preparation example Construction

[0038] The mixed solvent is composed of environment-friendly aromatic hydrocarbon solvent oil and propylene glycol methyl ether acetate. The weight ratio of aromatic hydrocarbon solvent oil and propylene glycol methyl ether acetate is 2:1. Both aromatic hydrocarbon solvent oil and propylene glycol methyl ether acetate It is a product of Yangzhou Hualun Co., Ltd., and the aromatic hydrocarbon solvent oil is specifically selected from S-100A. In particular, it should be noted that during the preparation of the nano-enamel, the mixed solvent is added step by step. The preparation method of the nano-enamel varnish of the present invention comprises the steps of pre-treatment of nano-materials, dispersing of millbase, let-down of paint and the like. During the pretreatment process of the nanometer material, the added amount of the mixed solvent is 2-4 parts. In the step of dispersing and grinding the millbase, the added amount of the mixed solvent is 5-7 parts. In the paint let-d...

Abstract

The invention discloses nanometer enamel used for aircraft skin and a preparing method thereof, and belongs to the technical field of paint, mainly solving the technical problems that enamel at present has unsatisfactory ultraviolet radiation aging resistance and thermal ageing resistance and cannot meet requirements of long-term flight of aircrafts. The nanometer enamel comprises following components by weight: 3-5 parts of modified polyester resin, 30-35 parts of acrylic resin, 20-25 parts of titanium dioxide, 3-4 parts of nanometer silicon dioxide, 3-6 parts of a dispersant, 0.5-1 part of a silane coupling agent, 8-10 parts of precipitated barium sulphate, 10-15 parts of a curing agent, 15-36 parts of a mixed solvent, 0.2-0.3 part of a leveling agent, 0.2-0.3 part of a defoaming agent and 0.1-0.3 part of a catalyst. The preparing method includes steps of nanometer material pretreatment, mill base dispersion, paint mixing, filtration, and the like. The nanometer enamel has excellent ultraviolet radiation aging resistance and thermal ageing resistance at the same time of meeting common performance requirements, and can meet requirements of long-term flight of aircrafts.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a nano-enamel paint, in particular to a nano-enamel paint used for aircraft skin surfaces and a preparation method thereof. Background technique [0002] Coatings and coating systems composed of coatings are an important class of functional materials used in large quantities on aircraft skins. In view of the complexity and variability of the aircraft flight environment, in addition to requiring the use of aircraft skin surface coatings to be resistant to ultraviolet rays, rain erosion, aging, aging, high and low temperature, etc., it is also required to have anti-fog and heat resistance. , oil resistance, the function of absorbing and radiating certain electromagnetic waves. The coating used by the aircraft must also be able to resist the erosion of various liquids used by the aircraft itself, such as anti-lubricating oil, hydraulic oil, jet fuel, etc. It can be seen that the pr...
