Embodiment 1

[0011] A kind of wood flame retardant, its components are proportioned by mass percentage: 30% amidinourea phosphate, 20% diammonium hydrogen phosphate, 15% boric acid, 5% ammonium molybdate, 10% sodium octaborate, 20% silica sol %, the silica content in the silica sol accounts for 20wt% to 30wt%.

[0012] Preparation method: Weigh each component according to the weight ratio, then mix phosphoguanyl urea, diammonium hydrogen phosphate, boric acid, ammonium molybdate and sodium octaborate evenly, then add silica sol and stir for 10-15 minutes, then ball mill for 1-20 minutes 2h, to make a uniform and stable mixture to obtain a wood flame retardant of the present invention.

Embodiment 2

[0014] A kind of wood flame retardant, its components are proportioned by mass percentage: 20% amidinourea phosphate, 15% diammonium hydrogen phosphate, 8% boric acid, 2% ammonium molybdate, 5% sodium octaborate, 50% silica sol %, the silica content in the silica sol accounts for 20wt% to 30wt%.

[0015] The preparation method is the same as in Example 1.

Abstract

The invention discloses a wood fire retardant which comprises the following components by mass: 20%-30% of amidinourea phosphate, 15%-20% of diammonium phosphate, 8%-15% of boric acid, 2%-5% of ammonium molybdate, 5%-10% of sodium octoborate, and 20%-50% of silica sol, and the silica content in the silicon sol is 20wt%-30wt%. The beneficial effect is that the wood fire retardant has the advantages of flame retardance of the amidinourea phosphate, diammonium phosphate, boric acid and silicon compound, smoke inhibition property of the ammonium molybdate, anti erosion performance of the silica sol, and corrosion resistance of the sodium octoborate,. The flame retardant smoke inhibition performances are excellent, the anti erosion performance is significant, and the anti-corrosion effect is good.

Description

technical field [0001] The invention relates to the technical field of wood modification treatment, in particular to a wood flame retardant. Background technique [0002] Wood is a combustible material and presents a high fire hazard. With the continuous increase in the amount of wood used in furniture, interior decoration and even building structures, and the continuous concentration of urban population, wood fires have occurred frequently in recent years, and the loss of life and property caused by them is even more immeasurable. Therefore, people have fire protection for wood. The requirements for flame retardancy are also getting higher and higher. Wood flame retardant is a chemical agent that can improve or strengthen the fire resistance of wood. However, most of the wood flame retardants on the market have relatively single performance, and their flame retardant effect is not ideal, and some wood flame retardants are relatively acidic, which is easy to cause corrosio...
