High-permeability zero-VOC (volatile organic compound) formaldehyde-free primer for impregnated paper and preparation method of high-permeability zero-VOC formaldehyde-free primer

The invention discloses a high-permeability zero-VOC (volatile organic compound) formaldehyde-free primer for impregnated paper and a preparation method thereof, belongs to the field of impregnated paper adhesives, solves the problem of formaldehyde release caused by urea-formaldehyde adhesives for traditional impregnated paper, and realizes real formaldehyde-free home decoration. According to the formaldehyde-free impregnated primer prepared by the preparation method disclosed by the invention, a permeable monomer is introduced to a resin structure, and the resin is relatively good in water solubility and small in particle size, so that the permeability of a primer solution to paper is improved, and the problem that the paper is easy to break due to non-uniform permeation of the glue solution of the paper is solved; meanwhile, the problem of poor water resistance caused by migration of small molecules due to external addition of a penetrant is also solved. The impregnated paper bottom coating adhesive disclo
