Abstract
The invention relates to the field of organosilicon coatings, and discloses an organosilicon paint with weather resistance, salt spray resistance and convenient construction. ~80 parts, 0.1-5 parts of pigment, 10-20 parts of crosslinking agent, 0.1-2 parts of catalyst, 0.1-5 parts of coupling agent, 15-35 parts of solvent, pretreatment of reinforcing filler before use, pretreatment method It is: after the basic silicone polymer and the coupling agent are stirred, the reinforcing fillers that are pre-dehydrated and dried are added and mixed. The coating of the present invention achieves good bonding effect on common substrates such as metal, cement, glass, etc., and has good weather resistance, salt spray resistance and ultraviolet resistance, and is especially suitable for offshore facilities and the like. Use in UV environments. The construction method can be directly sprayed, and the anti-sagging performance is good. The thickness of single-pass coating can reach 200μm, which can effectively reduce the number of coating times and simplify the process flow.
Description
technical field [0001] The invention relates to the field of organosilicon coatings, in particular to an organosilicon coating with weather resistance and salt spray resistance and convenient construction. Background technique [0002] Organosilicon, namely an organosilicon compound, refers to a compound containing a Si-O bond and at least one organic group directly connected to a silicon atom. Due to the unique structure of silicone, it combines the properties of inorganic materials and organic materials. It has the basic properties of low surface tension, small viscosity-temperature coefficient, high compressibility, high gas permeability, and has high and low temperature resistance, electrical insulation, oxidation resistance and stability. It is widely used in aerospace, electrical and electronic, construction, transportation, chemical industry, textile, food, light industry, medical and other industries. Among them, silicone is mainly used in sealing, bonding, lubricat...
