Problems solved by technology

At present, the chassis armor on the market is mainly various asphalt coatings. Although asphalt coatings have excellent anti-corrosion properties, their shortcomings are also obvious. The main manifestations are: (1) Asphalt is easy to drip when the temperature of the bottom of the vehicle is high in summer. Harmful gas infiltrates into the compartment and endangers the health of the owner; (2) The asphalt paint film is easy to become brittle, harden and fall off in the later stage, has poor aging resistance, and is not resistant to gasoline; (3) Asphalt materials are flammable; (4) When the vehicle is running at high speed, The sound insulation effect on gravel impact sound and wind noise is poor

Abstract

The invention provides damping paint for automotive chassis armoring. The damping paint comprises the following raw materials: 145-155 parts of waterproof acrylic acid emulsion, 45-55 parts of anti-rust emulsion, 95-105 parts of plasticizing acrylic emulsion, 145-155 parts of pure acrylic emulsion, 13-17 parts of a coalescing agent, 478-522 parts of functional filler, 23-27 parts of a flame retardant and 1.5-2.5 parts of an adhesive. The damping paint is free of environmental pollution, resistant to stone chips, acid, base and salt spray and the like.

Description

technical field [0001] The invention belongs to the technical field of damping paint, and in particular relates to a damping paint for automobile chassis armor. Background technique [0002] At present, there are many types of damping coatings at home and abroad, but from the solvent of the coatings, there are mainly two types: solvent-based and water-based. Most of the former contain organic solvents and asphalt, which are highly toxic, highly volatile, pollute the environment, and have poor workability, so they are rarely used now. The latter damping coating uses water as a solvent, has low toxicity, low odor, low cost, easy construction, and environmental protection, and is the first choice for damping coatings for urban rail vehicles. [0003] Chassis armor can effectively protect the vehicle chassis from being hit by road sand and gravel, prevent slight dragging friction; prevent acid, alkali, and salt from corroding the chassis iron plate; prevent chassis screws from ...
