Abstract
A kind of mud shield on cars that adopts thermoplastic plastic to constitute belongs to the general vehicle matching component.The present invention adds certain amount of foaming agent in thermoplastic plastic, by injection machine injection mo(u)lding and foaming, after cooling off mudwing.This mudwing has good rigidly, and cost is low, and is in light weight, and manufacture craft is simple, withstanding corrosion, characteristics such as long service life.
Description
A kind of mudguard for vehicle belongs to the general vehicle matching component, is applicable to both sides, front and back, the especially automobile of vehicle tyre.
Existing motor tire mudwing adopts ferrous material to make through the impact extrusion compression technology mostly, and is installed on the both sides, front and back of vehicle, work under bad environment during running, easy oxidized corrosion, thereby the life-span is short, and also ferrous material is pressed in the course of processing in impact extrusion, manufacture craft is complicated, and cost is also higher.In French Patent (FRP) (patent No. FR2281264), disclose a kind of fender that adopts thermoplastic plastic and aluminium sheet to combine, though it can improve corrosion stability, and intensity is also big, its complex manufacturing technology, cost is higher.
Purpose of the present invention is exactly in order to overcome the shortcoming of above-mentioned existence, and a kind of good rigidly is provided, and in light weight, cost is low, and manufacture craft is simple, withstanding corrosion, antiageing, the mudguard for vehicle of long service life and manufacture craft thereof.
The objective of the invention is to adopt following technical scheme to finish, adopt thermoplastic plastic and add certain amount of foaming agent, the weight ratio of its composition is 100: 0.5～1.5, through injection mo(u)lding and foaming, through cooling off after, discharge gas during owing to the foaming agent decomposes then, impel thermoplastic plastic to be doubled and redoubled in identical weight lower volume and rigidity, thereby unit weight is little, and cost is low, and rigidity is big.
The present invention also can adopt to add in foaming agent anti-ageing agent, to increase the weather resisting property of mudwing, increases the service life.
Below will the invention will be further described by embodiment.With foaming agent azo two formylamino acids, the auxiliary agent salicylic acid, and 1010, DSTP, ten triazines-5, four kinds of ageing resistant formula materials such as ZnO were by 1: 4: 0.5: 0.3: 0.5: 0.5 weight ratio mix, be blended into above-mentioned relatively weight ratio then and be in 100 the thermoplastic plastic, and whole mixtures are joined in the injection machine holding bin, the hot system that gives through machine gives the fusing of heat back, by injection machine the plastics of melted by heat are injected the product mold of the system of giving in advance again, the foaming of giving free rein to, after cooling off the mudwing product.Foaming agent among the present invention can also be 4.4 '-OBSH, or dinitroso penta methine tetramine.Auxiliary agent then can be a urea derivative.
The present invention compared with prior art has good rigidly, and cost is low, (its production cost be irony about 2/3), manufacture craft simple (single injection-molded), (its proportion is more than 1/16 of iron) in light weight, corrosion-resistant, anti-aging, good weatherability, the characteristics such as long service life.
Claims (2)
1, a kind of motor tire mudwing that adopts thermoplastic plastic to make is characterized in that in the described thermoplastic plastic adding that foaming agent, both weight proportions are arranged is 100: 0.5-1.5, and with the injection machine single injection-molded and foam after cooling off.
2, motor tire mudwing as claimed in claim 1 is characterized in that adding has ageing resistant in the described foaming agent.
