Abstract

The invention relates to the field of coatings and in particular relates to a weather-proof and anti-scratch ultraviolet curing coating used for a wood building material. The weather-proof and anti-scratch ultraviolet curing coating used for the wood building material is prepared from the following raw materials in percent by mass: 30-45% of aliphatic polyurethane hexaacrylate, 3-5% of ethyl cellulose, 5-12% of initiating agent, 1-3% of surface auxiliary, 5-10% of cosolvent, 10-20% of reactive diluent, 1-2% of nano silver antibacterial agent and 10-30% of ethyl alcohol. The weather-proof and anti-scratch ultraviolet curing coating used for the wood building material has good water resistance and scratch resistance, also has an antibacterial function while other physical properties are not influenced and even further has better resistance to soiling, salt fog resistance, ageing resistance, adhesive force and cold shock resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a weather-resistant and scratch-resistant UV-curable coating for wooden building materials. Background technique [0002] Since the advent of UV-curable coatings, it has the characteristics of 5E, namely Efficient, Enabling, Economical, Energy Saying, and Environmental-friendly. In the prior art, UV-curable coatings have been widely used in fields closely related to life to beautify and protect objects. [0003] Coatings can effectively protect wooden building materials from corrosion, thereby prolonging the service life of wooden building materials. In addition, wooden building materials appear more beautiful under the coating of paint. However, the existing coatings for general wooden building materials have poor effects, and general weather resistance and scratch resistance, so the service life has been greatly affected. Contents of the invention [0004] The purpose of the present...
