Abstract

The invention discloses a sulfonated polyaryletherketone water-based sizing agent as well as a preparation method and application thereof. The sizing agent is prepared from the following raw materials in parts by mass: 0.1-40 parts of main size, 0-15 parts of an emulsifier and 100 parts of deionized water, wherein the main size is sulfonated polyaryletherketone resin. The preparation method comprises the following steps: firstly, adding the emulsifier to the deionized water, and conducting heating and uniformly stirring; adding the sulfonated polyaryletherketone resin, and conducting stirring until no obvious solid residue exists; and conducting cooling to room temperature while stirring to obtain the sulfonated polyaryletherketone water-based sizing agent. When the sizing agent is used, the deionized water is added and uniformly stirred according to the specific requirements of different fiber sizing processes on the concentration of the sizing agent, and a universal dipping sizing process is adopted for sizing. According to the sulfonated polyaryletherketone water-based sizing agent, sulfonated polyaryletherketone with the structure similar to that of matrix resin polyether-ether-ketone serves as the main size, the wettability and roughness of the surfaces of carbon fibers are improved after sizing, and the interface bonding capacity between the carbon fibers and the matrix resin can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fiber sizing agents, in particular to a sulfonated polyaryletherketone water-based sizing agent and its preparation method and application. Background technique [0002] Carbon fiber is a high-performance fiber with a carbon content of more than 90%. It has a series of excellent physical and chemical properties such as low density, high specific strength, high specific modulus, high temperature resistance, corrosion resistance, and fatigue resistance, and has become the most commonly used reinforcement material in fiber reinforced composite materials. In the past more than half a century, carbon fiber composite materials have played an important role in the fields of aerospace, aviation, automotive structural parts, fan blades, and life and leisure products. For continuous fiber-reinforced resin-based composites, the strength of the interfacial bonding between the fiber and the matrix resin plays a key r...
