New energy automobile body material and preparation method thereof

Abstract

The invention provides a new energy automobile body material and a preparation method thereof, wherein the preparation method includes the following steps: 1) mixing epoxy-terminated silicone oil andpolyether amine at a temperature of 100-120 DEG C in the presence of a solvent, to prepare a premix M1; 2) placing epoxy resin, the premix M1 and polyether amine at a temperature of 80-100 DEG C, andmixing to prepare modified epoxy resin; 3) placing carbon fibers in an acidic solution, and soaking to prepare treated carbon fibers; 4) mixing the treated carbon fibers with an aniline aqueous solution in the presence of an initiator, then placing at a temperature of 50-80 DEG C, and stirring and mixing to prepare modified carbon fibers; and 5) mixing the prepared modified epoxy resin, the modified carbon fibers, nano clay, nano alumina and a processing aid, to prepare the new energy automobile body material. The light weight, good mechanical properties, corrosion resistance and other properties are achieved.

Description

technical field [0001] The invention relates to the field of automobile body materials, in particular, to a new energy automobile body material and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of living standards, people's requirements for daily necessities of life are getting higher and higher, and cars, as a convenient means of transportation, have become the most commonly used means of transportation for people's daily travel, and private cars are also It is becoming more and more common that many families already have multiple scooters. However, with the depletion of energy and the increasingly serious environmental pollution, traditional cars not only consume a large amount of non-renewable resources, but also have a greater impact on the environment due to the exhaust gas emitted by them. The massive increase has brought huge environmental pollution and other proble...

Problems solved by technology

[0003] The purpose of the present invention is to provide a new energy automobile body material and its preparation method to solve the problem that the existing automobile materials often have a relatively high density, resulting in a heavy vehicle weight and low battery life, so as to realize the reduction of its density. Under the premise, the tensile strength can be effectively improved, thereby effectively improving the impact resistance performance, and on this basis, further performance such as corrosion resistance can be achieved
