Alkylphenol Modified Phenolic-Latex Film and Effect of Humidity and Temperature on Tensile Property of Coating Fiberglass

Abstract:

Phenolic-latex film is used to coat on fiberglass surface to protect and supply fiberglass an intensive and adhesive coating for reinforcing fiber/rubber composite purpose. A series of p-alkylphenol was introduced to modify the hydrophobicity of resorcinol- formalin-latex (RFL) film surface and to prepare a p-alkylphenol-resorcinol-formalin-latex (ARFL) film, which alkyl carbon number was 1, 4, 9, 12, respectively. The surface characteristic of ARFL films was evaluated by Fourier transform spectra (FTIR) and contact angle and X-ray photoelectron spectroscopy (XPS) analysis. The surface micrograph of fiberglass pulled from H-sample was observed by scanning electron microscope (SEM). The best hydrophobicity was obtained on the nonylphenol-resorcinol- formalin-latex (NRFL) film. A better adhesion was gained for NRFL coated fiberglass comparing to RFL one. The effect of temperature and humidity on the tensile property of coated fiberglass was also discussed. The shelf life of NRFL-coated fiberglass was prolonged to six weeks under hot and humidity weather. The discussed coating may be popularized to other fiber surface to lower the effect of moisture.
