Abstract

The invention provides a preparation method of a stitch-bonded continuous felt impregnating agent and belongs to the field of preparation of impregnating agents of glass fiber stitch-bonded felts. Thepreparation method of the stitch-bonded continuous felt impregnating agent comprises the following steps of 1, weighing a water soluble film-forming agent, a lubricating agent, a silane coupling agent and a pH value regulator; 2, adding the pH value regulator and deionized water to a reactor and uniformly stirring the pH value regulator and the deionized water; 3, adding the silane coupling agentto the reactor and uniformly stirring an obtained mixture; 4, adding the water soluble film-forming agent to the reactor and uniformly stirring an obtained mixture; 5, adding the lubricating agent tothe reactor and uniformly stirring an obtained mixture; and 6, supplementing deionized water to the reactor and uniformly stirring an obtained mixture to obtain the impregnating agent. The preparation method of the stitch-bonded continuous felt impregnating agent has the advantages that preparation method of the stitch-bonded continuous felt impregnating agent belongs to a water soluble system and is simple to operate and convenient for industrial production; and meanwhile, as water soluble polyester selected in the water soluble film-forming agent contains better ester bonds and ether bonds,the water soluble film-forming agent possesses better hydrophilcity and polarity; and due to the adding of a reactive plasticizer, the product is smooth in a non-dried state and possesses extremely good bundling property in a dried state.

Description

technical field [0001] The invention belongs to the field of wetting agent preparation for glass fiber stitch-bonding mat, in particular to a preparation method of wetting agent for stitch-bonding continuous mat. Background technique [0002] Fiberglass stitched mat is made of roving or square cloth arranged in a certain direction as the base material, after being chopped into a certain length, spread evenly without orientation, and stitched with organic fibers. Fiberglass stitched mats are used to reinforce unsaturated polyester resins and are suitable for FRP molding processes such as pultrusion, injection molding (RTM), winding molding, and hand lay-up. Such as pultruded profile pipes, storage tanks, wind turbine blades and other products. However, the current prior art cannot meet the requirements of the continuous wire throwing operation of the product. It cannot be attached to the wire throwing accessory or is easy to form skin, which makes the wire throwing operatio...
