Abstract

The invention discloses an oily exterior wall paint, which comprises the following components in percentage by weight: 35 to 60 percent of thermoplastic acrylic resin, 20 to 30 percent of titanium white, 15 to 30 percent of ferrotitanium powder, 10 percent of refined barium sulfate, 1 to 5 percent of nanosilica or hydrated magnesium silicate, 0.8 to 2 percent of organosilane or high white aluminium silicate, 0.1 to 0.3 percent of titanate coupling agent and 0.1 to 0.5 percent of organic silicon leveling agent, and is produced by the conventional process. The product is mainly used as an interior and exterior paint of various buildings, and particularly has long protection period and decoration effect on exterior walls in areas with serious acid rain and humid climate.

Description

technical field [0001] The invention relates to a paint, in particular to a paint mainly used for anti-corrosion and acid-resistance on the outer wall of a building, and belongs to the technical field of chemical products. Background technique [0002] In Southwest China, acid rain is heavy and the climate is humid. Acid rain has seriously affected and damaged the earth's ecological environment and human society and economy. It not only causes great economic loss, but also endangers building safety. Studies have shown that acid rain has a strong corrosive effect on building materials such as metals, stones, cement, and wood, thus seriously damaging buildings. In acid rain areas, damage caused by acid rain abounds, and many buildings are severely damaged by acid rain corrosion. Although the current common exterior wall paint has a certain protective and decorative effect, due to acid rain erosion, the paint film will soon lose light (up to three years), chalking, cracking, ...
