Definitions
- the invention relates to plastisol systems with improved adhesion and lower water absorption.
- Piastisols are generally understood to mean dispersions of finely divided plastic powders in plasticizers which gel when heated to higher temperatures, i. Harden.
- the plastisols or organosols thus obtained are used for a variety of purposes, in particular as a sealant and sound insulation, as a motor vehicle underbody protection, as corrosion protection coatings for metals, as a coating of sheet metal strips (coil coating), for impregnating and coating substrates made of textile materials and Paper (including, for example, carpet backing coatings), as floor coatings, as finishing compounds for floor coatings, for artificial leather, as cable insulation and much more.
- plastisols An important application of plastisols is the protection of body panels on the underbody of motor vehicles against stone chipping. In this application, particularly high demands are placed on the plastisol pastes and the gelled films. Naturally, a high mechanical resistance to abrasion caused by rockfall is essential. Furthermore, as long as possible usability of plastisol pastes (storage stability) is also essential in the automotive industry.
- the plastisol pastes must not tend to absorb water, because before the gelation absorbed water evaporates at high temperatures during gelation and leads to undesirable bubble formation. Furthermore, the plastisol films have a good adhesion to the substrate (usually KTL sheet), which is not only an important prerequisite for the abrasion properties, but also essential for corrosion protection.
- PVC polyvinyl chloride
- Piastisols based on PVC show good properties and are also relatively cheap, which is the main reason for their still widespread use.
- DE 4130834 describes a plastisol system with improved adhesion to cataphoresis sheet based on polyacrylic (meth) acrylates, wherein the binder contains an acid anhydride in addition to monomers having an alkyl substituent of 2-12 carbon atoms.
- adhesion promoters are blocked isocyanates, which are mostly used in conjunction with amine derivatives as curing agents (examples mentioned may be EP 214495, DE 3442646, DE 3913807).
- the object was to provide poly (meth) acrylate plastisols with good adhesion.
- the measure to improve the adhesion should be able to be applied in parallel with the methods already used so that it can be used immediately without the development of new formulations.
- the task was to reduce the water absorption of the ungelled Plastisolpaste.

- the amount of initiator is generally from 0.01 to 0.5 wt.%, Based on the polymer.
- the polymerization temperature depends within certain limits on the initiators. When using APS, it is advantageous to work in the range from 60 to 90 ° C. When redox systems are used, it is also possible to polymerize at lower temperatures, for example at 30 ° C.
- feed polymerization can also be carried out by the process of batch polymerization.
- the total amount or a proportion of the monomers is initially charged with all auxiliaries and the polymerization is started.
- the monomer-water ratio must be adapted to the released heat of reaction. In general, no difficulties arise when a 50% emulsion is produced by first emulsifying the adhesion of the monomers and the auxiliaries in the total amount of water and then initiating the polymerization at room temperature and after the reaction has cooled the mixture and added the remaining adhesion of the monomers together with the excipients.
