Problems solved by technology

[0002] Nylon 6 is a widely used engineering plastic with excellent comprehensive properties, but it also has disadvantages such as small elastic modulus, easy deformation, poor heat resistance, light resistance, abrasion resistance and moisture absorption.
It is a good solution to modify nylon 6 with inorganic materials, especially inorganic nano-materials. Due to the large specific surface area of ​​nano-inorganic particles, it is easy to agglomerate, and the viscosit

Example Embodiment

[0018] Example 1

[0019] The organic montmorillonite modified by 18 carboxyammonium bromide was modified by aminopropyl POSS. The reaction principle is as follows figure 1 shown. First, 300 mg of organic montmorillonite, magneton and about 150 ml of thionyl chloride were respectively added to a 250 ml single-necked flask, and the reaction was stirred and refluxed for 20 hours at 60°C. It can be seen that before the reaction, it was a light yellow-brown cloudy liquid, and after 24 hours, it was a black cloudy liquid. The activated organic montmorillonite was obtained by suction filtration with a Buchner funnel. Then, the activated organic montmorillonite obtained by suction filtration was added to a 250ml single-necked flask, and then 300mg of aminopropyl POSS, magnetron and about 150ml of tetrahydrofuran were added, and the reaction was stirred and refluxed for 20 hours at 60°C. The gray powdery solid was obtained by suction filtration, placed in a vacuum drying box, dried...

[0020] Example 2

[0021] The organic montmorillonite modified by 18 carboxyammonium bromide was modified by aminopropyl POSS. The reaction principle is as follows figure 1 shown. First, 1.5 g of organic montmorillonite, magnetron and about 150 ml of thionyl chloride were respectively added to a 250 ml single-necked flask, and the reaction was stirred and refluxed for 30 hours at 90°C. It can be seen that before the reaction, it was a light yellow-brown cloudy liquid, and after 24 hours, it was a black cloudy liquid. The activated organic montmorillonite was obtained by suction filtration with a Buchner funnel. Then, the activated organic montmorillonite obtained by suction filtration was added into a 250ml single-necked flask, and then 3g of aminopropyl POSS, magnetron and about 150ml of tetrahydrofuran were added, and the reaction was stirred and refluxed for 30 hours at 90°C. The gray powdery solid was obtained by suction filtration, put into a vacuum drying box, dried i...

[0022] Example 3

[0023] The organic montmorillonite modified by 18 carboxyammonium bromide was modified by aminopropyl POSS. The reaction principle is as follows figure 1 shown. First, 12 g of organic montmorillonite, magneton and about 600 ml of thionyl chloride were respectively added to a 1-liter single-necked flask, and the reaction was stirred and refluxed for 24 hours at 75°C. It can be seen that before the reaction, it was a light yellow-brown cloudy liquid, and after 24 hours, it was a black cloudy liquid. The activated organic montmorillonite was obtained by suction filtration with a Buchner funnel. Then, the activated organic montmorillonite obtained by suction filtration was added to a 1-liter single-necked flask, and then 24 g of aminopropyl POSS, magnetron and about 600 ml of tetrahydrofuran were added, and the reaction was stirred and refluxed for 24 hours at 75°C. The gray powdery solid was obtained by suction filtration, placed in a vacuum drying box, drie...

Abstract

The invention discloses a preparation method of a modified organic montmorillonite/nylon 6 composite material. It utilizes carboxyl group-containing organic montmorillonite to react with amino group-containing cage silsesquioxane to improve the interaction between modified organic montmorillonite and nylon 6, thereby compounding with nylon 6 to prepare a high-performance composite material. The preparation process is to first react carboxyl-containing organically modified montmorillonite with thionyl chloride to activate the carboxyl group, and then react it with aminopropyl cage silsesquioxane (POSS) to generate POSS-modified organic montmorillonite Soil, and then melt-extrude it with nylon 6 to prepare montmorillonite/nylon 6 composites. The composite material obtained in the preparation method of the invention has excellent properties, easy-to-obtain raw materials, simple modification method, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a preparation method of a modified organic montmorillonite / nylon 6 composite material. Background technique [0002] Nylon 6 is a widely used engineering plastic with excellent comprehensive properties, but it also has disadvantages such as small elastic modulus, easy deformation, poor heat resistance, light resistance, abrasion resistance and moisture absorption. It is a good solution to modify nylon 6 with inorganic materials, especially inorganic nano-materials. Due to the large specific surface area of ​​nano-inorganic particles, it is easy to agglomerate, and the viscosity of nylon 6 is large, so the preparation of inorganic particles is small and Uniformly dispersed nylon 6 / inorganic nanocomposites still need to be further improved. At present, the preparation of nylon 6 / montmorillonite composite materials by intercalation polymerization ...
