Preparation method of nano mesoporous functional mineral composite heat insulating and heat preserving core material
The invention discloses a nano mesoporous functional mineral composite heat insulating and heat preserving core material. The core material is prepared by the following method: 1) preparing a polymer organic material; 2) polymer organic material film coating: taking phenolic resin, nano-zinc oxide and nano-silicon oxide, and uniformly mixing them to synthesize a flame-retardant binder; putting EPP foamed particles into a mold box, uniformly stirring, adding the flame-retardant binder, and uniformly mixing; 3) preparing inorganic powder mineral slurry: adding powder minerals into a reaction kettle, fully and uniformly stirring in the reaction kettle and adding water to form the thick inorganic powder mineral slurry; (4) mixing and stirring: mixing the foamed particles coated with the film in the step (2) with the inorganic powder mineral slurry, injecting the mixture into a mixing box, adding nano mesoporous minerals, and stirring; and (5) curing and shaping: pressurizing and curing the mixture obtained in the step (4) at normal temperature, demolding to form blocks, and cooling. The heat value of the prepared heat preserving core material is less than 20, the K value is less than or equal to 0.040 w/m.k, the oxygen index is more than 30, and the hydrophobic rate is more than 99%.
本发明公开了一种纳米介孔功能矿物复合绝热保温芯材，它由下述方法制备：1）高分子有机材料制备；2）高分子有机材料覆膜：取酚醛树脂、纳米氧化锌、纳米氧化硅，混匀合成阻燃粘结剂；与份EPP发泡颗粒放入模箱中均匀搅拌，加入阻燃粘结剂，混合均匀；3）无机粉体矿物浆料制备：将粉体矿物加入反应釜，在反应釜中充分均匀搅拌加水，形成稠状的无机粉体矿物浆料；4）混料搅拌：将步骤2）覆膜后的发泡颗粒与无机粉体矿物浆料混合，注入混料箱，加入纳米介孔矿物搅拌5）熟化定型：步骤4）得到的混合料，于常温下加压，熟化；脱模形成块状，冷却；制备的保温芯材热值＜20，K值≤0.040w/m.k，氧指数＞30，憎水率99%以上。
