Description
Technical field
The present invention relates to a kind of fire retardant and preparation method thereof, more particularly to a kind of fire retardant of glued board.
Background technology
Glued board is to be peeled into veneer or by flitch slicing into veneer by juggle, then formed with adhesive gluing three layers or
The board-like material of multilayer, usually uses odd-level veneer, and forms the orthogonal gluing of machine direction of adjacent layer veneer.Because of glue
Plywood belongs to combustible material, so in the production process of glued board, to viscose glue carries out subsequently again after veneer progress flame retardant treatment
Plank, in flame retardant treatment, is typically immersed in fire retardant to handle, to improve the fire resistance of glued board by workshop section.It is swollen
Swollen type fire retardant is developed in recent years using phosphorus, nitrogen as the fire retardant that mainly forms, containing this based flame retardant it is heated when, surface energy shape
Into one layer of dense foam layer of charcoal, heat-insulated, oxygen barrier, suppression cigarette are played, and can prevent molten drop, there is good fire resistance.But in reality
In the application on border, it is found that layer of charcoal is relatively thin, flame retardant effect is not satisfactory.
The content of the invention
The object of the present invention is to provide a kind of fire retardant and preparation method thereof, which can produce the collaboration of phosphorus silicon and make
With usage amount is small and heat-resist, good flame retardation effect.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows：
A kind of fire retardant, in parts by weight, is prepared by the raw material including matching as follows：30-40 parts of phosphoric acid, di(2-ethylhexyl)phosphate
10-20 parts of hydrogen ammonium, phosphoric acid narrow 8-15 parts of base urea, 10-20 parts of melamine phosphate, 10-20 parts of aluminium dihydrogen phosphate, phosphorous poly- silicon
3-5 parts of oxygen alkane, 2-4 parts of methyl phenyl silicone resin.
Such scheme is preferable, in parts by weight, is prepared by the raw material including matching as follows：35 parts of phosphoric acid, phosphoric acid
15 parts of ammonium dihydrogen, phosphoric acid narrow 12 parts of base urea, 15 parts of melamine phosphate, 15 parts of aluminium dihydrogen phosphate, 4 parts of phosphorus containing siloxane,
3 parts of methyl phenyl silicone resin.
The invention also discloses a kind of preparation method of fire retardant, comprise the following steps,
1) phosphoric acid, ammonium dihydrogen phosphate, phosphoric acid are weighed respectively narrows base urea, melamine phosphate, aluminium dihydrogen phosphate mixing simultaneously
Stir evenly, then put into pulverizer and be crushed to 100-120 mesh；Then water is added, configuration quality concentration is the mixing of 8-12%
Liquid；
2) phosphorus containing siloxane and methyl phenyl silicone resin are weighed, pulverizer is put into respectively and is crushed to 100-120 mesh, then
Put into mixed liquor made from step 1), stir evenly up to retardant solution.
Such scheme is preferable, in step 1), weighs phosphoric acid, ammonium dihydrogen phosphate, phosphoric acid respectively and narrows base urea, melamine
Phosphate, aluminium dihydrogen phosphate are mixed and stirred for uniformly, are then put into pulverizer and are crushed to 110 mesh；Then water, configuration quality are added
Concentration is 10% mixed liquor.
Compared with prior art, the present invention has the following advantages：
Phosphorus containing siloxane and methyl phenyl silicone resin and phosphate produce phosphorus silicon synergistic effect when fire retardant is heated,
The layer of charcoal that System forming is stablized, carbon left reached more than more than 60%, heat endurance plays well heat-insulated, oxygen barrier, suppression cigarette, again
It can prevent molten drop.
