Abstract

The invention relates to the field of macromolecular materials, in particular to a high-heat-resistance high-impact PA / ABS alloy material. The high-heat-resistance high-impact PA / ABS alloy material consists of the following components in parts by weight: 5 to 30 parts of ABS resin, 40 to 70 parts of PA resin, 3 to 10 parts of a compatilizer, 5 to 20 parts of a toughening agent, 0.1 to 1 part of an antioxidant, 0.1 to 0.5 part of a lubricating agent, 0.1 to 2 parts of an ultraviolet light absorber and 0.1 to 2 parts of a light stabilizer. According to the high-heat-resistance high-impact PA / ABS alloy material, the proper compatilizer is selected to guarantee the compatibility of the PA / ABS alloy; the proper toughening agent is selected to improve the heat resistance of the material on the premise of guaranteeing the impact toughness of the material; proper PA and ABS raw materials and proportion thereof are selective to guarantee high impact and high heat resistance of the material; the Vicat temperature of high-heat-resistance alloy material can reach 140 DEG C, the notch impact toughness is 400 J / m, and the high-heat-resistance high-impact PA / ABS alloy material can be applied to the fields of electronic and electrical appliances, automobiles and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PA / ABS alloy material with high heat resistance and high impact. Background technique [0002] Polyamide (PA) has developed into one of the most important varieties of engineering plastics due to its excellent mechanical strength, wear resistance, self-lubricating properties and corrosion resistance. However, it has disadvantages such as high water absorption, poor dimensional stability, low temperature and poor dry impact, which greatly limit its application in some fields. By blending and modifying ABS and PA, a PA / ABS alloy with both advantages can be obtained, and at the same time, unique advantages that neither of them have can be obtained, such as: a unique matte effect, which is not available in some other materials ; It has heat resistance no less than that of PC / ABS alloy; it has lower density, which can effectively reduce the cost; excellent processing performance. ...
