Abstract

The present invention involves a preparation method for a new type of nylon 12 composite materials. This method includes the following process steps: (1) add 20 to 40WT % of polyolefins to the melted nylon 12 monomer, disperse by stirring, (2)Diversify the 0.5 ~ 2WT % of the melted nylon 12 monomer, (3) mix the above two, add 0.5 to 2WT % cause and 0.5 ~ 2WT % to help the catalyst, and open the anion of the monomer to openRing aggregation to obtain composite materials.Compared with existing technology, the present invention has the characteristics of simple craftsmanship, short process, high efficiency, and no pollution.

Description

technical field [0001] The invention relates to a method for modifying nylon 12 with montmorillonite and polyolefin, especially the preparation and modification method of high-viscosity nylon 12. Background technique [0002] Nylon 12 (PA12) has low water absorption, good low temperature resistance, good air tightness, excellent alkali resistance and grease resistance, medium resistance to alcohols, inorganic dilute acids and aromatic hydrocarbons, good mechanical properties and electrical properties, and is a natural extinguishing material. At present, it is widely used in fuel pipes and brake pipes, optical fiber sheaths, photoelectric fiber coatings, sports equipment and food packaging in automobiles. However, due to the high cost of nylon 12 compared with the largest amount of nylon 6 and 66, its application range is seriously affected. How to reduce the cost on the basis of maintaining the mechanical properties of nylon 12 is an important problem facing the expansion...
