Conducting UV wood coating and preparation method thereof

Abstract

The invention discloses a conducting UV wood coating and a preparation method thereof. The conducting UV wood coating is prepared from a preorder coating component and a follow-up coating component. The preorder coating component is a chitosan antibacterial gel and the follow-up coating component is prepared from the following components in percent by mass: an aqueous solution containing 15-20% unsaturated group polyether polyol, an aqueous solution containing 25-30% of unsaturated group polyester polyol, a closed isocyanate crosslinking agent, a defoamer, a vinyl triethoxy ethoxylsilane sealing agent, isopropyl myristate where 10% graphene is dissolved and a mixture extracted from cornu gorais and taking keratin and sterol as a main body. The follow-up coating component is then prepared by carrying out sealing with the vinyl triethoxy ethoxylsilane sealing agent in a saturated manner. The conducting UV wood coating is good in binding force with wood fibers, good in ultraviolet hardening effect, good in conductivity, high-temperature-resistant, wear-resistant and self-hydrophobic.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to a conductive UV wood coating and a manufacturing method thereof. Background technique [0002] Wood products include solid wood and wood-based panel products. The coatings used on wood products are collectively referred to as wood coatings, which include furniture, doors and windows, wall panels, floors, daily necessities, wooden musical instruments, sporting goods, stationery, children's toys, etc. Choose coatings, generally speaking, wood coatings are mainly furniture coatings. [0003] Conductive paint is to add conductive metal powder to specific resin raw materials to make paint coatings that can be sprayed. After drying to form a paint film, it can conduct electricity and shield electromagnetic interference. Shielding is the isolation of metal between two spatial regions to control the induction and radiation of electric fields, magnetic fields and electrom...

AI Technical Summary

Problems solved by technology

[0004] The traditional paint processing mainly uses the traditional polyurethane paint PU solvent-based paint, which requires at least three consecutive spraying, polishing, and a production cycle of several days. A large number of labor requirements and site occupation have caused the furniture industry's profits to drop sharply. The cost continues to increase, and there is still a large VOC, which has an adverse impact on the environment. At the same time, the high temperature resistance performance is not flattering. The static electricity has extremely high requirements, so the woodenware used in these scenes should have a fairly antistatic function, but in fact it is not done at present, but by using a grounded metal container (such as an iron bucket) in a limited area ( Far away from the factory building), it is extremely inconvenient to use (difficult to access)

Since environmentally friendly conductive wood coatings in the full sense have not really appeared, there is still no woodware that has good bonding force with wood fibers, good UV hardening effect, good conductivity, high temperature resistance, wear resistance, and self-repellency on the market. coating
