Exemplary glass piece manufacturing process includes fusion drawing and slot draw process, and example is glass tube down-drawing respectively and floats Method.The sheet glass of chemical strengthening and the sheet glass of non-chemical reinforcing can be formed with these methods.Fusion drawing process makes With container is drawn, there is the channel for being used to receive molten raw.Channel has weir, along the length in channel in channel The open-top of two sides.When with melted material filling channel, melten glass is from weir overflow.Under gravity, glass is melted Glass is flowed down from the outer surface for drawing container.These downwardly and extend internally, so that they are drawing sides below container It is combined at edge.Two flowing glass surfaces are combined in the edge, to fuse and form single flowing sheet material.Fuse drawing The advantages of be, since the two pieces of glass-films flowed through from channel fuse together, obtained sheet glass it is any outer Surface is not all in contact with any component of equipment.Therefore, the surface nature of draw glass sheet is fused not by such contact Influence.

Slot draw is different from fusion drawing.In this method, fused raw material glass is provided and draws container.It draws The bottom of container has open slots, has the nozzle extended along the length of slit.Melten glass flows through slit/spray Mouth is pulled down with continuous sheet material and enters annealed zone.Slot draw process can provide the sheet material thinner than fusion drawing process, Because only monolithic is drawn through slit, rather than two panels is fused together.

Down draw process production has uniform thickness and the sheet glass compared with original tool surfaces.Because the intensity of glass surface by To the control of the amount and size of surface blemish, therefore the smallest initial surface of exposure level initial strength with higher.When with When carrying out chemical strengthening to the high strength glass afterwards, obtained intensity can be higher than the surface for having carried out polishing and polishing Intensity.Downdraw glass can be drawn into the thickness for being approximately less than 2mm.In addition, downdraw glass has very flat, smooth table Face can just be used for final application without high-cost grinding and polishing.

It, can be by making melten glass float on molten metal (usually tin) bed, to make in float glass process Make the sheet glass that may be characterized as having smooth surface and uniform thickness.In example process, melten glass is fed to melting On tin bed surface, floating band is formed.As glass tape is flowed along tin bath, temperature is gradually decreased until can be by solid glass piece It is lifted on roller from tin.Once leaving bath, being carried out to sheet glass further cooling and annealing to reduce internal stress.

Sheet glass can be used to form glass laminate.As defined herein, hybrid glass laminated body includes outside Among the sheet glass of chemical strengthening, the sheet glass of the non-chemical reinforcing inside and the polymer being formed between sheet glass Layer.Polymer interlayers may include monoblock type polymer sheet, multilayer polymeric sheet or composition polymer piece.Polymer interlayers It can be, for example, poly- (vinyl butyral) piece of plasticizing.

Glass laminate is applicable to provide optically transparent resistance in building and automotive openings (such as motor-vehicle glass window) Every.Glass laminate can be formed using various techniques.In the exemplary embodiment, assembling is related to laying the first sheet glass, Polymer interlayers (such as PVB piece) are layered on thereon, the second sheet glass is laid, and are then cut beyond glass sheet edges Excessive PVB.Adhesion step may include most air being discharged from interface, and bond PVB and sheet glass part.Usually exist The correction step carried out under the temperature and pressure of promotion completes the matching of each block of sheet glass and Polymer interlayers.In aforementioned reality It applies in mode, described first sheet glass that can be chemical strengthening and second glass that can be non-chemical reinforcing Glass piece, vice versa.

Table 2: exemplary glass stepped construction

Applicant has shown that glass laminated structure disclosed herein has excellent durability, impact resistance, toughness And scratch-resistant.As well known by the skilled person in the art, the intensity and mechanical shock resistance of sheet glass or laminated body It can be limited by the defects of glass (including two surfaces and internal defect).When glass laminate is impacted, punching It hits and is a little compressed, while the ring or " annulus " around shock point and the apparent surface by the sheet glass impacted are in and draw It stretches in state.In general, destruction can take place from cracks, this is frequently located in highest point of tension or highest on glass surface Near point of tension.This is likely to occur on apparent surface, but it can also happen that in ring.If in impact event, glass In crackle be in stretch, then crackle may extend, and glass would generally rupture.Therefore, the compression stress of high-magnitude and depth (layer depth) is preferred.

