Embodiment Construction

[0012] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0013] A halogen-free wood flame retardant, the composition of which is: 37% diammonium hydrogen phosphate, 30% dicyandiamide, 25% ammonium polyphosphate, 5% sodium molybdate, 2% diethanolamine, pentaerythritol 1%.

[0014] The preparation method is as follows: weighing each component according to the mass percentage ratio, adding them to a stirrer to mix uniformly, drying, pulverizing and sieving to obtain the present invention.

[0015] Adopt the halogen-free wood flame retardant of the present invention to carry out the process of fire-retardant treatment to wood as follows:

[0016] (1) Dry the wood to be treated so that its moisture content is ≤12%, and then microwave it for 10 to 30 minutes;

[0017] (2) Add water to the wood flame retardant of the present invention to prepare a (mass) flame retardant solution with a concentratio...

Abstract

The invention discloses a halogen-free wood flame retardant and a process of processing wood by using the halogen-free wood flame retardant. The halogen-free wood flame retardant disclosed by the invention comprises the following components in percentage by weight: 30-50% of diammonium hydrogen phosphate, 25-40% of dicyandiamide, 20-40% of ammonium polyphosphate, 2-8% of sodium molybdate, 0.5-3% of diethanol amine and 0.1-1% of pentaerythritol. Compared with the prior art, the halogen-free wood flame retardant disclosed by the invention has the advantages of environment friendliness, smoke inhibition, efficiency, small use amount and the like, and is simple in process, easy to industrialize, clean and free of pollution in production, relatively low in cost and convenient to use. Moreover, the effect for flame retardant treatment on the wood by using the flame retardant is good, the immersion depth is great, the time is short and the loss rate of the mechanical property on the wood is less than or equal to 15%. Therefore, the halogen-free wood flame retardant disclosed by the invention has the good practical value and market prospect.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to a halogen-free wood flame retardant and a process for treating wood with the flame retardant. Background technique [0002] Wood is widely used in the fields of construction, transportation, furniture and interior decoration, etc., but its flammability can easily bring fire hazards, causing casualties and property losses. Treating wood with suitable flame retardants will further broaden the scope of wood use and maintain It is of great significance to ensure the safety of people's property and ensure the stable growth of the national economy. Wood flame retardant is a chemical agent that can improve or strengthen the fire resistance of wood. The wide application of wood flame retardants in wood and wooden products greatly reduces the hidden danger of fire. Existing wood flame retardants mainly include: flame retardants containing compounds or mixtures of phosphoru...
