Problems solved by technology

But the function of painting in this invention gained is more single, can not carry out whole car spraying
[0005] At present, the existing automobile intermediate paint has a single function, and cannot carry out the defects of whole vehicle spraying and non-grinding spray topcoat operation; moreover, the intermediate paint on the market can be grinded in 20 minutes, and the adhesion is 3-4. The sanding time of intermediate paint with adhesion reaching level 1 should be 1 hour, which has the disadvantages of long sanding time and low adhesion

Abstract

The invention belongs to the technical field of automobile coatings and particularly relates to multifunctional rapid intermediate coat for automobiles and a preparation method of the intermediate coat. The multifunctional rapid intermediate coat for the automobiles is prepared from a component A, a component B and a diluent, wherein the component A is prepared from super-fast drying hyperbranchedacrylic resin, low-molecular-weight activated resin, butyl acetate, a dispersant, siloxane coupling agent modified nano-kaolin, ultrafine talc powder, siloxane coupling agent modified nano barium sulfate, an activated siloxane coupling agent, titanium dioxide and organic soil; the component B is prepared from a modified polymer polyisocyanic acid curing agent and butyl acetate; the diluent is prepared from a catalyst and butyl acetate; the weight ratio of the component A, the component B and the diluent is 4:1:1.5-2. The multifunctional rapid intermediate coat for the automobiles can be usedfor whole-automobile spray and polishing-free finishing coat spray, polishing can be performed 20 min after spray at room temperature, and the intermediate coat has good adhesion force.

Description

technical field [0001] The invention belongs to the technical field of automobile coatings, and in particular relates to a multifunctional intermediate coating for extremely fast automobiles and a preparation method thereof. Background technique [0002] Paint is a supporting engineering material that is coated on the surface of an object (to be protected and decorated) and can firmly adhere to a continuous film. The main film-forming material of the paint is composed of grease and polymer materials (resin), non-volatile Reactive diluent is also a film former. It is the main substance for the paint to firmly adhere to the surface of the object to be coated to form a continuous film. It is the basis of the paint and plays a decisive role in the physical and chemical properties of the paint. The paint in the car is also called surfacer, which is between the primer and the topcoat. Its main function is to improve the smoothness of the surface of the substrate and the primer lay...
