Abstract
The invention relates to an anti-shock-deformation fireproof door core. A preparation method comprises the following steps: mixing 30-40 parts of polyvinyl alcohol and 100-140 parts of water to preparing glue; putting the glue into a high-speed shearing machine, adding 5-10 parts of pored expanded perlite, 3-6 parts of magnesium aluminum silicate, 3-5 parts of an ethylene-vinyl acetate copolymer, 3-5 parts of an organic silicon flatting agent, 70-95 parts of sulphate aluminum cement and 2-3 parts of an amino alcohol corrosion inhibitor, and performing high-speed shearing and stirring, wherein the shearing speed is 6000-8000 RPM and the shearing time is 5-10min; transferring a product obtained from the former step into a high-speed stirring machine and adding 0.5-2 parts of the high-alumina cement foaming agent, wherein the stirring rotating speed is 1000-1500r/min and the stirring time is 10-15min; lastly, adding 20-30 parts of PVA short filaments and stirring, wherein the stirring rotating speed is 800-1000r/min and the stirring time is 5-10min; discharging the materials into a mould; regularly stacking for a 10dm<3> wire basket in the mould; and standing by in the mould till curing and forming, and then taking out and drying till the water content is 12%.
Description
Technical field
The present invention relates to a kind of shock resistance distortion 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, shock resistance distortion fire-resistant door core that acoustic insulation shock-proof, stable performance, use safety, life-span are long and preparation method thereof.
The technical solution used in the present invention is: a kind of shock resistance distortion fire-resistant door core, is characterized in that: comprise by mass fraction: polyvinyl alcohol 30-40 part, aluminosulfate cement 70-95 part, perforate pearlstone 5-10 part, neusilin 3-6 part, amine alcohols rust inhibitor 2-3 part, ethylene-vinyl acetate copolymer 3-5 part, organosilicon flow agent 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 shock resistance distortion 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 perforate pearlstone 5-10 part, neusilin 3-6 part, ethylene-vinyl acetate copolymer 3-5 part, organosilicon flow agent 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 that waste of material is few, metering accurately, the advantage that bubbling efficiency is high, foaming is stable, effective, in conjunction with the short silk of PVA and wire basket, stablize foaming structure and bulk strength, and further raising working strength and shock resistance are out of shape.
