Embodiment 1

[0015] The component of the ultraviolet curing nanometer antibacterial woodware paint of the present embodiment is as follows: as the bisphenol A epoxy acrylate of epoxy acrylate; As the aromatic urethane acrylate SM6201 of urethane acrylate; As diluent butyl acrylate, Trimethylolpropane triacrylate (TMPTA) and tripropylene glycol diacrylate (TPGDA); silver-loaded inorganic nano-antibacterial agents as inorganic nano-antibacterial agents; nano-zinc oxide and nano-silica as inorganic nano-fillers; 2-Hydroxy-2-methyl 1-phenyl-1-propanone (Darocur1173) as initiator; EFKA4010 dispersant as dispersant; Deqian 837 leveling agent as leveling agent.

[0016] The specific parts by weight of each component are: 40 parts of bisphenol A epoxy acrylate, 15 parts of aromatic urethane acrylate, 10 parts of butyl acrylate, 5 parts of trimethylolpropane triacrylate (TMPTA), 2 parts of tripropylene glycol 20 parts of acrylate (TPGDA), 1 part of silver-loaded inorganic nano-antibacterial agent, ...

Embodiment 2 to Embodiment 48

[0023] The preparation method of the UV-curable nanometer antibacterial wood lacquer of embodiment 2 to embodiment 48 is basically the same as embodiment 1, and the numerical values ​​of its components and corresponding weight proportions (expressed in parts by weight) are shown in Table 1 to Table 8 , The specific data of performance tests such as adhesion, pendulum hardness, abrasion resistance, dry heat resistance, and antibacterial rate against Escherichia coli and Staphylococcus aureus are shown in Tables 1 to 8 (the symbol " / " in the table means no).

[0024]Among them, there is no dispersant and leveling agent in Examples 6, 10, and 11. Compared with the corresponding examples with dispersant and leveling agent, the abrasion resistance is slightly lower, but the relevant indicators still meet the relevant national standards.

Abstract

The present invention discloses one kind of ultraviolet ray cured nanometer antibiotic woodenware lacquer and its preparation process. The ultraviolet ray cured nanometer antibiotic woodenware lacquer includes epoxy acrylate, polyurethane acrylate, diluent, nanometer inorganic antiseptic, nanometer inorganic stuffing and photoinitiator. The preparation process includes adding nanometer inorganic antiseptic and nanometer inorganic stuffing into the diluent, stirring to disperse homogeneously, adding epoxy acrylate, polyurethane acrylate and photoinitiator and mixing homogeneously. The woodenware lacquer with nanometer inorganic antiseptic can inhibit the growth and propagation of bacteria and microbes to produce long term antibiotic effect.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet light-curable wood lacquer, and in particular relates to an ultraviolet light-curable nano wood varnish and a preparation method thereof. Background technique [0002] UV-curable coating is an environmentally friendly and energy-saving coating developed in the 1960s. It has no or low volatile organic compound (VOC) emissions and saves energy (energy consumption is only 1 / 5 to 1 / 3 of that of heat-cured powder coatings. 10), fast curing speed (0.1 ~ 10s), suitable for assembly line production, low curing temperature, suitable for coating heat-sensitive skidding, etc. With the improvement of national environmental protection regulations, reducing the use of volatile organic compounds in coatings has become an inevitable trend, and UV curing technology is one of the effective measures to solve this problem. Over the past 40 years, with the rapid development of photocuring technology, UV-curable c...
