preparation example Construction

[0104] The preparation method of this glass fiber direct yarn sizing agent comprises the steps:

[0105] 1S: Add 40% to 50% of the total amount of wetting agent in the container, then add the pH regulator, stir for 3 to 5 minutes, add part of the coupling agent, and stir for 20 to 30 minutes; then slowly add the remaining Coupling agent, stirring for 20 to 30 minutes, until the coupling agent is uniformly dispersed, the aqueous solution is clear, and there are no oil droplets on the surface;

[0106] 2S: Dissolve the lubricant in 5-10 times the amount of water at 40-50°C, stir and dilute it and add it to the container;

[0107] 3S: Add epoxy resin emulsion and polyurethane emulsion to the container respectively and stir evenly;

[0108] 4S: Add the remaining amount of water to the container and stir evenly.

Abstract

The invention discloses a glass fiber direct yarn impregnating compound which comprises the following components in percentage by mass: 5-12% of solid and the balance of water, wherein the percentageof the solid mass of each component in the impregnating compound in the solid mass of the impregnating compound is as follows: 5.5-20.5% of a coupling agent, 9-20% of a lubricant, 51-82% of a film-forming agent, and 2-8.5% of a pH value regulator, wherein the film-forming agent is a mixture of epoxy resin emulsion and polyurethane emulsion, and the mass ratio of the epoxy resin emulsion to the polyurethane emulsion is 1.42:1 to 4:1. After asphalt is coated with the impregnating compound, the strength is high, and various index requirements of the geogrid are met.

Description

technical field [0001] The application relates to the technical field of glass fiber reinforced composite materials, in particular to a glass fiber direct yarn sizing agent and its preparation method and application, which are mainly used in the production process of glass fiber products for civil grids. Background technique [0002] Fiberglass geogrid is an excellent geosynthetic material used for pavement reinforcement, old road reinforcement, and roadbed reinforcement. It has become an irreplaceable material in the application of dealing with reflective cracks in asphalt pavement. This product is a semi-rigid product made of high-strength alkali-free glass fiber, which is made into a mesh base material through the international advanced warp knitting process, and is surface coated. Both warp and weft have high tensile strength and low elongation, and have excellent properties such as high temperature resistance, low cold resistance, aging resistance, and corrosion resist...
