Styrene-free artificial stone and preparation method thereof
The invention discloses a styrene-free artificial stone and a preparation method thereof. The preparation method comprises the following steps: uniformly stirring and mixing 8-9 parts by weight of artificial stone resin, 50-65 parts by weight of 20-40 mesh calcium carbonate aggregate, 25-40 parts by weight of 200-1500 mesh calcium carbonate filler, 0.4 part by weight of color paste, 1.5-2 parts byweight of silane coupling agent (KH570) and 0.5-2 parts by weight of initiator tert-butyl peroxy-2-ethylhexanoate in a high-speed mixer; The preparation method comprises the following steps: puttingthe raw materials into a high-speed mixer, uniformly stirring and mixing the raw materials, pavingthe raw materials into a mold frame, carrying out vibration compression molding under the vacuum condition of 0.1 Mpa for 3-5 minutes, heating and curing the mixture for 30-60 minutes under the condition of 85-110 DEG C, and grinding and polishing the mixture to obtain the product. The preparation method has the advantages that styrene which is widely applied to traditional artificial stone resin is not used as an active diluent, so that the problems of environmental pollution and health caused bystyrene are solved; the prepared styrene-free artificial stone resin has the advantages of higher flexibility, controllable cost, simple operation and adjustable comprehensive properties.
本发明公开了一种无苯乙烯人造石及其制备方法。该制备方法包括，以重量计算，将人造石树脂8～9份，20～40目的碳酸钙骨料50～65份，200～1500目的碳酸钙填料25～40份，色浆0.4份，硅烷偶联剂(KH570)1.5～2份，引发剂过氧化2‑乙基己酸叔丁酯0.5～2份，置于高速混合机搅拌混合均匀后，铺入模框内，在真空0.1Mpa条件下振动压制成型，压制时间为3～5min，再在85～110℃条件下加热固化30～60min，后打磨抛光即得产品。本发明的优点在于：不使用广泛用于传统人造石树脂中的苯乙烯为活性稀释剂，解决了其所带来的环境污染和健康问题；所制得的无苯乙烯人造石树脂具有较高的柔韧性，且成本可控、操作简单、综合性能可调。
