Problems solved by technology

At present, there are very few studies on bead point oil, and most of them rely on spraying techniques to form bead point effects. Generally, different paints must be sprayed several times during painting. This construction process not only has extremely high requirements for construction personnel, paints, and equipment. , and the formed coating film is uneven, the adhesion is poor, and the formed beads are uneven, dull and easy to fall off

Abstract

The invention relates to the field of coatings, in particular to bead point oil as well as a preparation method and a construction process thereof. The bead point oil comprises the following raw materials in parts by weight: 40-60 parts of unsaturated polyester resin, 20-40 parts of a vinyl prepolymer, 0.2-3.0 parts of a slipping aid, 0.05-0.5 parts of an initiator and 0.01-0.05 parts of a polymerization inhibitor. The bead point oil provided by the invention is good in component compatibility and can be stably stored for a long time, a coating film formed on the surface of a substrate is continuous and uniform and good in adhesive force, and a formed bead point is good in effect and not easy to fall off. In addition, the solid content of the bead point oil is as high as 70% or above, andthe bead point oil is green, environment-friendly, capable of being applied at the first attempt by adopting a roll-coating or spray-coating process, simple to operate and low in cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a bead point oil, a preparation method and a construction process thereof. Background technique [0002] Art paint, also known as art paint, is a paint variety with special performance composed of special materials, and belongs to industrial paint. Like conventional paints, art paints are applied on the surface of objects to protect the surface of objects, but in addition, art paints will form various beautiful patterns, patterns, water drops and other effects after film formation, which has a good effect on the surface of objects. decorative. As people's pursuit of beauty becomes more and more prosperous, various personalized art coatings are favored, especially in the packaging industry. [0003] Bead point oil is a kind of art paint. After coating, it can form crystal clear particles on the surface of the object, like dew in the morning, which is very beautiful. At present, there ar...
