Description

STABILIZER COMPOSITIONS WITH LOW ZINC CONTENT FOR WINDOW PROFILES

The invention relates to a low-zinc composition for the stabilization of halogen-containing polymers, in particular polyvinyl chloride (PVC) _. Profile applications involving said satellizer 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, e.g. Polyvinyl chloride (PVC), when melt-formed, transforms into a polyene structure, eliminating hydrochloric acid and discoloring the polymer. In order to improve the thermostability of the polymer, it is common to incorporate metal carboxylates as stabilizers in the resin. However, since the incorporation of the stabilizers alone in a longer

Melt-molding process causes blackening of the polymer, 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 in almost all cases is the calcium salt of an organic acid (e.g., technical stearic acid,

CONFIRMATION COPY 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 combined with a magnesium salt to the above base ^"""or replaced by a magnesium salt.

However, the calcium or magnesium salt may be used in combination with zinc salts based on o.o. organic acids are used. 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 + 2 HCl - »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:

OOZ ^nCl 2 ⁺ Ca (O-R) ₂ * Zn (O-R) ₂ ^{+ CaCl} 2

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 amount as shown in Tab. 1. 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 make it possible to produce plastic profiles with good thermal and light stability ^" in combination with a good initial color." The light and weathering stability is attributed, among other things, to the presence of zinc compounds by the person skilled in the art, but zinc as well as lead, tin and sulfur become an element considered 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 stable 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 by providing a stabilizer composition with Zinc contents of 0.5 to 1.5% at a use rate <4.5 phr for PVC profiles.

^_ And ^"give profiles the parts and products made from it a very good initial color, excellent color retention and increased stability to the action of sunlight and artificial light and a better Nachhaitigkeitspotential.
