Treating compound special for high-performance cord threads and method for preparing same

Abstract

The invention discloses a treating compound special for high-performance cord threads and a method for preparing the same, wherein the treating compound comprises the following components: polypropyleThe invention discloses a treating compound special for high-performance cord threads and a method for preparing the same, wherein the treating compound comprises the following components: polypropylene emulsion, polyvinyl alcohol, lubricant, coupling agent, glacial acetic acid, defoamer, and the balancing of water. The method comprises the following steps: firstly, adding certain amount of room-tne emulsion, polyvinyl alcohol, lubricant, coupling agent, glacial acetic acid, defoamer, and the balancing of water. The method comprises the following steps: firstly, adding certain amount of room-temperature deionized water into a preparation tank, stirring the materials evenly and mechanically; secondly, adding hot water to dilute the polyvinyl alcohol, and adding the diluted polyvinyl alcoholemperature deionized water into a preparation tank, stirring the materials evenly and mechanically; secondly, adding hot water to dilute the polyvinyl alcohol, and adding the diluted polyvinyl alcohol into the preparation tank; and thirdly, dissolving the lubricant with warm water, and when the lubricant is diluted well completely, adding the glacial acetic acid to certain amount of water, hydrolyinto the preparation tank; and thirdly, dissolving the lubricant with warm water, and when the lubricant is diluted well completely, adding the glacial acetic acid to certain amount of water, hydrolyzing the coupling agent, and stirring the mixture continuously; and adjusting the pH value of a solution to 6.5, and then adding the defoarmer into the preparation tank directly. The treating compoundzing the coupling agent, and stirring the mixture continuously; and adjusting the pH value of a solution to 6.5, and then adding the defoarmer into the preparation tank directly. The treating compoundcan endow yarns with good convergence to ensure the smooth progress of glass fiber drawing, and good degradation performance to ensure that in the degrading process the wear of the original yarn is l can endow yarns with good convergence to ensure the smooth progress of glass fiber drawing, and good degradation performance to ensure that in the degrading process the wear of the original yarn is less, the hair feather is less and the permeability with an RFL dipping latex is good so that the comprehensive performance of products is high.ess, the hair feather is less and the permeability with an RFL dipping latex is good so that the comprehensive performance of products is high.

Description

technical field [0001] The invention relates to a sizing agent, in particular to a special sizing agent for cords with high textile performance and good combination with RFL emulsion and a preparation method thereof. Background technique [0002] The sizing agent is a crucial production material in the process of glass fiber drawing, desolvation and bonding with the subsequent resin, and directly plays a decisive role in the quality of the glass fiber product. If the quality of the sizing agent cannot be guaranteed, the yarn The thread may break and fly during the wire drawing process; hairiness may occur during the unwinding process; and poor soaking may occur during the combination with RFL impregnated latex. Contents of the invention [0003] The invention provides a high-performance special sizing agent for cords and a preparation method thereof. [0004] In order to solve the above technical problems, the high-performance special sizing agent for cords of the present...
