與用以藉由線狀黏著體使接合體之黏著特性成為所需黏著特性之具體手段相關之記載或暗示皆無。However, Patent Documents 1 to 3 do not describe or suggest any specific means for achieving desired adhesive properties of a bonded body using a linear adhesive.
本發明係鑒於上述而完成者，課題在於提供一種對所有剪切方向之外力均顯示出穩定之黏著特性且二次加工性優異的線狀黏著體之貼附方法。又，本發明之課題在於提供一種藉由該貼附方法貼附線狀黏著體而成之貼附體、及經藉由該貼附方法而貼附之線狀黏著體接合而成之接合體。 [解決問題之技術手段] The present invention was completed in view of the above, and its object is to provide a method for attaching a linear adhesive body that exhibits stable adhesive properties against forces outside the shearing direction and is excellent in secondary workability. Furthermore, an object of the present invention is to provide an attachment body in which a linear adhesive body is attached by the attachment method, and a joint body in which the linear adhesive body is attached by the attachment method. . [Technical means to solve problems]

In addition, in order to clearly explain the present invention, the embodiments described in the drawings are schematic, and the dimensions or scale of actual products are not necessarily shown accurately. Furthermore, when the expression "～" is used in this specification, it is used in a form that includes the numerical or physical property values before and after it.
＜線狀黏著體之貼附方法＞ 本發明之線狀黏著體之貼附方法包括如下步驟：藉由剪切強度成為最大之方向之剪切強度Q(0°)與和上述剪切強度成為最大之方向呈90°之方向之剪切強度Q(90°)滿足下述關係之形狀，將上述線狀黏著體貼附於被黏著體。 1.0≦Q(0°)/Q(90°)＜1.1 <Method for attaching a linear adhesive> The method for attaching a linear adhesive of the present invention comprises the following steps: attaching the linear adhesive to an adherend in a shape where the shear strength Q(0°) in the direction where the shear strength is the maximum and the shear strength Q(90°) in the direction where the shear strength is 90° to the direction where the shear strength is the maximum satisfy the following relationship. 1.0≦Q(0°)/Q(90°)＜1.1
上述關係式中，由於剪切強度成為最大之方向之剪切強度Q(0°)與和上述剪切強度成為最大之方向呈90°之方向之剪切強度Q(90°)處於 Q(0°)≧Q(90°) 之關係，故Q(0°)/Q(90°)之下限值為1.0，不存在未達1.0之情況。 In the above relational expression, the shear strength Q (0°) in the direction in which the shear strength becomes the maximum is in the same relationship as the shear strength Q (90°) in the direction 90° to the direction in which the shear strength becomes the maximum. Q(0°)≧Q(90°) relationship, so the lower limit of Q(0°)/Q(90°) is 1.0, and there is no situation where it does not reach 1.0.
為了使對所有剪切方向之外力之黏著特性穩定，Q(0°)/Q(90°)之最大值較佳為未達1.08，更佳為未達1.05。 若Q(0°)/Q(90°)成為1.1以上，則有根據剪切方向而黏著特性不同之虞。此種貼附方法並不適合要求對所有剪切方向之外力均穩定之黏著特性的用途。 In order to stabilize the adhesion characteristics against external forces in all shear directions, the maximum value of Q(0°)/Q(90°) is preferably less than 1.08, and more preferably less than 1.05. If Q(0°)/Q(90°) becomes greater than 1.1, there is a risk that the adhesion characteristics may differ depending on the shear direction. This attachment method is not suitable for applications that require stable adhesion characteristics against external forces in all shear directions.
(Q(0°)及Q(90°)之測定) 於本發明中，剪切強度成為最大之方向之剪切強度Q(0°)、及與上述剪切強度成為最大之方向呈90°之方向之剪切強度Q(90°)係藉由下述方法求出。 首先，於貼附有線狀黏著體之ABS樹脂板之線狀黏著體之上進而配置ABS樹脂板，並利用加壓機於0.35 MPa之壓力下壓接10秒，獲得樣品用接合體。將樣品用接合體設置於拉伸試驗機，於25℃之溫度條件下以拉伸速度300 mm/min拉伸，於複數個方向求出將產生剪切破壞時之負載[N]換算成線狀黏著體對ABS樹脂板之接著面積之每單位面積[mm 2]所得之剪切強度[N/mm 2]。 (Measurement of Q(0°) and Q(90°)) In the present invention, the shear strength Q(0°) in the direction where the shear strength is the largest and the shear strength Q(90°) in the direction at 90° to the direction where the shear strength is the largest are determined by the following method. First, an ABS resin sheet is placed on the linear adhesive of the ABS resin sheet to which the linear adhesive is attached, and the two are pressed together at a pressure of 0.35 MPa for 10 seconds using a press to obtain a sample joint. The sample was placed in a tensile testing machine with a joint body, and stretched at a temperature of 25°C and a tensile speed of 300 mm/min. The load [N] at which shear failure occurred was converted into the shear strength [N/mm 2 ] per unit area [mm 2 ] of the bonding area of the linear adhesive to the ABS resin sheet in multiple directions.
