Abstract
The invention aims at providing a preparation method of a hollow silicon dioxide spherical powdery material with overall performance meeting special requirements, belonging to the technical field of new materials and material modification. In the method, soft silicon is taken as a base material. The preparation method particularly comprises the following steps of: soaking the soft silicon by using a salt solution with the concentration of 10 ppm and saturation solubility for 10 minutes-24 hours; and then drying the soft silicon, and then carrying out torch firing on the soft silicon by using flames to obtain hollow spherical silicon dioxide. The preparation method of the hollow silicon dioxide spherical powdery material is simple; and the prepared hollow silicon dioxide has the advantages of low permitivity, light specific gravity, good flow property and can be wide applied to high-frequency cables, antennas, communication plates and the like.
Description
Technical field:
The present invention relates to novel material and material modification technical field, relate in particular to a kind of preparation method of hollow silica spherical powder material.
Background technology:
At present, nano silica powder material has been widely used in the fields such as machinery, daily-use chemical industry, biological medicine, construction industry, aerospace, agricultural, also present unusual characteristic at aspects such as sound, optical, electrical, magnetic and thermodynamics, also can be widely used in the aspects such as microelectronics, information material, coating, rubber, plastics, crop seeds treatment agent, rumbling compound, LED light diffusing agent, high grade refractory and papermaking.
Soft silicon is a kind of novel silicon-dioxide powdery material, English name siliesoft, the silicon-dioxide powdery material of a kind of particle diameter in 0.1～30 micrometer range, can be widely used in the fields such as machinery, daily-use chemical industry, biological medicine, construction industry, aerospace, agricultural, also present unusual characteristic at aspects such as sound, optical, electrical, magnetic and thermodynamics, also can be widely used in the aspects such as microelectronics, information material, coating, rubber, plastics, crop seeds treatment agent, rumbling compound, LED light diffusing agent, high grade refractory and papermaking.
And chemical constitution and the form of the development of modern high technology to material all proposed strict requirement, the particle surface of soft silicon materials has porous, there is larger internal space, thereby there is good adsorptivity, can be used as preparing novel material and material modified matrix.
Summary of the invention:
The object of the present invention is to provide a kind of over-all properties to meet the preparation method of the hollow silica spherical powder material of particular requirement, this preparation method is taking soft silicon as base-material.
Technical problem to be solved by this invention realizes by the following technical solutions:
A preparation method for hollow silica spherical powder material, is characterized in that, this preparation method's concrete steps are:
(1) with salts solution, soft silicon is soaked to 10min-24h;
(2) dry soft silicon;
(3) with flame, dried soft silicon is carried out to torch firing, make the spherical silicon dioxide of hollow.
Described salts solution is mixed with by soluble salt the aqueous solution that concentration is 10ppm-saturation solubility.
Described soluble salt is selected NaCl, Na
2sO
4or Ba(NO
3)
2.
Dry again after saline soak, the salt being adsorbed is stayed in the hole of soft silicon grain, carry out torch firing through flame method again, soft silicon grain is that silica dioxide granule is because of the vitrifying of being heated, because the vitrified temperature of silica dioxide granule is lower than the decomposition temperature of salt, so salt can decompose after silica dioxide granule vitrifying, and produce gas, vitrified silica dioxide granule is expanded, through cooling fast, finally form the silica dioxide granule of hollow.
The preparation method of hollow silica spherical powder material of the present invention is simple, and the hollow silica preparing has low dielectric constant, and light specific gravity, good flowing properties can be widely used in high frequency cable, antenna, communication sheet material etc.
