Abstract
The invention discloses a wood fire retardant, which consists of the following raw materials by weight portion: 5 to 10 portions of borax, 15 to 25 portions of ammonium polyphosphate, 0.5 to 1 portion of ammonium molybdate, 30 to 40 portions of ammonium sulfate, 30 to 40 portions of diammonium phosphate, 15 to 25 portions of reinforcing agent, and 860 to 1,270 portions of water (adding or no adding), wherein the reinforcing agent consists of 30 to 45 portions of phthalic anhydride, 65 to 70 portions of triethanolamine, and 130 to 140 portions of water. A method for producing the fire retardant comprises the steps of: 1, the preparation of the reinforcing agent; 2, the preparation of the fire retardant; and 3, the preparation of a fire-retardant impregnation liquid during the concrete impregnation application, wherein the last step can be prepared as required. The fire retardant releases less harmful gas and smoke smog in combustion environment, has small pollution to the atmosphere and simple production technology, and is favorable for improving the bonding strength after the reinforcing agent is added in the fire retardant.
Description
Technical field
The present invention relates to the wood fire retardant that a kind of organic matter and inorganic matter are formed.
Background technology
CN1294172 discloses Mr.'s Qiao Wanjun " efficient flame-retarding agent " patent application technology, and this fire retardant decomposites NH in high temperature
3, N
2, H
2, CO
2, gas such as CO, thereby have iris action fire-retardant to combustible, but these gases are harmful, polluted atmosphere.CN101306545 discloses Kunming University of Science and Technology's " a kind of timber group combustion agent and preparation method thereof " patent application technology, in fire retardant, added surfactant, reduce the surface tension of retardant solution, to increase the infiltration degree of depth of medicine, improve carrying drug ratio and enlarge flame retardant effect, but need to adopt the technology such as composite of synthetic, fire retardant of synthetic, the melamine phosphate salt of carbamidophosphoric acid salt, operations such as cooling, filtration, crystallization, oven dry, pulverizing are also respectively arranged, technology is complicated.The composition that contains ammonium in many wood fire retardants, ammonium can form NH having under water and the high-temperature condition
3Gas occurs with bubble form in timber, influences the bonding strength of timber, how to improve the fire retardant that the contains ammonium negative effect problem to bonding strength, does not see that so far document announcement and material object appear on the market.
Summary of the invention
At the deficiencies in the prior art, task of the present invention is that to design a kind of, technology few to atmosphere pollution simple and to little wood fire retardant and the production method thereof of bonding strength influence.
The measure of finishing above-mentioned task is: this wood fire retardant is made up of the raw material of following weight portion: 5-10 parts of boraxs, 15-25 parts of APPs, 0.5-1 part of ammonium molybdate, 30-40 parts of ammonium sulfate, 30-40 parts of diammonium hydrogen phosphates, 15-25 parts of reinforcing agents, add or do not add 860-1270 parts of water; Wherein reinforcing agent is made up of 30-45 parts of phthalic anhydrides, 65-70 parts of triethanolamines, 130-140 parts.
This fire-retarding of wood agent and process for producing same follows these steps to carry out:
(1) preparation of reinforcing agent: mix with 30-45 weight portion phthalic anhydrides, 65-70 weight portion triethanolamines, 130-140 weight parts waters, be heated to 100 ℃, the following reaction of normal pressure 20min;
(2) preparation of fire retardant: with the reinforcing agent that 5-10 weight portion boraxs, 15-25 weight portion APPs, 0.5-1 weight portion ammonium molybdate, 30-40 weight portion ammonium sulfate, 30-40 weight portion diammonium hydrogen phosphates, 15-25 weight portions are made by step (1), mixing and stirring;
(3) preparation of flame-retardant impregnating liquid; Fire retardant 1 weight portion that makes with step (2) and the water of 9 weight portions mix.
The invention has the beneficial effects as follows in burning situation produce pernicious gas and smog few, little to atmosphere pollution, production technology is simple, has added reinforcing agent in the fire retardant, the improvement of favourable bonding strength.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment: the composition that contains a large amount of boron, nitrogen, phosphorus in this fire retardant, good flame resistance, molybdenum have a favourable smoke elimination, phthalic anhydride can form phthalic acid under the effect of water and heat, under the effect of temperature and pressure, free urea in phthalic acid and the urea-modified melamine glue or methylolurea generation condensation reaction, reduced the free urea content in the glue on the one hand, by methylolurea phenyl ring is incorporated in the network structure of resin on the other hand, has improved bonding strength.Make fire-retarding of wood because of this fire retardant adopts impregnation method, various laminates, glued board, composite plate all need be glued, so the fire retardant that provides is crucial to the performance of improving bonding strength.
To form the raw material of reinforcing agent, fire retardant and weight portion thereof below is listed as follows in the mode of seven embodiment:
Embodiment 1 (consulting embodiment 1 corresponding raw material and weight portion numerical value in the table): earlier will 30 parts of phthalic anhydrides, 65 parts of triethanolamines, 130 parts of water heat to 100 ℃ after mixing, normal pressure down reaction to make reinforcing agent in 20 minutes standby.Again 5 parts of boraxs, 15 parts of APPs, 0.5 part of ammonium molybdate, 30 parts of ammonium sulfate, 30 parts of diammonium hydrogen phosphates, 15 parts of aforementioned made reinforcing agents are mixed together to stir and make fire retardant.
Or use aforementioned fire retardant 1 weight portion and 9 weight portion water for industrial use mixing and stirring again, and be mixed with flame-retardant impregnating liquid, be applied to impregnated timber.This can face to join and faces usefulness.
Embodiment 2-7: consult raw material and the heavy umber value of embodiment 2-7 in the table, make fire retardant or flame-retardant impregnating liquid with embodiment 1 same procedure.
Among seven embodiment, preferred with embodiment 1-3.
