Artificial stone and preparation method thereof
The invention belongs to the technical field of artificial stones, and particularly discloses an artificial stone and a preparation method thereof. The artificial stone is prepared from the following raw material components in parts by weight: 35 to 50 parts of aggregate, 40.5 to 63 parts of an alkali efflorescence resisting agent, 5 to 15 parts of unsaturated polyester resin and 0.3 to 0.8 part of a curing agent, the alkali efflorescence resisting agent comprises pumice powder and white carbon black. The artificial stone with alkali efflorescence resistance is prepared by taking the pumice powder and the white carbon black as the alkali efflorescence resistance agents. Wherein the pumice stone has good moisture absorption and desorption performance, the unique mesoporous structure of the pumice stone can lock water vapor in the pore structure, the water vapor does not react with silicate substances in the stone, when the environment humidity is low, the water vapor is released through the desorption effect, and the water vapor cannot be gathered on the surface of the material, so that the pumice stone has good saltpetering resistance. The porous structure of the white carbon black also has certain moisture absorption and desorption performance for water vapor in the air, and the white carbon black can act together with the pumice stone to inhibit the saltpetering phenomenon on the surface of the artificial stone.
本发明属于人造石技术领域，具体公开了一种人造石及其制备方法。人造石，的原料组分按重量份计包括：骨料35‑50份，抗泛碱剂40.5‑63份，不饱和聚酯树脂5‑15份，固化剂0.3‑0.8份；抗泛碱剂包括浮石粉和白炭黑。本发明以浮石粉和白炭黑为抗泛碱剂，制备了具有抗泛碱性的人造石。其中：浮石具有良好的吸放湿性能，其独特的介孔结构能够将水汽锁定在孔洞结构中，不与石材中的硅酸盐类物质发生反应，当环境湿度低时又通过脱附作用释放出水汽，水汽不会聚集在材料表面，从而具备了良好的抗泛碱性能。白炭黑的多孔结构，对于空气中的水汽同样具有一定的吸放湿性能，可与浮石共同作用，抑制人造石表面的泛碱现象。
