Description
Technical Field
The invention relates to the technical field of coatings, in particular to PU transparent primer for preventing 'catheter bulge' and a preparation method thereof.
Background
In the furniture industry, the 'guide pipe bulge' is a common defect in the construction of solid wood or veneer furniture, and the whole wood guide pipe can show the 'bulge' phenomenon after the surface of the furniture is coated with finish paint and dried; over time, the 'bulging' phenomenon can slowly disappear until the 'guide tube sinking' condition is formed, so that the coating film is hollow and uneven, the appearance of the furniture is seriously affected, and the grade of the furniture is further reduced.
Among these, the reason for the formation of the "duct hump" is: (1) the wood conduit is continuously extended, and after the PU primer is coated, the PU primer can penetrate into the deep part of the wood along the conduit, so that the solvent in the PU primer cannot be fully volatilized; in addition, the main agent and the curing agent do not react completely, so that the final coating film is soft. (2) When the finish paint is coated, because the strong solvent (such as esters) in the finish paint is more, the strong solvent can continuously permeate to the deep part of the conduit along the lower soft coating film, and then slowly volatilize to jack up the coating in the conduit, which is expressed as a 'conduit bulge' condition.
