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 UV resin for a four-arm astral symmetrical multi-block matte coating and a preparation method of the UV resin. According to the UV resin for the four-arm astral symmetrical multi-block matte coating, four symmetrical long chain segments are formed in a molecular structure, and each molecular chain sequentially contains a polyurethane subchain segment, a polyethylene glycolsubchain segment, a polyurethane subchain segment and an acrylic ester subchain segment from the center to the periphery. The UV resin for the four-arm astral symmetrical multi-block matte coating isfree from solvents, single-component and rapid to solidify, and has stable matte effect.

Description

technical field [0001] The invention relates to the technical field of UV photocurable resins, in particular to UV resins for four-arm star-shaped symmetrical multi-block matte coatings 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. Due to its environmental protection, no VOC emissions, low energy consumption, fast curing and other ...
