Abstract
The invention belongs to the various fields constructed with hydrophobic silicon dioxide aerogel coating or putty, it is mainly used in the construction operation for needing to carry out other aqueous coatings on hydrophobic silicon dioxide aerogel coating or putty surface in various fields, which is mainly characterized in that the mass percent of raw material and its each component is：Solvent：85~90 parts, wetting agent：3~5 parts, adhesive promoter：5~7.5 parts, water-retaining agent：3~5 parts.
Description
Technical field
The invention belongs to the various fields constructed with hydrophobic silicon dioxide aerogel coating or putty, are mainly used for various
The construction for needing to carry out other water-based materials in field on hydrophobic silicon dioxide aerogel coating or putty coating surface is made
In industry, to improve the performance of hydrophobic silicon dioxide aerogel coating or putty coating surface, it is made to be changed into pole by nonpolarity
Property, in order to the attachment of other water-based materials.
Background technique
Each aerosil manufacturer and research unit all put into great effort on domestic and international market at present
Onto aeroge composite felt and aerogel powder research, and about hydrophobic nano-silica aeroge thermal insulation coatings or heat preservation
The product of putty is rarely reported, and correlative study is also fewer, with hydrophobic nano-silica aeroge thermal insulation coatings or heat preservation
The matched Related product of putty is even more fewer and fewer.
Hydrophobic nano-silica aeroge coating or putty have heat insulation effect is good, thermal coefficient is low, water absorption rate is low,
Fire resistance rating height, high temperature resistant, it is environmentally protective the features such as, had both the organics such as traditional polystyrene type, polyurethanes, phenolic
The advantages of inorganic heat insulation materials such as thermal insulation material and thermal insulation mortar, heat preservation rock, inorganic heat preservation fiber is a kind of environmentally protective
New material, but hydrophobic nano-silica aeroge coating or putty, due to whole hydrophobicity, coating surface is in
Reveal nonpolarity, is greater than 90 degree with the contact angle of water under normal conditions, so that other aqueous materials are difficult to be attached to its table again
Face, is not easy to the construction and practical application of other materials, therefore develops a kind of change hydrophobic nano-silica aeroge
The surface size of the performance of coating or putty coating.
Summary of the invention
It is an object of the invention to prepare a kind of hydrophobic silicon dioxide aerogel coating or putty coating surface size,
Hydrophobic silicon dioxide aerogel coating or putty coating surface property can be made to change using this surface size, i.e., by
Nonpolarity is changed into polarity, makes the contact angle of its surface and water by being greater than 90 degree of transformations less than 90 degree.
The raw material of this surface size and its mass percent of each component are：Solvent：85~90 parts, wetting agent：3~
5 parts, adhesive promoter：5~7.5 parts, water-retaining agent：3~5 parts.Its preparation flow is as follows：
Deionized water or industrial tap water, wetting agent, adhesive promoter, water-retaining agent are added to the container, high speed is started
Dispersion machine disperses certain time.
Wetting agent is sprayed on hydrophobic silicon dioxide aerogel coating or greasy with special construction tool in use process
Sub- coating surface.
Specific embodiment
Below in conjunction with example, technical scheme of the present invention will be further described, but is not the limitation to invention.
Example 1
Each component raw material and component are as follows：
Example 2
1 example 1- example 2 of table is connect with using hydrophobic silicon dioxide aerogel coating after wetting agent or putty coating surface
Feeler θ
