Description
Technical field
The present invention relates to automobile, train windshield glass technology, more particularly to a kind of electrical heating vehicular windscreens glass.
Background technology
Vehicle glass is one of important safety component of automobile, with protection occupant safety and waterproof and dustproof, it is heat-resisting and
Sound insulation etc. is acted on.Nowadays, the area of vehicle glass accounts for the 1/3 of car surface product.According to application site, automotive glass master
Will be including windshield glass, wind shield glass wind shield, door glass, skylight glass and front/rear quarter light glass etc..Early in before more than 40 years, vapour
Car windshield has used single-piece to bend windshield, and has gradually abandoned the windshield of plane.The automobile of today
Windshield typically all makees the large curved surface type of integral width formula, there is certain radian up and down.With auto industry
Development, widely, it is almost applied to the rear seat windscreen of all automobiles to the vehicle glass application with heater wire, it
It is the surface that special conductive silver paste is printed onto glass by way of wire mark, after tempering, conductive silver paste is sintered to glass
Glass surface, can generate heat to eliminate the frost of glass surface because it has certain resistance, after energization, be beneficial to driving
Person can in time observe the situation at car rear in driving, automobile is had more preferable comfortableness and safety in driving procedure
Property.
But this automobile electrothermic windowpane be using line heating by the way of, heater wire heating after, slowly by heat to
Heater wire both sides are transmitted, and vehicle glass is heated uneven, once heat temperature raising excessive velocities, or the heat time is long, holds very much
Easily there is the situation of vehicle glass explosion.In addition, this automobile electrothermic windowpane is the printing heater wire (conductive silver on glass
Line), in order to reach good heating effect, the printing width of usual heater wire is not less than 1mm, and a common car
Rear seat windscreen at least more than ten to twenties heater wires not waited, these visual heater wires to the outward appearance of automobile and
The sight line of driver and crew all brings certain influence.
U.S. patent Nos US5540961 discloses a kind of " having the windshield of wire thermoplastic interlayer ", the patent
Employ it is a kind of superfine metal tungsten wire (20-50 micron diameters) is laid on the technical scheme in the interlayer of automobile front windshield,
The function of electric heated defrosting, demisting and deicing can be realized, the disadvantage of this scheme is cost very high, and another is obvious
Shortcoming be presence that driver or passenger can significantly see filament, influence attractive in appearance and sight line.
Chinese invention patent application 201210333292.1 discloses that " one kind can electrically heated low-emission coated interlayer glass
Glass ", the patent employs the compound film system containing Ag layers He low-emission coated layer, and surface resistance is reduced into 0.4-4ohm/.
Although the program has more preferably electric conductivity and bigger heating power, because using multicoating, undoubtedly also increasing greatly
Cost is added.
Chinese invention patent CN 98100128.9 proposes a kind of " preparation method heat-insulated, every white coated glass ", and this is special
Profit proposes to replace existing heater wire windowpane with ITO conductive film glass window, and this ITO conductive film glass resistance is low, can
See that light transmission rate is high, abandoned the printing of traditional heater wire, beautified automobile appearance, make to drive comfortableness and security is obtained
Improve.However it is necessary that proposing, Hyundai Motor almost uses bending windshield completely, therefore in the processed of windshield
, it is necessary to carry out hot bending operation to plate glass in journey, this operation needs to be carried out at a temperature of 600 DEG C or so.According to making
Technique, hot bending operation will complete ITO conductive film plated films after carry out, but ITO conductive films in temperature more than 300
DEG C when, surface resistance can steeply rise.So if using ito coated glass as vehicle glass, its heating power is not reached much
Eliminate the requirement of glass for vehicle window ice and snow frost.
Our company acts on electrical heating in the Chinese patent CN 201410649122.3 of recent application using FTO electro-conductive glass
The new technology of automobile wind shield glass, using face mode of heating, is heated evenly, and is not likely to produce explosion, defrosting, snow removing, the speed of deicing
Degree is fast, and all-transparent, and good appearance.But, because FTO electro-conductive glass characteristic in itself, commercialized FTO electro-conductive glass
Square resistance it is general at 7~15 ohm, in order to reach the effect of heating, exactly reach the face heating power of requirement, generally
300-600W/ ㎡, must just be equipped with appropriate heating voltage, usually 30V~60V.General-utility car 12V storage battery power supplies,
And new energy motor, by the lithium battery power supply of 100~400V, train is then by 220V AC-powereds.All these applications need
Voltage change device.Either commutator transformer or transformer can all increase cost, increase weight, and the preciousness for occupying car is empty
Between, while producing part energy to waste.

Drilling, washing, surface dirt, greasy dirt, impurity etc. are cleaned up, and the glass substrate after washing is dried, and notes drying
Glass substrate afterwards can not directly be touched with hand.
Step 2：With laser ablation, the FTO conductive areas of 2 left-right layout parallelogram shown in Fig. 5, twoth area are reserved
Block size is identical, a length of 1500mm of longitudinal edge of parallelogram, and the distance between two length of sides are 850mm, the electricity of each block
It is 17.6ohm to hinder, and the conductive gross area is 2.55m2, all-in resistance is 35.3ohm.
Step 3：In the opposite side up and down (short side) of parallelogram FTO conductive areas, 10mm conductive silvers wide are printed respectively
Bar 4, and wherein connect the conductive silver wire of side, opposite side is to form positive pole 5, negative pole 6.
Step 4：By the common glass substrates 2 of the thickness 4mm of same size after being processed with step 1, identical chi is obtained
Very little common glass substrates.Unlike, the position that common glass substrates 2 correspond to Ag bars one end of glass substrate 1 needs in advance
First drill, aperture is 8mm.
Step 5：The above-mentioned plane FTO conducting glass substrates handled well and common glass substrates 2 are placed horizontally in respectively respectively
From mould on, deliver to heating stove heat, when glass temperature reaches 620 DEG C or so, two sheet glass are distinguished with vacuum cup
Pick up, overlay and free-falling is done on mould, be labelled to mould because Action of Gravity Field is sagging and shape, after keeping 10min, rapidly will
It is sent to cooling air grid area, and high pressure cold air is blowed to the two sides of glass with bull nozzle, and chilling tempering is strong needed for directly obtaining
The bend glass of degree and curvature.
Step 6：In FTO conducting glass substrates 1 and the middle placing clamp glued membrane of glass substrate 2, to good position after, as doubling
Doubling is carried out in stove.
Step 7：By the aperture reserved in common glass substrates 2, respectively by positive pole:5th, the conductive silver bar 4 of negative pole 6 passes through
Wire is connected with 220V AC powers, so that electric current is by FTO conductive films and heated glass window, the general power of heating is
1370W, power density is 538W/m2。
Above-mentioned non-limiting example can make one of ordinary skill in the art be more fully understood the present invention, but not with
Any mode limits the present invention.Any one skilled in the art in the technical scope of present disclosure, according to
Technical scheme and its inventive concept carry out equivalent or change belongs to protection category of the present invention.
