Abstract

The invention discloses a robot sprayed automobile intermediate coating, and belongs to the technical field of automobile coatings. The automobile intermediate coating includes a main paint, a curing agent and a diluent, and the main paint comprises, by weight, 20-30 parts of acrylic resin, 5-10 parts of polyester resin, 20-30 parts of titanium dioxide, 5-20 parts of ultrafine talcum powder, 0.5-1.5 parts of fumed silica, 0.5-1.5 parts of a wetting dispersant, 3-10 parts of a conductive agent, 0-5 parts of a conductive assistant and 15-20 parts of a solvent. The settlement resistance of the coating is improved by selecting lightweight color fillers and adjusting the binder ratio of the intermediate coating in order to realize good long-distance pipeline conveying. In addition, the conductive agent and the conductive assistant are compounded according to a certain ratio to adjust the conductivity of the intermediate coating to 15-40Momega in order to adapt to the robot spraying and the cost of the intermediate coating.

Description

technical field [0001] The invention relates to a robot spraying automobile surfacer, which belongs to the technical field of automobile coatings. Background technique [0002] Automobile surfacer is a coating used between the automobile primer and the topcoat. Automobile secondary primer requires not only to be firmly attached to the surface of the primer, but also to be combined with the topcoat on it, which plays an important role in linking the preceding and the following. In addition to the requirements of good adhesion and bonding with the upper and lower coatings, the automotive secondary primer also requires good mechanical properties, which can provide protection properties suitable for the top coat, as well as suitable electrical conductivity and good settlement resistance, so that It is suitable for long-distance pipeline transportation, which is convenient for pipeline cleaning. [0003] At present, the automotive surfacer on the market is mainly used for manua...
