Embodiment

[0013] Embodiment: a kind of preparation method of carbon nanotube adding masterbatch is characterized in that it is made of following steps:

[0014] (1) First, carry out surface modification treatment to carbon nanotubes, that is, add 4 grams of polymeric dispersants and 3 grams of titanate coupling agents to every 100 grams of carbon nanotubes, wherein the polymeric dispersants use an appropriate amount of acetone Dissolve the titanate coupling agent with an appropriate amount of petroleum ether, mix it evenly, and dry it in a drying oven to remove the solvent;

[0015] (2) Blending carbon nanotubes and polyvinyl chloride resin through surface modification, wherein the proportioning ratio of carbon nanotubes and polyvinyl chloride resin is 1:1 by mass ratio;

[0016] (3) Making the blended material into granules, that is, adding a masterbatch for the required carbon nanotubes.

[0017] A product obtained by the above preparation method with carbon nanotubes added with a ma...

Abstract

A mother material added by carbon nanotubes is prepared through modifying the surface of carbon nanotube, mixing the modified carbon nanotubes with polyvinyl chloride resin, and granulating. Said mother material can be used to prepare the carbon nanotube modified hard PVC section. Its advantage is uniform dispersion of carbon nanotubes in hard PVC, resulting in less consumption of carbon nanotubes.

Description

(1) Technical field: [0001] The invention relates to a preparation method and product of a carbon nanotube-added masterbatch for polyvinyl chloride, in particular to a preparation method and a product of a carbon nanotube-added masterbatch and a rigid polyvinyl chloride prepared by using the masterbatch. Vinyl planks. (two) background technology: [0002] Rigid polyvinyl chloride plastic has good mechanical properties, good corrosion resistance and insulation, and is cheap, so it is widely used in the chemical industry, construction industry, etc., and is also considered to be one of the good materials suitable for replacing wood. one. However, rigid polyvinyl chloride has some performance deficiencies, such as: (1) low impact strength, which is easily brittle when impacted; (2) poor heat resistance, usually only usable below 65°C. In order to overcome the shortcomings of rigid PVC, people add some substances to it to change its performance. The current more advanced meth...
