Description

Fire-proof magnesium composite board

Technical field

The invention belongs to fire-fighting field of new, relate to a kind of novel fireproof composite sheet, particularly relate to fire-proof magnesium composite board.

Background technology

House decoration, office are fitted up day by day prevailing, and fit up in the market and generally adopt plank or gypsum plank, plank easily catches fire, and there is potential safety hazard.Part sheet material adopts fire-resistant composite panel to substitute, but most of fire-resistant composite panel does not reach same generic request A1 level, have reach A1 level but due to the existence of chlorion, in the environment of high humidity, easily return halogen, burn into destroys other finishing materials, affects attractive in appearance, and intensity difference, water absorption rate is too high, and application life is short, and cost is also higher.For this reason, applicant has developed Novel fireproof smoke exhaust pipe composite plate (200910064677.0), carry out preliminary trial, market reaction is good, but in use the high temperature resistant deficiency of customer responsiveness in process, is easily out of shape, be badly in need of on this basis improving.

Summary of the invention

The object of the invention is to provide a kind of fireproof performance to reach not cracked, the indeformable and low-carbon (LC) of A1 level, material, environmental protection, Novel fireproof composite board that cost is low.

For realizing the object of the invention, technical scheme is as follows: this magnesia composite plate is upper and lower plane materiel with high strength magnesium calcium silicates gelling inorganic material, with Structure of Calcium Silicates composite bed for sandwich layer, with aluminum sulfate fiber mesh glass fiber, do not fire non-woven fabrics or string and be laid on outside sandwich layer, through hot pressing composite molding for reinforcing material.Wherein high strength magnesium calcium silicates cementitious material is formulated by following component: magnesium sulfate 20% ~ 25%, calcium silicates 15% ~ 20%, silicon gray fibers 3% ~ 5%, magnesia 30% ~ 40%, string 3% ~ 5%, aluminum sulfate fiber 3% ~ 5%, modifier 3% ~ 5%, swell soil 3% ~ 5%, blowing agent 3% ~ 5%, phosphatase 11 % ~ 3%, all the other are water.Wherein modifier is formulated by following component: citric acid 35%, tartaric acid 35%, methylcellulose 10%, sodium methylene bis-naphthalene sulfonate (NNO diffusant) 11%, alum 9%; Blowing agent is formulated by following component: gelatine 5%, NaOH 40%, soda ash 9%, rosin 30%, and all the other are water.Sandwich layer is formulated by following component: calcium silicates 80%, granular polystyrene 10%, acrylic acid 0.5% ~ 2%, and all the other are water; Above component is all weight percentage.

Its technique manufacturing process:

1, calcium silicates core layer component is stirred (hereinafter referred to as B material), its slurry is poured in sheet-forming machine and flattens, fiberglass gridding cloth spread by the B material flattened, does not fire non-woven fabrics or string.

2, high strength magnesium calcium silicates cementitious material component is fully stirred (hereinafter referred to as A material), its slurry is poured in sheet-forming machine, add medium-alkali glass fiber grid cloth and flatten by instruction thickness.

3, with high strength magnesium calcium silicates gelling inorganic material (A material) for upper and lower plane materiel, take calcium silicates as sandwich layer (B material), hot pressing compound makes magnesia calcium silicates fire-resistant composite panel.Then after putting into the room maintenance of railcar thermostatic curing, by regulatory specifications cutting finished product, usual thickness of slab 3mm-300mm, width is 1000mm ~ 1500mm, and long is 80mm ~ 5000mm.

Advantage of the present invention and good effect: because this material adds a large amount of silicon, sulphur, aluminium component, can tolerate 1000 DEG C of high temperature, fireproof performance reaches A1 level, and material is not cracked, indeformable.Intensity is high, sound insulation, heat insulation, more than 30 years application life, can follow closely and can dig, easy to use.Whole use inorganic material, low-carbon (LC), environmental protection, cost is low, not chloride ion-containing, and it is inflammable thoroughly to solve traditional PLASTIC LAMINATED, easily returns halogen, scum, yielding deficiency, also solves fire proofing material well to problems such as corrosions of metal.Be applicable to decorative fireproof slab, fire and smoke exhaust pipe personality board, external-wall heat-insulation material, there is fabulous promotion prospect and using value.

Detailed description of the invention

For the present invention will be described in more detail, give an actual example as follows:

Equipment: 1. mixer, 2. foaming machine, 3. mechanization sheet-forming machine, 4. mill, 5 infrared temperature control instrument, 6. fog rooms.

Example 1:

With high strength magnesium calcium silicates cementitious material for A material, with calcium silicates sandwich layer for B material, A material is formulated by following component: magnesium sulfate 20%, calcium silicates 15%, silicon gray fibers 3%, magnesia 30%, string 3%, aluminum sulfate fiber 3%, modifier 3%, swell soil 3%, blowing agent 3%, phosphatase 11 %, all the other are water.Wherein modifier is formulated by following component: citric acid 35%, tartaric acid 35%, methylcellulose 10%, sodium methylene bis-naphthalene sulfonate (NNO diffusant) 11%, alum 9%; Blowing agent is formulated by following component: gelatine 5%, NaOH 40%, soda ash 9%, rosin 30%, and all the other are water.Sandwich layer B material is formulated by following component: calcium silicates 80%, granular polystyrene 10%, acrylic acid 1%, and all the other are water; Above component is all weight percentage.

B material component is stirred, its slurry is poured in sheet-forming machine and flattens, fiberglass gridding cloth spread by the B material flattened.A material component is fully stirred, its slurry is poured in sheet-forming machine, add medium-alkali glass fiber grid cloth and flatten by instruction thickness.Be upper and lower plane materiel with A material, with B material for sandwich layer, hot pressing compound makes magnesia calcium silicates fire-resistant composite panel.Then advance and possess in the curing room of infrared temperature control device with temperature 40 DEG C ~ 70 DEG C of humidity 70%, maintenance is excision forming after 48 hours.Cut into thickness of slab 3mm-300mm according to user's request, width is 1000mm ~ 1500mm, and long is 80mm ~ 5000mm.

Example 2:

With example 1, difference is: high strength magnesium calcium silicates cementitious material (A material) is formulated by following component: magnesium sulfate 25%, calcium silicates 20%, silicon gray fibers 5%, magnesia 40%, string 5%, aluminum sulfate fiber 5%, modifier 5%, swell soil 5%, blowing agent 5%, phosphoric acid 3%, all the other are water.Sandwich layer (B material) is formulated by following component: magnesia calcium silicates 80%, granular polystyrene 10%, acrylic acid 2%, and all the other are water; Above component is all weight percentage.
