Abstract

The present invention makes it possible to adequately bond one resin molding with another molding even when, for example, the melting point of the resin of the one molding (resin molding) is lower than the molding temperature of the other molding. This grooved resin molding comprises an inorganic filler (11) and is obtained by forming multiple microgrooves (12) in which said inorganic filler (11) is exposed on the surface (10a) of said resin molding such that the ratio (W13:W12) of the width of the ridges (13), which are located between the microgrooves (12), to the width of the microgrooves (12) on the surface (10a) is 1: 1.5 - 5. The composite molding (1) is obtained by using the surface (10a) of such a grooved resin molding as the contact surface and disposing the other molding (20) adjacent thereto.

(minute grooves)
Minute grooves 12 is formed multiple at the surface 10a of resin forming product 10, and inorganic filler 11 is from this minute grooves 12 Sidewall (side) 12a comes out.This minute grooves 12 is by the part removal by the resin of composition resin forming product 10 Formed, like this by the part removal of resin such that it is able to make inorganic filler 11 with from the sidewall 12a of this minute grooves 12 Prominent state comes out.
It addition, as in figure 2 it is shown, at the resin forming product 10 making this trough of belt to have the face (surface 10a) of minute grooves 12 be When contact surface is integrated with another formed products 20 and manufactures composite formed article 1, this composite formed article 1 does not exposes inorganic filler 11.In this manual, even if in the case of composite formed article 1 does not exposes inorganic filler 11, if be certainly combined into Expose inorganic filler 11 from minute grooves 12 under the state that shape product 1 eliminate another formed products 20, be then also considered as " inorganic fill Agent 11 is exposed to minute grooves 12 ".
The preferably length direction (direction towards depth side in the sectional view of Fig. 1) of minute grooves 12 and inorganic fill The length direction of agent 11 is different.When the length direction of groove 12 is identical with the length direction of inorganic filler 11, it is possible to cannot It is being removed thus the concavo-convex projection 13 that formed because of the irradiated site of such as laser and non-irradiated position and a part for resin Between suitably set up inorganic filler 11.It is thus possible to inorganic filler 11 easily comes off from the resin forming product 10 of trough of belt, Resin forming product 10 and the anchorage effect of another formed products 20 destruction of suppression trough of belt cannot be played fully.Thus, it is preferable to It is as shown in the cross section of fig. 1 like that in the way of the length direction of minute grooves 12 is different from the length direction of inorganic filler 11 Resin is carried out laser irradiation etc. thus forms minute grooves 12.
It addition, the resin forming product at the trough of belt being formed with minute grooves (is referred to as " resin an one-tenth for convenience of description Shape product 50 ") be formed with this minute grooves (being referred to as " minute grooves 51 " for convenience of description) another formed products of face welding (in order to Be easy to explanation and be referred to as " another formed products 60 ") and make them integrated, thus manufacture composite formed article (for convenience of description and It is referred to as " composite formed article 70 ").Now, as the resin for constituting a resin forming product 50, sometimes use fusing point less than structure Become the fusing point of the material such as resin of another formed products 60, more specifically less than the resin of forming temperature of this another formed products 60 Material.In this case, make another formed products 60 melt and be filled with (shaping) in a resin forming product of trough of belt When 50, there is such a case that this resin forming product 50 melts because of higher forming temperature, be formed at this ester moulding The wall of the minute grooves 51 on the surface of product 50 collapses, is flushed away and damaged.Even if if it does, it is micro-then to make inorganic filler be exposed to this Sulculus 51, also due to cannot in the fused mass constituting the material of another formed products 60 cannot enter sufficiently into this minute grooves 51 Obtain the anchoring effect obtained by inorganic filler fully.
Therefore, in the present embodiment, for being formed at the minute grooves 12 of the resin forming product 10 of trough of belt, by the tree of trough of belt The width W of the minute grooves 12 of the surface 10a of resin-formed product 1012Control at preset range.Specifically, to be positioned at multiple minute grooves The width W of the projection 13 between 1213Width W with this minute grooves 1212Ratio (W13: W12) it is that the mode of 1:1.5～5 makes small The groove width of groove 12 is wider.
Here, width W12, width W13Refer to the width on the surface 10a of the resin forming product 10 of trough of belt, in Fig. 1 Dotted line X shown in, width (groove width) W of minute grooves 1212Refer to the peristome of this groove 12 and the surface (surface 10a) of protruding 13 The width in the groove portion on extended line (same level).
(A) of Fig. 3 represents that surface 10a is formed with the ultramicroscope photograph of the resin forming product 10 of the trough of belt of minute grooves 12 Sheet.As shown in (A) of this Fig. 3, in the resin forming product 10 of trough of belt, the width (groove width) making minute grooves 12 is wider, with W13: W12Represented ratio is calculated as 1:1.5～5.In the resin forming product 10 of trough of belt, the groove width making minute grooves 12 like this is wider, Even if thus less than the forming temperature of another formed products 20 or constituting the fusing point of material of another formed products 20 at the fusing point of resin In the case of, it is also possible to form the sufficient space making the material of another formed products 20 of composition flow into.Thereby, it is possible to make composition another The material of one formed products 20 is melted and reliably flow into this minute grooves 12 before being landfilled in the minute grooves 12 of resin forming product 10, The anchoring effect obtained by the inorganic filler 11 exposed from minute grooves 12 can be played, and the most closely sealed (joint) is another One formed products 20.
