Problems solved by technology

[0004] However, the above method of dispersing raw materials does not actively control the dispersion of raw materials, so it is easy to destroy the spongy structure of the matting powder itself due to excessive dispersion, forming a smooth cut surface, and excessive dispersion will also change the particle size of elastic paint raw materials. If the value is too small, the extinction efficiency will decrease, which will directly lead to frequent passive changes in the paint formula, which will increase the production cost, and the tactility of the final elastic paint finished product will also be unstable, affecting the yield rate, which is not conducive to production and post-processing Promoted application of
[0005] In addition, due to the unstable touch of elastic paint products on the market, certain measures have been taken in production to improve its hand touch. The conventional method is to achieve the purpose of improving by adjusting the content of resin and special matte powder in the formula. This method requires a lot of research costs to achieve the best adjustment effect, and additional production costs. Therefore, although the production purpose of improving the touch of elastic paint can be achieved, the cost performance in practical applications is not high. need to improve

Abstract

The invention discloses a production method for improving the hand touch and dispersing technological parameter of elastic paint and a stirring device applying the production method. The type of a dispersing disc is selected, a series of dispersing technological parameters such as a dispersion speed and a dispersion time are controlled to be improved, and the elastic paint with more stable fineness, viscosity and gloss and excellent hand touch is produced. According to the production method, the dispersing technological parameter of raw material of the elastic paint is optimized, and effective production control is adopted, so that the raw material is effectively dispersed, the phenomenon that production dispersion is excessive, the gloss and hand touch of the elastic paint are stabilized, and the elastic paint is convenient for long-term storage; besides, the same technical effect of improving the hand touch of the elastic paint can be achieved without adjusting the existing product formula by improving the technological parameter, production cost is reduced while stable fineness and viscosity are given to the elastic paint product, and market value and application prospect of the elastic paint product are enhanced, so that the production method disclosed by the invention has an obvious promotion effect to the existing production.

Description

technical field [0001] The invention relates to the technical field of elastic paint production and processing technology, in particular to a method for producing dispersed process parameters for improving the hand feeling of elastic paint and a stirring device using the method. Background technique [0002] Elastic paint is a two-component matte polyester polyurethane, which has the characteristics of high elasticity, abrasion resistance and impact resistance, and has a soft touch. If it is applied to products that are often touched by hands, it will increase the added value of the product and look comfortable. And high-grade, so the elastic paint is mainly used on plastic / metal parts such as mobile phones, computers, automotive plastic components, electric tools and electrical appliances. [0003] Existing elastic paint production all selects special raw materials such as straight chain type polyester resin, and special dumb powder etc., wherein, like other pigments and fi...
