In the manufacturing method of the present embodiment, the
又,本實施形態之製造方法之中,因為將複數之突部11成形為剖面係三角形,所以可於將樹脂成型品1使用作為廚房操作台12時,抑制其與高溫狀態之調理容器之接觸面積。因此,調理容器的痕跡不易附著在廚房操作台12的上表面。
Moreover, in the manufacturing method of this embodiment, since the plurality of
又,本實施形態之製造方法之中,因為複數之突部11突出50μm以上,所以即使將高溫狀態之調理容器承載在複數之突部11之上,亦可將從調理容器至基底部10之距離確保為一定程度,且不易產生基底部10因熱而變色等不良狀況。
Furthermore, in the manufacturing method of this embodiment, since the plurality of
又,本實施形態之製造方法之中,複數之突部11係以50μm以上、400μm以下之尺寸而些微突出,因此鄰接之突部11間的部分101不易藏污納垢。
Furthermore, in the manufacturing method of this embodiment, the
又,樹脂成型品1之中,因為從基底部10的表面100突出有複數之突部11,所以當光照射時則容易在樹脂成型品1的表面產生陰影,而容易有效顯示花紋。

本實施形態的花紋硬化步驟,利用加熱模具2的下模2a,而使已注入至複數之凹陷3之花紋形成用樹脂組成物4硬化。將下模2a加熱至用以使花紋形成用樹脂組成物4進行硬化反應之溫度(例如70℃)。
In the pattern hardening step of the present embodiment, the
本實施形態的基底形成步驟,包含:冷卻步驟,將模具2的下模2a冷卻至基底用樹脂組成物5的注入溫度(意即基底用樹脂組成物5不進行硬化反應之溫度)為止。此冷卻步驟之後,將基底用樹脂組成物5往模具2(2a、2b)注入成覆蓋成形面20。於注入基底用樹脂組成物5之後,加熱模具2(2a、2b),藉以使基底用樹脂組成物5硬化。

The
此外,花紋形成用樹脂組成物4之中,只要將顆粒狀的花紋材以外的著色劑的添加量以花紋形成用樹脂組成物4的整體的固形量換算係0.2%以下,則亦可具有與基底用樹脂組成物5的著色劑係不同之著色劑。此係因為於花紋形成用樹脂組成物4的著色劑的總量少之情形下,花紋形成用樹脂組成物4的每一製造批量的色偏顯眼,因此添加少量的色劑(toner)來抑制此色偏。

The manufacturing method of this embodiment uses the above-mentioned pattern forming
本實施形態之製造方法之中,花紋形成用樹脂組成物4含有顆粒狀的花紋材作為著色劑,因此於注入基底用樹脂組成物5時,顆粒狀的花紋材不易化學性溶解。又,顆粒狀的花紋材因物理性卡絆在粗糙面的成形面20而不易流出。再者,即使於顆粒狀的花紋材的一部分流出之情形下,亦因為顆粒狀的花紋材不易溶解,所以相較於顏料或染料流出之情形而言,可抑制花紋形成用樹脂組成物4的顏色廣範圍流出。

8.總結 8. Summary
如以上說明之實施形態1~6及其變形例之製造方法,第一態樣之製造方法具備下述構成。
As in the manufacturing methods of
亦即,第一態樣之製造方法,係將在成形面(20)具有複數之凹陷(3)之模具(2)加以使用來製造樹脂成型品(1)之方法。此製造方法包括花紋注入步驟、花紋硬化步驟、及基底形成步驟。花紋注入步驟,將花紋形成用樹脂組成物(4)注入至複數之凹陷(3)。花紋硬化步驟,使已注入至複數之凹陷(3)之花紋形成用樹脂組成物(4)硬化。基底形成步驟,將組成係與花紋形成用樹脂組成物(4)不同之基底用樹脂組成物(5),往模具(2)注入成覆蓋成形面(20),並使其硬化。 That is, the manufacturing method of the first aspect is a method of manufacturing a resin molded product (1) by using a mold (2) having a plurality of depressions (3) on the molding surface (20). The manufacturing method includes a pattern injection step, a pattern hardening step, and a base forming step. In the pattern injection step, the resin composition (4) for pattern formation is injected into the plurality of depressions (3). The pattern hardening step hardens the pattern-forming resin composition (4) that has been injected into the plurality of depressions (3). In the base forming step, a base resin composition (5) having a different composition from the pattern forming resin composition (4) is injected into the mold (2) to cover the molding surface (20) and cured.
如同上述構成,第一態樣之製造方法,係於各凹陷(3)內配置有花紋形成用樹脂組成物(4)之狀態下,注入基底用樹脂組成物(5)。因此,第一態樣之製造方法,可抑制因注入基底用樹脂組成物(5)而導致花紋形成用樹脂組成物(4)的位置錯移,而使花紋紊亂。藉此,第一態樣之製造方法,容易將期望之花紋顯示在樹脂成型品(1)的表面。 As with the above configuration, the manufacturing method of the first aspect is to inject the resin composition (5) for the base in a state where the resin composition (4) for pattern formation is arranged in each recess (3). Therefore, the manufacturing method of the first aspect can prevent the resin composition for pattern formation (4) from shifting due to the injection of the resin composition (5) for the base, causing the pattern to be disordered. Thereby, the manufacturing method of the first aspect can easily display the desired pattern on the surface of the resin molded product (1).
又,如同上述實施形態1~6及其變形例之製造方法,第二態樣之製造方法,於第一態樣之製造方法的構成以外,還另具備下述構成。

