Emulsion paint film maintaining device and test method of color-modulable emulsion paint color stability

Abstract

The invention discloses an emulsion paint film maintaining device, which comprises a tank body with ventilation openings on opposite side walls, a magnifying lens panel inlaid on a top wall of the tank body, LED (Light-emitting Diode) lamp beads arranged on edges of the magnifying lens panel, a short wave infra-red light heating lamp arranged on an inner surface of the top wall of the tank body, asample table arranged on a bottom wall of the tank body, a thermoinduction element arranged on an edge of the sample table, and a controller device, wherein a side door is also arranged on one side wall of the tank body; the control device is connected with the LED lamp beads, the short wave infra-red light heating lamp and the thermoinduction element. The invention also discloses a test method of color-modulable emulsion paint color stability. The test method of the color-modulable emulsion paint color stability is clear in operation, so that repeated trials caused by test errors or personalerrors or test inconvenience are effectively reduced; by using the emulsion paint film maintaining device, the test period is greatly shortened, the production efficiency is effectively improved, andthe device has a higher practical value.

Description

technical field [0001] The invention relates to the testing field of latex paint. More specifically, it relates to a latex paint film maintenance device and a test method for the color stability of the adjustable latex paint. Background technique [0002] The market's requirements for the variety of colors in the modern coating system have promoted the transformation of paint companies from traditional production to innovative development. Major companies have created personalized color matching systems according to the paint market positioning and the characteristics of the objects used. Changes in demand and the emergence of new coating substrates are constantly improving and expanding, avoiding the outdated color matching system due to the passage of time, and products driven by color culture are emerging in an endless stream. The biggest difference between color-tunable latex paint products and non-color-color latex paint products is the requirement for color stability....

Problems solved by technology

[0004] Although the above method stipulates the mixing method of sample paint and color paste and the method of preparation and maintenance of paint film, there is no clear regulation on the stirring time after mixing sample paint and color paste. For inexperienced operators, it may be difficult to understand the uniform mixing. There will be deviations; the national standard "GB / T 21090-2007 Colorable Latex Base Paint" requires that the sample paint to be tested and the color paste be added according to the mass ratio. It is calculated by volume ratio, which leads to the deviation between the factory inspection and the actual construction operation in the market; the requirement of testing the coating film after drying for 24 hours in the test environment of GB / T9278 greatly limits the improvement of production efficiency, and "GB / T 21090 -2007 Color-Colorable Latex Base Paint" standard requires color stability to be a mandatory inspection item before the product leaves the factory. During the indicator inspection period, the product can only be in the state of being packaged in the production tank. The existing detection method requires more than 24 hours for a detection cycle, and Some products fail to pass the color stability test and need to be adjusted, which cannot meet the production requirements of more than a dozen orders per day for each production equipment
