Problems solved by technology

[0007] Seen from above-mentioned open document, at present finger (water powder) pigment mainly adopts base materials such as starch, glycerin, surfactant and colorant preparation, but except that document 1 report can be dipped in the pigment that is dipped in clothes with water and wash off, other document does not have mentions that this characteristic
Document 1 also has the problem that the product is prone to stratification and precipitation, and insoluble matter is produced during painting

Embodiment 1

[0031] First prepare modified starch, the preparation method is: adjust 30kg of starch with water to a starch slurry with a concentration of 35-40%, put it into the reactor, add etherification agent: propylene oxide or chloroacetic acid, and the addition amount is 1% of dry starch. %, under the conditions of 40-70°C and the presence of an alkali catalyst, the alkali catalyst is sodium hydroxide or calcium hydroxide, the amount added is 3% of the absolute dry starch, the etherification reaction is 1-2 hours, and then the esterification agent is added, The esterification agent is 10% acetic acid, the addition amount is 5% of the absolute dry starch, and it is esterified at 40-70 DEG C for 1 hour to obtain modified starch. Then put 50kg of water into the reactor, start stirring, and start to heat up. When the temperature rises to 60-80°C, keep the mixture of the above-mentioned modified starch and 3kg of glycerol at 60-80°C according to the above weight ratio. Continue to stir fo...

[0033]First prepare modified starch, the preparation method is: adjust 20kg of starch with water to a starch slurry with a concentration of 35-40%, put it into the reactor, add etherifying agent: propylene oxide or chloroacetic acid, and the addition amount is 1% of dry starch. -5%, under the conditions of 40-70°C and the presence of an alkali catalyst, the alkali catalyst is sodium hydroxide or calcium hydroxide, the amount added is 2-10% of the absolute dry starch, etherification reaction is 1.5 hours, and then esterification The esterification agent is 10-30% acetic acid, the addition amount is 2-10% of dry starch, and it is esterified at 40-70°C for 1.5 hours to obtain modified starch. Then put 40kg of water into the reactor, start stirring, and start to heat up. When the temperature rises to 60-80°C, keep the mixture of the above-mentioned modified starch and 5kg of glycerin according to the above weight ratio, and keep the temperature at 60-80°C. Continue to stir for 10-...

Embodiment 3

[0035] First prepare modified starch. The preparation method is: adjust 10kg of starch with water to a starch slurry with a concentration of 35-40%, put it into the reactor, add etherification agent: propylene oxide or chloroacetic acid, and the addition amount is 5% of dry starch. %, under the conditions of 40-70°C and the presence of an alkali catalyst, the alkali catalyst is sodium hydroxide or calcium hydroxide, the amount added is 9% of the absolute dry starch, etherification reaction is carried out for 2 hours, and then esterification agent is added to esterify The agent is 10-30% acetic acid, the addition amount is 9% of dry starch, and it is esterified at 50-70°C for 2 hours to obtain modified starch. Then put 30kg of water into the reactor, start stirring, and start to heat up. When the temperature rises to 60-80°C, keep the mixture of the above-mentioned modified starch and 4kg of glycerin according to the above weight ratio, and keep the temperature at 60-80°C. Cont...

Abstract

The invention discloses a finger painting pigment and a method for producing the same. The finger painting pigment consists of pigment base slurry and coloring matters; the compositions of the pigment base slurry comprise glycerin, modified starch and casson; a product has no phenomenon of delamination, has excellent appearance effect; simultaneously, in the painting process, the pigment is quite fluent and has no granular sensation, bright and beautiful color and strong flexural strength, also has obvious advantages in adhesion fastness and color saturation, is safe and innoxious and is easy to elute when stuck on clothes.

Description

technical field [0001] The present invention relates to a kind of pigment, especially a kind of finger paint and its production method. Background technique [0002] The pigments seen at present are divided into oil paints, watercolor paints, traditional Chinese painting paints, finger paints, etc. according to the type of painting. The composition of paints is an important basis for the beautiful enjoyment of paintings. Oil paints, watercolor paints, and traditional Chinese paints are mainly made with brushes and do not directly contact the skin, so the ingredients of the base and color materials are not very particular, and some may use harmful minerals. However, finger paint must be dipped in paint by hand, and then painted on canvas, paper or other objects. It is safe and easy to wash off when it is stained with clothes. Because finger painting is not only the creation of art works by painters or students of the Academy of Fine Arts, many children also enter the stage ...