Because chemical strengthening acts on, one of chemically reinforced glass piece used in revealed hybrid glass laminated body or Two surfaces are in compressive state.In the near-surface region combination compression stress of glass, can inhibit sheet glass crack propagation and Failure.In order to which crack propagation and failure occurs, the tensile stress from impact must be more than that surface is pressed at crack tip Stress under compression.In some embodiments, the high compression stress of chemically reinforced glass piece and high layer depth allow using than non-chemical Thinner glass in the case where strengthened glass.

In the case where hybrid glass laminated body, stepped construction is when responding mechanical shock, with thicker monoblock type non-ization Strengthened glass is learned, or thicker non-chemical strengthened glass laminated body is compared, can further deflected without being broken.It is this Increased deflection is realized more energy transfers to laminated body middle layer, this can reduce the energy for reaching the opposite side of glass Amount.Therefore, compared with the non-chemical strengthened glass of the monoblock type with comparable thickness or non-chemical strengthened glass laminated body, herein Revealed hybrid glass laminated body can be subjected to higher impact energy.

It will be understood by those skilled in the art that stepped construction can also be used to weaken sound wave other than their mechanical performance. Although hybrid glass laminates disclosed herein can reduce sound wave biography using the structure of relatively thin (and relatively light) significantly Defeated, the structure of described relatively thin (and relatively light) also possesses many glazings using necessary engineering properties.

Flexible vibration of the sound absorbing performance of laminated body and windowpane usually by glazing structure is influenced.Be not intended to by Theoretical display, human body acoustic response peak is usually 500-5000Hz, in the wavelength and glass corresponding to about 0.1-1m in air The wavelength of 1-10m.It is less than the glazing structure of 0.01m (< 10mm) for thickness, it is main to pass through vibration and sound wave and windowpane Bending vibration coupling generate transmission.Laminated glazing structure can be designed to convert energy to from windowpane flexure mode Shear strain in Polymer interlayers.In using the glass laminate compared with thin glass sheet, compared with the larger compliance of thin glass Allow biggish Oscillation Amplitude, this assigns the biggish shear strain of middle layer in turn.Most of viscoelastic polymer middle layer materials The low shear resistant of material means that middle layer can promote damping vibration attenuation by high shear strain, and the high shear strain can divide Heat is converted under the influence of subchain sliding and relaxation.

In addition to glass laminated body thickness, the characteristic for constituting the sheet glass of laminated body also will affect acoustic attenuation property.For example, It, may there are small at glass-polymer interlayer interface between the sheet glass of chemical strengthening and the sheet glass of non-chemical reinforcing , but apparent difference, this leads to higher shear strain in polymeric layer.Similarly, not in addition to their obvious composition With except, alumina silicate glass and soda-lime glass have different Physical and mechanical properties of polyoropylene, including modulus, Poisson's ratio, density etc., This may cause different acoustic responses.

Embodiment

It is tested using conventional uniaxial strengeth, such as 3 points or 4 crooked tests measure the strong of glass and ceramic material Degree.But because surveyed intensity depends on edge effect and bulk material, the explanation to uniaxial strengeth test result is that have to choose War property.

On the other hand, biaxial bending test can be used for providing strength assessment, and the phenomenon that independent of edge induction.? In biaxial bending test, glass laminate is supported on 3 or more the points equidistant close to its circumference and with its center, is then existed Center, which applies laminated body, to be loaded.Therefore, the position of maximum tensile stress is present in the center on laminated body surface, and excellent Selection of land, it is unrelated with its rim condition.

Exemplary planar hybrid glass laminated body is standardized biaxial bending test (the ECE R43 refined in annex 7/3 Headform's test).As explained further below, of the invention when being impacted on non-chemical strengthened glass (soda-lime glass) side When glassy layer overlapping piece (sample 1), two sheet glass are all broken.But when the glass laminate in chemical strengthening side impact sample 1 When, non-chemical strengthened glass piece fracture, but there is 50% chemically reinforced glass piece to remain intact in the sample tested.

