Embodiment 1

[0025] A modified material for an automobile blower housing, wherein the material is composed of the following components by mass percentage:

[0026] 50% to 70% of copolymerized recycled materials, 25% to 30% of virgin materials, 4% to 8% of fillers, 5% to 10% of tougheners, 0.1% to 0.3% of synergistic auxiliary antioxidants, multi-component hindered phenolic anti-oxidants Oxygen agent 0.1% ~ 0.4%, compatibilizer 5% ~ 10%.

Embodiment 2

[0027] Embodiment 2: basically the same as Embodiment 1, its difference is:

[0028] A modified material for an automobile blower housing, wherein the material is composed of the following components by mass percentage:

[0029] 50% to 60% of copolymerized recycled materials, 25% to 28% of virgin materials, 4% to 6% of fillers, 5% to 7% of tougheners, 0.1% to 0.2% of synergistic auxiliary antioxidants, multi-component hindered phenolic anti-oxidants Oxygen agent 0.1% ~ 0.2%, compatibilizer 5% ~ 7%.

Embodiment 3

[0030] Embodiment 3: basically the same as Embodiment 2, the difference is:

[0031] A modified material for an automobile blower housing, wherein the material is composed of the following components by mass percentage:

[0032] 60%~70% of copolymerized recycled materials, 28%~30% of virgin materials, 6%~8% of fillers, 8%~10% of toughening agents, 0.2%~0.3% of synergistic auxiliary antioxidants, multi-component hindered phenol type anti-oxidants Oxygen agent 0.2% ~ 0.4%, compatibilizer 7% ~ 10%.

[0033] As preferably, in the embodiment of the present invention, the synergistic auxiliary antioxidant in the modified material of the automobile blower housing is triphosphite, and the multivariate hindered phenol type antioxidant is pentaerythritol ester; The effect of gas hydrolysis and the effect of anti-oxidation and anti-aging. When using, you should make full use of two or more antioxidants in combination, which can produce additive or synergistic advantages to obtain bette...
