Abstract

The composite fire-proof door leaf is made up through spreading polyester film on two mould plates, loading three layers of grout and two layers of glass fibre cloth, putting a wood frame on levelled grout, putting polystyrene board in wood frame and compacting, reverse putting another mould plate on the frame, pressing with 4-5 tons of pressure for 6 hr, demoulding, trimming, coating a layer of grout on frame and curing. Said grout is prepared with magnesium oxide, magnesium chloride solution, precipitated calcium carbonate, saw dust, hydrochloric acid, trisodium phosphate, etc.

Description

The present invention relates to a kind of sheet, particularly a kind of composite fire-proof door leaf and processing technology thereof.

Existing door-plate is generally all used the timber manufacturing, and this not only wastes timber, and intensity is not high, easy deformation.The door-plate that also has some to adopt other synthetic materials to make, but all because of not enough intensity, can not prevent fires, anticorrosion, protection against the tide etc., and processing technology is complicated and can not get applying.

The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and a kind of intensity height, not yielding, fire retardant anticorrosion, the simple composite fire-proof door leaf of manufacturing process and processing technology thereof are provided.

Purpose of the present invention can reach by following measure: the present invention includes yoke, polyphenyl plate, glass fabric, mylar, slurry, calculate to make one square metre of door sheet, slurry is got 1.2~1.5g, OP10 by magnesia 4.2~4.6Kg, magnesium chloride solution 4.5~4.9Kg, precipitated calcium carbonate 0.6~1Kg, saw foam 0.4~0.6Kg, hydrochloric acid 2.3~2.7g, tri-sodium phosphate 20~24g, iron edge 280~320g, emulsifier os 15 and is got that 0.09~1.1g, dispersing agent NNO get 3.3~3.7g, NF4 gets 3.3~3.7g.Calculate to make a square meter door sheet, its processing technology is: prepare slurry, spread mylar at two Die and mould plates, on mylar,, keep flat yoke and positive angle on the slurry of a Die and mould plate strickling therein with three layers of slurry and two layers of glass fabric tiling, lie in the wooden frame polyphenyl plate and compacting, with another piece Die and mould plate flat lift to turn over be buckled on the yoke, with 4~5 tons of pressure timber is pressed molding in about 6 hours, then side cut, scraping the last layer slurry, get final product after the maintenance on yoke four limits.

Purpose of the present invention can also reach by following measure: get magnesia 4.4Kg, magnesium chloride solution 4.7Kg, precipitated calcium carbonate 0.8Kg, saw foam 0.5Kg, hydrochloric acid 2.5g, tri-sodium phosphate 22g, iron edge 300g, emulsifier os 15 in the slurry and get 1.35g, OP10 and get 0.1g, dispersing agent NNO and get 3.5g, NF4 and get 3.5g for best.Preparation is diluted to 25 ° of concentration with magnesium chloride solution during slurry, and emulsifier, each personal 10g boiling water of dispersing agent are dissolved it, all slurries is poured into to stir get final product.

The present invention has following advantage compared to existing technology:

1, big, indeformable, anti-aging, the fire prevention of energy conservation, intensity height, hardness, moistureproof, anticorrosion, sound insulation, insulation, bright and clean attractive in appearance, can bore, can follow closely, can saw, can dig, nontoxic, cheap.

2, technology is simple, and is easy to manufacture, can be processed into the door sheet of all size by customer requirements.

The present invention is described in further detail below in conjunction with accompanying drawing (embodiment):

Embodiment one:

Calculate to make 1.6 square metres (promptly the area of a door sheet is 2.0 * 0.8 meters) door sheet, get timber 0.015m 3Make yoke and lock wooden unit, and get 0.9 * 7.0 square metre of thick 10 * 10 order glass fabric of 0.2mm, and 1.3 square metres of polyphenyl plate (thick 32~36mm), 4.6 square metres of the thick mylars of 0.07mm, slurry, latex 100g, 10 pieces of iron nails (fixedly yoke usefulness).Yoke is provided with two lock wooden units; Polyphenyl plate is cut into needed specification polylith, and its thickness should be consistent with yoke thickness, is about 3.2~3.6cm; And slurry adopts magnesia 4.4Kg, magnesium chloride solution 4.7Kg, precipitated calcium carbonate 0.8Kg, hydrochloric acid 2.5g, saw foam 0.5Kg, tri-sodium phosphate 22g, iron edge 300g, emulsifier os 15 to get 1.35g, OP10 to get 0.1g, dispersing agent NNO and get 3.5g, NF4 and get the 3.5g preparation.Process for preparation is: magnesium chloride solution is diluted to 25 ° of (when referring to 20 ℃, temperature can suitably improve concentration when low) concentration; Emulsifier, each personal 10g boiling water of dispersing agent are dissolved it; All slurries are poured into to stir in the agitator get final product.When making the door sheet, on two Die and mould plates, spread mylar,, during every layer of making, all need slurry is wipeed off with scraper plate at mylar three layers of slurry of tiling and two layers of glass fabric; Keep flat yoke and positive angle on the slurry of a Die and mould plate strickling therein; Polyphenyl plate is lain in the wooden frame, and compacting; Again another piece Die and mould plate is put down to lift to turn over and be buckled on the yoke; With the pressure device of 4~5 tons of pressure the door sheet is pressed molding after about 6 hours; Excise burr with bead cutter, scrape last layer slurry (fire prevention of monoblock door sheet needs) again on yoke four limits; Maintenance can be dispatched from the factory after 28 days.The physical property of the composite fire-proof door leaf after the moulding is: rupture strength>3000N; Impact strength>100 time (10Kg heavy sand bag, drop 100cm); Air sound transmission loss>30dB; Moisture content<14%; Freeze every property 〉=25 time (circulation) fireproof performance: product is placed on the naked light do not burn; Planeness≤± 1.0mm, the length and width error :≤± 5.0mm; Weight: 0.8 * 1.6, the heavy 15.3Kg of thick 36mm door sheet, 0.8 * 1.6m, the heavy 15.8Kg of thick 38mm door sheet, 0.8 * 1.6m, the heavy 16.4Kg of thick 40mm door sheet.
