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

Abstract

The invention discloses a pretreatment filling liquid applied to artificial inorganic stone and its pretreatment method and application. The pretreatment filling liquid includes A component and B component, and the A component includes a mass percentage of 0.1-1% The silane coupling agent; the B component is composed of a variety of silica sol fillers with different particle sizes, specifically including silica sol with a particle size range of 135-85nm in a mass percentage of 1-3%, and a mass percentage of 4-85nm. 6% of silica sol with a particle size range of 60-80nm, and 5-8% by mass of silica sol with a particle size range of 8-30nm. The pretreatment filling solution of the present invention is compounded with various components, and the grinding and polishing process is improved at the same time, so that the artificial stone produced by it can achieve excellent results in ring white repair ability, antifouling ability 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
