| titleOfInvention | Mould material binding agent system which cold-hardens with formation of polyurethane |
| abstract | This invention relates to a mould material binding agent system for the production of foundry mould parts. This binding agent system contains as components a solution of a phenol-containing polyol having at least two OH groups in the molecule and a polyisocyanate, optionally also in the form of a solution, having at least two NCO groups in the molecule, which react with one another to a cold-hardening binding agent with formation of polyurethane. According to the invention there is also added to the polyisocyanate component a chlorosilane, which for example may comprise one or more compounds of the group trimethyl chlorosilane, dimethyl dichlorosilane, methyl trichlorosilane, tetrachlorosilane, diethyl chlorosilane, vinyl trichlorosilane and diphenyl dichlorosilane. The added quantity is preferably 0.01-2% by wt. relative to the polyisocyanate component. By the invention a simply and economically producible binding agent is created, which combines high initial strength values of the mould parts with good sand life values of the mould material mixture. |
