preparation example Construction

[0033] The preparation technology in the embodiment of the present invention is as follows:

[0034] (1) Preparation of aqueous mixture:

[0035] At room temperature, mix water-based emulsion, 1 / 2 of water, 1 / 2 of defoamer, all antifreeze, wetting agent, dispersant, preservative, antifungal agent, flame retardant, and rust inhibitor according to weight Mix evenly, then add thixotropic agent and paint film anti-cracking agent in turn and stir evenly to obtain an aqueous mixed solution.

[0036] 2) Filler addition and paint mixing:

[0037] Add all functional fillers, film-forming aids, and 1 / 2 defoamer to the above-mentioned aqueous mixture according to the weight ratio, stir and mix at a high speed, then add the remaining 1 / 2 of water, and finally add an appropriate amount of thickener Adjust viscosity. Among them, the order of antifreeze, flame retardant, and rust inhibitor can be interchanged, otherwise it will cause demulsification and gel phenomenon.

Embodiment 1

[0040] A kind of chassis armor coating of the present embodiment, with aqueous emulsion as main agent; With expanded perlite, expanded vermiculite, talcum powder, kaolin, calcium carbonate, flaky mica powder, hollow microspheres as functional filler; Silicon is used as a thixotropic agent; wood fiber is used as an anti-cracking agent for the paint film; and an appropriate amount of halogen-free environmentally friendly flame retardant aluminum hydroxide, dispersant, wetting agent, anti-corrosion and anti-mold agent, rust inhibitor, flame retardant, etc. are added Various additives for water-based coatings, the main components are proportioned according to the following weight ratio: 30 parts of water-based pure acrylic emulsion; 15 parts of mica powder, 10 parts of hollow glass microspheres, 10 parts of kaolin, 10 parts of calcium carbonate; 1.0 parts of thixotropic 0.5 parts of anti-cracking agent; 5 parts of halogen-free environmentally friendly flame retardant; 5 parts of co...

Embodiment 2

[0050]A kind of chassis armor coating of the present embodiment, with aqueous emulsion as main agent; With expanded perlite, expanded vermiculite, talcum powder, kaolin, calcium carbonate, flaky mica powder, hollow microspheres as functional filler; Silicon is used as a thixotropic agent; wood fiber is used as an anti-cracking agent for the paint film; and an appropriate amount of halogen-free environmentally friendly flame retardant aluminum hydroxide, dispersant, wetting agent, anti-corrosion and anti-mold agent, rust inhibitor, flame retardant, etc. are added Various additives for water-based coatings, the main components are proportioned according to the following weight ratio: 20 parts of water-based pure acrylic emulsion, 20 parts of styrene-acrylic emulsion; 10 parts of mica powder, 5 parts of hollow glass microspheres, 10 parts of expanded perlite, 10 parts 0.5 parts of thixotropic agent; 0.8 parts of anti-cracking agent; 10 parts of halogen-free environmental protectio...

Abstract

The invention discloses a chassis armored coating. The chassis armored coating comprises the following main components in parts by weight: 30-50 parts of waterborne emulsion, 37-60 parts of functional filler, 5-15 parts of coalescing agent, 0.5-1.0 part of dispersant, 0.5-1.5 parts of wetting agent, 0.5-1.0 part of antiseptic mildewproof agent, 0.5-1.0 part of defoaming agent, 0.5-1.0 part of anti-rust agent, 5-20 parts of flame retardant, 0.5-1.0 part of thixotropic agent, 0.5-1.0 of anti-cracking agent, 0.5-1.0 part of thickening agent, 2.0-5.0 parts of antifreeze and 5-15 parts of water. The invention aslo discloses a preparation method of the chassis armored coating. The chassis armored coating uses the water as a dispersion medium, is safe and environmentally-friendly and has excellent corrosion resistance and good solvent resistance and machine oil resistance; a paint film formed by the chassis armored coating has low coefficient of heat conductivity and good thermal insulation property; when the dry film is 2mm, the sound insulation property can reach 30dB.

Description

technical field [0001] The invention relates to the field of vehicle protective coatings, in particular to a chassis armor coating used for vehicle chassis 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 the...
