Abstract

The invention provides an anti-collapse high-fullness mirror surface gloss varnish, which is prepared from components A, B and C with a weight proportion being 1:(0.8 to 1):0.5, wherein the componentA is prepared from a coconut oil fatty acid resin, an acrylic resin, a synthetic fatty acid alkyd resin, a flatting agent, a defoaming agent and a solvent; the component B is prepared from a TDI-HDI mixed tripolymer or a TDT / TMP additive product, an HDI tripolymer and a solvent; the component C is prepared from xylene, butyl acetate and a multifunctional solvent. The invention also provides a preparation method of the anti-collapse high-fullness mirror surface gloss varnish. The anti-collapse high-fullness mirror surface gloss varnish provided by the invention is low in VOC (Volatile Organic Compounds) content and high in solid content, a coating film is glossy, fast in surface dry and curing speed, not easy to collapse, high in fullness, capable of achieveing a mirror surface effect and good in durability, a thicker coating film can be obtained through one-time construction, and the gloss varnish is widely applicable to surface coating of musical instruments, high-end furniture and woodware.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an anti-collapse high-fullness mirror gloss varnish and a preparation process thereof. Background technique [0002] Wood product coating pursues the fullness and decorativeness of the paint film. As a high-end decorative paint, gloss varnish is more and more favored by consumers. Existing gloss varnishes generally have defects such as poor fullness, poor gloss retention, poor weather resistance, and easy collapse, which seriously affect the coating effect and cannot meet the needs of the high-end market. [0003] CN103937401B provides a kind of anti-scratch two-component polyurethane wood varnish, composed of alkyd resin, acrylic resin, aldehyde ketone resin, chelating leveling agent, defoamer and solvent A component and TDI-HDI mixed trimer Or TDI / TMP adduct, HDI trimer and solvent B component, its high solid and low viscosity, good leveling, high gloss, rich texture, mirror ...
