Abstract:

A need arose to lay down a firm surface within a short time in adverse environments sufficient to support light truck or aircraft traffic. To accomplish this goal, a polyester glass mat was developed. Firstly, a glass mat is laid down over the ground surface next, a polyester resin is mixed with a catalyst and a promoter in the field further, this mixture is sprayed on the mat and allowed to cure. The promoter is composed of N,N-dimethyl-p-toluidine and a solution of vanadium III trineodecanoate which is soluble in hydrocarbons. The basic process to obtain the vanadium trineodecanoate is commenced by reacting or reducing vanadium pentoxide with a mixture of formic acid and hydrochloric acid. The resultant mixture is heated for a period of time after which neodecanoic acid, triethyl phosphate, paraformaldehyde, and xylene are added. This solution is azeotropically distilled to remove the aqueous phase while the vanadium III salts remain in the xylene. One object of this invention is a catalyst capable of use in water. A second object is a catalyst having a sufficiently long shelf-life. Another object is a catalyst which causes polyester resin to set in less than 15 minutes and fully cure within an hour.
