Abstract
The invention discloses an antiskid powder coating and an online coating method thereof. The antiskid powder coating comprises the following raw materials: phenolic aldehyde modified epoxy resin, a phenolic curing agent for curing the phenolic aldehyde modified epoxy resin and an antiskid agent, wherein the phenolic aldehyde modified epoxy resin and the phenolic curing agent can be subjected to across-linking curing reaction under a curing condition, and the anti-skid agent is used for generating coating anti-skid lines during the curing reaction so that the adhesion force between the coatingfilm and the base material and the anti-skid performance of the surface of the coating film can be improved simultaneously. With creatively screening and designing the characteristics of the raw material formula, the anti-skid property of the coating film can be effectively improved on the premise of ensuring good adhesion performance of the coating film, and the antiskid powder coating is quitesuitable for meeting the requirements of the field of coating protection with excellent anti-skid property requirements.
Description
Technical field [0001] The invention belongs to the field of thermosetting powder coatings, and specifically relates to a non-slip powder coating. The invention also relates to an online coating method of the powder coating. Background technique [0002] The coefficient of friction refers to the ratio of the frictional force between two surfaces to the vertical force acting on one of the surfaces. The performance of this coefficient can directly indicate the anti-skid performance of the surface. In conventional powder coating applications, it is generally not required to have outstanding anti-slip properties. However, with the continuous improvement of environmental protection awareness, people hope that powder coatings can replace conventional paints in more applications, including applications with excellent anti-slip performance. [0003] The applicant conducted a screening test on the existing powder coatings, and found that either the friction coefficient of the powder coatin...