Enumerate concrete example, at the surface 10a of resin forming product 10, each to minute grooves 12 and projection 13 one (is saved as 1 group Away from), when this 1 pitch is 200 μm, for instance, it is possible to make the width W of protruding 1313It is 80 μm, makes the width W of minute grooves 1212For 120 μm (wherein, in this case, W13: W12=1:1.5.).Further, in the case of the pitch of 200 μm, for instance, it is possible to make The width W of protruding 1313It is 33.3 μm, makes the width W of minute grooves 1212It is 166.7 μm (wherein, in this case, about W13: W12=1:5.).
It addition, when 1 pitch of minute grooves 12 and protruding 13 is 300 μm, for instance, it is possible to make the width W of protruding 1313For 120 μm, make the width W of minute grooves 1212It is that 180 μm are (wherein, in this case, for W13: W12=1:1.5.).Further, at 300 μ In the case of the pitch of m, it is possible to make the width W of protruding 1313It is 50 μm, makes the width W of minute grooves 1212It is that 250 μm (wherein, exist In the case of Gai, for W13: W12=1:5.).
Wherein, described concrete example is to illustrate after all, is not limited to this, as long as W13: W12The model of=1:1.5～5 Enclose, then can be according to by minute grooves 12 and the suitably sized decision of protruding 13 pitches formed.But, if it is considered that preferably Obtain anchoring effect, the most preferably minute grooves 12 and protruding 13 each width as the pitch of 1 group be more than 100 μm and 500 below μ, more than more preferably 200 μm and below 300 μm.When the width of pitch is narrow, it is possible to inorganic filler 11 is not Can come out from the side of minute grooves 12, it is impossible to preferably obtain anchoring effect based on inorganic filler 11.The width of pitch When spending width, possible inorganic filler 11 easily comes off from the resin forming product 10 of trough of belt, and inorganic filler 11 cannot be fully Play resin forming product 10 and the anchorage effect of another formed products 20 destruction of suppression trough of belt.
The width W of minute grooves 12 of surface 10a for the resin forming product 10 of trough of belt12, as the width W of minute grooves 1212 The not enough width W of protruding 13131.5 times time, when another formed products 20 of welding, the resin forming product 10 of trough of belt melts, and is formed at The wall of the minute grooves 12 of this resin forming product 10 collapses and breakage occurs.On the other hand, as the width W of minute grooves 1212Exceed convex Play the width W of 13135 times time, it is possible to anchorage effect based on inorganic filler 11 cannot be played fully, at combined shaping When product 1 have external force, another formed products 20 can destroy.
It addition, for the width W of minute grooves 1212, to obtain with " W13: W12Ratio represented by " is calculated as the width of 1:2～4 Degree W12Mode to arrange minute grooves 12 be preferred.Thereby, it is possible to more effectively make the fused mass of another formed products 20 of composition Flow into the minute grooves 12 of the resin forming product 10 of trough of belt, it is possible to improve anchoring effect further and make the tree that bond strength is higher Resin-formed product 10.
Here, minute grooves 12 both can be formed at the surface 10a of resin forming product 10 by the striated shown in (A) in Fig. 3, And can also be as shown in (B) of Fig. 3, minute grooves 12 is formed at the surface of resin forming product 10 in the clathrate intersected 10a.Minute grooves 12 is formed as cancellate in the case of, it is also possible to be formed as length direction and the inorganic fill of minute grooves 12 The oblique clathrate that the length direction of agent 11 is different.As shown in (B) of Fig. 3, minute grooves 12 is formed as clathrate such that it is able to more The smelt flow reliably making the material of another formed products 20 of composition enters minute grooves 12.
Minute grooves 12 is formed as cancellate in the case of, for the width W of the minute grooves 12 of surface 10a12And projection The width W of 1313, the length direction (the x-axis direction in such as Fig. 3) the side along the minute grooves 12 forming lattice shape is carried out As long as this minute grooves 12 and protruding width both 13 meet W during observation13: W12The relation of=1:1.5～5.Further, The opposing party along minute grooves 12 length direction (the y-axis direction in such as Fig. 3) if this minute grooves 12 He when observing Protruding width both 13 meets W13: W12The relation of=1:1.5～5.
It addition, when like this minute grooves 12 being formed as clathrate, on the length direction (x-axis) of a side of minute grooves 12 Small with on the length direction (y-axis) of the opposing party of minute grooves 12 of width and the ratio of the width of protruding 13 of minute grooves 12 As long as the width of groove 12 is satisfied by W with the ratio of the width of protruding 1313: W12The relation of=1:1.5～5, both can be phase Same ratio, it is also possible to be different ratios.
Preferably degree of depth D of minute grooves 12 is length (that is, the width of minute grooves 12 on the short side direction of this minute grooves 12 Degree W12) more than 1/2.Width W when degree of depth D deficiency minute grooves 12121/2 time, formed engaging with another formed products 20 During composite formed article 1, may fill being exposed between the inorganic filler 11 of minute grooves 12 and another formed products 20 generation The anchoring effect divided, and the resin forming product 10 of trough of belt cannot be close to securely with another formed products 20.
