Description
Technical field
The present invention relates to pigment technology fields, in particular to a kind of food packaging environmental protection pigment purple and preparation
Method.
Background technique
Pigment, using very extensive coloring material, which are mainly applied to coating, printing and dyeing, plastic products, is made as a kind of
The industries such as paper, rubber product and ceramics, with the fast development of downstream industry, the demand to pigment constantly expands.
Traditional pigment violet is applied more in the industry, and with the development of technology, more and more pigment violets are in food
There has also been certain applications in packaging.In food packaging, pigment in addition to need to reach gloss is bright-coloured and the requirement of strong coloring force it
Outside, it is also necessary to guarantee the high requirement of heatproof, and even more important in environmental-protecting performance, and current pigment violet also has in these areas
Being weak can't achieve the purpose that take into account in other words.
Summary of the invention
In consideration of it, the present invention provides a kind of food packaging environmental protection pigment purple and preparation methods, it is intended to solve existing
The bad problem of pigment violet stability in technology.
For this purpose, the present invention provides a kind of food packaging environmental protection pigment is purple comprising the group of following weight percent
Point:
Further, above-mentioned food packaging environmental protection pigment purple includes following components in percentage by weight: alkalescence purple 21-
24%；Glacial acetic acid 2-3%；Disodium hydrogen phosphate 5-6%；Sodium tungstate 21-23%；Sodium molybdate 16-17%；Pigment auxiliary agent 1-2%；
Hydrochloric acid 21-24%；Rosin 3-4%；Liquid alkaline 2-3%.
Further, above-mentioned food packaging environmental protection pigment purple includes following components in percentage by weight: alkalescence purple
23%；Glacial acetic acid 2%；Disodium hydrogen phosphate 5%；Sodium tungstate 22%；Sodium molybdate 16%；Pigment auxiliary agent 2%；Hydrochloric acid 23%；Rosin
4%；Liquid alkaline 3%.
Further, above-mentioned pigment auxiliary agent includes the first pigment auxiliary agent and the second pigment auxiliary agent, and the ratio of the two is 6:4.
A kind of a kind of preparation method of food packaging environmental protection pigment purple as described above comprising following steps:
1) dissolving alkalescence purple in 80-90 DEG C of water；
2) sodium tungstate, sodium molybdate and disodium hydrogen phosphate are dissolved；
3) solution dissolved in step 2) is added in the alkalescence purple dissolved in step 1)；
4) reaction is completed, and material is successively rinsed, dries and crushed.
Further, above-mentioned pigment auxiliary agent includes the first pigment auxiliary agent and the second pigment auxiliary agent, and the ratio of the two is 6:4.
Further, above-mentioned steps 1) in, water temperature is 85 DEG C.
Food packaging environmental protection pigment purple provided by the present invention and preparation method, by described with the when side of preparation
Method, so that obtained pigment violet has the advantages that the high and low aromatic amine of heatproof and low heavy metal compared to the prior art, in the feature of environmental protection
Can on more preferably.
Specific embodiment
The exemplary embodiment of the disclosure is described in more detail below.Although showing the exemplary implementation of the disclosure
Example, it being understood, however, that may be realized in various forms the disclosure and should not be limited by the embodiments set forth herein.On the contrary,
These embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can communicate completely to the scope of the present disclosure
Those skilled in the art.
The following are a kind of food packaging environmental protection pigment provided in an embodiment of the present invention is purple and preparation method.The food packet
Dress is obtained with environmental protection pigment purple by following proportion, and total weight is in terms of 500KG.
