Example Embodiment

[0028] The present invention will be further illustrated by specific examples below.

[0029] The composition ratio and physical and mechanical properties of each embodiment of the present invention are shown in Table 1 and Table 2. Among them, Examples 1-5 are the mechanical properties of nano calcium carbonate / polypropylene prepared without the reactive monomer masterbatch, and the reactive monomer used in Examples 6-17 is acrylic acid. The stabilizer used in each example is polypropylene universal antioxidant 1010.

[0030] The preparation method of each embodiment is as follows:

[0031] 1) Mixing: Add the raw materials of each component to the high-speed mixer according to the aforementioned ratio, and mix at room temperature for 1 minute at high speed;

[0032] 2) Melt and extrude the above-mentioned mixture with a twin-screw extruder at 190-220°C, rotating speed 300-350rpm;

[0033] 3) The extrudate is cooled by water and pelletized to obtain the required reactive monomer m...

Abstract

The present invention relates to a reactive monomer modified nano calcium carbonate/polypropylene mother material and its production method. Said mother material is formed from polypropylene base body, nano calcium carbonate filling material, reactive monomer (including maleic anhydride, acrylic acid and its esters and styrene) and universal stabilizing agent D of PP material. Its preparation method includes the steps of uniformly mixing by using high-speed mixing machine and extruding by means of twin screw extruder machine. Said invention can raise the mechanical property of nano calcium carbonate filled polypropylene material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a reactive monomer modified nanometer calcium carbonate / polypropylene masterbatch and a manufacturing method thereof. Background technique [0002] Transforming traditional polymer materials with nanotechnology and materials is a hot research topic at home and abroad. Nano-calcium carbonate is currently the nano-material with the largest output and the lowest price. Micron-sized calcium carbonate is widely used in polypropylene. Due to the poor compatibility between calcium carbonate and polypropylene, the addition of high dosage of calcium carbonate usually reduces the mechanical properties of polypropylene materials. The nano-calcium carbonate will produce more interfaces in polypropylene. If the nano-calcium carbonate can be fully dispersed and the interfacial interaction is strengthened, the nano-calcium carbonate will lead to further improvement of the...
