Abstract

The invention provides a low-VOC (Volatile Organic Compound) glass fiber enhanced polypropylene composite material plate for an automobile and a preparation method thereof. The low-VOC glass fiber enhanced polypropylene composite material plate structurally comprises a honeycomb paper core, wherein glass fiber felts are arranged on the upper and lower surfaces of the honeycomb paper core; hot meltadhesive layers are arranged on the surfaces of the glass fiber felts; polypropylene mixed coatings are arranged on the surfaces of the hot melt adhesive layers; the surfaces of the polypropylene mixed coatings are coated with self-cleaning layers and the self-cleaning layers are nano iron-based titanium dioxide composite photocatalyst coatings; the preparation method of the low-VOC glass fiber enhanced polypropylene composite material plate comprises the following steps: preparing polypropylene mixed coating material liquid; compounding the honeycomb paper core and the glass fiber felts, coating the hot melt adhesive layers, coating the polypropylene mixed coatings and coating the self-cleaning layers. The low-VOC glass fiber enhanced polypropylene composite material plate for the automobile, provided by the invention, has a self-cleaning effect and can be used for adsorbing, decomposing and degrading toxic and harmful gas; a molding technology is simple, and energy saving and environment protection are realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle materials, and in particular relates to a low-VOC glass fiber reinforced polypropylene composite material board for vehicles and a preparation method thereof. Background technique [0002] With the development of the automobile industry, people's lives have become inseparable from the car, and the time spent in the car is getting longer and longer. The impact of the air quality in the car on people's health cannot be underestimated. , has become the focus of social attention. The study found that the air pollution in the car is even more serious than the air pollution outside the car. The main source of air pollution in the car is the interior decoration parts, including: free formaldehyde volatilized from textiles, leather products, plastic products in the car, etc. Various volatile organic compounds (VOCs) such as alkanes, benzene, toluene, xylene and aldehydes. VOCs can cause the central nerv...
