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

A kind of halogen-free flame retardants of improved wood

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of halogen-free flame retardants of improved wood.

Background technology

Timber and goods thereof have extensively universal in household and public place, in the last few years, along with people are to the pay attention to day by day of household and public place fire safety and fire block articles, exploitation has the timber of fire-retardant fireproof function and goods thereof has become the target that people pursue.Wood fire retardant is a kind of chemical agent that can improve or strengthen timber resisting combustibility, existing wood fire retardant miscellaneous is applied to Wooden modifying process at present, but due to the component of each fire retardant each, its treatment effect also has very large gap, not yet can reach the ideal effect of expection; And some fire retardant contains harmful components, all harmful effect can be produced to human body and environment.Phosphorus flame retardant occupies critical role in each based flame retardant, because it has the advantages such as low cigarette, nontoxic, Halogen, meets the developing direction of fire retardant, will have good development prospect.

Summary of the invention

The object of the present invention is to provide the halogen-free flame retardants of the improved wood that a kind of function admirable, good penetrability and cost are low.

The technical solution adopted for the present invention to solve the technical problems is: a kind of halogen-free flame retardants of improved wood, and its component by mass percent proportioning is: guanyl-urea-phosphate 20% ~ 30%, water-soluble poly ammonium phosphate 15% ~ 20%, Firebrake ZB 5% ~ 10%, pentaerythrite-volution diphenyl phosphoester 2% ~ 10%, pentaerythrite 2% ~ 5%, ammonium molybdate 1% ~ 4%, Ludox 25% ~ 40%, sodium pyrophosphate 1% ~ 2%, disecoctylmaleate sodium sulfonate 1% ~ 2%.

Dioxide-containing silica in described Ludox is 20wt% ~ 30wt%.

The preparation method of the halogen-free flame retardants of above-mentioned a kind of improved wood, comprises the following steps:

(1), each component is taken by weight ratio;

(2), by each component add in agitator and mix 10 ~ 30min, then add in three-roll grinder and grind 1 ~ 2h, namely obtain the halogen-free flame retardants of described a kind of improved wood.

The invention has the beneficial effects as follows, the present invention has excellent fire-retardant, antiseptic property, and smoke suppressing effect is good, and resistance leachability is good, Halogen, environmental protection, and cost is low, stable performance, is easy to promote.

Detailed description of the invention

Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.

Embodiment 1:

A kind of halogen-free flame retardants of improved wood, its component by mass percent proportioning is: guanyl-urea-phosphate 30%, water-soluble poly ammonium phosphate 15%, Firebrake ZB 10%, pentaerythrite-volution diphenyl phosphoester 10%, pentaerythrite 5%, ammonium molybdate 3%, Ludox 25%, sodium pyrophosphate 1%, disecoctylmaleate sodium sulfonate 1%, and the dioxide-containing silica in described Ludox is 20wt% ~ 30wt%.

Preparation method: (1), take each component by weight ratio; (2), by each component add in agitator and stir 10 ~ 30min, then add in three-roll grinder and grind 1 ~ 2h, namely obtain the halogen-free flame retardants of described a kind of improved wood.

Embodiment 2:

A kind of halogen-free flame retardants of improved wood, its component by mass percent proportioning is: guanyl-urea-phosphate 20%, water-soluble poly ammonium phosphate 20%, Firebrake ZB 5%, pentaerythrite-volution diphenyl phosphoester 5%, pentaerythrite 3%, ammonium molybdate 4%, Ludox 40%, sodium pyrophosphate 2%, disecoctylmaleate sodium sulfonate 1%, and the dioxide-containing silica in described Ludox is 20wt% ~ 30wt%.

Preparation method is with embodiment 1.
