Abstract

The invention discloses a slurry composition of a glass fiber yarn and a method for preparing the same, and aims to provide a slurry composition of the glass fiber yarn, which has stable slurry viscosity without preservative, less compounding ingredients and good stability. The slurry composition of the glass fiber yarn comprises the following components in proportion by weight: 2 to 5 percent of polyvinyl alcohol, 1.5 to 4.5 percent of polyethylene glycol, 0.0005 to 0.0015 percent of antifoaming agent and the balance of water. The slurry composition of the glass fiber yarn can be widely applied in the filed of manufacturing glass fiber clothes.

Description

technical field [0001] The invention relates to a size composition of glass fiber yarn and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance, and its components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. It uses stone powder as raw material to form glass fiber yarn through high-temperature melting, wire drawing, and twisting. The glass fiber yarn is then prepared, weaved, and post-treated to form glass fiber cloth. The glass fiber sizing process is mainly in the preparation part, which is to coat the glass fiber yarn with a certain amount of slurry. After padding and drying, part of the slurry penetrates into the interior of the glass fiber yarn, increasing the adhesion between the glass fibers. Therefore, the strength of the glass fiber yarn is increased, and another part of the size is coated on the surface of the glass fiber yarn to form a thin...
