Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window materials made of transparent plate-like bodies, particularly glass plates, synthetic resin plates, etc., such as flat plate-shaped, bent plate-shaped raw or reinforced Architectural window materials, vehicle window materials, etc. made of single, laminated, laminated, multi-layered sheets, and membrane-treated surfaces, etc.
In particular, the present invention relates to a window material for automobiles in which a synthetic resin molding or gasket (hereinafter also referred to as molding) is directly planted on the outer surface of the periphery, and a method for manufacturing the same.

[Conventional technology]

Conventionally, the means for attaching transparent plate-like bodies such as glass plates to vehicle window openings has been to fit them into the joint between the inner panel and outer panel of the vehicle body and the peripheral edge of the glass plate. The glass plate is attached to the car body through a separately molded weather strip, and the legs are inserted between the glass plate and the periphery of the glass plate mounting flange on the car body panel and fixed with adhesive. The so-called direct glazing method, which uses a molded peripheral molding, has been adopted, and the mounting method that has been attracting attention recently is to directly integrate a molding or gasket onto the outer surface of the peripheral edge of the glass plate in advance using a reaction injection molding method, etc. The so-called encap Schlägeron method, in which a molded product is easily attached to a vehicle body using adhesives or the like, is being adopted.

Among them, for example, Japanese Patent Application Laid-Open No. 61-66645 describes a window material assembly and a method for manufacturing the same, which includes a main body made of a transparent plate material and a transparent composite material overlapped and bonded to at least one side of the main body. Tear-resistant window assemblies are disclosed having layers of resinous material and gaskets formed and bonded in-situ around the peripheries of these areas and methods of making the same.

Furthermore, Japanese Utility Model Application Publication No. 61-158508 describes a windshield glass detachment structure, which includes a holding means for detaching the glass from the vehicle body when an impact to the windshield glass exceeds a predetermined value, and a gap between the glass and the vehicle body. Disclosed is an absorbing means attached to the windshield directly or through a holding means to absorb energy received by the glass when the glass moves, and is intended to reduce the collision load of an occupant against the windshield glass in the event of a vehicle emergency. etc. are known.

[Problem that the invention seeks to solve]

As mentioned above, the conventional method described in JP-A No. 61-66645 is intended to prevent tearing by providing a layer of transparent synthetic resin material on a transparent plate material. A polymer frame member is formed on-site to surround the peripheral edge, and both the transparent plate material and the synthetic resin material layer are intended to have sufficient adhesion at the peripheral edge, but rather the transparent plate material The purpose is to sufficiently adhere the synthetic resin material layer to the window material, and the polymer frame member surrounding the peripheral edge of the window material itself is not necessarily fully utilized to absorb impact energy in the event of a collision. It's something that doesn't exist. Furthermore, in the device described in Japanese Utility Model Application Publication No. 61-158508, the member provided at the end of the windshield glass has a complicated shape, the number of members is large, and the structure of the holding and absorbing means is complicated. The dimensions required a high loading capacity, and the installation work was inefficient.
Furthermore, there were other problems such as the need for a certain shape for the instrument panel of the vehicle body.

[Means for solving problems]

The present invention has been made in view of the above drawbacks of the conventional art, and a spring mechanism is provided to press the decoration and reinforcing member onto the inner surface of the mold without contacting the transparent plate-like member within the cavity, so that the decoration and reinforcing member are brought into close contact with the inner surface of the mold. The present invention provides a window material and a manufacturing method thereof that can solve the above-mentioned problems by integrally molding a molding or a gasket on the peripheral edge of a transparent plate-like body.

That is, the present invention provides a window material in which a molding or a gasket made of synthetic resin is integrally molded on the outer surface of the peripheral edge of a transparent plate-like body, and at least one through hole is provided at a required location on the peripheral edge of the transparent plate-like body. A spring mechanism member is provided by connecting the decorative/reinforcing member on the outer surface of the molding or gasket and the base material facing the back surface with a spring mechanism member passing through the through hole. A window material characterized by being integrally molded to incorporate a window material, and a method of integrally molding a synthetic resin molding or gasket on the outer surface of the peripheral edge of a transparent plate-like body, wherein The portion is placed in a mold, and at least - or more through holes are bored at required locations on the peripheral edge of the transparent plate-like body, with a spring mechanism member passing through the through holes,

The inner surface of the mold, the outer surface of the peripheral edge of the transparent plate-like body, and the decoration
The present invention provides a method for manufacturing a window material, which is characterized in that a synthetic resin is integrally molded into a cavity space formed by the inner surface of a reinforcing member, and then taken out from the mold.