於上述剪切強度Q(0°)及剪切強度Q(90°)之測定中，2片ABS樹脂板係以即便於利用加壓機於0.35 MPa之壓力下壓接10秒而製成樣品用接合體之後，線狀黏著體亦不會滲出之方式配置。 又，於上述剪切強度Q(0°)及剪切強度Q(90°)之測定中，就使測定結果穩定而言，較佳為以使拉伸方向通過線狀黏著劑之重心之方式將樣品用接合體設置於拉伸試驗機。 In the above-mentioned measurement of shear strength Q (0°) and shear strength Q (90°), two ABS resin plates were pressed together using a press machine at a pressure of 0.35 MPa for 10 seconds to prepare a sample. After the joint body is used, the linear adhesive body is arranged in a way that it will not bleed out. In addition, in the measurement of the above-mentioned shear strength Q (0°) and shear strength Q (90°), in order to stabilize the measurement results, it is preferable to make the tensile direction pass through the center of gravity of the linear adhesive. The sample joint was set in a tensile testing machine.
以如上方式求出之剪切強度中，剪切強度成為最大之方向之剪切強度成為Q(0°)。又，與上述剪切強度成為最大之方向呈90°之方向之剪切強度成為Q(90°)。 再者，於剪切強度成為最大之方向存在複數個之情形時，針對各情形測定Q(0°)及Q(90°)，分別求出Q(0°)/Q(90°)。該等之中，採用成為最大值之Q(0°)/Q(90°)作為本說明書中之Q(0°)/Q(90°)。 Among the shear strengths determined in the above manner, the shear strength in the direction in which the shear strength becomes maximum is Q(0°). Moreover, the shear strength in the direction 90° to the direction in which the above-mentioned shear strength becomes the maximum is Q (90°). In addition, when there are multiple cases in which the shear strength becomes the maximum, Q(0°) and Q(90°) are measured for each case, and Q(0°)/Q(90°) is obtained respectively. Among them, Q(0°)/Q(90°) which is the maximum value is adopted as Q(0°)/Q(90°) in this specification.
於測定剪切強度時，為了使測定結果穩定，用於測定之2片ABS樹脂板較佳為使用相同者。作為用於測定之ABS樹脂板，可使用市售者，例如可使用Kobe Polysheet ABS板(昭和電工材料股份有限公司製造)等。When measuring shear strength, in order to stabilize the measurement results, it is preferable to use the same two ABS resin plates used for measurement. As the ABS resin plate used for measurement, a commercially available one can be used. For example, a Kobe Polysheet ABS plate (manufactured by Showa Denko Materials Co., Ltd.) can be used.
製作樣品用接合體時所使用之加壓機可使用市售者，例如可使用伺服加壓機(日立化成股份有限公司製造)等。 又，樣品用接合體之拉伸試驗所使用之拉伸試驗機可使用市售之裝置，例如可使用AG-X/R(島津製作所股份有限公司製造)等。 The press used in making the sample joint body can be a commercially available press, such as a servo press (manufactured by Hitachi Chemical Co., Ltd.). In addition, the tensile testing machine used in the tensile test of the sample joint body can be a commercially available device, such as AG-X/R (manufactured by Shimadzu Corporation).
