Abstract

The invention discloses nylon 6 with 50% of glass fiber plastic and an injection molding method. A finished product is prepared from the following raw materials in percentage by weight: nylon 6, glass fiber and imported color concentrate. The preparation method comprises the following steps: (A) selecting the raw materials: the nylon 6, the glass fiber and the imported color concentrate; (B) adding corresponding raw materials according to the requirements of the step (A), and adding the selected aluminate coupling agent; (C) using plastic particles, 2% of imported color concentrate and liquidparaffin in the step (B) as auxiliary materials, and adding the auxiliary materials into a stirrer to be uniformly stirred and then packaging separately; (D) drying the materials which are uniformly stirred in the step (C) in a special electrothermal blowing dry box with constant temperature or a dryer provided by equipment; and (E) processing the materials by injection molding. The finished product has the advantages of reasonable formula, high tensile strength and bending strength, high thermal property and resistance to chemical attack, and the total cost can be saved by more than 50%. Theinjection molding method has the advantages of simple process, high efficiency, low cost and capable of mechanized mass production.

Description

technical field [0001] The invention relates to the technical field of injection molding of plastic products, more specifically relates to a nylon 6+50% glass fiber plastic material, and also relates to an injection molding method of a nylon 6+50% glass fiber plastic material. Background technique [0002] As a new type of power supply system for feeding mobile mechanical equipment, the sliding wire needs to play a safe role in preventing rain, dust, snow and electric shock. Sliding wires are simple in structure, easy to install and maintain, and are widely used in power supply lines for mobile equipment such as mines, metallurgy, chemicals, machinery, docks, and freight yards. However, to meet its various requirements, there are high requirements on raw materials and processes. Therefore, what kind of raw materials and process equipment to choose has become a key issue faced by various plastic production suppliers of crane slide wires in the world. [0003] Sliding wire pr...
