摘要:
A wood preservative composition comprising a mixture of a fungicide which is a combination of a boric acid ester, which is soluble in an organic solvent and has a sterically hindered di-alcohol or tri-alcohol group, such as trihexylene glycol biborate, an organo-iodine compound, a triazole, and a synthetic pyrethroid insecticide, said fungicide and the insecticide being present in a sufficient amount that wood treated with the wood treatment material contains fungicide and insecticide in an amount of about 1 ppm to 5000 ppm, based on the weight of the wood after treatment.
摘要:
A furan polymer impregnated wood which comprises wood impregnated with a polymerizable furfuryl alcohol monomer mixture containing at least furfuryl alcohol, stabilizing co-solvent water, and an initiator selected from the group consisting of anhydrides, acids and combinations thereof is described. A method for preparing a furan impregnated wood and uses thereof is also described.
摘要:
A method for preserving wood by contacting wood with an aqueous composition comprising a paraffin wax, at least one nonionic surfactant, and at least one organic wood preservative.
摘要:
The present invention provides wood preservative and flame retardant compositions having low leachability comprising micronized boron compounds and, optionally, one or more organic biocides which may be micronized. Also provided is a method for applying the composition to wood and wood products comprising impregnating the wood with the composition.
摘要:
A wood treatment composition having a synergistic combination of fungicides which may include two or more compounds. These combinations are shown to be especially effective in providing resistance to decay, mold and mildew when wood is treated with these combinations. Also provided is wood treated by these combinations, and a method of treatment for composite wood.
摘要:
A composition for protecting wood from decay, mildew and sapstain comprises o-phenylphenol in combination with an alkoxylated amine, wherein the weight ratio of alkoxylated amine to o-phenylphenol ranges from 1:1 to 10:1. Organic or inorganic acids may be added to enhance solubility of the alkoxylated amines.
摘要:
The invention relates to compositions and methods whereby tannin staining of a natural or synthetic lumber product can be inhibited or prevented. The compositions and methods described herein can be used in conjunction with compositions and methods for inhibiting microbial growth on or in lumber products.
摘要:
The invention relates to a method of protecting wood against light-induced degradation by treatment with an impregnation which penetrates the surface of the wood comprising a) water without an organic solvent and b) a selected sterically hindered amine N-oxyl or N-hydroxyl. A further subject is the use of a sterically hindered amine N-oxyl or N-hydroxyl for the stabilization of wood.
摘要:
The invention relates to the impregnation of wood by a solvent-free melt of modified natural resin which is solid at ambient temperature. Besides the modified natural resin, melts according to the invention may comprise wax and further additives. The melting point of the wax is preferably above 80° C. The addition of wax elevates the softening point and reduces the viscosity of the melt. Melts according to the invention do not tend to discolor even at the given temperatures of the loading treatment so that the wood treated with a melt of modified natural resin mainly retains its natural appearance.
摘要:
Applicants have discovered that amine oxides enhance the performance of azoles as fungicides and wood preservatives. Also, amine oxides have been found to provide waterproofing properties and enhance the uniform distribution and penetration of azoles into wood substrates. The present invention provides a composition comprising an amine oxide and an azole, such as a 1,2,4-triazole. The composition of the present invention may be incorporated into or be a wood preservative and waterproofing system, or agricultural product. Another embodiment of the present invention is a method for preserving and/or waterproofing a wood substrate by applying the composition to the wood substrate. Yet another embodiment is an article comprising a wood substrate and the composition of the present invention. The invention also provides a method of controlling fungi comprising applying an effective amount of the composition of the present invention to the fungi or the area on which the fungi grow.
