3 cannot be formed, and this thickly coated pattern part 1
When a liquid polyurethane material was poured onto the upper surface 5 of the base body 3 and cured by heating, bubbles were likely to occur in the transparent polyurethane layer 7 near the patterned portion 13. This generation of bubbles can be solved by setting the heating temperature to 50°C or less and curing time to several hours, but this is undesirable from the viewpoint of productivity. , In order to solve the L record reference point,
As a result of our earnest efforts in development, we came up with a method for manufacturing a mounting S member with the following configuration.

徴とする。A edging protrusion for forming a pattern is formed on the upper surface of a base made of synthetic resin, and a colored liquid polyurethane material is poured inside the edging protrusion and hardened to form a pattern having a positive meniscus on the upper surface of the base. Subsequently, a transparent liquid polyurethane material is poured over the entire upper surface of the base body on which the patterned portion is formed and cured, thereby forming a transparent polyurethane layer having a positive meniscus.

Do this for 0 to 30 minutes. When the temperature exceeds 100℃, the base material becomes PVC.
In such cases, undesirable softening and deformation occur, and a high rate of urethane curing reaction is not induced at temperatures below 60°C.

ことがほとんどない。(3) The transparent polyurethane layer 7 is made of the uncolored liquid polyurethane material used in (2) above, and is bottled over the entire upper surface of the base body on which the patterned portion 13 obtained in (2) above is formed. Form by doing. At this time,
Transparent polyurethane layer 7 formed on the entire top surface of the base body
has a positive meniscus. Further, the heat curing method for this transparent polyurethane layer 7 is carried out in the same manner as in the case of the above-mentioned pattern portion 13. The pattern is formed by pouring a colored liquid polyurethane material into the inside of the edging protrusion for pattern fabric formation and curing it, so the pattern has a positive meniscus and a transparent polyurethane layer covering the pattern. Coupled with the fact that it has a positive meniscus and exhibits a lens effect, it is possible to form a highly designed pattern with a three-dimensional effect. In addition, there is no need to form the pattern with solvent-based paint, and a transparent urethane layer is formed on the urethane layer (pattern) that does not contain solvent or water. There are almost no bubbles in the layer.
なお、泡の発生原因は、水分とインシアネートとの反応
によるＣ０２の発生、及び残留溶剤の気化によるものと
推定される。Note that the cause of the bubble generation is estimated to be the generation of CO2 due to the reaction between water and incyanate, and the vaporization of the residual solvent.