In a test, high load rate impact is directly directed to internal (non-chemical reinforcing) sheet glass 120.As Response, the interior surface 124 of inner glass piece 120 and the outer surface 112 of outer glass piece 110 are all in tensional state.By It is greater than the tensile stress at interior surface 124, in this configuration, internal table in the size of the tensile stress on outer surface 112 More medium tensile stress is enough to make the sheet glass 120 of non-chemical reinforcing to be broken on face 124, while outer surface 112 above mentions The tensile stress risen is enough to make the 110 of chemically reinforced glass piece also to rupture.When sheet glass rupture, the deformation of PVB middle layer, But headform's percussion mechanism is prevented to penetrate glass laminate.This is the response for meeting ECE R43 head dummy requirement.

In dependence test, directed outwards (chemical strengthening) sheet glass 110 on the contrary is impacted.In response, external glass The interior surface 114 of glass piece 110 is subjected to medium tensile stress, and the outer surface 122 of inner glass piece 120 is subjected to higher magnitude Stress.In this configuration, the stress promoted on the outer surface 122 of internal non-chemical strengthened glass piece 120 leads to non-ization Learn the sheet glass rupture strengthened.But the medium tensile stress in the interior surface 114 of outer glass piece 110, it may be not enough to The compression stress for overcoming the ion exchange in the near-surface region of chemically reinforced glass to be induced.It is high in laboratory experiment Speed under load impact only causes 2 chemically reinforced glass pieces 110 in 6 tested samples to rupture.At remaining 4 In sample, the sheet glass 120 of non-chemical reinforcing is broken, and still, the sheet glass 110 of chemical strengthening remains intact.Institute of the invention There is sample to be above ECE R43 headform and requires the impact requirement for non-windshield.

Contrast sample A and B also carry out biaxial bending test.Comparative sample A include 1mm chemically reinforced glass piece/ 0.76mm standard PVB/1mm chemically reinforced glass piece symmetric construction, there is no ruptures, therefore do not meet ECE R43 about glass The requirement that glass laminated body must rupture.

Comparative sample B includes sodium calcium glass piece/0.76mm standard PVB/1.5mm soda-lime glass piece symmetric construction of 1.5mm.? In biaxial bending test, 2 blocks of sheet glass are all broken, therefore comparative sample B has passed through ECE R43 standard (annex 7/3).But No matter any block sheet glass is impacted, and 2 blocks of sheet glass of comparative sample B glass laminate are all broken, therefore it is external to provide reply The firm mechanical fastness of impact, and what this was that by mixed layer overlapping piece.It is also pointed out that during the test, The case where rebound (that is, spring) of headform in comparative sample B is greater than sample 1 shows to compare configuration without as the present invention Embodiment effectively dissipation energy like that.

Head injury standard (HIC) is the conventional criteria that can be used for assessing the safety of glass laminate.HIC value is immeasurable The magnitude of guiding principle, to by due to impact bring injure a possibility that it is related.For internal impact event, lower HIC value is In accordance with desired.

For exemplary planar hybrid glass laminated body, 1.6mm SL/0.8mm A-PVB/0.7mm GG is stacked The HIC average value of impact on non-chemical reinforcing side is 175, still, for 0.7mm GG/0.8mm A-PVB/1.6mm SL heap For impact on folded chemical strengthening side, HIC average value is 381.It is (outer for chemical strengthening for motor-vehicle glass window application Portion) the HIC average value of impact on side is preferably greater than the HIC average value of the impact on non-chemical reinforcing side.For example, chemical strengthening The HIC value of side can be greater than or equal to for 400 (for example, being greater than or equal to 400,450 or 500), rather than the HIC value of chemical strengthening side can Less than or equal to 400 (for example, being less than or equal to 400,350,300,250,200,150 or 100), so that chemical strengthening side HIC value than it is non-chemical strengthen side HIC value it is at least big by 50 (for example, at least big 50,100,150 or 200).
