Description
Technical field
The present invention relates to technical field of coatings, more particularly, to a kind of smoke-free and tasteless fire-proof and thermal-insulation moisture gel aqueous inorganic
Ceramic coating and preparation method thereof.
Background technique
Aerosil be mutually assembled by colloidal particle a kind of structure-controllable constituted light nanoporous it is non-
Crystalline material, is the most light solid material being currently known, the minimum density that laboratory is done at present can down to 3 kilograms/cubic metre,
Industrialized production it is basic at 10-80 kilograms/cubic metre or so.Since it is with special continuous tridimensional network, in institute
Have in solid material, its heat-proof quality is best, and acoustic propagation rate is low, and dielectric constant is low, and reference area is big, therefore is answered extensively
For heat preserving and insulating material, acoustic impedance coupling material, prepare efficient rechargeable battery material, catalyst and its carrier etc..Dioxy
The thermal coefficient of SiClx aeroge is extremely low, and (25 DEG C) thermal coefficient can reach 0.008W/mk under room temperature.Therefore it is widely used
To various heat preservations, heat-insulated field.Why aerogel material has very excellent heat preservation and insulation, is its special hole knot
Structure, using the various products that aeroge is made into as main material, such as aerogel heat-proof blanket, heat insulation felt, the shaped pieces such as thermal insulation board are wide
It is general to be applied to various industrial heat preservations, heat-insulated field.Aerogel heat-proof shallow layer (coating is less than 5 millimeters thicks), since its is excellent
Heat-proof quality and workability make it in building energy conservation, energy environment protection, aerospace, oil pipeline, solar energy heating, stove
The fields such as heat preservation have great application potential；
Paint development has been required to today by coating functionalization, Focus.Insulating moulding coating is just concerned by people in the recent period
Product makes people energy-saving because having the function of insulation, is suitble to modern life requirement, so insulating moulding coating
It is the faster a kind of functional paint of development.More and more demand such as vehicles now, while considering the comfort of vehicle
It is more to consider its security performance, to the collision in vehicle driving process itself, the security performances such as failure pass through at present to be added
Air bag, measures such as safety belt etc. are filled, but the shellproof explosion-proof performance of vehicle itself is not strengthened, especially in chaos caused by war
Country, the attack of terrorism happen occasionally, and occupant requires the security performance of the anti-fried protection of vehicle higher and higher.Aeroge coating is made
It to can be convenient is coated in the surface of material, is not limited by the shape of material and structure, the aeroge in coating has again
The protection of the explosion-proof function of good insulation, the explosion wave of the protection and automobile bottom first as automobile cabin has one
Fixed booster action, aeroge apply be in coating industry coating industry revolutionary advancement, be novel insulating moulding coating, one
As insulating moulding coating be all using thicken or reflection by the way of be thermally shielded, but under high standard or extreme condition, it is general every
Hot coating is unable to satisfy requirement, and aeroge is added in coating so people develop, and by silica aerosil microballoon and gathers
Object coating is closed when being mixed with compound heat-insulation coating, can not be limited by space, area and heat-insulated object shapes, it only need to should
Insulating moulding coating is coated on heat-insulated object, to improve the thermal insulation of coating, take full advantage of coating application convenience and aeroge every
The characteristics of in terms of hot property excellent two.
In view of the elite clone characteristic and broad application prospect of aeroge, many people grind the preparation of material
Study carefully, but the aeroge coating manufacture craft of the prior art, generally directlys adopt and aeroge is rolled into crushing or directly prepares airsetting
The method at rubber powder end, the aerogel powder particle prepared is larger, particle diameter distribution is uneven, porosity is low, and aeroge is caused to apply
The final product quality of material is poor, and heat-proof quality is poor；Simultaneously in mixed process, by the way of being vigorously stirred, also it be easy to cause
Aeroge is damaged, to influence product quality；
Silica aerogel particles typical production process is divided into supercritical drying and atmosphere pressure desiccation, supercritical drying one
As using organosilicon as silicon source, including methyl orthosilicate (TMOS), ethyl orthosilicate (TEOS), multi-polysiloxane (E-40) and other
Organosiloxane etc. makees solvent with dehydrated alcohol, prepares alcogel by sol-gel technology, then uses supercritical drying
Legal system prepared silicon dioxide aerogel particle.Atmosphere pressure desiccation is generally using inorganic silicon as silicon source, including industrial waterglass, acid silicon are molten
Glue, alkaline silica sol etc. prepare hydrogel by sol-gel technology, then with low surface tension solvent pair with water as solvent
Gel carries out solvent replacement, is then alkylated modified place to the hydrogel with trim,ethylchlorosilane or hexamethyldisilazane
Reason, finally through constant pressure and dry legal system prepared silicon dioxide aerogel particle, since supercritical drying needs high temperature and pressure process, the energy
Consumption is big, and technique is cumbersome, has certain risk, and yield is lower, is unfavorable for industrialized production, high cost seriously restricts
The popularization and application of aerosil；And product prepared by atmosphere pressure desiccation in terms of exist not
Foot.In addition to the performances such as hydrophobicity, flexibility and the mechanical strength of product are improved, it usually all can be modified using additional surface
Step, which further improves production costs.

Hydrophobicity, heat preservation heat-insulating property aerosil product outstanding is prepared in solution.
Currently, preparing silica aerogel particles in process of production all using supercritical drying and atmosphere pressure desiccation
Face respective problem: supercritical drying needs to be typically designed 10~30MPa of pressure resistance, belonged to special equipment with high pressure resistant reaction kettle,
Fabrication cycle length, investment are big, and there is certain danger in operational process, and equipment investment is surprising if production capacity to be improved；Normal pressure
Seasoning solvent replaces the time long (general 1~2 day, some meetings are longer), alkylation modification handles the time long (20~48h), no
It is long (6~10h) that drying time is classified under synthermal gradient, so that the entire silica aerogel particles production cycle is long, production
