Problems solved by technology

[0003] The purpose of the present invention is to provide a modified plastic color masterbatch and its preparation method. The carrier resin of the color masterbatch, the colored polyacrylamide resin, is directly polymerized on the surface of the pigment and filler to form a coating on the surface of the pigment and filler. Coating layer, the coating layer is a polymer of maleic anhydride and incompletely saponified oil. The polymer contains unsaturated olefinic bonds, which can undergo polymerization reactions and polymerize with acrylamide and trifluoroethyl methacrylate, so that The surface of the pigments and fillers is grafted with amino groups and a large amount of fluorine elements. Through the cross-linking of glutaraldehyde between amino groups and soybean ol

Embodiment 1

[0034] The specific preparation process of colored polyacrylamide resin is as follows:

[0035] Step 1, take 1kg of the mixture of peanut oil and soybean oil, add 350g of sodium hydroxide solution with a mass fraction of 10% to it, raise the temperature to 80°C and stir for 2 hours, pour the product into a separatory funnel and let it stand for 30 minutes to separate layers, the lower layer It is the water phase after saponification, and the upper layer is oil that has not been completely saponified, and the upper layer is obtained by layering;

[0036] Step 2, dissolve 100g of pigments and fillers in 900mL of water, then add 62g of maleic anhydride, 10g of p-toluenesulfonic acid and 85mL of SP-80 into it, stir and mix evenly;

[0037] Step 3: After heating up to 75°C, add 380 mL of the upper layer solution prepared in Step 1 dropwise to the mixed solution in Step 2, stir while adding, and react at a constant temperature for 1 hour after the addition is complete, then filter a...

Abstract

The invention discloses a modified plastic color masterbatch comprising the following components by weight: 63-69 parts of colored polyacrylamide resin, 21-24 parts of soybean oligopeptide, 12-15 parts of glutaraldehyde, 100 parts of water and 3-7 parts of a plasticizer. The carrier resin colored polyacrylamide resin of the color masterbatch is directly polymerized on the surface of a pigment filler to form a coating layer on the surface of the pigment filler, the coating layer is a polymer of maleic anhydride and incompletely saponified fat, the polymer contains an unsaturated olefin bond which is capable of undergoing polymerization and polymerizing with acrylamide and trifluoroethyl methacrylate, so that the surface of the pigment filler is grafted with amino groups and a large amount of fluorine, by glutaraldehyde cross-linking action between the amino groups and the soybean oligopeptide, the center of the prepared colored polyacrylamide resin is the pigment filler, and the pigmentfiller is directly and uniformly dispersed and coated in the carrier resin colored polyacrylamide resin, so that the prepared color masterbatch needs no dispersant to achieve even color distribution.

Description

technical field [0001] The invention belongs to the field of color masterbatch, and relates to a modified plastic color masterbatch and a preparation method thereof. Background technique [0002] The method of plastic coloring can be divided into body coloring method and coloring preparation method, but the dispersibility of the pigment is poor, and the coloring effect of the dust is not ideal. Therefore, the problem of pigment dispersibility is effectively solved by the masterbatch coloring method, in which the masterbatch is passed Add pigments, dispersants and additives to the carrier resin, and then prepare by melting and mixing, so that the prepared color masterbatch has the color of the pigment itself, but when the pigment is directly mixed with the carrier resin by mechanical stirring, although the dispersant is added, However, the mixed color material still cannot fully achieve a uniform effect. At the same time, the prepared color masterbatch itself has a certain di...