(線狀黏著體) 本發明之貼附方法使用線狀黏著體。線狀黏著體即便為包含於剛體彼此之接合體中之狀態，亦可將其拉伸剝離。因此，與先前之使用雙面膠帶之貼附方法相比，二次加工性優異，可容易地再利用被黏著體，本發明之貼附方法於環境方面及成本方面這兩方面優異。 以下，對本發明之貼附方法所使用之線狀黏著體之較佳態樣進行說明。 (Linear adhesive) The pasting method of the present invention uses a linear adhesive. Even when the linear adhesive is contained in a bonded body between two rigid bodies, it can be stretched and peeled off. Therefore, compared with the previous pasting method using double-sided tape, the secondary processability is excellent, and the adherend can be easily reused. The pasting method of the present invention is excellent in both environmental and cost aspects. The following describes the preferred embodiment of the linear adhesive used in the pasting method of the present invention.

再者，作為黏著劑，可使用溶劑型之黏著劑與水分散型之黏著劑之任意類型，較佳為藉由黏著劑組合物之乾燥(溶劑揮發)進行交聯，且乾燥後迅速結束交聯者。其原因在於黏著劑層之表面相互接觸後不會增加新的交聯。此處，就能夠高速塗佈、對環境友好、溶劑所致之對基材或芯材之影響(膨潤、溶解)較少之方面而言，較佳為水分散型黏著劑，更佳為水分散型之丙烯酸系黏著劑。Furthermore, as the adhesive, any type of solvent-based adhesive or water-dispersed adhesive can be used. It is preferred that the adhesive composition is cross-linked by drying (evaporation of the solvent), and the cross-linking is completed quickly after drying. The coupler. The reason is that new cross-links will not be added after the surfaces of the adhesive layer come into contact with each other. Here, in terms of being capable of high-speed coating, being environmentally friendly, and having less influence (swelling, dissolution) on the base material or core material due to solvents, a water-dispersed adhesive is preferred, and a water-dispersed adhesive is more preferred.

Furthermore, typically, the adhesive layer is formed continuously, but is not limited to this form, and may be formed into a regular or random pattern such as dots or stripes. Furthermore, the end surface of the core material may be covered with the adhesive layer or not.

芯材之拉伸斷裂強度並無特別限定，可根據目的適當選擇，但就提高二次加工性之觀點而言，較佳為100 N/mm 2以上，更佳為200 N/mm 2以上，進而較佳為300 N/mm 2以上。 此處，所謂拉伸斷裂強度，指的是將芯材於25℃之溫度條件下，以拉伸速度300 mm/min實施拉伸試驗，將產生拉伸斷裂之時點之負載[N]換算成線狀黏著體之截面面積之每單位面積[mm 2]所得之值[N/mm 2]。針對芯材之拉伸速度300 mm/min之拉伸試驗可使用與樣品用接合體之拉伸試驗所使用之上述裝置相同者。 The tensile strength at break of the core material is not particularly limited and can be appropriately selected according to the purpose, but from the viewpoint of improving secondary processability, it is preferably 100 N/mm 2 or more, more preferably 200 N/mm 2 or more, and further preferably 300 N/mm 2 or more. Here, the tensile strength at break refers to the value [N/mm 2] obtained by converting the load [N] at the time of tensile fracture into the cross-sectional area per unit area [mm 2 ] of the linear adhesive body when the core material is subjected to a tensile test at a temperature of 25°C and a tensile speed of 300 mm/min. The tensile test of the core material at a tensile speed of 300 mm/min can be performed using the same apparatus as that used for the tensile test of the sample joint body.
芯材之截面之尺寸並無特別限定，可根據目的適當選擇，例如於為圓形之截面形狀之情形時，就操作性(彎曲性、斷裂難易度)之觀點而言，其直徑較佳為1 μm～2000 μm，更佳為10 μm～1000 μm，進而較佳為200 μm～600 μm。The cross-sectional size of the core material is not particularly limited and can be appropriately selected according to the purpose. For example, in the case of a circular cross-sectional shape, from the viewpoint of workability (bendability, ease of breakage), the diameter is preferably 1 μm to 2000 μm, more preferably 10 μm to 1000 μm, further preferably 200 μm to 600 μm.
黏著劑層之厚度並無特別限定，就黏著性之觀點而言，例如較佳為1 μm以上，更佳為3 μm以上。又，就厚度不均、乾燥性之觀點而言，例如較佳為200 μm以下，更佳為150 μm以下。進而，亦可藉由積層來對應於用途加厚。The thickness of the adhesive layer is not particularly limited. From the perspective of adhesiveness, it is preferably 1 μm or more, more preferably 3 μm or more. From the perspective of thickness unevenness and dryness, it is preferably 200 μm or less, more preferably 150 μm or less. Furthermore, it can be thickened according to the application by lamination.
