Pretreatment filling liquid applied to artificial inorganic stone and pretreatment method and application thereof

Abstract

The invention discloses a pretreatment filling liquid applied to artificial inorganic stone and a pretreatment method and application thereof, the pretreatment filling liquid comprises a component A and a component B, and the component A comprises 0.1-1% by mass of a silane coupling agent; and the component B is composed of a plurality of silica sol fillers with different particle sizes, and specifically comprises the following components in percentage by mass: 1-3% of silica sol with the particle size range of 135-85 nm, 4-6% of silica sol with the particle size range of 60-80 nm and 5-8% of silica sol with the particle size range of 8-30 nm. According to the pretreatment filling liquid disclosed by the invention, all the components are compounded, and meanwhile, a grinding and polishing process is improved, so that the produced artificial stone can achieve excellent effects in the aspects of ring white repairing capability, antifouling capability and glossiness.

Description

technical field [0001] The invention relates to the field of inorganic stones, in particular to a pretreatment filling liquid applied to artificial inorganic stones, a pretreatment method and application thereof. Background technique [0002] At present, stone is a kind of building material used and in great demand in the field of architectural decoration. Natural stone (granite, marble) is naturally dignified and has good weather resistance, good stability and durability. It is widely used in outdoor floors, walls, cylinders, feet, bases and steps of buildings. Stone raw materials are easy to obtain, easy to form, and low in cost, and its application in the field of architectural decoration has attracted more and more attention. [0003] Artificial stone uses unsaturated polyester resin as a binder, together with inorganic powder such as natural marble or calcite, dolomite, silica sand, glass powder, and an appropriate amount of additives such as coloring materials. After ...

Problems solved by technology

This technology is usually applied to the surface treatment of high-precision ceramic tiles, and is rarely directly applied to the surface of stone, especially the surface of artificial stone. The reason is that ceramics are fired at high temperature and are resistant to high temperature. 1. Colored pigments are not resistant to high temperature. The grinding and polishing technology applied on ceramics is directly applied to artificial stone. After grinding and polishing, after being placed indoors for a certain number of days, some obvious ring-shaped and whitish marks will appear on the surface of the artificial stone. Not only reduces the durable quality of the product but also affects the appearance of the product
