Embodiment 1～3

[0037] Embodiment 1~3 prepares the high solid content coating of anti-radiation anti-corrosion bottom surface integrated

[0038] The specific method is as follows:

[0039] (1) Preparation of Component A

[0040] ① Prepare each component according to the following ratio

[0041]Component A is composed of the following raw materials in terms of mass fraction: bisphenol A epoxy resin 12-18%, novolak epoxy resin 4-8%, dimer acid modified epoxy resin 4-8%, trihydroxy Methylpropane triglycidyl ether 5-10%, coloring pigment 2-10%, anti-corrosion pigment 15-25%, filler 15-25%, flame retardant 10-20%, defoamer 0.3-0.8%, flow The leveling agent is 0.3-0.8%, the diluent is 5-10%, the sum of the mass fractions of the above components is 100%, and the specific formula is shown in Table 1.

Abstract

The invention relates to a radioresistant and anticorrosive primer-topcoat high-solid coating and a preparation method thereof. The radioresistant and anticorrosive primer-topcoat high-solid coating comprises a component A and a component B, wherein the component A consists of the following components in percentage by mass: 12-18% of bisphenol A epoxy resin, 4-8% of novolac epoxy resin, 4-8% of dimeric dibasic acid modified epoxy resin, 5-10% of trimethylolpropane triglycidyl ether, 2-10% of a coloring pigment, 15-25% of an anticorrosive pigment, 15-25% of a filler, 10-20% of a flame retardant, 0.3-0.8% of a defoaming agent, 0.3-0.8% of a leveling agent and 5-10% of a diluting agent; the component B consists of the following components in percentage by mass: 55-65% of a modified polyamide curing agent and 35-45% of a modified aromatic amine curing agent; before construction, the component A and the component B are uniformly mixed together according to a mass ratio of 3-4:1. The radioresistant and anticorrosive primer-topcoat high-solid coating has excellent radiation protection performance and strong decontaminating capability, passes through an analog DBA (design basis accident) test, has excellent corrosion resistance and is low in VOC (volatile organic compound) content.

Description

technical field [0001] The invention relates to a radiation-resistant and anti-corrosion bottom-surface-integrated high-solid coating and a preparation method thereof. Background technique [0002] Nuclear power is a high-quality and efficient clean energy with mature technology, good economy and strong continuous supply capacity. Accelerating the development of clean energy and renewable energy is conducive to building a stable, economical, clean, and safe energy supply system, and is also conducive to protecting the ecological environment and improving people's quality of life. The third-generation advanced passive pressurized water reactor nuclear power technology developed by the United States, that is, the AP1000 nuclear power technology is the crystallization of 50 years of experience and wisdom in the development of nuclear power in the world. Since the design of this passive pressurized water reactor nuclear power plant is very different from the previous nuclear po...
