Embodiment 1

[0025] A color masterbatch for PP reinforcement and toughening, comprising the following components in parts by mass:

[0026]

[0027] The reinforcing modifier includes surface POE-grafted nanocellulose whiskers, and the surface POE-grafted nanocellulose whiskers are prepared by the following method:

[0028] (1) obtain alkylated nanocellulose whiskers by reacting carboxylated nanocellulose whiskers with alkyl bromide;

[0029] Dissolve the carboxylated nanocellulose whiskers (NCW) in tetrahydrofuran, and the solution is warmed up to 80°C, adding bromododecane CH3 (CH2) The mass fraction of 11Br is 60% of the nanocellulose whiskers, under sealed conditions Stirring and reacting for 4h, filtering the reacted suspension to obtain flocs, that is, obtaining alkylated nanocellulose whiskers (D-NCW); the carboxylated nanocellulose whiskers are wood pulp carboxylated nanocellulose whiskers , with an average length of 200-300nm and an average diameter of 15-30nm;

Abstract

The invention belongs to the field of PP (Polypropylene) materials and particularly relates to color master batch for reinforcing and toughening PP (Polypropylene). The color master batch comprises the following components in parts by mass: 25 to 65 parts of polypropylene, 5 to 20 parts of a toughening agent, 10 to 45 parts of a pigment, 1 to 5 parts of a coupling agent, 0.5 to 3 parts of an antioxidant and 5 to 10 parts of a reinforcing modifier. The reinforcing modifier comprises nanocellulose crystal whiskers with POE (Polyolefin Elastomer) grafted surfaces; the nanocellulose crystal whiskers with the POE grafted surfaces are obtained through the following steps: (1) taking carboxylated nanocellulose crystal whiskers and bromoalkane to react, so as to obtain alkylated nanocellulose crystal whiskers; (2) taking the alkylated nanocellulose crystal whiskers and a reaction type elastomer esterifying agent to be subjected to grafting reaction, so as to obtain a dispersion solution of thenanocellulose crystal whiskers with the POE grafted surfaces; and (3) treating the dispersion solution in step (2) by adopting a solution casting method to prepare the nanocellulose crystal whiskerswith the POE grafted surfaces. By adopting the color master batch for reinforcing and toughening the PP, the problem in the prior art that the rigid strength and tough strength of the PP are difficultto improve at the same time is solved and the prepared color master batch has good rigidity and toughness.

Description

technical field [0001] The invention belongs to the field of PP materials, and in particular relates to a color masterbatch used for strengthening and toughening PP. Background technique [0002] Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements, and can be formed into plastic products of various shapes and colors. It has been widely used in every field of modern life. There are three kinds of coloring methods for producing plastic products in the prior art: toner coloring, dyeing granule coloring and masterbatch coloring. When coloring masterbatches are used for coloring, the pigments are pretreated and evenly dispersed in the carrier resin, which greatly improves the dispersion of the pigments. Excellent performance and coloring efficiency, with the advantages of simple operation, low cost, and no pollution to the environment. [0003] As one of the five general-purpose resins, polypropylene (PP) is used in many field...
