alkyd resin manufacturing process flow diagram

Also advance blending of liquid oil and fat in said mixture enables stable progress of the esterification reaction between polyhydric alcohol and fatty acid. 0000100842 00000 n A reactor equipped with a thermometer, stirrer, heating device and a rectification column was charged with 89 parts of pentaerythritol, 30 parts of ethylene glycol and 546 parts of soybean oil, which were heated to 140° C. under stirring. Examples of tetra- or higher hydric alcohols useful in said alcohol mixture include diglycerine, triglycerine, pentaerythritol, dipentaerythritol and sorbitol. 0000001940 00000 n The blend ratio of the above fatty acid component is such that the oil length of the resulting alkyd resin should range 30-70%, preferably 40-60%, for imparting adequate drying property and physical properties of the dry, coated films of paint compositions in which the alkyd resin is blended. 0000097233 00000 n After adding this mixt ure mixed for 0000009623 00000 n trailer <<3534896DB91B4A2EBB8FA211B3D11E27>]>> startxref 0 %%EOF 227 0 obj <>stream Into the system 5.0 parts of litharge and 5.0 parts of zinc acetate, and subsequently 150 parts of regenerated polyethylene terephthalate (regenerated PET), were charged. WENDEROTH, LIND & PONACK, L.L.P. After raising the temperature to 180° C., dehydrating condensation reaction was conducted by raising the temperature to 240° C. over a period of 3 hours while removing water, to obtain an alkyd resin. With 196 parts each of the alkyd resin solutions as obtained in above Examples and Comparative Examples, 0.6 part of 5% cobalt naphthenate solution and 2.5 parts of 12% zirconium naphthenate solution were mixed to provide clear paints. Then the temperature was brought down to 180° C., and 150 parts of regenerated polyethylene terephthalate (regenerated PET) and 5.0 parts of zinc acetate were charged. At that time point the pentaerythritol was dissolved, into which 0.2 part of dibutyltin oxide was charged, followed by charging of 129 parts of terephthalic acid, raising the temperature to 230° C. and maintaining the same temperature for an hour. Fig.1: Flow Diagram Showing Number of Trips per Day of Operator Next the From-to-Matrix was developed from Fig.1 makin g use of the envisaged composi te movement articulated above. Words like ethylene dichloride and VCM are not typically used in daily conversation. 0000001596 00000 n The temperature was raised to 180° C., and thereafter to 240° C., consuming 3 hours while removing water. The temperature was brought down to 180° C. then, 207 parts of phthalic anhydride was charged, 50 parts of xylene was added for refluxing, and the temperature was raised to 180° C. 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. 0000012063 00000 n Subsequently the product was cooled and diluted by addition of 500 parts of mineral spirits, and an alkyd resin solution having about 62% of non-volatile content and having Gardner viscosity (25° C.) of YZ was obtained. 0000002263 00000 n Further conducting the dehydrating condensation reaction at 240° C., an alkyd resin was obtained, which was cooled and diluted with 610 parts of minral spirits to provide an alkyd resin solution having about 60% of non-volatile content.

It is also preferred to use the polybasic acid component and the fatty acid component at such ratios that the carboxyl equivalent numbers in the sum of the polybasic acid component and the fatty acid component per one hydroxyl equivalent in the alcohol mixture falls within a range of 0.8-1, in particular, 0.85-0.99, inter alia, 0.90-0.99, for obtaining favorable water resistance and physical properties of dry coating film formed by applying paint compositions containing said alkyd resin. Zaki Ahmad, in Principles of Corrosion Engineering and Corrosion Control, 2006Fundamentals of Coating Acrylic resin A synthetic resin formed from either the polymerization or co-polymerization of acrylic monomer. A process for producing an alkyd resin having an oil length of 30-70%, which is characterized by comprising dissolving polyester resin whose chief starting material is terephthalic acid and which has been recovered from waste materials and regenerated, in an alcohol mixture of tetra- or higher hydric alcohol with tri- or lower polyhydric alcohol, the weight ratio of the former/latter being within a range of … ) is more convenient, in respect of depolymerizability of regenerated PES are not subject to critical limitations, long...
