Definitions
- the present invention is concerned with top layer resins.
- the top layer resin so that the finished part can be easily removed from the mold. Furthermore, it is desirable not only to have a high-gloss and resistant surface in the finished product. Often, especially in the case of glass fiber reinforced plastics (GRP), however, the surface properties such as the wetting behavior against grease and / or water, the ability to be cleaned, etc., leave much to be desired. Although it is possible in principle to achieve the desired surface properties by means of separate coating steps or the like, this possibility is often ruled out for cost reasons.
- GRP glass fiber reinforced plastics
- the object of the present invention is to provide something new for commercial use.
- a first essential aspect of the invention therefore consists in the proposal that at least 1% by weight of at least partially fluorinated monomers is contained in a cover layer resin.
- Cover layer can be obtained which has excellent surface properties such as non-stick behavior against water and 01 and yet does not lead to delamination or other impairment of the connection stability between the cover layer and other resin layers lying inside and the like.
- fluorochemical additives are effective additives in film-forming coatings, adhesives and
- sealing compounds and that such compounds can be added to a coating in small quantities as additives, in order to improve cleaning and bonding of the product properties such as oil / dirt and / or water repellency;
- the additional amounts proposed there should remain low at less than 1%, since thanks to the enrichment of the fluorine compounds at the air / substrate interface, small additional amounts should be sufficient to provide a fluorine-like surface. to create flat ones without negatively influencing the mass properties.
- the monomers can have a length of the at least partially fluorinated residue of at least 4 C atoms, preferably at least 6 C atoms, particularly preferably at least 8 C atoms. These lengths are preferred to ensure that there are sufficient fluorine atoms.
- the monomers can comprise at least one functional group which is selected from acrylates, methacrylates, carboxylic acids, amines, alcohols and / or mercaptans.
- the monomers are preferably adapted to the resin to be used in each case.
- At least essential parts and preferably all monomers consist of a fully or partially fluorinated radical and only one functional group.
- the top layer resin is structurally viscous, i.e. thixotropic and / or gel-like after application.
- the mass transfer is possibly made more difficult after annealing, which initially makes further enrichment of the fluorine compounds on the inner surface difficult.
- the shear liquid that arises again when the full resins are poured in may then be achieved.
- fluoride compounds that have already accumulated can possibly get into the full resins.
- a base layer resin base substance based on polyester facilitates preferred gelling and provides the desired thixotropy.
- Protection is also claimed for a method for producing a resin cover layer, wherein a cover layer resin is mixed with amounts of at least 1% by weight of at least partially fluorinated monomers and is used to produce the resin cover layer.
- the resins described can be used for a large number of different applications, owing to their multitude of positive properties, such as non-stick properties against water and oil, improved thermal resistance, and reduced surface friction in moving media, e.g. for all types of GRP materials, such as gliders, yachts, surfboards, vehicle bodies, wind turbines, etc.
- GRP materials such as gliders, yachts, surfboards, vehicle bodies, wind turbines, etc.
- mineral additives a mineral casting made of e.g. highly filled polyester can be obtained, which after hardening resembles a ceramic material and can be used in particular for the sanitary area such as wash basins, bathtubs, shower trays, toilet bowls, tiles, etc.
- Example 1 The invention is illustrated below by means of examples in a non-limiting manner.
- Example 1 The invention is illustrated below by means of examples in a non-limiting manner.
- 900 g of a polyester gel coat (eg "Norpol NGA” type) are intimately mixed with 100 g of a fluorinated acrylate (eg 3M FX-189 or Zonyl TM, Zonyl TA-N) with intensive stirring.
- a fluorinated acrylate eg 3M FX-189 or Zonyl TM, Zonyl TA-N
- 2% starter is added to the mixture obtained (eg MEKP) and applied to a metal mold with a release agent in a layer thickness of approximately 500 ⁇ m with a conventional spray gun
- a polyester filler resin is applied (eg Norpol 44M-97) according to the manufacturer, mixed with a starter and poured onto the hardened gelcoat, after 2 hours the mold is removed and the surface is cleaned with a mild cleaning agent if necessary.
- the molded body obtained shows water and dirt-repellent properties.
- the contact angle to water is approx. 85 °.
- the adhesion between the gelcoat and filler resin is checked with a cross cut / wallpaper test (DIN) and rated as 0/0 as excellent.
- a polyester gelcoat eg type "Norpol NGA"
- starter eg MEKP
- MEKP 2% starter
- a polyester filler resin e.g. Norpol 44M-97
- the adhesion between gelcoat and full resin is checked with a cross cut / wallpaper test (DIN) and also rated 0/0.
- the contact angle to water is approx. 65 °.
- Example 2 The procedure is as in Example 1, except that 40% by mass of inorganic fillers in the form of sand, clays and / or silica are added to the full resin. The result is a molded body with increased hardness and density with water and dirt-repellent behavior.
- Norpol NGA polyester resin 900 g is mixed intensively with 100 g of Zonyl TM fluoroalkylacrylate (DuPont). Then 2% by mass of MEKP (methyl ethyl ketone peroxide) is added to the mixture and placed on a metal mold in a layer thickness of approx. 500 ⁇ m sprayed on. After approx. 20 minutes, glass fiber fabric soaked with polyester laminating resin (Synolite 0035-Nl) is laminated onto the gel coat. Within approx. The composite is cured for 3 hours and can be removed from the mold. The result is a GRP component with a water- and dirt-repellent surface, in which the gelcoat layer can no longer be detached from the GRP.
- MEKP methyl ethyl ketone peroxide
- acrylate potting compound from Silikal
- fluoroalkyl acrylate from DuPont
- the contact angle with water is approx. 89 °.
