Abstract

The invention relates to a G75 electronic yarn impregnating compound and a preparation method thereof. The G75 electronic yarn impregnating compound is prepared from, by weight, 1.5-9.0% of a starch type film forming agent, 0.5-1.2% of an auxiliary film forming agent, 0.5-3.5% of a lubricant, 0.1-1% of an emulsifier, 0.01-0.2% of an antistatic agent, 0.001-0.01% of a foaming agent and 86-95% of water. The starch type film forming agent is etherification high straight chain starch and etherification crosslinking starch. The auxiliary film forming agent is water-based epoxy resin. The G75 electronic yarn impregnating compound has the excellent film forming performance, the starch film formed by coating glass fiber with the G75 electronic yarn impregnating compound can effectively reduce hair of glass fiber, the good antistatic effect is achieved, meanwhile, the strength of the glass fiber can be enhanced, and the glass fiber has the good tensile property.

Description

technical field [0001] The invention relates to the technical field of electronic spinning, in particular to a G75 electronic yarn sizing agent and a preparation method thereof. Background technique [0002] Electronic yarn is widely used in glass fiber yarn, among which, G75 electronic yarn occupies the mainstream share in the current market. Electronic yarn is a key material for the production of printed circuit boards. It has extremely high requirements for hairiness in the production processes of wire drawing, twisting, and textile. Usually, it is necessary to use a sizing agent to coat the surface of the glass fiber, and it is required that the sizing agent is applied to the glass fiber. Good uniformity of coating on the surface to reduce hairiness. [0003] Among the existing electronic yarn sizing agents, starch-type electronic yarn sizing agents are non-toxic, non-irritating to the human body, have the advantages of easy thermal cleaning and low decomposition temper...
