Abstract

The invention provides a double-screw assembly for extrusion molding processing of nylon and glass fiber, and a processing method thereof. The double-screw assembly for extrusion molding processing ofthe nylon and the glass fiber comprises two screw rods meshing with each other, wherein each screw rod comprises multiple screw elements and multiple kneading elements; each screw rod is divided intoa conveying section, a conveying and compressing section, a plasticizing and mixing section, a first dispersing and mixing section, a glass fiber feeding section at the natural exhaust side, a glassfiber distributing and mixing section, a second dispersing and mixing section, a vacuum exhaust section and a conveying and homogenizing section connected sequentially; the screw elements comprise 22 / 11, 22 / 22, 32 / 32 or 48 / 48; and the kneading elements comprise 45 / 5 / 22, 45 / 5 / 32 or 90 / 5 / 32. The invention further provides the method for carrying out nylon extrusion molding processing on the double-screw assembly. The double-screw assembly provided by the invention is good in matching performance, an extruded material bar is smooth in surface and dense inside, no bar breakage phenomenon occurs during the extrusion process, the extruding pressure of a machine head is normal, the material bar is uniformly diced, and the product performance is good.

Description

technical field [0001] The invention relates to the technical field of nylon extrusion processing, in particular to a twin-screw combination for nylon and glass fiber extrusion processing and a processing method thereof. Background technique [0002] Nylon is the most diverse and widely used engineering plastic in the world. The main varieties are: nylon 6 (PA6), nylon 66, nylon 610, etc. Nylon 6 is used in many fields, but nylon 6 is flammable. Flame retardant nylon 6 with insulation performance is very necessary. At present, most people use the method of adding halogenated flame retardants in the flame retardant modification of nylon 6; The use of flame retardants has increasingly become a hot spot and an important direction for the development of flame retardant materials. Glass fiber reinforced halogen-free flame-retardant PA6 is an important halogen-free flame-retardant engineering plastic, mainly used in electronic appliances, electrical switches and other fields. ...
