The present invention relates to a liquid-state temporary reinforcing material, a preparation method therefor and an application thereof. The liquid-state temporary reinforcing material comprises a reinforcing material and a crystallization inhibitor; the reinforcing material is selected from molecules of any two or more of menthol, menthone, menthol ester and menthol ether, and the content of the crystallization inhibitor is less than 50 ppm. For the liquid-state temporary reinforcing material of the present invention, the menthol and the derivatives of the liquid-state temporary reinforcing material are integrally mixed together to form the composite material for temporary reinforcing, the composite material being liquid and volatilization-controllable at room temperature. Thus, the temporary reinforcing requirements for extracting cultural relics at an archaeology excavation site may be met, and the material is convenient to use.

Wood markers and processes for durably marking and subsequently identifying both original grain wood products and wood-plastic composite products. The wood marker can be dispersed beneath the surface of the wood, where it is protected from the elements and may endure years of exposure to the elements. The wood marker is compatible with state-of-the-art pressure-treating processes and may subsequently be detected for authentication purposes by known analytical methods.

A multifunctional broad spectrum antimicrobial composition is described. The composition can be incorporated into a wood preservative, or used as an additive to provide antimicrobial properties to water-based wood coatings. The composition is a concentrated water-miscible emulsion containing 3-iodo-2-propynyl N-butylcarbamate (IPBC), carbendazim (BCM) and propiconazole (PPCZ), and has antimicrobial activity against a wide variety of fungal organisms, including surface molds, blue stain fungi and wood rotting fungi. The composition can act as an in-can preservative and is useful for antimicrobial protection of wood and wood-based substrates.
