Sprayable baking type water soluble damping coating and preparation method thereof

Abstract

The invention relates to the field of damping materials, in particular to a sprayable baking type water soluble damping coating and a preparation method thereof. The sprayable baking type water soluble damping coating is prepared from, by weight, 10-50 parts of acrylic emulsion, 5-20 parts of emulgator, 0.1-10 parts of neutralizer, 1-20 parts of a dispersing agent, 1-15 parts of cosolvent, 10-80 parts of pigment filler and 1-50 parts of water. By means of a high-pressure spraying means, the thickness of a coating layer is fixed to be about 0.5-5 mm, sagging does not exist, after baking at the high temperature of 100-200 DEG C, curing can be achieved quickly, bubbling and disengaging do not occur, and the functions of vibration and noise reduction can be enhanced; water serves as a main solvent, so that the coating does not contain benzene volatile matter and does not seriously hurt the human health, and adopted equipment and tools can be washed through water; the needed raw materials are easy to get, the production process is simple, construction is convenient, operation is easy, the added value of products is high, the domestic blank is filled, and the coating can be greatly applied to the industries of automobiles, locomotives and the like.

Description

technical field

[0001] The invention relates to the field of damping materials, in particular to a sprayable and bakeable water-based damping paint and a preparation method thereof. Background technique

[0002] Polymer damping material is a functional material that uses a polymer as a matrix to suppress vibration and reduce noise. Construction machinery, precision instruments and equipment have been widely used. According to the dispersion medium, damping coatings can be divided into solvent-based damping coatings and water-based damping coatings. The damping coatings used in the early stage are all solvent-based damping coatings, mainly coal tar-asphalt damping coatings, solvent-based polyurethane damping coatings, etc. With the requirements of national industrial policies and the improvement of people's awareness of environmental protection, solvent-based damping coatings containing a large amount of organic solvents are gradually replaced by safe and environmentally fr...
