Abstract
The invention relates to a preparation method of an expanding type halogen-free organic fireproof blocking material. The preparation method comprises the following steps of: selecting raw materials of aluminium hydroxide, ceramic powder, expanding type graphite, iron oxide red, dioctyl phthalate, zinc borate, alumina silicate fibre, acrylic resin, dibutyl phthalate, polyamide resin 650, gaseous phase white carbon black and ammonium polyphosphate in a certain ratio; mixing and stirring the polyamide resin 650, the dioctyl phthalate, the gaseous phase white carbon black, the ammonium polyphosphate and the dibutyl phthalate to obtain bonded resin; placing the aluminium hydroxide, the ceramic powder, the expanding type graphite and the iron oxide red into a stirring machine to stir; adding the bonded resin and the acrylic resin into a premixed filler to mix and stir into a viscous soft ball-like substance; and placing the viscous soft ball-like substance in the above procedure into an extruder to perform extrusion molding. By the preparation method, the defect that irritant gases and smoke generated by the conventional organic fireproof blocking material under the action of a fire disaster penetrate holes to diffuse and spread all around is overcome; and the problems of damage to a human body and corrosion to equipment caused by toxic halogen acid hydrogen are solved.
Description
Described technical field
The present invention relates to a kind of fire prevention calking, relate to a kind of manufacture method of expansion type halogen-free organic fireproofing blocking material specifically.
Background technology
Present known traditional organic fire prevention calking mainly is to obtain good flame retardant resistance by adding halogen flame, though the halogen material has good flame-retardant effect, but when fire takes place, can discharge a large amount of smog and hydracid hydrogen, these smog and hydracid hydrogen can stimulate human eye and respiratory system, cause symptoms such as dizziness, stupor, expiratory dyspnea, death by suffocation, also hinder firefighter and rescue personnel's fire extinguishing and rescue work, and can cause the corrosion of electrical system switch and other metal objects.Traditional in addition organic fire prevention calking does not have the expansion function, and the toxic fumes that can not effectively stop the scene of a fire to produce when fire takes place spreads to contiguous diffusion by holes through walls such as electric wire, cables.
Summary of the invention
Contain halogen for overcoming traditional organic putty, discharge hydracid hydrogen when meeting fire, can not effectively stop because of not expanding toxic fumes that the scene of a fire produces by the slit between the slit between electric wire, cable and the organic fire prevention calking and hole through walls and the organic fire prevention calking to the deficiency that contiguous diffusion spreads, the present invention is to provide a kind of manufacture method of not halogen-containing, rate of expansion is high, close flue gas is effective, the usefulness of preventing fires is high expansion type halogen-free organic fireproofing blocking material.
The technical solution adopted for the present invention to solve the technical problems is: adopt aluminium hydroxide, zinc borate, the porcelain powder, main raw materials such as acrylic resin and expanded polystyrene veneer graphite form by extruding after mixing, its prescription prescription by weight percentage is: aluminium hydroxide 25%～40%, porcelain powder 15%～35%, expanded polystyrene veneer graphite 1%, red iron oxide 2%～8%, dioctyl phthalate (DOP) 3%～6%, zinc borate 8%～20%, aluminum silicate fiber 3%～8%, acrylic resin 10%～25%, dibutyl phthalate 3%～6%, polyamide resin 650 types 0.5%, meteorological white carbon black 0.5%, ammonium polyphosphate 0.5%.Its optimum formula is: aluminium hydroxide 32%, porcelain powder 25%, expanded polystyrene veneer graphite 1%, red iron oxide 3%, dioctyl phthalate (DOP) 5%, zinc borate 18%, aluminum silicate fiber 5%, acrylic resin 20%, dibutyl phthalate 4%, polyamide resin 650 types 0.5%, meteorological white carbon black 0.5%, ammonium polyphosphate 0.5%.
Make the technology of described expansion type halogen-free organic fireproofing blocking material, its manufacturing technology steps and processing condition are: (one) prepares binding resin: with polyamide resin 650 types, dioctyl phthalate (DOP), meteorological white carbon black, ammonium polyphosphate and dibutyl phthalate mix stirring, stir and obtain binding resin after 5～15 minutes.(2) premix filler: with aluminium hydroxide, the porcelain powder, expanded polystyrene veneer graphite, red iron oxide is put into stirrer and is stirred, and does time in advance 10～15 minutes.(3) mix to stir: binding resin and acrylic resin are joined be mixed into soft thing of viscosity in the premix filler, churning time is 5～10 minutes.(4) extrusion moulding: soft thing of the viscosity in the last process being put into forcing machine, carry out extrusion moulding, is the material homogeneity that assurance is extruded, and should extrude to be no less than secondary.
Swelling property halogen-free organic fireproof block material of the present invention have long-term flexibility, fire-resistant, oil-proofness good, under the thermal-flame effect, expand, and do not discharge the toxic fumes that irritating poisonous hydracid hydrogen and smog effectively stops the scene of a fire to produce and spread to contiguous diffusion by holes through walls such as electric wire, cables.Its technical indicator reaches: a, fire performance: 〉=180 minutes; B, density :≤2.0 * 10
3Kg/m
3C: water tolerance: 〉=3 days; D oil-proofness: 〉=3 days; E erosion resistance: 〉=7 days; F burning back hydrogen halide content: 0mg/g; G expansion character: 〉=150%; Wherein, index expansion character and the hydrogen halide content explanation of burning back: expand when expansion type halogen-free organic fireproofing blocking material is met fire, expansion character reaches 150%, overcome the problem that the meeting under the thermal-flame effect of existing organic fire prevention calking produces irritant gas and smog, also eliminated the toxic fumes that can not effectively stop the scene of a fire to produce simultaneously and spread the drawback that spreads to vicinity by holes through walls such as electric wire, cables.
