Method of testing, comprise the following steps：1) color essence is added into the colored varnish and is configured to coloured enamel；2) sheet material is provided, described
The coloured enamel is sprayed on sheet material, forms coloured enamel layer；3) seal coat is sprayed on the coloured paint film layer, forms priming paint
Layer；4) white finish paint is sprayed on the prime coat, forms white top coat layer；5) observe whether the color essence migrated in one week
The white top coat layer is infiltrated into, if there is color essence migration infiltration, judges that seal coat is unqualified；If do not occur color essence migration to ooze
Thoroughly, judge that seal coat is qualified.
Preferably, in step 1), the weight fraction of the essence of color described in the coloured enamel is 3-8%.
Preferably, the step 2) is also included after the coloured enamel is sprayed on sheet material, and the coloured enamelled coating is carried out
Dry step.
Preferably, the mode coloured enamelled coating being dried is toasts at 40-50 DEG C, baking time 3-6h.
Preferably, it is air drying to the mode that the coloured enamelled coating is dried, drying time 20-30h.
Preferably, the sheet material is selected from any one of density board, solid wood board and wood-based plate.
Preferably, in step 2), the spreading rate of the coloured enamel is 8-10m2/kg。
Preferably, in step 3), the spreading rate of the priming paint is 8-10m2/kg。
Preferably, the step 3) is also included after spraying seal coat on the coloured paint film layer, to the priming paint
The step of layer is dried.
Preferably, the mode prime coat being dried is air drying, drying time 20-30h.
Preferably, in step 4), the spreading rate of the white finish paint is 8-10m2/kg。
In summary, the present invention provides a kind of method of testing of permeation-proof color seal coat, beneficial effects of the present invention：
The present invention by first spraying one layer of coloured enamel before spray-applied primer, coloured enamel prepared by color essence and the colored varnish and
Into because color essence particle diameter is small, permeability is strong, and bright-colored, is easy to observe the sealing effect of seal coat, so as to test out
The closed performance of seal coat.Relative to method of testing in the prior art, the present invention is capable of the performance of fast verification seal coat,
The testing time is saved, substantially increases operating efficiency.
