Abstract

The invention discloses a carbon fiber sizing agent. The carbon fiber sizing agent is prepared from the following raw materials, a water-based bisphenol A epoxy resin, polyether alcohol, unsaturated acid and water, wherein the weight ratio of the water-based bisphenol A epoxy resin to the polyether alcohol to the unsaturated acid is 1: 0.5 to 5: 0.4 to 5. The polyether alcohol is selected from dimethyl trimer dimethanol; and the unsaturated acid is selected from acrylic acid. The invention also discloses three preparation methods of the carbon fiber sizing agent. The invention also discloses application of the carbon fiber sizing agent in preparation of carbon fibers and carbon fiber composite materials, and the prepared carbon fibers and carbon fiber composite materials. The carbon fibertreated by the sizing agent can be soaked by the polyester resin, so that the carbon fiber can obtain manufacturability similar to glass fiber, and the forming time of the carbon fiber composite material can be greatly reduced, the fixed asset investment of carbon fiber composite material forming equipment is reduced, and the low-cost and quick forming of the carbon fiber composite material are realized.

Description

Technical field [0001] The invention relates to a carbon fiber sizing agent and a preparation method thereof, belonging to the field of carbon fiber and carbon fiber composite materials. Background technique [0002] Resin-based composite materials are fiber-reinforced materials based on organic polymers, and fiber-reinforced materials such as glass fiber, carbon fiber, basalt fiber, or aramid are usually used. Resin-based composite materials are widely used in aviation, automotive, and marine industries. The commonly used resins for fiber-reinforced resin-based composites are epoxy resin and unsaturated polyester resin. The commonly used resins are thermosetting resins, thermoplastic resins, and various modified or blended matrixes. The molding process of the fiber-reinforced resin-based composite material is as follows: the resin first infiltrates the fiber, after the fiber is infiltrated, the resin undergoes cross-linking reaction and solidifies, and the composite material is...
