Problems solved by technology

The performance of starch will vary with different batches. Under normal circumstances, the use of sizing formulated with starch with too low or too high viscosity will result in too weak or too strong adhesion to the tow, while using the tow Cloth woven with loose electronic yarn is prone to monofilament breakage and affects the quality of the cloth surface; on the contrary, cloth woven with tight tow electronic yarn has high air permeability, both of which will seriously affect the performance of electronic textile fabrics and even copper-clad panels. quality

Embodiment 1

[0024] The starch type textile sizing agent of configuration 1940Kg, and each component is weighed respectively by following weight ratio:

[0025]

[0026] The preparation steps are as follows:

[0027] (1) Weigh each of the above substances in proportion.

[0028] (2) Pour the hot-melted triglycerides and fatty acid esters, as well as polyoxypropylene ether, fatty acid polyoxyethylene amide and stearamide acetate into stainless steel barrels in turn, and use a homogenizer to mix each Stir the components evenly to obtain a mixture, then add 65°C deionized water to emulsify, add 65°C deionized water into the bucket after 6 minutes and stir evenly to obtain an emulsion. Wherein the total mass of deionized water is 10 times of the mass of the mixture.

[0029] (3) Pour octadecyl dimethyl ammonium chloride into a stainless steel bucket, and add 10Kg of deionized water at 65°C to the bucket, then stir for more than 5 minutes, and set aside;

[0030] Pour GF-803 (modified wat...

Embodiment 2

[0035] The difference between this embodiment and Example 1 is that the hydroxypropyl etherified corn starch A with a viscosity of 11cps is changed to the hydroxypropyl etherified corn starch A with a viscosity of 8cps; the hydroxypropyl ether with a viscosity of 17cps It is the hydroxypropyl etherified corn starch B of 15cps that the corn starch B is changed into viscosity. Other components, consumption and preparation method are all identical with embodiment 1.

Embodiment 3

[0037] It is the hydroxypropyl etherified corn starch A that the viscosity is 11cps to be changed into the hydroxypropyl etherified corn starch A of 10cps; Etherified corn starch B. Other components, consumption and preparation method are all identical with embodiment 1.

Abstract

The invention relates to the technical field of glass fiber yarns, and in particular relates to a starch-type textile impregnating compound and a preparation method thereof. The starch-type textile impregnating compound mainly consists of modified maize starch A, modified maize starch B, mixed oil, lubricating oil, a non-ionic surface active agent, faliphatic polyoxyethylene amide, a cationic surface active agent, a water-soluble epoxy resin derivative, an anticorrosion agent, a deforming agent and water. The starch-type textile impregnating compound is prepared in the steps of dissolving, heating, thermally preserving and cooling each component and mixing all components. By utilizing the appropriate water-soluble epoxy resin derivative and utilizing the modified maize starch A and the modified maize starch B, the impregnating compound has the appropriate caking property, and the viscosity is maintained in the range of 6.0 to 6.8cps. Even if the high-viscosity starch is adopted as a raw material, the prepared impregnating compound is still low in viscosity, so that the problem that the air permeability of a piece of glass cloth prepared by the impregnating compound prepared by the high-viscosity starch is high can be solved.

Description

technical field [0001] The invention relates to the technical field of glass fiber yarns, in particular to a starch type textile sizing agent and a preparation method thereof. Background technique [0002] Sizing agent is an indispensable material in glass fiber drawing and weaving. It plays the role of making fibers bond, bundle, lubricate and wear-resistant, and eliminate static electricity. Textile sizing is one of many types of sizing. Textile sizing has good textile processing properties such as drawing, twisting, plying, warping, and weaving. Starch-type textile sizing agent works through optimized compounding, and its main components include starch, oil, coupling agent, cationic lubricant, plasticizer, auxiliary film-forming agent, bactericide and defoamer, etc. The bundle adhesion of starch-based textile sizing depends on the film-forming agent in the raw material composition, so starch and auxiliary film-forming agents have the greatest impact on starch-based texti...
