Embodiment Construction
[0010] The composition of the wear-resistant modified PA6T nylon material provided by the present invention includes but is not limited to 6 kinds as shown in Table 1 below;
[0011] The wear-resistant modified PA6T nylon material provided by the present invention can be carried out according to the following processes in the production process:
[0012] Mix the coupling agent and wear-resistant filler in proportion at 50 °C for 10 minutes and then place it at room temperature for 8 hours; mix PA6T with pretreated wear-resistant filler, antioxidant, heat stabilizer and other additives in a high-temperature mixer in proportion Pre-mixing at medium and low speed for 1 minute, and then mixing at medium speed for 5 minutes; feed the mixed raw materials from the main feed and glass fiber from the side in proportion, knead and extrude through a twin-screw extruder, and granulate with water-cooled strands. After vibration screening and dehydration, wear-resistant modified PA6T nylon ...

The invention discloses a high-wear-resistance modified high polymer material, and particularly relates to a high-wear-resistance modified PA6T composite material. The material is composed of the following components in percentage by weight: 65%-80% of PA6T material, 15%-35% of glass fiber, 1%-10% of wear-resistant filler, 0.5%-1.5% of antioxidant, 0.5%-1.5% of heat stabilizer, 0.5%-1.5% of coupling agent and 0.5%-1.5% of other auxiliaries. The components are subjected to twin-screw extrusion, mixing and granulation, so that the filling modified high-wear-resistance PA6T composite material isobtained. According to the invention, the defects of poor toughness and insufficient wear resistance of the PA6T material are overcome, and through filling modification, the friction coefficient of the material is effectively reduced while the strength and toughness of the material are enhanced, and the wear resistance is improved. The PA6T composite material provided by the invention has important application value and product competitiveness in the fields of mechanical manufacturing, electronics and electricians, automobiles and the like.
Description
technical field [0001] The invention relates to the technical field of a wear-resistant polymer material, more specifically, a wear-resistant modified PA6T nylon material. Background technique [0002] Nylon is a widely used engineering plastic and plays an important role in national economic construction. As a new type of special engineering plastic that has attracted much attention in recent years, PA6T is widely used in machinery manufacturing, electronics, automobiles and other industrial manufacturing fields due to its high strength, high temperature resistance, good insulation performance, and stable chemical properties. PA6T materials with excellent performance are mainly monopolized by foreign chemical companies. At present, there is still a certain gap between domestically produced PA6T materials and foreign countries in terms of comprehensive performance, such as: difficult processing, poor toughness, and insufficient wear resistance. Therefore, it is necessary to...
