Hard nanosilicon dioxide material and preparation method thereof

Abstract

The invention discloses a hard nanosilicon dioxide material. The preparation method comprises the following steps: firstly treating nanosilicon dioxide by using silane to obtain nano silicon dioxide with the surface comprising amino groups, and then utilizing a methyl ethyl acrylate open-loop product aminocaproic acid to react with the amino groups on the surface of the nano silicon dioxide in thepolymerization process of the ethyl methylacrylate, thus obtaining the nano polymer material with high dispersity. Heavy calcium carbonate and Chile saltpeter and the like are added in the compositematerial, so that the hardness of a finished product is effectively improved; and by adding the stannous octoate and calcium stearate, the stability of the finished product is improved. The hard nanosilicon dioxide material is high in weather resistance and pressure resistance, wide in application range, and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a hard nanometer silicon dioxide material and a preparation method thereof. Background technique [0002] With the emergence of new technologies, people's research and understanding of polymer-based nanocomposites continue to deepen, and the preparation methods and production processes of nanocomposites are also constantly developing and enriching. In recent years, the methods of preparing polymer-based nanocomposite materials have also developed greatly, mainly including blending method, intercalation method, sol-gel method, in-situ method, masterbatch method, etc.; [0003] The comprehensive properties of polymer-based composites not only depend on the special functionality of the added fillers, but also the dispersion degree, size, compatibility and binding force of the dispersed phase in the matrix material have a greater impact on the comprehensive properties o...

Problems solved by technology

However, during the application process, the polar groups of the polyamide 6 material make it easy to absorb water, resulting in low dry and low temperature impact strength, poor product stability, easy plastic deformation due to friction, and severe wear. In addition, as a mine The use of engineering plastics does not have antistatic properties and is prone to gas explosions, etc., which affects the dimensional stability, anti-wear and anti-friction properties and electrical properties of its products, which limits its application range;
