Embodiment Construction

[0011] An automobile rear axle dipping paint, made of the following raw materials in parts by weight: 55 parts of silicone modified epoxy resin, 45 parts of deionized water, 18 parts of water-based polyurethane resin, 14 parts of cellulose resin, 9 parts of polyester polyol 4 parts, nano-tin oxide 4 parts, silica nanoparticles 1.3 parts, wetting and dispersing agent 1.2 parts, leveling agent 1 part, defoamer 4 parts, thickener 0.8 parts, emulsifier 0.8 parts, modified white carbon 13 parts of black, 10-20 parts of pigment and filler. The preparation method of described modified white carbon black is:

[0012] (1) First crush the silica until the abrasive particle size is less than 300 mesh to obtain a very fine silica grinding dispersion powder, then fully mix the silica with nano-concrete and kaolin, and bake in a vacuum furnace at 600°C for 15 minutes The roasted mixture is obtained, and then the roasted mixture and industrial hydrochloric acid with a concentration of 30% a...

Abstract

The invention relates to automobile rear axle dipping paint which is prepared from the following raw materials in parts by weight: 50-60 parts of organosilicon modified epoxy resin, 40-50 parts of deionized water, 15-20 parts of water-based polyurethane resin, 10-15 parts of cellulosic resin, 8-10 parts of polyester polyol, 3-5 parts of nano tin oxide, 1-1.5 parts of silicon dioxide nanoparticle,1-1.5 parts of a wetting dispersing agent, 0.5-1.5 parts of a flatting agent, 1-5 parts of a defoaming agent, 0.5-1 part of a thickening agent, 0.1-1 part of an emolsifier, 10-15 parts of modified white carbon black and 10-20 parts of pigment and filler. The dipping paint can achieve locking after a certain time and forms a relatively hard external protective film on the surface quickly; the impedance ability and breakdown resistance of a film layer are improved; and a paint material at the top has a good covering effect.

Description

technical field [0001] The invention relates to a paint material, in particular to an automobile rear axle dipping paint. Background technique [0002] The frame is the base body of the car, which is used to fix most of the parts and assemblies of the car, keep them in the correct installation position, and bear various loads from inside and outside the car. At present, there are three structural forms of automobile frames: side beam frame, middle beam frame (or spine frame) and comprehensive frame. After the overall structure of the frame is formed, it needs to be painted or painted on the surface of the frame. Electrophoretic coating forms a layer of protective film on the surface of the frame, that is, paint, to ensure that the frame is not subject to corrosion and oxidation. At present, the better method of painting is electrophoresis, but the cost of electrophoresis is high, especially the maintenance cost. Small axles are not suitable for electrophoresis, so a paint w...
