Embodiment

[0014] Embodiment: The preparation method of artificial quartz stone plate, the raw material of artificial quartz stone plate comprises quartz sand of 10-120 mesh, quartz powder of 150-400 mesh, and low-melting glass powder of 400-500 mesh, each raw material is by mass percentage: Quartz Sand is 60-75%, quartz powder is 13%-32%, and low-melting glass powder is 8%-13%. The preparation steps include: step 1, clean the quartz sand to form base sand; Powder and quartz powder are weighed by a metering device and then mixed with the two raw materials; step 3, the base sand in step 1 and the mixture in step 2 are each sent to the mixer at a ratio of 50% for sufficient centrifugal mixing; step 4. Send the mixture of step 3 to molding equipment for laying, shaping, vibration extrusion; step 5, heating; step 6, cooling and solidification; step 7, surface grinding and edge trimming to obtain the finished product.

[0015] The content of quartz sand in the plate is between 50% and 65%, an...

Abstract

The invention relates to a preparation method of a synthetic quartzite sheet material, which is characterized in that the synthetic quartzite sheet material comprises the following raw materials: 10-120 meshes of quartz sand, 150-400 meshes of quartz powder and 400-500 meshes of low melting glass powder; the sheet material comprise the following raw materials by mass percentage: 60-75% of quartz sand, 13-32% of quartz powder and 8-13% of low melting glass powder; the preparation method comprises the following steps: 1)cleaning the quartz sand to form base sand; 2)respectively weighing the low melting glass powder and quartz powder through a metering device and mixing two raw materials; 3)sending the base sand in the step 1) and a mixture in the step 2) according to 50% proportion in a mixing machine for fully centrifuging and mixing; 4)sending the mixture in the step 3) in moulding equipment for spreading materials, shaping, and vibrating and extruding; 5)heating; 6)cooling and solidifying; and 7)polishing surface and trimming to obtain the finished product. The preparation method has the beneficial effect that no chemical is added, technology is simple, and efficiency is high.

Description

technical field [0001] The invention relates to a preparation method of an artificial quartz stone plate. Background technique [0002] The existing resin-type artificial stone slab technology is to stir and mix the resin and quartz sand powder before forming the upper mold. After the resin is opened, the solvent begins to volatilize, and the resin will chemically react with the air. Therefore, when the mold is clothed, it will Limited by time, and due to the viscosity of the resin adhesive, it is difficult to disperse the material in the mold, and the distribution is uneven, causing the surface pattern of the plate and the density of each part of the plate to be uneven, and the stress is different due to the different density. out of shape. [0003] At present, all traditional artificial stone plates use unsaturated resin as adhesive, so accelerator, coupling agent and curing agent are required as chemical auxiliary materials, which have disadvantages: [0004] 1. Harmful...
