Abstract
The invention relates to a reinforcing yarn size for glass fibers and a preparation method thereof, and belongs to the technical field of sizes for glass fibers. The size comprises 4.0-5.5% of a filmogen emulsion, 1.7-4% of a lubricating agent, 0.5-1.5% of a water solubleepoxy resin binder, 0.2-1.0% of an inorganic antistatic agent, 0.5-1.5% of an aminosilane coupling agent and the balance softened water. The filmogen emulsion comprises polyethylene glycol-4000 (PEG-4000), borontrifluoride diethyl etherate, epoxy resin E-44, epoxy resin E-20 and water with a ratio of (1-2): (0.005-0.01): (1-1.5): (0.8-1.2): (8-10). Glass fibers drawn through the size can bear repeatedly bending deformation and have a good textile performance, and woven glass fiber cloth can be applied to production of composite materials without heat treatment and is quick in soakage and high in binding force when compounded with matrix resin.
Description
technical field [0001] The invention relates to a sizing agent and a preparation method thereof. More specifically, the invention relates to a textile-reinforced glass fibersizing agent and a preparation method thereof, belonging to the technical field of glass fibersizing agents. Background technique [0002] The sizing agent can not only effectively lubricate the glass fiber surface, but also integrate hundreds or even thousands of glass fiber monofilaments into a bundle, and can also change the surface state of the glass fiber, which not only satisfies the processing performance of the glass fiber precursor in the subsequent process requirements, and it can also promote the combination of glass fiber and reinforced polymer in composite materials. [0003] All countries attach great importance to the research and development of sizing agents, and invest a lot of manpower and financial resources in the research and development of new sizing agents with better performance....
