The preparation method of novel wooden fire prevention gate flap and doorframe
Technical field
The present invention relates to a kind of fire-proof wooden door, the preparation method of particularly a kind of novel wooden fire prevention gate flap and doorframe.
Background technology
The structure of existing fire-proof wooden door generally is to adopt the rock wool of will preventing fires, aluminium silicate wool to do the interior filling of door, and the appearance of door and doorframe are wooden combustible material and make: surperficial general wooden three decks of adopting of gate flap, doorframe is the China fir structure.The labeled door of this structure can not play anti-fire action at all, has deficiencies such as inflammable, that fireproof performance is poor, application life is short.
In order to solve the fire safety problem of fire-proof wooden door leaf and doorframe, Chinese patent CN2477797 has announced me in the water-fast gate flap of a kind of fire prevention and the doorframe utility model patent of calendar year 2001 application, its gate flap is by gate flap framework, wooden frame and stick on its outer fire-retardant fireproof plate and constitute, gate flap framework and wooden frame are used through the flitch of flame treatment and are made, vacant partially filled between gate flap framework and wooden frame has the fire proofing that is made of magnesia, magnesium chloride, alumina silicate, posts fire-retardant decoration Boeing film on the surface of fire-retardant fireproof plate; Doorframe is made of door frame and the fire-retardant fireproof plate that sticks on outside it, and framework is used by the flitch of flame treatment and made, and posts fire-retardant decoration Boeing film on the surface of fire-retardant fireproof plate.Water-fast gate flap of the fire prevention of this structure and doorframe can play certain anti-fire action, and its fireproof performance is greater than China's classification standard 72 minutes, but still can not play real anti-fire action.And in China's fire protection sector, fire-proof wooden door requires industrial grade more and more higher, and old in by the end of December, 2008 GB is about to abolish, and new standard in line with international standards is about to carry out.The labeled door grade by brought up to 90 minutes in original 72 minutes, 120 minutes, 180 minutes.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and the preparation method that provides a kind of novel wooden to prevent fires gate flap and doorframe, spraying is specifically designed to the novel fireproof paint of fire prevention series of products on it, has high-strength fire-retardant performance and remarkable water resistance, and prolong application life greatly.
Technical scheme of the present invention is: the preparation method of a kind of novel wooden fire prevention gate flap and doorframe, gate flap is made up of the filling block of whole skeleton made from dry timber and skeleton the inside, the counter-fire face of gate flap and the fiery face of the back of the body are coated with novel fireproof paint, and thickness is 3-5mm; Doorframe is made up of top slat iron and the vertical skeleton made with dry timber, and the counter-fire face of doorframe and the fiery face of the back of the body are coated with novel fireproof paint, and thickness is 3-5mm.
Gate flap four sides up and down is coated with novel fireproof paint, and thickness is 3-5mm.
The gate flap filling block is filled in the whole skeleton after mixing novel fireproof paint with scoot.
The periphery of doorframe all is coated with novel fireproof paint, and thickness is 3-5mm.
The weight proportion of each component and manufacture craft are as follows in the novel fireproof paint: kaolin 20-30 part, green stone head powder 20-25 part, potter's clay powder 5-10 part, agricultural crop straw or sawdust 5-10 part, magnesia 20-30 part, colophony powder 5-10 part, 1-28 degree magnesium chloride 50-70 part, filtration whitewash 15-25 part, soda ash 15-25 part; Its manufacture craft is:
One, the A material of preparation powdery: kaolin powder, green stone head powder, potter's clay powder, agricultural crop straw or sawdust, magnesia and colophony powder are mixed by proportioning, and stir, make the A material of powdery;
Two, the watery B material of preparation: lime is joined in the lime weight 2-3 water doubly, and stir, precipitate after 12-24 hour, make filtration whitewash; With making buck after a small amount of boiling water dissolving of the soda ash back cooling, will filter whitewash, buck and 1-28 degree magnesium chloride solution and mix, and stir by proportioning, make the watery B material of preparation;
Three, the A of powdery material and watery B material are mixed, stirred 15-30 minute, labeled door proprietary material of the present invention.
The present invention is owing to adopt as above technical scheme, and the surface is no wooden, has the high-strength fire-retardant performance, the water resistance of brilliance, prolong application life greatly, it is not only fire-retardant water-fast, but also have that high temperature does not ftracture, indeformable, fire prevention, sound insulation, heat insulation advantage.Detect through Ministry of Public Security's majesty, the labeled door grade was Duoed 150 minutes than the U.S., crossed the U.S. and Britain's level far away.Compared with prior art, have characteristics such as simple to operate, easy construction, cost are low, instant effect, fireproof paint (thick) can arbitraryly be sprayed on steel, fire-proof wooden door gate flap and the skeleton, and its fireproof performance definitely can reach optimum state.Below in conjunction with the drawings and specific embodiments detailed content of the present invention is further described.

The specific embodiment
Shown in Fig. 1-6: the preparation method of a kind of novel wooden fire prevention gate flap and doorframe, gate flap is made up of the filling block 2 of whole skeleton made from dry timber 1 and skeleton the inside, the gate flap filling block is filled in the whole skeleton 1 (as Figure 1-3) after mixing novel fireproof paint 3 with scoot, the surface of gate flap is coated with novel fireproof paint 3, thickness is 3-5mm, the gate flap of novel fireproof paint 3 will be coated with during making on the surface, put into the press seamless, after the several hrs, gate flap spontaneous curing moulding; Doorframe is made up of top slat iron 4 and the vertical skeleton 5 made with dry timber, and the periphery of doorframe all is coated with novel fireproof paint 6 (shown in Fig. 4-6), and thickness is 3-5mm.
The weight proportion of each component and manufacture craft are as follows in the novel fireproof paint: kaolin 20-30 part, green stone head powder 20-25 part, potter's clay powder 5-10 part, agricultural crop straw or sawdust 5-10 part, magnesia 20-30 part, colophony powder 5-10 part, 1-28 degree magnesium chloride 50-70 part, filtration whitewash 15-25 part, soda ash 15-25 part; Its manufacture craft is:
One, the A material of preparation powdery: kaolin powder, green stone head powder, potter's clay powder, agricultural crop straw or sawdust, magnesia and colophony powder are mixed by proportioning, and stir, make the A material of powdery;
Two, the watery B material of preparation: lime is joined in the lime weight 2-3 water doubly, and stir, precipitate after 12-24 hour, make filtration whitewash; With making buck after a small amount of boiling water dissolving of the soda ash back cooling, will filter whitewash, buck and 1-28 degree magnesium chloride solution and mix, and stir by proportioning, make the watery B material of preparation;
Three, the A of powdery material and watery B material are mixed, stirred 15-30 minute, labeled door proprietary material of the present invention.
The present invention is not limited to above-mentioned concrete structure, so long as be coated with novel fireproof paint on the surface of fire-proof wooden door leaf and doorframe, just drops within protection scope of the present invention.
