Embodiment 1

[0153] Embodiment 1: Catalyst 1,3-bis(2,4,6-trimethylphenyl)-2-(4,5-dibutylimidazolidinylidene) (dichlorobenzylidene) containing butyl substituent base) (tricyclohexylphosphine) ruthenium (I-1) synthesis

[0154] The synthesis of butyl substituent catalyst I-1 comprises the following steps:

[0155] 1) Preparation of N,N'-bis(2,4,6-trimethyl)phenylethylenediimine (9)

[0156]

[0157] Add 3.73 mL of glyoxal (8) aqueous solution (40%) and 80 mL of methanol successively into a 500 mL three-neck flask equipped with a dropping funnel, and stir to dissolve the glyoxal. Add 9.12 mL of m-trimethylaniline (7) and 10 mL of methanol to the dropping funnel, and slowly drop them into the flask. The temperature of the reaction solution was controlled at about 22° C., and stirred for 12 hours. During this process, a bright yellow precipitate slowly precipitated from the reaction solution. After the reaction, the reaction liquid was filtered to obtain a yellow solid, which was washed ...

Embodiment 3

[0181] Example 3: 4-butyl-5-hexyl-1,3-bis(2,4,6-trimethylphenyl)-2-(imidazolidinylidene)(benzylidene)(tricyclohexyl Preparation of phosphine) ruthenium(I-3) dichloride

[0182] 1.1) Preparation of N,N'-bis(2,4,6trimethylphenyl)dodecane-5,6-diamine (14)

[0183]

[0184] Under nitrogen protection, add 2.92g N,N'-bis(2,4,6-trimethyl)phenylethylenediimine (9) (Mw: 292.46g / mol; 10.0 mmol), 100mL tetrahydrofuran was stirred to dissolve it. Then, the ampoule was placed in an ethanol cold bath at -78°C, stirred and cooled. After the reaction solution was fully cooled, 4.17 mL (10.0 mmol) of hexyllithium (2.4 M solution in toluene) was slowly added dropwise with a syringe. The reaction solution was cooled to -78°C again, and 6.25 mL (10.0 mmol) of butyllithium (1.6 M hexane solution) solution was slowly added dropwise with a syringe. After the addition was complete, the reaction mixture was slowly raised to room temperature with stirring, and continued to stir for 0.5 h. Then,...

Abstract

The invention discloses a resin composition, a composite material and a preparation method thereof. The invention particularly discloses a resin composition. The resin composition comprises a composition A and 100-500 parts of fiber reinforcements, wherein the composition A comprises 20-95 parts of dicyclopentadiene, 5-80 parts of epoxy resin, 30-70 parts of an epoxy resin curing agent, 0.1-3 parts of a curing accelerator and 0.1-4 parts of a catalyst composition; and the catalyst composition comprises a ruthenium carbene compound as shown in a formula I or a salt thereof, and chlorinated paraffin, wherein the chlorine content of the chlorinated paraffin is 5%-65%. The resin composition can be stored for a long time, the resin material prepared from the resin composition has good mechanical properties such as tensile strength, tensile modulus and elongation at break, and in addition, the preparation process of the resin material is suitable for industrial continuous production.

Description

technical field [0001] The invention relates to a resin composition, a composite material and a preparation method thereof. Background technique [0002] Dicyclopentadiene (DCPD) is a dimer of cyclopentadiene. It mainly comes from the by-product C5 fraction of petroleum cracking and the by-product light benzene fraction of coal coking. It can be regarded as a primary raw material without organic synthesis. have to. Dicyclopentadiene can be polymerized by metal carbene catalysts to form polydicyclopentadiene with a certain crosslinking structure, so as to improve the tensile strength, fracture toughness and chemical resistance of polyolefin resins. However, a single PDCPD material still has shortcomings in terms of tensile, impact, bending and other mechanical properties, and it is difficult to meet the application requirements of some specific engineering fields, and its comprehensive performance is relatively limited. Therefore, DCPD monomer can be compounded with other r...
