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 a weight-volume mixing method for automotive refinish paint with accurate color masterbatch, which includes the following steps: (1) Find the weight formula of the refinish paint used; (2) According to the weight formula of the refinish paint and The measured color masterbatch specific gravity is converted to the corresponding repair paint volume formula; (3) Calculate the type of color masterbatch required and the volume and weight required for each color masterbatch; (4) Find any one of the color masterbatches according to the required color masterbatch type For the color masterbatch barrel corresponding to masterbatch A, take more than half of the volume V required by color masterbatch A 1 , weighing M 1 ; Subtract M from the weight M required by the color masterbatch 1 The resulting weight M 2 Calculate the volume V according to the specific gravity of the color masterbatch measured in step (2) 2 , take the volume as V 2 Complete the retrieving of color masterbatch A; (5) complete the retrieving of other color masterbatches in sequence according to the method in step (4); mix and stir the obtained 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...
