Problems solved by technology

It not only solves the problem that the internal mixer and extruder cannot form continuous processing and production, but also effectively improves the uniformity of plasticizing, melting and modification of waste plastics, and at the same time improves the feeding capacity of the equipment, making it not only suitable for It is not only suitable for the feeding of leftovers from the production of GMT materials for vehicles that have not been pre-broken, but also adapted to the feeding of large pieces of recycled GMT parts for used vehicles, so there is no need to crush waste plastics, avoiding the impact on labor caused by noise and dust during crushing hazards, while saving process steps and reducing production costs

Embodiment 1

[0046] Example 1. In the example of the present invention, GMT punching scraps (glass fiber felt-reinforced polypropylene-based composite material, component GF / PP) are taken from the ceiling of the automobile interior decoration, wherein the content of glass fiber is 40wt%. First add the GMT punching scraps to the feeding device, and at the same time add modifiers with compatibility and coupling properties, maleic anhydride grafted polypropylene PP-g-MAH, acrylic acid grafted polypropylene (PP-g-AA ), silane coupling agent KH-550 and ethylene bis stearyl EBS lubricant. When adding modifiers, the weight ratio of waste GMT leftovers to each modifier is 100:5:5:3:4. The material in the above-mentioned feeding device is forced to be fed into the banburying and melting chamber under the screw extrusion of a pair of multi-edged helical rotors. The temperature of the banburying and melting chamber is controlled at 200°C. The input heat and the shearing, crushing, extrusion and knea...

Embodiment 2

[0054] Embodiment 2, in the embodiment of the present invention, get the automobile wheel cover GMT punching scrap (glass fiber mat reinforced polyethylene terephthalate / polypropylene-based composite material, composition GF / PP / PET), wherein the glass fiber The content is 30 wt%, and the content of polypropylene is 20 wt%. First add the GMT punching scraps to the feeding device, and at the same time add modifiers with compatibility and coupling properties, maleic anhydride grafted polypropylene PP-g-MAH, acrylic acid grafted polypropylene (PP-g-AA ), silane coupling agent KH-550 and ethylene bis stearyl EBS lubricant. When adding modifiers, the weight ratio of waste GMT leftovers to each modifier is 100:5:5:3:4. The material in the above-mentioned feeding device is forced to be fed into the mixing and melting chamber under the screw extrusion of a pair of multi-edged helical rotors. The temperature of the banburying and melting room is controlled at 260°C. The input heat and...

Abstract

The invention discloses a waste GMT material recycling granulation method for a vehicle and a special device thereof. According to the device, the mixing characteristic of an internal mixer and the moldability of an extruder are fully utilized. The problem that continuous processing production cannot be realized by the internal mixer and the extruder is solved, the plastifying, melting and modifying uniformity of waste plastics is effectively improved, the material feeding capacity of the equipment is improved, and the device adapts to feeding of GMT material production leftover materials for vehicles which are not crushed in advance and also adapts to feeding of large waste GMT recycling parts for vehicles. Therefore, the waste plastics do not need to be ground, the hazards caused to the labor due to the noise and dust during crushing are avoided, the process steps are saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for recycling and granulating waste plastics for vehicles and a special device thereof, specifically, a method for recycling and granulating waste GMT materials for vehicles and a special continuous mixing extrusion granulation device. Background technique [0002] With the development of automobiles in the direction of lightweight, energy saving, emission reduction, comfort and beauty, the amount of plastic used in the automotive field is increasing day by day, and its amount and its application technology often become an important indicator to measure the level of a country's automobile industry. However, unexpectedly, it is precisely because of the large-scale application of these plastics that they become durable and non-perishable garbage after use or consumption. Over time, it will further aggravate the global "white pollution" problem and directly affect people's quality of life. It even threatens people's physi...
