Embodiment 1

[0045] After 3g of silicon-based mesoporous molecular sieve was dried for 2h in a vacuum environment at 200℃ and pressure <0.1MPa, 97g of styrene with 300mg of dibenzoyl peroxide dissolved in it was added to it, and dispersed and infiltrated by ultrasonic waves with a frequency of 59KHz for 30min , Immerse for 60h under vacuum conditions at room temperature and pressure <0.1MPa to obtain a mixture of styrene and molecular sieve. After pre-polymerization for 1.5 hours at 88°C under nitrogen protection with a flow rate of 3ml / min and stirring at a speed of 100rpm, it was cast in a petri dish; then it was further polymerized at 65°C for 18h and treated at 100°C for 2h to make the reaction complete and remove impurities. After the reaction monomers and oligomers are cooled, a polystyrene / mesoporous molecular sieve composite material containing about 3% of the mesoporous molecular sieve is obtained.

[0049] After 7g of silicon-based mesoporous molecular sieve was dried for 2h in a vacuum environment at 200℃ and pressure <0.1MPa, 300mg of dibenzoyl peroxide dissolved in 93g of styrene was added to it, and dispersed and infiltrated by ultrasonic waves with a frequency of 59KHz for 30min , Immerse for 60h under vacuum conditions at room temperature and pressure <0.1MPa to obtain a mixture of styrene and molecular sieve. After pre-polymerization for 1.5 hours at 88°C under nitrogen protection with a flow rate of 3ml / min and stirring at a speed of 100rpm, it was cast in a petri dish; then it was further polymerized at 65°C for 18h and treated at 100°C for 2h to make the reaction complete and remove impurities. After the reaction monomers and oligomers are cooled, a polystyrene / mesoporous molecular sieve composite material containing about 7% of the mesoporous molecular sieve is obtained.

Abstract

The invention discloses a composite material and interface structure and preparing method, which comprises the following steps: choosing medium hole polymer molecule organic monomer and reaction aids as raw material; adding the medium hole molecular screen into liquid organic monomer dissolved with reaction aids; generating organic polymer molecule in the pore path of the medium hole molecular screen; projecting along pore path to outside under proper polymeric condition; forming organic-inorganic interconnected network hybridization particle; merging the organic polymer molecule in molecular screen and homopolymer molecule out of the molecular screen tightly; forming the product. The interface structure of this composite material likes 'rambutan' appearance, which hot property and dynamic property possesses bigger improvement.

Description

Technical field [0001] The invention relates to an organic polymer modified composite material and a preparation method thereof, in particular to a composite material formed by an organic polymer and a mesoporous molecular sieve (hereinafter referred to as "polymer / mesoporous molecular sieve composite") and its interface structure And preparation method. Background technique [0002] Organic polymers are widely used in molded products, packaging materials, films, building materials and other fields in electronic appliances, automobiles, and household daily necessities. However, shortcomings such as poor heat resistance and mechanical properties affect its application to a certain extent. [0003] At present, there are many studies on polymer-based nanocomposites that use inorganic substances to enhance and modify polymers. However, due to the significant self-aggregation between ordinary inorganic nanoparticles, it is difficult for the existing blending technology to achieve the ...
