<Industrial Application Fields> This invention relates to decorative and protective moldings in which the upper surface of a band-shaped base made of synthetic resin is covered with a transparent synthetic resin layer with a positive meniscus, particularly for side moldings, bumper moldings, etc. of automobiles. It is suitable for rotuka malls, interior decoration strips, etc. <Prior art> The above-mentioned type of decorative and protective molding (hereinafter referred to as "mall") is, for example, as shown in Fig. 1, which is a band-shaped synthetic resin strip with edge-shaped edges on both sides. It is manufactured by a method (so-called potting) in which a transparent synthetic resin layer 2 having a positive meniscus is formed by pouring a liquid transparent resin material of an appropriate viscosity onto the upper surface 1a of the base body 1 and curing it (so-called potting). 58-221741, etc.). According to this publication, polyurethane, which is a reaction product of a polyether polyol component (polypropylene glycol) and an aliphatic diisocyanate, is used as the material for the transparent synthetic resin layer 2 from the viewpoint of the wear resistance and impact resistance of the molding. Cured polyurethane products, which are reaction products of a mixture of polyester glycol and low to medium molecular weight polypropylene triol and an aliphatic diisocyanate-polypropylene triol adduct, are useful from the viewpoint of flexibility and the like. It is stated that there is. In the illustrated example, 3 is double-sided adhesive tape, and 4 is release paper. <Problems to be Solved by the Invention> However, as a result of prototyping the molding in which a transparent synthetic resin layer is formed using each of the above-mentioned cured polyurethane products, the inventors of the present invention have discovered that the following problems exist. Ta. (a) If the transparent synthetic resin layer is made of cured polyurethane, which is a reaction product of a polyether polyol component and an aliphatic diisocyanate component, when installing side moldings etc. It is necessary to perform bending according to the curvature, but at that time, cracks occur in the synthetic resin layer or the synthetic resin layer easily peels off from the base body. (b) If the transparent synthetic resin layer is a cured polyurethane product that is a reaction product of a mixture of polyester glycol and low to medium molecular weight polypropylene triol and an aliphatic diisocyanate-polypropylene triol adduct, the above problem can be solved. Although this problem can be solved to some extent, it is difficult to obtain a synthetic resin layer with medium transparency because the polyol component is composed of other components with different molecular weights. Therefore, it is not suitable for cases where it is desired to emphasize the lens effect of the synthetic resin layer. <Means for Solving the Problems> In the molding of the present invention, the upper surface of a band-shaped base made of synthetic resin is covered with a transparent synthetic resin layer having a positive meniscus, and the transparent synthetic resin layer is made of polyether. In those formed of a cured polyurethane product that is a reaction product of a polyol component and an aliphatic polyisocyanate component, a tetraol with an average molecular weight of about 1100 or less, which is an alkylene oxide polyadduct of ethylene diamine, is used as the polyether polyol component. By using this, the above problems can be solved. Each configuration of the above means will be explained in detail below (see FIG. 1). (1) The base body 1 is made of acrylonitrile butadiene styrene terpolymer (ABS), polyvinyl chloride (PVC), nylon (polyamide),
Heat resistance of polycarbonate, acrylonitrile styrene copolymer (AS), ionomer, etc.
Made of synthetic resin material with excellent impact resistance, molded by extrusion or injection. (2) The transparent synthetic resin layer 2 is formed by potting the polyurethane material, which has been sufficiently degassed under reduced pressure, on the upper surface of the base body 1.
At this time, a heavy metal compound-based or amine-based catalyst that is commonly used for curing polyurethane is added to the polyurethane material. Furthermore, from the standpoint of long-term quality stabilization of polyurethane, antioxidants,
It is also possible to add an ultraviolet absorber or a surfactant from the viewpoint of improving leveling properties, shortening defoaming time, etc. As a matter of course,
Use these agents that do not reduce the transparency of the cured polyurethane product. Further, the average molecular weight of the above-mentioned tetraol, which is an alkylene oxide polyadduct of ethylene diamine, is set to be 1100 or less, but is preferably 250 to 500. If it exceeds 1100, "stickiness" will occur on the surface of the transparent synthetic resin layer, which is not desirable. Also, 250-500
In between, the cured polyurethane develops thermoplastic properties (softens upon heating), making the molding easier to bend. The above alkylene oxide is
Usually propylene oxide is used, but ethylene oxide or 1,2-butylene oxide may also be used. The above-mentioned aliphatic isocyanates include not only the original aliphatic but also alicyclic ones, such as hexamethylene diisocyanate (HMDI), xylene diisocyanate (XDI), hydrogenated xylene diisocyanate (hydrogenated XDI), and 4,4'-methylene bis Examples include non-yellowing ones such as dicyclohexyl diisocyanate (H12MDI), methylcyclohexyl diisocyanate (hydrogenated TDI), and isophorone diisocyanate (IPDI), but from the viewpoint of handling, these are usually polyols to which a triol or the like has been added. It is used as an adduct or a polymer with low volatility. The blending ratio of the polyol component and isocyanate component is usually 1>OH/NCO>1/
Set it to be 1.3. <Effects of the Invention> The mold of this invention can be bent with a large curvature by using tetraol, which is an alkylene oxide polyadduct of ethylenediamine and has an average molecular weight of about 1100 or less, as the polyol component of the polyurethane forming the transparent synthetic resin layer. Even if the transparent synthetic resin layer is used, cracks will not occur in the transparent synthetic resin layer, and the transparent synthetic resin layer will not peel off from the base body. Therefore, it is suitable as a molding to be attached to a region with a large curvature such as a corner of a vehicle body. <Example> Each polyol component and isocyanate component shown in Table 1 were degassed under reduced pressure (conditions: 50°C x 5
mmHg x 1 hour), then mixed in the indicated amounts and defoamed under reduced pressure again (conditions: 50℃ x 5mmHg x 5 minutes) on a PVC base preheated to 70℃ ( 0.2 to rectangular cross section; width 37mm x height 10mm)
g/cm 2 and kept in an atmosphere of 80° C. for 60 minutes to harden the polyurethane to obtain molds of each Example and Comparative Example. The catalyst was used by being added to the polyol component. Regarding the malls of each example and comparative example,
Tests were conducted on the following items. From the test results in Table 2, it can be seen that the transparent synthetic resin layer of the molding of the example exhibits good bending resistance. Further, the transparency of the transparent synthetic resin of each example was also good. (1) Bending test The molding kept in an atmosphere of 70℃ was bent and immediately wrapped around a 40mmφ pipe at approximately 120° to check for cracks in the transparent synthetic resin layer and peeling from the base body. Judgment was made visually.
