Title: Elastic filling for tyres, esp. for earth-moving machines, etc. - by filling air space with mixt. of poly:ol and isocyanate component which cures to form crosslinked PU elastomer
Inventor: GOMULKA GREGORZ
IPC: B29D30/04
Filed: 1989-06-22
Abstract: Process for prodn. of an elastic filling for vehicle tyres, esp. for highly-loaded tyres for earth moving machines, etc. involves filling the air space in the tyre with an elastomeric polyurethane material (I); (I) is produced from a polyol component (A) and an isocyanate component (B) which are kept separate beforehand and the mixed to form a 3-dimensionally crosslinked elastomer which cures inside the tyre. Tyres with an elastic filling of (I) are claimed as such. (A) comprises polyol(s), polyamine or amine mixt., process oil and catalyst, and (B) comprises polyisocyanate(s) and a process oil; polyol is also used in (B); a foam suppressant, e.g. silicone, is also added; polyamines or a mixt. thereof with alkanolamines are used as crosslinkers to form urea bonds during the reaction; polyols used are polyether-polyols with mol.wt. 400-6500, e.g.  diols, triols or tetrols, the catalyst is, e.g.  octoate, butyl-Sn mercaptol, Bu2Sn dilaurate, etc., and aromatic process oil (II) is used as extender. ADVANTAGE - The process extends the service life of heavy-duty tyres and minimises breakdowns; w.r.t. prior-art PUR-based tyre-filling processes, it avoids the use of water as crosslinker, uses less expensive raw materials and does not produce an elastomer with a high CO2 content.