線狀黏著體1尤佳為形成黏著劑層1b之黏著劑於常溫下具有黏著性，且可藉由黏著劑之表面與被黏著體之表面接觸時所產生之壓力將被黏著體貼附於其表面之感壓型黏著體。若為感壓型黏著體，則無需加熱，亦可應用於不耐受熱之被黏著體。The linear adhesive 1 is preferably such that the adhesive forming the adhesive layer 1b has adhesiveness at normal temperature, and can adhere the adherend to it by the pressure generated when the surface of the adhesive comes into contact with the surface of the adherend. Pressure-sensitive adhesive on the surface. If it is a pressure-sensitive adhesive, there is no need to heat it, and it can also be applied to adherends that cannot withstand heat.
如上所述，線狀黏著體1之形狀並無特別限定，線狀黏著體1之截面形狀中之長軸(通過截面之重心之軸中最長之軸)之長度相對於短軸(通過截面之重心之軸中最短之軸)之長度之比率(長軸/短軸)越大，線狀黏著體1成為越扁平之形狀。另一方面，該比率越小，線狀黏著體1之截面形狀越接近圓形，於截面之形狀為圓形之情形時，該比率成為作為最小值之1。於最小值1之情形時，亦包含如三角形、星形等特殊形狀。As described above, the shape of the linear adhesive 1 is not particularly limited. The greater the ratio (long axis/short axis) of the length of the major axis (the longest axis among the axes passing through the center of gravity of the cross section) to the length of the minor axis (the shortest axis among the axes passing through the center of gravity of the cross section) in the cross-sectional shape of the linear adhesive 1, the flatter the shape of the linear adhesive 1 becomes. On the other hand, the smaller the ratio, the closer the cross-sectional shape of the linear adhesive 1 becomes to a circle. When the cross-sectional shape is a circle, the ratio becomes 1, which is the minimum value. When the minimum value is 1, special shapes such as triangles and stars are also included.
(貼附線狀黏著體之形狀) 本發明之貼附方法中之貼附線狀黏著體之形狀並無特別限制，只要滿足上述1.0≦Q(0°)/Q(90°)＜1.1之關係即可。以下示出本發明之貼附方法中之貼附線狀黏著體之形狀之較佳例，但本發明並不限定於該等例。 (Shape of attached linear adhesive) The shape of the attached linear adhesive in the attachment method of the present invention is not particularly limited, as long as it satisfies the above relationship of 1.0≦Q(0°)/Q(90°)＜1.1. The following shows a preferred example of the shape of the attached linear adhesive in the attachment method of the present invention, but the present invention is not limited to such examples.
將本發明之貼附方法中之貼附線狀黏著體之形狀之較佳態樣示於圖2。作為此種例，可例舉(a)圓形、(b)螺旋圓形(3圈)及(c)螺旋圓形(5圈)。藉由將貼附線狀黏著體之形狀設為圓形或螺旋圓形，可使使用貼附裝置等時之貼附速度變快，故於產距時間之方面有利。FIG2 shows a preferred shape of the attached linear adhesive in the attachment method of the present invention. Examples of such shapes include (a) a circle, (b) a spiral circle (3 turns), and (c) a spiral circle (5 turns). By setting the shape of the attached linear adhesive to a circle or a spiral circle, the attachment speed when using an attachment device can be increased, which is advantageous in terms of production time.
此處，螺旋圓形之圈數係根據螺旋圓橫切連結螺旋圓之最外側之起點與重心之直線之次數來確定。例如，將自最外側出發之螺旋圓到達連結該起點與重心之直線處視作「1圈」，若繼而到達該直線，則成為「2圈」。下述螺旋四邊形亦可以相同之方式考慮。Here, the number of turns of the spiral circle is determined by the number of times the spiral circle crosses the straight line connecting the outermost starting point of the spiral circle and the center of gravity. For example, if the spiral circle starting from the outermost side reaches the straight line connecting the starting point and the center of gravity, it is considered "1 turn", and if it continues to reach the straight line, it becomes "2 turns". The following spiral quadrilateral can also be considered in the same way.
