Embodiment 1

[0027] The preparation method of elastic curing resin system is realized through the following steps:

[0028] (1) Mix 20-30 parts of E-51 epoxy resin, 5-7 parts of imidazole latent curing agent and 2-3 parts of organic urea accelerator in parts by weight, and grind it three times with a three-roll mill after stirring evenly. Obtain a composite curing agent;

[0029] (2) Add 20-30 parts of E-51 epoxy resin, 15-20 parts of E-03 epoxy resin and 15-20 parts of novolac epoxy resin into the reaction kettle by weight, set at 160°C-170°C , stir while heating until a transparent liquid is obtained, that is, composite epoxy resin;

[0030] (3) Mix 25-35 parts of the curing agent obtained in step (1) with 65-75 parts of the composite epoxy resin obtained in step (2), and mix evenly in a reaction kettle at 65-70°C to obtain a liquid epoxy resin system ;

[0031] (4) Keep the epoxy resin liquid system obtained in step (3) at a temperature of 70°C-80°C for 4-5h, and then heat up (95°C-1...

Embodiment 2

[0033] The specific steps are the same as in Example 1, except that in step (1), 23-27 parts of E-51 epoxy resin, 6 parts of imidazole latent curing agent and 2-3 parts of organic urea accelerator are mixed in parts by weight.

Embodiment 3

[0035] The specific steps are the same as in Example 1, except that in step (1), 25 parts of E-51 epoxy resin, 6 parts of imidazole latent curing agent and 2.5 parts of organic urea accelerator are mixed in parts by weight.

Abstract

The invention relates to the field of epoxy resin production, and particularly discloses an elastic epoxy resin curing system and a preparing method thereof. The elastic epoxy resin curing system is characterized by being prepared from, by weight, 50-60 parts of E-51 epoxy resin, 15-20 parts of E-03 epoxy resin, 15-20 parts of novolac epoxy resin, 5-7 parts of imidazole latent curing agent and 2-3 parts of organic urea accelerant. The elastic epoxy resin curing system is simple in fat method, easy to operate, high in scientificity and suitable for industrial production, the curing aim of the epoxy resin system at the different temperatures can be achieved, the good technology processing performance which is moderate in viscosity and long in service life is achieved, and the mechanical performance of the cured epoxy resin is also quite good.

Description

(1) Technical field [0001] The invention relates to the field of epoxy resin production, in particular to an elastic curing epoxy resin system and a preparation method thereof. (2) Background technology [0002] Since the appearance of resin-based carbon fiber composite materials in the 1950s, with its unique properties, it is mainly used in cutting-edge science and technology such as rockets, aerospace, and aviation. With the continuous improvement and improvement of the performance of carbon fiber composite materials, the application fields of composite materials With its excellent performance, it has gradually entered the civilian market, and has already occupied a certain seat. At present, it is widely used in the fields of automobile industry, petroleum industry, sports equipment, civil engineering and construction. [0003] In recent years, carbon fiber composite materials have developed rapidly in sporting goods. The sporting goods made of them have the characteristi...
