Hence, normally terephthalic acid is not used for alkyd resin production or, if used, in only minor amount. For accomplishing this, generally preferred use ratio of the polyester resin is 5-40%, in particular, 10-35%, inter alia, 10-30%, by weight, based on the total weight of the polyester resin, alcohol mixture, polybasic acid component and the fatty acid component.

The acceptable-sized strands are dried in either a conveyor or direct-wood fired rotary drum dryer and stored in a dry bin where they await Where they are used as resins for room temperature-curing type paints, the drying property can be still improved by concurrent use of metal compound dryers such as cobalt naphthenate, zirconium naphthenate, lead naphthenate and the like. In the production of alkyd resin, coloration of formed alkyd resin can be inhibited by adding to the depolymerization product of regenerated PES, in advance of the esterification reaction, a minor amount, e.g., 0.1-10 weight parts per 100 weight parts of said product, of a phosphorus compound. On the other hand, recently disposal of waste is becoming a serious issue and utilization of disused PET bottles by recycling is under study. In particular, drying or semi-drying oils having iodine values of at least 100 are preferred, inter alia, soybean oil and tall oil are advantageous. 0000002116 00000 n Into the system 5 parts of litharge and 5 parts of zinc acetate, and then 150 parts of regenerated polyethylene terephthalate (regenerated PET) were charged, and the temperature of the system was raised to 230° C. Maintaining the same temperature for 4 hours, an ester-interchange reaction of the soybean oil (alcoholysis) and depolymerization of the regenerated PET were simultaneously carried out. This esterification reaction can be conveniently carried out by any method known per se, in the presence of an esterification catalyst such as zinc acetate, litharge, dibutyltin oxide and the like. The painted plates were allowed to stand in a 20° C. and 60% RH room and the time required for the paint films to give dry touch and the cure-drying time were measured. As examples of the phosphorus compound, phosphoric acid, phosphorous acid and hypophosphorous acid; and alkyl esters or phenyl esters of these acids (e.g., trimethyl phosphite, trimethyl phosphate, triphenyl phosphite and triphenyl phosphate) may be named. A reactor similar to the one used in Example 8 was charged with 123 parts of pentaerythritol, 30 parts of ethylene glycol and 264 parts of soybean oil, which were heated to 140° C. under stirring.

Example 2 was repeated except that 2 parts of trimethyl phosphate was added after depolymerization of regenerated PET, to obtain an alkyd resin solution having 62% of non-volatile content and having Gardner viscosity (25° C.) of Y. The formaldehyde production cost is generally made for over the 80% by the raw material consumption, and therefore the methanol yield is the most important item to be considered. flow sheet of epoxy resin production process cnplin alkyd resin flow , epoxy resins process flow diagrams XSM is a leading global manufacturer of crushing and . A reactor equipped with a thermometer, stirrer, heating device and rectification column was charged with 109 parts of pentaerythritol and 107 parts of ethylene glycol, and their temperature was raised to 140° C. under stirring. However, this method is subject to a number of problems such that it requires advance synthesis of the alkyd resin oligomer, requires many hours for the depolymerization and filtration of ultimately obtained alkyd resin causes occurrence of large amount of filtration residue, because the amount of the alcohol component in the occasion of depolymerization is too low to sufficiently depolymerize the recovered polyester resin. Developed in the 1920s, alkyd-based enamel paints were once one of the most important types of surface coating. 0000111347 00000 n The temperature was raised to 230° C. and maintained at the same level for 2 hours to effect depolymerization of the regenerated PET. In said production of alkyd resin, coloring in the formed alkyd resin can be inhibited by adding to the depolymerization product of the regenerated PES a minor amount, e.g., 0.1-10 weight parts, of a phosphorus compound per 100 weight parts of said depolymerization product in advance. For example, a system composed of a depolymerization product of a polyester resin with an alcohol mixture, which is obtained as above-explained, to which the polybasic acid component and fatty acid component are added, is kept at temperatures from about 110° C. to about 260° C., preferably from about 150° C. to 250° C., for about 3 to 10 hours in the presence of an esterification catalyst, to be dehydrated and condensed. 4 3.

Thereafter the temperature was raised to 240° C. over a period of 3 hours while removing water, and the dehydration condensation reaction was conducted at said temperature to obtain an alkyd resin. Into the system 5.0 parts of litharge and 5.0 parts of zinc acetate were charged, the temperature was raised to 230° C. and the system was maintained at the same temperature for 2 hours. Thereafter the temperature was raised to 230° C., and the system was maintained at the same temperature for an hour to effect depolymerization of the regenerated PET.

As the polybasic acid component, those normally used as the acid component for forming alkyd resins can be similarly used. The resins, therefore, can be conveniently used also as resins for paints for the use where overcoatability is required. 0000024131 00000 n The painted plates were allowed to stand in a 20° C. and 60% RH room and the time required for the paint films to give dry touch and the cure-drying time were measured. and dibasic acid (or phthalic anhydride).
