Claims13
A mixture for producing moulded articles from fibre mats containing:
- a) 20 to 45 wt. % of a powdered binder mixture, comprising
- a1) 30 to 90% wt. % of phenol resin and
- a2) 70 to 10 wt. % of powder coating waste, and
- b) 80 to 55 wt. % of organic and/or inorganic fibres,
- wherein the component a2) consists of powder coating waste which is not yet cross-linked, based on at least one member selected from the group consisting of epoxide, polyester, polyurethane and acrylate resins containing reactive groups.
A method of using powder coating waste which is not yet cross-linked, said waste being based on at least one member selected from the group consisting of epoxide, polyester, polyurethane and acrylate resins containing reactive groups comprising moulding articles from fibre mats using a mixture, as follows:
- a) 20 to 45 wt. % of a powdered binder mixture, comprising
- a1) 30 to 90% wt. % of phenol resin and
- a2) 70 to 10 wt. % of powder coating waste, and
- b) 80 to 55 wt. % of organic and/or inorganic fibres.
A method of using powder coating waste which is not yet cross-linked, said waste being based on at least one member selected from the group consisting of epoxide, polyester, polyurethane and/of acrylate resins, containing reactive groups,, comprising bonding fibre mats using a mixture, as follows:
- a) 20 to 45 wt. % of a powdered binder mixture, comprising
- a1) 30 to 90% wt. % of phenol resin and
- a2) 70 to 10 wt. % of powder coating waste, and
- b) 80 to 55 wt. % of organic and/or inorganic fibres.
