Problems solved by technology

[0003] At present, the paint used in this roller coating process is mainly oil-based UV paint, but the coating amount of oil-based UV paint is difficult to control, which will affect the gloss of the paint film, and a large amount of organic solvents volatilize during the coating process, which is not environmentally friendly and even affects People's health is unstable when attached to PETG film or PVC film, which affects the appearance and quality of wooden doors

Abstract

The invention discloses a preparation method of water-based zero-degree skin-touch UV paint, which comprises the following steps: step (1), preparing raw materials, the raw materials comprise the following components in percentage by mass: 60%-80% of a 530 water-based UV emulsion, 5%-15% of a 726 water-based UV emulsion, 1%-3% of DPNB, 0.4%-1.2% of DPM, 0.1%-0.3% of tego902W, 0.2%-0.4% of tego4100, 0.4%-0.6% of DC-51, 0.4%-0.6% of tegoLP10, 1%-3% of an initiator A, 0.4%-0.6% of an initiator B, 0.1%-0.3% of RM-2020, 0.2%-0.4% of Hamming 299 and 8%-16% of water. The coating weight is easy to control, a paint film is uniform in gloss and good in adhesive force, very low VOC is released in the coating process, and the coating is environmentally friendly and durable.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a method for making water-based zero-skin UV paint and a method for using the same. Background technique [0002] In view of the current popular finishing materials and processes for wooden doors on the market, it has been gradually transformed from the past coating paint to soft plastic film covering. This method has high efficiency, good durability, easy color change, and is suitable for mass production. . The soft materials used for coating mainly include PETG, PVC, etc. UV paint is applied on these plastic films, and after curing, it becomes a pre-coated coil, and then according to the size of the wooden door, it is covered with negative pressure in the wooden door factory. During the production process High efficiency, energy saving and environmental protection. [0003] At present, the paint used in this roller coating process is mainly oil-based UV paint, but the coating ...
