Abstract
The invention discloses a composite structure for a front windshield of an automobile. The composite structure comprises outer layer glass, inner layer transparent glass fiber reinforced plastic, an upper ventilation slot plate and a lower ventilation slot plate, wherein the outer layer glass is common automobile glass; parts which do not shield visual lines on the upper part and the lower part of the inner side of the outer layer glass are coated with at least one electrification radiation silver paste strip respectively; the upper ventilation slot plate and the lower ventilation slot plate are arranged between the outer layer glass and the inner layer glass fiber reinforced plastic; a vent pipe is arranged on one side of the upper ventilation slot plate; a plurality of vent holes which are communicated with the vent pipe are formed in the upper ventilation slot plate; an air inlet pipe is arranged on one side of the lower ventilation slot plate; and a plurality of air inlet holes which are communicated with the air inlet pipe are formed in the lower ventilation slot plate. The composite structure has the characteristics of high impact resistance, long service life, high machinability, high usability, light weight and low cost and is easy to repair. The composite structure is an automobile wind-shielding structure which can be separately produced or can be used for modifying the conventional automobile, can quickly eliminate rime rice outside the windshield in a melting way in winter and contributes to improvement on the safety of the automobile.
Description
Technical field
The present invention relates to a kind of transport facility, be specifically related to a kind of raising automotive crash safety, improve scattering high light ability, effectively completely cut off car internal-external temperature difference environment, the automobile front wind screen window construction that effectively defrosts antifog.
Background technology
Existing automobile cab front windshield mostly is general-utility car glass, and tension, bending strength are low, thereby impact resistance is little; Owing to the coefficient of thermal conductivity height of glass, after turning on the aircondition summer, can waste the more energy; In the winter time after the snowfall, can freeze on the front windshield,, thereby utilize in the car hot blast ice required time longer because when just having started automobile, engine temperature does not also come up; In the rain, the operator's compartment internal-external temperature difference is big, and owing to people's reason windshield faces such as breathing are easily assembled a large amount of water smokes, sight line is poor, has a strong impact on the safety of running; When drive in face of solar direction or night during meeting the other side use country beam, general-utility car glass is the scattering high light well, causes danger easily.
Summary of the invention
The objective of the invention is to provide a kind of impact resistance height, adiathermancy is good, scattering high light ability is strong, can produce separately or existing vehicle is reequiped, in the winter time can be rapid except that Windshield frost, guarantee safe automobile front wind screen structure.
The technical scheme that adopts is:
A kind of shield glass composite structure, comprise glass outer, internal layer transparent grp, last ventilation channel plate and following ventilation channel plate, it is characterized in that: glass outer is a general-utility car glass, scribbles at least one heating power silver slurry respectively in the upper and lower part of not blocking sight line of outer glass inner side.Be provided with ventilation channel plate and following ventilation channel plate between glass outer and the inner layer glass steel, one side of last ventilation channel plate is equipped with a freeing pipe, last ventilation channel plate is provided with a plurality of deflation holes that are connected with freeing pipe, one side of following ventilation channel plate is equipped with into tracheae, offer on the following ventilation channel plate a plurality of with go into the blowhole that tracheae is connected.
Deflation hole on the above-mentioned upper and lower ventilation channel plate and blowhole spacing be all less than 10cm, upper and lower ventilation channel plate adopt bonding or bolted connection on the weatherstrip window framework.
Above-mentioned heating silver slurry major ingredient proportioning is that conductive silver particulate 62-66 gram (granularity is controlled at 3～5 μ m), adhesive epoxy resin or phenol resin 34-38 gram, solvent diethylene glycol monobutyl ether acetate are an amount of.
Above-mentioned inner layer glass steel major ingredient is modified methacrylic acid resin and modification E glass fibre, and described modified methacrylic acid resin major ingredient proportioning is styrene 100 grams, methyl methacrylate 120-380 gram, initiating agent 1.5 grams; Described modification E glass fibre is meant that the E glass fibre soaks into through size, and size major ingredient proportioning is polyester emulsion 300 grams, A-174 coupling agent 18 grams, triethanolamine lauryl sulfate 10 grams, polyvinyl alcohol monostearate 4 grams; Modified methacrylic acid resin proportion should be greater than 85% in transparent grp, and modification E glass fibre should be less than 15%, and fibre length is about 35mm.
The present invention is owing to adopted glass-reinforced plastic material, and its tension, bending strength are higher than glass, can improve the impact resistance of this structure; The glass-reinforced plastic material coefficient of thermal conductivity is lower than glass, and this structure is double-decker, therefore can completely cut off the internal-external temperature difference environment effectively, the reduction expenditure of energy; Glass-felt plastic is a heterogeneous material, itself has the ability of scattering high light; Because this structural outside layers can be existing vehicle glass, thereby be beneficial to existing vehicle is reequiped; Through methacrylic resin and the E glass fibre that modification is handled, its ratio of refraction unanimity, and resin content is greater than after 80%, and the light transmittance of glass-felt plastic can reach more than 90%, works as with glassy phase; Because the glass outer upper inner scribbles heating power silver slurry and circuit is a curve, ice during cycling start just in the winter time, the frozen water of quiltization can flow to the Windshield below by fitfull, the change speed of icing of quickening centre portion; Because the glass outer lower inside scribbles heating power silver slurry, and heat is made progress away, changes the ice of bottom and centre portion well.By ventilation slot turnover hot gas up and down, can eliminate outside window ice in the engine preheating after-acceleration, or avoid producing fog in the rainy day.
Adopt the wind shielding structure of technique scheme, good impact resistance, long service life, easy repairing, good processability have good in-use performance, also have characteristics in light weight, that cost is low simultaneously.
In sum, the present invention be a kind of impact resistance height, adiathermancy good, can produce separately or existing vehicle is reequiped, in the winter time can rapid frost except that Windshield, help improving the automobile wind shielding structure of vehicle safety.
