4. Material Composition

The RBT-250 is produced from solid vulcanized rubber, a compound formulated for maximum mechanical strength, resilience, and chemical resistance.

4.1. Base Polymer Composition

Component	Function
Natural Rubber (NR)	Provides elasticity, resilience, and flexibility
Styrene-Butadiene Rubber (SBR)	Enhances wear resistance and weather stability
Carbon Black (N330)	Reinforces tensile strength and UV stability
Zinc Oxide & Stearic Acid	Curing activators to enhance vulcanization consistency
Sulphur	Crosslinking agent for structural durability
Antioxidants (TMQ / IPPD)	Prevent oxidative degradation under sunlight
Process Oil	Improves mixing and mould flow
Silica Filler (Optional)	Enhances abrasion and tear strength
Pigment Additive	Provides uniform coloration and surface protection

This material blend results in a dense, non-porous, shock-absorbing solid rubber block suitable for both indoor and outdoor industrial use.

 

5. Manufacturing Process

1. Material Mixing:
   All raw materials are batch-blended using a Banbury internal mixer for homogeneous compound consistency.
2. Sheet Forming:
   The mixed compound is calendered into rubber sheets, pre-cut into mould-sized blanks.
3. Compression Moulding:
   Each blank is moulded under high pressure (120–150 bar) and temperature (160–170°C) in precision steel moulds for approximately 12–15 minutes.
4. Curing (Vulcanization):
   The rubber undergoes crosslinking reaction to achieve its permanent elasticity and hardness.
5. Demoulding & Finishing:
   Each part is demoulded, edge-trimmed, and surface cleaned. Optional reflective tape or paint marking can be applied.
6. Quality Inspection:
   100% visual inspection for surface defects, followed by random destructive testing for tensile strength and hardness verification.

 

6. Mechanical & Functional Design

6.1. Structural Geometry

• Wedge Shape: 15° incline angle designed to optimize frictional holding force.
• Base Profile: Cleated, anti-slip design (4 mm depth ridges) for enhanced ground adhesion.
• Tire Contact Surface: Concave curvature (radius ~350 mm) for maximum tire fit and pressure distribution.
• Side Walls: Reinforced with ribbed design to prevent lateral deformation.
• Handle Integration: Dual pre-moulded rope holes (Ø20 mm) for attachment of handle, chain, or rope.

6.2. Anti-Slip Base Analysis

Friction coefficient (μ) on different surfaces (dry and wet):

Surface Type	Condition	Coefficient of Friction (μ)
Concrete	Dry	0.95
Concrete	Wet	0.82
Asphalt	Dry	0.90
Asphalt	Wet	0.78
Steel Plate	Dry	0.85
Steel Plate	Oily	0.68

This ensures stable immobilization performance even under low-traction industrial environments.

 

7. Performance Evaluation
