Artificial agglomerated stone imitating natural cracks and production process thereof
The invention discloses artificial agglomerated stone imitating natural cracks. The artificial agglomerated stone comprises the following raw materials: calcium carbonate coarse sand, superfine calcium carbonate powder, unsaturated polyester resin, toner, titanium dioxide, methyl ethyl ketone peroxide, cobalt iso-octoate, a coupling agent, styrene, octadecanoic acid, sodium phenylpropionate and glycerol. Octadecanoic acid and sodium benzoate generate composite acid modification, and glycerol and styrene are added according to a ratio, so that the unsaturated acid content in the unsaturated polyester resin is reduced, the impact resistance of the unsaturated polyester resin is improved, the cracking condition of the artificial stone in the production process is reduced, and the defective rate of the artificial stone product is reduced; the base material is spread into the mold paved with the auxiliary material through the material distributing machine, and the auxiliary material and the base material in the mold can be molded into an artificial stone blank with imitated natural cracks through the artificial stone vibration molding machine in a vibration pressing manner, so that different crack patterns are presented on the artificial stone blank, and the appearance diversification of the artificial stone is improved.
本发明公开一种仿天然裂纹人造岗石,其中原料包括:碳酸钙粗砂、超细碳酸钙粉、不饱和聚酯树脂、色粉、钛白粉、过氧化甲乙酮、异辛酸钴、偶联剂、苯乙烯、十八烷酸、苯丙酸钠和丙三醇;通过十八烷酸与苯甲酸钠产生复合酸改性,再搭配丙三醇和苯乙烯按比率投入,降低不饱和聚酯树脂中的不饱和酸含量,提高不饱和聚酯树脂的抗冲击性能,降低人造石在生产过程中出现开裂的情况,降低人造石产品的次品率,再通过布料机能把基料撒至铺有辅料的模具中,并通过人造石振动成型机能使得模具内的辅料和基料振压成型为带有仿天然裂纹的人造石毛坯,使得人造石毛坯上呈现不同的裂纹图案,提高了人造石的外观多样化。
