Abstract
The invention relates to an elastic heat insulation fireproof door core. The elastic heat insulation fireproof door core comprises, by mass, 30-40 parts of polyving akohol, 70-95 parts of sulphate aluminium cement, 2-3 parts of an alkamine corrosion inhibitor, 3-5 parts of phenolic resin, 20-30 parts of PVA short filaments, 0.5-2 parts of an aluminous cement foaming agent and 100-140 parts of water. The preparation method comprises mixing 30-40 parts of polyvinyl alcohol and 100-140 parts of water to obtain glue, adding the glue into a high speed shearing machine, adding 3-5 parts of phenolic resin, 70-95 parts of the sulphate aluminium cement and 2-3 parts of the alkamine corrosion inhibitor into the high speed shearing machine, carrying out high speed shearing stirring at a shearing rate of 6000-8000r/min for 5-10min, transferring the mixture into a high speed stirring machine, adding 0.5-2 parts of the aluminous cement foaming agent into the mixture, carrying out stirring at a stirring rotation rate of 1000-1500r/min for 10-15min, adding 20-30 parts of the PVA short filaments into the mixture, carrying out stirring at a stirring rotation rate of 800-1000r/min for 5-10min, discharging the product into a mold, wherein the mold is filled with 10dm<3> steel wire cages stacked uprightly and foursquare, carrying out standing curing molding in the mold, taking out the product and carrying out drying until water content is 12%.
Description
Technical field
The present invention relates to a kind of Elastic heat insulation fire-resistant door core and preparation method thereof.
Background technology
Traditional halogen foaming doors core fire resistance is poor, fire of easily leaping up, returns halogen, the easy carbonization of high temperature, distortion, and can discharge obnoxious flavour in high-temperature heating process, has a strong impact on its work-ing life, safety performance and stability.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of lightweight, high-strength, excellent fire retarding performance, high-temperature heating without obnoxious flavour, Elastic heat insulation fire-resistant door core that stable performance, use safety, life-span are long and preparation method thereof.
The technical solution used in the present invention is: a kind of Elastic heat insulation fire-resistant door core, is characterized in that: comprise by mass fraction: polyvinyl alcohol 30-40 part, aluminosulfate cement 70-95 part, amine alcohols rust inhibitor 2-3 part, resol 3-5 part, PVA short silk 20-30 part, high-alumina cement whipping agent 0.5-2 part, water 100-140 part.
A kind of Elastic heat insulation fire-resistant door core preparation method, it is characterized in that: first polyvinyl alcohol 30-40 part and water 100-140 part are mixed and made into glue, glue is placed in high-speed shearing machine and adds resol 3-5 part, aluminosulfate cement 70-95 part and amine alcohols rust inhibitor 2-3 part high shear agitation, velocity of shear 6000-8000RPM, shear time 5-10min, be transferred to homogenizer, add high-alumina cement whipping agent 0.5-2 part, mixing speed 1000-1500r/min, churning time 10-15min, finally add the stirring of PVA short silk 20-30 part, mixing speed 800-1000r/min, churning time 5-10min, discharging is in mould, the full 10dm of upright accumulation in mould
3wire basket, quiet to curing molding in mould, take out and dry to water ratio 12%.
The existing halogen fire door of customer service of the present invention fill core fire resistance poor, easily leap up fire, return halogen, the easy carbonization of high temperature, distortion, the essence shortcoming of obnoxious flavour can be discharged in high-temperature heating process, there is high-strength light, excellent fire retarding performance, produce without harmful in high-temperature heating process, intensity stabilization, unit weight reaches 340-380kg/m
3, not efflorescence, meets GB8624-2006A1 level and does not fire standard, and GB/T20285-2006AQ1 " classification of material producing smoke toxicity risk ", and performance is obviously better than halogen foamed fireproofing door core material.And preparation technology of the present invention has, and waste of material is few, metering is accurate, the advantage that bubbling efficiency is high, foaming is stable, effective, in conjunction with the short silk of PVA and wire basket, stablizes foaming structure and bulk strength, improve elastic performance further in conjunction with resol, meet and variously install and use occasion.
