Embodiment 1

[0053] The method for synthesizing self-drying water-soluble alkyd resin with fatty acid methyl ester of the present invention utilizes fatty acid methyl ester produced from waste oil as a raw material to synthesize self-drying water-soluble alkyd resin, and the raw and auxiliary materials are 30% fatty acid methyl ester and 4% linoleic acid in mass percentage , pentaerythritol 8%, ethylene glycol 6%, terephthalic acid 16.4%, benzoic acid 3%, trimellitic anhydride 8%, organotin 0.8‰, slaked lime 0.15‰, triethylamine 4%, propylene glycol butyl ether 20.505% Preparation; the synthetic operation steps are as follows:

[0054] (1) Add fatty acid methyl esters to the reactor, preheat to 120-160°C, add slaked lime and continue heating;

[0055] (2) Add pentaerythritol when the temperature rises to 180-200°C, and continue to heat up;

[0056] (3) When the temperature reaches 230-240°C, keep it warm for 1-2 hours. After no methanol is evaporated, add linoleic acid, terephthalic acid,...

Embodiment 2

[0060] The method for synthesizing self-drying water-soluble alkyd resin with fatty acid methyl ester of the present invention utilizes fatty acid methyl ester produced from waste oil as a raw material to synthesize self-drying water-soluble alkyd resin, and the raw and auxiliary materials are 21% fatty acid methyl ester and 6% linoleic acid in mass percentage , pentaerythritol 9%, ethylene glycol 7%, terephthalic acid 17%, benzoic acid 4%, trimellitic anhydride 9%, organotin 1.4‰, slaked lime 0.2‰, triethylamine 5%, propylene glycol butyl ether 21.84% Preparation; Synthetic operation steps are the same as in Example 1.

Embodiment 3

[0062] The method for synthesizing self-drying water-soluble alkyd resin with fatty acid methyl ester of the present invention utilizes fatty acid methyl ester produced from waste oil as a raw material to synthesize self-drying water-soluble alkyd resin, and the raw and auxiliary materials are 36% fatty acid methyl ester and 4% linoleic acid in mass percentage , pentaerythritol 7%, ethylene glycol 5%, terephthalic acid 15%, benzoic acid 2%, trimellitic anhydride 7%, organotin 0.7‰, slaked lime 0.12‰, triethylamine 3%, propylene glycol butyl ether 20.918% Preparation; Synthetic operation steps are the same as in Example 1.

[0063] The above three examples adopt the same operation steps to prepare the self-drying water-soluble alkyd resin, prepare the coating with the same iron red antirust paint formula, and test according to the national standard system. The test results are compared in Table 3.

[0064] The self-drying water-soluble alkyd iron red antirust paint technical in...

Abstract

The invention discloses a method of compounding self-dry water soluble alkyd resin with fatty acid methyl ester. The method comprises the steps of adopting fatty acid methyl ester produced form waste grease as a main material, and preparing a material with fatty acid methyl ester, linoleic acid, pentaerythritol, ethylene glycol, terephthalic acid, benzoic acid, trimellitic anhydride, organic tin, slaked lime, triethylamine and propanediol butyl ether in a designed proportion; firstly putting fatty acid methyl ester into a reaction still, after conducting preheating to about 140 DEG C, adding slaked lime, adding pentaerythritol when the temperature is raised to about 190 DEG C, raising the temperature again to about 235 DEG C and keeping the temperature for 1.5 hours, adding linoleic acid, ethylene glycol, terephthalic acid, benzoic acid and organic tin when no methyl alcohol is steamed out, and then keeping the temperature at about 230 DEG C; lowering the temperature to 180 DEG C and adding trimellitic anhydride when acid value is smaller than 6, keeping the temperature at about 170 DEG C until the acid value and viscosity are qualified and then lowering the temperature to be lower than 100 DEG C, adding triethylamine and propanediol butyl ethe in sequence, and obtaining filtrate, namely the self-dry water soluble alkyd resin after filtering. According to the method of compounding self-dry water soluble alkyd resin with fatty acid methyl ester, the water soluble alkyd resin has the advantages of being low in manufacture cost, good in dryness and high in hardness.

Description

technical field [0001] The invention relates to a preparation method of a self-drying water-soluble alkyd resin, in particular to a method for synthesizing a self-drying water-soluble alkyd resin by using fatty acid methyl ester. Background technique [0002] With the rapid development of the economy, the ecological environment is deteriorating day by day, and the air quality is deteriorating due to smog and dust. People are paying more and more attention to environmental protection issues. In order to strengthen environmental protection, various countries have enacted environmental regulations to limit the emission of volatile organic compounds (VOC). At present, traditional solvent-based coatings contain about 50% organic solvents. During the production and construction of coatings, a large amount of VOC is emitted into the atmosphere, which directly endangers the health of humans and other organisms. Therefore, industrially developed countries have begun to develop a larg...
