Description
Technical field
The present invention relates to a kind of strong fire proofing material of effect of heat insulation and its preparation technology, belong to special material technical field.
Background technology
There is mainly low ignition point material and do not protected in fire, if a kind of high-temperature resistant coating can be coated on furniture
Surface, reduces being applied the combustibility of material surface, blocking spreading rapidly for fire, is applied material fire endurance in order to improve, will
With effective protection low ignition point delays of material or the generation of fire can be prevented.This project is using Alumina gel and kieselguhr as main original
Material, invention is a kind of to be had with low cost, environmental protection, purify air, effectively improves the new coating of base material refractory ability.Mesh
Before, what indoor wall coating was most is emulsion paint, and emulsion paint is a kind of organic coating, can constantly exclude harmful volatilization
Property gas（VOC）, though many coatings enterprises release environmental protection, the emulsion paint of net taste, cannot fundamentally solve harmful substance
A kind of impact to environment, it is therefore desirable to inorganic coating, thoroughly eliminates the discharge of VOC, and Alumina gel is a kind of preferably selection.
Due to economic fast development and the quickening of urbanization rhythm, the living environment and living environment of people are not all allowed to find pleasure in
See, be primarily present problems with：Respirable dust granule increases to be increased with harmful gas concentration.Under the high temperature conditions, general painting
Material can occur degraded and the process of carbonization, cause breakdown of coating, do not have protective effect, and high-temperature resistant coating has in hot conditionss
Under remain to the characteristics of keeping certain physical and chemical performance, make inner substrate high temperature resistant, so as to extend its service life, play protection
Effect.
The 50's of 20th century, people put into substantial amounts of energy research high-temperaure coating and coating.With modern work
The metal materials such as the development of industry sophisticated technology, the steel alloy that commonly uses at present, heat resisting steel also can not meet the requirement of development, because
The too high generation creep of temperature, or the destruction that makes coating too fast because of the effect of high temperature gas flow or flaking, so as to service life contracts
Short.In order to eliminate or delay the generation of this phenomenon, and improve service life, it is necessary in metal material surface or other materials
The various fire-proof high-temperature resistant coating of surface-coated.Fireproof coating is for flammable substrates surface, can reduce being applied material surface
Combustibility, retardance fire spread rapidly, applied material fire endurance so as to increase rescue and escape time in order to improve, had
The effect protection person and property safety.Fireproof coating is coated in substrate surface, in addition to fire retardation, also there is antirust, prevent
The performances such as water, anti-corrosion, wear-resisting, heat-resisting and coating tenacity, coloring, adhesion, easy dryness and certain gloss.Fire prevention is applied
Material species is more, and invention is a kind of inorganic coating, intends with Alumina gel as solvent, with kieselguhr as fire proofing additive and work(
Energy auxiliary agent, along with other auxiliary agents are formed, prepares a kind of new environmental protection fire prevention, high temperature resistant inorganic coating.
At present, kieselguhr is added in coating is used for eliminating formaldehyde, purify air, keeps humidity, achieves certain
Effect, but the high temperature resistant of kieselguhr itself, heat-insulated performance do not give full play of.This patent will give full play to kieselguhr
With the characteristic of Alumina gel, a preferably performance is reached.
