Abstract

The invention discloses a wood preservative flame retardant and a preparation method thereof. The wood preservative flame retardant comprises the following components by mass: 15%-20% of amidinourea phosphate, 5%-8% of zinc borate, 10%-15% of diammonium hydrogen phosphate, 1%-4% of ammonium molybdate, 6%-8% of chlorothalonil, 3%-6% of disodium octoborate tetrahydrate, 2%-4% of dioctyl dimethyl ammonium chloride, 1%-3% of tetradecyl dimethyl benzyl ammonium chloride, 0.5%-2% of fatty alcohol polyoxyethylene ether, 5%-10% of nano silicon dioxide, and 20%-50% of water. The beneficial effect is that the treated wood has excellent flame retardant smoke suppression properties, broad-spectrum fungicidal and insecticidal effect, excellent antiseptic and mouldproof effect and other advantages, and is good in permeability, strong in erosion resistance, low in cost, and simple in preparation process.

Description

A kind of wood preservation fire retardant and preparation method thereof

Technical field

The present invention relates to Wooden modifying processing technology field, specifically a kind of wood preservation fire retardant and preparation method thereof.

Background technology

Timber is a kind of natural organic, has obvious biological nature, easily by biological attack such as bacterium, worm, the raw boring in sea worms, and easy firing, easily moisture absorption, this will have impact on its effect and application greatly.Along with the raising of people's living standard, the demand of timber is also increased day by day.Making full use of existing timber resources, walk Sustainable Development Road, is the only way of China's timber industry development.Carrying out the process such as anticorrosion, fire-retardant to timber, is promote normal timber life, prevent fire, save one of timber and important channel of protecting forest resources.The timber that China uses at present after antiseptic fire-retardation process is little, and mostly uses the mankind and the large traditional wood treatment agent of environmental hazard, and therefore a kind of efficient, novel wood preservation fire retardant of Study and Development is very necessary.

Summary of the invention

The object of the present invention is to provide wood preservation fire retardant that a kind of flame-retardant smoke inhibition, anticorrosion, mildew-resistant and vermins-proof effect are good and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: a kind of wood preservation fire retardant, and its component by mass percent proportioning is: guanylurea phosphate 15% ~ 20%, Firebrake ZB 5% ~ 8%, diammonium hydrogen phosphate 10% ~ 15%, ammonium molybdate 1% ~ 4%, Bravo 6% ~ 8%, four water eight Boratex 3% ~ 6%, two octyldimethyl ammonium chloride 2% ~ 4%, myristyl benzyl dimethyl ammonium chloride 1% ~ 3%, AEO 0.5% ~ 2%, nano silicon 5% ~ 10%, water 20% ~ 50%.

The preparation method of above-mentioned a kind of wood preservation fire retardant, comprises the following steps:

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

(2), guanylurea phosphate, Firebrake ZB, diammonium hydrogen phosphate, AEO, nano silicon are added in agitator, mixed on low speed 1 ~ 3min, then AEO is added, high-speed stirred 15 ~ 30min, add water again, stirring at low speed 3 ~ 5min, then ammonium molybdate, Bravo, four water eight Boratexes, two octyldimethyl ammonium chloride, myristyl benzyl dimethyl ammonium chloride is added, continue stirring 15 ~ 20min, obtain a kind of wood preservation fire retardant of the present invention.

The invention has the beneficial effects as follows, the present invention has the excellent advantage such as flame retarding and smoke suppressing properties, the sterilization and disinsection effect of wide spectrum, excellent anticorrosive mildewproof effect to process timber, and good penetrability, and resistance leachability is strong, and cost is low, and preparation technology is simple.
