PP (polypropylene) nano plastic and preparation method thereof

Abstract

The invention discloses a PP (polypropylene) nano plastic and a preparation method thereof. The PP nano plastic is prepared from nano organic montmorillonite, octadecyltrimethyl ammonium bromide, dimethyl polysiloxane PP grafted maleic anhydride, nano silicon dioxide, nano calcium carbonate, maleic anhydride grafted polyethylene, nano mullite, a silane coupling agent KH-570, nano aluminum oxide and nano calcium oxide. The product has high strength, the tensile strength is 45-65 MPa, and the Rockwell hardness is 120-140. The impact strength is 80-100 KJ / m<2>, and the Vicat softening point is 165-185 DEG C. The shrinkage is 0.3-0.7%, the bending strength is 55-75 MPa, and the bending modulus is 2500-4500 MPa. The melt flow index is 11.3-11.7 g / 10 minutes, and the elongation at break is 45-85%. The PP nano plastic has the advantages of excellent frictional wear and low cost, is simple to operate, and can be widely produced and continuously substituted for the existing materials.

Description

technical field [0001] The application belongs to the field of nano-plastic materials, and in particular relates to a PP nano-plastic and a preparation method thereof. Background technique [0002] Nanomaterials is a completely new scientific field that has just emerged in recent years. It involves knowledge in many fields such as aggregate physics, chemistry, materials, and biology. The core content of "nanotechnology" is how to solve the problem of agglomeration of nanoparticles. Since nanoparticles themselves are very easy to agglomerate, it is very difficult to obtain single dispersed nanoparticles. How to make nanoparticles evenly disperse into the matrix is ​​"nanotechnology". key technologies. [0003] At present, from the analysis of the application research reports of "nanotechnology", there are two methods that can be industrialized: 1. Nano intercalation technology, that is, n-MMT processed by intercalation is made with a certain degree of compactness and a certa...
