Description
One, technical field
The present invention relates to a kind of PLASTIC LAMINATED, be specially the inorganic fire central layer of the fire endurance A1 grade standard of the middle first class fire door that can be up to state standards.The invention still further relates to the making method of this fireproof core board.
Two, background technology
The central layer of the Architectural Equipments such as existing fire door is mostly pearlstone central layer, although its finished product fire protection flame retarding, intensity, thermal conductivity, chemical stability, wettability power etc. are all undesirable.For this reason:
Chinese patent application discloses a kind of composite inorganic fireproof board and preparation method thereof No. 201110430913.3, and wherein, composite inorganic fireproof board, comprises heat insulation sandwich layer, is compound in respectively the strength structure layer on described heat insulation sandwich layer two surfaces; Described heat insulation sandwich layer be take inorganic adhesive as jelling agent, take heat-insulating heat-preserving material as weighting material, the laminate structure that is pressed into of gluey configuration; Described strength structure layer is the laminate structure forming take inorganic adhesive as jelling agent, through mixing gluey configuration obsession.The outstanding substantive distinguishing features that the present invention has: employing inorganic adhesive is jelling agent, mixes with heat-insulating heat-preserving material and/or light material, fortifying fibre, form the sheet material of multi-layer compound structure, that core structure possesses is lightweight, the feature of insulated fire good heat-insulation effect, and the strength structure layer on heat insulation sandwich layer two surfaces has bend resistance, feature that compressive strength is high.In addition, preparation technology is simple, is applicable to batch production, integrates efficient, quality.
Chinese patent application discloses a kind of for No. 201010510980.1 by composite fireproof plate and making method.Take inorganic fire-proof plate as substrate, paste one deck fast growing wood rotary cut venner as sandwich layer veneer at a side surface of inorganic fire-proof plate, then paste one deck high-quality natural timber rotary cut venner on the surface of sandwich layer veneer as face ply; Longitudinal texture of sandwich layer veneer is perpendicular to the length direction of inorganic fire-proof plate, and longitudinal texture of face ply is parallel to the length direction of inorganic fire-proof plate; The thickness of inorganic fire-proof plate is 3～10mm, and the thickness of sandwich layer veneer is 1.5～2.5mm, and the thickness of face ply is 0.3～0.5mm; Sandwich layer veneer is through flame-retardant impregnating processing, and face ply is through fire-retarding spray coating processing.Saved one deck high-quality face ply and tackiness agent, production cost is low, and surface decoration effect is good, and surfacing is easy to use, can sawing, nail nail, sticker and paint; Except can be used for, fire-proof wooden door manufacture, also can be used for the field such as indoor decorating, Furniture manufacture.
Chinese patent application discloses a kind of cast-in-situ fireproof material of fireproof door and manufacturing method of fireproof door No. 200910131112.X, is specifically related to the cast-in-place inorganic gelling material of a kind of fire-proof door leaf, frame.Its component comprises magnesium oxide, magnesium chloride solution, remodeling agent, staple fibre and fine coal charcoal, each component is respectively magnesium oxide 30-60% by weight, magnesium chloride solution 17-50%, remodeling agent 0.5-3%, staple fibre 0.1-1%, flyash 5-30% is mixed into aqueous inorganic coagulation material.The inorganic coagulation material that this programme uses adopts cast-in-place making, do not stick with glue and prefabricated inner core, avoid crack of the prior art, fill, the situation of material mixing inequality, fully phase out the material of the volatilization obnoxious flavour that is heated, in keel shoe, filling bag is containing the inorganic coagulation material of a large amount of bubbles, alleviate the weight of whole fire door, aspect transportation and installation, greatly raising the efficiency, and bubble has good effect of heat insulation, in fire-retardant material after pressure treatment makes to solidify, bubble further dwindles, fill without omitting, whole fire door density improves, greatly strengthen fire resistance.
But the product that above-mentioned technology is made is desirable not enough at aspects such as thermal conductivity, chemical stability, use temperature scope, wettability powers.
Three, summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, by technical renovation, development one has lightweight, thermal conductivity is low, chemical stability good, use temperature scope is wide, wettability power is little, and the inorganic fire central layer of the features such as nontoxic, tasteless, fire protection flame retarding, sound-absorbing designs a kind of making method of inorganic fire central layer simultaneously.
Basic ideas of the present invention are: water and a certain proportion of magnesium chloride proportioning are made into bittern, again with magnesium oxide, trevira, 808 glue (808 glue claim again moment seccotine, multi-purpose adhesive, that the polymkeric substance that forms with the polycondensation of non-formaldehydes material take polyvinyl alcohol is as mainly becoming the adhesive for building of membrane matrix, 808 glue are to various metals and most of nonmetal good bonding strength that all has, stable performance, nontoxic), glass bead, the composite magnesite whipping agent of JT, phosphoric acid, the raw materials such as vinylformic acid mix, process desirable fire-proof product through a whole set of operation.
Inorganic fire central layer of the present invention raw material composition is by weight percentage: water 33.9-36.7%; Magnesium chloride 11-15.6%; Magnesium oxide 44.4-47.7%; Trevira 0.29-0.52%; 808 glue 1.47-1.82%; Glass bead 2.2-2.6%; The composite magnesite whipping agent of JT 0.29-0.41%; Technical pure phosphoric acid 0.04-0.13%; Technical pure vinylformic acid 0.18-0.52%.
The length of trevira recited above is not more than 20mm, and burning-point is not less than 550 ℃.
Its making method is:
A, take raw material by weight percentage: water 33.9-36.7%; Magnesium chloride 11-15.6%; Magnesium oxide 44.4-47.7%; Trevira 0.29-0.52%; 808 glue 1.47-1.82%; Glass bead 2.2-2.6%; The composite magnesite whipping agent of JT 0.29-0.41%; Technical pure phosphoric acid 0.04-0.13%; 0.18-0.52% is for subsequent use for technical pure vinylformic acid, and prepares moulds of industrial equipment;
