Abstract

The invention provides an anti-rust and weather-resistant brush-coating macromolecular material as well as a preparation method and the application thereof, and relates to the technical field of an anti-rust macromolecular material. The anti-rust and weather-resistant brush-coating macromolecular material comprises the following raw materials in parts by mass: 70 to 130 parts of 107 silicon rubber, 10 to 30 parts of a nano-silicon powder, 0.5 to 2 parts of a first silane coupling agent, 0.3 to 1.5 parts of a second silane coupling agent, 1 to 5 parts of ethyl silicate and 0.2 to 1 part of organic tin. The technical problems that the traditional brush-coating material has a low fireproof property, a weather resistance and waterproof property, has probability of peeling off, cracking and falling off, has short service life and high cost, is toxic and not environmentally-friendly, and is complex in construction process and difficult in construction are solved. The anti-rust and weather-resistant brush-coating macromolecular material provided by the invention has a high anti-rust property, a fireproof property, weather resistance and a waterproof property, has low probability of peeling, cracking and falling off under various severe environments, is long in service life, non-toxic, environmentally-friendly, low in cost and simple in manufacturing method, can perform brush-coating with rust, is easy to construct and has a good future application prospect.

Description

technical field [0001] The invention relates to the technical field of anti-rust materials, in particular to an anti-rust and weather-resistant brush-coated polymer material and a preparation method and application thereof. Background technique [0002] Power equipment operates in natural environments such as wind, frost, rain, snow, high temperature, severe cold and chemical corrosion for a long time. Under the influence of external factors, the performance of power equipment will deteriorate, metal corrosion and rainwater leakage will seriously threaten the safety of power equipment run. The existing commonly used outdoor antirust materials for power equipment are all paints, but they have the following defects: they have a strong pungent smell, are toxic and not environmentally friendly, and are harmful to the human body during construction; It is easy to cause fatal hazards in the event of a fire; the paint construction is complicated, and the primer is required, and th...
