The invention relates to an after-finishing sizing agent for a glass fiber composite mat and a manufacturing method thereof. The sizing agent is characterized by comprising the following raw materials: part A: 3 parts of ethanol, 3 parts of emulsifying agent, 2.5 parts of vinyl trichloro silane A-151 and 0.75 part of glycerin; and part B: 12 parts of polytetrafluoroethylene, 20 parts of non-wovenfabric glue emulsion, 30 parts of ethylene glue, 5 parts of silicone oil 285 and 120 to 160 parts of water, wherein the weight ratio of the part A to the part B is 1-5:1. The dosage of the polytetrafluoroethylene in the formulation of the sizing agent is reduced, and the non-woven fabric glue emulsion in a certain proportion is added. The glass fiber acupuncture composite mat soaked by adopting the sizing agent has the advantages of smooth surface, starched hand feeling, high mat layer stripping force and high solid content of glue, but does not increase the cost, and is accepted by markets.
