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 puts forward a chassis armor coating and a preparation method thereof. The chassis armor coating comprises the following raw materials (by weight): 145-155 parts of a styrene-acrylic emulsion, 55-65 parts of a plasticizing acrylic emulsion, 35-45 parts of a water-proof emulsion, 45-55 parts of an antirust emulsion, 145-155 parts of a pure acrylic emulsion, 13-17 parts of a coalescing agent, 23-27 parts of a preservative, and 537-598 parts of a functional filler. The preparation method comprises the following steps: weighing the styrene-acrylic emulsion, the plasticizing acrylic emulsion, the water-proof emulsion, the antirust emulsion and the pure acrylic emulsion, mixing and uniformly stirring for 8-12 min, adding the coalescing agent and the preservative and stirring for 4-6 min, adding the functional filler and uniformly stirring for 55-65 min. the coating has good acid and alkali resistance, solvent resistance and good thermal insulation property, and can reduce noise generated by rock shock and vibration.

Description

technical field [0001] The invention belongs to the technical field of protective paint for passenger cars, and in particular relates to a chassis armor paint and a preparation method thereof. Background technique [0002] 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 loosening; reduce noise transmission during driving, increase Driving tranquility; preventing the heat conduction of the chassis iron plate, so that the cab is warm in winter and cool in summer. 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 ...
