Description

Verfahren zur Aufbringung haftfester Beschichtungen aus Polyester-Harzen oder Epoxyd-Harzen auf Gegenstände aus Polyvinylchleridkunstharzen Es ist bekannt, Rohre, Behälter und dergelichen aus Polyvinylchlorid für chemisch beanspruchte Teile und Apparate ellizusetzen. @ierbei wirkt jedoch störend und die Einsatzfähigkeit behindernd, daß Polyvinylchlorid einen Erweichungspunkt um 60° C besitzt, dieser Stoff also nicht für Apparate elligesetzt werden kann, in denen Reaktionen bei höheren Temperaturen durchgeführt werden müssen. Es ist ferner bekannt, Kunstharzrohre und Behälter zum Zwecke einer mechanischen Verstärkung mit glasfaserverstärktem Polyesterharz oder Epoxydharz zu überziehen. Bei erhöhter Wärmebeanspruchung kann sich hierbei jedoch leicht die Beschichtung infolge der verschiedenartigen Wärmedehnung, mechanischer Beanspruchungen und dergleichen ablösen. Process for applying adhesive coatings made of polyester resins or epoxy resins on articles made of polyvinyl chloride synthetic resins It is known Pipes, containers and the like made of polyvinyl chloride for chemically stressed parts and apparatuses. @ierbei has a disruptive effect and the operational capability hindering that polyvinyl chloride has a softening point around 60 ° C, this Substance can therefore not be used for apparatus in which reactions at higher levels Temperatures need to be carried out. It is also known synthetic resin pipes and Container for the purpose of mechanical reinforcement with glass fiber reinforced polyester resin or epoxy resin to be coated. In the case of increased thermal stress, this can result however, the coating easily due to the various types of thermal expansion, more mechanical Replace stresses and the like.

Es wurde nun gefunden, daß dieser Nachteil vermieden und au#erdem der Einsatz von Polyvinylchlorid bei Behältern und Apparaten, die Temperaturen von tiber 60° a bis etwa 9100 a ausgesetzt werden müssen, ermöglicht werden kann, wenn man bei der Aufbringung haftfester Beschichtungen aus Polyesterha@sen oder Epoxydharzen, die glasfaserverstarkt sind, auf solcheii Rohren und Behaltern aus Polyvinylchloridkörpern nach dem Reinigen und schwachen Anlösen die Oberfläche des Polyvinylchlorids durch 2- bis 5-fachen Einstrich mit Styrol auflöst, darauf eine dünne Schicht von in Styrol gelöstem Polyester- oder Epoxydharzen aufbringt, diese Schicht angelieren läßt and dann erst die weiteren Beschichtungen mit glasfaserverstärktem Polyester- oder Epoxydharz in bekannter Weise durchführt.It has now been found that this disadvantage can be avoided and moreover the use of polyvinyl chloride in containers and apparatus that can withstand temperatures of must be exposed to over 60 ° a to about 9100 a, can be made possible if when applying adhesive coatings made of polyester hoses or Epoxy resins, which are glass fiber reinforced on such pipes and containers made of polyvinyl chloride bodies after cleaning and weakly dissolving the surface of the polyvinyl chloride Dissolves a 2 to 5-fold application of styrene, then a thin layer of in styrene applied dissolved polyester or epoxy resins, this layer can gel and then only the other coatings with glass fiber reinforced polyester or epoxy resin performs in a known manner.

Das Auflösen der gereinigten und angelösten Polyvinylchlorid-Oberfläche geschieht am besten in möglichst kurzer Zeit, aber so, daß ein intensives Anlösen des Polyvinylchlorids und Diffusion des Styrols in die Oberfläche erfolgt. Es soll damit bezweckt werden, daM beim Aufbringen der Harzgrundschicht noch unverändertes Styrol in der Polyvinylchloridoberfläche vorliegt, das dann mit beiden Kunstharzoberflächen beim Polymerisieren vernetzt. Die in bekannter Weise der Harzgrundschicht und den weiteren Ester- bzw. Epoxydharzen zugesetzten Härter und Beschleuniger wirken in entsprechender Weise auf das in die Polyvinylchloridoberfläche diffundiarte StyrolsDissolving the cleaned and loosened polyvinyl chloride surface It is best to do this in the shortest possible time, but in such a way that it dissolves intensively of the polyvinyl chloride and diffusion of the styrene into the surface takes place. It should The purpose of this is to ensure that the resin base layer is still unchanged when the resin base layer is applied Styrene is present in the polyvinyl chloride surface, which then with both synthetic resin surfaces cross-linked during polymerization. The in a known manner of the resin base layer and the Hardeners and accelerators added to other ester or epoxy resins act in correspondingly in the styrene diffused into the polyvinyl chloride surface
