Abstract
The invention discloses a timber flame retardant for preparation of flame-retardant timber through impregnation. The flame retardant is composed of the following components in percentage by weight: 30 to 50% of polyammonium phosphate, 20 to 40% of dicyandiamide, 10 to 20% of ammonium dihydrogen phosphate, 5 to 15% of sodium tetraborate, 2 to 8% of ammonium molybdate, 0.5 to 3% of triethanolamine, and 0.1 to 1% of pentaerythritol. Compared with the prior art, the timber flame retardant has the advantages of no halogen, smoke suppression, environment-friendliness, good flame retardant effect, simple preparation technology, and low cost.
Description
Technical field
The present invention relates to wood fire retardant technical field, specifically a kind of wood fire retardant fire-retardant for timber pickling.
Background technology
Timber is widely used in fields such as building, communications and transportation, furniture and interior decorations, but its combustibility easily brings disaster hidden-trouble, cause casualties and property loss, adopt suitable fire retardant process timber to widening the timber scope of application further, safeguarding people's property safety, ensureing that notional economic stability growth has great importance.Wood fire retardant process timber can be divided into surperficial coating processing and impregnation process two kinds according to treatment process.Surface coating is on the timber of in the end machine-shaping and product surface thereof, coating fire retardant or anti-flaming dope, or pastes incombustible on its surface, is reached the fire-retardant object of heat insulation oxygen barrier by protective layer.The advantage of surface coating is less, easy to operate on the physical and mechanical property impact of timber, and equipment is simple, but shortcoming is that fire resistance disappears immediately once protective layer is damaged.The another kind of method of fire-retarding of wood process is impregnating process, is the impregnation process of after fire retardant being mixed with the aqueous solution, timber being carried out to certain hour.Lumber flame-retardant impregnating process is applicable to various timber.Along with the progress of society, the requirement of people to wood fire retardant is more and more higher, low cost, non-halogen, Non-toxic, Composite and press down a kind of new development trend that fuming becomes wood fire retardant.
Summary of the invention
The object of the present invention is to provide a kind of low cost, Halogen, press down the wood fire retardant fire-retardant for timber pickling of cigarette, environmental protection.
The technical solution adopted for the present invention to solve the technical problems is: a kind of wood fire retardant fire-retardant for timber pickling, and its component by mass percent proportioning is: APP 30% ~ 50%, dicyandiamide 20% ~ 40%, ammonium dihydrogen phosphate (ADP) 10% ~ 20%, sodium tetraborate 5% ~ 15%, ammonium molybdate 2% ~ 8%, triethanolamine 0.5% ~ 3%, pentaerythrite 0.1% ~ 1%.
The preparation method of a kind of wood fire retardant fire-retardant for timber pickling of the present invention is: content takes each component by mass percentage, adds in agitator and fully mixes, and after drying, pulverizing, drying, obtains the present invention.
The invention has the beneficial effects as follows, compared with prior art, the present invention has Halogen, presses down the advantages such as cigarette, environmental protection and good flame retardation effect, and preparation technology is simple, and cost is low.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with concrete preferred embodiment.
For the wood fire retardant that timber pickling is fire-retardant, its component by mass percent proportioning is: APP 40%, dicyandiamide 25%, ammonium dihydrogen phosphate (ADP) 15%, sodium tetraborate 10%, ammonium molybdate 6%, triethanolamine 3%, pentaerythrite 1%.
Its preparation method is: content takes each component by mass percentage, adds in agitator and fully mixes, and after drying, pulverizing, drying, obtains the present invention.
Claims (2)
1. one kind for the fire-retardant wood fire retardant of timber pickling, it is characterized in that, its component by mass percent proportioning is: APP 30% ~ 50%, dicyandiamide 20% ~ 40%, ammonium dihydrogen phosphate (ADP) 10% ~ 20%, sodium tetraborate 5% ~ 15%, ammonium molybdate 2% ~ 8%, triethanolamine 0.5% ~ 3%, pentaerythrite 0.1% ~ 1%.
2. the preparation method of a kind of wood fire retardant fire-retardant for timber pickling according to claim 1, it is characterized in that, comprise the following steps: content takes each component by mass percentage, adds in agitator and fully mixes, after drying, pulverizing, drying, obtain the present invention.
