Description

A kind of environmentally friendly allochroic paint with alarm function and preparation method thereof
Technology neighborhood
The present invention relates to paint field, and in particular to a kind of environmentally friendly allochroic paint and its preparation side with alarm function Method.
Background technology
As national laws regulation is to VOC (VOC) limitation and the control of environmental pollution, develop ring Border close friend's coating has become the focus of coating research field.
As inside and outside wall emulsion paint demand constantly rises these years, emulsion paint field high speed development.Traditional interior wall is applied Material corrosion resistance, wearability, good luster, adhesive force are strong, but conventional interior wall coating be usually with organic solvent as dispersant, and The big multipair human body of organic solvent has certain harm.
Substantial amounts of harmful acidity or alkaline matter are had in the production processes such as some chemical plant, metallurgical works Generation, the workpeople for working in this environment can virtually be persecuted by bronsted lowry acids and bases bronsted lowry, influence healthy, energy and chronognosis Examine, and take effective measures avoid soda acid endanger it is particularly important.
The people of multiple demand with to(for) interior wall coating color, some colour-wash applications and give birth to.Have photochromic Coating and temperature-control discoloring coating, these allochroic paints are widely used in the aspects such as various jewelrys, clothes, toy, printing.And by The application of the allochroic paint of soda acid control is actually rare.A kind of crossed in alkali environment in peracid with alarm function if can provide The coating that can change colour, it is necessary to improve the measure that people protect to the consciousness of clean environment and positive egodefense.
The content of the invention
It is an object of the invention to provide a kind of environmentally friendly allochroic paint with alarm function and preparation method thereof, the discoloration Coating can with environment peracid cross the change of alkali and show different colours, neutral environment color fade in water white transparency, is come with this It is effective to alert persons the change of working environment soda acid, safeguard measure is taken, make one to be maintained at one to healthy harmless Ambient condition.This environmentally friendly allochroic paint formula is simple, with low cost, it is easy to mass produce
A kind of environmentally friendly allochroic paint with alarm function that the present invention is provided, it is characterised in that component is counted by weight Including：Polyurethane resin material 10-30, ethanol 20-40, antishrinking agent 0.01-0.03, triphenylmethane dye or fluoran dyes 0.03-0.2。
Described triphenylmethane dye is：Adjacent diformazan phenolphthalein, thymolphthalein；Fluoran dyes are：3- diethylin -6- Methyl -7- anilino fluoranes, 9- (2- methylphenylaminos) benzo fluorane.
Appropriate preservative can also be added in described environmentally friendly allochroic paint component, appropriate amount of essence can also be also added, Such as cinnamic acid.
The preparation method of environmental protection allochroic paint of the invention, comprises the following steps：
(1) to take material standby for the component proportion as described in claim 1；
(2) triphenylmethane dye or fluoran dyes are dissolved in absolute ethyl alcohol and are sufficiently stirred for dissolving；
(3) by material obtained in poly- amino resins addition step (2), after addition is finished, it is sufficiently stirred for mixing；
(4) in antishrinking agent being added into mixed solution obtained in step (3), stirring, you can obtain with alarm function Environmentally friendly allochroic paint.
The advantages of the present invention compared with modern technologies：
(1) coating of the invention has alarm function, and soda acid change can be effectively crossed in indicative for environments, is capable of achieving to work The monitoring of Environmental security health.
(2) coating of the present invention is in itself water white transparency, is presented red and blue in acid environment, is presented in alkaline environment black Color and purple, neutral environment color fade.
(3) present invention uses ethanol as solvent, can significantly reduce indoor poisonous VOC (volatile organic matter) and contain Amount.
(4) environmentally friendly allochroic paint of the invention has anticorrosive well and anti-contracility energy, and with fragrance.
(5) inventive formulation is simple, with low cost, it is easy to a large amount of productions.
