Abstract

Stabilizer composition for halogen-containing polymers with a Zn content of approx. 0.5 to approx. 1.5% zinc (based on the total amount of the stabilizer composition) when the stabilizer used is approx. 1 to 4.5 per 100 parts of resin.

Description

The invention relates to a low-zinc composition for stabilizing halogen-containing polymers, in particular polyvinyl chloride (PVC) profile applications, which include said stabilizer composition.

Halogen-containing polymers or plastics or molded articles produced therefrom tend to undergo substantial changes during their production process and due to the effect of environmental influences. For example, these types of plastics may decompose or discolor under the influence of heat and / or light. To stabilize halogen-containing polymers, therefore, a very wide variety of substances or mixtures have already been used.

A halogen-containing polymer, such as. As polyvinyl chloride (PVC), passes in the melt-forming in a polyene structure, wherein hydrochloric acid is eliminated and the polymer is discolored. In order to improve the thermostability of the polymer, it is common to incorporate metal carboxylates as stabilizers in the resin. However, since incorporation of the stabilizers alone causes blackening of the polymer in a longer melt molding process, it is common practice to add a co-stabilizer. There are a variety of combinations of inorganic and organic compounds known as stabilizers for halogen-containing polymers.

The basis forms in almost all cases the calcium salt of an organic acid (eg technical stearic acid, lauric acid, 2-ethylhexanoic acid, octanoic acid or benzoic acid). The calcium salt causes a fundamental stabilization of the halogen-containing polymer by the binding of the liberated hydrochloric acid as calcium chloride. The calcium salt is occasionally mixed with a magnesium salt to o. G. Base combined or replaced by a magnesium salt.

However, the calcium or magnesium salt can be used in combination with zinc salts based on the above-mentioned organic acids. On the one hand, the zinc salts having the formula 1 depicted above give the halogen-containing polymer a good color because they can substitute the labile chlorine atoms on the halogen-containing polymer (PVC). Zinc chloride is formed during this reaction. This chloride is known to the chemist as Lewis acids. It is capable of binding more than two chloride ions as shown in Formula 2. As a result, the chloride catalyzes the decomposition of the halogen-containing polymer and reduces the stability. Formula 1:

Formula 2:

• ZnCl ₂ + 2HCl → H ₂ [ZnCl ₄ ]

Another reaction of the alkaline earth metal soaps is the displacement of the fatty acid by hydrochloric acid from the salt as shown in Formula 3. Formula 3:

With different ratios of alkaline earth to zinc salts, all stabilities and initial colors can be adjusted in principle. If the alkaline-earth soap dominates, good stabilities can be achieved with a rather modest initial color. If zinc salts predominate, the color is better, with probably acceptable stability. From the formation of the zinc chloride according to formula 1 or formula 2, which promotes decomposition of the halogen-containing polymer, there is the need to use costabilizers. These costabilizers either bind hydrochloric acid or they complex the Lewis acids ie the zinc chloride in this case. typical Costabilizers are hydrotalcites, zeolites, metal (hydr) oxides, polyols, β-diketones, organic phosphites, antioxidants, epoxides, perchlorates etc.

Commercially available window profile stabilizers contain between 2.0 and 6.0% zinc at a stabilizer use level of about 3.5 to 4.5 per 100 parts resin (phr = per hundred resin). In the patent literature, comparable zinc contents for stabilizer combinations for PVC profiles can be found at a comparable use amount as shown in Tab. Zinc contents <2.0% can be found only at a significantly higher input quantity, which has significant cost disadvantages for the user. Such stabilizer combinations allow the production of plastic profiles with good thermal and light stability in combination with a good initial color. The good light and weathering stability is attributed by the person skilled in the art, inter alia, to the presence of zinc compounds. However, as well as lead, tin and sulfur, zinc is considered to be unsustainable in the literature ( C. Azar, J. Holmberg, K. Lindgren; "Socio-ecological indicators for sustainability" Ecological Economics 18 (1996) 89 ; KE Lunde, J. Leadbitter, M. Schiller; "Sustainability assessment of stabilizer systems for use in PVC pipes", PVC '05, Brighton, UK, 2005 ; Mark Everard; "PVC: Reaching for Sustainability" IOM3 and The Natural Step, 2008 ).

It would surprisingly be found that a PVC stabilizer composition has advantageous properties, particularly when using the composition for the plastic profiles, when the Zn content is limited within a very narrow range. Therefore, there is a need to provide stabilizer combinations that have the better properties than the usual stabilizer compositions.

This object has been achieved by the features of the composition according to claim 1.

The present invention is therefore based on the object of providing new low-zinc stabilizer compositions at a use amount <4.5 phr, which are particularly suitable for PVC profiles, without having the above-mentioned disadvantages of the known stabilizers.

This object is achieved according to the invention by the provision of a stabilizer composition with zinc contents of 0.5 to 1.5% with a use amount <4.5 phr for PVC profiles.

Surprisingly, it has been found that the stabilizer compositions according to the invention give PVC profiles and the parts and products made therefrom a very good initial color, excellent color retention and increased stability to the action of sunlight and artificial light and a better sustainability potential.

In particular, the initial color and the color retention of the halogen-containing material can be significantly improved compared to other organic and inorganic costabilizers when used in applications that are used outdoors, for example in profiles. In addition, it has been found that by using the stabilizer compositions according to the invention moldings of halogen-containing polymers can easily be produced which enable optimum performance in use and which are comparable to PVC stabilization commodities based on stabilizer compositions for PVC profiles. This stabilizing effect also occurs when the PVC contains further stabilizers, co-stabilizers or adjuvants.

Examples of such halogen-containing polymers may include thermoplastic halogen-containing polymers, for example, but not limited to, polyvinyl chloride (PVC), polyvinylidene chloride, chlorinated or chlorosulfonated polyethylene, chlorinated polypropylene or chlorinated ethylene / vinyl acetate copolymer or similar compounds. Particularly advantageous are polymers of the PVC type, d. H. Vinyl chloride homopolymers and copolymers of vinyl chloride with other monomers.

The stabilizer compositions for halogen-containing polymers according to the present invention contain at least one zinc compound. The stabilizer composition according to the present invention may be added in total in an amount of about 1 to 4.5 parts per 100 parts of resin (phr).

In one embodiment, the stabilizer composition is added in an amount of about 2.0 to 4.3 phr, for example, in an amount of about 2.5 to about 3.8.

The stabilizer composition used according to the invention can be added individually to the polymer or to the polymer mixture. However, it is also possible to add the combination according to the invention together with other (co) stabilizers or the auxiliaries listed below to the polymer or a polymer mixture.
