Abstract

The invention provides a preparation method of continuous long glass fiber reinforced thermoplastic nylon and equipment for preparing the thermoplastic nylon. The method comprises the following steps: 1. adding glass fibers and a compatilizer to a reaction tank for performing grafting reaction, thus obtaining a product A; and 2. processing the product A in an infiltration unit and pulling out, cooling and drying the product A, thus obtaining the continuous long glass fiber reinforced thermoplastic nylon. The invention also relates to the equipment for preparing the thermoplastic nylon with the preparation method. The equipment comprises a shell, the reaction tank and the infiltration unit, wherein the reaction tank is communicated with the infiltration unit; the shell is made from wear-resistant steel subjected to carburizing and nitriding. The equipment has the beneficial effects that the binding force between nylon and the glass fibers is reinforced by adding the reaction tank for pretreating the glass fibers, so that the final product has very high performance; the preparation method and the equipment have the characteristics of low processing cost, high yield, high production stability and high material performance.

Description

technical field [0001] The invention relates to a preparation method and production equipment of glass fiber, in particular to a preparation method and equipment of continuous long glass fiber reinforced thermoplastic nylon. Background technique [0002] The glass fiber length of glass fiber reinforced thermoplastic nylon produced by traditional modification methods is generally less than 0.5mm, and the average length is 2-3mm. The main damage of the product is that the glass fiber is pulled out from the matrix. If it is pulled out from the base nylon, the strength of the product will be lower. At the end of the last century, continuous long glass fiber reinforced thermoplastic nylon (LFT) began to emerge in the foreign modified nylon industry. Compared with traditional glass fiber reinforced thermoplastic nylon, the glass fiber length of LFT is significantly larger than that of glass fiber in reinforced nylon produced by traditional methods. Due to the longer length of th...
