Sunroof visor and preparation method thereof

Abstract

The invention provides a sunroof visor and a preparation method thereof, wherein the sunroof visor includes a glass fiber layer, an upper glass fiber reinforced polyurethane layer and a lower glass fiber reinforced polyurethane layer; the upper glass fiber reinforced polyurethane layer and the lower glass fiber reinforced polyurethane layer are respectively arranged on and below the glass fiber layer; a non-woven fabric reinforced polyurethane layer is arranged below the lower glass fiber reinforced polyurethane layer or on the upper glass fiber reinforced polyurethane layer. Compared with the prior art, the sunroof visor has outstanding substantial characteristics and obvious progress: 1, the polyurethane product is produced by using the method of increasing the non-woven fabric layer outside the glass fiber mat layer, the radian of the polyurethane product can be changed, and the radian of the product can meet the requirements; and 2, the cost for anew preparing a mold is saved, the manpower is saved, and at the same time, the quality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile accessories, and in particular relates to a sunroof sun visor and a preparation method thereof. Background technique [0002] Glass fiber reinforced polyurethane products are widely used in the field of automotive interiors. The glass fiber reinforced polyurethane product with glass fiber layer sandwich is a new technology that has begun to appear in recent years. The upper and lower surfaces of the product are glass fiber reinforced polyurethane layers, and the middle is a glass fiber layer. With the advantages of high strength, light weight, and stable shape, it has been used more and more in the fields of automotive interiors such as sunroof sun visors and spare tire covers. [0003] Due to the material, production process and other reasons, the radian of the produced product is not consistent with the radian of the mold; because glass fiber reinforced polyurethane is a thermosetting materi...

AI Technical Summary

Problems solved by technology

[0003] Due to the material, production process and other reasons, the radian of the produced product is not consistent with the radian of the mold; because glass fiber reinforced polyurethane is a thermosetting material, these defective products caused by radian problems cannot be repaired, which is a huge waste

There are many reasons for the difference in curvature, some of which are caused by random reasons, which lead to a wide distribution of the curvature of the product, some are larger than the design value, and some are smaller than the design value, and this difference in curvature is difficult to eliminate; in addition There are also some reasons that the radian of the product is generally smaller or larger than the design value (mold radian) due to some specific reasons. Good product, but remaking the mold is time-consuming and laborious, not a very ideal method
