Low Odor Catalyst LE-15: Injecting green soul into building insulation materials
In the field of construction, insulation materials are like a thick coat in winter, providing buildings with dual protection of warmth and energy saving. However, chemical catalysts used in traditional insulation materials are often accompanied by pungent odors and potential environmental hazards, which is like dyeing a delicate coat with a lingering odor. The emergence of the low-odor catalyst LE-15 is like a fresh spring breeze, which completely changed this situation.
LE-15 is an environmentally friendly catalyst designed for polyurethane foaming systems. It not only effectively promotes the reaction between isocyanate and water, but also significantly reduces the emission of volatile organic compounds (VOCs). This means that using LE-15’s insulation material not only maintains excellent physical properties, but also keeps construction workers and residents away from the trouble of pungent odors. From the laboratory to the construction site, LE-15 is quietly launching a “green revolution”, injecting a more environmentally friendly soul into building insulation materials.
This article will discuss in-depth the application of LE-15 in improving the environmental protection performance of building insulation materials. We will analyze it from multiple angles such as its product parameters, mechanism of action, practical application cases, and domestic and foreign research progress, and strive to fully demonstrate how this innovative catalyst plays an important role in the construction industry. At the same time, we will lead readers into the world of LE-15 with easy-to-understand language and vivid and interesting metaphors, and uncover the scientific and technological mysteries behind it.
LE-15’s product parameters: the power behind data
To gain a deeper understanding of the charm of LE-15, you must first be familiar with its various parameters. These seemingly cold data actually contain powerful functions and advantages. The following are the main technical indicators of LE-15:
| parameter name | Data Value | Unit | Remarks |
|---|---|---|---|
| Appearance | Light yellow transparent liquid | — | Easy to identify, easy to operate |
| Density | 1.02 | g/cm3 | Lightweight design for easy transportation |
| Viscosity | 30 | mPa·s | Moderate viscosity, easy to mix |
| pH value | 7.0 | — | Neutral, no corrosion risk to the equipment |
| Active ingredient content | ≥98% | % | High purity, significant catalytic effect |
| VOC content | ≤50 | mg/kg | Complied with strict environmental protection standards |
Parameter Interpretation
-
Appearance and density
The appearance of the LE-15’s pale yellow transparent liquid makes it easy to identify during production and avoid confusion with other chemicals. Its density is only 1.02 g/cm3, which is lighter than other similar catalysts, which is particularly important for large-scale transportation and storage. -
Viscosity and pH
Viscosity is a key indicator for measuring liquid fluidity. The viscosity of LE-15 is 30 mPa·s, which not only ensures its uniformity during the mixing process, but does not increase the difficulty of stirring due to excessive viscosity. In addition, the neutral pH value makes it almost free of corrosion to the production equipment and extends the service life of the equipment. -
Active ingredient content and VOC content
The active ingredient content of up to 98% means that LE-15 can achieve the ideal catalytic effect in a smaller amount, thereby reducing production costs. At the same time, its VOC content is less than 50 mg/kg, which is far lower than the requirements of international environmental protection standards, ensuring the safety and environmental protection of the product.
Through these parameters, we can clearly see the outstanding performance of LE-15 in terms of environmental protection and performance. Next, we will further explore its specific role in practical applications.
The mechanism of action of LE-15: The magic journey of the catalyst
Catalytics are like “magics” in chemical reactions, which accelerate the occurrence of chemical reactions by changing the reaction path. As an efficient catalyst, the mechanism of action can be described in a vivid metaphor: Imagine that you are trying to travel through a dense forest to reach your destination. Without a guide, you may be disoriented and spend a lot of time and energy; but if you have an experienced guide, he can find a shortcut for you to reach your goal quickly. In chemical reactions, LE-15 is the “guidance”.
Specific action mechanism
LE-15 mainly works in the following two ways:
-
Promote isocyanate and waterReaction
During the polyurethane foaming process, the reaction of isocyanate with water is a key step in the formation of carbon dioxide gas. LE-15 makes this process more rapid and controllable by reducing the reaction activation energy. This acceleration effect not only improves production efficiency, but also ensures the uniformity and stability of the foam structure. -
Reduce the occurrence of side reactions
In traditional catalytic systems, due to the difficulty in controlling the reaction conditions, it is often accompanied by some unnecessary side reactions, such as the production of excessive amines or aldehydes. These by-products will not only affect the performance of the final product, but will also increase the emission of VOC. By optimizing the reaction path, LE-15 effectively reduces the occurrence of these side reactions, thereby improving the environmental performance of the product.
Kinetic Analysis
To understand the mechanism of action of LE-15 more intuitively, we can explain it through a set of experimental data. The following table shows the reaction rate comparison when using LE-15 and other conventional catalysts under the same conditions:
| Catalytic Type | Reaction rate (min?1) | Foam density (kg/m3) | VOC emissions (mg/kg) |
|---|---|---|---|
| Traditional Catalyst A | 0.5 | 38 | 120 |
| Traditional Catalyst B | 0.6 | 40 | 100 |
| LE-15 | 0.8 | 36 | 50 |
It can be seen from the table that LE-15 not only significantly improves the reaction rate, but also reduces foam density and VOC emissions, which is an important reason why it stands out in terms of environmental protection performance.
Practical application case: LE-15’s stage practice
No matter how perfect the theory is, it needs to be verified in practice. LE-15 has been widely used in several building insulation projects and has achieved remarkable results. The following are several typical case analysis.
Case 1: Exterior wall insulation project of a large commercial complex
Project background
This commercial complex is located in a city in the south. It has a high annual temperature and requires extreme thermal insulation performance of exterior wall insulation materials.For strict. At the same time, due to its location in a bustling area, the odor problems generated during construction have also attracted much attention.
Solution
In this project, the construction party used polyurethane hard bubbles with LE-15 as catalyst as the exterior wall insulation material. The results show that LE-15 not only effectively improves the insulation performance of the foam, but also controls the VOC emissions during construction to an extremely low level, winning unanimous praise from surrounding residents.
Data comparison
| Indicators | Traditional catalyst solution | LE-15 Solution |

Case 2: Roof insulation renovation of residential buildings in cold northern areas
Project background
This project is located in a cold area in the north, and the temperature can drop below minus 30℃ in winter. The original roof insulation materials can no longer meet the current energy-saving needs and need to be upgraded and renovated urgently.
Solution
The polyurethane hard bubble catalyzed by LE-15 is used as the new roof insulation material. After a year of operation monitoring, the new system has shown excellent cold resistance and thermal insulation, while greatly improving indoor air quality.
Data comparison
| Indicators | Before transformation | After the transformation |
|---|---|---|
| The increase in room temperature in winter | 2℃ | 4℃ |
