Description
Technical field
The invention belongs to field of organic silicon, relate in particular to a kind of organosilicon coating and preparation method thereof.
Background technology
In the electronic product, printed circuit board (being pcb board) is the interconnective main carrier of realizing between the various electronic devices and components.Be densely covered with the conducting wire on the pcb board; Surface-coated solder mask (be generally green or brown) and silk screen printing face (being the icon face); In the processing and use of pcb board, to its surface carry out " three anti-" and insulation protection particularly important, and general crylic acid resin and polyurethanes insulation compound to solder mask bonding relatively poor, hardness is high, poor flexibility; Broken easily; And hot setting or UV solidified during great majority needed, and in a lot of occasions, especially should not operate during large-area construction.
Develop rapidly along with the electronic information industry; Printed circuit board (being PCB or PWB plate) and various electronic devices and components are tending towards precise treatment, high performance and production and use robotization; It is more and more important that the insulation protection processing is carried out on its surface, also increasingly high to its material requirements of handling usefulness.With respect to other rubber or resin material, has the request for utilization that excellent electric insulating, snappiness, self-repairability, high-intensity organosilicone elastic coating more can satisfy electronic devices and components and pcb board after a kind of self cure, easy to use, LV, the curing.
Abroad; Be used for the electronic product industry organosilicone elastic coating research and use comparatively ripe; 1C49LV, 1C51,1C49,1C55, the 1C53 that produces like: U.S. Humiseal company is the three anti-glue that are used for electronic circuit and components and parts waterproof, protection against the tide, mildew-resistant, antirust, insulation, protection usefulness; The DC1-2577 that the manufacturing giant's Dow corning of world's Zylox company produces, but its also defective to some extent aspect soft, H.T., and imported product expensive.At home; There are some to be used for the research and the application of the weather-proof waterproof type organosilicon coating of building materials aspect; But the research and the application that are used for the surface-treated single-component room temperature vulcanized organosilicon elastic coating of electronic product industry, particularly pcb board and electronic devices and components are still lacked.Along with further developing of electronic product industry, the application of organosilicone elastic coating in the electronic product field remains further to be developed.
The ketoxime removing type organosilicone elastic coating, owing to adopt aromatic hydrocarbon such as replacement benzene,toluene,xylene such as solvent oil or sherwood oil to make solvent, it is the solvent oil volatilization in sulfidation; Emit ketoxime; Be neutral, low smell, except that copper being had the slight corrosion, to other base material non-corrosiveness; Bonding wide, be specially adapted to electron trade, automobile industry, household electric appliances.
When applying pcb board and electronic devices and components; Can adopt brushing, spraying, dip-coating, four kinds of operating procedures of choice of equipment property coating; All need a kind of product, and also do not have this Products Development both at home and abroad with characteristics such as LV, low smell, fast levelling, fast curing, nothing corrosion.
The pcb board three anti-lacquers that use both at home and abroad mainly contain crylic acid resin, polyurethanes and silicone based insulation compound.Acrylic acid or the like insullac is the three anti-lacquers that generally use in the market, has the advantage of surface drying quick solidifying, but higher, the poor toughness of hardness of paint film after solidifying, and weather resisteant and resistant of high or low temperature can not show a candle to organosilicone elastic coating; Polyurethanes three anti-lacquers have good low temperature resistant, anti-solvent and moisture resistivity, but the paint film embrittlement, weathering resistance and high thermal resistance can not show a candle to silicone based elastic coating; Acrylic acid or the like and polyurethanes three anti-lacquers are mainly used the fragrant same clan, the ester class, and ketone is as solvent, as: toluene, ETHYLE ACETATE, acetone, turps, hexanaphthene, these solvent toxicity are bigger, after the volatilization, HUMAN HEALTH and environment damaged to some extent.The existing RTV-1 type organosilicon coating that puts goods on the market; Be with in low viscous α; Alpha, omega-dihydroxy polydimethyl siloxane is that basic glue, organotin inner complex are catalyzer; Methyl tributanoximo silane, vinyl tributanoximo silane be as linking agent, the third amino triethoxyl silane tackifier, add filler, solvent is formulated.Mainly there are 4 problems in the product that this prescription is processed: 1, surface drying time is long, and inside solidification speed is slow, influences the client and uses; When 2, using as three anti-lacquers, bad to institute's contact substrate cementability, be prone to peel off; 3, the formed paint film intensity of product is lower, elasticity is relatively poor, hardness is higher, finally causes toughness relatively poor, and is in use broken easily; 4, contain the part aromatic solvents, toxicity is bigger.
For this reason, the problem that solution RTV-1 organosilicon coating application facet faces becomes the major objective of research and development, shows: 1, improve the vulcanization rate of RTV-1 organosilicon coating, shorten surface drying time and set time; 2, improve the cementability of coating to base material; 3, gain in strength, reduce hardness, improve toughness; 4, use the solvent of low smell low toxicity.
Along with development of science and technology; Electronics is integrated increasingly high; The preparation of precise electronic components and parts is used more and more widely, and pcb board has been widely used in various electronic integrated circuits, Auto Electronic Controlled System, household appliances manufacturing, in covering pcb board and electronic devices and components piece process; In order to reach satisfied performance, need product to have following character:
1, satisfy the required LV property of coating processes: viscosity is excessive, and after the coating, leveling characteristics is poor, behind the coating surface drying, can not flow to certain area, and cause coating thickness blocked up, and usage quantity increases, and causes unnecessary waste; So this kind tailor-(made) coating need reach LV: 500-1200 mPa.s/25 ℃; High trickling: can fill fast after applying, from levelling, can guarantee that coating can sprawl in use fast, filleting can also satisfy the spraying application requirement simultaneously in very narrow electronic devices and components slit;
2, can fast setting under the room temperature: as the flow line production operation, be to guarantee working efficiency, need this kind tailor-(made) coating can be at ambient temperature; Surface drying time is at 10-30 minute (25 ℃, 50 %), just admittedly time 5-15 hour (25 ℃; 50 %); If can not fast setting, can cause the waste of plenty of time in the workflow, influence production efficiency;
3, product reaches environmental requirement: because apply construction is in the workshop, to construct, and product should select neutrality to take off the ketoxime system, selects the solvent of low smell low toxicity;
4, good to substrate bonding property: the cementability good to base material, could guarantee coating curing after, be difficult for being stripped from, play the protection insulating effect;
5, the coating H.T. after solidifying: have only that strength of coating after the curing is high, hardness is low, elongation good, the toughness of coating is better, in use is difficult for being damaged.
Therefore, a kind of exploitation of room temperature vulcanization organosilicon elastic coating of easy to use, high performance-price ratio necessitates.
