Abstract

The invention relates to a wood preservation and water repellent agent and a preparation method thereof. The wood preservation and water repellent agent comprises the following components in percentage by weight: 10-20 percent of paraffin, 5-10 percent of dry oil, 0.3-0.7 percent of medium-chain-length alcohol, 0.6-1.3 percent of fatty acid, 0.1-1.0 percent of quaternary ammonium salt, 0.1-0.5 percent of macromolecular surfactant, 1.2-2.6 percent of sorbitan tristearate, 2.7-5.5 percent of polyoxyethylene sorbitan tristearate and 68-75 percent of water. According to a paraffin and plant dry oil water-based emulsion, the dimension stability of wood in a damp environment is remarkably increased and the waterproof performance is prolonged.

Description

technical field [0001] The invention relates to an antiseptic and waterproof agent, more specifically the invention relates to a wood antiseptic and waterproof agent and a preparation method thereof, which is suitable for indoor and outdoor wood protection. Background technique [0002] There are mechanical or mechanical degradation, chemical degradation, fire, wood weathering and biological degradation, etc., among which the most important is biological degradation, which includes the harm of fungi and insects to wood. Most wood is prone to decay, blue stain, and insects due to its loose material and low density. Wood preservative treatment can eliminate the necessary conditions for the survival of wood harmful organisms, so as to achieve the purpose of protecting wood. [0003] At present, the wood preservatives such as ACQ, CCA, and CuAz used in China have no waterproof function, and most wood preservative treatments use water-soluble preservatives, but the anti-corrosi...
