Abstract

The invention discloses an easy-toning single-coating elastic coating. The coating is prepared from a component A and a component B, wherein the component A comprises a transparent base material and color paste. A method for preparing the coating comprises the following steps: base material preparation, namely uniformly stirring various components until the fineness is less than or equal to 20mu m and the black matrix glossiness bias is less than or equal to 0.1GU, regulating viscosity, filtering and defoaming; color paste preparation, namely uniformly stirring various components until the fineness is less than or equal to 20mu m and the black matrix glossiness bias is less than or equal to 0.1GU, regulating the viscosity, filtering and defoaming; component A preparation, namely uniformly mixing pearlescent pigment or aluminum powder, the base material and the color paste, regulating viscosity, and filtering; and component B preparation, namely uniformly stirring various components until the fineness is less than or equal to 20mu m and the black matrix glossiness bias is less than equal to 0.1GU, regulating viscosity, filtering and defoaming. The coating prepared by the method has comprehensive excellent performance.

Description

technical field [0001] The invention relates to an easy-to-color single-coat elastic paint and a preparation method thereof. Background technique [0002] Elastic coatings are widely used in the automotive, consumer electronics, and home appliance industries because of their special tactile sensations (such as fluffy, rubbery, etc.), which belong to high-end applications. However, elastic coatings mostly use long-chain linear polyester as the main resin to obtain excellent elasticity while the pigment wetting and dispersibility and color development are not good; and in order to obtain better elastic feel, elastic coatings often require higher film thickness. If it is only used as a topcoat, not only the VOC emission is high, but also the coating cost is expensive. Therefore, single-coat elastic coatings arise at the historic moment. [0003] Colleges and enterprises have been researching single-coat elastic coatings for some time, but they all stay on a few commonly used ...
