Description

Plastic sheet or plastic film

The present invention relates to a plastic sheet or plastic film consisting of one or more layers, in particular a flexible thermoformable plastic sheet or flexible deep-drawing film, consisting of 90 - 25 wt. %, preferably 85 - 28 wt. %, of a vinyl chloride homo-, co-, graft polymer and/or an alloy or mixture based on polyvinyl chloride, 10 - 75 wt. %, preferably 15 - 72 wt. % (based on 100 wt. % of the plastic mixture or alloy without additives, fillers, stabilizers, processing aids), of at least one modifier with a glass transition temperature of greater than 70 ^° C, preferably greater than 80 ^° C, and/or at least one modifier and a glass transition temperature of less than 60 ^° C, preferably less than 50 ^° C, and additionally at least one stabilizer or stabilizer mixture and optionally fillers, Antioxidants, plasticizers, lubricants, processing aids, dyes or color pigments, flame retardants or other additives or mixtures of one or more of these substances.

Moulding compounds with improved processing properties and ageing-resistant plastic films made from them are already known from DE-OS 3 3^2 435 and DE-OS 3 517 583. However, when exposed to strong light and high temperatures, heat and light ageing, colour changes and the like can also occur in these plastic films.

ff· ■ » ·

It is also known from DE-OS 1 469 886 to use metal stabilizers of 1 to 30 % calcium carbonate for polyvinyl chloride in order to obtain impact-resistant molded articles. However, if metal stabilizers are added to the molding compound in combination with calcium carbonate according to DE-OS 3 342 435 or DE-OS 3 517 583, it is not possible to achieve an improvement in the properties, in particular the ageing resistance when exposed to heat and light, especially at high temperatures, color changes, etc.

The aim and purpose of the present invention was to improve the properties, preferably aging stability, in particular heat and light aging of the aforementioned plastics even at higher surface temperatures. An improvement in color fastness when exposed to light and at higher temperatures should also be achieved.

According to the invention, it has been found that these aims and objects are met by a plastic sheet or plastic film consisting of one or more layers, in particular a flexible thermoformable plastic sheet or flexible deep-drawing film, which consists of 90 wt.%, preferably 85 - 28 wt. %, of a vinyl chloride homo-, co-, graft polymer and/or an alloy or mixture based on polyvinyl chloride, 10 - 75 wt. %, preferably 15 - 72 wt.% (based on 100 wt.% of the plastic mixture or alloy without additives, fillers, stabilizers, processing aids), at least one modifier with a glass transition temperature of greater than 70 ⁰ C, preferably greater than 80 ⁰ C, and/or at least one modifier and

a glass transition temperature of less than 60 ^° C, preferably less than 50 ^° C, and additionally at least one stabilising agent or stabilising agent mixture and optionally fillers, antioxidants, plasticisers, lubricants, processing aids, dyes or colour pigments, flame retardants or other additives or mixtures of one or more of these substances. According to the invention, the stabilizing agent consists of 1-10 parts by weight, preferably 2-8 parts by weight, of at least one stabilizer or stabilizer mixture based on an inorganic-chemical and/or organic-chemical lead and/or tin compound, preferably based on a tribasic lead sulfate, 4-basic lead sulfate, 2-basic lead phosphite, polybasic lead phosphite sulfide, 2-basic lead phthalate, an organotin compound containing at least one alkyl group, an oxygen atom and/or sulfur, an alkyl or dialkyltin compound which preferably contains an alkyl radical of Cty - Qq _f or an organotin compound or an organic-chemical group and/or tin bound via sulfur or oxygen and/or an alkyltin carboxylate compound and 0.1 - 10 Parts by weight, preferably 1-9 parts by weight, of a costabilizing agent or costabilizing agent mixture based on a magnesium or magnesium-aluminum compound, preferably based on a magnesium and/or magnesium-aluminum compound containing oxygen, CO2 or carboxylic acid and/or hydroxy groups.

Surprisingly, it was found that in plastic sheets or plastic films of the above-mentioned composition with the stabilizing agent mixture (including co-stabilizing agent), not only is the thermal stability improved, but also the color stability upon exposure and the drop in elongation at break, especially at high surface temperatures, are significantly positively influenced. The invention further relates to the above-mentioned composition as a ready-to-use plastic molding compound.

These improvements are particularly striking when a plasticizing polymer, e.g. ethylene-vinyl acetate copolymer, ethylene-vinyl acetate-carbon monoxide terpolymer and/or chlorinated polyethylene, etc., which, without additives, discolor significantly or quickly lose elongation at break, is used as a modifier.

According to a preferred embodiment, the plastic sheet or plastic film contains, for every 100 parts by weight of the plastic mixture (1 and 2), an additional 0.1 - 50 parts by weight, preferably 5-30 parts by weight, of an external plasticizer or plasticizer mixture, preferably based on an aliphatic and/or aromatic polycarboxylic acid ester, polymeric carboxylic acid ester and/or epoxidized natural oil, as well as at least one stabilizing and co-stabilizing agent.
