specific Embodiment 2

[0024] The technical solution of the present invention is: a special material for automobile bumper, comprising, in parts by mass, consisting of the following components:

[0025]

[0026] Using the above-mentioned materials, the molding method for making an automobile bumper specifically includes the following steps:

[0027] 1) Take out an appropriate proportion of the above raw materials, put them into a pulverizer, stir for 20 minutes, and fully pulverize;

[0028] 2) Put the pulverized material in step 1) into the box, and stir until evenly mixed while adding water;

[0029] 3) Put the uniformly mixed material into the drying box, dry for 30 minutes, remove the moisture, and get the bad material;

[0030] 4) Put the bad material into the barrel of the injection molding machine, and use the heating barrel to melt the PPE plastic in the injection molding machine;

[0031] 5) Take out the melted raw material and push it into the mold, and wait for molding to cool for 20...

Abstract

The invention provides a special material for an automobile bumper. The special material is prepared from the following ingredients in parts by mass: 30-50 parts of PPE plastics, 10-30 parts of toughening agent, 0.5-1 part of associating agent, 20-40 parts of filler, 1-4 parts of lubricant, 1-6 parts of antioxidant and 1-8 parts of dispersing aid, wherein the toughening agent is poe (8150); the associating agent is bismaleimide; the filler is talcum powder with the mesh size of 1,250 meshes; the lubricant is pe wax; the antioxidant is an antioxidant 1010; and the dispersing aid is a polyacrylic dispersing agent. The special material for the automobile bumper has the beneficial effects that the bumper material obtained by the formula has higher specific strength, and compared with the original glass-reinforced plastic, the weight is lower and the energy consumption is lowered; the impact absorption capacity is enhanced, and the automobile bumper has the advantages of high rigidity, high heat resistance, flame resistance, relatively high strength, excellent electric properties and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile bumper production, and in particular relates to a special material for automobile bumper and a manufacturing method thereof. Background technique [0002] Automobile bumper is a safety device that absorbs and slows down the external impact and protects the front and rear of the car body. Under normal circumstances, the bumper is exposed to the air, so the failure mode of the bumper is mainly corrosion, abrasion, cracking, aging and tarnish, etc. Wait. The existing bumper itself has a large weight and poor ability to absorb shocks. Contents of the invention [0003] The purpose of the present invention is to provide a special material for automobile bumper which is non-toxic, has enhanced ability to absorb impact, has low weight and reduces energy consumption. [0004] The technical solution of the present invention is: a kind of special material for automobile bumper, comprising in parts by...