將本發明之貼附方法中之貼附線狀黏著體之形狀之較佳之其他態樣示於圖3。作為此種例，可例舉(d)四邊形、(e)具有一部分重複之部分之四邊形(帶重合之四邊形)、(f)螺旋四邊形(3圈)及(g)螺旋四邊形(5圈)。藉由將貼附線狀黏著體之形狀設為四邊形或螺旋四邊形，於描繪之重複精度之方面有利。Another preferred aspect of the shape of the attached linear adhesive body in the attaching method of the present invention is shown in FIG. 3 . Examples of this include (d) a quadrilateral, (e) a quadrilateral having a partially repeated part (a quadrilateral with overlapping), (f) a spiral quadrilateral (3 turns), and (g) a spiral quadrilateral (5 turns). By setting the shape of the attached linear adhesive body as a quadrilateral or a spiral quadrilateral, it is advantageous in terms of repeatability of drawing.
又，將與本發明之貼附方法中之貼附線狀黏著體之形狀不同之態樣示於圖4。作為此種例，可例舉(h)條紋(4條)及(i)波形(5山4谷)。In addition, FIG. 4 shows an aspect that is different from the shape of the attached linear adhesive body in the attaching method of the present invention. Examples of this include (h) stripes (4 strips) and (i) waveforms (5 hills and 4 valleys).
此種與本發明之貼附方法中之貼附線狀黏著體之形狀不同之形狀(h)及(i)係不滿足上述1.0≦Q(0°)/Q(90°)＜1.1之關係之典型例。基於此種形狀之線狀黏著體之貼附方法有根據剪切方向而黏著特性不同之虞，故不適合要求對所有剪切方向之外力均穩定之黏著特性的用途。The shapes (h) and (i) that are different from the shapes of the linear adhesives in the attaching method of the present invention are typical examples that do not satisfy the above relationship of 1.0≦Q(0°)/Q(90°)＜1.1. The attaching method of the linear adhesives with such shapes may have different adhesive properties depending on the shear direction, so it is not suitable for applications that require stable adhesive properties against external forces in all shear directions.
線狀黏著體之貼附方法是否相當於本發明之貼附方法可以貼附形狀之長徑比為標準進行判斷。長徑比定義為剪切強度成為最大之方向之線狀黏著體之長度b與和上述剪切強度成為最大之方向呈90°之方向之線狀黏著體之長度a之比(b/a)。Whether the method of attaching a linear adhesive is equivalent to the method of attaching of the present invention can be judged based on the aspect ratio of the attached shape. The aspect ratio is defined as the ratio of the length b of the linear adhesive in the direction where the shear strength is the largest to the length a of the linear adhesive in the direction at 90° to the direction where the shear strength is the largest (b/a).
例如，關於圖2(b)螺旋圓(3圈)，貼附形狀之長徑比可如圖5所示般求出。首先，描繪出與第1圈之螺旋圓之外圈相接之四邊形。對該四邊形之邊長進行比較，將較長者設為b1，將較短者設為a1。此時，b1為剪切強度成為最大之方向之長度，a1為與剪切強度成為最大之方向呈90°之方向之長度。 以相同方式描繪出與第2圈及第3圈之螺旋圓之外圈相接之四邊形，該四邊形之邊之長度成為b2及b3(剪切強度成為最大之方向之長度)、以及a2及a3(與剪切強度成為最大之方向呈90°之方向之長度)。 For example, regarding the spiral circle (3 turns) in Figure 2(b), the aspect ratio of the attached shape can be obtained as shown in Figure 5. First, draw a quadrilateral connected to the outer circle of the first spiral circle. Compare the side lengths of the quadrilateral, and set the longer one as b1 and the shorter one as a1. At this time, b1 is the length in the direction where the shear strength becomes the maximum, and a1 is the length in the direction 90° to the direction where the shear strength becomes the maximum. In the same way, draw a quadrilateral connected to the outer circle of the spiral circle of the second and third turns. The lengths of the sides of this quadrilateral are b2 and b3 (the length in the direction where the shear strength is maximum), and a2 and a3. (The length is 90° to the direction where the shear strength becomes maximum).
