Abstract

The invention relates to a low-temperature resistant UV (Ultraviolet)-curable coating material. The low-temperature resistant UV-curable coating material is prepared from the following raw materials in parts by weight: 40-45 parts of polyurethane acrylate prepolymer, 14-18 parts of epoxy acrylate, 5-7 parts of hydroxypropyl methacrylate, 8-12 parts of meerschaum powder, 3-5 parts of linoleic acid, 4-6 parts of dioctyl phthalate, 4-8 parts of methyl ethyl ketone, 1-2 parts of benzil dimethyl ketal, 10-14 parts of maleic anhydride, 3-6 parts of ammonium polyphosphate and 4-5 parts of auxiliaries. The UV coating material disclosed by the invention has high wear resistance, high adhesive power, high flexibility, high peeling strength, excellent low-temperature resistance and outstanding optical properties and weatherability; through adding the meerschaum powder, the shrinking percentage is lowered, a coating is difficult to crack, and the flame retardance is improved; the coating material further has the characteristics of low content of VOC (Volatile Organic Compounds), good decorative effect, high curing speed, easiness in construction, being suitable for assembly line production and the like, and can be applied to the decoration of base materials, such as plastics, woodenware, metals and the like; due to the auxiliaries, the dispersity of the coating material is improved, the leveling property is good, and a coating layer is smooth and bright.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a low-temperature resistant UV light-curing coating and a preparation method thereof. Background technique [0002] The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter, which are energy-saving, resource-saving, pollution-free, and high-efficiency; but there are still some shortcomings, such as free radical type The curing process of light-curing coatings is inhibited by oxygen, poor surface curing, and a series of problems such as yellowing, explosive color, low temperature resistance, high cost, and poor corrosion resistance, all of which need to be continuously improved for different purposes to reduce production costs , to expand the use. Contents of the invention [0003] The object of the present invention is to provide a kind of low temperature resistant UV photocuring...
