  • Patent number: 10106931
    Abstract: A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.

  • Patent number: 7563826
    Abstract: Emulsions are provided which are useful in imparting water-resistance to lignocellulosic products. In one embodiment, the emulsions contain a nonsaponifiable wax, a saponified wax, an alkyl phenol component, a dispersant/surfactant such as a salt of polynaphthalenesulfonic acid, and a carboxymethylcellulose. Such emulsions may be added to hot, even boiling, water without the emulsion separating of curdling. Various embodiments are stable for extended periods of time when stored at room temperature, do not require the addition of a preservative biocide to avoid contributing to biodegradation in a lignocellulosic product. The emulsions are pourable liquids at room temperature. Optionally, the emulsions may be added to lignocellulosic products with a preservative to inhibit the preservative from leaching out.
