Abstract

The invention discloses a spraying-facilitating mineral enhanced PA66 material and a preparation method thereof. The spraying-facilitating mineral enhanced PA66 material is prepared from the followingraw material components: 45 to 55 parts of PA66, 25 to 35 parts of PA6, 15 to 30 parts of mineral fillings, 0.1 to 0.2 part of an antioxidant, 3 to 5 parts of an acid absorbent and 2 to 3 parts of asurfactant, wherein the mineral filling is talc grains of 2,500 meshes, and the part is mass part. According to the spraying-facilitating mineral enhanced PA66 material disclosed by the invention, through synergism and promotion of all the raw materials, on the basis that the mechanical property, the size stability and the temperature resistance of the material are all improved, the surface adhesion of a product is enhanced by adding the acid absorber and the surfactant, so that the product is only required to be washed with water, and burning and surface grinding are not required; the productis easy to spray; the productivity is improved, and the cost is reduced; moreover, the production rejection rate is also reduced.

Description

technical field [0001] The invention relates to an easy-to-spray mineral reinforced PA66 material and a preparation method thereof, belonging to the field of PA66 materials. Background technique [0002] Polyhexamethylene adipamide (PA66) is a linear thermoplastic engineering plastic. Its molecular structure and crystallization make it have excellent physical and mechanical properties. Mineral-filled reinforced PA66 composites are widely used in the automotive industry, typically represented by automotive hubcaps. After the hub cover is formed, it will go through many complicated processes such as washing, burning, and grinding before it can be sprayed on the surface. After the sprayed product is left for a period of time, it will be easy to fall off the paint, which will increase the scrap rate of the product. The complicated process will reduce the output and increase the cost. Development is imminent. Contents of the invention [0003] The invention provides an easy-...
