Aqueous UV wood paint, preparation method and application technology thereof

Abstract

The invention discloses an aqueous UV wood paint. The aqueous UV wood paint comprises the following components: 20-40% of aqueous polyurethane resin, 20-60% of aqueous UV resin, 0.2-0.6% of an antifoaming agent, 0.2-0.8% of a leveling agent, 0.2-0.8% of a wetting agent, 0.2-0.8% of a thickening agent, 0.2-0.8% of an initiator, 0.2-0.8% of a dispersant, 0.2-0.8% of matting powder, 5-40% of water, and 0.2-0.5% of a handfeel auxiliary agent. The invention also discloses a preparation method of the aqueous UV wood paint and an application technology thereof. The aqueous UV wood paint has the advantages of good environmental protection performance, strong adhesive force, high hardness, good wear resistance and coin scratching-resistant performance. The preparation method has the advantage of simple operation, by employing a microwave drying method, the drying speed is fast, drying requirement of a thicker coating can be satisfied, the production efficiency is high, and the aqueous UV wood paint is quit suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a water-based UV wood coating and its preparation and application process. Background technique [0002] The natural and soft touch of traditional polyurethane coatings has become a pursuit of high-quality life. However, due to the high VOC content of traditional coatings, the serious impact on the environment and the body limits its use. Water-based UV coatings inherit and develop the traditional The dual advantages of UV coatings and water-based coatings, such as environmental protection and high efficiency, low viscosity, excellent coating performance, easy cleaning of equipment, non-toxic, non-flammable, etc. Because of its outstanding advantages, water-based UV coatings have developed rapidly in the field of wood coatings in recent years. However, water-based light-curing coatings also have some disadvantages. Before curing, they need to be dried to remove water, ...

AI Technical Summary

Problems solved by technology

Although the hot air drying equipment is simple to invest, but the temperature is too low will prolong the pre-baking time, affect the production efficiency, and may cause moisture residue to prolong the curing time and affect the performance of the paint film

Infrared heating drying is faster than hot air drying, but it will produce a significant temperature gradient. Its drying is extended from the surface to the inside, which makes it not suitable for drying thicker coatings. Infrared drying can only be heated by infrared rays. It cannot be used to dry three-dimensional objects, and the energy consumption of infrared drying is also relatively large.
