Description

[Technical Field]

[0001] The claimed invention relates to an additive mixture comprising a compound of formula (1) and a compound of formula (2). The claimed invention further relates to a composition comprising an organic material susceptible to oxidative, thermal, or photoinducible decomposition and the additive mixture. The claimed invention also relates to a method for stabilizing an organic material by incorporating or applying the additive mixture thereto. Furthermore, the claimed invention relates to the use of the additive mixture as a light stabilizer for an organic material. [Background technology]

[0002] Organic materials such as polyolefins, polyethylene, and polypropylene, i.e., synthetic polymers, are widely used in the manufacture of various extruded and molded articles due to their ease of use. However, these articles often suffer from general stability issues when repeatedly exposed to UV light. Furthermore, current stabilization systems, i.e., anti-scratch modified organic materials, when used to prepare automotive articles, result in blooming / seepage due to repeated exposure to UV light. Blooming / seepage is undesirable because it can destroy the aesthetic surface properties of articles manufactured using blooming polymers. Blooming is particularly undesirable in articles where transparency is desired. Blooming is also undesirable because it reduces the ability of articles manufactured using blooming polymers to be securely bonded to other articles by adhesives. Blooming is recognized as a serious problem in several applications, and effective means of mitigating it have been sought for many years. [Overview of the project] [Problems that the invention aims to solve]

[0003] Therefore, it is highly desirable to maintain properties such as polymer stability when exposed to UV light and to reduce the tendency of polymer blooming.

[0004] Therefore, an object of the present invention is to provide an additive mixture that stabilizes organic materials susceptible to oxidative, thermal, or photo-induced decomposition.

[0005] Another object of the present invention is to provide an additive mixture that, when used in organic materials, provides a surface that does not exhibit tackiness toward organic material articles and does not show blooming / leakage from organic material articles. [Means for solving the problem]

When used with organic materials, the additive mixtures of the claimed invention provide a surface that does not exhibit tackiness to organic material articles and does not exhibit blooming / leakage from organic material articles.

[0007] Therefore, in one embodiment, the claimed invention is a compound of formula (1) and a compound of formula (2). [ka] (In the formula, A1 is linear or branched, substituted or unsubstituted C1-C 20 It is alkyl, and A2 is linear or branched, substituted or unsubstituted C1-C 30 This relates to an additive mixture containing alkyl.

[0213] The following examples illustrate the present invention in more detail. All percentages and parts mentioned herein are by weight unless otherwise specified. [Examples]

[0214] Example 1: Stabilization of thermoplastic polypropylene Base formulation: 1. 89.36% by weight thermoplastic polypropylene (Daplen® EE013 AE of Borealis); melt flow rate: 11 g / 10 min (ISO 1133), density: 905 kg / m³ 3 (ISO 1183) 2. A blend of 0.1% by weight of 80% tris(2,4-di-tert-butylphenyl)phosphite + 20% octadecyl-3-[3,5-di-tert-butyl-4-hydroxyphenyl]propionate, 3. 0.05% by weight of calcium stearate, 4. 10.0% by weight of talc, 5. 0.03% by weight of carbon black, and 6. 0.4% by weight of ercamid.

[0215] Further additive mixtures, outlined below, are incorporated in the same manner as in the mixture and base formulation. In all cases, the weight percentage of thermoplastic polypropylene is adjusted so that the total of all components equals 100%.

[0216] Additive mixture: Compound A: 1,3,5-tri(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate, Compound B: 1-(2-hydroxy-2-methylpropoxy)-4-octadecanoyloxy-2,2,6,6-tetramethylpiperidine Compound C:N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N'-diformylhexamethylenediamine, and Compound D: A condensate of 1,6-hexanediamine and 2,4,6-trichloro-1,3,5-triazine, as well as N,N-dibutylamine and 4-butylamino-2,2,6,6-tetramethylpiperidine.

[0217] [Table 1]

[0218] Preparation of test specimens: The base formulation was pre-mixed in a Pappermaier® ESK-150 mixer. This mixture was combined with 0.6 wt% of the above additive mixture in a Mixaco Lab CM12 high-speed mixer and compounded at 220°C in a Bersterff® ZE 25x32D twin-screw extruder. Subsequently, injection molding was performed at 240°C in an Engel HL65 injection molding machine.

[0219] Injection-molded plaques measuring 40mm x 60mm x 2mm or 25mm x 60mm x 2mm were exposed to artificial weathering according to international standards from Volkswagen (VW), PV 1303-Grayscale and Volkswagen, PV 1303-Delta E. The PV 1303 settings are as follows: VW PV 1303, DIN 75 202: Lamp: Xenon arc Lamp illumination: 1.2W / m 2 @420nm or 300-400nm at 60W / m 2 Lamp filter set: Borosilicate inside / Soda lime outside Black panel temperature BPT: 100±3℃ Dry valve temperature: 65±3℃ Chamber RH: 20±10% Weather cycle: Permanent light / no dark period, dry only / no rain

[0220] The parameters measured were color shifts on a grayscale according to DIN EN ISO 105-A05 and a delta-E scale according to DIN 6174.

[0221] The results are shown in Tables 1 and 2.

[0222] [Table 2]

[0223] [Table 3]

[0224] Tables 1 and 2 clearly show that adding the additive mixture of the present invention better preserves the properties of the tested thermoplastic polypropylene sample (i.e., there is no color change due to decomposition when exposed to artificial weathering).

[0225] Example 2: Stabilization of thermoplastic polypropylene Test specimens were prepared in the same manner as described in Example 1 and exposed to artificial weathering according to international standards from Volkswagen, PV 3930-Grayscale and Volkswagen, PV 3930-Delta E (PV3930 is also known as the "Florida Test").

[0226] The settings of PV 3930 are as follows: VW PV 3930: Lamp: Xenon arc Lamp irradiance: 0.5 W / m 2 @340 nm Filter set around the lamp: Inner borosilicate / Outer borosilicate Black standard temperature BST: 65 ± 3 °C Driver valve temperature: 40 ± 3 °C R.H. inside the chamber: 70 ± 10% Weather cycle: 108 minutes of light and dry / 18 minutes of light and wet

[0227] The measured parameters were color shifts on the gray scale according to DIN EN ISO 105 - A05 and on the delta E scale according to DIN 6174.

[0228] The results are shown in Tables 3 and 4.

[0229]

Table 4

[0230]

Table 5

[0231] From Tables 3 and 4, it is clear that by adding the additive mixture of the present invention, the properties of the tested thermoplastic polypropylene samples are better retained (i.e., there is no color change due to decomposition when exposed to artificial weathering).

[0232] Example 3: Stabilization of Thermoplastic Polypropylene In some combinations of polymers, fillers, colorants, stabilizers, and anti-scratch agents, some of the additives may migrate, and in unfortunate combination ratios, these additives may even bloom on the surface. When exposed to sunlight and decomposed, these additives can form a sticky layer. A stickiness test can record how this stickiness develops on the surface.

[0233] Test specimens were prepared in the same manner as described in Example 1, and their tackiness was evaluated according to the international standards PV 1306-GS and PV 1306-DE (PV1306 is an exposure test for determining the tackiness of polypropylene parts). Finger-tactile tackiness was evaluated according to a predetermined system and recorded over the aging time. The evaluation system used for this test is as follows:

[0234] [Table 6]

[0235] The results are shown in Table 5.

[0236] [Table 7]

[0237] Table 5 clearly shows that by adding the additive mixture, a surface can be obtained that does not exhibit tackiness to the thermoplastic polypropylene sample and does not show blooming / exudation from the thermoplastic polypropylene sample.
