Problems solved by technology

Although the PA6 / PP alloy has many advantages, due to the volatilization of the residual monomers during the polymerization of nylon and polypropylene during the molding process, the odor is relatively large, and a compatibilizer must be added during the preparation of the PA6 / PP alloy , such as maleic anhydride grafted polypropylene, etc., these substances will release unpleasant odors to varying degrees, especially the problems of various automotive interior parts made of PA6 / PP alloys are greatly troubled

Abstract

The invention discloses a low smell, low emission, halogen-free and flame retardant PA6 / PP alloy and a preparation method thereof. The alloy comprises the following raw materials in parts by weight: 10 to 75 parts by weight of nylon 6, 10 to 75 parts of polypropylene, 10 to 30 parts of flame retardant, 1 to 5 parts of flexibilizer, 0.5 to 5 parts of hydrophobic smell adsorbing master batch, 0.1 to 1.0 part of antioxidant, and 0.2 to 1.0 part of lubricant. The preparation method comprises the following steps: weighing raw materials according to the ratio mentioned above, adding raw materials into a high speed mixing machine, mixing the raw materials for 2 to 10 minutes, adding the obtained mixture into a co-rotating parallel twin-screw extruder, and carrying out extrusion granulation. The total volatile organic compounds (TVOC) of the prepared PA6 / PP alloy are prominently reduced, and the product is not only a black product. The alloy has the characteristic of low smell, at the same time, all physical and mechanical properties of the alloy are not influenced, the alloy also has a low water absorbing rate, and the moulding and processing performance is not affected either.

Description

technical field [0001] The invention relates to a low-odor, low-emission, halogen-free flame-retardant PA6 / PP alloy and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Nylon 6 (PA6) is a general-purpose engineering plastic with excellent comprehensive properties. It has excellent mechanical properties, wear resistance, solvent resistance, and oil resistance. It is widely used in various industries. With the development of the automobile industry, my country's demand for nylon factory plastics, especially nylon alloys, is increasing. The PA6 / PP alloy prepared by blending and modifying nylon and polypropylene has excellent mechanical properties, and because of the blending of polypropylene (PP), PA6 / PP has the characteristics of high quality and low price. Although the PA6 / PP alloy has many advantages, due to the volatilization of the residual monomers during the polymerization of nylon and polypropylene durin...
