Background technology
Along with the development of automotive technology and the continuous increase of recoverable amount, people increase day by day to the requirement of vehicle safety performance.From goers outside vehicle protection angle, (to comprise front windshield glass, car bonnet, headlight, bumper/spoiler, engine charge cover) in all vehicle external profile parts be the highest to the contact probability of pedestrian head and front windshield glass in true traffic accident; Protect angle from the passenger, one of Main Function of front windshield glass is to prevent that the passenger from dishing out in collision outside car; From vehicle structure crash-worthiness angle, the energy that front windshield glass makes whole automobile frame rigidity be guaranteed and absorption portion produces due to collision.Traditional front windshield glass is mainly by two-layer soda lime glass and middle PVB(polyvinyl butyral) thin layer pressing under High Temperature High Pressure forms.Although the PVB laminated windshield glass has the performances such as good light transmission, noise reduction, isolation ultraviolet ray, fail to provide actv. impact energy absorb and pedestrian protecting performance in automobile collision accident, its impact energy absorption power a little less than.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of effectively apparatus with shock absorbing, protect pedestrains safety and vehicle structure safety under multiple impact, the energy-absorbing response efficiency is energy-absorbing type automobile front windshield glass and preparation method thereof faster.
For achieving the above object, the present invention takes following technical scheme: a kind of energy-absorbing type automobile front windshield glass, it is characterized in that: it comprises glass outer, inner layer glass and interlayer, and four peripheries of described glass outer and inner layer glass are crooked camber structure after cutting, edging and washing drying all; The described interlayer of sandwiched between described glass outer and described inner layer glass, and by wind-lace, described four peripheries are encapsulated, hot pressing forms described energy-absorbing type automobile front windshield glass in autoclave; The structure of described interlayer is corresponding setting with described glass outer and inner layer glass.
The wind-lace of described four peripheral regions all adopts polymethyl methacrylate materials to make, and adopts nano-porous materials that each described wind-lace is fixed.
The periphery that is positioned at described energy-absorbing type automobile front windshield glass bottom is concave curve, and all the other described peripheries are convex curve, and the radian of described four peripheries is less than or equal to 5 °.
The thickness of described interlayer is 1.52mm, and described interlayer adopts nano-porous materials to make.
Described interlayer adopts ZSM-5 type zeolite to make.
Described glass outer and inner layer glass all adopt soda lime glass.
A kind of method for making that realizes above-mentioned energy-absorbing type automobile front windshield glass, its step is as follows: (1) puts into the pipe heater blowing air with nano-porous materials, carries out the oven dry of three hours under 600 ℃～1000 ℃ high temperature; (2) nano-porous materials after drying is put into spirit solvent, forms a kind of transparency emulsion; (3) be to place under the high pressure of 2kPa～6kPa after 24 hours at pressure with transparency emulsion, remove the solvable bubble in transparency emulsion, be made into interlayer; (4) with the periphery of glass outer and inner layer glass crooked camber after cutting, edging and washing drying; (5) interlayer is clipped between glass outer and inner layer glass, peripheral region adopts polymethyl methacrylate materials to encapsulate, and puts at last autoclave hot-forming.
In described step (2), the ratio of described nano-porous materials and described spirit solvent is 3:5, and the concentration of described spirit solvent is 5%～95%.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is due to the interlayer that adopts nano-porous materials as energy-absorbing type automobile front windshield glass, and the periphery of glass outer and inner layer glass is arcuate structure, therefore, improved the energy-absorbing effect of energy-absorbing type automobile front windshield glass of the present invention.2, the present invention makes because interlayer adopts nano-porous materials, and glass outer and inner layer glass all adopt simple glass to make, and glass is typical hard brittle material, can't absorb a large amount of impact energys, but can realize energy-absorbing by interlayer.Related experiment proof 1g nano-porous materials can absorb the energy that is about 100J, therefore only uses the 100g nano-porous materials just can absorb a standard adult fully at the kinetic energy that is accelerated to 60km/h speed.3, interlayer of the present invention adopts nano-porous materials, and it has very fast energy-absorbing response efficiency.Related experiment proved nano-porous materials to the speed of response of outside impact load 10～100 times than traditional energy-absorbing material (such as cellular material, soft material etc.).Therefore, the nano-porous materials that adopts of the present invention especially is fit to be applied to the pedestrian head protection in automobile collision procedure.4, interlayer of the present invention adopts nano-porous materials, and it can protect multiple impact.In pedestrian-automobile, two-wheel car-automobile collision accident, human body and automobile wind shield glass contact process are the multiple impacts processes.Nano-porous materials can carry out the energy-absorbing utilization of repetition, can reach in collision case the whole process protection effect to human body, and can greatly improve the Occupation coefficient after the front windshield glass collision.The present invention can be widely used in automotive field.
