AI Technical Summary
Existing transparent felt raw material impregnating agents have problems with insufficient interfacial compatibility and long-term weather resistance in the production of high transparency boards, resulting in light scattering, excessive haze and yellowing color, which affects the light transmittance and stability of the boards.
The wetting agent, which uses deionized water as a solvent, contains components such as water-soluble acrylic resin emulsion, modified polyurethane epoxy aqueous dispersion, polyvinyl alcohol, coupling agent, and lubricant. The wetting agent is prepared by adjusting the pH value and stirring and filtering. It is used for glass fiber precursor to ensure film-forming properties, transparency, and weather resistance.
It improves the light transmittance and interfacial bonding strength of the board, reduces haze, ensures long-term transparency stability, and improves the bundled and dispersed properties of the raw fibers during processing, avoiding yellowing and performance degradation.
