High-strength anti-cracking epoxy ground stone plate material
The invention relates to the technical field of epoxy grindstone materials, and discloses a high-strength anti-cracking epoxy grindstone plate material which comprises the following components: modified epoxy resin, multi-stage aggregate, a curing agent and basalt fibers, wherein the multi-stage aggregate is formed by mixing at least two different types of aggregates with different particle size grades; wherein the modified epoxy resin is prepared by taking glycidyl ether epoxy resin as a raw material; wherein diphenol propane type epoxy resin is adopted as the glycidyl ether epoxy resin; epoxy resin is modified, reaction can be started at a low temperature under the action of the curing agent 4, 4 '-diaminodiphenyl sulfone, meanwhile, released heat initiates reaction of low-activity aromatic amine, the overall reaction rate is greatly increased, and therefore the curing efficiency of the epoxy ground stone plate material is improved, and the curing time is shortened.
本发明涉及环氧磨石材料技术领域，且公开了一种高强抗裂的环氧磨石板材料，包括以下成分：改性环氧树脂、多级骨料、固化剂、玄武岩纤维；其中，所述多级骨料由不低于两种的不同种类不同粒度等级的骨料混合而成；其中，所述改性环氧树脂以缩水甘油醚类环氧树脂为原料进行制成；其中，所述缩水甘油醚类环氧树脂采用二酚基丙烷型环氧树脂；本发明通过对环氧树脂进行了改性，并在固化剂4,4’‑二氨基二苯砜的作用下，能够在较低温度下开始反应，同时放出的热量引发低活性芳香胺反应，使整体反应速率大幅度加快，从而提高环氧磨石板材料的固化效率，缩短固化时间。
