Problems solved by technology

In recent years, polyamide alloy materials have been more and more used in the field of auto parts, but due to its brittleness and fluidity defects, especially in online spraying, it is not resistant to organic chemical solvents, and is prone to stress cracking or spraying adhesion. Poor focus and other reasons have greatly restricted the use of polyamide materials in many applications.

Abstract

The invention belongs to the field of high molecular alloys and particularly relates to a polyamide resin alloy material for machining a ground brush of a dust collector. The polyamide resin alloy material comprises the following components in parts by weight: 20-80 parts of polyamide resin, 1-8 parts of an elastomer, 8-22 parts of glass fiber, 1-8 parts of polyolefin, 5-30 parts of a grafting body, 1-5 parts of functional master batches, 1-3 parts of black master batches, 0.2-0.5 part of an main antioxidant and 0.1-0.5 part of an auxiliary antioxidant. According to the polyamide resin alloy material, the polyamide resin, the elastomer, the glass fiber, polyolefin, the grafting body, the functional master batches, the black master batches, the main antioxidant and the auxiliary antioxidant are matched in use, and meanwhile, the use proportions of the components are reasonably optimized, so that the excellent properties such as the mechanical property and the heat resistance of a polyamide resin material are maintained, and furthermore, the fluidity, the solvent resistance and the online paint coating adhesiveness of the polyamide resin material are improved.

Description

technical field [0001] The invention belongs to the field of polymer alloys, in particular to a polyamide resin alloy material used for processing vacuum cleaner brushes. Background technique [0002] Polyamide resin has many excellent properties, such as mechanical properties, heat resistance, dimensional stability, self-flammability, etc., and its alloys are widely used in electronic appliances, auto parts, electric appliances and other fields. In recent years, polyamide alloy materials have been more and more used in the field of auto parts, but due to their brittleness and fluidity defects, especially in online spraying, they are not resistant to organic chemical solvents, and are prone to stress cracking or spraying adhesion. Poor focus and other reasons have greatly restricted the use of polyamide materials in many applications. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a polyami...
