Problems solved by technology

The main reason is that the measurement of volume is inaccurate, and the equipment after the launch cannot meet the demand. The first-class foreign manufacturers have tried to solve this problem for a long time. It is generally believed that automotive paint can only be measured by weight ratio

Embodiment Construction

[0033] For the case where the specific gravity of the color masterbatch is stable or the demand for the color masterbatch is relatively small, the volume method can be used to achieve accurate color masterbatch. The method of using volume ratio color matching is as follows;

[0034] The volumetric color matching method of automobile refinish paint comprises the following steps:

[0035] (1) Find out the ID card of the car with the color number printed on the repaired body, find out the color code of the car or compare the code of the color card that is close to it, and use the reader or computer color matching system to find out the weight formula of the repair paint used ; Or use a spectrophotometer to detect the complete surface of the car body coating to be repaired, and output the weight formula of the repair paint through calculation;

[0036] (2) Calculate the volume formula of the corresponding repair paint according to the weight formula of the repair paint and the me...

Abstract

In order to solve the technical prejudice, the present invention provides an automobile refinishing paint weight-volume mixed toning method with accurate color masterbatch matching. The method comprises the following steps: (1) finding a refinishing paint weight formula; (2) converting a corresponding refinishing volume formula according to the refinishing paint weight formula and the measured color masterbatch proportion; (3) calculating the type of the required color masterbatch as well as the required volume and weight for each color masterbatch; (4) finding a color masterbatch barrel corresponding to any one of the color masterbatch A according to the desired type of masterbatch, and taking a large part V1of the required volume V for the color masterbatch A, and weighing M1; subtracting M1 by the weight M2 required by the color masterbatch to obtain the weight M2, converting the weight M to the volume V2 according to the color masterbatch proportion measured in the step (2), and taking the color masterbatch A having the volume of V2 to complete the material taking of the color masterbatch A; and (5) according to the method in the step (4), sequentially taking the other color masterbatch; and mixing and stirring the acquired color masterbatch.

Description

technical field [0001] The invention belongs to the field of automatic deployment of automobile refinish paint, and in particular relates to a method for mixing color by weight and volume of automobile refinish paint. Background technique [0002] Damaged parts of the car paint need to be re-sprayed with car refinish paint. Different car refinish paints require different masterbatches. In order to meet the needs of different cars, there are many kinds of color masterbatches required for car paint color matching, about 50 to 90 kinds, far more than the types of latex paint. There are so many color master barrels that need to be equipped on the auto refinish paint automatic coloring machine, which requires a lot of space. For any kind of automatic color matching of automotive refinish paint, it is necessary to accurately move the paint mixing cup to all the required color master barrels, which requires the automatic color mixing machine to have a precise and complex transmis...
