| titleOfInvention | Method for preparing dmpa modified waterborne alkyd resin |
| abstract | The present invention discloses a method for producing a DMPA-modified aqueous alkyd resin, according to which 70-90 parts by weight of flax oil and 10-30 parts by weight of maleic anhydride are mixed at room temperature, the temperature is raised to 240-250 ° C, and the temperature is raised to 7-9 hours. Obtaining a first product by maintaining the temperature while; Mixing 30-40 parts by weight of soybean oil, 10-20 parts by weight of polyalcohol, and 0.005-0.01 parts by weight of potassium hydroxide to raise the temperature to 240-250 ° C. and maintain the temperature for 1-1.5 hours; The temperature of the reaction product obtained in step 2 was lowered to 170-190 ° C, 20-30 parts by weight of phthalic anhydride, 8-15 parts by weight of DMPA, and 5-10 parts by weight of benzoic acid were added, and the additionally added xylene was refluxed ( refluxing), raising the temperature to 170-190 ° C, maintaining the temperature for 0.5-1.5 hours, raising the temperature again to 200-210 ° C and maintaining the temperature for 6-8 hours to obtain a second product; And 40-60 parts by weight of butyl ether and the first product are mixed, the second product is added, the temperature is lowered to 95-105 ° C, and an amine neutralizer is added so that the pH value of the mixture is 8.5-9 to DMPA (dimethylol propionic acid) ; dimethylol propionic acid) to obtain a modified aqueous alkyd resin. The water-based alkyd resin according to the present invention is greatly improved in safety and eco-friendliness, clearly showing a safe and eco-friendly aspect. |
