Problems solved by technology

However, in the production process of glass fiber reinforced polypropylene, the glass fiber is difficult to cut, so that the length of the glass fiber is too long, the dispersion is uneven, and the inside of the bundled glass fiber cannot be effectively wetted with the resin, so there is stress concentration in the bundled glass fiber , often block the die hole, which will cause groups of glass fiber fluff and broken strips at the exit of the die hole, making the product look rough and not smooth enough
In addition, the content of glass fiber is also difficult to control and stabilize
In order to solve this problem, it is usually to strengthen the shear of the screw, but this method is at the cost of destroying the length of the glass fiber, which will lead to a decrease in product performance

Abstract

The invention discloses a high-rigidity glass fiber reinforced polypropylene material and preparation equipment and a preparation method thereof. The high-rigidity glass fiber reinforced polypropylenematerial consists of the following raw materials: homo-polypropylene, a compatilizer, an antioxidant, a lubricating agent, a nucleating agent and glass fibers. Meanwhile, the invention discloses theequipment for preparing the polypropylene material and a method for preparing the high-rigidity glass fiber reinforced polypropylene material by using the equipment. In addition, the invention furtherdiscloses application of the high-rigidity glass fiber reinforced polypropylene material. The polypropylene material has high bending strength and modulus, is excellent in anti-impact property and good in thermal stability, resists hydrolysis, and can be widely applied to automotive panels, washing machine drums, handles of thermal jugs and the like.

Description

technical field [0001] The invention relates to a high-rigidity glass fiber reinforced polypropylene material and its preparation equipment and preparation method, belonging to the technical field of polymer materials. Background technique [0002] Polypropylene is one of the five general-purpose resins. It has the advantages of light weight, easy processing, and good chemical resistance. It has been widely used in chemical, electrical, packaging and other industrial fields. However, with the gradual expansion of the demand for polypropylene in construction, automobile, shipbuilding and other industries, people put forward higher requirements for its performance. Generally, polypropylene can be modified to meet more applications through reinforcement, toughening, blending and other modification methods. . [0003] As a general-purpose engineering plastic, glass fiber-reinforced polypropylene has excellent properties such as high strength, high stiffness, rigid impact streng...
