Definitions
- the present invention relates to a method for stabilizing new thermoplastic synthetic material against oxidative, thermal and / or actinic degradation.
- the method according to the invention at least one polyphenol and at least one alditol and / or cyclitol are introduced into a new thermoplastic material.
- the process according to the invention can be used to stabilize new thermoplastic material with high effectiveness and in a very environmentally friendly and cost-effective manner against oxidative, thermal and / or actinic degradation.
- the present invention also relates to appropriately stabilized new thermoplastic synthetic material and to molding compositions and molded parts produced therefrom.
- the present invention also relates to stabilizer compositions and their use for stabilizing new thermoplastic plastic against oxidative, thermal and / or actinic degradation.
- Organic materials such as plastics are subject to aging processes, which ultimately lead to a loss of the desired properties, e.g. of the mechanical parameters.
- This process leads to changes in the polymer chain starting from radical chain splitting by mechanochemical processes or by UV radiation in the presence of oxygen, e.g. in molecular weight or the formation of new chemical groups.
- Stabilizers are therefore used to prevent or at least delay this aging.
- Important representatives of stabilizers are antioxidants, which interfere with the radicals formed in the autoxidation and thus interrupt the degradation process.
- primary antioxidants that can react directly with oxygen-containing free radicals or C radicals and secondary antioxidants that react with intermediate hydroperoxides (see C. Kröhnke et al.
- Typical representatives of primary antioxidants are, for example, phenolic antioxidants, amines but also lactones.
- Classes of secondary antioxidants are phosphorus compounds such as Phosphites and phosphonites, but also organosulfur compounds such as Sulfides and disulfides. In practice, primary and secondary antioxidants are usually combined, which leads to a synergistic effect.
- Plastics made from fossil raw materials such as petroleum or natural gas are increasingly being supplemented or replaced by plastics based on renewable raw materials, accessible through biochemical processes.
- the primary and secondary antioxidants used for this (and for plastics made from fossil raw materials) are still not entirely based on renewable raw materials.
- primary antioxidants from renewable raw materials are known, which are also used occasionally in plastics.
- a typical example is tocopherols (vitamin E).
- Tocopherols have the usual tioxidants have a sterically hindered phenol structure and can be used alone or in combination with secondary antioxidants (eg S. Al-Malaika, Macromol. Symp. 2001, 176, 107).
- Tocopherols can e.g. be isolated from natural substances such as wheat germ oil, sunflower oil or olive oil.
- secondary antioxidants, ie phosphite or phosphonite structures cannot be found in nature, so that synergistic combinations of primary and secondary antioxidants from renewable raw materials have so far hardly been accessible.
- a method for stabilizing new thermoplastic plastic against oxidative, thermal and / or actinic degradation is thus specified, in which at least one polyphenol (hereinafter also referred to as “component (A)”) and at least one alditol and / or cylitol (hereinafter also referred to as “components (B)”) is introduced into a new thermoplastic material.
- component (A) polyphenol
- components (B) alditol and / or cylitol
- the plastics to be stabilized can be based on fossil fuels Raw materials or made from renewable raw materials.
- New thermoplastic materials are not yet used, i. H. plastic material that has not yet been used.
- Corresponding new plastic material is also referred to in English as “virgin resin” or "pristine resin”.
- New plastics can also be called “new plastics” or “brand new plastics”.
- the new plastic material can be present, for example, as fresh plastic granulate or plastic powder, or also as a plastic melt that occurs during the manufacturing process. New plastic goods are therefore different from recycled plastics.
- plastic new goods In contrast to plastic recyclates, plastic new goods mostly show no or no significant pre-damage, ie there are no or only very minor new chemical groups on the polymer chain created by oxidative or (photo) oxidative processes.
- polyolefin recyclates for example, these are predominantly carbonyl groups, which are not present in new goods or are only present to a very minor extent.
- concentration of acid groups which are not or only to a minor extent found in new goods, while recyclates have a significant concentration.
- the concentration of the carbonyl groups is therefore also a measure of the pre-damage to the polymer.
- the concentration of carbonyl groups can be determined by known analytical methods such as infrared spectroscopy, as described, for example, in E. Richaud et al. Pole. Degr. Rod. 2009, 94, 410-420. Here, the absorption of the carbonyl vibration is measured in the range of 1720 cm 1 . In the case of new goods, the concentration of carbonyl groups is generally below 5 mmol / kg, the concentration of acid groups below 2 mmol / kg.
- the at least one polyphenol (component (A)) and the at least one alditol or cyclitol (component nente (B)) introduced into a new thermoplastic material.
- Components (A) and (B) can be introduced into the new plastic material individually or separately from one another, or components (A) and (B) can be put together in the form of a composition or composition containing components (A) and (B) are introduced into the new plastic material in the form of a composition consisting of components (A) and (B).
- components (A) and (B) consist of a renewable raw material.
- components (A) and (B), which may be in the form of powder, compact, granules, liquid, syrup, solution or flakes, are mixed with the new polymer to be stabilized, the polymer matrix is converted into the melt and then cooled.
- an additive which is solid at room temperature in a molten state into a polymer melt.
- components (A) and (B) can be in the form of so-called masterbatches or concentrates, which, for example, 10-90% of a stabilizer composition consisting of components (A) and (B) in a polymer or oligomer such as a polyethylene wax, Contain polypropylene wax or a natural vegetable wax, manufactured and introduced.
- a stabilizer composition consisting of components (A) and (B) in a polymer or oligomer such as a polyethylene wax, Contain polypropylene wax or a natural vegetable wax, manufactured and introduced.
- Components (A) and (B) can be introduced into the new thermoplastic material by mixing components (A) and (B) with the new thermoplastic material as a solid, and the resulting mixture is melted and then cooled.
- component (A) and component (B) used according to the invention act together as a synergistic stabilizer for the new thermoplastic material, the oxidative, thermal and / or actinic degradation of the new thermoplastic material being inhibited or prevented.
- component (A) and additionally component (B) into the new thermoplastic material, the Plastic stabilized against oxidative, thermal and / or actinic degradation.
- the present invention is particularly characterized in that a combination of polyphenols and alditols (sugar alcohols) and / or cyclitols is used to stabilize new thermoplastic materials.
- sugar alcohols and polyols are merely components in formulations for the heat stabilization of polyvinyl chloride (PVC) and other halogen-containing polymers such as polyvinylidene chloride (PVDC) in compositions which contain metal soaps as heat stabilizers.
- PVC polyvinyl chloride
- PVDC polyvinylidene chloride
- This stabilizing effect of polyols in halogen-containing polymers is explained by the fact that the zinc compounds which promote PVC degradation are chelated and deactivated (see HO Wirth, H. Andreas, Pure Appl. Chem. 1977, 49, 627-648 ; T. lida, K. Goto, J. Appl. Pol. Sci. 1980, 25, 887-900) or in order to achieve a reaction as an HCI scavenger in Zn-free PVC (see J. Steenwijk et al. Pol. Degr. Stab. 2006, 2233-2240).
- the introduction of at least one polyphenol and at least one alditol and / or at least one cyclitol alone and optionally together with at least one further primary and / or at least one secondary antioxidant is a very effective one Stabilization of new thermoplastic material against oxidative, thermal and / or actinic degradation can be achieved.
- both polyphenols and alditols or cyclitols are very environmentally friendly and inexpensive compounds. The process according to the invention can thus be used to stabilize new thermoplastic plastics in a very effective, environmentally friendly and cost-effective manner against oxidative, thermal and / or actinic degradation.
