AI Technical Summary

Problems solved by technology

[0003] 1. The light weight of the paper honeycomb panel is achieved by reducing the weight of the glass fiber layer or PP fiber layer, but it will lead to a significant decrease in the load-bearing performance and impact strength of the product
[0004] 2. After baking, the bonding area between the honeycomb core layer and the skin layer is small. When an external force (≥150N) is applied, the skin layer and the honeycomb core layer will be partially delaminated, which seriously affects the stiffness of the paper honeycomb panel.
[0005] 3. The odor performance of paper honeycomb panels can no longer meet the odor requirements of the current automotive interior, and the largest source of odor is the paper honeycomb core layer

Abstract

The invention provides a spare tire cover plate with light weight, high strength and low odor and a preparation method thereof. The structure of the spare tire cover from top to bottom is fabric, odor absorption layer, PU glass fiber three-dimensional mesh cloth core layer, odor absorption layer, fabric, glass fiber three-dimensional mesh cloth instead of paper honeycomb core, PU foaming liquid The three-dimensional grid is filled to enhance its mechanical properties, and it is prepared by compounding the odor absorption layer and fabric thermal molding.

Description

technical field [0001] The invention belongs to the field of glass fiber reinforced thermoplastic resin composite materials, and in particular relates to a light-weight, high-strength, low-odor spare tire cover plate and a preparation method thereof. Background technique [0002] The car spare tire cover is used to cover and isolate the spare tire compartment, to achieve a flat and partially consistent decoration of the car trunk, and to carry parts for sound insulation. Requirements, the car spare tire cover plays the role of decoration, carrying heavy objects, sound insulation and noise reduction. At present, the most commonly used tire cover material is paper honeycomb spare tire cover. Compared with traditional wood powder board, GMT board, wood board and other materials, it has the characteristics of high strength, light weight and easy molding, but there are still the following problems: [0003] 1. The light weight of paper honeycomb panels is achieved by reducing th...
