Abstract

The invention discloses a multifunctional wood flame retardant modifier comprising the following components by mass: 5%-10% of phosphoric acid, 15%-30% of urea, 1%-3% of boric acid, 4%-7%of melamine, 1%-3% of ammonium molybdate, 2%-6% of polyethylene glycol (PEG), 10%-20% of nano kaolin, 0.5%-2% of sodium di-sec-octylmal-eacesulfonate and 20%-60% of water, the vertical thickness of the nano kaolin is 20-50nm, the layer size is 300 to 500 nm, and the pH value is 7-8. The multifunctional wood flame retardant modifier has the beneficial effects that the multifunctional wood flame retardant modifier has significant flame retardant effect on treated wood, and is good in permeability, strong in erosion resistance, good in dimensional stability, and obvious in strengthening and toughening effect.

Description

Multi-functional timber flame-proof modifier

Technical field

The present invention relates to wood treatment agent technical field, specifically a kind of multi-functional timber flame-proof modifier.

Background technology

Timber and goods thereof are widely used in interior decoration, Furniture manufacture, building construction and extraneous adornment, these materials belong to combustible material, pole fire hazardous, and expand with wet and contract with dry, dimensional stability are poor, how to improve the problem that the anti-flammability of material and dimensional stability have become whole world extensive concern.At present, prevent the most popular method of timber and goods breaking out of fire thereof from being use fire retardant in these materials, these fire retardants are mostly based on compounds such as phosphorous, nitrogen, boron, aluminium and halogens.Inorganic combustion inhibitor owing to having good flame resistance, do not produce toxic gas, do not separate out, non-volatile, cheap, wide material sources, security high and be used widely; Phosphorus-nitrogenated flame retardant has fire-retardant synergy, reduces decomposition temperature, increases the generation of charcoal, reduces the generation of imflammable gas and reduces the effects such as heat.Although these fire retardants are used for Wooden modifying process can play good flame retardant effect, it is comparatively single to there is performance in great majority, bad to the permeability of timber, and the problems such as leach resistance is poor, can not adapt to the flame-retardancy requirements of current high performance well.

Summary of the invention

The object of the present invention is to provide that a kind of good penetrability, resistance leachability are strong, efficient, the multi-functional timber flame-proof modifier of environmental protection.

The technical solution adopted for the present invention to solve the technical problems is: multi-functional timber flame-proof modifier, and its component by mass percent proportioning is: phosphoric acid 5% ~ 10%, urea 15% ~ 30%, boric acid 1% ~ 3%, melamine 4% ~ 7%, ammonium molybdate 1% ~ 3%, polyethylene glycol 2% ~ 6%, nano kaoline 10% ~ 20%, disecoctylmaleate sodium sulfonate 0.5% ~ 2%, water 20% ~ 60%.

Described phosphoric acid is the phosphate aqueous solution that mass percent concentration accounts for 80wt% ~ 90wt%.

The longitudinal thickness of described nano kaoline is 20 ~ 50nm, and lamella is of a size of 300 ~ 500nm, and pH value is 7 ~ 8.

The preparation method of above-mentioned multi-functional timber flame-proof modifier, comprises the following steps:

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

(2), phosphoric acid is added in reactor, heat by 50 ~ 120r/min stirring at low speed, when temperature rises to 50 DEG C ~ 60 DEG C, add urea, stirring at low speed is even, when continuing to be warming up to 90 DEG C ~ 120 DEG C, add boric acid, slowly be warming up to 180 DEG C ~ 220 DEG C again, keep 1 ~ 3h, then heating is stopped, in time naturally cooling to 60 DEG C ~ 80 DEG C, add polyethylene glycol, nano kaoline, disecoctylmaleate sodium sulfonate and water, and by 1500 ~ 1800r/min high-speed stirred, 20 ~ 40min, then ultrasonic disperse 10 ~ 20min, when temperature is reduced to 10 DEG C ~ 30 DEG C, add melamine and ammonium molybdate again, stirring at low speed is even, namely described multi-functional timber flame-proof modifier is obtained.

The invention has the beneficial effects as follows, the present invention has significant flame retardant effect to process timber, and good penetrability, and resistance leachability is strong, excellent size stability, toughened and reinforced successful.
