Problems solved by technology

[0006] In addition, the vegetable oil used in the traditional wood wax oil is a pure natural vegetable oil, which lacks groups that can react with the hydroxyl groups in the wood, so it can only be physically adsorbed on the surface of the wood, and cannot be chemically combined with the wood , and therefore cannot fundamentally reduce the hygroscopicity of wood

Abstract

The invention provides an epoxy vegetable oil / wax composite emulsion wood waterproofing agent which is commonly composed of epoxy vegetable oil and wax in order to solve the technical problems. A complete hydrophobic layer is formed on the surface of a wood cell wall by utilizing the epoxy vegetable oil and the surface is modified through the wax to construct a double-layered hydrophobic structure, so that the hydrophobic property of wood is remarkably improved; meanwhile, the hygroscopicity of the wood is radically reduced by utilizing the reactivity of the epoxy vegetable oil and a hydrophilic group, i.e., hydroxyl, on the wood, so that the size stability and corrosion resistance of the wood are improved.

Description

technical field [0001] The invention relates to the field of wood waterproofing agents, in particular to a preparation method of an epoxy vegetable oil / wax composite emulsion wood waterproofing agent. Background technique [0002] The invention relates to the combination, preparation and application of an epoxy vegetable oil / wax composite emulsion wood waterproofing agent. In the method, vegetable oil and molten vegetable wax are mixed, and then emulsified to prepare a stable and efficient epoxy vegetable oil / wax composite emulsion wood waterproofing agent agent. The waterproofing agent can significantly improve the hydrophobicity, dimensional stability and corrosion resistance of wood. [0003] As an industrial and domestic material, wood is closely related to national economic construction and human life, and has many excellent qualities, such as high strength-to-weight ratio, low processing energy consumption, low environmental pollution, recyclable utilization, and good...
