Introduction
With the continuous growth of global energy demand and the increase in environmental protection awareness, insulation materials are becoming more and more widely used in construction, industry, transportation and other fields. The main function of thermal insulation materials is to reduce heat transfer, thereby improving energy utilization efficiency and reducing energy consumption. However, traditional insulation materials have certain limitations in thermal insulation properties and cost. In recent years, the research and development and application of the new generation of sponge hardener has brought revolutionary breakthroughs in the manufacturing of insulation materials. This article will discuss in detail the key position of the new generation of sponge hardeners in the manufacturing of insulation materials, analyze how it improves thermal insulation performance and reduces costs, and combines domestic and foreign literature and product parameters to provide rich data support.
1. Basic concepts and classifications of thermal insulation materials
1.1 Definition of insulation material
Insulation materials refer to materials that can effectively reduce heat transfer, which are usually used for insulation and insulation of buildings such as walls, roofs, floors, etc., as well as industrial equipment, pipelines, etc. The main performance indicators of thermal insulation materials include thermal conductivity, density, compressive strength, water absorption, etc.
1.2 Classification of insulation materials
Depending on the material, insulation materials can be divided into the following categories:
- Inorganic insulation materials: such as rock wool, glass wool, aluminum silicate fiber, etc.
- Organic insulation materials: such as polystyrene foam (EPS), extruded polystyrene (XPS), polyurethane foam (PUR), etc.
- Composite insulation materials: such as composite silicate insulation materials, composite polyurethane insulation materials, etc.
2. Limitations of traditional insulation materials
2.1 Insufficient thermal insulation performance
The traditional insulation materials have certain limitations in thermal insulation properties. For example, polystyrene foam (EPS) and extruded polystyrene (XPS) have a high thermal conductivity, resulting in poor thermal insulation. In addition, although inorganic insulation materials such as rock wool and glass wool have good thermal insulation properties, their density is relatively high, increasing the load on the building.
2.2 Higher cost
The production cost of traditional insulation materials is relatively high, especially in high-performance insulation materials. For example, although polyurethane foam (PUR) has excellent thermal insulation properties, its raw materials are expensive, resulting in an increase in overall costs. In addition, the construction cost of traditional insulation materials is also high, requiring a professional construction team and equipment.
3. Research and development background of the new generation of sponge hardener

3.2 Technology Progress
In recent years, technological advances in the chemical industry have provided the possibility for the research and development of a new generation of sponge hardener. Through nanotechnology, polymer synthesis technology and other means, researchers have successfully developed sponge hardener with excellent performance, which can significantly improve the thermal insulation performance and mechanical strength of insulation materials.
