Embodiment 1

[0039] A PVC resin with high color stability, adding 5% color masterbatch of matrix resin weight to PVC matrix resin,

[0040] The color masterbatch is made of the following raw materials by weight: 13 parts of pigment, 1.1 parts of dispersant, 32 parts of PVC resin, 0.65 parts of antioxidant, and 18 parts of filler;

[0041] The filler is prepared using the following method:

[0042] (1) Dry the diatomaceous earth;

[0043] (2) Soak the montmorillonite in a nitric acid solution with a mass fraction of 15% for 35 minutes, use ultrasonic vibration treatment during the soaking process, and then dry it;

[0044] (3) Take 10 parts of polyethylene glycol, 0.3 parts of expanded graphite, 1.5 parts of glass fiber, and 15 parts of water by weight, and stir at 40°C for 1.2 hours to obtain a mixed solution;

[0045] (4) Mix the diatomite prepared in step (1), the montmorillonite prepared in step (2), and the mixed solution obtained in step (3) in a ratio of 4:1.2:3 by weight, at 550r / ...

Embodiment 2

[0063] Compared with Example 1, the color masterbatch is made of the following raw materials by weight: 15 parts of pigment, 1.3 parts of dispersant, 35 parts of PVC resin, 0.7 parts of antioxidant, 20 parts of filler, and other processing methods are the same as in Example 1 .

Embodiment 3

[0065] The glass fibers are not modified, and the others are the same as in Example 1.

Abstract

The invention relates to high-color-stability PVC (polyvinyl chloride) resin. A color master batch which is 2-5% of a matrix resin weight is added to PVC matrix resin. According to the resin providedby the invention, through adding the specially prepared color master batch, a color of the resin added with the color master batch has good temperature resistance.

Description

technical field [0001] The invention relates to the field of novel plastic pigments, in particular to a PVC resin with high color stability. Background technique [0002] PVC used to be the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. In many fields, it is necessary to color PVC before use. Usually, the color of PVC resin is improved by color masterbatch. Color masterbatch is a plastic colorant formed by a high proportion of pigment or additive and thermoplastic resin, which is well dispersed. The selected resin has a good wetting and dispersing effect on the colorant, and has good compatibility with the material to be colored. [0003] There are high requirements on the stability and processing performance of the masterbatch during use...
