Preparation method of composite stone plate and composite stone plate
The invention discloses a preparation method of a composite stone plate. The preparation method includes the steps that raw materials are mixed to obtain a first mixture and a second mixture; the first mixture or the second mixture is distributed into a mold; a loose first layer is formed; the first layer is pre-pressed, and the other mixture is distributed to obtain a green body; and then vibrating and thermal curing are carried out to obtain a finished product of the composite stone plate, wherein the first mixture does not contain calcium carbonate, and the second mixture contains calcium carbonate. The preparation method adopts a double-layer material distribution method to form the composite stone plate with a layered structure, wherein calcium carbonate is not added into a formula ofa top layer, so that the top layer is high in hardness, and the acid and alkali resistance and stain resistance are excellent; and calcium carbonate is added in a bottom layer, the use amount of resin can be effectively reduced, and the cost of raw materials is reduced.
本发明公开了一种复合石板的制备方法，其包括，将原料混合，得到第一混合料和第二混合料；第一混合料或第二混合料布料至模具之中；形成松散的第一层；预压第一层进行预压，并布料另一混合料，得到坯体；进而振压、热固化，得到复合石板成品；其中，所述第一混合料中不包括碳酸钙，所述第二混合料中包括碳酸钙。本发明采用双层布料的方法，形成了具有分层结构的复合石板；其中，顶层的配方之中不加入碳酸钙，使得顶层硬度高，耐酸碱性、耐污性优良；底层之中加入碳酸钙，可有效减少树脂的用量，降低了原料成本。
