Description
Technical field
The present invention relates to coating, more particularly to subbing, specifically a kind of quick-drying ultraviolet light solidification back cover applies
Material and preparation method thereof.
Background technology
With the improvement of living standards, building coating by the past for the purpose of protecting wall, decoration towards attractive in appearance graceful, resistance to
It is dirty and with the multifunctions such as automatically cleaning, can heat insulating reflecting greenization direction develop.Such as cement plate be must in construction project
Indispensable construction material, but want to need to pre-process in the enterprising one-step functional of shaggy cement plate, and use is specialized in
Cement plate can increase cost.Main solution is to use basic unit's alkali resistance seal coat at this stage, and its weak point has (1)
Drying time is long, it is necessary to wait solvent could carry out next process after fully volatilizing, and brings and stagnates and numb to production and construction
It is tired.(2) priming paint having is not strong to cement plate adhesive force, is peeled off and pine through having after a period of time, between decorative cover and cement plate
Relaxation phenomenon；(3) coating surface densification flatness is small, permeability is big, it is impossible to efficiently reduces the coating surface additional waterproof, anti-
Penetrate, the waste of the functional material such as heat-insulation and heat-preservation.Therefore, it is badly in need of a kind of quick-drying ultraviolet light solidification back cover coating of research and development,
Produce and construct stagnation etc. more than solving the problems, such as, has important social effect and economic value.
The content of the invention
It is contemplated that being grown for drying time existing for existing back cover coating, free settling asks in coating storage, construction
A kind of topic, there is provided ultraviolet light solidification back cover coating that is quick-drying, being not easy sedimentation separation.
In order to solve the above technical problems, technical scheme provided by the invention is：
A kind of quick-drying ultraviolet light solidification back cover coating, raw material components are according to the mass fraction：
The prepolymer is epoxy acrylic resin, modified epoxy acrylate resin, acid epoxy acrylic resin, fragrance
One or more in the poly- acrylate of ammonia three of adoption ether type, low-viscosity bisphenol A epoxy diacrylate fat, mass fraction are preferred
55%.
The diluting monomer is 1,6 hexanediol diacrylate (HDDA) and/or trimethylolpropane trimethacrylate
(TMPTA), mass fraction preferably 40%；
The light trigger is 1- hydroxy-cyclohexyls propiophenone (1173), mass fraction preferably 3%；
The auxiliary agent is conventional defoamer, thickener and anti-settling agent；
The filler be talcum powder, dicalcium powder, mica powder, blanc fixe and with the one or more in wollastonite in powder；
It is preferred that talcum powder 10-15, dicalcium powder 10-15, mica powder 10-15 according to the mass fraction.
A kind of preparation method of quick-drying ultraviolet light solidification back cover coating, comprises the following steps：
Step 1：Matched according to above-mentioned mass fraction, weigh prepolymer, diluting monomer, light trigger, triethanolamine, added
In reactor, rotating speed is adjusted to 400-500rpm, stirring 5min forms transparent mixture；
Step 2：Rotating speed is reduced to 200-300rpm, filler is slowly added to, until being done again without obvious in transparent mixture
Rotating speed is raised during dry fleut to 1500-2000rpm, adds auxiliary agent, ultraviolet-curing paint is made in stirring 30min.
A kind of coating method of quick-drying ultraviolet light solidification back cover coating, base material bottom is coated in by the coating with spreader
On plate, film thickness 100-125um, with the speed of 4-5 rice per minute, by ultra-violet curing instrument illumination curing 3-5 seconds.
The back cover coating of above-mentioned coating is subjected to the performance tests such as cured film adhesive force (the results are shown in Table 1) after 3 days.
The ultraviolet-curing paint 30ml of above-mentioned gained is fitted into 50ml Clear glass bottles and jars, it is quiet at room temperature after sealing
Put, after 2 days, one month, 2 months, observe the sedimentation separation situation (the results are shown in Table 1) of coating from the appearance.
The beneficial effect of coating of the present invention compared with prior art：
Present invention utilizes UV-curing technology, gained paint solidification speed is fast, cured film being capable of rapid draing；Utilize
The needle-like and filamentary structure of talcum powder, enhance the adhesive force of cured film；It make use of the elastic flakey that mica powder has
Structure, lain down before solidification by the effect of surface tension, automatically form state parallel to each other, reduce the permeable of cured film
Property；In the system of the multiphase mixture of sticky liquid resin, thin diluting monomer and a small amount of auxiliary agent composition, by talcum powder
The dicalcium powder light with granularity corpusculum is used cooperatively with mica powder, forms the stabilising system of interaction, can not only be improved solid
Change the adhesive force of film, also effectively inhibit the settleability of coating.Coating surface has excellent compactness and flatness simultaneously, Gu
Changing film has acidproof, alkaline-resisting and salt tolerant characteristic, and preparation method is simple.
