Wood protecting agent and method of producing the same

Abstract

The invention discloses a wood additive and making method to solve the problem of low solubility and bad penetrability of boron system compound as wood protective in the water, which is made of 100wt% borate and 0. 1-5wt% composite surface activator. The making method comprises the following steps: 1. blending boric acid and borax evenly to place in the 25-75 deg. c environment to do solid-phased reaction; drying; obtaining the borate; 2. blending the composite surface activator and borate evenly to obtain the wood protective. The invention has the function of preservation, insect protection, termite-resistant, flame-proof and smoke inhibition, which doesn't harm human and animals without influencing the appearance, dynamics and manufacturing property of the wood.

Description

technical field

[0001] The invention relates to a wood additive and a preparation method thereof. Background technique

[0002] With the improvement of people's living standards and the development of science and technology, people's performance requirements for wood (including solid wood, wood-based panels and other wood materials) are also constantly improving, especially the antiseptic, flame-retardant and insect-proof properties of wood. At present, copper chromium arsenic (CCA) preservatives or cuproammonium quaternary ammonium (ACQ) preservatives are mostly used in the industry for wood preservative treatment. However, the use of such preservatives often causes harm to the environment. If copper chromium arsenic or cuproammonium quaternary ammonium salt is lost into the soil, it will eventually enter the surface water body, and the copper ions contained in it will be harmful to fish and other organisms in the water body; and arsenic-containing compounds are more danger...
