Abstract
The invention relates to a fire door. The fire door comprises a door plate and a fireproof layer and is characterized by consisting of the following formulas in parts by weight: 15 to 20 parts of tri(beta-chloroethyl) ester phosphate (TCEP), 5 to 10 parts of triethyl phosphate (TEP), 20 to 30 parts of tri(2-chloroethyl)ester phosphate (TCPP) and 10 to 15 parts of bisphenol A di(diphenyl phosphate) (BDP). When the door is on fire and is combusted, substances in the fireproof layer are rapidly carbonized, the oxygen is isolated, the combustion is prevented, the fireproof effect is obvious, the fireproof performance can reach the level of B1 (GB8624-2006), the preparation process is simple, and the production cost is low.
Description
Technical field
The present invention relates to a kind of labeled door.
Background technology
Door is used in daily life widely, the raising gradually of Along with people's awareness of the importance of fire prevention, and the fireproof performance of opposite house is had higher requirement; Also there are some labeled doors at present; Like Chinese patent: labeled door (200710093204.4), a kind of labeled door is disclosed, said door leaf comprises door leaf surrounding layer, door leaf inner sandwich layer and skeleton; The door leaf surrounding layer coats said skeleton and door leaf inner sandwich layer fully, and said door leaf surrounding layer, door leaf inner sandwich layer and skeleton are through the whole compound moulding of building; The door leaf surrounding layer is processed by inorganic fireproof material, and skeleton is processed by veneer, said door leaf inner sandwich layer adopt rock wool, expanded perlite or magnesia expanding material one or both; Doorframe adopts double-layer structure, and skin is an inorganic fireproof material, and inner core is a veneer.A kind of labeled door (201110230737.9) provides a kind of labeled door, the heat-barrier material that comprises framework and be covered in said framework surface, and said heat-barrier material comprises: metal level; Tack coat sprays or is deposited on the said layer on surface of metal; And isolation layer, spray or be deposited on the said tie layer surface; At least one surface that said heat-barrier material is covered in said framework forms insulating sandwich; The insulating sandwich that can comprise multilayer; Be filled with traditional fire proofing material between the said insulating sandwich.The isolation layer of labeled door of the present invention adopts the two sides to be coated with the steel plate of novel refractory, not only has better effect of heat insulation and very firm withstand voltage.
Above-mentioned existing labeled door, remain also its flame-retardant formulations and preparation method thereof is not carried out perfect, and complicated process of preparation, the sub-economic shortcoming of cost of production.
Summary of the invention
In order to overcome existing labeled door, remain also its flame-retardant formulations and preparation method thereof is not carried out perfect, and complicated process of preparation, the sub-economic shortcoming of cost of production, the present invention provides a kind of labeled door.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of labeled door; Comprise door-plate, fireprotection layer; It is characterized in that: the prescription of fireprotection layer constitutes; In weight fraction, tricresyl phosphate (β one chloroethyl) ester (TCEP) 15-20 part, triethyl phosphate (TEP) 5-10 part, tricresyl phosphate (2 one chloropropyl) ester (TCPP) 20-30 part, bisphenol-A two (diphenyl phosphoester) be 10-15 part (BDP).The door-plate both sides all are provided with fireprotection layer;
Make through following steps:
(1) selects suitable trees as raw material;
(2) raw material is cut, be processed into the door-plate of rectangle;
(3) with wire brush door-plate is carried out surfacing;
(4) with the fireproofing agent spary for preparing on the door-plate of handling well, natural air drying 60 minutes forms fireprotection layer, promptly gets labeled door.
The invention has the beneficial effects as follows: when door runs into fiery after-combustion, the material in the fireprotection layer becomes carbon rapidly, has completely cut off oxygen, has stoped burning, and flameproof effect is remarkable, and fireproof performance reaches B1 level (GB8624-2006).
And preparation technology is simple, and cost of production is lower.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a kind of structural representation of labeled door.
Among Fig. 1,1. fireprotection layer, 2. door-plate.
The specific embodiment
Below in conjunction with specific embodiment technical scheme of the present invention is described further, following examples are the preferred embodiments of the present invention, do not represent all technical schemes of the present invention.
Fireproofing agent makes through following method:
Embodiment 1, and in container, order adds 15 parts of esters (TCEP) of tricresyl phosphate (β one chloroethyl), 5 parts of triethyl phosphates (TEP), 30 parts of tricresyl phosphate (2 one chloropropyl) esters (TCPP), two (diphenyl phosphoesters) (BDP) 15 parts of bisphenol-A, promptly gets this fireproofing agent.
Embodiment 3, and in container, order adds 18 parts of esters (TCEP) of tricresyl phosphate (β one chloroethyl), 8 parts of triethyl phosphates (TEP), 25 parts of tricresyl phosphate (2 one chloropropyl) esters (TCPP), two (diphenyl phosphoesters) (BDP) 12 parts of bisphenol-A, promptly gets this fireproofing agent.
This labeled door makes through following steps: select suitable trees as raw material; Raw material is cut, be processed into the door-plate (2) of rectangle; With wire brush door-plate (2) is carried out surfacing; On the door-plate of handling well, natural air drying 60 minutes forms fireprotection layer (1), promptly gets labeled door with the fireproofing agent spary for preparing.
Claims (3)
1. labeled door; Comprise door-plate, fireprotection layer; It is characterized in that: the prescription of fireprotection layer constitutes; In weight fraction, tricresyl phosphate (β one chloroethyl) ester (TCEP) 15-20 part, triethyl phosphate (TEP) 5-10 part, tricresyl phosphate (2 one chloropropyl) ester (TCPP) 20-30 part, bisphenol-A two (diphenyl phosphoester) be 10-15 part (BDP).
2. according to the described a kind of labeled door of claims, it is characterized in that: the door-plate both sides all are provided with fireprotection layer.
3. according to the described a kind of labeled door of claims, it is characterized in that, make through following steps:
(1) selects suitable trees as raw material;
(2) raw material is cut, be processed into the door-plate of rectangle;
