Alkyd Resin Production Line

1.Introduction to Alkyd Resin
Alkyd resins are polyester-based polymers modified with fatty acids (often from vegetable oils). They are widely used as binders in:
-
Paints & Coatings (architectural, industrial, marine)
-
Printing Inks
-
Adhesives & Sealants
-
Wood Finishes
Alkyd resins offer excellent gloss retention, durability, and brushability, making them ideal for protective and decorative coatings. They can be classified as:
-
Short-oil alkyds (<45% oil content) - faster drying, harder films
-
Medium-oil alkyds (45-55% oil content) - balanced properties
-
Long-oil alkyds (>55% oil content) - slower drying, more flexible
2.Production Process of Alkyd Resin
1. Charging Raw Materials
-
Polyols (glycerol, pentaerythritol), dibasic acids (phthalic anhydride, isophthalic acid), and fatty acids/oils (soybean, linseed, coconut) are loaded into a stainless steel reactor.
-
The reactor is equipped with agitator, heating/cooling system, and condenser.
2. Alcoholysis (for oil-based alkyds)
-
If using vegetable oils instead of fatty acids, alcoholysis is performed first:
-
Oils + polyol (glycerol) → monoglycerides (at 220-250°C with catalyst like LiOH).
-
Reaction monitored by methanol solubility test.
-
3. Esterification (Polycondensation)
-
Dibasic acid (e.g., phthalic anhydride) is added.
-
Heated to 200-250°C under inert gas (N₂/CO₂) to prevent oxidation.
-
Water byproduct is removed via azeotropic distillation (xylene often used as entrainer).
-
Reaction progress tracked by acid value (target: <10 mg KOH/g).
4. Dilution & Adjustment
-
Once desired viscosity/acid value reached, resin is cooled to 150-170°C.
-
Thinned with solvents (mineral spirits, xylene) to 50-70% solids.
-
Additives (driers, antioxidants) are blended in.
5. Filtration & Packaging
-
Filtered through micron filters to remove gels/impurities.
-
Packed in drums or totes for storage/shipping.
3.Raw Materials Needed for Alkyd Resin Production
| Category | Key Materials | Function |
|---|---|---|
| Polyols | Glycerol, Pentaerythritol | Provides hydroxyl groups for esterification |
| Dibasic Acids | Phthalic anhydride, Isophthalic acid | Forms polyester backbone |
| Fatty Sources | Soybean oil, Linseed oil, Coconut fatty acids | Imparts flexibility/weatherability |
| Catalysts | Lithium hydroxide, Tin compounds | Accelerates alcoholysis/esterification |
| Solvents | Xylene, Mineral spirits | Reduces viscosity for application |
| Additives | Cobalt/Zirconium driers, Antioxidants | Controls drying/stability |
