Abstract
The invention discloses an aqueous color-variable treatment agent. The aqueous color-variable treatment agent comprises rubber, acrylic resin, polyurethane resin or polyester resin, and also comprises vinyl ether, one or more indicators and a fixing agent. The one or more indicators are selected from methyl orange, methyl red, bromophenol blue, phenolphthalein, purple litmus reagent, bromocresol green, neutral red, thymolsulfonphthalein, thymolphthalein and alizarin yellow. The one or more indicators are sensitive to a pH value. The ether, the petroleum resin, isocyanate, the epoxy resin and the fixing agent anchor the indicator and provide a color change environment. The product treated by the aqueous color-variable treatment agent has high pH sensitivity and can change its color in an acid/base environment. The aqueous color-variable treatment agent has good adhesion to a plurality of cloths and porous materials, produces small influence on the materials, does not contain any organic solvent, does not damage a human body and can be widely used for the daily life.
Description
Technical field
The present invention relates to chemical field, relate in particular to acid base indicator, particularly a kind of water-based variable color treating agent.
Background technology:
Acid base indicator is widely used in the laboratory.But because use inconvenience, so seldom be applied in the daily life.For example: baby' diaper has very strong water absorptivity, only is difficult to find whether contain urine in the baby' diaper with naked eyes.Drip acid base indicator on baby' diaper, can judge whether to contain urine according to change color, still, the inconvenient acid base indicator that utilizes at any time detects just in use baby' diaper in the daily life.
Summary of the invention:
Technical matters to be solved by this invention provides a kind of water-based variable color treating agent, and described this water-based variable color treating agent will solve the technical matters that acid base indicator in the prior art is difficult to be applied to daily life.
This water-based variable color treating agent of the present invention contains rubber or acryl resin or urethane resin or vibrin, also contains vinyl ether, indicator and fixing agent, and the weight portion of above-mentioned substance is as follows,
100 parts in rubber or acryl resin or urethane resin or vibrin,
45.0～55.0 parts of vinyl ether,
1.0～5.0 parts of indicator,
0.01～0.03 part of fixing agent.
Further, also contain petroleum resin, the weight portion of described petroleum resin is 1～10.0 part.
Further, also contain isocyanates, the weight portion of described isocyanates is 1～10.0 part.
Further, also contain epoxy resin, the weight portion of described epoxy resin is 1～10.0 part.
Further, described indicator is selected from one or more in methyl orange, methyl red, bromophenol blue, phenolphthalein, purple reindeer moss, bromcresol green, dimethyl diaminophenazine chloride, thymol blue, thymolphthalein, the alizarin yellow.
Further, described fixing agent can adopt G4502 type material of the prior art.
Further, described fixing agent is the sulfonation isocyanates.
Principle of work of the present invention is: indicator is to the soda acid sensitivity, and ethers, petroleum resin, isocyanates, epoxy resin and fixing agent carry out anchoring to indicator, and is indicator creation changeable colour environment.The product that utilizes the present invention to handle has hypersensitivity to soda acid, has obvious change color in acid or alkali environment.
The present invention compares with prior art, and its effect is actively with tangible.Water-based variable color treating agent of the present invention has hypersensitivity to soda acid, and the product of handling has obvious change color in soda acid.The present invention has good tack in multiple cloth and porosint, minimum to the performance impact of material own, does not contain any organic solvent, and human body is not had injury, can be widely used in the daily life.
