Description
Technical field
The present invention relates to protective coating technique fields, and in particular to a kind of inorganic high-temperature resistant cementing compositions and fluid sealant with
Preparation method and application.
Background technology
Inorganic coating is to use ceramics or glass state material and part metals, adds and is coated in metal or ceramic surface to reach increasing
It imitates and a kind of film layer for purpose of lengthening the life.Such as heat-resisting, the antioxidant coating applied in terms of aerospace, the temperature control applied on satellite
Coating, the wear-resistant coating applied in mechanical industry are applied in the biological coating and chemical industry applied on artificial body resistance to
Soda acid coating etc..According to different purposes and use environment, the technique of inorganic coating is also different.Cladding process is by inorganic compound
Coating is tuned into slurry, with brush, spraying, wire mark the methods of coated in ceramics or metal substrate surface, then in low temperature or room
Temperature is lower to be cured or burns till at high temperature.Spraying process be directly with the inorganic compound powder centainly matched, by high temperature spray gun,
The surface for spraying to metal substrate forms.Vapour deposition method is a kind of technology that material evaporation is made to be deposited on by painting device surface,
Thickness is only millimicron to micron order, applied to extremely fine and more special occasion.Inorganic coating is widely used at present
Various fields.The artificial satellite cover of various models successfully applies thermal control coating.Plasma spraying multi-layer composite coatings,
Heat-insulated thermal protective coating as large rocket engine jet pipe and the sealing ring and axis for being widely used in chemical industry, machinery field
It holds and waits wear parts.Sunlight absorption rate very high do not burn coating and black enamel are used as photothermal conversion on solar water heater
Coating is applied.Oxide-coated artificial bone and cermet tooth is sprayed on metallic matrix to answer what clinic succeeded
With.
The fast development of plastics industry also brings a series of social concerns caused by waste plastic and rubbish waste plastics.
Deep people is to the every nook and cranny of society for the application of plastic products, and from industrial production to clothing, food, lodging and transportion -- basic necessities of life, plastic products are ubiquitous.People
Start to find, plastic garbage stealthily to we gushed come, drastically influence our health and living environment, such as
Some agricultural lands start the underproduction due to influence of discarded mulch, and " white pollution " that waste plastics triggers starts that people is allowed to have a headache,
The Undec cutlery box of without putrefaction can not be recycled effectively, and life is had no way of doing it processing with plastic garbage.Plastic refuse increase severely and by
Society caused by this and environmental problem pendulum put the place for existence of living in whole world people in face of people.
In the prior art, the coating of plastics is focusing more on plastic coating.In inorganic adhesive, when heating temperature is more than
The softening point or decomposition temperature of high molecular material, also lose the effect of coating.For heat safe resin, coating is used as
For adhesive effect it is poor.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of inorganic high-temperature resistant cementing compositions and sealings
Glue and preparation method and application, solve the problems, such as coating non-refractory.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of inorganic high-temperature resistant cementing compositions, are made of following component：
Adding liquid sodium metasilicate, aluminium silicate powder, magnesia, silicon nitride and quartz sand in inorganic high-temperature resistant cementing compositions,
It is inorganic raw material, at low cost, melting temperature is high, and superficial attractive forces are strong；Good seal, it is easy to use, it is water-fast corrosion-resistant；In temperature
It spends in the environment for being 0.1-50MPa for 20-700 DEG C and pressure, adhesive strength is big, favorable sealing property.
Liquid sodium silicate is liquid, has colourless clear viscous shape and the light color translucent.Main component is silica
(SiO2) and sodium oxide molybdena (Na2O), the raw material of two kinds of mode of appearance production and processings of viscous liquid is soda ash and quartz sand.
For aluminium silicate powder as functional aid, it can be widely used for environment-friendly water-based building coating, ink, plastics, rubber, skin
The fields such as leather, printing and dyeing, papermaking.Add in indoor and outdoor building coating, printing coating slurry, outside leather casein finiss, alkyd paint, acrylic acid
In the products such as wall paint, powdery paints, white base coat, road marking paint, titanium white synergistic effect is generated, saves titanium dioxide dosage
About 15~25%, therefore product cost can be greatly lowered, and properties of product are may significantly improve, such as whiteness, dry film covering power, storage
Stability, weatherability, wear resistance, scrub resistance etc.；Also the workability of product can be improved, such as reduce the thermoplasticity of film,
Improve the tackiness, dust absorption etc. of surface.The thickening that priming paint can be made somewhat slight so as to improve its brushability, is prevented vertical
The sagging phenomenon of application.
Magnesia goes out a system with the demand and development in industrialization upgrading and new and high technology functional material market, development ＆ production
High-new fine magnesium oxide product is arranged, is mainly used for senior lubricant, advanced tanning carries basicity grade, food-grade, medicine, silicon steel grade, height
Nearly ten kind compositions such as grade electromagnetism grade, high-purity magnesium oxide.
Silicon nitride is a kind of important structural ceramic material.It is a kind of superhard substance, itself has lubricity, and resistance to
Abrasion is atomic crystal；It is anti-oxidant during high temperature.And it can also resist thermal shock, be heated to 1000 DEG C or more in air,
Quick refrigeration drastically heats again, will not fragmentation.There is so excellent characteristic just because of silicon nitride ceramics, people are usually sharp
