本発明は、合成樹脂成品の表面に粒状物の付着ζ７よる
疎面を形成する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for forming a rough surface on the surface of a synthetic resin product by adhering particulate matter ζ7.
［従来の技術］

状物を付着させる手段が一般的に知られている。[Prior Art] Conventionally, methods for forming a rough surface by adhering particulate matter to the surface of a synthetic resin product include spraying a mixture of particulate matter and adhesive onto the surface of a so-called finished product that has been molded. Generally, a method is known in which adhesive is applied to the surface of a finished product in advance and granules are adhered thereon.
［発明が解決しようとする課題］
上記前者の吹きつけによる疎面形成方法は、粒状物が多

、従って、例えばこの成品を床材などの用途に使用し、
上記凹凸を歩行時の滑り止めとして機能させたいような
場合、引掛り作用が殆んどないため、上記用途には使用
することは不可能である。[Problems to be Solved by the Invention] In the former method of forming a rough surface by spraying, since granules are mixed with a large amount of adhesive, the rough surface formed on the surface of the product is not a rough surface. However, the adhesive builds up thickly and creates a gradual drop-like unevenness with almost no drop.Therefore, if this product is used for flooring, etc., for example,
If the unevenness is desired to function as an anti-slip surface when walking, it is impossible to use it for the above purpose because there is almost no catching effect.
一方、上記後者の疎面形成方法は、成品表面に塗着した

う問題は避は難く、要するに従来方法により表面に粒状
物の付着により疎面を形成した合成樹脂成品は、疎面に
直接摺擦圧が作用される用途には、その使用に困難性が
ある。On the other hand, the latter method of forming a rough surface involves attaching particulate matter to the adhesive applied to the surface of the product, so it has a non-slip function when walking, but since it is a simple adhesive, it is easy to get caught by feet. It is unavoidable that particulate matter tends to separate from the surface of the product, and in short, synthetic resin products that have a rough surface formed by adhesion of particulate matter to the surface by conventional methods are subjected to direct rubbing pressure on the rough surface. There are difficulties in its use.
そこで本発明は、液状合成樹脂の流し込み成形過程を有

を可能とした合成樹脂成品の提供を目的とするものであ
る。Therefore, the present invention effectively utilizes the casting process of liquid synthetic resin to strengthen the adhesion of granules to the surface of the product, and to effectively maintain the amount of protrusion of the granules. The object of the present invention is to provide a synthetic resin product that can be used in applications where rubbing pressure is applied.

を要旨とするものである。[Means for solving the problem] The present invention for achieving the above object provides a method for manufacturing a synthetic resin product molded by pouring a liquid synthetic resin, in which at least the surface of the poured liquid synthetic resin is gelled. In this state, a resin liquid is secondarily applied to the surface,
The gist of this method is to sprinkle particulate matter onto the gelled surface from above.

An enlarged cross section is shown.

に付着されるものである。In Fig. 4, A is a mold with a horizontal molding surface on the upper surface, glass fiber 1 is laid on the molding surface of mold A, and thermosetting liquid synthetic resin 2 is poured onto it to the desired thickness. ,
The upper surface is made flat by rolling a defoaming roller (not shown), and air bubbles interposed between the glass fibers 1 are removed to allow the synthetic resin 2 to permeate into the glass fibers 1. The above process is a general method for molding FRP products. Therefore, in the present invention, at least the surface (the smoothed surface) of the liquid synthetic resin 2 poured into the mold A is in a gelled state, and then a synthetic resin liquid 3 is secondarily applied to the surface. Irregularly shaped granules 4 (silica sand) having a particle size of approximately 0.3 to 1.0 mm are uniformly sprinkled onto the coating surface. The scattered particulate matter 4 is attached to the gelled surface without settling while expelling the resin liquid 3 by its mass, and the lower periphery of the particulate matter is surrounded by the resin liquid 3 that has flowed back due to the above-mentioned expulsion.
It is attached to.

The lower periphery is then attached to the applied resin liquid, and due to the strong bonding relationship after curing, the granules will not separate from the surface of the product even if a rubbing pressure is applied directly to the granules.

It can be used for purposes such as, and its rough surface can be effectively used as a bow hook to prevent slipping when walking.

有するものである。Furthermore, since the tips of the granules constituting the above-mentioned sparse surface are exposed without being hidden by the resin, the biting properties with the sole of the shoe are improved, and the anti-slip effect of the layer is exhibited. It has excellent features that cannot be expected with conventional methods of forming a rough surface, such as by spraying particles or simply adhering them to the adhesive surface.
