Description
Technical field
The utility model belongs to vehicle glass technical field, and in particular to a kind of automobile front wind screen compound glass vehicle window.
Background technology
The initial effect of vehicle glass is resistance to colds, barrier rainwater, is given birth to the development and people of auto industry
Quality advance living, the more and more important role of the gradual performer of vehicle glass.Since the fifties in last century, vehicle glass is especially
It is that windshield glass of automobile is lived through from ordinary plate glass to heat-bending glass successively, then from full tempered glass to region tempering glass
The transformation of glass.National standard《GB9656-2003 automotive safety glass》Middle regulation, windscreen（Windscreen）It is applicable
Type has laminated glass, local toughened glass, modeling glass composite and safety glass, wherein laminated glass and modeling glass composite
Suitable for all motor vehicles, and local toughened glass is applied to the cargo vehicle of manned purpose, safety glass not be applied to
Desin speed is less than 40Km/h motor vehicle.From technological layer, before laminated glass and the composite making of modeling glass
Windscreen vehicle window has the advantages that light weight, intensity are big.
Conventional vehicle window windshield glass uses glass, PU glue-line and PC of the thickness for 2 ~ 3mm using modeling glass composite
Plate is compound, or two layers of common soda-lime-silica glass intermediate course that laminated glass uses uses PVB plastic cement to solidify；Using above-mentioned
Mould glass composite and be capable of wanting for compound national Specification as automobile front windshield glass for vehicle window, thickness and impact resistance
Ask, but the toughness of material, passenger want to meet with obstruction by front windshield car window escaping when facing a danger.And use folder
Layer glass, 5mm is generally larger than because laminated glass thickness is larger, heavier mass itself, causes used automobile fuel consumption amount
Increase, and laminated glass possesses certain penetration-resistant energy, wants to realize that in-car escape is also more difficult.
The thickness of domestic automobile windshield is generally large, and the thickness of front windscreen for vehicle is generally by vehicle classification
5mm ~ 7mm, side window glass thickness 3mm ~ 5mm of car.Because thickness causes windshield quality big, so as to improve vehicle body indirectly
Quality, increase the oil consumption in vehicle traveling process, so the frivolous automobile using windshield of design safety is current hair
Exhibition trend.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of automobile front wind screen compound glass car
Window.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of automobile front wind screen compound glass vehicle window, described compound glass vehicle window have high two layers aluminosilicate glass；Two
PVB pyrocondensation glue-lines are provided between high aluminosilicate glass described in layer；The thickness of two layers of high aluminosilicate glass be 0.70mm ~
Big 0.05 ~ the 0.20mm of thickness of 1.20mm, wherein internal layer thickness ratio outer layer；The thickness of the PVB pyrocondensations glue-line be 0.20mm ~
0.70mm；Described compound glass for vehicle window gross thickness is 2.50mm ~ 3.50mm.
The utility model proposes a kind of automobile front wind screen compound glass vehicle window, and described windshield glass of automobile is using multiple
Layer design is closed, there is in light weight, thickness as intermediate layer as outer layer and internal layer, PVB pyrocondensations glue-line using high aluminosilicate glass
The features such as small, impact resistance, good sound insulation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1, high aluminosilicate glass, 2, PVB thermoplastic glue-lines.
Embodiment
The utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
As shown in figure 1, a kind of automobile front wind screen compound glass vehicle window, described compound glass vehicle window has two layers of high alumina
Silica glass；PVB pyrocondensation glue-lines are provided between high aluminosilicate glass described in two layers；The thickness of two layers of high aluminosilicate glass is
Big 0.05 ~ the 0.20mm of thickness of 0.70mm ~ 1.20mm, wherein internal layer thickness ratio outer layer；The thickness of the PVB pyrocondensations glue-line is
0.20mm~0.70mm；Described compound glass for vehicle window gross thickness is 2.50mm ~ 3.50mm.
The high aluminosilicate glass 1 of outer layer need to carry out it is chemical enhanced, it is described it is chemical enhanced be using potassium nitrate, carbonic acid
The mixed salt of potassium and potassium chloride, for the content of potassium nitrate more than 92% ~ 95%, the content of potassium carbonate and potassium chloride is total in described mixed salt
Meter is below 8% ~ 5%.The mixed salt of described potassium nitrate, potassium carbonate and potassium chloride is heated to 420 DEG C ~ 460 DEG C in salt bath,
The high aluminosilicate glass of above-mentioned forming is put into salt bath after 7h ~ 11h and taken out.Described ultra-thin high aluminosilicate glass is chemical strong
Rupture strength after change can reach 820MPa ~ 860MPa.
The high aluminosilicate glass of internal layer is needed to carry out physical region tempering, and physical region tempering is referred to using heat treatment
Process, the high aluminosilicate glass above by gained after annealing is placed in annealing furnace and is heated to close to softening temperature, this implementation
Example in be heated to 520 DEG C, be subsequently placed in the air grid of different intensities of cooling, glass center section for weak cold air grid part,
The neighboring area of glass is in the part of strong cold wind grid, and the purpose is to uneven cooling is carried out to glass so that among glass
Region and the neighboring area of glass have different stress, and the surface stress of neighboring area glass is larger and intermediate region glass
Surface stress is smaller.Final result is to cause glass to become local toughened glass, and peripheral part toughening degree is high and middle
Part toughening degree is low.
PVB pyrocondensation glue-lines used in the present embodiment（2）It is to be placed on outer layer and the high aluminosilicate glass of internal layer with PVB films
Centre, then formed by laminated glass combination process.In the present embodiment used its main component of PVB films be 65% ~
78% polyvinyl butyral resin, 19% ~ 32% polyvinyl alcohol and the polyvinyl acetate less than 3%.Specific implementation process be
Temperature is set in autoclave, and as 135 DEG C ~ 150 DEG C, pressure is 0.8 ~ 1.5MPa, is taken out after 0.5 ~ 4h.
