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 three-arm star-shaped multi-block UV resin for a matte coating and a preparation method thereof. The three-arm star-shaped multi-block UV resin for the matte coating is characterized in that the molecular structure of the three-arm star-shaped multi-block UV resin for the matte coating has three chain segments; each molecular chain sequentially contains high-flexibility polyurethane sub chain sections, easy-to-crystallize polyethylene glycol sub chain sections, high-flexibility polyurethane sub chain sections and acrylate sub chain sections from the center to the periphery; the structural formula is shown as a formula (I), wherein n is an integer being 22 to 440. The three-arm star-shaped multi-block UV resin for the matte coating is solvent-free UV curing resin; the matte effect can be generated without the addition of fillers; the matt coating prepared by the resin has a matte effect; the hardness and the flexibility can be realized. (The formula (I) is shownin description.).

Description

technical field [0001] The invention relates to the technical field of UV photocurable resins, in particular to a UV resin for three-arm star-shaped multi-block matt coating 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.
