Abstract
The invention is a kind of solid lacker stained withpeak,which buildup is single and made up of epoxy acrylic resin as ac oligomerization, third-hydroxymethyl-propane, and third-acryate as ac releasing agent, NO.3136 alkide resin, photosensitizer and so on. The lacker has many strongpoints, for example, high curing speed, good effect, chubby coping, high ashesion and no desquamating, because the compounding formula is advisability, especially mixed with photochromic. stainded with the top of vimineous material like pencils, the lacker will change into solid under the black light within 20 seconds and be free from the dampness, so, the drying time is shorter and surface quality and the production efficiency of the pencils will be improved. The NO.3136 alkide resin can improves the binding energy between the lacker and the coating substance, in this way, the cost will be lower.
Description
Affiliated technical field
The present invention relates to its physical properties is the coating composition of feature, and relates to a kind of photocuring more specifically and be stained with top lacquer.
Background technology
Prior art is to the elongated rod-shaped thing, when for example the top of pencil imposes on coated, be to be stained with top technology in the pencil manufacturing processed, all be to adopt traditional pyroxylin(e)finish, when adopting this paint, the whole top technology of being stained with need be divided and finished for three times, be stained with at every turn must wait behind the top to paint just can descend after the drying together be stained with the top operation, but the time of drying of pyroxylin(e)finish is longer, on average needs 2 hours approximately at every turn.If run into than wet weather, indoor humidity is higher, and the not only dry required time is longer, also can have influence on the quality of being stained with the top.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the photocuring that the invention provides a kind of single-component is stained with the top lacquer.It is formulated by active copolymer, reactive thinner, photosensitizers, resin etc.This is stained with top lacquer, and to have a curing speed fast, between 30 minutes to 1 hour, and can be dry; The sticking power of lacquer is good, is stained with thin wood pole shape object, and it is plentiful to be stained with lacquer as the top of pencil, and does not have peeling phenomenon, has the excellent effect of high-efficiency high-quality.
Photocuring of the present invention is stained with the top lacquer and is formed by following prescription:
| Constituent | Weight percent (%) |
| Active copolymer | ????27～40 |
| Reactive thinner | ????40～53 |
| Resin | ????20 |
| Photosensitizers (adding in addition) | ????1～2 |
Each constituent all is the commercial goods in the above-mentioned prescription.
Active copolymer is commercially available epoxy acrylic resin, and it is the topmost composition of photo-curing paint, is subjected to can solidify behind the light action.
Reactive thinner is one or more the mixture in commercially available Viscoat 295 (being called for short TMPTA), the tripropylene glycol diacrylate (being called for short TPGDA).It is a kind of viscosity reducers.
Resin is 3136 commercially available Synolac, and it both had bonding force preferably with timber, can help again reducing cost.Photosensitizers is commercially available 2-hydroxy-2-methyl-1-phenyl-1-acetone, one or more the mixture in 1-hydroxyl-cyclohexyl-phenyl ketone.It is an excited molecule, under the irradiation of ultraviolet light, produces transition of electron, is in excited state, and then decomposes free radical, and trigger monomer and prepolymerization are photochemically reactive prerequisites.
The invention has the beneficial effects as follows, adopt reasonable scientific formula, overcome the shortcoming that exists in the prior art, described photocuring is stained with the top lacquer, and illumination after fixing speed is fast, and is effective, and the top is plentiful, and sticking power is good, does not have peeling phenomenon.Be stained with behind the top of elongated rod-shaped thing such as pencil, under ultraviolet illumination, only need 20 seconds promptly curable, shortened time of drying greatly, and be not subjected to the influence of weather humidity, can finish, improved the surface quality and the production efficiency of pencil as long as be stained with once needed color lacquer again.
Embodiment
The following examples will the invention will be further elaborated, can more intactly understand the present invention and see advantage of the present invention, but not limit the scope of the invention.
| Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| Epoxy acrylic resin | ????32 | ????27 | ????40 |
| Viscoat 295 (TMPTA) | ????48 | ????53 | ????40 |
| 3136 Synolac | ????20 | ????20 | ????20 |
| Photosensitizers (adding in addition) | ????1 | ????1 | ????1 |
Be stained with the top lacquer by the photocuring of this formulated, the curing speed that coats with lacquer after the illumination is fast, and is effective, and the top is plentiful, and sticking power is good, does not have peeling phenomenon.Use photocuring of the present invention to be stained with the pencil of top lacquer, can be stained with the pencil lacquer of required color after the curing at once, this moment, the color paint of institute's coated can be dry between 30 minutes to 1 hour, so not only improved the pencil quality, but also improved pencil production efficiency greatly.
The viscosity that photocuring is stained with the top lacquer can change along with changes of seasons.For this reason, should increase thinner in the winter time and be stained with the viscosity of top lacquer, should increase resin content in summer and be stained with the viscosity of top lacquer to improve photocuring to reduce photocuring.In order to improve the cost that photocuring is stained with the sticking power of top lacquer and is reduced product, 20% 3136 Synolac have been selected in the formula for a product for use simultaneously.
