Problems solved by technology

However, there are disadvantages such as uneven filler dispersion, poor formaldehyde removal effect, and poor biodegradability.
[0006] To sum up, in the currently commonly used methods for removing formaldehyde from automotive interiors, the adsorption capacity of physical adsorbents is limited and the adsorption efficiency is low, while the dispersion of chemical catalysts is poor, the efficiency of removing formaldehyde is low, and the interior plastics are difficult to decompose, which is poor in environmental protection , which restricts its application in automotive interiors, so it is of great significance to develop a composite plastic for automotive interiors that can remove formaldehyde and be environmentally friendly.

Abstract

The invention belongs to the technical field of automobile interiors, and provides a formaldehyde-degrading degradable automotive interior foamed plastic and a preparation method thereof. The method comprises the following steps: grafting the surface and the apertures of a porous inorganic filler with (tetracarboxyphthalocyaninato)iron (II), adding a prepolymer system of vegetable oil and toluenediisocyanate, and performing foaming and aging to obtain the formaldehyde-degrading degradable automotive interior foamed plastic. Compared with foamed plastics prepared through conventional methods,the automobile interior foamed plastic prepared in the invention has the advantages of uniformity in filler dispersion, realization of the combination of physical adsorption and chemical catalytic oxidation of formaldehyde, high purification efficiency, long service life, biodegradability and good environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and provides a formaldehyde-removing and degradable foam plastic for automobile interior decoration and a preparation method. Background technique [0002] With the continuous improvement of living standards, cars are no longer luxury goods, and are no longer just a few people's patents. More and more people buy private cars, but there will often be unpleasant smells in the car, which is a problem for every car owner. Added a lot of troubles, especially for new cars. The peculiar smell in new cars is often harmful gases such as formaldehyde emitted from the car, which is very harmful to the human body. It is necessary to seek an effective method to remove formaldehyde and eliminate peculiar smell in the car. It has become a confusion for many car owners and an important research topic in the automotive industry. [0003] At present, there are various methods for removing f...
