Problems solved by technology

In the early stage of development, it was mainly prepared from acrylic resin, toner, filler, and solvent. Later, phenolic resin wrinkle paint and alkyd resin wrinkle paint were developed, but some inorganic fillers were added to these wrinkles. Adding can increase the effect of wrinkles to a certain extent, but because the inorganic fillers are easy to agglomerate in the system, the wrinkles formed are irregular, and it will also reduce the adhesion of the paint film on the substrate
[0003] At present, the wrinkle paints on the market often use spraying, brushing, and rolling processes. Among them, the spraying process is used more, but the efficiency of the spraying process is relatively low, and the output cannot be greatly improved. For some irregular or Substrates with unsuitable sizes cannot be sprayed. Although there are a small number of wrinkle paints on the market that use the dip coating process, the products made by this process have poor leveling and the wrinkle effect is not uniform.

Abstract

The invention relates to the technical field of coatings, in particular to efficient dip-coating process effect paint and a preparation method thereof. The effect paint is prepared from the following raw materials in percentage by weight: 50 to 70 percent of modified alkyd resin, 7 to 12 percent of tung oil, 0.8 to 3.5 percent of drier, 0.5 to 1.5 percent of flatting agent and the balance of solvent. A paint film of the effect paint is high in wrinkling speed and can be rapidly leveled, wrinkles of the paint film formed on a base material are regular and appropriate and identical in size, and the effect paint further has good adhesive force.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an efficient dip coating process effect paint and a preparation method thereof. Background technique [0002] The wrinkle paint is named by adhering to the surface of the substrate to form a pattern like a ripple. The wrinkle can be used for decoration, can be used for the decoration of the surface of the substrate, and also has a protective effect on the surface of the substrate, which is widely used. In the early stage of development, it was mainly prepared from acrylic resin, toner, filler and solvent. Subsequently, phenolic resin crepe paint and alkyd resin crepe paint were developed, but some inorganic fillers were added to these wrinkles. Addition can increase the effect of wrinkles to a certain extent, but because inorganic fillers are easy to agglomerate in the system, the formed wrinkles are irregular, and at the same time, the adhesion of the paint film on the substrat...
