Organosilicon special coating

Abstract

The invention discloses an organosilicon special coating. The organosilicon special coating comprises the following components in parts by weight: 30-60% of aluminum oxide, 20-30% of Stoddard solvent, 5-20% of petroleum distillate, 0.5-2% of vulcanized silicone elastomer, 5-10% of methyltrisilane, 5-10% of metallic aluminum and 0.5-5% of metallic silver. By adopting the technical scheme provided by the invention, the metal particles can be uniformly distributed on the physical structure surface stabilized by the room temperature-vulcanized silicone elastomer; and no drift phenomenon of the metal particles occurs after a film is formed on the wall. Hence, the product has better electromagnetic shielding and anti-static functions. The coating prepared by using the technical scheme provided by the invention has good wear resistance performance and is convenient for cleaning contaminants. The contents of soluble volatiles, free formaldehyde and soluble lead and the like in the coating are far below the national standard GB18582-2001. The coating is very environmental-friendly and can be used in families.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a special silicone coating. Background technique [0002] With the country's emphasis on environmental protection and the improvement of public awareness of environmental protection, environmental disputes caused by electromagnetic radiation pollution have become one of the important issues affecting the construction of a harmonious society. Research and development and production of building interior and exterior wall coatings with electromagnetic shielding, environmental protection, simplicity, ease of use, and high cost performance have become the goals of relevant enterprises and technicians. The architectural electromagnetic shielding coatings in the prior art generally have anti-static functions. One type is made of composite materials such as barite and ferrite that absorb X-rays or electromagnetic waves, and the other type is to add conductive materials to the coating. It is made...

AI Technical Summary

Problems solved by technology

The common disadvantage of these two types is that the stability of the resin structure is poor, which leads to poor uniform distribution of metal particles, which affects its shielding and conductive effects; Adding ordinary topcoat on top will affect the effect of shielding and conductivity; third, it generally does not have the functions of waterproof, moisture-proof, and mildew-proof, and is not suitable for exterior wall construction; fourth, the surface-drying time is generally more than 6 hours, which affects the construction progress
