Fully Automatic Silicone Sealant Production Line
-
≥1/set
USD 150,000.00
1. Introduction to Silicone Sealant Adhesives
Silicone sealant adhesives are versatile, elastic polymers used for bonding, sealing, and waterproofing in construction, automotive, and industrial applications. They offer:
-
Excellent flexibility (up to 600% elongation)
-
Weather/UV resistance
-
Thermal stability (-50°C to +200°C)
-
Strong adhesion to glass, metal, ceramics
Common types:
-
Acetoxy-cure (acetic acid smell, general-purpose)
-
Neutral-cure (alcohol/oxime-based, metal-friendly)
-
MS Polymer (modified silicone, low VOC)
2. Raw Materials & Their Functions
| Material | Function | Typical Content (%) |
|---|---|---|
| Base Polymer | ||
| Polydimethylsiloxane (PDMS) | Primary silicone rubber backbone | 40-60% |
| Fillers | ||
| Calcium carbonate | Extender, cost reduction | 20-35% |
| Fumed silica | Reinforcer, thixotropy control | 5-10% |
| Crosslinkers | ||
| Methyltrimethoxysilane | Acetoxy-cure crosslinker | 3-8% |
| Vinyltriethoxysilane | Neutral-cure crosslinker | 2-5% |
| Catalysts | ||
| Dibutyltin dilaurate (DBTL) | Accelerates curing | 0.1-0.5% |
| Additives | ||
| Pigments (TiO₂/Fe₂O₃) | Color | 1-3% |
| Adhesion promoters | Enhances bonding (e.g., aminosilanes) | 0.5-2% |
3. Step-by-Step Production Process
Stage 1: Pre-Mixing & Dehydration
-
Weighing
-
PDMS polymer + fillers (CaCO₃/silica) measured precisely.
-
-
Vacuum Mixing
-
Loaded into a planetary mixer with vacuum (heated to 120°C).
-
Mix at 20-50 rpm for 30-60 mins under -0.095 MPa vacuum to remove moisture.
-
Stage 2: Crosslinker & Catalyst Addition
-
Cooling
-
Temperature reduced to 50°C to prevent premature curing.
-
-
Liquid Additives
-
Crosslinker (e.g., methyltrimethoxysilane), catalyst (DBTL), and pigments added.
-
-
Homogenization
-
Mixed for 15-30 mins until viscosity reaches 50,000-150,000 cP.
-
Stage 3: Quality Control & Filling
-
Testing
-
Check viscosity (Brookfield RV), extrusion rate (ASTM C1183), and skin time.
-
-
Degassing
-
Final vacuum treatment to remove air bubbles.
-
-
Packaging
-
Filled into cartridges/sausage packs via servo-driven piston filler.
