Abstract

The invention provides a preparation method of continuous long carbon fiber reinforced nylon and equipment for preparing the nylon. The method comprises the following steps: 1. adding carbon 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 carbon fiber reinforced nylon. The invention also relates to the equipment for preparing the 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 carbon fibers is reinforced by adding the reaction tank for pretreating the carbon 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 carbon fiber, in particular to a preparation method and equipment of continuous long carbon fiber reinforced nylon. Background technique [0002] The carbon fiber length of carbon fiber reinforced nylon produced by the traditional modification method is generally less than 0.5mm, and the average length is 2-3mm. The main damage of the product is that the carbon fiber is pulled out from the matrix. The shorter the carbon fiber, the easier it is to pull out from the matrix nylon. , the lower the strength of the product. At the end of the last century, continuous long carbon fiber reinforced nylon (LFT) began to emerge in the foreign modified nylon industry. Compared with traditional carbon fiber reinforced nylon, the carbon fiber length of LFT is significantly larger than that of carbon fiber in reinforced nylon produced by traditional methods. Due to the longer length of carbon ...
