Embodiment 1～6

[0026] A kind of sprayed wood lacquer suitable for UV-LED curing, the mass fractions of the raw materials in Examples 1 to 6 are listed in Table 2.

Embodiment 1

[0027] In Example 1, the weight ratio of the modified polyester acrylate resin and the hexafunctional aliphatic urethane acrylic resin is a mixture of 2.5:1; among the photoinitiators, photoinitiator TPO: photoinitiator ITX=2.0:1; active dilution The agent is HDDA and DPGDA=1:3.4; the weight ratio of BYK-405 and AEROSIL R972 in the anti-settling agent is 1:3.

Embodiment 2

[0028] In Example 2, the weight ratio of the mixture of the modified polyester acrylate resin and the hexafunctional aliphatic urethane acrylic resin is = 2.9:1; the photoinitiator TPO in the photoinitiator: the photoinitiator ITX = 2.5:1; the active The diluents are all DPGDA; the weight ratio of BYK-405 and AEROSIL R 972 in the anti-settling agent is 1:3.

Abstract

A spray wood paint for UV-LED curing of the present invention comprises the following raw materials in mass fraction: acrylic resin: 30%-45%, photoinitiator: 5%-8%, talcum powder: 10%-20% , dispersant: 0.1% to 2%, reactive diluent: 36% to 46%; the weight ratio of the acrylic resin to modified polyester acrylate resin and hexafunctional aliphatic polyurethane acrylic resin is (2.0 to 3.5): 1 mixture. The invention uses a reciprocating automatic spraying machine for fast coating, infrared leveling lines for leveling, and LED curing equipment for curing, which not only sprays more evenly, saves time and space to be dried, and reduces energy consumption; it does not contain volatile organic compounds , greatly reducing environmental pollution; reducing man-made instability; less paint waste, saving paint and labor costs, and improving the market competitiveness of products.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a sprayed wood paint for UV-LED curing. Background technique [0002] The first patent for ultraviolet (UV) curing coatings was born in 1947. After more than half a century of development, UV curing coatings have become a relatively mature technology, especially with the improvement of people's awareness of environmental protection, production and researchers pay more attention Development and application of UV-curable coatings. [0003] UV light-curing coating is a kind of high-efficiency, environmental protection, energy-saving and high-quality light-curing material. UV-curing coating is a kind of green and environment-friendly coating, which fully conforms to the "4E" principle. Generally, the energy consumption of UV curing is 1 / 5 of that of thermal curing. , and the UV-curable coating contains less volatile components and less pollution, which can reduce the co...
