preparation example Construction

[0025] The present invention as figure 1 A preparation method of a silicon dioxide composite material is provided as shown, and the specific steps are as follows:

[0026] Step 1. Weigh gas-phase nano-silica and auxiliary material A in proportion. The mass fraction of gas-phase nano-silica is 20-30 parts, the mass fraction of auxiliary material A is 20-40 parts, and auxiliary material A is a small molecule organic alcohol solvent Or the composition of small molecule organic alcohol solvent.

[0027] The present invention adopts gas-phase nano silicon dioxide as the basic material of the mechanical response material, and it can exhibit mechanical response characteristics under certain proportioning and process processing with auxiliary material A. The present invention has no special requirements on gas-phase nano silicon dioxide, as long as it has hydrophilicity, those skilled in the art can choose commercially available products.

[0028] In the present invention, the auxil...

Abstract

The invention provides a silicon dioxide composite material, application and a preparation method thereof. The preparation method comprises the following steps: mixing water and an auxiliary materialA according to a certain ratio to prepare a homogeneous solution M, adding the homogeneous solution M into gas-phase nano silicon dioxide to obtain a primary material, kneading at a certain rotating speed to obtain a mixed material, judging the state of the material, adjusting the ratio according to the state of the material, and discharging the mixed material meeting the state of the material. The mixture can generate intelligent mechanical response under the action of external force such as shearing and impacting, the material is changed into a solid state from a fluid state, and the strength and the hardness are increased accordingly; after the external force such as shearing and impacting is removed, intelligent mechanical response occurs again, the material is changed into a fluid state from a solid state, and the strength and the hardness are weakened accordingly; the prepared material can effectively absorb impact force, can be applied to the fields of intelligent shock absorption, intelligent shock prevention, intelligent protection and the like, and has a wide application prospect.

Description

technical field [0001] The invention relates to a silicon dioxide composite material, its application and its preparation method, and belongs to the technical field of intelligent materials. Background technique [0002] Smart material is a new type of functional material that can sense external stimuli, judge and process it appropriately, and can be executed by itself. It is the fourth-generation material after natural materials, synthetic polymer materials, and artificially designed materials. It is a modern high-tech new material. One of the important directions of development will support future high-tech development and realize structural functionalization and functional diversification. The development and large-scale application of smart materials will lead to a major revolution in the development of materials science. Generally speaking, smart materials have seven functions, namely sensing function, feedback function, information recognition and accumulation functio...
