Precipitated Silica Matting Agent For Industrial Coating

Silica has different uses in different products. As a good synthetic rubber supplement, its reinforcing performance is second only to carbon

black, and if it is ultra-fine and properly surface treated, it is even better than carbon black. In particular, white, colored and light-colored rubber

products are more suitable. As a thickener or thickener, synthetic oil, insulating coating regulator, paint fader, electronic component packaging

material thixotropic agent, fluorescent screen coating fluorescent powder precipitant, color printing plate filler, casting release agent. Added to

resin, it can improve the moisture resistance and insulation performance of the resin. Filled in plastic products, it can increase the anti-slip and

oil-proof properties. Filled in silicone resin, it can be made into plastics over 200°C. As a surface component of filling and paper in the papermaking

industry.

Precipitated silica is a material widely used in rubber reinforcement. Generally speaking, since the reinforcement effect of silica precipitation (except

ultra-fine and surface treatment) is not as good as carbon black, it belongs to semi-reinforced filling material. Therefore, the percentage of carbon black

replacement is determined according to the use occasion. Silica can be used as a filling material for plastics which can improve the elastic strength

and wear resistance of plastics, as well as the thermal stability of hardness. Cables can also improve the electrical insulation of cables, such as methyl

vinyl silicone rubber high-voltage lines using Fumed Silica or high-quality precipitated silica. It is usually not easy to separate the two layers of plastic film,

and the bag mouth is difficult to open, so silica is a very top-level opening agent. When polyvinyl chloride is used as a household floor material, if a certain

amount of silica is added, the hardness, elasticity, thermal denaturation and other properties of the product can be improved.

Silica, as an adhesive, can improve the whiteness and opacity of paper, and improve printing performance, oil resistance, wear resistance, feel and gloss.

Used for drying drawings, it can make the surface quality of paper good, the ink stable, and there is no crack on the back; used for superimposing nitrogen

paper, it can produce high-quality orchid drawings; used for coated paper, it can replace titanium dioxide; especially for newsprint, adding 1~2% of silica can

reduce the weight of paper by 10%, which can not only make the paper thinner, but also improve the strength of the paper. In addition to preventing ink

penetration and making printed text clear, it can also increase opacity.

Silicon dioxide has contact properties. Adding a small amount of silicon dioxide to the coating can eliminate the dripping precipitation of the coating. In the

unsaturated polyester coating, as long as a concentration of 0.5~2% of silicon dioxide is added, the coating will not have droplets and wrinkles when 500g/m2

is applied on the vertical surface each time. Adding silicon dioxide to the pigment can not only prevent the pigment from settling, but also improve the adsorption

and dispersibility of the pigment and dye. When used as a filler in emulsified coatings, it can improve thermal stability.
