関するものである。[Structure of the Invention] (Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems. SMC's manufacturing method, which is characterized by impregnating reinforcing fibers with a resin composition containing a thickener and then curing, and providing a coating that dissolves or peels off with a thermosetting resin. A thickener for SMC, characterized by a thickener for SMC, and a thickener for SMC, characterized by covering the thickener with a material that is dissolved or peeled off by a liquid thermosetting resin in which the thickener is blended. The present invention relates to a method for treating chemicals.
次に本発明を更に具体的に説明する。Next, the present invention will be explained in more detail.
液状の熱硬化性樹脂としては、不飽和ポリエステル樹脂
、エポキシ樹脂等が使用できるが、不飽和ポリエステル
樹脂を用いるのか実際的である。As the liquid thermosetting resin, unsaturated polyester resin, epoxy resin, etc. can be used, but it is practical to use unsaturated polyester resin.

It is appropriate to use one with 5 tiles, preferably 0.4 to 5 tiles.
本発明においては増粘剤として、その表面を、以下述べ
るような特定の材料（以下本材料という）で被覆したも
のを使用する。In the present invention, the thickener used is one whose surface is coated with a specific material (hereinafter referred to as the present material) as described below.

ＭＣの性質に悪影響を与える恐れがない。As this material, metal soaps, especially fatty acid salts of alkaline earth metals used as internal mold release agents for SMC, such as zinc stearate, are suitable, and their effects are good.
There is no risk of adversely affecting the properties of MC.

テル樹脂のような液状の熱硬化性樹脂中に配合すると、
被覆は樹脂によって緩やかに溶解、除去され、被覆と増
粘剤粒子との結合力が低下して被覆が剥離、脱落する。When a thickener coated with such a metal soap is blended into a liquid thermosetting resin such as an unsaturated polyester resin,
The coating is slowly dissolved and removed by the resin, and the binding force between the coating and the thickener particles decreases, causing the coating to peel off and fall off.

フは大きく、本樹脂組成物を補強繊維に含浸させる工程
中の組成物の粘度の変化は僅かであり、作業条件は実質
的に一定に保たれるため、ＳＭＣの品質にバラツキが生
ずることがない。Immediately after preparing the resin composition, the coating prevents contact between the resin and the thickener, and no thickening occurs at all. Thereafter, the viscosity increases as the coating dissolves, peels, and falls off.Since the coating melts and removes, peels, and falls off very slowly, the initial viscosity increase rate of the resin composition is extremely low.
The pot life of the resin composition (hereinafter referred to as the present composition) containing the thickener coated with the present material (hereinafter referred to as the present thickener) is long, and the composition during the process of impregnating reinforcing fibers with the present resin composition is Since the viscosity of the product changes only slightly and the working conditions remain substantially constant, there is no variation in the quality of the SMC.
又被覆の溶解除去、剥離脱落がある程度進行すると、樹
脂と増粘剤の接触により樹脂組成物の粘度は急激に上昇
する。Further, when the dissolution and removal of the coating progresses to a certain extent, the viscosity of the resin composition rapidly increases due to contact between the resin and the thickener.

といつは、従来のＳＭＣに比し、粘度を所定値迄高める
のに必要な養生期間は若干大となるが、製造工程に格段

．． It is appropriate to spread the thickener for 2 to 3 times, but it is not necessary to cover the entire surface of the thickener, and the thickness of the coating does not need to be uniform.
