The invention relates to a process for the treatment of plastic surfaces, in which a surface of a coating or of a shaped body containing at least one halogen-containing plastic is treated with a composition containing at least one liquid carrier medium and additionally at least one polymer or at least one wax or both and the use of such a composition.

Description

The The present invention relates to a method for the treatment of Plastic surfaces, where a surface a coating or a shaped body, the at least one contains halogen-containing plastic, is treated with a composition containing at least one liquid carrier medium and additionally at least one curable one Monomer, a polymer, or at least one wax, or both, one Composition with which the method according to the invention are carried out as well as the use of such a composition.

coatings and shaped bodies made of plastics are due to their simple production, their chemical Properties as well as their essentially any formability can not think away from many areas of life. Especially the chemical properties of plastics are considered their resistance to environmental influences in many areas. Especially in applications requiring high surface resistance or objects across from the ambient conditions, for example in the food industry or in outdoor applications, require plastics are due to the above properties usually the suitable material.

Under There are many different types of plastics design options with regard to the production of surface coatings and moldings. When particularly inert to environmental influences However, in the past, the halogenated plastics have been found. So show surface coatings and shaped bodies, which are made of halogenated plastics or at least have a content of such halogenated plastics, in usually excellent manufacturing properties of surface coatings and moldings and above In addition, what the durability and mechanical strength of Plastics, an excellent weathering behavior.

It However, it is known that the color of the surfaces of objects containing halogens Contain plastics or exclusively from such plastics exist, in some cases through environmental influences like heat, cold, artificial Lighting, sunlight, rain, snow, humidity, solvents, Cleaning agents and the like may be subject to change. Especially for objects exposed to strong weather conditions are, for example, window frames or garden furniture, can such a color change to lead, that the corresponding objects exchanged for aesthetic reasons Need to become.

Especially for firmly anchored objects, such as window frames or door frame, This can lead to high costs. From the prior art, therefore, various attempts are known such surfaces to an aesthetic due condition.

So For example, it is sometimes suggested that a white surface restore, that the corresponding, discolored surface with a white one Topcoat coated becomes. Such a solution However, given the associated costs and the changed surface structure the plastic surface not optimal. About that In addition, such topcoats often already after a relatively short time already detachments from the underground, the surface an irregular appearance to lend.

The WO 03/025050 describes a method for the treatment of objects, which contain PVC. For the removal of discoloration it is proposed the surface to treat with a composition containing an organic solvent and a peroxide. To follow discoloration However, it must be sufficiently avoided in a subsequent one Step a UV absorber are applied. Apart from the fact that only the number of cleaning steps the Procedure very expensive designed, the processing of the surface must be very uniform, otherwise an irregular color distribution results.

It There was therefore a need after a process for the treatment of surfaces of objects or Moldings, the at least proportionally at least one halogen-containing polymer contain. In particular, there was a need for a method to treat such surfaces, simply and with as much as possible few work steps feasible is. Furthermore, there was a need according to a method of treating such surfaces, the to one as possible uniform distance of discoloration leads. About that There was also a need according to a composition with which the present method carry out leaves.

Of the Invention is therefore the object of a method and a Composition available with at least one of the above needs solved becomes. In particular, the present invention was based on the object, a method for treating surfaces of objects or Moldings, the at least one halogen-containing polymer contained th available put that one as possible even distance of discoloration allowed and with as possible few steps.

As "onium salt" is used in the context of present text denotes a compound which is an ammonium, Represents sulfonium or phosphonium salt. In an "onium salt" according to the present invention Invention is an organic onium salt. This means that the ammonium, sulfonium or phosphonium group of the onium salt carries at least one organic radical. An onium salt according to the present invention Invention may, depending on the nature of the onium group, 1, 2, 3 or 4 organic radicals carry. The organic radicals can thereby for example about a C-X link, where X is for S, N or P may be linked to the onium radical.
