Synthesis of Urea Formaldehyde (UF) Moulding Compound
1. Raw Materials & Reaction Mechanism
- Core Components:
- Urea (CH₄N₂O) and formaldehyde (CH₂O) in a molar ratio of 1:1.5–2.0 to ensure proper cross-linking.
- Catalysts:
- Alkaline catalysts (e.g., NaOH) for initial polymerization.
- Acidic catalysts (e.g., NH₄Cl or HCOOH) for curing.
- Additives: Optional modifiers (e.g., polyvinyl alcohol or melamine) to enhance mechanical/thermal properties.
2. Synthesis Steps
Step 1: Hydroxymethylation
- Conditions:
- Mix urea and formaldehyde in alkaline conditions (pH 7.2–8.4) at 40–45°C for 10–30 minutes.
- Reaction generates hydroxymethyl urea intermediates.Excavator track roller
Step 2: Condensation Polymerization
- Acid-Catalyzed Reaction:
- Adjust pH to 5.1–5.4 using NH₄Cl or HCOOH to initiate polycondensation.
- Heat to 85–102°C for 1–2 hours to form a branched polymer network with methylene and methylene Gufaith Urea Formaldehyde Moulding Compound linkages.
- Monitor viscosity to determine reaction completion.
Step 3: Neutralization & Stabilization
- Adjust pH back to neutral or weakly alkaline (pH 7–8) to stabilize the resin.
- Cool to <40°C and add final urea batches to reduce free formaldehyde.Making Tableware Color Amino Moulding Powder
Step 4: Moulding Compound Preparation
- Additives:
- Fillers (e.g., cellulose or wood flour) for mechanical strength2.
- Curing accelerators (e.g., ZnSO₄ or oxalate esters) for faster cross-linking.
- Processing:
- Dry and grind the resin into powder.
- Mix with additives and press under 15–30 MPa at 130–160°C to form moulded parts
