Abstract
The invention discloses a composite efficient fire retardant used for wood fire retardation and containing phosphorus, nitrogen and boron. The composite efficient fire retardant comprises, by mass, 20-40% of urea, 10-30% of phosphoric acid, 5-20% of boric acid, 2-8% of formaldehyde, 5-15% of nanometer zinc borate, 3-8% of ammonium molybdate, 0.5-3% of sodium benzenesulfonate and 0.1-1% of pentaerythritol. Compared with fire retardants in the invention, the composite efficient fire retardant containing phosphorus, nitrogen and boron fire retardation components has good fire retardation, has improved fire retardation and smoke inhibition performances due to the addition of nanometer zinc borate, ammonium molybdate and pentaerythritol, and has improved wood treatment dipping depth through the addition of sodium benzenesulfonate as a surfactant.
Description
Technical field
The present invention relates to technical field of flame retardant, specifically a kind of phosphorus-nitrogen containing boron composite highly effective fire retardant of fire-retarding of wood.
Background technology
One of material the most important and the most frequently used with life produced by timber, but timber very easily burns, and there is larger disaster hidden-trouble.So carrying out flame treatment to timber is that Now Domestic is outer all in the problem of research, and adopt fire retardant to timber pickling or coating process often.
Summary of the invention
The object of the present invention is to provide a kind of phosphorus-nitrogen containing boron composite highly effective fire retardant of fire-retarding of wood of impregnation process.
The technical solution adopted for the present invention to solve the technical problems is: a kind of phosphorus-nitrogen containing boron composite highly effective fire retardant of fire-retarding of wood, its component by mass percent proportioning is: urea 20% ~ 40%, phosphatase 11 0% ~ 30%, boric acid 5% ~ 20%, formaldehyde 2% ~ 8%, nano-zinc borate 5% ~ 15%, ammonium molybdate 3% ~ 8%, benzene sulfonic acid sodium salt 0.5% ~ 3%, pentaerythrite 0.1% ~ 1%.
The mass percent concentration of described phosphoric acid is 70% ~ 90%.
The preparation method of the phosphorus-nitrogen containing boron composite highly effective fire retardant of a kind of fire-retarding of wood of the present invention is: take each component by mass percent proportioning, again by urea, phosphoric acid, boric acid mixing, be heated to 90 DEG C ~ 130 DEG C, react after 5 ~ 30 minutes, be cooled to less than 65 DEG C, add formaldehyde, be warming up to 70 DEG C ~ 90 DEG C, react after 20 ~ 60 minutes, be cooled to room temperature, add nano-zinc borate again, after ammonium molybdate, benzene sulfonic acid sodium salt, pentaerythrite mix, drying, screening, namely obtain the present invention.
The invention has the beneficial effects as follows, compared with prior art, the present invention contains the flame-retardant composition of phosphorus, nitrogen, boron, there is good flame-retardance, and add nano-zinc borate, ammonium molybdate and pentaerythrite, further promote its flame retarding and smoke suppressing properties, add benzene sulfonic acid sodium salt and improve the process impregnation of timber degree of depth as surfactant.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.
A phosphorus-nitrogen containing boron composite highly effective fire retardant for fire-retarding of wood, its component by mass percent proportioning is: urea 35%, phosphoric acid 20%, boric acid 15%, formaldehyde 5%, nano-zinc borate 15%, ammonium molybdate 6%, benzene sulfonic acid sodium salt 3%, pentaerythrite 1%.Wherein, the mass percent concentration of described phosphoric acid is 70% ~ 90%.
Its preparation method is: take each component by mass percent proportioning, again by urea, phosphoric acid, boric acid mixing, be heated to 90 DEG C ~ 130 DEG C, react after 5 ~ 30 minutes, be cooled to less than 65 DEG C, add formaldehyde, be warming up to 70 DEG C ~ 90 DEG C, react after 20 ~ 60 minutes, be cooled to room temperature, add nano-zinc borate again, after ammonium molybdate, benzene sulfonic acid sodium salt, pentaerythrite mix, drying, screening, namely obtain the present invention.
