Abstract
The invention discloses high-stability, high-shading and high-adhesion environment-friendly PPA which comprises the following raw materials in percentage by mass: 17.5%-45.1% of PPA resin, 3%-12% of PA66, 1%-5% of a coloring agent, 5%-8% of a toughening agent, 0.3%-1% of an antioxidant, 0.5%-1% of a lubricant, 0.1%-1% of a coupling agent and 40%-53% of a mixture of mineral filler and glass fiber.The high-stability, high-shading and high-adhesion environment-friendly PPA can achieve complete opacity or slight opacity, and has the advantages of low warpage, low contractibility, low permeability, low water absorption, no breakage and the like; the invention further provides a preparation method of the high-stability, high-shading and high-adhesion environment-friendly PPA, and the preparation method is simple in preparation process, easy to operate and beneficial to large-scale production.
Description
technical field [0001] The invention relates to the technical field of PPA plastics, in particular to a high-stability, high-light-shielding, high-adhesion environment-friendly PPA and a preparation method thereof. Background technique [0002] Polyphthalamide (referred to as PPA) is a kind of polyamide material. Under high temperature and high humidity, the tensile strength of PPA is about 20% higher than that of PA6, and the flexural modulus is about 20% higher than that of PA. , greater hardness, can resist long-term tensile creep, and has good dimensional stability, gasoline, grease and coolant resistance, chemical resistance and other properties are also better than PA6 and PA66. PPA has low density and is easy to process and shape. It is an engineering plastic with excellent performance and wide application. It is also the fastest growing general engineering plastic in recent years. It has excellent dimensional stability, electrical insulation, creep resistance and wea...
