[0021] Embodiment 1

[0022] like Figure 1 - Figure 3 As shown, a novel wear-resistant non-woven composite glass fiber chopped strand mat, a novel wear-resistant non-woven composite glass fiber chopped strand mat, comprises a non-woven fabric 1 and a glass fiber layer 12, a No. 1 latex layer 22 is laid on the non-woven fabric 1, a reinforcing layer 2 is adhered to the No. 1 latex layer 22, and the reinforcing layer 2 is adhered to the non-woven fabric 1 through the No. 1 latex layer 22, a No. 2 latex layer 221 is laid on the reinforcing layer 2, a strong and tough layer 21 is adhered to the No. 2 latex layer 221, and the glass fiber layer 12 is adhered to the strong and tough layer 21, the glass fiber chopped strand mat is a composite of non-woven material and glass fiber, and is commonly used for insulation and heat preservation inside a car, it can help control the temperature inside the car, prevent heat or cold from the external environment from entering the interior of the vehicle, and improve air conditioning The efficiency of the system is improved and energy consumption is reduced. However, the strength and toughness of the non-woven composite glass fiber chopped strands mat are low, and it is easy to be damaged during use, so that it needs to be frequently replaced and repaired. When the strength of the non-woven composite glass fiber chopped strands mat is increased, the strength of the non-woven composite glass fiber chopped strands mat is increased by providing a reinforcing layer 2. First, the reinforcing layer 2 is added between the non-woven fabric 1 and the glass fiber layer 12. The reinforcing layer 2 of polymer material can effectively increase the strength of the non-woven composite glass fiber chopped strands mat. At the same time, the toughness of the non-woven composite glass fiber chopped strands mat is increased through the grid-like strong and tough layer 21, so that the non-woven composite glass fiber chopped strands mat is not easy to be damaged, and the service life of the non-woven composite glass fiber chopped strands mat is effectively extended.

[0023] Furthermore, the strong and tough layer 21 is in a grid shape, and the strong and tough layer 21 is made of plastic material, and the reinforcing layer 2 is made of polymer material, which has high elasticity and high toughness. First, the strong and tough layer 21 is placed on the second latex layer 221, and the second latex layer 221 will overflow through the grid of the strong and tough layer 21, and then the glass fiber layer 12 is placed on the strong and tough layer 21, and the glass fiber layer 12 is adhered by the overflowed second latex layer 221, and the toughness of the non-woven composite glass fiber chopped strands is further improved by the strong and tough layer 21.

[0024] Embodiment 2

[0025] like Figure 1 and Figure 3As shown, the utility model proposes a new type of wear-resistant non-woven composite glass fiber chopped strands mat. Compared with Example 1, as another implementation mode of the utility model, a heat-resistant layer 3 is bonded to the glass fiber layer 12, and the heat-resistant layer 3 is made of polytetrafluoroethylene. When the heat resistance of the non-woven composite glass fiber chopped strands mat is increased, the heat-resistant effect of the non-woven composite glass fiber chopped strands mat is increased by providing the heat-resistant layer 3. The heat-resistant layer 3 made of polytetrafluoroethylene has excellent heat resistance, which can protect the non-woven composite glass fiber chopped strands mat from withstanding heat in a high temperature environment without melting or deforming, thereby improving the high temperature resistance of the non-woven composite glass fiber chopped strands mat.

[0026] Furthermore, a waterproof coating 31 is bonded to the heat-resistant layer 3, and the waterproof coating 31 is made of polyester-amine material. The waterproof coating 31 made of polyester-amine material has good waterproof performance, which can effectively prevent moisture from penetrating into the non-woven composite glass fiber chopped strands mat and protect the non-woven composite glass fiber chopped strands mat from being eroded by moisture.

The wear-resistant layer 13 made of polyurethane has good wear resistance and can effectively protect the surface of the non-woven composite glass fiber chopped strand mat from friction and wear factors, and effectively protect the surface fibers of the glass fiber layer 12 from wear.

[0028] Working principle: When using this new type of wear-resistant non-woven composite glass fiber chopped strands mat, first, when increasing the strength of the non-woven composite glass fiber chopped strands mat, the strength of the non-woven composite glass fiber chopped strands mat is increased by providing a reinforcing layer 2. First, a reinforcing layer 2 is added between the non-woven fabric 1 and the glass fiber layer 12. The reinforcing layer 2 made of polymer material can effectively increase the strength of the non-woven composite glass fiber chopped strands mat. At the same time, the toughness of the non-woven composite glass fiber chopped strands mat is increased through the grid-shaped strong and tough layer 21, so that the non-woven composite glass fiber chopped strands mat is not easy to be damaged, thereby effectively extending the service life of the non-woven composite glass fiber chopped strands mat.

[0029] Finally, when increasing the heat resistance of the non-woven composite glass fiber chopped strands mat, the heat resistance of the non-woven composite glass fiber chopped strands mat is increased by providing a heat-resistant layer 3. The heat-resistant layer 3 made of polytetrafluoroethylene has excellent heat resistance and can protect the non-woven composite glass fiber chopped strands mat from withstanding heat in a high temperature environment without melting or deforming, thereby improving the high temperature resistance of the non-woven composite glass fiber chopped strands mat.
