Problems solved by technology

However, the quartz stone products made by the above three methods have serious homogeneity and a single pattern. Generally, they can only form irregular pattern patterns such as dots and blocks, and cannot form many different types of pattern patterns well. Especially linear patterns
The products produced by it are not very

Example Embodiment

[0048] Therefore, the present invention provides a method for preparing quartz stone, which can form various types of patterns, especially linear patterns, on the surface of quartz stone without using a mold, so as to improve the competitiveness of products.

[0049] see figure 1 , the invention provides a kind of quartz stone preparation method, including:

[0050] S101. Weigh the main raw materials required for preparing the quartz stone, and stir the main raw materials evenly.

[0051] The formula of the main raw materials required for the preparation of quartz stone is as follows (in weight percent):

[0052] Aggregate 85-95%

[0053] Resin 5-15%;

[0054] The aggregate includes quartz sand and quartz powder;

[0055] The resin is an unsaturated polyester resin.

[0056] Preferably, the formulation of the main raw materials required for the preparation of quartz stone is as follows (in weight percent):

[0057] Aggregate 88-92%

[0058] Resin 8-12%.

[0059] More p...

Example Embodiment

[0098] Example 1

[0099] A. Stir the mixture: add 90% of quartz sand and quartz powder and stir for 2 minutes, then add 0.05% of silane coupling agent KH-570 and 0.05% of OT curing agent, 0.4% of colorant and 9.5% of unsaturated polyester The resin was stirred for 2 minutes, poured into the mixer and stirred with quartz sand and quartz powder for 5 minutes after stirring, and the curing temperature was set to 90 ° C, wherein the color material included three color materials A, B, and C, and material A was yellow (mainly Color), material B is white, material C is gray, and three color materials A, B, and C are mixed well with their respective mixers;

[0100] B. Flatten the raw materials through the cloth machine to realize the first cloth. In the first cloth process, add the three color materials A, B, and C in turn and cloth, that is, first cloth A material, then cloth B material, and finally Cloth C material;

[0101] C, carry out the first compression molding by the pres...

Abstract

The invention discloses a preparation method of quartz stone. The method comprises the following steps of: A, weighing and uniformly stirring main raw materials required for preparing the quartz stone; B, primarily distributing the main raw materials; C, performing first compression moulding on the primarily distributed main raw materials through a press to obtain a blank; D, cutting the blank to required figures through a cutting device to obtain a semi-product; E, secondarily distributing the semi-product; F, performing second compression moulding on the secondarily distributed semi-product through the press; G, drying and moulding the secondarily pressed semi-product; and H, polishing the dried and moulded semi-product to obtain a finished product. Correspondingly, the invention further discloses the quartz stone prepared by the preparation method. Due to the adoption of the preparation method disclosed by the invention, under the premise of no dies, figures of various types, especially linear figure patterns can be formed on the surface of the quartz stone, so that the competitiveness of the product is improved.

Description

technical field [0001] The invention relates to the technical field of artificial quartz stone, in particular to a quartz stone and a preparation method thereof. Background technique [0002] Artificial quartz stone has the advantages of low shrinkage, low manufacturing cost, easy processing, rich color, outstanding product performance, high hardness, etc. It has been made into various industrial and civil floors and decorative materials, and is widely used in industrial production and people In daily life, it is used as a decorative material for floor tiles and walls. [0003] So far, the preparation process of artificial quartz stone is: stirring→cloth→pressing→drying and molding→polishing→inspecting and entering the warehouse. Among them, the molding methods of the artificial quartz stone pattern are roughly divided into three categories: the first category is to directly sprinkle quartz powder and toner on the quartz stone plate. The second type sprays color paste dire...