可基於以如上方式獲得之a1～a3及b1～b3，針對圖2(b)螺旋圓(3圈)，如下所述般求出貼附形狀之長徑比。 (貼附形狀之長徑比)＝(b1＋b2＋b3)/(a1＋a2＋a3) Based on a1 to a3 and b1 to b3 obtained in the above manner, the aspect ratio of the attached shape can be obtained as follows with respect to the spiral circle (3 turns) in Fig. 2(b). (Aspect ratio of attached shape)=(b1+b2+b3)/(a1+a2+a3)
同樣地，關於螺旋圓(n圈)之貼附形狀之長徑比亦可如下所述般求出。 (貼附形狀之長徑比)＝(b1＋b2＋…＋bn)/(a1＋a2＋…＋an) Similarly, the aspect ratio of the attached shape of the spiral circle (n turns) can be calculated as follows. (Aspect ratio of attached shape) = (b1 + b2 + ... + bn) / (a1 + a2 + ... + an)
又，例如針對圖4(i)波形(5山4谷)，貼附形狀之長徑比可如圖6所示般求出。於波形之情形時，對將波之振幅變成2倍所得之長度與波之週期之一半之長度進行比較，將較長者設為b，將較短者設為a。此時，b為剪切強度成為最大之方向之長度，a為與剪切強度成為最大之方向呈90°之方向之長度。於圖6中，使波之振幅變成2倍所得之長度成為b，波之週期之一半之長度成為a。For example, for the waveform (5 hills and 4 valleys) in Figure 4(i), the aspect ratio of the attached shape can be obtained as shown in Figure 6. In the case of a waveform, compare the length obtained by doubling the amplitude of the wave with the length of half the period of the wave, and let the longer one be b and the shorter one be a. At this time, b is the length in the direction where the shear strength becomes the maximum, and a is the length in the direction 90° to the direction where the shear strength becomes the maximum. In Figure 6, the length obtained by doubling the amplitude of the wave is b, and the length half the period of the wave is a.
可基於以如上方式獲得之a及b，針對圖4(i)波形(5山4谷)，如下所述般求出貼附形狀之長徑比。 (貼附形狀之長徑比)＝b/a Based on a and b obtained in the above manner, the aspect ratio of the attached shape can be obtained as follows for the waveform (5 hills and 4 valleys) in Fig. 4(i). (Aspect ratio of attached shape)=b/a
再者，根據波形之態樣，將波之振幅變成2倍所得之長度與波之週期之一半之長度均可成為a或b。Furthermore, depending on the shape of the waveform, the length obtained by doubling the amplitude of the wave and the length half the period of the wave can be either a or b.
於本發明中，貼附形狀之長徑比較佳為未達1.5，更佳為未達1.4，進而較佳為未達1.3時，有滿足上述1.0≦Q(0°)/Q(90°)＜1.1之關係之傾向。 又，由於處於bn≧an或b≧a之關係，故貼附形狀之長徑比之下限為1.0。 In the present invention, when the aspect ratio of the attached shape is preferably less than 1.5, more preferably less than 1.4, and further preferably less than 1.3, the above-mentioned 1.0≦Q(0°)/Q(90°) must be satisfied The tendency of the relationship is <1.1. In addition, since the relationship is bn≧an or b≧a, the upper limit of the aspect ratio of the attached shape is 1.0.
雖例示了單筆形狀作為本發明之貼附方法中之貼附線狀黏著體之形狀之一態樣，但業者明白只要滿足上述1.0≦Q(0°)/Q(90°)＜1.1之關係，則並不限定於單筆形狀。作為本發明之貼附方法中可採用之貼附線狀黏著體之形狀中並非單筆之形狀，例如可例舉雙重圓、三重圓等多重圓、雙重四邊、三重四邊等多重四邊。又，該等形狀中之貼附形狀之長徑比亦可依據上述方法求出。 但是，就提高作業性及二次加工性之觀點而言，於本發明之貼附方法中，較佳為藉由單筆形狀貼附線狀黏著體。 Although a single-stroke shape is exemplified as one of the shapes of the attached linear adhesive in the attachment method of the present invention, the industry understands that as long as the above relationship of 1.0≦Q(0°)/Q(90°)＜1.1 is satisfied, it is not limited to a single-stroke shape. The shapes of the attached linear adhesive that can be used in the attachment method of the present invention are not single-stroke shapes, for example, multiple circles such as double circles and triple circles, and multiple quadrilaterals such as double quadrilaterals and triple quadrilaterals. In addition, the aspect ratio of the attached shapes in these shapes can also be calculated according to the above method. However, from the perspective of improving workability and secondary processing, in the attachment method of the present invention, it is better to attach the linear adhesive by a single-stroke shape.
