Abstract

The utility model relates to an automobile backstop glass for preventing tempering and blanching. The glass comprises a glass main body, wherein a heating component is arranged on the glass main body; the heating component comprises two bus bars arranged on the two sides of the glass main body and a plurality of heading main bodies which have good electric conductivity and connected in parallel between the two bus bars; the surface of each bus bar is uniformly printed and covered with a black printing ink layer; by printing a silver paste layer at a welding position of the bus bar, the automobile backstop glass after tempering can be welded in 15 seconds by an operator; the welding tension totally can completely meet the quality requirement of standard 80N; and the welding tension of the printed glass is improved more than one time than that of the glass which is not printed, so that the situation of unqualified welding tension is completely avoided. By printing the black printing ink layer on the surface of the bus bar, the bus bar is covered, the black printing ink layer on the surface of the bus bar can absorb heat normally, so that the glass main body is easy to form; and the black printing ink under the silver paste can be fully sintered, and the phenomenon of blanching does not appear.

Description

Prevent the automobile back windshield that tempering turns white

Technical field

The utility model relates to back windshield, more particularly, relates to a kind of automobile back windshield that prevents that tempering from turning white.

Background technology

For shelves glass behind the automobile, can on glass main, print heat generating component through after the silk-screen operation; After accomplishing the silk-screen operation, need carry out tempering to shelves glass behind the automobile and handle, yet; Shelves glass carries out tempering when handling after to automobile because shelves glass dual-side printing bulk bus behind the automobile, when tempering is handled because the white of bus meeting reflecting heat; The heat absorption of the glass of bus lower surface not exclusively causes behind the automobile not easy-formation of shelves glass, and bus back side black ink is easy-sintering and turning white not.

The utility model content

The technical problem that the utility model will solve is, to the above-mentioned defective of prior art, a kind of automobile back windshield that prevents that tempering from turning white is provided.

The utility model solves the technical scheme that its technical problem adopted: construct a kind of automobile back windshield that prevents that tempering from turning white, it comprises glass main, and said glass main is provided with heat generating component; Said heat generating component comprises: be arranged on two buses of both sides on the said glass main, and be arranged on many good conductive exothermal main bodys that are connected in parallel between two buses; Surface at every bus all prints additional the covering black ink layer.

Prevent that said bus is a silver slurry bus in the automobile back windshield that tempering turns white in that the utility model is described.

Prevent that said many good conductive exothermal main bodys are spaced between said two buses in the automobile back windshield that tempering turns white in that the utility model is described.

Prevent that said many good conductive exothermal main body equi-spaced apart are arranged between said two buses in the automobile back windshield that tempering turns white in that the utility model is described.

Prevent that said good conductive exothermal main body is processed by tungsten filament in the automobile back windshield that tempering turns white in that the utility model is described.

Prevent that the spacing of adjacent two good conductive exothermal main body is 1.8mm～5mm in the automobile back windshield that tempering turns white in that the utility model is described.

Implement the automobile back windshield that tempering turns white that prevents of the utility model; Has following beneficial effect: through printing additional black ink layer at the bus upper surface; Bus is covered in, and the black ink above the bus can normally absorb heat, makes easily moulding of glass main; Black ink below the silver slurry also can tight burning, the phenomenon that can not occur turning white.

Description of drawings

To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:

Fig. 1 is the structural representation that the utility model prevents the automobile back windshield that tempering turns white;

Fig. 2 is the end view of Fig. 1.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As illustrated in fig. 1 and 2, the utility model prevent that it mainly comprises glass main 1 in the automobile back windshield that tempering turns white, this glass main 1 is provided with heat generating component; This heat generating component links to each other with external power source; Thus, in the environment that temperature reduces, when shelves glass is loaded on the automobile behind this automobile; Can pass through energized; Make this heat generating component produce heat, and conduct heat on the glass main 1, thereby prevented that effectively shelves frosting on glass is with icing behind this automobile.

This heat generating component mainly comprises: two buses 11 and the good conductive exothermal main body 12 of Duo Gen, and these two buses are arranged on the both sides of this glass main 1, when concrete design; Preferably, be arranged on the left and right sides, for about definition; Be the position when being installed on the automobile according to behind this automobile grade of glass, that is, and when shelves glass is installed on the automobile behind the automobile; Side near roof is a upside, is downside near the side on ground, and both sides are the left and right sides in addition.Many good conductive exothermal main bodys are connected in parallel between two buses, and the two ends of every good conductive exothermal main body 12 are connected with bus 11 respectively, thus, are connected with external power source through two buses 11.As shown in Figure 2, on every bus 11, add and be printed on black ink layer 13, thereby can cover buses 11 through this black ink layer 13; Thus through printing additional black ink layer at the bus upper surface; Bus is covered in, and the black ink above the bus can normally absorb heat, makes easily moulding of glass main; Black ink below the silver slurry also can tight burning, the phenomenon that can not occur turning white.

In actual use, this bus 11 is silver slurry buses.These many good conductive exothermal main bodys 12 can be spaced between two buses 11, and preferred, these many good conductive exothermal main body 12 equi-spaced apart are arranged between two buses 11.This good conductive exothermal main body 12 can be processed by tungsten filament.The spacing of adjacent two good conductive exothermal main body 12 is 1.8mm～5mm.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
