Embodiment 1

[0026] Preparation of co-intercalation organic layered silicate: First, 100 parts of sodium-based montmorillonite are stirred in 1000 parts of water at high speed for 2 hours, and then 30 parts of cetyltrimethylammonium bromide are added Continue to stir in the suspension for 2 hours. After the ion exchange reaction is completed, let stand for 24 hours to fully precipitate the suspension, and remove the supernatant to obtain a sludge mixture. Then 40 parts of bisphenol A epoxy resin ARALDITE GY240 (manufactured by CIBA-GEIGY, molecular weight 340-380 , Epoxy value 0.52-0.56) was added to the sludge mixture and fully stirred for 2 hours. Finally, it is dehydrated and dried and the product is crushed to a particle size of 200-400 mesh to obtain co-intercalation organic montmorillonite

[0027] Raw material components: component (A) is 100 parts of homopolymer polypropylene, produced by Daqing Petrochemical Company, the brand is T30S; component (B) is 0.05 parts of dicumyl peroxide...

Abstract

The present invention relates to a high toughness and high rigidity polypropylene nano-composite material prepared by a reactive extrusion and blending method. According to the present invention, with a coupling effect of polypropylene and elastomer macromolecular radical in a reaction by a multi-functional monomer, a interface interaction between the polypropylene and the elastomer macromolecular radical is enhanced so as to improve compatibility and toughness; meanwhile, the multi-functional monomer is inserted into the middle of a layered silicate to generate an in situ grafting intercalation reaction, such that the dispersion separation of the multi-functional monomer in the polypropylene is prompted, the layers of the silicate affect the interface reaction, and provide a stabilizing effect and a refining effect for the elastomer dispersion phase. With the present invention, the co-intercalated organic layered silicate is adopted, and provides a significant rigidity increasing effect and a significant toughness increasing effect; the polypropylene nano-composite material of the present invention has high toughness and rigidity.

Description

Technical field [0001] The invention relates to a polypropylene nano composite material with high toughness and high rigidity and a preparation method thereof. Background technique [0002] Polypropylene is the fastest-growing type of general-purpose plastics. At present, my country’s annual consumption is close to 10 million tons. It has the advantages of light weight, low price, good mechanical properties, good thermal stability, and solvent resistance. Used in industrial fields such as automobiles, home appliances, and packaging, in many cases polypropylene blends and composite materials are used to replace more expensive engineering plastics. But compared with engineering plastics such as nylon and polyester, polypropylene has insufficient rigidity. The flexural modulus of homopolypropylene of high degree (>95%) is about 1400 MPa, while the flexural modulus of nylon 6 and nylon 66 are above 2500 MPa. At the same time, homopolypropylene shows considerable brittleness when ...