In the pattern injection step, the resin composition (4) for forming a pattern is injected into a part of the longitudinal direction of each of the depressions (3) for the plurality of depressions (3). In the substrate forming step, the resin composition (5) for the substrate is injected into the mold (2) to cover the molding surface (20), and the resin composition (5) for the substrate is injected into each of the depressions (3). The remaining part of the recess (3) other than the aforementioned part in the longitudinal direction.
利用具備上述構成之第三態樣之製造方法製造之樹脂成型品(1)之中,可將顯示在由複數之凹陷(3)形成之複數之突部(11)之花紋,利用注入有花紋形成用樹脂組成物(4)之部分與未注入之部分來改變。藉此,利用第三態樣之製造方法製造之樹脂成型品(1)之中,可顯示不均勻的花紋而將更自然的花紋模樣顯示在表面。 In the resin molded product (1) manufactured by the third aspect of the manufacturing method having the above-mentioned structure, the pattern displayed on the plural protrusions (11) formed by the plural recesses (3) can be injected with the pattern The part of the resin composition (4) used for formation and the part not injected are changed. Thereby, in the resin molded product (1) manufactured by the manufacturing method of the third aspect, uneven patterns can be displayed and a more natural pattern can be displayed on the surface.
又,如同上述實施形態1~6及其變形例之製造方法,第四態樣之製造方法,於第一至第三態樣中任一製造方法的構成以外,更具備下述構成。

In the pattern hardening step, the mold (2) is heated to harden the pattern-forming resin composition (4) that has been injected into the plurality of depressions (3). In the base forming step, after cooling the mold (2) to the injection temperature of the base resin composition (5), the base resin composition (5) is injected.
具備上述構成之第四態樣之製造方法,可將含有硬化劑之花紋形成用樹脂組成物(4)加熱而使其硬化,藉以防止:於花紋形成用樹脂組成物(4)的硬化反應 不充份之狀態下,注入基底用樹脂組成物(5)。藉此,利用第四態樣之製造方法製造之樹脂成型品(1),可抑制花紋形成用樹脂組成物(4)的花紋擴散至意外的部分。又,第四態樣之製造方法之中,因為基底形成步驟包含冷卻步驟,所以可防止基底用樹脂組成物(5)注入至高溫狀態之模具(2),並可防止將基底用樹脂組成物(5)注入後即刻引起硬化反應。 The manufacturing method of the fourth aspect having the above-mentioned structure can heat and harden the pattern-forming resin composition (4) containing a hardener, thereby preventing: a hardening reaction in the pattern-forming resin composition (4) In an inadequate state, the resin composition (5) for the substrate is injected. Thereby, the resin molded article (1) manufactured by the manufacturing method of the fourth aspect can prevent the pattern of the resin composition (4) for pattern formation from spreading to unexpected parts. Furthermore, in the manufacturing method of the fourth aspect, since the substrate forming step includes a cooling step, the resin composition (5) for the substrate can be prevented from being injected into the mold (2) in a high temperature state, and the resin composition for the substrate can be prevented from being injected into the mold (2). (5) The hardening reaction is caused immediately after injection.
