Abstract
The invention discloses an eco-friendly anti-loss timber fire retardant and its preparation method and treatment process. The eco-friendly anti-loss timber fire retardant comprises, by mass, 30-40% of ammonium polyphosphate, 5-15% of zinc borate, 15-30% of silica sol, 5-10% of antimony oxide, 2-6% of sodium molybdate, 0.5-3% of sodium dodecyl benzene sulfonate and 0.1-1% of pentaerythritol. The preparation method utilizes ammonium polyphosphate as a main agent, zinc borate, silica sol and antimony oxide as adjuvants, sodium molybdate as a smoke inhibitor, sodium dodecyl benzene sulfonate as a surfactant and pentaerythritol as a charring agent so that the eco-friendly anti-loss timber fire retardant has excellent flame retardance, smoke inhibition and loss resistance performances, is free of halogen, is environment-friendly, has a low cost, simple preparation processes and industrial production feasibility and is suitable for wood materials such as solid boards, fiberboards, shaving boards and glued boards.
Description
Technical field
The present invention relates to wood fire retardant technical field, wood fire retardant and preparation method thereof and treatment process are lost in specifically a kind of environmental protection anti-current.
Background technology
Timber is widely used in fields such as building, communications and transportation, furniture and interior decorations, but timber easy firing, once there be fire to occur, the more difficult control of the intensity of a fire, often causes the huge person, property loss.In order to reduce the disaster hidden-trouble of timber, flame treatment must be carried out to it.But in existing wood fire retardant, organic fire-retardant is expensive because releasing a large amount of toxic gas tool when it burns, and does not advocate use; Resin type fire retardant, due to fire resistance not ideal enough and exist impregnate difficulty, process material such as to darken at the problem, be not widely used.Most popular inorganic combustion inhibitor, have the advantages such as wide material sources, price are low, asepsis environment-protecting, but its leach resistance is to be improved.
Summary of the invention
A kind of environmental protection anti-current is the object of the present invention is to provide to lose wood fire retardant and preparation method thereof and treatment process.
The technical solution adopted for the present invention to solve the technical problems is: wood fire retardant is lost in a kind of environmental protection anti-current, and its component by mass percent proportioning is: APP 30% ~ 40%, Firebrake ZB 5% ~ 15%, silicon dioxide gel 15% ~ 30%, antimony oxide 5% ~ 10%, sodium molybdate 2% ~ 6%, neopelex 0.5% ~ 3%, pentaerythrite 0.1% ~ 1%.
The silica quality of described silicon dioxide gel is containing being 20% ~ 40%.
The preparation method that wood fire retardant is lost in a kind of environmental protection anti-current of the present invention is: content takes each component by mass percentage, and mixes, then drying, pulverizes, sieves, and obtains a kind of environmental protection anti-current of the present invention and loses wood fire retardant.
The step adopting a kind of environmental protection anti-current mistake wood fire retardant of the present invention to carry out fire retardant treatment process to timber is as follows:
(1), by pending drying of wood process, its moisture content≤12% is made;
(2) a kind of environmental protection anti-current mistake wood fire retardant, the present invention prepared adds water and is mixed with concentration is 15% ~ 20% fire resistant fluid;
(3), the timber of drying process is loaded in high-pressure impregnation tank, after building lid, by high-pressure impregnation tank suction to 0.03MPa ~ 0.08MPa, keep 45 ~ 90 minutes, then the fire resistant fluid of implantation step (2) in high-pressure impregnation tank, wait filling maintenance removal vacuum after 1 ~ 5 minute, slowly be forced into 1.2 ~ 1.4MPa again, and pressurize release after 2 ~ 4 hours, drain fire resistant fluid, close fire resistant fluid into and out of valve, again high-pressure impregnation tank is evacuated to 0.03MPa ~ 0.08MPa, keep 10 ~ 30 minutes, remove vacuum, take out timber;
(4), by the timber that step (3) obtains carry out drying, complete the flame treatment to timber.
The invention has the beneficial effects as follows, compared with prior art, the present invention take APP as host, Firebrake ZB, silicon dioxide gel, antimony oxide are assistant agent, and add that sodium molybdate is smoke suppressant, neopelex is surfactant, pentaerythrite is carbon forming agent, make a kind of environmental protection anti-current obtained lose wood fire retardant and there is excellent flame retarding and smoke suppressing properties and leach resistance, and Halogen, environmental protection, low cost and preparation technology are simple and easy to suitability for industrialized production etc., be applicable to the wood materials such as solid wood board, fiberboard, particieboard, glued board.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.
Wood fire retardant is lost in a kind of environmental protection anti-current, and its component by mass percent proportioning is: APP 35%, Firebrake ZB 15%, silicon dioxide gel 30%, antimony oxide 10%, sodium molybdate 6%, neopelex 3%, pentaerythrite 1%.Wherein, the silica quality of described silicon dioxide gel is containing being 20% ~ 40%.
Its preparation method is: content takes each component by mass percentage, and mixes, then drying, pulverizes, sieves, and obtains a kind of environmental protection anti-current of the present invention and loses wood fire retardant.
The step adopting a kind of environmental protection anti-current mistake wood fire retardant of the present invention to carry out fire retardant treatment process to timber is as follows:
(1), by pending drying of wood process, its moisture content≤12% is made;
(2) a kind of environmental protection anti-current mistake wood fire retardant, the present invention prepared adds water and is mixed with concentration is 15% ~ 20% fire resistant fluid;
(3), the timber of drying process is loaded in high-pressure impregnation tank, after building lid, by high-pressure impregnation tank suction to 0.03MPa ~ 0.08MPa, keep 45 ~ 90 minutes, then the fire resistant fluid of implantation step (2) in high-pressure impregnation tank, wait filling maintenance removal vacuum after 1 ~ 5 minute, slowly be forced into 1.2 ~ 1.4MPa again, and pressurize release after 2 ~ 4 hours, drain fire resistant fluid, close fire resistant fluid into and out of valve, again high-pressure impregnation tank is evacuated to 0.03MPa ~ 0.08MPa, keep 10 ~ 30 minutes, remove vacuum, take out timber;
(4), by the timber that step (3) obtains carry out drying, complete the flame treatment to timber.
