Solvent-free type corrosion inhibiting, vibration damping, and noise reducing coating material and preparation method thereof

Abstract

The invention relates to a solvent-free type corrosion inhibiting, vibration damping, and noise reducing coating material and a preparation method thereof, and belongs to the technical field of chemical materials. The coating material comprises two components: a component (A) and a component (B). The component (A) is composed of long-side-chain hydroxyl acrylic resin, epoxy resin, a thixotropic agent, a dispersing aid, an antifoaming agent, a damping filler, a heavy sound insulation filler, a fire retardant, and color paste. The component (B) is an isocyanate curing agent. Adopted long-side-chain hydroxyl acrylic resin and epoxy resin are compounded to form IPN type polymer, which can effectively enhance the properties of the coating material such as damping performance, fire retardant performance, adhesion force, and the like; the shortage that a conventional damping paint only has one single function is overcome; at the same time, the coating material contains the damping filler, thedamping performance is improved, at the same time, the compactness of the coating is further strengthened, the anticorrosion performance of the coating is enhanced; and moreover, the coating materialdoes not contain any organic solvent or water, barely pollutes the environment, can be rapidly cured at a room temperature, and is convenient for construction.

Description

technical field [0001] The invention specifically relates to a solvent-free coating material with anti-corrosion, vibration-reduction and noise-reduction functions and a preparation method thereof, belonging to the technical field of chemical materials. Background technique [0002] The International Maritime Organization (IMO) has passed a resolution requiring that ship structures should comply with the "Noise Level Regulations on Ships" reviewed and approved to protect personnel from noise damage. In fact, ships have been floating on the sea for a long time, and there are many noise sources. If the noise cannot be effectively controlled, it will cause certain damage to the structure of the hull. In the shipbuilding industry, the traditional method of reducing vibration and noise is to strengthen the hull structure, which does not consume the vibration energy fundamentally, but only spreads it to other parts. At present, vibration and noise reduction technologies commonly ...

Problems solved by technology

[0004] Aiming at the problems of existing damping coating products such as large environmental pollution, poor construction performance, and single function, the purpose of the present invention is to provide a solvent-free anti-corrosion, vibration, noise and noise reduction coating material and its preparation method. The IPN type polymer formed by compounding the long side chain hydroxyl acrylic resin and epoxy resin can effectively improve the damping, flame retardancy, adhesion and other properties of the coating material, and overcome the shortcomings of the existing damping coatings with single performance; at the same time, the coating The damping filler added in the layer material can further enhance the compactness of the coating and improve the corrosion resistance of the coating while improving the damping performance; and the coating material does not add organic solvents or water, which has little environmental pollution and can be used at room temperature It can achieve fast curing under low pressure and good construction performance
