Abstract

The invention discloses a PU transparent primer as well as a preparation method and application thereof. The PU transparent primer comprises a main agent, a curing agent and a diluent, wherein the main agent comprises the preparation raw materials: odorless alkyd resin, butyl acetate, fatty acid zinc powder, granular powder, an anti-settling slurry semi-finished product and a VAGH liquid semi-finished product. The primer provided by the invention contains the main agent, the curing agent and the diluent, primer coating can be conducted after the main agent, the curing agent and the diluent are directly and sufficiently stirred to be uniform, use is easy and convenient, and applicability is high. The primer has the advantages of being odorless, high in flexibility, cracking-resistant, high in transparency, good in grinding property and filling property, capable of enabling a veneer decorative surface to be not prone to color change and color fading, capable of preventing sinking and the like, and is especially suitable for preparation of ebony products.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a PU transparent primer and a preparation method and application thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] Wood products widely exist in various places of human life, such as furniture, doors and windows, wall panels, floors, daily necessities, wooden musical instruments, sporting goods, stationery, children's toys, etc., all of which can be made of wood. Unlike other materials, wood has a range of variability, including density, durability, dimensional stability and absorbency,...
