Mineral composite material and preparation process thereof
The invention discloses a mineral composite material and a preparation process thereof. The mineral composite material comprises a base material, aggregate, filler, a reinforcing material, a curing agent and a toughening agent, the base material is modified phenolic resin, and a preparation method of the modified phenolic resin comprises the following steps: carrying out wet blending modification on submicron barite, phenolic resin and nano silicon dioxide in a high-speed stirring ball mill; the preparation method has the beneficial effects that the modified phenolic resin is adopted as a base material, and the phenolic resin is compounded on the surface of the modified phenolic resin due to small particle size, large specific surface area, many surface non-paired atoms and high surface chemical activity of nano-submicron minerals, so that the modified phenolic resin has strong bonding capacity with the phenolic resin and can generate a special effect on the physical and chemical properties of the phenolic resin; thermal decomposition of organic matters can be inhibited, the thermal decomposition temperature of the phenolic resin is increased, the heat resistance of the nano-modified phenolic resin is obviously superior to that of common phenolic resin, and the thermal deformation resistance of the mineral composite material is improved.
本发明公开了一种矿物复合材料以及制备工艺，包括基体材料、骨料、填料、增强材料、固化剂、增韧剂；所述基体材料为改性酚醛树脂，所述改性酚醛树脂制备方法如下：将亚微米重晶石、酚醛树脂、纳米二氧化硅在高速搅拌球磨机中进行湿法共混改性；本发明的有益效果是：基体材料采用改性酚醛树脂，由于纳米‑亚微米矿物粒度小、比表面积大、表面非配对原子多、表面化学活性高，在其表面复合酚醛树脂，因而与酚醛树脂结合能力强，并可对酚醛树脂的物化性能产生特殊作用，可抑制有机物的热分解,提高酚醛树脂的热分解温度，纳米改性酚醛树脂的耐热性明显优于普通酚醛树脂，增加了矿物复合材料的耐热变形性能。
