Abstract
The invention discloses a kind of electric motor car ceiling processing technology, it comprise the following production steps that (1) by PIMC electrostatic spraying on mould, mold temperature controls between 130～160 DEG C, coating thickness 70 ± 2 μm, hardening time 20～30s；(2) being then laid on mould compressing by load weighted SMC sheet shape moulding compound, the press time (generally, often increases 1mm thickness according to product thickness different set, the calculating press time is about 40s in theory), take out product afterwards, setting tooling is shaped, inspection, warehouse-in.The technique of the present invention achieves Diamond Search discharge, solvent-free volatilization, and coating can be all of, alleviates the environmental protection pressure of enterprise.
Description
Technical field
The present invention relates to the ceiling of electric motor car, a kind of ceiling processing technology being applicable to box-type electric car.
Background technology
The car body lightweight trend of present electric motor car is main flow, and the technical approach of current automotive light weight technology mainly has 3 kinds:
One be structure member based on metal, utilize carbon fiber and composite to strengthen, can loss of weight 10% to 20%, this technology is
By a lot of cars, enterprise uses, and is also the light-weighted main method of conventional fuel oil car.Vehicle complete vehicle weight reduction 10%, fuel efficiency meeting
Improve 6～8%；Car weight often reduces 100 kilograms, and hundred kilometers of oil consumptions can reduce by 0.3～0.6 liter；Car weight often alleviates 100 kilograms, dioxy
Change carbon emission reduction 1600～2000 kilograms.
Two is that vehicle body upper portion uses the composites such as carbon fiber, and chassis is aluminium alloy structure, and this technology can make composite wood
Material proportion in complete automobile-used material is close to 50%, and weight loss effect reaches 30%.First electric motor car of BMW has used this technology.
Three is to use the combination of the multiple material such as metallic composite, and composite materials ratio is higher, weight loss effect up to
50%, representative vehicle be Dresden University Of Technology's lightweight and material technology institute, Germany Sachsen lightweight center and
Four electrocar InEco of Superlight that Di Sen-Krupp develops jointly.
The lightweight of vehicle body is not only by automobile, the lightweight of electric motor car, also comprises drive apparatus, battery etc..Such as increase
The battery capacity of unit volume, at present can through engineering approaches to this technology to realize lightweight.Answering of the electric motor car of some brand
Condensation material materials ratio reaches 57%, and transmission and battery system also achieve lightweight, and the total life cycle of this car can save energy 28%, with
Time bring be production line the degree of depth innovation.
Lightweight is inseparable with new material, and electric motor car lightweight will relate generally to 5 big materials future: the heat that carbon fiber is strengthened
The thermosets of plastic material, high strength steel, carbon fiber reinforcement, aluminium alloy, magnesium alloy.Use to these materials, Ying Cong
Cost and the connection of metal, repair and the aspect such as recovery carries out comprehensive consideration.Wherein, the sexual valence that polymer composite is current
The highest.
What the electric motor car ceiling produced now used is safety glass material mostly, but, safety glass is as electricity
Electrical automobile ceiling uses the percentage of damage having 1 ‰, situation about crushing once occurs, can cause driver and passenger in various degree
Harm.Therefore, exploitation light weight, high-strength material is imperative as electric automobile ceiling.
Summary of the invention
The electric motor car ceiling that the product quality that it is an object of the invention to provide a kind of rational technology, processes is high makes work
Skill.
The technical scheme is that, a kind of electric motor car ceiling processing technology, it is characterised in that: it includes that following production walks
Rapid: (1), by PIMC electrostatic spraying on mould, mold temperature controls between 130～160 DEG C, coating thickness 70 ± 2 μm, Gu
The change time 20～30s；(2) then load weighted SMC sheet shape moulding compound is laid on mould compressing, the press time according to
Product thickness different set (generally, often increases 1mm thickness, the calculating press time is about 40s in theory), takes afterwards
Go out product, setting tooling is shaped, inspection, warehouse-in.
The technique of the present invention achieves Diamond Search discharge, solvent-free volatilization, and coating can be all of, alleviates the ring of enterprise
Packing pressure.
PIMC coating one-shot forming, decreases production procedure, the generation of the quality problems during greatly reducing, and improves
The qualification rate of product.
The minimizing of the middle processing link of the present invention, thus production site, the input of labor wage all can decline.
The present invention can be completely covered the mould of any configuration of surface, and the external coating of complex part is easily reached.
The technique of the present invention uses as primary coat, it is not necessary to sealing of hole is polished, and selects PIMC to repaste dress liquid side as primary coat
Painting can obtain automotive grade appearance surfaces.
The technique of the present invention realizes an application can obtain more than 70 microns films, and solves that to there is not painting interlayer attached
Put forth effort the bad problem that comes off caused.
