Problems solved by technology

However, it is difficult for the added inorganic filler and the organic system of the paint to dissolve perfectly, and an unstable state such as separation will inevitably occur after long-term storage. In the later storage and use, the sedimentation of the filler may cause the inorganic filler to be located at the bottom of the container, affecting the later coating. Cloth effect, causing adverse effects on production

Abstract

The invention discloses water-based three-arm star-shaped multi-block ultraviolet-curing resin and a preparation method thereof. The water-based three-arm star-shaped multi-block ultraviolet curing resin provided by the invention is provided with three crossed long chain segments, and each molecular chain sequentially contains a polyurethane sub-segment, a hydrophilic chain-expanding group, a polyurethane sub-segment, a polyethylene glycol sub-segment, a polyurethane sub-segment, a hydrophilic chain-extension group, a polyurethane sub-segment and an acrylate sub-segment from center to periphery. The preparation process of the water-based three-arm star-shaped multi-block ultraviolet curing resin disclosed by the invention is green and pollution free, has no emission problem of VOC (volatile organic compounds), accords with the low-carbon environment protection idea, and can be used to prepare a single-component coating system. The viscosity of the system can be adjusted, so that the coating process difficulty is greatly reduced. In addition, a good matte effect is generated through different crystallization performance and micro compatibility of different sub-chain segments in theresin molecular chains.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing resins, in particular to a water-based three-arm star-shaped multi-block ultraviolet light curing resin and a preparation method thereof. Background technique [0002] With the upgrading of social industrial level and people's consumption level, consumers have more and more strict requirements on the appearance, touch and experience comfort of daily necessities and industrial products. Many high-end products have begun to attract the attention of the public with their beautiful and comfortable appearance and touch. The application of matte coating also arises at the historic moment. With its beautiful appearance and comfortable human physiological touch, it has gradually occupied a place in the automotive interior, electronic products and other industries, and has gradually gained more favor. Ultraviolet (UV) curing technology has become a new technology of green coating materials with gr...
