Problems solved by technology

Wood flame retardant is a chemical agent that can improve or strengthen the fire resistance of wood. At present, various wood flame retardants have been used in wood modification, but because each flame retardant has one component, There is also a big gap in the treatment effect, and the expected ideal effect has not yet been achieved; and some flame retardants contain harmful ingredients, which will have adverse effects on the human body and the environment

Embodiment 1

[0012] A halogen-free flame retardant for modified wood, its components are proportioned by mass percentage: 30% amidinourea phosphate, 15% water-soluble ammonium polyphosphate, 10% zinc borate, pentaerythritol-spirocyclic diphenyl 10% of base phosphate, 5% of pentaerythritol, 3% of ammonium molybdate, 25% of silica sol, 1% of sodium pyrophosphate, 1% of sodium 2-2-octyl maleate sulfonate, the dioxide in the silica sol The silicon content is 20wt%-30wt%.

[0013] Preparation method: (1), weigh each component according to the weight ratio; (2), add each component into a stirrer and stir for 10-30 minutes, and then add it into a three-roll mill and grind for 1-2 hours to obtain the described A halogen-free flame retardant for modified wood.

Embodiment 2

[0015] A halogen-free flame retardant for modified wood, its components are proportioned by mass percentage: 20% amidinourea phosphate, 20% water-soluble ammonium polyphosphate, 5% zinc borate, pentaerythritol-spirocyclic diphenyl Phosphoric acid ester 5%, pentaerythritol 3%, ammonium molybdate 4%, silica sol 40%, sodium pyrophosphate 2%, sodium 2-2-octyl maleate sulfonate 1%, the dioxide in the silica sol The silicon content is 20wt%-30wt%.

[0016] The preparation method is the same as in Example 1.

Abstract

The present invention discloses a halogen-free flame retardant for modified wood, the halogen-free flame retardant comprises the following components by mass: 20%-30% of amidinothiourea phosphate, 15%-20% of water soluble ammonium polyphosphate, 5%-10% of zinc borate, 2%-10% of pentaerythritol-spiro cyclodiphenyl phosphate, 2%-5% of pentaerythritol, 1%-4% of ammonium molybdate, 25%-40% of silica sol, 1%-2% of sodium pyrophosphate and 1%-2% of sodium diethylhexyl sulfosuccinate. The beneficial effect of the halogen-free flame retardant is that the halogen-free flame retardant has excellent flame retardant and anti-corrosion performance, good anti smoking effect, good anti loss performance, is halogen-free, environmentally-friendly, low-cost, stable in performance, and easy to generalize.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a halogen-free flame retardant for modified wood. Background technique [0002] Timber and its products are widely used in household and public places. In recent years, as people pay more and more attention to fire safety and product flame retardancy in household and public places, the development of wood and its products with flame retardant and fireproof functions has become a pursuit of people. The goal. Wood flame retardant is a kind of chemical agent that can improve or strengthen the fire resistance of wood. At present, various wood flame retardants have been used in wood modification, but because each flame retardant has There is also a big gap in the treatment effect, and the expected ideal effect has not yet been achieved; and some flame retardants contain harmful ingredients, which will have adverse effects on the human body and the environment.
