Problems solved by technology

In order to meet the needs of sound insulation and noise reduction, OEMs generally require the wet film thickness of water-based damping coatings to be about 2~4mm. During the opening time, due to the volatilization of water, the volume shrinks, and it is easy to appear on the premise of ensuring good thixotropy. cracking phenomenon
It is difficult to find products that meet this opening time in the market at present

Abstract

The invention provides a high-performance water-based damping coating, and relates to the field of chemical products and coating preparation, and the high-performance water-based damping coating comprises the following raw materials by weight: 20-40% of a water-based emulsion; 20-60% of an inorganic filler; 0.5-2% of a dispersant; 0.2-1% of a defoaming agent; 1-3% of functional powder; 0-10% of water; 0.6-2% of a rheological additive; and 0-20% of a flame retardant. According to the high-performance water-based damping coating provided by the invention, functional powder is introduced into a system, so that the anti-cracking capability of a wet film is greatly improved, the requirement of a main engine plant on the opening time is met, and meanwhile, the high-performance water-based damping coating has good adhesiveness, high strength, high flame retardance, excellent weather resistance and outstanding shock absorption and noise reduction effects.

Description

Technical field [0001] The present invention relates to the preparation of chemical products and coatings, and more particularly to a high performance aqueous damping coating. Background technique [0002] Sexual damping coatings are a high molecular material with a vibration and noise reduction function, which can be used in construction machinery, rail transit, aircraft, ship, cars and other fields. Compared to traditional damping materials (such as asphalt damping board), there is the following advantages: 1 Damping performance is excellent; 2 low density, light weight; 3 adopt robot spraying, improve automation; 4 low VOC, formaldehyde emissions. In summary, the aqueous damping coatings are increasingly focused on domestic and foreign mainframes, such as Yulai, Geely, BYD, Great Wall, etc. [0003] There are many water-based damping products in the market, such as foreign brands: Henkel, Ido, PPG, etc. With the difference in spraying process of different host plants, the requ...
