Abstract

The utility model relates to an edge covering skylight glass without refraction on a surface. The edge covering skylight glass without the refraction on the surface comprises a glass component, a PU (poly urethane) material layer, a metal reinforcing piece and an embedding piece, wherein the PU material layer is covered on the glass component; the metal reinforcing piece is wrapped in the PU material layer; and the embedding piece is glued on the metal reinforcing piece. The preparation method of the edge covering skylight glass without the refraction comprises the following steps of: cleaning the glass component, coating bottom coat, cleaning the metal reinforcing piece, gluing the embedding piece in the U-shaped groove of the metal reinforcing piece, and charging the metal reinforcing piece and the glass component into a mould to be positioned; carrying out the injection molding on a PU edge covering material in a sealing way by the mould; completely packing the embedding piece between the PU material layer and the metal reinforcing piece; and after solidifying for a while in a cooling way, withdrawing the piece by opening the mould, so that the edge covering skylight glass without the refraction can be obtained. Compared with the prior art, the preparation method of the edge covering skylight glass without the refraction on the surface is simple to operate, the binding power between the PU material layer and the glass component can not be reduced, the function of the skylight glass can not be influenced, and the edge covering skylight glass is better in surface optical performance.

Description

A kind of surface no refractive power bound edge skylight glass

Technical field

The utility model relates to a kind of skylight glass, especially relates to a kind of surface no refractive power bound edge skylight glass.

Background technology

Along with the scientific and technological great-leap-forward development in the whole world, also obtain tremendous development as the auto-industry of one of science and technology strength representative, and automobile bound edge glass is crucial parts in the contemporary automobile, people have also proposed higher harsher technical requirements naturally to this.Bound edge glass in the vehicle glass; Particularly on overall performance, to have a filling pressure low for PU reaction injection molding (RIM) bound edge glass; Energy consumption is low, and the goods design flexibility is big, and molding cycle is shorter; Speciality such as the strong and product design of comformability is superior has greatly satisfied the ladder demand of different clients to vehicle glass production supply and demand.

Automobile skylight glass needs opening and closing; Usually structure design all has metal reinforcement; Promptly before the bound edge injection moulding, need in mould, preset into some iron inserts; The part of the metal reinforcement that presets or all be coated in the PU material layer, strengthen the shock resistance of skylight glass and accomplish the rigidity of skylight glass during injection mo(u)lding.

Skylight injection moulding bound edge glass is owing to include metal reinforcement, and the zone of PU and glass contact scribbles the extremely strong primary coat of one deck cohesiveness in advance, primary coat and PU material and glass generation cross-linking reaction after the PU injection mo(u)lding; The PU material can produce certain shrink when curing reaction simultaneously; Because metal, glass and these three kinds of materials of PU rubber receive percent thermal shrinkage inconsistent; The PU material carries out necessarily " pullling " to metal reinforcement and glass like this, and the contraction of PU material passes for to interior surfaces of glass through priming coat, produces a tractive force in the interior surfaces of glass normal orientation; Cause glass surface to produce depression, just so-called refractive power.

The utility model content

The purpose of the utility model is exactly that the effective thickness little, the no refractive power phenomenon of contraction, the optical property little, the PU material that provide a kind of PU to expect for the defective that overcomes above-mentioned prior art existence better do not have refractive power bound edge skylight glass.

The purpose of the utility model can realize through following technical scheme:

A kind of surface no refractive power bound edge skylight glass; Comprise glass elements, PU material layer, metal reinforcement and inserts; Described PU material layer is sticked in a side of glass elements, wraps up in the PU material layer and is provided with metal reinforcement, and described inserts is adhesive on the metal reinforcement.

Offer U type groove in the described metal reinforcement.

Described inserts is adhesive in the U type groove of metal reinforcement.

Described inserts and PU material layer can carry out fine bonding.

Described inserts is provided with one or more.

Materials flow balance when the utility model changes the filling of PU material layer through on metal reinforcement, increasing inserts, thus reach the thickness of balanced each different parts PU material layer, improve the problem of bound edge skylight glass refractive power.

Compared with prior art; It is simple to operate that the utility model prepares the method for no refractive power bound edge skylight glass, can effectively reduce the effective thickness of product P U material layer, reduces the contraction of PU material layer; Solve glass and produce the phenomenon that depression causes the glass surface refractive power because the cooling of PU material layer is pullled; The utility model does not reduce the cohesive force between PU material layer and the glass elements again, does not influence the skylight glass function, and the no refractive power bound edge skylight glass surface optical performance of the utility model preparation is better.

Fig. 2 is common bound edge skylight glass structural representation.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.

Embodiment

A kind of surface no refractive power bound edge skylight glass; Structure is as shown in Figure 1, comprises glass elements 1, PU material layer 2, metal reinforcement 3 and inserts 4, and PU material layer 2 is coated on above the glass elements 1; Metal reinforcement 3 is wrapped in PU material layer 2 the insides, and inserts 4 is adhesive on the metal reinforcement 3.Metal reinforcement 3 is provided with U type groove.The inserts 4 that the U type groove that inserts 4 can be put into metal reinforcement 3 for shape satisfies requires.Inserts 4 is for can carry out fine bonding inserts 4 with PU material layer 2.Inserts 4 is one or more.Inserts 4 is adhesive in the U type groove of metal reinforcement 3.

The method for making of the no refractive power bound edge skylight glass in surface may further comprise the steps:

(1) the cleaning glass element 1, is coated with primary coat, places a period of time;

(2) the clean metal reinforcement 3, at least one inserts 4 are adhesive in the U type groove of metal reinforcement 3;

(3) metal reinforcement 3 and glass elements 1 are gone into the mould location;

(4) it is middle with metal reinforcement 3 that mould closes injection moulding PU bound edge material, inserts 4 are wrapped in PU material layer 2 fully;

(5) after between one section of the cooling curing, the die sinking pickup promptly obtains not having refractive power bound edge glass sunroof.

Common bound edge skylight glass structure is as shown in Figure 2, comprises glass elements 1, PU material layer 2 and metal reinforcement 3, and PU material layer 2 is coated on above the glass elements 1, and metal reinforcement 3 is wrapped in PU material layer 2 the insides.The structure that is different from the utility model; The metal reinforcement of common bound edge skylight glass is not provided with inserts; Have the refractive power phenomenon; And the materials flow balance of the utility model when changing 2 fillings of PU material layers through on metal reinforcement 3, increasing inserts 4, thereby reach the thickness of balanced each different parts PU material layer 2, improve the problem of bound edge skylight glass refractive power.