Here, the term "transparent" in the transparent plate-like material refers to transparent, translucent, colored, uneven surface patterns, etc.;
Various types of glass for doors, etc., such as flat glass, tempered plate glass by heat treatment or chemical treatment, laminated glass of various degrees such as glass plates and resin plates, and various surface treatments such as heat ray reflective coating, tear prevention coating, black frame, etc. Various types of inorganic glass such as laminated glass, bent sheet glass, double-layered glass, polycarbonate, acrylic, hard-coated synthetic resin sheets such as scratch-resistant, and laminates made of these synthetic resin sheets and inorganic glass sheets. .

The through-holes to be bored in the peripheral edge of the transparent plate-like body should have a diameter that does not come into contact with the spring mechanism member, a shape similar to that of a through-hole, and a number of through-holes at required locations around the entire circumference. At least one or more is required, and it is better to provide it in the same cross-sectional area as the locking lip for better strength, but it may be provided in other locations.

The molding that is integrally molded onto the transparent plate-like body is applied to the peripheral edge of the transparent plate-like body all around or almost the entire circumference, and various shapes are adopted for the molding, but there are a few. (Both are integrally molded on one of the front and back sides and end faces of the peripheral edge of the transparent plate-like body, and it goes without saying that in this case, it is preferable to apply a primer to the required areas in advance to improve the adhesive strength,
The outer surface of the molding preferably has a shape that satisfies a more aerodynamic structure and does not cause unpleasant wind noise, and is preferably provided with a tongue portion to improve sealing performance with the outer skin of the vehicle body. It is preferable that the back surface of the tongue piece has an uneven shape or a shape that has some kind of spring effect, and furthermore, a protruding piece is provided around the entire circumference of the transparent plate-like body on the rising surface corresponding to the end face side of the transparent plate-like body. It is preferable to provide a seal (for sealing) or to have a flexible hollow tube built into the surface of the tube so that it can be sealed, and also to fix it with adhesive when installing it in alignment with an opening in the vehicle body, etc. For engagement and fixation, the back side of the molding has an uneven or concave shape to prevent the bead-shaped adhesive applied to this area from leaking, and a dam part is provided at the end for the purpose of sealing. It is preferable to provide at least one locking rib portion that serves to position the window material at the vehicle body opening, to secure it until the adhesive is fixed, and to assist with subsequent fixing.

The method for molding the molding can be a general synthetic resin molding method such as an injection molding method, and in particular RIM
Reaction Injection Moldi
ng), R-RTM method (particularly those containing reinforcing materials), LIM method (Liquid Injectio
nMoldtng) and the R-L 1M method (particularly those containing reinforcing materials);
Preferably, the IM method is used. That is, 100°C is generally required, for example, while the temperature of the part of the mold surrounding the cavity space is about 200-300°C.
~ room temperature, preferably as low as 50 to 80°C. It is preferable to be able to control the temperature of not only the mold holding temperature, but also the non-molding part, since it is possible to control the solidification rate, etc. Items that require extremely high pressure of 350 to 1000 kg/- are normal pressure to approximately 6 kg/-
It is injected into the cavity space at a pressure within a range of about 3 kg/crA, preferably around 3 kg/crA, and has the advantage that, for example, two components can be mixed by collision and then reacted and injected at extremely low pressure. The mold itself is not particularly limited, and may be made of extremely common metal, resin, or ceramic (also, the surface of the cavity space may be treated with a mold release agent or a transparent plate In order to prevent the surface of the shaped body from being damaged or destroyed, and to prevent the generation of cracks or to absorb the deformation of the mold and the transparent plate-like body, it also serves as a sealing member that is a cushioning member different from the injected resin. Materials such as heat-resistant fluororesin or fluororubber, silicone resin or silicone rubber, other soft resins, etc., elasticity of single bodies, foams, hollow bodies, composite bodies, etc. are interposed between the transparent plate-like body and the mold surface. Needless to say, it must be sealed tightly.

