Embodiment

[0047] In the embodiment of the present invention, the content of water accounts for 94% of the total mass of the wetting agent. Table 1 shows the percentage value of the solid mass of each component in the wetting agent to the total mass of the wetting agent. The corresponding value of each component is the mass percentage / %. Among them, the coupling agent uses γ-methacryloxypropyl trimethoxysilane (production grade is A-174), γ-aminopropyltriethoxysilane (production grade is A-1100), γ- One or more of (2,3-glycidoxy)propyltrimethoxysilane (A-187) and vinyltris(β-methoxyethoxy)silane (A-172); Lubricant uses PEG1000; film-forming agent A uses unsaturated polyester resin emulsion (production grade is Neoxil 954); film-forming agent B uses epoxy resin emulsion (production grade is BH-620); pH regulator uses acetic acid.

Abstract

The invention provides a glass fiber sizing agent. The sizing agent comprises a coupling agent, a lubricating agent, a film forming agent A, a film forming agent B, a pH value modifier and water, the coupling agent is one or more of silane coupling agents containing vinyl, methacrylonitrile epoxide, amidogen and epoxy groups, the film forming agent A is polyester resin emulsion, and the film forming agent B is epoxy resin emulsion, wherein the solid mass of the sizing agent accounts for 4%-12% of the total mass of the sizing agent. Different kinds of film forming agents high in content are compounded and matched with the proper coupling agent, lubricating agent and pH value modifier to prepare the sizing agent high in permeation speed and good in compatible effect. Yarn prepared through the sizing agent is soft and high in permeation speed and has excellent pultrusion performance and good resin compatibility. The invention further provides application of the sizing agent in the pultrusion process of alkali-free glass fiber reinforced umbrella frames.

Description

technical field [0001] The invention relates to the field of sizing agents, in particular to a glass fiber sizing agent and its application. Background technique [0002] Since the 1990s, my country has introduced the pultrusion molding process from the United States to produce glass fiber composite profiles. After the lining is fully impregnated, a series of preformed templates are combined and guided to obtain a preliminary shape, and finally enter the heated metal mold, and react and solidify under a certain temperature, so as to obtain a continuous, smooth surface, stable size, and high strength. composite profiles. [0003] The glass fiber used in the pultrusion process will be coated with a sizing agent. The use and selection of the sizing agent is not only critical to the formability of the glass fiber composite profile, but also affects the compatibility of the subsequent glass fiber with the matrix resin and the mechanical properties of the product. For example, ta...