雖例示了單筆形狀作為本發明之貼附方法中之貼附線狀黏著體之形狀之一態樣，但只要滿足上述1.0≦Q(0°)/Q(90°)＜1.1之關係，則亦可使貼附之端部之終點之餘長如圖7所示般延伸。藉由使餘長延伸，二次加工時端部容易引出，從而可容易地進行二次加工。圖7(b')及(f')分別相當於針對圖2(b)及圖3(f)所示之線狀黏著體，使貼附之端部之終點之餘長延伸後之態樣。Although a single shape is illustrated as one of the shapes of the attached linear adhesive in the attachment method of the present invention, as long as the above relationship of 1.0≦Q(0°)/Q(90°)＜1.1 is satisfied, the excess length of the end point of the attached end can be extended as shown in FIG7. By extending the excess length, the end can be easily led out during secondary processing, thereby making it easy to perform secondary processing. FIG7(b') and (f') are equivalent to the state after the excess length of the end point of the attached end is extended for the linear adhesive shown in FIG2(b) and FIG3(f), respectively.
再者，於本發明之貼附方法中，較佳為藉由星形、長方形或三角形以外之形狀貼附線狀黏著體。Furthermore, in the attaching method of the present invention, it is preferred to attach the linear adhesive in a shape other than a star, rectangle or triangle.
(被黏著體) 可於本發明之貼附方法中使用之被黏著體並無特別限制，只要為可貼附上述線狀黏著體之範圍者即可。作為被黏著體，例如可例舉ABS樹脂、PC(聚碳酸酯)樹脂、丙烯酸系樹脂、金屬等。被黏著體之形狀亦並無特別限制。 (Adhered body) The adherend that can be used in the attachment method of the present invention is not particularly limited, as long as it is within the range where the above-mentioned linear adhesive can be attached. Examples of the adherend include ABS resin, PC (polycarbonate) resin, acrylic resin, metal, and the like. The shape of the adherend is not particularly limited.

The linear adhesive body is attached to the first adherend in the following shape. Here, the above-mentioned The shape is as follows: an ABS resin plate is placed on the linear adhesive body of the ABS resin (acrylonitrile-butadiene-styrene copolymerized synthetic resin) plate with the above-mentioned linear adhesive body attached, and the ABS resin plate is processed by processing The sample joint obtained by pressing the press at a pressure of 0.35 MPa for 10 seconds is subjected to a tensile test at a tensile speed of 300 mm/min at a temperature of 25°C and the load at which shear failure occurs [ N] is converted into the shear strength [N/mm 2 ] per unit area [mm 2 ] of the bonding area of the linear adhesive to the ABS resin plate. For the obtained shear strength, the above shear strength becomes the maximum direction. The shear strength Q (0°) and the shear strength Q (90°) in the direction 90° to the direction in which the shear strength becomes maximum satisfy the following relationship. 1.0≦Q(0°)/Q(90°)<1.1
上述式中，Q(0°)及Q(90°)之求出方法如上所述。Q(0°)/Q(90°)之較佳範圍、貼附線狀黏著體之形狀之較佳態樣亦如上所述。In the above formula, Q(0°) and Q(90°) are determined as described above. The preferred range of Q(0°)/Q(90°) and the preferred shape of the linear adhesive are also as described above.
本發明之貼附體因上述原因，可供給對所有剪切方向之外力均顯示出穩定之黏著特性且二次加工性優異之接合體。Due to the above reasons, the attachment of the present invention can provide a bonded body that exhibits stable adhesion properties against external forces in all shear directions and has excellent secondary processability.

＜接合體＞ 本發明之接合體係於上述貼附體中所含之線狀黏著體之上配置第2被黏著體，且將第1被黏著體與第2被黏著體接合而成。 又，本發明之接合體亦可為如於上述第2被黏著體之上進而貼附線狀黏著體，並於其上配置第3被黏著體之使3層以上之被黏著體接合而成者。於此種情形時，只要至少1組被黏著體之接合中之線狀黏著體之貼附方法依據本發明即可，不論其他被黏著體之接合之態樣如何，均可稱為本發明之接合體。 <Joint> The joined body of the present invention is formed by placing a second adherend on the linear adhesive contained in the above-mentioned adherend, and joining the first adherend and the second adherend. In addition, the joined body of the present invention may also be formed by joining three or more layers of adherends, such as further attaching a linear adhesive on the above-mentioned second adherend and placing a third adherend thereon. In this case, as long as the method of attaching the linear adhesive in at least one set of adherends is based on the present invention, it can be called the joined body of the present invention regardless of the manner of joining of other adherends.