The decorative/reinforcing members set in the mold can be metal or resin films or plates of various sizes, thicknesses, and shapes.Since these are set by a spring mechanism, mold clamping is easy. In conjunction with this, it can be firmly clamped and fixed in the mold regardless of the transparent plate-like object, and it can also absorb distortions of the mold and the transparent plate-like object, and does not cause positional distortion during injection injection of synthetic resin. It allows accurate positioning, and after solidifying from the liquid state of the synthetic resin, the spring force can be eliminated by the resin, making it sturdy.The strength of the spring force also varies depending on the synthetic resin used. You can also freely choose
Various materials and types of spring mechanism members can be selected, and springs are preferred.

The spring mechanism member is directly bonded to, for example, the outer panel of the vehicle body, and as a result, the decoration/reinforcement member is also a spring mechanism member that is attached directly to the outer panel of the vehicle body, regardless of the molding.

Synthetic resins used in the various molding methods described above, that is, synthetic resins that can be used in the present invention, include, for example, polyurethane resins, low density and high density polyethylene, polystyrene, polypropylene, silicone resins, polyamide resins, and nylon-6. , EVASPET, PBT and other thermoplastic resins, polyurethane-based, ethylene-vinyl acetate-based, polyolefin-based, styrene-butadiene-based and other thermoplastic rubbers, vinyl ester resins, epoxy resins,
Examples include thermosetting resins such as silicone resins and unsaturated polyester resins, as well as blended resins, polyurethane foams, elastomers and elastic rubbers, which can be widely used, as well as ultraviolet absorbers, colorants, It goes without saying that fillers such as catalysts, blowing agents, and stabilizers may be added to control the reaction rate, as well as reinforcing agents such as glass fibers and glass flakes, which improve the spring force of the spring mechanism. In addition to determining the strength of elasticity, weather resistance, heat resistance, strength, coefficient of thermal expansion,
It is necessary to consider reduction ratio, surface texture, etc.

[Effect]

As mentioned above, the window material and its manufacturing method of the present invention enable various decorative and reinforcing members to be integrally molded by various combinations of the spring force and holding force of the spring mechanism, and the physical properties of the metal or synthetic resin molding itself. At the same time, the decoration and reinforcing members that become the outer surface can be attached and held directly to the frame, for example, the outer panel of the vehicle body, using spring mechanism members, reducing the impact load on the occupant's window shield glass even in the event of a vehicle collision, for example. It provides more functional effects, such as relaxation and increased penetration resistance.

In other words, the spring force of the spring mechanism allows the decorative and reinforcing members to be reliably positioned within the formwork, and the transparent plate-like body can be held in pressure contact with the inner surfaces of the cavity mold and core mold without any load, and the mold can be clamped. Furthermore, it is possible to absorb the deformation of the mold as well as the pressing force, and also to prevent the occurrence of misalignment when injecting liquid synthetic resin, and to prevent the occurrence of flakes on the outer surface of the decorative/reinforcing member. Become. Additionally, depending on the holding force of the spring mechanism, decorative/reinforcing members can be molded in a variety of sizes, thicknesses, and shapes, and can be integrally molded to improve finishing accuracy. The work of attaching and gluing these parts to the outer panel of the vehicle, which was previously done later, is no longer necessary, and the finished product can be finished with an aesthetic appearance, while also making full use of the physical properties of the integrally molded synthetic resin molding. become,
For example, transparent plate-like bodies can be made more flexible and absorb the impact energy of objects.
By being able to freely select from a wide range of highly functional moldings, and also by making use of their own elasticity, it is possible to eliminate variations in surface inclination accuracy and distortion between the window material and the frame of the vehicle body exterior panel, etc., during installation. It is possible to flexibly respond to these conditions, and the sealing, adhesion, and fixing properties with them can be greatly improved, improving the maintenance of watertightness and airtightness, and as a result, the holding power and durability of the transparent plate. The number of parts has increased, and installation can be easily automated or automated by machines without creating stress during work, and installation can cause damage to the transparent plate, destruction, etc. It is something that will never be done.
