Problems solved by technology

[0002] Advertising paints have been widely used, yet, the performance of the advertising paints in the prior art in terms of tinting strength, lightness and crack resistance is still unsatisfactory, and needs to be further improved
In addition, in the prior art, natural peach gum is usually used to synthesize glue so as to further produce advertising paint. Because natural peach gum is very dark in color and smells bad, the resulting advertising paint has a heavy smell and is not bright and beautiful.
In addition, the advertising paints of the prior art use phenol or formaldehyde as preservatives, and these substances will cause certain damage to the environment

Embodiment 1

[0053] Heat the natural peach gum to 50-60°C in the reaction kettle, control the pressure at 1-1.5 atmospheres, stir and dissolve for 1-1.5 hours. Put the above dissolved matter in a storage tank for more than 10 hours, then use a pump to pump the supernatant to another storage tank, add decolorizer and deodorant and stir for 1 hour, then let it stand, and draw the supernatant again , so repeated three times to obtain a nearly colorless peach gum solution. Distill at 60° C. and a pressure of minus 3 atmospheres until it becomes a solid block of peach gum. The solid block is dried in an oven until the water content reaches 4-7%, and then ground and pulverized so that the fineness reaches 10-20um and sealed for storage.

[0054] Add 20 parts by weight of peach gum processed as above to 70 parts by weight of water, heat and stir at 50° C. until the peach gum is completely dissolved. Then, cool to room temperature, add 6 parts by weight of glycerin, 4 parts by weight of ethylene...

Embodiment 2

[0057] Add 25 parts by weight of peach gum processed in the same manner as described in Example 1 into 60 parts by weight of water, and heat and stir at 90° C. until the peach gum is completely dissolved. Then, cool to room temperature, add 4 parts by weight of glycerin, 10 parts by weight of ethylene glycol and 8 parts by weight of 1,2-benzisothiazolin-3-one, and continue to stir for 25 minutes, thus obtaining a glue liquid.

[0058] In the batching tank, the above-obtained glue solution, 10 parts by weight of phthalocyanine green (product of model 5319 purchased from Hangzhou Pigment Company), and 75 parts by weight of aluminum hydroxide were mixed at 90° C. until completely wetted. Then, the resulting homogeneous mixture was ground 3-5 times with a three-roll mill to obtain the desired pigment. The thickness and fineness of the obtained pigment were measured with a scraper fineness meter and a coating thickness instrument, and the average fineness was 38 microns, and the av...

Embodiment 3

[0060] Add 15 parts by weight of peach gum processed in the same manner as described in Example 1 into 80 parts by weight of water, and heat and stir at 75° C. until the peach gum is completely dissolved. Then, cool to room temperature, add 10 parts by weight of glycerin, 8 parts by weight of ethylene glycol and 5 parts by weight of 1,2-benzisothiazolin-3-one, and continue stirring for 20 minutes, thus obtaining a glue liquid.

[0061] In the batching tank, stir and mix the above-obtained glue liquid, 6 parts by weight of red powder (purchased from Hangzhou Pigment Company's 3132 model product), and 50 parts by weight of calcium carbonate at 60° C. until completely wetted. Then, the resulting homogeneous mixture was ground 3-5 times with a three-roll mill to obtain the desired pigment. The thickness and fineness of the obtained pigment were measured with a scraper fineness meter and a coating thickness instrument, and the average fineness was 30 microns, and the average thickn...

Abstract

A composite for pigment, pigment made from and its production are disclosed. The composite consists of peach glue 10-30 proportion, glycerol 4-15 proportion, water 60-85 proportion, ethylene glycol 4-10 proportion, filler 45-80 proportion, colorant 2-10 proportion and antiseptics 2-8 proportion. It's inodorous, has excellent coloring and cracking performances, brightness and friendly environment.

Description

technical field [0001] The invention relates to a composition for pigments, a pigment and a preparation method thereof, in particular to a composition for an advertisement painting pigment, an advertisement painting pigment and a preparation method thereof. Background technique [0002] Advertising paints have been widely used. However, the performances of the advertising paints in the prior art are still unsatisfactory in terms of tinting strength, lightness and crack resistance, and need to be further improved. In addition, in the prior art, natural peach gum is usually used to synthesize glue so as to further produce advertising paint. Because natural peach gum is very dark in color and smelly, the resulting advertising paint has a heavy smell and is not bright and beautiful. In addition, the advertising paints in the prior art use phenol or formaldehyde as preservatives, and these substances will cause certain damage to the environment. Contents of the invention [00...
