Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to the PP/HDPE of resistance to xanthochromia plastics and preparation method thereof for a kind of automotive upholstery.
Background technology
Automotive upholstery, English name: Automotive Interior, mainly refer to that automotive interior reequips automobile product used, relate to the every aspect of automotive interior, such as glove box, automobile seat backboard, automobile elbow-board, automobile side plate, column guard board, door-plate, Automobile Dashboard, undertray, case for radio and central control station etc. is all automotive upholstery product.Automotive trim system is the important component part of body of a motor car, and the design effort amount of interior decoration system accounts for the more than 60% of car shape-designing workload, far surpasses car conour, is one of most important part of vehicle body.
In current technology, automotive upholstery adopts plastic material conventionally, but conventional plastic material is easy to xanthochromia, and illumination aging resisting performance is poor.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides the PP/HDPE of resistance to xanthochromia plastics for a kind of automotive upholstery, has good illumination aging resisting performance.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned automotive upholstery with the PP/HDPE of resistance to xanthochromia plastics.
The PP/HDPE of resistance to xanthochromia plastics for automotive upholstery, comprise the component of following weight parts: 80 parts of polypropylene, high density polyethylene(HDPE) 5-25 part, TPE resin 2-8 part, anti-yellowing change agent 0.5-1.5 part.
Described anti-yellowing change agent is tetramethylolmethane four (3-lauryl thiopropionate), 4, a kind of or its mixture in 4'-bis-(propyloxy phenyl base) pentanoic and four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
Preferably, described anti-yellowing change agent, component by following weight parts forms: tetramethylolmethane four (3-lauryl thiopropionate) 30-50 part, 4,4'-bis-(propyloxy phenyl base) pentanoic 10-30 part and four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester 30-50 part.
The present invention also provides the preparation method of above-mentioned automotive upholstery with the PP/HDPE of resistance to xanthochromia plastics: by proportioning, take each raw material, after mixing, melting mixing, extruding pelletization, obtain the PP/HDPE of resistance to xanthochromia plastics for described automotive upholstery.
Obviously, for improving other performances of product, can also add adaptively other auxiliary agents, as fire retardant, tinting material and static inhibitor etc. in the present invention.
Concrete, in the present invention: tetramethylolmethane four (3-lauryl thiopropionate), No. CAS: 29598-76-3.4,4'-bis-(propyloxy phenyl base) pentanoic, No. CAS: 10081-67-1.Four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester, No. CAS: 3050-88-2.
The PP/HDPE of resistance to xanthochromia plastics for automotive upholstery of the present invention, have good formability, mechanicalness and shock strength, also have good yellowing resistance energy simultaneously, and available Shooting Technique is made automotive upholstery.
Embodiment
Below in conjunction with embodiment, the invention will be further described.Polypropylene, the PP resin that the trade mark that Yanshan Petrochemical company produces is K7726H.High density polyethylene(HDPE), selects the HDPE resin of the trade mark JK910 of Korea S SK company.TPE resin, selecting du pont company's trade mark is 7246 TPE resin.
Embodiment 1-4
According to corresponding embodiment 1-4 data in table 1, take each raw material respectively.After mixing, melting mixing, extruding pelletization, obtain the PP/HDPE of resistance to xanthochromia plastics for described automotive upholstery.
Table 1: automotive upholstery is with the PP/HDPE of resistance to xanthochromia plastic formula list position: kilogram
Test case
Respectively the plastics of embodiment 1-4 are put into vulcanizer and be pressed into the sheet that thickness is 1mm, then pass through coldmoulding, cut into the sample strip of 2cm * 5cm.Press GB/T16422.2-1999 plastics laboratory light source exposure test method, be placed in xenon lamp and tan by the sun the proofing box of light xanthochromia and irradiate, then press GB2409-80 plastics yellowness index test method, survey its yellowness index, obtain its xanthochromia index △ YI as shown in table 2 below.
Table 2: plastics yellowing resistance test chart
| ? | Xanthochromia index △ YI (1000h) |
| Embodiment 1 | 0.38 |
| Embodiment 2 | 0.58 |
| Embodiment 3 | 0.49 |
| Embodiment 4 | 0.60 |
Xanthochromia index △ YI is an important indicator that characterizes photooxidative aging performance, and △ YI is less, represents that illumination aging resisting performance is better.
From table 2 test result, the automotive upholstery that embodiment 1-3 makes is all lower with the xanthochromia index of the PP/HDPE of resistance to xanthochromia plastics, there is certain anti-yellowing change effect, especially embodiment 1 is used tetramethylolmethane four (3-lauryl thiopropionate), 4, 4'-bis-(propyloxy phenyl base) pentanoic and four [β-(3, 5-di-tert-butyl-hydroxy phenyl) propionic acid] the composite anti-yellowing change agent of pentaerythritol ester, three's synergy, be compared to embodiment 2 and 3, in the situation that use the anti-yellowing change agent of equal consumption, xanthochromia index is lower, strengthened more significantly the yellowing resistance energy of automotive upholstery with the PP/HDPE of resistance to xanthochromia plastics.
