Laminated paper honeycomb composite material and preparation method thereof

Abstract

The invention provides a laminated paper honeycomb composite material. The section structure thereof includes a surface layer, a transition layer, an intermediate layer and a transition layer from top to bottom, wherein the paper honeycomb material is adopted to be the intermediate layer, and the plastic sheets are adopted to be the transition layers. The invention also provides the method for preparing the laminated paper honeycomb composite material, which can satisfy the conditions such as once-forming of products, no gluewater in procedures and so on. The laminated paper honeycomb composite material has the characteristics of honeycomb structure, no gluewater in procedures and so on; and the material also has the advantages of light weight, high strength, high-temperature resistance, water resistance, corrosion resistance, environmental protection, bacteria prevention, mildew prevention and so on. The characteristics of the material, such as energy absorption, thermoplastic reforming, damping and shock absorption during collision and so on, meet the requirements of development in the prior motor industry.

Description

technical field [0001] The invention relates to a laminated composite paper honeycomb composite material, and also relates to a preparation method of the laminated composite paper honeycomb composite material. Background technique [0002] With the rapid development of the automobile industry in recent years and the continuous change and maturity of the concept of automobile consumers, automobile manufacturers and consumers have higher and higher requirements on the environmental protection and economy of automobiles. According to the results of the "China's First Investigation of Environmental Pollution in Automobiles" released by the Automobile Environment Professional Committee of the Federation of Engineering Societies of the Chinese Association for Science and Technology, 93.82% of the indoor environments of automobiles have varying degrees of pollution. Buying a car, using a car, and maintaining a car have always been the most concerned issues for car owners, and a rec...

AI Technical Summary

Problems solved by technology

According to the assembly and use requirements of automobile interiors, aluminum honeycomb materials have good strength but are not easy to form. They cannot be used in the production of automobile interior parts except for automobile engines and automobile chassis.

For plastic honeycomb materials, because they are all plastic materials, they cannot meet the requirements of high and low temperature resistance and environmental changes during the use of automobiles. At the same time, due to the plastic structure, the honeycomb height is limited, which cannot meet the requirements for high-thickness composite automobile interiors. , because of its pure plastic structure, it is relatively unfavorable for cost control

As for the paper honeycomb material, its structure is reasonable and economical, but its water resistance is poor, easy to deform, and low rigidity, which cannot meet the use and molding requirements of automotive interiors.
