Anti-bacterial treatment effect of reactive gel catalyst in automotive interior parts
Introduction
With people’s awareness of health and hygiene, antibacterial treatment of automotive interior parts has become an important research field. Car interior parts such as seats, steering wheels, door handles, etc. are often in contact with the human body and are prone to breed bacteria and microorganisms. In order to improve the hygiene level of the interior environment, reactive gel catalysts, as a new antibacterial material, have been gradually applied to the treatment of automotive interior parts. This article will introduce in detail the characteristics of reactive gel catalysts, antibacterial mechanism, application effects in automotive interior parts, and related product parameters.
Characteristics of Reactive Gel Catalyst
1. Basic concepts
Reactive gel catalyst is a gel material with high reactive activity that can catalyze chemical reactions under specific conditions. Its unique structure makes it have excellent antibacterial properties and can effectively inhibit the growth of bacteria and microorganisms.
2. Main ingredients
The main components of reactive gel catalyst include:
- Gel matrix: Usually composed of polymer materials such as polyvinyl alcohol (PVA), polyacrylic acid (PAA), etc., and have good water absorption and stability.
- Catalytics: such as silver ions, copper ions, etc., have strong antibacterial effects.
- Crosslinking agent: used to enhance the mechanical strength and stability of the gel.
3. Product parameters
| parameter name | parameter value | Instructions |
|---|---|---|
| Gel Matrix | Polyvinyl alcohol (PVA) | High water absorption, good stability |
| Catalyzer | Silver Ion (Ag+) | Strong antibacterial, broad-spectrum sterilization |
| Crosslinker | Glutaraldehyde | Enhance the mechanical strength of the gel |
| Anti-bacterial efficiency | >99.9% | Inhibiting effects on common bacteria |
| Service life | >5 years | Life life under normal use conditions |
| Applicable temperature range | -20°C to 80°C | Temperature range suitable for automotive interior parts |
Anti-bacterial mechanism
1. Catalysis
Reactive gel catalysts generate reactive oxygen species (ROS) with strong oxidation properties through catalytic redox reactions, such as hydroxyl radicals (·OH), superoxide anion (O2-), etc. These reactive oxygen species can destroy bacteria’s cell membranes and DNA, thereby achieving bactericidal effects.
2. Ion Release
The silver ions (Ag+) in the catalyst can bind to the thiol group (-SH) on the bacterial cell membrane, destroying the integrity of the cell membrane, causing cell content to leak and eventually leading to bacterial death.
3. Physical adsorption
The gel matrix has a porous structure that is able to adsorb bacteria and microorganisms, limit their activity space, and thus inhibit their growth and reproduction.
Application in automotive interior parts
1. Seats
Car seats are one of the common parts in the car and are prone to bacterial growth. By adding reactive gel catalyst to the seat material, bacterial growth can be effectively inhibited and the seats can be kept clean and hygienic.
Application Effect
| Bacterial species | Initial colony count (CFU/cm²) | Number of colonies after treatment (CFU/cm²) | Antibacterial rate (%) |
|---|---|---|---|
| Escherichia coli | 1.0×10⁵ | <10 | >99.9 |
| Staba aureus | 1.0×10⁵ | <10 | >99.9 |
| Candida albicans | 1.0×10⁵ | <10 | >99.9 |
2. Steering wheel
The steering wheel is a part that drivers often come into contact with, and it is easy to accumulate sweat and oil, becoming a breeding ground for bacterial growth. By applying reactive gel catalyst to the surface of the steering wheel, bacterial growth can be effectively inhibited and the steering wheel is kept clean.
Application Effect
| Bacterial species | Initial colony count (CFU/cm²) | Number of colonies after treatment (CFU/cm²) | Antibacterial rate (%) |
|---|---|---|---|
| Escherichia coli | 1.0×10⁵ | <10 | >99.9 |
| Staba aureus | 1.0×10⁵ | <10 | >99.9 |
| Candida albicans | 1.0×10⁵ | <10 | >99.9 |
3. Door handle
Door handles are often contacted by passengers when getting on and off the bus, and are prone to accumulate bacteria. By applying reactive gel catalyst to the surface of the door handle, bacterial growth can be effectively inhibited and the door handles can be kept clean.
Application Effect
| Bacterial species | Initial colony count (CFU/cm²) | Number of colonies after treatment (CFU/cm²) | Antibacterial rate (%) |
|---|---|---|---|
| Escherichia coli | 1.0×10⁵ | <10 | >99.9 |
| Staba aureus | 1.0×10⁵ | <10 | >99.9 |
| Candida albicans | 1.0×10⁵ | <10 | >99.9 |
4. Air conditioning air outlet
The air conditioner air outlet is an important part of the air circulation in the car, and it is easy to accumulate dust and bacteria. By applying reactive gel catalyst to the surface of the air conditioner outlet, bacterial growth can be effectively inhibited and the air is kept clean.
Application Effect
| Bacterial species | Initial colony count (CFU/cm²) | Number of colonies after treatment (CFU/cm²) | Antibacterial rate (%) |
|---|---|---|---|
| Escherichia coli | 1.0×10⁵ | <10 | >99.9 |
