Description
Technical field
Paint field of the present invention, is specifically related to a kind of fire prevention electronic component powdery paints and preparation method thereof.
Background technology
Powdery paints is a kind of dry state pressed powder not containing organic solvent, it and the coating of common solvent type and aqueous
Coating is different, need not with solvent or water as disperse medium during application, but using air as disperse medium, application equably
After surface of the work, heating, form a kind of new coating of film, this be with the significant difference of other coating in place of.Powdery paints
It is the coating variety of a kind of high speed development, there is the advantage such as energy-conserving and environment-protective, three-waste free pollution, be used widely,
But fireproof is required higher by some electronic components, and powdery paints in the market cannot meet its requirement.
Summary of the invention
It is an object of the invention to provide a kind of fire prevention electronic component powdery paints and preparation method.
The invention provides a kind of fire prevention electronic component powdery paints, be made up of the component of following percentage by weight:
Preferably, described silicon powder particle diameter is 200 mesh.
Preferably, described firming agent is organic acid or acid anhydride type curing agent.
Preferably, described epoxy resin epoxy equivalent is 5000-10000g/eq.
Preferably, described expanded vermiculite powder make a living vermiculite in flake grind after high-temperature roasting prepare, particle diameter is 250 mesh.
Preferably, the polydimethylsiloxane being mainly composed of polyester modification of described organosilicon powder.
One, epoxy resin:
Epoxy resin is the organic compound referring to and containing two or more epoxide groups in molecule, in addition to indivedual,
Their relative molecular mass is the highest.The molecular structure of epoxy resin is to contain active epoxide group in strand for it
Feature, epoxide group may be located at the end of strand, centre or structure circlewise.Owing to molecular structure containing active ring
Oxygen groups, makes them can crosslink reaction with polytype firming agent and be formed and insoluble, insoluble have the netted knot of three-dimensional
The high polymer of structure.
Epoxy resin is one of very important thermoset macromolecule material, has adhesion strength high, and electrical insulation capability is good,
The advantages such as contractility is low, good processability, are widely used in each fields such as electronics, machinery, building.
The epoxy resin that the present invention selects epoxide equivalent to be 5000-10000g/eq is that primary raw material prepares powdery paints.
Two, silicon powder
Silicon powder is by natural quartz (SiO2) or vitreous silica (natural quartz amorphous state after high-temperature fusion, cooling
SiO2) through the multiple tracks processes such as broken, ball milling (or vibration, airflow milling), flotation, pickling purification, high purity water process
Micropowder.Silicon powder is a kind of Inorganic Non-metallic Materials nontoxic, tasteless, free of contamination.Owing to it possesses, temperature tolerance is good, acid and alkali-resistance is rotten
The excellent performances such as erosion, poor thermal conductivity, high insulation, low bulk, stable chemical performance, hardness are big, are widely used in chemical industry, electricity
The field such as son, integrated circuit (IC), electrical equipment, plastics, coating, senior paint, rubber, national defence.Swift and violent along with high-tech sector
Development, silicon powder also will step into new historical periods.
Silicon powder is widely used in high-grade high-performance low-cement refractory pouring material and prefabricated component, and service life is common cast
Three times of material, refractoriness improves about 100 DEG C, and elevated temperature strength and thermal shock resistance are all obviously improved.It is widely used in: coke oven,
The industries such as ironmaking, steel-making, steel rolling, non-ferrous metal, glass, pottery and generating.
Three, firming agent
Firming agent has another name called sclerosing agent, curing agent or set agent, is a class enhancement or material or the mixing controlling curing reaction
Thing.Resin solidification is through chemical reactions such as condensation, closed loop, addition or catalysis, makes thermosetting resin that irreversible change to occur
Process, solidification completes by adding solidification (crosslinking) agent.
The present invention selects organic acid or acid anhydride type curing agent.
Four, expanded vermiculite powder:
Vermiculitum is a kind of clay mineral similar to montmorillonite, for the silicate of layer structure.Typically by biotite through heat
Liquid corrosion becomes or air slaking are formed.There is (this is the biotite illusion of Vermiculitum) with thick biotite appearance sometimes in it, the thinnest
So micro-that to become soil shape.When Vermiculitum is heated to 300 DEG C, its expansion 20 times also bends.At this moment Vermiculitum is somewhat like water
Trematodiasis (is commonly called as Hirudo), and therefore it has had so one name.Vermiculitum is the most brown, yellow, dirty-green, has the gloss that oil is the same, adds
Lycoperdon polymorphum Vitt is become after heat.Vermiculitum can be used as construction material, adsorbent, fire-retardant insulating material, mechanical lubrication agent, soil conditioner etc.
Deng, of many uses.Fabric and raw-vermiculite sheet is after high-temperature roasting, and its volume energy expands rapidly several times to tens times, after volumetric expansion
Vermiculitum is just expanded vermiculite, and it is layer structure, and interlayer contains water of crystallization, and unit weight is at 50-200kg/m3, thermal conductivity is little, is good
Good heat-barrier material.The second best in quality expanded vermiculite, maximum operation (service) temperature is up to 1100 DEG C.Additionally, expanded vermiculite has well
Electrical insulating property.
The present invention selects expanded vermiculite powder to include as main modifying agent, the effect played: one is to utilize expanded vermiculite
The resistance to elevated temperatures of powder self, two is to utilize its layer structure, and after stirring, silicon powder, with it as carrier, therein may be used
To effectively play, temperature tolerance is good, acid-alkali-corrosive-resisting, the effect of high insulation.
Five, organosilicon powder
The main component of the organosilicon powder that the present invention uses is the polyxylene siloxanes of polyester modification.This kind is used to have
The Main Function of machine Si powder is: one is to be modified epoxy resin, improves the adhesion property of powdery paints, and two is 1000
Under high temperature more than DEG C, organosilicon powder can react with silicon powder in the carrier of expanded vermiculite powder, is formed a kind of attached
The network structure more closely on expanded vermiculite surface and inside, improve the fire protecting performance of coating.
Present invention also offers the preparation method of a kind of electronic component powdery paints of preventing fires, comprise the steps of
Step one: after being opened by blender, by epoxy resin-firming agent-expanded vermiculite powder-silicon powder-pigment-organosilicon
The order of powder-fluorescent material stirs in adding blender；
Step 2: being put into by the raw material stirred and heat in extruder and extrude, heating-up temperature is 80-140 DEG C, squeezes
