Abstract

The invention discloses a modified porous material suitable for a polypropylene material and use thereof, the modified porous material is prepared by using a porous mineral as a matrix and a nucleophilic reagent capable of reacting with a carbonyl group as a modifier; a preparation method of the modified porous material comprises the following steps: 1) dissolving the nucleophilic reagent in waterfor preparing a nucleophilic reagent solution, an emulsion or a suspension to obtain a product A; 2) placing the porous mineral into the product A, stirring for 1-10h, filtering the porous mineral out and drying at 90-130DEG C to obtain a product B; 3) grinding and sieving the product B to obtain a modified porous material. The modified porous material can solve the emission of aldehyde and ketone molecules in the polypropylene material processing process, and has a good adsorption effect on small aldehyde and ketone molecules.

Description

technical field [0001] The invention relates to a modified porous material and its application, in particular to a modified porous material suitable for polypropylene material and its application. Background technique [0002] Modified polypropylene material has been widely used in automotive interior parts, and has the characteristics of low cost, light weight and good performance. The polypropylene material itself is non-toxic. During the use of the car, especially in the high-temperature interior environment, the low-level aldehydes and ketones remaining in the modified polypropylene material will emit and cause damage to the human body. The types of aldehydes and ketones include formaldehyde, acetaldehyde, acrolein, acetone, and volatile aromatic aldehydes, etc., which are mainly derived from residual monomers during the synthesis of polypropylene resins, and small molecules produced during the degradation of modified polypropylene materials. Wait. Therefore, in order ...
