Abstract
The invention discloses a preparation method of an automobile bumper material. The preparation method includes the steps of 1, mixing 60 weight parts of PP (polypropylene), 15 weight parts of metallocene ethylene-hexenyl copolymers, 2 weight parts of aluminum powder, 7 weight parts of nano calcium carbonate and 1 weight part of antioxygen fully in a mixing machine to obtain a mixture A; 2, placing the mixture A in a mould, and cooling to form a protection baseplate; 3, melting manganese steel, deoxidizing, and bonding the deoxidized molten manganese steel with the protection baseplate obtained in the step 2 by electroplating so as to obtain an elastic metal layer; 4, spraying oil paint on the surface of the elastic metal layer obtained in the step 3, and cooling for 1-2 hours; 5, coating the metal plate surface with a high-temperature-resistant and corrosion-resistant protection layer after the oil paint is cooled, wherein the manganese steel comprises, by mass, 40-60 parts of steel, 20-30 parts of manganese, 1-5 parts of carbon, 1-2 parts of silicon and 1-2 parts of chrome, and the thickness of the protection layer is not less than 5mm. The preparation method of the automobile bumper material has the advantages that the reinforcing function and a protection function of the automobile bumper material are enhanced.
Description
Technical field
The invention belongs to technical field of automobile parts, more particularly to a kind of preparation method of automobile bumper material.
Background technology
China has become the big area of consumption of the first in the world of automobile, and annual auto output is being stepped up, with automobile
The increase of yield, client increasingly payes attention to for the security of automobile, and the bumper that current automobile is used adopts stainless height
Forge after strength steel or High Strength Steel casting and form, but in the case where its intensity ensures, toughness is not ensured that,
After its toughness is improved, the corresponding intensity of inevitable loss, if not only proof strength again after guarantee toughness if need in steel alloy
Composition adjust accordingly, its toughness and intensity are usually coordinated by the units for needing addition a large amount of expensive, then its cost can be significantly
Increase, therefore need a kind of advantage of lower cost of invention badly, intensity and toughness can meet the bumper of high security again.Both
The intensity that can guarantee that bumper keeps, and the appropriate energy-absorbing of energy.
The content of the invention
Goal of the invention：There is provided a kind of with preferably reinforcing function and protection in order to overcome the above-mentioned deficiencies of the prior art
The preparation method of the automobile bumper material of function.
Technical scheme：For solve above-mentioned technical problem, a kind of preparation method of automobile bumper material of the present invention,
Comprise the steps：
Step one：Calculate by weight, by 60 parts of PP, 15 parts of hexene copolymers of metallocene ethene one, 2 parts of aluminium powders, 7 parts
Nano-calcium carbonate, 1 part of antioxidant obtain mixture A after being sufficiently mixed in mixer；
Step 2：Mixture A is put into mould and is cooled into protecting base plate；
Step 3：By the manganese steel fusing for filling a prescription following,
The mass fraction of the manganese steel is as follows：Steel：40～60 parts, manganese：20～30 parts, carbon：1～5 part, silicon：1～2 part,
Chromium：1～2 part；
After manganese steel is melted and carry out deoxidation and then carry out plating bonding with the protection bottom obtained by step 2, form bullet
Property metal level；
Step 4：The elastic metallic layer surface obtained in step 3 carries out paint spraying, and cools down 1～2h；
Step 5：Metal sheet surface after paint cooling is coated into fire resistant anticorrosive protective layer, the thickness of the protective layer
Degree is not less than 5mm.The present invention can play more preferable stablizing effect by front bumper made by design multilayer material, pass through
Potassium steel metal level is set, because potassium steel has very high stability, while with very high wearability, be unlikely to deform, can
To prevent front bumper to be easily deformed, by arranging protective layer, can prevent from painting scratch and interior metal corrosion, play
Protective effect well.
Further, the mass fraction of the step 3 medium managese steel is as follows：Steel：30～58 parts, manganese：22～28 parts, carbon：2
～4 parts, silicon：1.2～1.5 parts, chromium：1.2～1.3 parts.
The present invention compared with prior art, has the advantages that：
The present invention can play more preferable stablizing effect, by arranging by front bumper made by design multilayer material
Potassium steel metal level, because potassium steel has very high stability, while with very high wearability, be unlikely to deform, can in case
Only front bumper is easily deformed, by arranging protective layer, can prevent from painting scratch and interior metal corrosion, play very well
Protective effect.
Specific embodiment
The present invention comprises the steps：
Comprise the steps：
Step one：Calculate by weight, by 60 parts of PP, 15 parts of hexene copolymers of metallocene ethene one, 2 parts of aluminium powders, 7 parts
Nano-calcium carbonate, 1 part of antioxidant obtain mixture A after being sufficiently mixed in mixer；
Step 2：Mixture A is put into mould and is cooled into protecting base plate；
Step 3：By the manganese steel fusing for filling a prescription following,
The mass fraction of the manganese steel is as follows：Steel：40～60 parts, manganese：20～30 parts, carbon：1～5 part, silicon：1～2 part,
Chromium：1～2 part；
After manganese steel is melted and carry out deoxidation and then carry out plating bonding with the protection bottom obtained by step 2, form bullet
Property metal level；
Step 4：The elastic metallic layer surface obtained in step 3 carries out paint spraying, and cools down 1～2h；
Step 5：Metal sheet surface after paint cooling is coated into fire resistant anticorrosive protective layer, the thickness of the protective layer
Degree is not less than 5mm.The present invention can play more preferable stablizing effect by front bumper made by design multilayer material, pass through
Potassium steel metal level is set, because potassium steel has very high stability, while with very high wearability, be unlikely to deform, can
To prevent front bumper to be easily deformed, by arranging protective layer, can prevent from painting scratch and interior metal corrosion, play
Protective effect well.
Further, the mass fraction of the step 3 medium managese steel is as follows：Steel：30～58 parts, manganese：22～28 parts, carbon：2
