Embodiment 4

[0020] The coating described in Example 4 is applied on the decorative wood surface layer by roller coating, flow coating, spray coating, or dip coating, and the resulting coating film has good abrasion resistance.

Embodiment 5

[0021] The coating described in embodiment 5 is a white paint film with good hiding power, which is used to produce white UV cured woodware.

[0022] The main production method of the present invention is to pre-disperse specially modified nano-materials and appropriate monomers, then add other materials and pre-dispersed nano-materials into the reactor in sequence, and slowly heat up, adjusting the temperature to 55- 65°C / 1hr, pump into the reactor, add photosensitive diluent and mix at 50~60°C / 2hr, then add photosensitive curing synergist and other additives.

[0023] Nanotechnology is a hot research topic in the world in the 21st century. Using nanotechnology to modify UV-cured wood coatings will not only upgrade UV coating products, but also promote the expansion of UV coatings to high-tech fields (such as aerospace, electronic materials) and other fields.

Abstract

The modified ultraviolet cured woodenware paint consists of one or several of nano silica, zirconia, titania, zinc oxide, negative ion powder, antibiotic material, far infrared powder, antistatic powder and alumina in 0.3-20 wt% and active oligomer comprisnig acrylic epoxy resin, acrylic polyurethane and acrylic amino resin in 30-76 wt%. The modified ultraviolet cured woodenware paint has the small size effect, surface effect, quantum size effect and macroscopic quantum tunnel characteristic of nano material, so that it has high antiwear property, hgih surface hardness, high toughness, high cracking resistance and many other advantages.

Description

technical field [0001] The invention relates to an ultraviolet light curing coating for wood products, in particular to a nano material modified ultraviolet light curing wood coating. Background technique [0002] Ultraviolet (UV) curing wood coating is a high-tech industry that has developed vigorously in China in the past ten years. Ultraviolet (UV) curing generally refers to the rapid polymerization of solvent-free liquid chemicals by ultraviolet (UV) radiation, which enables rapid curing of coatings, inks and adhesives. The feature of this technology is zero emission and zero waste treatment in the production and use environment. The use of this technology greatly reduces the entry of volatile organic compounds (VOC) into the environment, avoiding the resulting greenhouse effect that is more serious than carbon dioxide, and in sunlight Formation of oxides and photochemical smog under exposure to sunlight. This is of great significance for ...
