Abstract

The invention discloses a UV (ultraviolet) solidified organic-inorganic hybridized anti-flaming wear-resistant coating material. A method for preparing the UV solidified organic-inorganic hybridized anti-flaming wear-resistant coating material comprises the following steps: 1) preparing functional sol with a non-hydrolytic sol-gel method; and 2) preparing the coating material. The method comprises the following process of carrying out heating and reacting on a reaction precursor in the presence of a catalyst so as to synthesize the functional sol; and then evenly mixing the sol, UV solidified resin, an active diluent and modified oxide nanometer powder, a photoinitiator, a flatting agent and the like; and finally, forming transparent organic-inorganic hybridized coating material by UV solidification. According to the invention, the light transmittance of the coating can achieve 92%, the adhesive force of the coating is 0 grade, and the abrasion resistance of the coating is less than 0.06g / 100r. The UV solidified organic-inorganic hybridized anti-flaming wear-resistant coating material can be constructed on the surfaces of various base materials (such as glass, metal, plastic and various decoration plates), the original appearance of the base material is kept, and a certain fire resistance property is provided for the UV solidified organic-inorganic hybridized anti-flaming wear-resistant coating material.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a UV curing organic-inorganic hybrid flame-retardant and wear-resistant coating material. Background technique [0002] Since the beginning of the 21st century, with the substantial improvement of my country's per capita living standards, a large number of flammable decorative materials such as wood, fiber, plastic, and rubber have entered the home environment, and the problem of their flame retardancy and fire resistance has become increasingly prominent. UV curable coatings are widely used in the field of building material decoration because of their technical characteristics, but their flammability disadvantages cannot meet the existing development requirements. [0003] Research on the flame retardancy of ultraviolet (UV) curable coating materials mainly includes the application of reactive phosphorus-containing flame retardants, hyperbranched polymers and other additive f...
