[0008] The purpose of patent CN 111072921A is to invent an anti-ultraviolet epoxy resin curing agent. The formula they choose has a certain anti-aging effect, but their invention is not suitable for our specific high-end application scene, that is, carbon fiber prepreg curing. They The formula cannot pass the test of SAE J2527 xenon lamp aging for more than 2000 hours, and the formula of patent CN111072921A is mainly solid, and there is a great risk of precipitation in the application field mentioned in the present invention

Patent CN110157298B discloses a yellowing-resistant and antibacterial epoxy resin sealant. The antioxidant they adopt cannot meet the high-temperature curing requirements of carbon fiber ...

Method used

Can find out by above result: the anti-aging auxiliary agent package product of a kind of epoxy resin of the present invention, can give epoxy resin good anti-aging performance, carry out xenon lamp aging test 2000 hours under SAE J2527 standard, follow Compared with the initial color, the color is still well maintained. It can be seen that adding the anti-aging additive package of the present invention can effectively improve the weather resistance of the epoxy resin, and can well endow the epoxy resin with anti-yellowing perf...

Abstract

The invention belongs to the technical field of special auxiliary agents, and discloses an anti-aging auxiliary agent bag and a preparation method thereof, and application of the anti-aging auxiliary agent bag in carbon fiber prepreg. The anti-aging auxiliary agent bag is in a uniform transparent liquid state, and comprises the following components in percentage by mass: 45-60% of a liquid ultraviolet absorbent, 20-40% of a liquid HALS light stabilizer and 10-15% of an antioxidant. The preparation method comprises the following steps: stirring and mixing a liquid ultraviolet absorbent and a liquid HALS light stabilizer, then adding solid antioxidant powder, heating and stirring until the antioxidant powder is completely dissolved, filtering, and cooling to room temperature to obtain a clear and transparent anti-aging additive package product. The anti-aging auxiliary agent bag product provided by the invention can effectively solve the problems that the epoxy resin is not resistant to light aging and thermo-oxidative aging in a high-temperature curing process, has the advantages of small influence on the ground color of the epoxy resin and the like, and is very suitable for being applied to epoxy resin curing carbon fiber prepreg cloth.
