Problems solved by technology
The existing heat insulation pads mainly have the following problems: 1. The sound absorption index does not meet the requirements; 2. The rigidity of the product is poor, especially for products with light weight; 3. The product is heavy, which is not conducive to the lightweight of the whole vehicle; 4. , OEMs require cost reduction every year, resulting in no profit margin for sound insulation pads made of existing materials
The above two groups of materials have disadvantages. The surface layer of aluminum foil + glass wool is aluminum foil, which is easy to be damaged. After the aluminum foil is damaged, the glass wool will deteriorate or be damaged when it encounters high temperature; non-woven fabric + hot-melt felt. High temperature resistance, the engine is easy to catch fire when the engine is extremely high temperature; at the same time, the sound insulation and heat insulation effect of the above two groups of materials is not obvious

Embodiment
[0018] The invention provides a commercial vehicle heat insulation pad with high temperature resistance and high flame retardancy
[0019] The heat insulation pad adopts a multi-layer composite structure: the surface layer is non-woven fabric; the inner surface layer is hot-melt felt; the inner layer is glass wool; the bottom layer is aluminum foil.
[0020] The invention provides a method for manufacturing a commercial vehicle heat insulation pad with high temperature resistance and high flame retardancy
[0021] (1) Cutting process: First, according to the size of the product, the non-woven fabric, hot-melt felt, glass wool and aluminum foil are pre-cut by cutting tools;
[0022] (2) Composite process: Then, according to the placement of the concave and convex molds of the mold, place the cut non-woven fabric, hot-melt felt, glass wool and aluminum foil in the mold in turn, and perform mechanical compression and compounding to obtain the tablet;
[0023] (3) Hot pressing fo...

The invention relates to the technical field of commercial vehicle heat insulation pads, in particular to a high-temperature-resistant and high-flame-retardant commercial vehicle heat insulation pad and a manufacturing method thereof. The heat insulation pad is of a multi-layer composite structure, wherein a surface layer is made of non-woven fabric, the inner surface layer is a hot melting felt,the lining layer is made of glass wool, and the bottom layer is aluminum foil. By means of the multi-layer composite structure, the produced heat insulation pad is not prone to damage, resistant to high temperature and good in sound insulation and heat insulation performance.
Description
technical field [0001] The invention relates to the technical field of commercial vehicle heat insulation pads, in particular to a commercial vehicle heat insulation pad with high temperature resistance and high flame retardancy and a manufacturing method thereof. Background technique [0002] Car heat insulation pads are generally installed in the engine compartment of cars to play the role of heat insulation, sound insulation and beautification. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as high sound absorption, low weight, high strength, and high heat insulation of heat insulation pads have become bottlenecks, restricting the development of he...