本發明之接合體因上述原因，對所有剪切方向之外力均顯示出穩定之黏著特性，且二次加工性優異。Due to the above reasons, the bonded body of the present invention exhibits stable adhesion characteristics to external forces in all shear directions and has excellent secondary processability.
(第2被黏著體) 本發明之接合體中之第2被黏著體可使用作為上述被黏著體而例舉者，較佳態樣亦相同。第2被黏著體可與第1被黏著體相同，又，亦可不同。 (Second adherend) The second adherend in the joint of the present invention can be used as the above-mentioned adherend, and the preferred embodiment is the same. The second adherend can be the same as the first adherend, or different.
(接合體之製造方法) 本發明之接合體之製造方法並無特別限制，例如可例舉包括如下步驟之製造方法：於上述貼附體中所含之線狀黏著體之上配置第2被黏著體，並將第1被黏著體與上述第2被黏著體接合。 (Method for manufacturing joint body) The manufacturing method of the bonded body of the present invention is not particularly limited.

如以上所說明，於本說明書中揭示如下事項。 ＜1＞ 一種線狀黏著體之貼附方法，其包括藉由下述形狀將上述線狀黏著體貼附於被黏著體之步驟， 此處，上述形狀係如下形狀：針對在貼附有上述線狀黏著體之ABS樹脂(丙烯腈-丁二烯-苯乙烯共聚合合成樹脂)板之上述線狀黏著體之上進而配置ABS樹脂板，並利用加壓機於0.35 MPa之壓力下壓接10秒所得之樣品用接合體，於25℃之溫度條件下以拉伸速度300 mm/min實施拉伸試驗，將產生剪切破壞之時點之負載[N]換算成線狀黏著體對ABS樹脂板之接著面積之每單位面積[mm 2]而獲得剪切強度[N/mm 2]，針對所得之剪切強度，上述剪切強度成為最大之方向之剪切強度Q(0°)與和上述剪切強度成為最大之方向呈90°之方向之剪切強度Q(90°)滿足下述關係。 1.0≦Q(0°)/Q(90°)＜1.1 ＜2＞ 如＜1＞所記載之方法，其中上述線狀黏著體包含線狀之芯材、及被覆上述芯材之周圍之黏著劑層。 ＜3＞ 如＜2＞所記載之方法，其中上述芯材之拉伸斷裂強度為100 N/mm 2以上， 此處，上述拉伸斷裂強度係將上述芯材於25℃之溫度條件下，以拉伸速度300 mm/min實施拉伸試驗，將產生拉伸斷裂之時點之負載[N]換算成線狀黏著體之截面面積之每單位面積[mm 2]所得之值[N/mm 2]。 As explained above, the following matters are disclosed in this specification. <1> A method of attaching a linear adhesive body, which includes the step of attaching the linear adhesive body to an adherend in the following shape. Here, the above shape is the following shape: For when the above line is attached An ABS resin (acrylonitrile-butadiene-styrene copolymerized synthetic resin) plate is placed on the linear adhesive body, and the ABS resin plate is pressed under a pressure of 0.35 MPa using a press for 10 seconds. The sample joint body obtained in seconds was subjected to a tensile test at a tensile speed of 300 mm/min at a temperature of 25°C. The load [N] at which shear failure occurred was converted into a linear adhesive body against the ABS resin plate. The shear strength [N/mm 2 ] is obtained per unit area [mm 2 ] of the connecting area. For the obtained shear strength, the shear strength Q (0°) in the direction in which the above-mentioned shear strength becomes the maximum is equal to the above-mentioned shear strength. The shear strength Q (90°) in the direction in which the shear strength becomes maximum is 90° and satisfies the following relationship. 1.0≦Q(0°)/Q(90°)＜1.1 ＜2＞ The method as described in ＜1＞, wherein the linear adhesive body includes a linear core material and an adhesive covering the periphery of the core material layer. <3> The method according to <2>, wherein the tensile breaking strength of the core material is 100 N/mm 2 or more.
