Abstract

The invention discloses a bicomponent water-borne paint with an orange peel texture / ripple effect. The paint comprises a main preparation and a water-borne curing agent in a mass ratio of (3-6):1, wherein the main preparation is prepared from the following components in parts by mass: 50-80 parts of resin, 0-2 parts of a conventional auxiliary, 0.1-0.5 part of a flash-rust inhibiting agent, 0.2-2 parts of ripple auxiliary, 5-30 parts of a pigment, 7-15 parts of distilled water and 0.2-5 parts of an anti-settling agent. The invention further discloses a method for preparing the paint. The paint has a simple formula, remarkable orange peel texture / ripple after a film is formed, and strong sense of three-dimensional coating surface.

Description

Technical field [0001] The present invention relates to a water-based paint, in particular to a two-component water-based paint capable of producing orange lines / corrugation effects, and also relates to a preparation method of the paint. Background technique [0002] Corrugated paint is a kind of paint. Its coating surface has an orange pattern / corrugated effect, strong adhesion, fast drying of the paint film, strong corrugated three-dimensional effect, better decorative effect than other topcoats, and can hide general roughness Substrate. Corrugated paint is a new type of high-end industrial art paint that is widely used by domestic machinery manufacturers. It has excellent performance and is suitable for coating equipment such as cabinets, punches, plastic auxiliary machines, hydraulic presses, and processing centers. Water-based paint is a recognized eco-friendly, low voc emission paint product, and is also a product advocated by the country. It entered China in the 1990s an...
