Embodiment 1

[0010] The production method of sizing agent for low-cost electronic grade glass fiber yarn described in this example: first step, first mix 1.8 parts of unmodified high-amylose corn starch and 1.8 parts of modified potato starch with softened water to form starch slurry, stir evenly, Pass the starch slurry through the cooker to control the degree of gelatinization of the starch slurry at 80%; in the second step, dissolve 0.1 parts of plasticizer and 0.2 parts of cationic softener; in the third step, move the gelatinized starch slurry to the mixing In the tank, then add the dissolved plasticizer, fully stir and mix with the starch slurry, then add the dissolved cationic softener, and finally add 1.3 parts of vegetable oil emulsion, add 60 ℃ demineralized water, and control the mixed liquid-solid content at 6.6% , the viscosity is 3mpas.

Embodiment 2

[0012] The production method of sizing agent for low-cost electronic grade glass fiber yarn described in this example: first step, first mix 2.4 parts of unmodified high-amylose corn starch and 2.4 parts of modified potato starch with softened water to form starch slurry, and stir evenly , the starch slurry is passed through the cooker, and the degree of gelatinization of the starch slurry is controlled at 84%; the second step is to dissolve 0.3 parts of plasticizer and 0.4 parts of cationic softener respectively; the third step is to move the gelatinized starch slurry to In the mixing tank, then add the dissolved plasticizer, fully stir and mix with the starch slurry, then add the dissolved cationic softener, and finally add 1.7 parts of vegetable oil emulsion, add 60 ℃ demineralized water, and control the solid content of the mixed liquid at 6.2 %, the viscosity is 7mpas.

Embodiment 3

[0014] The production method of sizing agent for low-cost electronic grade glass fiber yarn described in this example: first step, first mix 2.1 parts of unmodified high-amylose corn starch and 2.1 parts of modified potato starch with softened water to form starch slurry, and stir evenly , the starch slurry is passed through the cooker to control the degree of gelatinization of the starch slurry at 82%; the second step is to dissolve 0.2 parts of plasticizer and 0.3 parts of cationic softener respectively; the third step is to move the gelatinized starch slurry to In the mixing tank, then add the dissolved plasticizer, fully stir and mix with the starch slurry, then add the dissolved cationic softener, and finally add 1.5 parts of vegetable oil emulsion, add 60 ℃ demineralized water, and control the solid content of the mixed liquid at 6.4 %, the viscosity is 5mpas.

[0015] The process requirements for the use of the sizing agent: first, the sizing agent is evenly distributed...

Abstract

A production method of an impregnating agent for low-cost electronic-grade glass fiber yarns is designed in the invention. The impregnating agent mainly comprises 93-95 parts of softened water, 1.8-2.4 parts of unmodified high-amylase corn starch, 1.8-2.4 parts of modified potato starch, 1.3-1.7 parts of a vegetable oil elusion, 0.1-0.3 parts of a plasticizing agent and 0.2-0.4 parts of a cationic softening agent, and the production method is completed through a certain preparation method. Electronic-grade glass fiber yarns produced through using the impregnating agent have the advantages of excellent performances, low cop hairiness rate, uniform yarn stiffness, and complete satisfaction of subsequent operation use performances, and the cost of the impregnating agent for 1t of yarns is low, so the production cost of 1t of the yarns is saved.

Description

technical field [0001] The invention relates to the field of electronic-grade glass fiber yarn sizing agent formulation, in particular to a low-cost electronic-grade glass fiber yarn sizing agent production method developed to reduce waste of electronic-grade glass fiber yarn sizing agent and reduce environmental pollution. Background technique [0002] In the existing sizing formulation, conventionally imported high straight chain modified corn starch and hydrogenated corn oil are used. On the one hand, high straight-chain modified corn starch is not easy to cook and gelatinize during the preparation process, resulting in waste of energy in the preparation of sizing agents; on the other hand, the cost of sizing agents using imported starch and hydrogenated corn oil is relatively high. It is not conducive to the cost advantage of enterprises in the highly competitive market. Contents of the invention [0003] The object of the present invention is to provide a low-cost el...
