Abstract
The invention discloses a wood fire retardant with a low cost and high efficiency, wherein the preparation method of the wood fire retardant comprises the following steps: raw materials are weighed according to the components in parts by weight, are mixed uniformly and grinded for 30 min into granules with the diameters smaller than 80 meshes; the mixed materials which satisfy the granularity requirements are dried until the moisture content is smaller than 1% under the condition of lower than 120 DEG C; and finally, the efficient wood fire retardant is obtained. The wood fire retardant has low cost, a good flame retardant effect, a simple and easily-industrialized technology, less investment, cleanness and no pollution, is uniformly applied in adhesive and coating or is laid in wood shavings and wood fibers, the basic production technologies of other artificial boards and wooden products are not changed, and efficient fire retardant and smoke resistant wooden artificial boards and wooden products can be prepared.
Description
Technical field
The present invention relates to fire retardant, be specially a kind of low-cost high-efficiency wood fire retardant.
Background technology
There are the shortcoming of flame retardant effect difference in present wood fire retardant, mineral-type, and organic fire-retardant is most price height then, and pollution is arranged, and complex manufacturing is difficult for industrialization, investment is many.Each stage heat release degree difference in the combustion of wood process can be carried out the flame-retardant composition of the different operative temperatures of tool compositely, and guaranteeing all have fire retardant to play a role to some extent in each stage of combustion of wood, but the research and discovery of this respect rarely has report.
Summary of the invention
Technical problem solved by the invention is to provide a kind of low-cost high-efficiency wood fire retardant, to solve the shortcoming in the above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of low-cost high-efficiency wood fire retardant, the parts by weight of component of its raw material is:
Aluminium hydroxide 25%-30%
Magnesium hydroxide 25%-30%
Basic magnesium carbonate 20%-30%
Magnesium chloride 2.5%-3.75%
Calcium chloride 2.5%-3.75%
APP 10%-15%
Ammonium molybdate 4%-6%
A kind of preparation method of low-cost high-efficiency wood fire retardant may further comprise the steps:
The first step: the component according to weight portion takes by weighing raw material, mix and grind 30min to particle diameter less than 80 orders;
Second step: the mixed material that will meet granularity requirements is dried to moisture less than 1% being lower than under 120 ℃ of conditions; Promptly obtain efficient wood fire retardant.
Know-why of the present invention is: adopt the flame-retardant composition of the different operative temperatures of tool to carry out composite, to guarantee all have fire retardant to play a role to some extent in each stage of combustion of wood, as the 200-300 ℃ of interval that begins at timber to decompose rapidly, have that APP and basic magnesium carbonate dewater, catalysis carbon-forming plays fire retardation, 300-370 ℃ carbonization of wood stage, there are aluminium hydroxide and magnesium hydroxide to decompose dehydration at 340-390 ℃; Fire retardant of the present invention produces fire retarding effects by different mechanism, mutually coordinated, learn from other's strong points to offset one's weaknesses, as aluminium hydroxide and magnesium hydroxide dehydration heat absorption before 370,390 ℃ respectively, be converted into Al thereafter
2O
3, have the catalysis carbon-forming effect; The basic magnesium carbonate that mixes with magnesium chloride and calcium chloride takes off CO at 400-600 ℃ afterwards 200-300 ℃ of dehydration heat absorption
2APP then begins catalysis timber and becomes charcoal about 270 ℃.Be that whole flame retardant systems is existing by producing the fire retardant mechanism that non-flammable compressive gas and moisture water down imflammable gas, the fire retardant mechanism that becomes charcoal by catalysis timber is arranged again; Each component just can present best flame-retardant smoke inhibition effect according to both certainty ratios in this fire retardant prescription, and the various flame-retardant smoke inhibition components of promptly whole flame retardant systems only could perform to the synergy of non-flammable compressive gas diluting effect, catalysis carbon-forming effect, suction-operated etc. at utmost under the conditions of mixture ratios of the best.The present invention presses down the cigarette basic theories from combustion of wood characteristic and fire retardant, and the fire retardant that screen by optimizing, the different fire retardant mechanisms of tool is merged in conclusion, heat release is released coolant-temperature gage is prepared the wood fire retardant that has than high flame resistance.The CONE experiment test shows that after this added 15 parts of these fire retardants processing of weight portion, the evenly heat rate of release of timber was by 57.82kw/m
2Be reduced to 29.41 kw/m
2, total smoke release is low to moderate 20.11 by 56.21, CO and CO
2Output reduces to 0.06 and 1.39 by 0.10 and 2.68 respectively.
Beneficial effect
Flame-retardant smoke inhibition effect of the present invention is obvious, and cost is lower, cleanliness without any pollution.The present invention is directed to each stage heat release degree difference in the combustion of wood process, adopt the flame-retardant composition of the different operative temperatures of tool to carry out composite, guaranteeing all have fire retardant to play a role to some extent, thereby the synergy of the non-flammable compressive gas diluting effect, catalysis carbon-forming effect, suction-operated etc. of each component is performed at utmost in each stage of combustion of wood.All components of the present invention is inorganic substances, and key component is cheap, and fire retardant preparation technology is simple, and cost is lower, cleanliness without any pollution.Be uniformly applied to wood fire retardant of the present invention in adhesive, the coating or be paved in wooden shavings, the lumber fibre, the basic production technology of other wood-based plate and woodwork is constant, can prepare highly effective flame-retardant and press down cigarette timber wood-based plate and woodwork.
