Problems solved by technology

In the 1990s, my country developed a "hydrogen fluoride indicator paint", but compared with foreign products, there are problems such as inconspicuous discoloration, long discoloration time, irreversible discoloration (only one-time use), and the application is greatly limited.
At present, the acid warning paint used in China basically relies on imports, and there are problems such as high price and long delivery cycle.

Embodiment Construction

[0016] Technical scheme of the present invention is as follows:

[0017] A warning paint that changes color in case of acid, comprising the following components in parts by mass:

[0018] 50-100 parts of strong acid-resistant resin, 1-30 parts of special discoloration agent A, 0.5-5 parts of auxiliary discoloration component, 0-20 parts of filler, 0-20 parts of auxiliary agent, 0-300 parts of solvent;

[0019] Described special discoloration agent A has following structural characteristics:

[0020]

[0021] Among them: R' is a variety of organic groups that act as bridges to connect the benzene ring to the silicon atom; it is further preferably an alkylene group, more preferably a C1-C8 alkylene group, preferably a methylene group, an ethylene group or propylene;

[0022] R" is a variety of organic groups that can leave with the HOR" structure; more preferably alkyl or aryl, more preferably C1-C8 alkyl or phenyl, preferably methyl, ethyl, isopropyl, tertiary butyl or ph...

Abstract

The present invention relates to a color-changing warning paint in case of acid and a preparation method thereof. 0-20 parts, 0-20 parts of additives, 0-300 parts of solvents. The acid-encounter warning paint for strong acid, obvious and rapid discoloration and reversible discoloration of the present invention. Using single-component strong acid-resistant resin as the base resin, adding special color-changing agent A, auxiliary color-changing components, pigments and fillers, etc., the acid-encountered warning paint has the characteristics of obvious color change, rapid color change, reversible color change, and good matching. Suitable for manufacturing, storage, transportation and device surfaces where strong acids are used. The market demand prospects of petroleum alkylation, fluorine chemical industry, ore flotation, pulp and paper industry, semiconductor industry and other manufacturing industries are good.

Description

technical field [0001] The invention relates to a color-changing warning paint in case of acid, which belongs to the field of comprehensive utilization of chemical products. Background technique [0002] Concentrated sulfuric acid, hydrofluoric acid, nitric acid, hydrochloric acid and other strong acids are widely used in chemical production such as petroleum alkylation, fluorine chemical industry, ore flotation, pulp and paper industry, semiconductor industry, etc., and have made great contributions to promoting the development of the national economy. huge contribution. At present, there are two traditional alkylation processes in the petrochemical industry, namely hydrofluoric acid method and sulfuric acid method. [0003] The sulfuric acid method uses sulfuric acid as a catalyst to synthesize industrial isooctane (ie, alkylated oil) from isobutane and butene. The prepared alkylate is a mixture of isoparaffins, not only has good anti-knock performance, the octane number...
